Bamboo is a useful plant that holds significant cultural and economic importance, particularly in small Indonesian islands like Peleng Island in Central Sulawesi. This paper explores bamboo utilization on Peleng Island, aiming to broaden our understanding of bamboo use on small Indonesian islands and shed light on local wisdom in bamboo utilization. The research was conducted on Peleng Island in 2019. Information on bamboo utilization was gathered through in-depth interviews with residents. Bamboo materials were collected and sent to the Herbarium Bogoriense for identification. The data were analysed descriptively. There are six bamboo species utilized on Peleng Island, namely Bambusa vulgaris, Dendrocalamus asper, Gigantochloa atter, Neololeba atra, Schizostachyum brachycladum, and Schizostachyum lima. Bamboo on Peleng Island is used for building materials (roofs, pillars, and wall weaving), cooking traditional foods like nasi jaha and bambu suman, and for various other uses (ornamental plants, water containers, stairs, poles for picking fruits/cloves, pest traps, and fish trap).

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

Research works were carried out from 2012 – 2015 to investigate success of controlling broadleaved weed and trees of V.nilotica and planting desired grasses The tretments were combined 3 factors. Factor 1, was the way to apply triclopyr formulated as GARLON 670 EC to control trees of V.nilotica, (1). by brushing the solution of 1% GARLON 670 EC dissolved in diesel oil on the stump of V.nilotica after cutting using a chainsaw, and by (2). brushing at the base of intact standing tree of V. nilotica, from above the ground up to 30 cm height. Factor 2, was grasses (1). Dichanthium caricosum, and (2). Polytrias amaura planted ad 1 x 1 m2. Factor 3 was fertilizer, (1) planted grasses were fertilized with compost derived from goat feces at 100 gr/ single chunk planted, and (2) without fertilizer. The results indicated that grass grew better under the treatment of killing V.nilotica by cutting and brushing with 1% GARLON 670 EC dissolved in diesel oil, while fertilizing D.caricosum was much better to than of P.amaura.

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.

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.

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.

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.

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.

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.

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.
