Abstract

Kelompok Tani Taruna Mas Kelurahan Poboya Kota Palu merupakan kelompok tani aktif dalam melaksanakan usaha peternakan dan masih menggunakan pupuk serta pestisida kimia dalam proses budidaya pertaniannya. Limbah peternakan yang dihasilkan dari usaha tersebut saat ini belum termanfaatkan secara optimal, padahal berpotensi untuk digunakan sebagai bahan dasar pembuatan pupuk organik padat dan cair. Kegiatan Pengabdian Kepada Masyarakat (PKM) di Kelurahan Poboya bertujuan untuk memberikan motivasi, solusi dan meningkatkan pengetahuan, pemahaman, serta kecakapan kepada kelompok tani dalam pemanfaatan dan pembuatan limbah urin sapi menjadi pupuk organik cair yang ramah lingkungan melalui proses fermentasi. Adapun metode yang diterapkan dalam kegiatan PKM ini meliputi a) Pemberian Materi/Penyuluhan; b) Pelatihan dan Pendampingan; c) Tahapan Demonstrasi; d) Indikator Keberhasilan; e) Monitoring dan Evaluasi. Hasil kegiatan yang dilaksanakan berjalan baik sesuai dengan target tujuan yang diharapkan. Terjadi peningkatan pemahaman, pengetahuan serta keterampilan peserta yang signifikan sebesar 98%. Hal ini terlihat dari antusias selama proses kegiatan berlangsung serta setelah kegiatan berakhir melalui monitoring dan evaluasi. Pemanfaatan limbah urin sapi menjadi pupuk organik cair merupakan sebuah alternatif upaya dalam mengurangi ketergantungan petani terhadap penggunaan pupuk dan pestisida kimia.

Abstract

Soy milk kefir offers a plant-based alternative to dairy probiotics. This study aimed to enhance both the chemical and functional characteristics of soy milk kefir by evaluating the effects of varying kefir grain starter doses and added Clitoria ternatea (telang) flower juice. A 3x4 factorial design was employed using three starter levels (40g, 50g, 60g per liter soy milk) and four telang juice concentrations (0ml, 10ml, 20ml, 30ml per liter). Key parameters analyzed post-fermentation included protein content (Kjeldahl), lactic acid (titration), pH, Water Holding Capacity (WHC, centrifugation), anthocyanin content (differential pH method), and Lactic Acid Bacteria (LAB) count (plate count). Results indicated significant (p<0.05) effects of both starter dose and telang juice concentration, and their interaction, on all measured characteristics. Specifically, the 40g starter + 30ml juice treatment yielded the highest protein (39.35%) and anthocyanin (18.42 mg/mL). The 50g starter + 20ml juice treatment showed the highest WHC (67.30%). The 60g starter + 30ml juice treatment produced the highest lactic acid (20.30%). Higher LAB counts were observed in several treatments including A0B0, A1B1, A2B2, and A2B3 compared to others. In conclusion, optimizing kefir grain dosage and adding telang flower juice significantly improves soy milk kefir's nutritional profile (protein) and functional attributes (anthocyanins, WHC, LAB), demonstrating its potential as an enhanced plant-based functional food.

Abstract

The challenge in science education is to connect biotechnology concepts with real-world contexts and local potential. This study aims to explore and identify local entomopathogenic microbes as innovative learning resources on the topic of agricultural biotechnology, specifically biological control of onion pests.  This exploratory study includes field surveys in the onion centre of Guntarano Village and laboratory analysis. Isolation of entomopathogenic fungi from infected Liriomyza spp. larvae was carried out using the insect bait method. The isolates obtained were purified, identified based on morphological characteristics (macroscopic and microscopic), and their spore density was calculated. The exploration successfully screened six potential fungal isolates. Morphological identification revealed the presence of Aspergillus flavus, Aspergillus niger, Trichoderma sp., and one isolate suspected to be Metarhizium sp. All isolates had high spore densities (> 10⁷ conidia/mL), with the Metarhizium sp. (Larva 4) and A. niger (Larva 2) isolates showing the highest densities. The diversity of entomopathogenic microbes found has the potential to be a source of biopesticide learning in science education. This material can be utilised to develop modules, worksheets, or learning media based on local potential to enhance science literacy and students' understanding of agricultural biotechnology
