Abstract

Kegiatan Pengabdian kepada Masyarakat (PKM) ini merancang dan mengimplementasikan model pemberdayaan berbasis civic engagement melalui praktik pertanian modern (hidroponik) untuk membangun kesadaran lingkungan di kawasan wisata Pemandian Karang Anyer, Kabupaten Simalungun. Desain yang digunakan ialah One Group Pretest–Posttest meliputi survei awal, pelatihan teori–praktik, serta pendampingan intensif selama delapan minggu. Hasil menunjukkan peningkatan signifikan pengetahuan teknis peserta (87% mampu menjelaskan kembali konsep hidroponik, nutrisi, dan irigasi hemat air), pembentukan kelompok tani kecil, serta terbangunnya komitmen pengelolaan limbah rumah tangga secara lebih ramah lingkungan (92% responden mengurangi pupuk kimia). Demplot hidroponik seluas ±300 m² menghasilkan panen perdana ±75 kg sayuran yang dimanfaatkan untuk konsumsi dan dijual di pasar lokal sehingga menambah kas kelompok. Tantangan teknis, sosial, logistik, dan cuaca dimitigasi melalui adaptasi teknologi, pendekatan partisipatif, dan dukungan pemerintah desa. Temuan menegaskan bahwa integrasi civic engagement dengan pertanian modern tidak hanya meningkatkan keterampilan dan pendapatan, tetapi juga memperkuat solidaritas sosial dan ekoliterasi warga, sekaligus mengaitkan sektor pertanian dengan nilai tambah pariwisata berkelanjutan. Model ini direkomendasikan untuk direplikasi dengan mempertimbangkan konteks lokal dan kemitraan triple helix (pemerintah–kampus–dunia usaha).

Abstract

School is an educational institution in charge of meeting the educational goals that have been entrusted through law. Therefore, efforts are needed to improve the educational quality based on students' achievement, which can be carried out through various ways by the stakeholders in the educational institution. The current research was conducted to identify the relationship between the use of learning facilities and science learning achievement. The method applied is descriptive quantitative using questionnaire data and deep interviews. The total population involved is 407 students, of which 186 of them were selected as the research samples using Proportional Stratified Random Sampling technique. Based on the research, it was revealed that there was a positive relationship between the use of learning facilities and science learning achievement, which is indicated by the correlation test of rxy (0.180) > rtab (0.143). Furthermore, the deep interviews showed that students had difficulty in learning science because there were no laboratory facilities for the practicum as well as the limited infocus tools of only two units of audio-visual media. However, the teacher's improvisation in performing the practicum was categorized as quite good. Eventually, it can be summed up that learning facilities are one of the determining factors in improving student achievement. In this case, it is suggested for further research to add other variables to support the improvement of student achievement.

Abstract

Invasive alien plants pose a major threat to biodiversity, particularly in conservation areas embedded within industrial plantation forest landscapes dominated by exotic species. This study aimed to analyze the composition and dominance of invasive plants, community similarity, and their correlations with Acacia mangium and Eucalyptus pellita stands in the Protected Area of PT Musi Hutan Persada, South Sumatra. Vegetation analysis was conducted using a nested quadrat sampling method across four stand types (control, A. mangium-dominated, E. pellita-dominated, and mixed stands), with 60 purposively selected plots. Data were analyzed using the Important Value Index (INP), Jaccard similarity index, and Spearman correlation. The results identified 20 invasive plant species, with Eleusine indica as the most abundant. A. mangium and E. pellita exhibited the highest INP at the tree stratum. Similarity analysis indicated variation in species composition, with a tendency toward community homogenization in some locations (≥0.80). Correlation analysis revealed that A. mangium was positively associated with Imperata cylindrica and Chromolaena odorata, while E. pellita was associated with Clidemia hirta and Piper aduncum. These findings highlight the ecological role of exotic stands in shaping the distribution patterns of invasive plants.

Abstract

Invasive weeds possess high adaptability and dispersal capacity, enabling them to alter plant community structure across various agroecosystems, including rubber plantations. This study aimed to identify invasive weed species and analyze their dominance based on the Summed Dominance Ratio (SDR) in a rubber plantation in Gandus Subdistrict, Palembang City. The study employed vegetation analysis using a purposive sampling method with quadrat transects across three observation zones (front, middle, and back of the plantation), each consisting of seven plots measuring 2 × 2 m. Vegetation parameters analyzed included relative density, relative frequency, importance value, and SDR. The results recorded 15 weed species from 8 families with a total of 315 individuals, with Asteraceae representing the most dominant family in terms of species richness. SDR analysis indicated that Rolandra fruticosa was the most dominant species (28.27%), followed by Asystasia gangetica, Digitaria ciliaris, Ageratum conyzoides, and Synedrella nodiflora. The dominance of these species reflects high ecological pressure within the rubber plantation agroecosystem, facilitating the proliferation of invasive weeds. These findings provide baseline information on weed community structure and can serve as a reference for developing more effective weed management strategies in rubber plantations.

Abstract

 The search for new therapeutic agents has increasingly focused on bioactive compounds from sponge-associated bacteria. This study investigated bacterial symbionts of marine sponges collected from the mangrove ecosystem of Tanjung Tiram, Southeast Sulawesi, which have not been previously explored for their bioactive potential. Thirty bacterial isolates were screened in triplicate for antibacterial, antioxidant, antidiabetic, and antibiofilm activities. Antibacterial activity was evaluated using the disc diffusion method, antioxidant capacity by DPPH radical scavenging assay, α-glucosidase inhibition for antidiabetic potential, and antibiofilm activity by the crystal violet binding method. Several isolates showed notable bioactivities: strain Sp.8 produced the largest inhibition zone against Escherichia coli (15 mm), and Sp.14 showed the strongest inhibition against Staphylococcus aureus (23 mm). The most active antioxidant strains (Sp.14, Sp.15, Sp.13, and Sp.6) exhibited radical scavenging activity above 80%, while Sp.13, Sp.15, Sp.31, and Sp.37 showed high α-glucosidase inhibition (>74%). Strains Sp.38 and Sp.12 significantly reduced biofilm formation by E. coli and S. aureus, respectively. These findings reveal the untapped potential of sponge-associated marine bacteria from Tanjung Tiram as promising sources of bioactive metabolites for future drug discovery.
