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

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

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.

Abstract

Program pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kapasitas Kelompok Wanita Tani (KWT) Melati 2 melalui pelatihan penggunaan alat modern dan penguatan strategi promosi offline dalam pengembangan produk olahan berbasis sumber daya lokal. Permasalahan utama yang dihadapi kelompok meliputi rendahnya standar higienitas produksi serta keterbatasan akses internet yang menghambat kegiatan pemasaran. Kegiatan pelatihan dilakukan melalui pendekatan partisipatif yang mencakup demonstrasi penggunaan alat modern seperti sealer otomatis, food dehydrator, baki stainless, serta penerapan prosedur operasional standar kebersihan dan sanitasi. Di samping itu, pelatihan promosi offline difokuskan pada pembuatan media cetak, strategi pemasaran dari mulut ke mulut, dan kerja sama dengan warung serta koperasi desa sebagai saluran distribusi produk. Data dikumpulkan melalui observasi, wawancara, angket, dan dokumentasi, kemudian dianalisis secara deskriptif kualitatif untuk mengidentifikasi perubahan pengetahuan, keterampilan, dan praktik anggota kelompok. Hasil kegiatan menunjukkan adanya peningkatan signifikan dalam pemahaman dan penerapan higienitas produksi, yang ditandai dengan kemasan lebih profesional, kualitas produk lebih stabil, serta proses pengolahan yang memenuhi standar sanitasi sederhana. Pada aspek pemasaran, strategi offline terbukti efektif dalam meningkatkan jangkauan pasar lokal meskipun terdapat keterbatasan infrastruktur digital. Produk KWT Melati 2 memperoleh perhatian lebih besar dari konsumen setelah penggunaan brosur, display produk, dan jaringan penjualan lokal. Secara keseluruhan, pendampingan ini memperkuat kapasitas teknis dan manajerial kelompok serta mendukung keberlanjutan usaha berbasis ekonomi kreatif pedesaan.
