Abstract

Small Rice mill or called “Selipan” in Indonesian, is a series of rice mill machines with various engine capacities, generally found in agricultural production centers. Rice mills require relatively large investment costs for producers in the production area. A feasibility study on the rice mill business at Selipan Riyanto is needed to be a reference for pioneering similar businesses. A business feasibility study is a comprehensive assessment to assess the success of a business. Rice mills are industrial facilities designed to convert paddy into milled rice. The milling process includes a series of operations, including rice cleaning, hulling, polishing, and packaging. This study aimed to evaluate financial feasibility of Selipan Riyanto based on NPV (Net Present Value), PI (Profitability Index), IRR (Internal Rate of Return), and PP (Payback Period). The study's results obtained a value, NPV (Net Present Value) of Rp. 266.613.794, PI (Profitability Index) of 2.54, IRR (Internal Rate of Return) of 59%, and PP (Payback Period) of 1.46 years.

Abstract

Crude palm oil (CPO) is characterized by high carotenoid content, dissolving in the oil system and causing a difficult extraction process. To overcome this problem, transesterification of CPO with ethanol was performed to improve the carotenoid extractability using sodium hydroxide as a catalyst. Therefore, this study aimed to investigate the effect of ethanolysis parameters on the carotenoid and fatty acid ethyl ester (FAEE) content of CPO. FAEE content was quantified by thin-layer chromatography and total carotenoid content (TCC) was determined through a UV-Vis spectrophotometer. Reaction time (15-150 min), catalyst concentration (0.65-3.25%), reaction temperature (3070 ℃), and stirring speed (500-2000 rpm) were determined by one factor at a time (OFAT) design. The results showed that ethanolysis time and temperature did not affect TCC along the study range, while ethanolysis time of 45 minutes and temperature of 70 ℃ increased FAEE content. Additionally, catalyst concentration of 1.95% and stirring speed at 2000 rpm increased TCC and FAEE. The best ethanolysis parameters were obtained at 45 minutes, the temperature of 50 ℃, catalyst concentration of 1.3%, and stirring speed of 2000 rpm, yielding FAEE 1358±16 ppm and TCC 99.9±0.2%. This showed that ethanolysis produced high FAEE content and improved carotenoids in the oil system.

Abstract

DOI of original article: https://doi.org/10.22146/agritech.81499Authors Correction:The authors regret a typographical error in the ABSTARCT page 41. It was written as 'yielding FAEE 1358±16 ppm and TCC 99.9±0.2%'. It should correctly read 'yielding FAEE 99.9±0.2% and TCC 1358±16 ppm'.

Abstract

Gluten-free noodles are increasingly important as alternatives to wheat-based products for consumers with gluten intolerance and for the diversification of functional foods. This study aimed to characterize the physicochemical and functional properties of purple corn flour and evaluate its application in gluten-free noodle development using modified cassava flour (mocaf). Purple corn flour was produced by drying and milling and formulated into noodles at different purple corn flour:mocaf ratios (20:80–60:40). Proximate composition, functional properties, color, and RVA pasting behavior were analyzed, while noodle quality was evaluated through cooking properties, texture profile, anthocyanin content, and antioxidant activity. Purple corn flour showed a peak viscosity of approximately 1750 cP and moderate setback viscosity (342 cP). Increasing purple corn flour significantly increased anthocyanin content (0.75–5.21 mg/L) and antioxidant activity (33.99–49.21% inhibition), while formulation ratio affected cooking time, cooking loss (1.54–4.66%), and hardness (53.59–132.47 g). These results indicate that purple corn flour is a promising functional ingredient for gluten-free noodles with acceptable technological quality and enhanced bioactive properties.

Abstract

Indonesia merupakan penghasil nipah terbesar, kandungan gula nira nipah cukup tinggi, namun pemanfaatannya masih terbatas. Selama ini, nira nipah hanya dimanfaatkan untuk pembuatan gula nipah dengan nilai ekonomi yang terbatas, padahal kandungan gulanya berpotensi besar untuk diolah menjadi bioetanol sebagai energi terbarukan. Program pengabdian kepada masyarakat meliputi studi kualitas bahan baku nira nipah yang bersumber dari daerah sentra produksi nipah, yakni Desa Pedasong dan Nusadadi, serta kegiatan pelatihan alih teknologi produksi bioetanol. Kegiatan pelatihan teknis pembuatan bioetanol dengan fermentor menggunakan metode Simultaneous Saccharification and Fermentation (SSF) diikuti 25 peserta. Hasil analisis kualitas bahan baku yakni nira nipah Desa Pedasong dan Desa Nusadadi memiliki kesamaan kadar brix sebesar 15,09 ± 0,49% dan 15,04 ± 0,44%, pH senilai 6,86 ± 0,07 dan 6,87 ± 0,07, serta kadar etanol senilai 80,40 ± 0,63% dan 80,53 ± 0,71%, berurutan. Namun memiliki kandungan glukosa yang berbeda, yakni nira nipah Desa Pedasong (4,54 ± 0,01%) lebih tinggi dibanding Desa Nusadadi (4,19 ± 0,01%). Serta menghasilkan yield bioetanol yang berbeda, yakni Desa Pedasong sebesar 6,04 ± 0,29% dan Desa Nusadadi 5,04 ± 0,31%. Selain itu, hasil pelatihan menunjukkan adanya peningkatan signifikan pada pengetahuan peserta dengan rata-rata skor pre-test 59,60±13,38 dan post-test 83,60±14,11 (p=0,000). Analisis lebih lanjut menemukan bahwa jenis kelamin berpengaruh pada skor post-test di mana perempuan lebih tinggi dibanding laki-laki, sedangkan profesi berpengaruh pada skor akhir dengan hasil ibu rumah tangga lebih tinggi dibanding non-IRT. Namun, tingkat pendidikan tidak berpengaruh terhadap peningkatan maupun skor akhir. Hasil analisis studi bahan baku menunjukkan bahwa ketersediaan bahan konversi (kandungan glukosa) yang lebih tinggi dapat meningkatkan yield bioetanol. Selain itu, hasil pelatihan menunjukkan bahwa alih teknologi bioetanol dari nira nipah efektif sebagai model penguatan ekonomi masyarakat berbasis energi terbarukan.
