Abstract

Abstract.  Anise seeds can be processed into essential oils by steam distillation and solvent extraction. This research aims to produce a high oil yield by determining the optimum conditions of extraction, extracting anise seeds according to optimum conditions, producing anise oil with good quality based on 90% alcohol solubility analysis, analyzing the acid number, and conducting GC-MS analysis. The Activity Method was carried out by determining the optimum conditions of extraction on the effect of the variation in the ratio between anise seed powder and petroleum ether. Furthermore, based on optimal conditions, extraction was carried out at a temperature of 60°C, 5 hours with 5 repetitions. The results of essential oils were analyzed including solubility analysis, oil acid number, and GC-MS. The optimal extraction conditions were obtained at the ratio of anise seeds and petroleum ether 1:12.5 with an average oil yield of 4.72%. The results of the analysis showed that anise oil had good quality based on the oil solubility in 90% alcohol with a 1:7 ratio. The acid number of anise seed oil was obtained at 1.14444. GC-MS analysis showed that anise seed oil contained estragol, anethole, limonene, fenchone, and anis ketone.Keywords:Anise seeds, essential oil, soxhlet, GC-MS

Abstract

Abstrak: Permasalahan serius bagi peternak adalah rendahnya pengetahuan dan keterampilan dalam berinovasi menghasilkan pakan ternak alternatif. Kebutuhan pakan dengan biaya lebih dari 70% dari total biaya produksi, berdampak pada keberlanjutan usaha peternak mandiri. Tujuan kegiatan adalah untuk mengetahui pengaruh proses edukasi terhadap peningkatan pengetahuan dan keterampilan bagi peternak dalam pembuatan pakan ternak alternatif berbahan limbah organik melalui biokonversi larva Black Soldier Fly (BSF) atau maggot. Metode kegiatan melalui proses edukasi bagi peternak mandiri pada salah satu wilayah di kelurahan Bontonompo yang berjumlah 25 orang. Pengambilan data dilakukan melalui lembar kusioner yang terdiri dari tujuh pertanyaan pengetahuan dan empat pertanyaan keterampilan yang diambil sebelum (pretest) dan setelah (posttest) pelaksanaan penyuluhan dan pelatihan. Hasil kegiatan memperlihatkan model edukasi PDEA (planning, doing, assessing, evaluating) terbukti efektif dalam meningkatkan pengetahuan peserta berkisar (76-90%) dan keterampilan sekitar (80-96%), serta memberikan dampak yang signifikan terhadap pengurangan biaya pakan bagi peternak hingga 25-40%. Penerapan model edukasi PDEA dapat menjadi acuan pengolahan limbah organik menjadi pakan maggot.Abstract: A serious problem for farmers is their lack of knowledge and skills in innovating alternative animal feed. Feed costs account for more than 70% of total production costs, impacting the sustainability of independent livestock farmers' businesses. The objective of this activity is to determine the effect of the educational process on improving farmers' knowledge and skills in producing alternative animal feed from organic waste through the bioconversion of Black Soldier Fly (BSF) larvae or maggots. The activity method involved an educational process for independent farmers in one area in the Bontonompo sub-district, consisting of 25 people. Data collection was carried out using a questionnaire consisting of seven knowledge questions and four skill questions, which were administered before (pre-test) and after (post-test) the implementation of the counseling and training. The results of the activity showed that the PDEA (planning, doing, assessing, evaluating) education model was proven to be effective in increasing participants' knowledge by 76-90% and skills by 80-96%, as well as having a significant impact on reducing feed costs for farmers by 25-40%. The application of the PDEA education model can be a reference for processing organic waste into maggot feed.

Abstract

The research aims to examine the potential of tofu industry wastewater (whey) to become a product of economic value for society. The research was carried out using a survey method to identify whey wastewater production in the tofu industry and continued with experiments on the characterization and processing of whey wastewater on a laboratory scale. Whey wastewater is processed using a honeycomb anaerobic biodigester with a capacity of 120 liters. The research stage involves making a starter from a mixture of cow dung, water, and whey wastewater (3:1:1) which is fermented for 21 days. After the starter shows that the growth of microorganisms (MO) is in the log, it is continued with one liter of whey wastewater every day. The results obtained show that whey wastewater contains protein 0,9482%,, carbohydrate0,4473% and fat0,2186% which is a substrate for MO. Anaerobic processing of whey wastewater using a honeycomb anaerobic biodigester produces biogas with a blue flame (methane gas > 45%). Then the Honeycomb biodigester slurry contains urea compounds which are fertilizer ingredients. Therefore, the potential for processing whey wastewater can produce renewable energy (biogas), liquid and solid organic fertilizer containing vitamin E and thiophospatoethyl aminohexylurea (N and P elements) as well as being a solution for handling environmental pollution, thereby creating a sustainable.
