Abstract

Young coconut fruit is an agricultural commodity with high economic value. The utilization of young coconuts needs to be followed up with post-harvest handling, such as preservation, packaging, and storage because young coconuts are easily damaged. Currently, young coconut consumption is starting to increase because it is widely used as a toxin neutralizer or consumed to maintain body health and fitness. The problem that occurs among young coconut ice sellers is how to deal with young coconut shell waste. Therefore, there is a need for innovation that can help young coconut ice sellers to handle waste from young coconuts and turn the coconut waste into something useful. The solution for processing young coconut waste in this community service activity is carried out by processing young coconut waste into ready-to-use organic fertilizer and planting media. In addition to overcoming the problem of young coconut waste, this activity is aimed at enabling the Women Farmers Group to be able to utilize young coconut waste to be used as organic fertilizer and planting media by applying appropriate technology to reduce the impact of environmental pollution due to the abundance of this waste. As the results of these activities, the women farmer groups have been able to utilize young coconut waste to be used as material for making organic fertilizer and planting media which were initially not of economic value by using a chopping machine, so as to reduce the impact of environmental pollution caused by the abundance of this waste.

Abstract

Soil arthropods play an important role in nutrient cycling and maintenance of soil structure. Thus, their abundance and diver­sity can indicate the biological quality of the soil. Due to different soil management practices, arthropods are also very sensitive to en­vironmental changes. This study aims to analyze the abundance and diversity of soil arthropods and the environmental factors that sup­port the abundance of soil arthropods in terrestrial of Situ Lengkong Panjalu, West Java, Indonesia. The methods used to obtain samples of soil arthropods are pitfall trap. Soil arthropod data were analyzed to determine the Shannon diversity index (H'), Margalef richness index (R), and Evenness index (E). The effect of abiotic environmental fac­tors was analyzed using Principal Component Analysis (PCA). A total of 1263 arthropods were found in Situ Lengkong Panjalu, belonging to 11 orders, 24 families, and 32 morphospecies. The current work determined the scores of H'= 2.08, R = 3,08, and E = 0.72 of soil arthropods in Situ Lengkong Panjalu, West Java, Indonesia. Results revealed that humidity is one such environmental parameter affecting the presence of soil arthropods in Situ Lengkong Panjalu, West Java, Indonesia. This research can be used as a guide in validating and conservation of the habitat of soil arthropod species on West Java

Abstract

This study aimed to identify the species of Lepidopteran predators that prey on soft scale insects (Coccidae) found on coffee plants in Sigi Regency using molecular techniques. DNA was extracted using the modified CTAB method (Doyle & Doyle, 1990). PCR amplification targeted the COI gene using universal primers LCO1490 and HCO2198 with a GeneAmp PCR System 9700. Visualization was done using 1% agarose gel and UV-transilluminator. Sequencing was conducted externally. Data were analyzed using BioEdit 7.2.5, BLAST, BOLD Systems, and MEGA11 software. The DNA sequence of the predator sample showed 97.91% similarity to Autoba rubra based on GenBank and 97.59% in BOLD Systems. Phylogenetic analysis confirmed a close genetic relationship with A. rubra, distinct from Eublemma. Morphological similarities with Eublemma were misleading, highlighting the accuracy of molecular identification. This study is the first to confirm the identity of a Lepidopteran predator of coffee scale insects in Indonesia using molecular techniques, revealing its close relation to Autoba rubra. The results correct previous morphological misidentifications and contribute new data on predator diversity in biological control contexts.

Abstract

The Javan surili (Presbytis comata), a keystone species in the tropical rainforest ecosystem of Java Island, is facing serious threats from deforestation, hunting, and habitat fragmentation. As an endemic species with a highly restricted, particularly on the island of Java, research on the Javan surili remains considerably limited. Hence, its geographical location and distribution patterns are still not clearly understood. Our literature review aims to determine the current status of the Javan surili and the factors influencing its population decline, as well as to evaluate the effectiveness of various conservation strategies that have been implemented. These findings highlight the importance of a multidisciplinary approach in Javan surili conservation efforts and provide policy recommendations to improve the success of species conservation, especially in its native habitat. Immediate conservation efforts and attention from the primatologist, relevant authorities, and stakeholders are needed to prevent the localized extinction of Javan surili.

Abstract

This study investigates vegetation diversity within the agroforestry system of Kuta Traditional Village, West Java, Indonesia, a community renowned for its long standing integration of ecological principles and cultural traditions in land management. Twenty plots (20 m × 20 m) were purposively established to assess vegetation structure across four growth stages: trees, poles, saplings, and seedlings. Data collection includes the number of species and the number of individuals of each species, followed by the calculation of the Important Value Index (IVI), Shannon–Wiener diversity index (H′), Margalef species richness index (R), and Pielou’s evenness index (E). Results indicated that Cocos nucifera and Arenga pinnata dominated the mature tree stage, while Coffea canephora prevailed at the pole stage. High diversity (H′ = 2.91–3.41) and richness (R = 5.13–6.23) were observed in trees, poles, and saplings, reflecting balanced community structures and sustainable regeneration. The seedling stage exhibited lower diversity (H′ = 2.67, R = 2.96) despite high evenness (E = 0.96), suggesting selective recruitment patterns. Principal Component Analysis revealed soil pH as the most influential environmental factor shaping species distribution. These findings underscore the importance of traditional agroforestry in sustaining biodiversity, supporting livelihoods, and maintaining ecological resilience, thereby highlighting its significance as a model for sustainable land use and biodiversity conservation in culturally significant landscapes.

Abstract

Kurangnya keterlibatan siswa dan rendahnya pencapaian hasil belajar dalam mata pelajaran biologi, dimana metode pembelajaran tradisional masih mendominasi menjadi perhatian dalam penelitian ini. Adapun tujuan dari penelitian ini adalah untuk mengetahui pengaruh penggunaan model Problem Based Learning (PBL) yang digabungkan dengan aplikasi Kahoot terhadap peningkatan hasil belajar kognitif siswa pada topik system gerak manusia. Penelitian ini menggunakan pendekatan kuantitatif dengan metode eksperimen semu dan desain one group pretest-posttest. Subjek pada penelitian ini terdiri dari 34 siswa kelas XI-2 Madrasah Aliyah Negeri 1 Majalengka. Data  didapatkan melalui tes pretest dan posttest dalam bentuk pilihan ganda yang dianalisis menggunakan nilai rata-rata pretest sebesar 49,42 menjadi 78,42 pada posttest, dengan nilau N-Gain sebesar 0,60 (kategori sedang). Uji hipotesis menunjukkan bahwa nilai Zhitung lebih besar dari Ztabel, yang berarti terdapat pengaruh signifikan dari penerapan model PBL berbantuan Kahoot terhadap hasil belajar kognitif siswa. Simpulan dari penelitian ini menunjukkan bahwa model PBL berbantuan Kahoot dapat meningkatkan pemahaman siswa secara aktif, interaktif, dan menyenangkan, serta direkomendasikan untuk diterapkan dalam pembelajaran Biologi pada materi lain yang menuntut pemahaman konseptual tinggi.
