Abstract

Kehadiran pupuk booster organik cair menjadi solusi bagi Kelompok Wanita Tani (KWT) dan masyarakat, karena lebih mudah dalam pengaplikasiannya dengan bahan baku yang tersedia secara lokal. Pemanfaatan limbah rumah tangga secara langsung dapat menjadi solusi dalam mengurangi dampak negatif penggunaan bahan kimia pertanian terhadap lingkungan dengan cara mengganti pupuk kimia dengan pupuk booster organik cair. Tujuan dari kegiatan pengabdian masyarakat ini adalah untuk memberdayakan anggota KWT dan masyarakat Desa Ibru melalui kegiatan community sharing dan pelatihan pembuatan pupuk booster organik cair untuk mengatasi permasalahan pertanian skala rumah tangga. Selain itu, untuk membantu meningkatkan keterampilan dan memberikan penghasilan tambahan bagi KWT. Langkah awal kegiatan melalui persiapan yang meliputi persiapan penentuan jadwal perpanjangan dan lokasi perluasan di Desa Ibru. Pelaksanaan kegiatan diawali dengan sosialisasi pengenalan pupuk booster kepada ibu-ibu KWT dan masyarakat di Desa Ibru. Untuk mengetahui pemahaman sosialisasi yang diberikan yaitu dengan memberikan pertanyaan seputar pembuatan pupuk booster dengan bahan alami yang tersedia di setiap rumah. Peserta sosialisasi tampak antusias dalam mendengarkan apa yang disampaikan. Secara keseluruhan, pengabdian ini mampu meningkatkan tingkat pemahaman dan kemampuan mitra terkait pembuatan pupuk booster hingga 92%. Hasil ini menunjukkan bahwa minat masyarakat terhadap pupuk booster sangat tinggi. Kedepannya, masyarakat dapat lebih mampu secara mandiri memanfaatkan berbagai bahan alami dari lingkungan sekitar sebagai bahan pembuatan pupuk organik yang dapat meningkatkan hasil pertaniannya.

Abstract

The conventional steam-based sterilization of crude palm oil (CPO) in Indonesia is known to be energy- and water-intensive, as well as time-consuming. This necessitates more efficient and sustainable alternatives, such as microwave oven heating. While microwave applications in CPO sterilization have been explored as a more efficient and sustainable alternative, existing studies often lack comprehensive optimization and a systematic investigation of key process parameters. This study aimed to optimize fresh fruit bunch (FFB) sterilization using a microwave oven to identify optimal operating parameters for maximizing oil extraction yield and minimizing Free Fatty Acid (FFA) content. The Central Composite Design (CCD) within Response Surface Methodology (RSM) was employed as a statistical technique to model the process and ensure the validity of the results. Three independent variables were investigated: sterilization time (6–20 min), fruit mass (396–1104 g), and fruit maturity level (ripe and over-ripe), resulting in twenty-six experimental combinations. Optimal conditions for maximum yield and lowest FFA were determined at 6 min sterilization time and 550 g fruit mass for both maturity levels. Conversely, suboptimal conditions at 11.5 min and 150 g fruit mass for both maturity levels resulted in the lowest yield and highest FFA. This research provides crucial insights for developing an optimized microwave sterilization technique, enhancing palm oil processing efficiency and product quality. The findings underscore the potential for a scalable, low-energy sterilization method that could significantly reduce the environmental footprint of CPO production, instilling optimism about the positive impact of this research.

Abstract

Boron is a micronutrient that plays an important role in plant growth and development. This research aims to determine the response of several varieties to the application of different doses of boron fertilizer and to obtain the best dose for each variety. The experiment was arranged in a randomized block design with a two-factor factorial pattern with two replications. The first factor is three varieties of green beans (Kutilang, Vima 2, Sampoeng) and the second is five levels of boron fertilization doses (0 kg ha-1, 1,5 kg ha-1, 3,0 kg ha-1, 4,5 kg ha-1, 6,0 kg ha-1). The variables observed are growth, yield and yield components variables. Data were analyzed using analysis of variance and Duncan's test, each at the 5% level. The optimum dose for each variety was obtained through second order (quadratic) regression analysis. The results show that there are differences in the response between the three varieties to boron fertilizer in the variable seed weight per plant. The influence of varieties can be seen independently on all variables, the influence of boron fertilizer has an independent influence on all variables except the number of primary branches. The optimum dose of boron for the kutilang variety is 2.39 kg ha-1, the Vima 2 variety is 3.36 kg ha-1, and Sampoeng, 3.19 kg ha-1.
