Comparative Review of Bioinformatics and Wheat Protoplast Assays for Effector Identification in Pathogenic Fungi
type: item
description: Fungal effectors are key pathogenicity factors, but their identification in wheat pathogens is challenging due to lack of conserved motifs and rapid evolution. This review compares two complementary approaches for effector discovery: bioinformatics pipelines for large-scale in silico prediction and wheat protoplast assays for functional validation in a homologous host system. We analyze the strengths, limitations, and complementarity of each method, and propose an integrated, iterative workflow that sequentially leverages computational prediction and experimental screening. This synergistic strategy accelerates the accurate identification of effectors and their cognate resistance genes, providing a critical foundation for breeding durable disease-resistant wheat varieties and enhancing global food security.

Jakarta’s Urban Green Spaces as Butterfly Habitats and Its Implications for Climate Mitigation
type: item
description: Jakarta’s urban green spaces are more than city parks. They are small ecosystems alive with pollinators that keep urban nature functioning. To understand how vegetation and human activity influence butterfly diversity, this study surveyed five parks across the city using standardized observation methods, namely the Pollard Walk and Point Count. A total of 157 butterflies representing 22 species were recorded, with Eurema sp. appearing most frequently. Parks with lush, layered vegetation like Penjaringan Urban Forest Park hosted the most species, while heavily urbanized areas had fewer. The findings reveal that preserving diverse plants and reducing disturbance can make cities more resilient to climate change, one butterfly at a time.

Guardians of the Forest Floor: Learning Conservation from the Asian Forest Tortoise (Manouria emys)
type: item
description: Deep within the tropical forests of Southeast Asia, the Asian forest tortoise (Manouria emys) moves with the quiet memory of millions of years. Yet today, its path is threatened by deforestation, illegal trade, and a warming climate. In Bengkulu, Indonesia, the University of Bengkulu’s ex-situ program has successfully increased the survival and breeding success of rescued tortoises, providing controlled habitats where health, behavior, and reproduction can be monitored. Supported by collaboration with the University of North Carolina Greensboro, the program rehabilitates confiscated individuals and prepares them for long-term population recovery. Beyond protecting a species, this initiative transforms conservation into education, where the tortoise becomes a living teacher of patience, empathy, and coexistence.

Ecosystem Restoration and Conservation in Singkarak Lake Protection Area: Impacts of Reclamation
type: item
description: Reclamation and landfilling activities within protected zones pose serious threats to ecosystem sustainability by altering natural land–water interactions and violating the essential functions of Singkarak Lake’s riparian buffer. This study aims to map the extent of reclamation, examine legal violations related to spatial and environmental permits, and assess ecological and economic losses. A mixed-methods approach was used, including geospatial analysis, normative legal review, and ecocentric valuation of environmental damage. Results show that 2,976 m² of land was illegally reclaimed within the protected lake boundary. Overlay with the regional spatial plan confirms non-compliance with zoning regulations and the absence of required permits. The total estimated loss amounts to Rp 3,383,291,152, largely driven by disrupted hydrological functions and reduced land utility.

Innovative Utilization of Agricultural Waste for Sustainable Bio-Based Materials Development
type: item
description: Agricultural waste poses serious environmental challenges while offering untapped opportunities for bio-based innovation. This aim study is to evaluate an integrated process for converting agricultural residues (rice husks, corn cobs, and sugarcane bagasse) into sustainable bio-based composites. We applied pyrolysis (450–500 °C), biocomposite synthesis, and green-chemistry techniques to produce and characterize novel biomass-derived materials. The resulting composites exhibited high thermal stability (≈280 °C) and tensile strength (15–28 MPa), highlighting their potential as alternatives to petroleum-based plastics. This approach also reduced open burning and carbon emissions by about 35%, supporting biodiversity, bioenergy development, and SDG 12 (responsible consumption and production). These findings demonstrate a viable pathway for valorizing agricultural waste in a circular bio-based economy.

Bioconversion of Oil Palm Waste into Protein-Based Bioplastic Using BSF (Hermetia illucens) Larvae
type: item
description: This study addressed the environmental challenge of palm oil waste by utilizing Oil Palm Empty Fruit Bunch (OPEFB) and Oil Palm Kernel Cake (OPKC) as substrates for Hermetia illucens (Black Soldier Fly) larvae bioconversion. The larvae were cultivated after OPEFB pre-treatment through milling, hydrolysis, and saccharification with Aspergillus niger to enhance digestibility. Protein extracted from larvae was used to produce protein-based bioplastics. Result showed consistent larval growth and consumption rates but variation in waste reduction efficiency, with the 7:3 substrate ratio yielding the highest reduction. Bioplastics exhibited good elasticity and biodegradability, while protein enrichment improved mechanical strength and reduced water absorption. This approach demonstrates a sustainable alternative for managing palm oil waste and producing eco-friendly bioplastics.

A Native Plant Offers Hope for Cleaner Water
type: item
description: Freshwater ecosystems around the world are under increasing pressure from pollution, climate change, and urban development. Finding affordable and environmentally friendly ways to treat polluted water is more important than ever. A recent study has turned to nature for help; specifically, to Limnocharis flava (yellow velvetleaf), a common aquatic plant native to Malaysia. We tested this plant’s natural ability to clean water by placing it in samples from a detention pond at Politeknik Sultan Idris Shah. Over the course of nine days, Limnocharis flava caused changes in key water quality indicators, including chemical oxygen demand (COD), turbidity, pH, total suspended solids (TSS), and dissolved oxygen (DO). The results were promising. Limnocharis flava noticeably improved water quality, showing that this humble plant could be a powerful ally in low-cost, sustainable water treatment efforts; especially intropical regions where it already thrives. Interesting results, indeed. Let’s dwell further!

Groundwater Guardians:
type: item
description: Kulon Progo Regency in Indonesia is home to a rich variety of geological features, an underground landscape that holds great promise for water resources like natural springs. Yet, in 2019, the community of Girimulyo Subdistrict faced a troubling clean water shortage, highlighting a growing need for smarter water management. To better understand where water is available and how it flows, researchers turned to modern mapping tools. Using Geographic Information System (GIS) technology, along with field surveys and measurements of spring water flow, scientists set out to chart the location and behavior of springs across the region. They used ArcGIS software and a method called Nearest Neighbor Analysis to uncover patterns in the data. What they found was surprising: springs in Kulon Progo do not follow a regular pattern; they appear scattered randomly across the landscape. The strength of each spring’s water flow also varied, depending on the land’s slope and the type of soil. These findings are not just academic. They offer a practical foundation for improving how the region manages its water; a critical step toward preventing future water crises and ensuring clean water access for all. Want to know more? Let’s read this!

The Unique Blue Curcumin
type: item
description: Curcumin, the active compound in turmeric, has long been known for its health benefits. However, did you know that there is a unique variant called Blue Curcumin? Due to its extraordinary potential, this compound has begun to attract the attention of researchers and the health industry. Blue curcumin has extensive health benefits, ranging from antioxidants to anti-inflammatory, antibacterial, and anticancer. In the pharmaceutical industry, blue turmeric can be developed into herbal medicines, cosmetics, essential oils, and health supplements. Identification of blue curcumin species is challenging due to its similarity to other species, color variations, and limitations of conventional identification methods. With a more scientific approach, such as DNA analysis, errors in identification can be reduced. We just started a study to validate the blue curcumin species using a DNA barcoding approach based on the ITS2, rpoC1, and trnH-psbA genes. A wide impact of our study ranges from strengthening species identification, utilization in pharmaceuticals, and increasing economic competitiveness, to biodiversity conservation. We do hope that this study will provide a comprehensive analysis that can help conserve and sustainably utilize this important resource.

The Effect of Mycorrhiza Application and Phosphorus Addition on AMF Spores Density and Pueraria javanica Growth
type: item
description: One of the suitable host plants for AMF (Arbuscular Mycorrhizal Fungi) is Pueraria javanica. Several factors that can affect the growth of P. javanica are the availability of nutrients and the activity of potential soil microbes, such as AMF. Applying potential soil microbes (AMF) to plants can increase plant growth, chlorophyll levels, and enzyme activity, and even improve soil quality. The ability of AMF to increase plant nutrient absorption causes plants with AMF tend to have optimum growth. The study aimed to understand the effect of AMF application and phosphorus (P) nutrients addition on AMF spore density and P. javanica growth. The experiment used a completely randomized design with one factor (formulation). Results of the study proved that phosphorus (P) addition was able to reduce AMF spore densities (Glomus etunicatum and Glomus mosseae) 3 weeks after application (WAA). The availability of P in a fairly high amount around the root area caused plants to reduce their dependence on AMF, which resulted in a decrease in AMF colonization and AMF spore densities. On the other hand, adding P nutrients proved to increase growth parameters (plant height and number of leaves) of P. javanica because AMF helped the absorption of P and received carbon from plants in return. Treatment P6 (G. etunicatum 10 g + without phosphorus) had the highest spore density value (400.33/10 g planting media), and treatment P9 (G. mosseae 10 g + phosphorus 10 ppm) showed the highest increase in plant height of 13.333 (P < 0.05) 3 weeks after application. Meanwhile, the maximum increase in the number of leaves occurred in plants that received 10 g of G. mosseae and 10 ppm of P every two days for three weeks. Studying AMF spore density can significantly improve plant growth, agronomic efficiency, and agricultural sustainability.

Ethnomedicinal Study and Phytochemistry Analysis of Antihypertensive and Anticholesterol Plants in Sukaharja Village, Lebak Regency, Banten Province, Indonesia
type: item
description: Medicinal plants are still used by people to treat many diseases, such as to lower cholesterol levels and hypertension. In Sukaharja Village, Lebak Regency, Banten Province, Indonesia, for example, the Baduy tribe still believe in practicing traditional medication. The village location is far away from the nearest health facilities. This ethnomedicinal study was conducted in the year 2023 by applying a quantitatively descriptive method. Data were collected by interviewing several respondents selected by purposive and snowball sampling methods. The list of plants was then verified by field observation, followed by species authentication, and use value (UV) calculation. Fresh samples of plants were made into simplicia and underwent phytochemical screening, including a TLC test, in a laboratory. From 50 respondents, we obtained information on 21 plant species used to lower cholesterol levels and for treating hypertension. The highest UV of plants used to lower cholesterol levels were Peperomia pellucida (0.56) and Annona muricata (0.52), while for treating hypertension were A. muricata (0.60), followed by Allium sativum (0.56). All of the plants used contained flavonoids, and selected plants examined by TLC test were revealed to be similar to quercetin. Traditional medication practices need to be preserved, which is as important as conserving medicinal plants that are precious biodiversity in Indonesia.

Effectiveness of DNA Barcoding Primers in Red Algae (Rhodophyta) Identification
type: item
description: Red algae (Rhodophyta) are vital primary producers in marine ecosystems and are economically significant due to their wide use in food, pharmaceutical, and cosmetic industries. The significant utilization of red algae indicates that these organisms require conservation and protection from extinction, therefore, accurate identification is a must. Traditional morphological approaches face challenges due to their simplicity and plasticity; however, molecular techniques, such as DNA barcoding can overcome these limitations. This study evaluated the effectiveness of using ITS1, Cox2-3, rbcL 1, and rbcL 2 primers for barcoding seven red algae species, focusing on amplification success and sequencing quality. All of the above-mentioned primers have demonstrated a noteworthy amplification rate of success, with 100% efficacy observed for ITS1 and rbcL 2. However, only Cox2-3, rbcL 1, and rbcL 2 primers exhibited a high-quality read based on the sequencing quality score, indicating their reliability in capturing the target sequence for identification. The results strongly suggested that rbcL 2 is the optimal choice for identifying Rhodophyta due to its high amplification rate and high-quality sequencing results.

Spore Production and Inoculum Formulation of Claroideoglomus Etunicatum and its Application in Maize (Zea Mays)
type: item
description: Recently, the demand for AMF (Arbuscular Mycorrhiza Fungi) fertilizer for agriculture, plantation, and forestry in Indonesia has been very high. Meanwhile, the unavailability of an applicable AMF inoculum that's easy to use and inexpensive is one of the constraints on AMF application as a fertilizer in the field. It indicates that the best formulated inoculum must be found. The study aimed to produce AMF spores using conventional and hydroponic system, formulate the best AMF inoculum, and measure the growth response in maize (Zea mays) after applying the formulated inoculum. In the formulation stage, the study was designed using a Completely Randomized Design (CRD) with 1 factor. The factor was the type of formulation. Data were analyzed using SAS software version 9 and further tested using Duncan's Multiple Range Test (DMRT) at 5% alpha (α) level. The results reported that the conventional pot culture technique (CVNE2) treatment that had been inoculated by Claroideoglomus etunicatum produced the highest spore density amount of 350 ± 6.97 per 10 g of zeolites (P<0.05). On the other hand, the hydroponic NFT (NFTE2) treatment that had been inoculated by C. etunicatum obtained the highest AMF percent colonization amount of 98% ± 2.66% (P<0.05). Analysis of variance in the formulation stage showed TZ60F1 treatment had a significant effect (P<0.05) in increasing plant height, the number of leaves, and dry weight of Zea mays, respectively 120 cm ± 1.7 cm; 15 ± 0.84; 26.3 g ± 2.46 g in 3 months after application.

The First Report on the Brachyuran Crab Diversity in Mandalika and Their Commercial Value
type: item
description: West Nusa Tenggara, Indonesia, encompasses the western part of the Lesser Sunda Islands with a long coastline that supports a rich biodiversity of coastal biota. Brachyuran crabs constitute one of the most diverse invertebrate groups in the coastal ecosystem. This research aimed to record the biodiversity of brachyuran crabs and their commercial value in the Special Economic Zone (SEZ) of Mandalika in Central Lombok, Indonesia. Data were collected by hand, scoop, and trap using the random sampling method. In the current study, we have compiled, for the first time, a checklist of 402 individual brachyuran crabs belonging to 22 genera, 13 families, and 35 species from Mandalika. The present study revealed that Mandalika has a comparable number of species to those in previous studies from other coastal areas on Lombok Island. The commercial value of the crabs is in line with their edibility. The family Ocypodidae comprised 43% of all the brachyuran crabs reported from Mandalika. The findings emphasise the importance of their habitat in Mandalika and the potency of brachyuran crabs to support government food security programs.

The Effect of Storage Period and Mixing Techniques on the Chemical Content of Environmentally Friendly BIOPOS Organic Compost at SEAMEO BIOTROP
type: item
description: SEAMEO BIOTROP produces daily waste from oyster mushroom baglog (Pleurotus ostreatus), dry organic waste that contains little water, such as dry leaves, grass straw, and citronella distilled waste. Managing oyster mushroom baglog waste, leaf waste, grass straw, and citronella distilled waste independently at SEAMEO BIOTROP as organic compost BIOPOS (BIOTROP Compost) is an environmentally friendly practice and can provide benefits both economically and ecologically. Apart from being carried out to protect biodiversity from decline, this study can also keep the soil system healthy and sustainable. The aim of this research is to: (1) make BIOPOS organic compost through the use of oyster mushroom baglog, leaf waste, leaf straw, and citronella distilled waste; (2) determine the influence of various types of BIOPOS organic compost (KT1, KT2, KT3) on the chemical content of compost. Research stages include: (1) creating BIOPOS organic compost, (2) measuring the chemical content of BIOPOS organic compost, and (3) measuring the effectiveness of BIOPOS. During the storage period of 30 dam up to 180 dam, BIOPOS organic compost which still contains N (0,54%), P (36,8%), K (7,23%) and complies with SNI 19-7030-2004 quality standards is KT3. In measuring C-Organic value, BIOPOS code KT2 with a storage period of 30 dam gained C-Organic amount of 28,36%, satisfying quality standards. The application of BIOPOS KT1, KT2, and KT3 with a pH range of 8,2- 8,3 high pH can be used to correct problems that often occur in acidic soils and is not effective when applied to sub-optimal alkaline soils because it will cause soil pH to increase sharply. Key words: BIOPOS, citronella distilled waste, grass straw, leaf waste, oyster mushroom baglog waste

The EFFECT OF POLYSTYRENE PAPER STYROFOAM FEED ON SURVIVORSHIP AND GROWTH OF Tenebrio molitor L.
type: item
description: Polystyrene Paper Styrofoam (PSP) styrofoam waste is one of the plastic waste that is difficult to degrade. However, from the recently research reported that the PSP styrofoam can be degradated by Tenebrio molitor L. The degradation depends on composition of PSP styrofoam as a part of feeding. This research was aimed to get the composition of good feed to increase the degradation rate of the PSP styrofoam waste, but it still had a good effect on the survivorship and growth of T molitor L. larvae. This research was an experimental laboratory and designed using a control and seven treatments with 3 replications. The parameters observed were survivorship, growth in body length, biomass, and waste degradation rate. The data obtained was analysed using Anova and Duncan test. The results showed that differences in PSP styrofoam waste feed had a significant effect on survivorship (p=0.00), on the growth of body length (p=0.002) and biomass (p=0.00), and waste degradation rate (p=0.02). The research revealed that lower the composition of PSP styrofoam and higher the composition of concentrate combination effected on increasing the survivorship, growth, and waste degradation rate. The result shows that 1 kg T molitor L. larvae can degrade 0.25 kg of PSP styrofoam waste for 60 days. The finding can be used to solve the problem according to the styrofoam pollution.

The EFFECT OF ORGANIC LEACHATE AND RICE WASHING WATER ON COMPOSTING TIME OF ORGANIC WASTE
type: item
description: Waste is an integral part of human life. The increase in population is one factor that increases the waste generated. The more the population, the more activities are carried out. Organic leachate and rice washing water are environmentally friendly compost activators and are easily obtained from daily activities. Composting is a waste management strategy. Composting is an organic method through the activity of microorganisms to decompose natural materials into materials, including humus. The purpose of this study was to determine the moisture content, temperature, pH, C/N ratio, and macro nutrients during the composting process. The physical parameters of compost from the three activator concentrations showed that the treatment of P3 (with the addition of leachate formulation 20 ml/kg and rice washing water 15 ml/kg) and P2 (with the formulation adding 20 ml/kg leachate and 10 ml rice washing water), the physical compost were brownish black in color, fine textured and smelled of soil on the 22nd day. The P3 treatment has met the quality criteria of compost according to SNI 19-7030-2004, the moisture content (30%), temperature (27°C), pH (6,8), C-Organic (32,9%), Nitrogen (1,42%), Phosphor (0,65%) and Potassium (1,63%). For the C/N ratio, the result of all treatments did not meet the quality criteria of compost according to SNI 19-7030-2004. The C/N ratio of all treatments showed that it is still above the maximum standard that has been set at 20.

Habitat suitability and niche interaction between the invasive snail Achatina fulica and its biocontrol flatworm Platydemus manokwari in Southeast Asia
type: item
description: Bioinvasions are increasingly altering community structures around the world, especially with the changing climate. In invaded areas, biocontrol agents are introduced to regulate the invasive species. However, without thorough evaluation, these agents can proliferate and threaten other organisms. We assessed the niche dynamics between invasive Achatina fulica (Giant African Snail) and its biocontrol agent, the Platydemus manokwari (New Guinea Flatworm), in Southeast Asia. Species occurrence and environmental data were used to model the habitat suitability of both species in the present and future climate scenarios using ecological niche modeling with the MaxEnt algorithm. These models predicted 25.9% and 42.0% of the current conditions to be suitable and 73.8% and 57.8% to be unsuitable for A. fulica and P. manokwari, respectively. There was a predicted steady increase in suitable areas and a gradual decrease in A. fulica’s unsuitable areas as the carbon emissions are predicted to increase. Moderate to high niche overlap of 61.2% to 83.4% was expected between the species under different climate scenarios. Predicting the suitable areas for invasive species and their niche interaction with other species in future scenarios will aid in identifying vulnerable areas for conservation.

Relative Protein Profile of Philippine cinnamomum (Schaeffer) Using Sodium Dodecyl Sulfate- Polyacrylamide Gel Electrophoresis (SDS-PAGE)
type: item
description: Philippine Cinnamomum are trees with aromatic leaves and bark. It has several economic and medicinal uses, but concerns about protein profile are limited. Thus, this study was conducted to determine the relative protein component of the species by Sodium Dodecyl Sulfate- Polyacrylamide Gel Electrophoresis (SDS-PAGE). A total of 27 cinnamon species were run in Sodium Dodecyl Sulphate - Polyacrylamide Gel Electrophoresis (SDS-Page) with LSB (Laemli Sample Buffer) and Tris HCI (1:1) as sample buffer. Determining protein profiles is a tool for the systematic classification of the species. Results showed that Philippine Cinnamomum leaf samples have the same component proteins. The SDS-PAGE provided a similar protein banding pattern, although the same bands' intensity varies. Pronounced protein bands were observed corresponding to 50 to 75 kDa and 25 kDa, with additional minor bands indicating a higher protein content. The results in SDS-PAGE showed that the component proteins of Cinnamomum leaves were comparable regardless of geographical source and different stages of growth of the samples. However, the concentration of some component proteins may vary, as indicated by the difference in intensity of protein bands. Sodium dodecyl sulphate Polyacrylamide gel electrophoresis (SDS-PAGE) is a tool in the biochemical method of determining the relative protein profile of Cinnamomum species. It can be used to classify plants up to the species level. Based on the study results, Philippine Cinnamomum has a higher protein content that can be used in culinary, medicinal, and pharmaceuticals.
