Abstract

This study evaluated the effect of additives in papaya leaf–based botanical pesticides on the vegetative growth of water spinach (Ipomoea reptans Poir). The experiment was arranged using a Randomized Complete Block Design (RCBD) with five treatments and five replications: P0 (control), P1 (papaya leaves), P2 (papaya leaves + garlic), P3 (papaya leaves + lemongrass), and P4 (papaya leaves + soursop leaves). Observed parameters included plant height, root length, number of leaves, and fresh weight. Data were analyzed using analysis of variance (ANOVA), Duncan’s Multiple Range Test (DMRT) at 5%, correlation, and multiple linear regression analyses. The treatments significantly affected most growth parameters. P3 (papaya leaves + lemongrass) produced the best performance, with plant height of 24.35 cm, root length of 22.58 cm, approximately 18 leaves, and fresh weight of 14 g. Correlation analysis showed strong positive relationships between plant height and number of leaves (r = 0.890), and between root length and fresh weight (r = 0.764). Regression analysis identified number of leaves as the strongest predictor of fresh weight (β = 1.015), followed by root length (β = 0.528), whereas plant height showed a negative effect (β = −0.891). Overall, the addition of lemongrass to papaya leaf–based botanical pesticides enhanced vegetative growth and biomass accumulation in water spinach plants.

Abstract

The processing of coconuts into Virgin Coconut Oil (VCO) is an alternative coconut processing method with strong potential for development in North Kalimantan, considering the region’s favorable environmental conditions for coconut cultivation. Over the past three years, coconut production in North Kalimantan has continued to decline, even though the number of productive coconut plantations remains relatively high. This decline in production is primarily attributed to the low bargaining price of fresh coconuts in the region. Therefore, alternative coconut processing strategies are needed to restore the economic value and purchasing power of coconuts. One promising coconut processing product is VCO. VCO can be produced using a fermentation technique that utilizes microorganisms present in yeast. In the fermentation-based VCO processing method, coconut milk is first allowed to settle until it forms a cream layer. The cream is then inoculated with yeast containing microorganisms such as Saccharomyces cerevisiae and Rhizopus oligosporus. These microorganisms produce protease and lipase enzymes, which hydrolyze the oil in the coconut cream with a high moisture content. Differences in processing techniques can influence the oil yield obtained. The use of yeast in VCO fermentation, combined with longer fermentation times, is expected to increase the yield. In this study, VCO was produced using yeast as a fermentation starter, and the resulting VCO was subsequently analyzed for quality. The experiment employed a Randomized Block Design (RBD). Two factors were observed: the type of yeast, consisting of V (without yeast), VR (bread yeast), and VT (tape yeast), and fermentation time, consisting of T1 (36 hours), T2 (48 hours), and T3 (60 hours). Each treatment was replicated three times, resulting in 9 treatments × 3 replications = 27 experimental units. The produced VCO was then analyzed for yield, as well as its physical and chemical properties. The results showed that treatment VRT3 (bread yeast with a fermentation time of 60 hours) produced the highest yield, reaching 25%. Furthermore, longer fermentation times resulted in higher VCO yields

Abstract

Kegiatan pengabdian masyarakat ini dilaksanakan di Kelurahan Selumit Pantai, Kecamatan Tarakan Tengah, yang selama ini menghadapi stigma negatif sebagai “kampung narkoba”. Permasalahan utama terletak pada minimnya aktivitas produktif dan keterbatasan lahan yang berimplikasi pada rendahnya kesejahteraan serta tingginya risiko sosial. Melalui pendekatan Participatory Action Research (PAR), program pelatihan hidroponik diterapkan sebagai solusi pemberdayaan berbasis partisipasi warga. Kegiatan mencakup Focus Group Discussion, pembangunan instalasi, penyemaian, pembuatan nutrisi, hingga panen. Hasil menunjukkan peningkatan keterampilan teknis, motivasi, serta munculnya aktivitas ekonomi rumah tangga melalui penjualan hasil hidroponik. Secara sosial, kegiatan ini berhasil memperkuat kohesi warga dan mengubah citra lingkungan menjadi lebih positif. Pelatihan hidroponik terbukti efektif sebagai strategi pemberdayaan masyarakat pesisir melalui peningkatan kapasitas, ketahanan pangan, dan transformasi sosial yang berkelanjutan.
