Abstract

Moringa plants have high nutritional content, especially in the leaves, so they have benefits for human health. Various innovations in food processing technology utilize moringa not only as a vegetable but can be processed into various forms of processed food, one of which is dimsum. Dimsum based on moringa leaf flour is a new food product where moringa leaves have a role as fortification to fulfill nutrition in food. Based on the description, this study was conducted to determine the effect of moringa leaf flour substitution (5%, 10%, 15%) on the quality and sensory properties of dim sum. This study used a research design model used was an experimental with a completely randomized design (CRD) of one factor, namely the formulation of moringa leaf flour with 3 replications. The treatment in this study was the substitution of moringa leaf flour and tapioca flour with a formulation of 5%:95% (D132), 10%:90% (D231), and 15:85% (D213). The analysis included organoleptic testing with hedonic tests by 20 untrained panelists and proximate testing. The best sensory test results for 5% moringa leaf flour substitution had a significant effect on the sensory evaluation assessment of appearance 3,73 , flavor 3,45 , aroma 3,68 and texture 3,65. The proximate test results for 5% moringa leaf flour substitution obtained a protein value of 12.69%, fat 1.32%, ash content 1.2%, moisture content 66,11% and carbohydrate 18.68%

Abstract

Pertanian Indonesia menghadapi tantangan berupa keterbatasan air, perubahan iklim, dan tuntutan peningkatan efisiensi produksi. Teknologi fertigasi menjadi salah satu solusi yang mampu meningkatkan pemanfaatan air dan nutrisi secara presisi. Penelitian ini bertujuan merancang dan mengevaluasi kinerja sistem fertigasi otomatis nirdaya berbasis desain lingko yang memanfaatkan gaya gravitasi tanpa kebutuhan energi listrik. Sistem dirancang menggunakan drum penampung berkapasitas 80 L, pipa PVC berbagai ukuran, serta mekanisme pengontrol ketinggian air otomatis. Tanaman uji adalah kangkung darat (Ipomoea reptans), dengan parameter pertumbuhan meliputi tinggi tanaman, panjang batang, panjang helai daun, dan jumlah daun selama periode 32 hari. Hasil penelitian menunjukkan bahwa desain fertigasi nirdaya berbentuk lingko mampu mendistribusikan air dan nutrisi secara relatif merata ke seluruh ring. Rata-rata tinggi tanaman berada pada kisaran 17,9-18,1 cm, panjang batang 12,5-12,8 cm, panjang helai daun 6,5-6,8 cm, serta jumlah daun 9-11 helai. Ring 1 menunjukkan keunggulan pada pembentukan daun, Ring 2 pada pemanjangan batang, sementara Ring 3 memberikan pertumbuhan yang stabil. Variasi antar ring dipengaruhi oleh jarak distribusi, perbedaan tekanan aliran, serta faktor lingkungan seperti intensitas cahaya dan kondisi media tanam. Temuan ini membuktikan bahwa sistem fertigasi otomatis nirdaya berbasis desain lingko efektif, hemat energi, dan berpotensi menjadi teknologi tepat guna untuk pertanian berkelanjutan, khususnya pada daerah dengan keterbatasan akses energi listrik. Pengembangan skala lebih luas dan pengujian pada komoditas lain direkomendasikan untuk meningkatkan potensi penerapannya dalam sistem budidaya modern.

Abstract

Penelitian ini bertujuan untuk merancang, membangun, dan menguji kinerja fermentor berbahan akrilik yang diintegrasikan dengan sistem sirkulasi pompa peristaltik untuk produksi bioetanol dari molase. Fermentor berkapasitas 7 liter dirancang menggunakan material akrilik yang transparan dan mudah difabrikasi. Sistem sirkulasi pompa peristaltik diterapkan untuk menjaga homogenitas substrat, distribusi nutrisi, dan stabilitas suhu selama proses fermentasi berlangsung. Penelitian dilakukan dengan membandingkan dua kondisi operasi, yaitu fermentasi menggunakan sirkulasi dan tanpa sirkulasi, dengan memanfaatkan ragi Saccharomyces cerevisiae. Parameter yang diamati meliputi suhu, pH, penurunan nilai Brix (kadar gula), dan densitas selama fermenasi 5 hari. Hasil penelitian menunjukkan bahwa sistem sirkulasi berhasil mempertahankan suhu yang lebih stabil pada kisaran 30–31°C serta pH yang konstan. Fermentasi dengan sirkulasi juga mempercepat fase eksponensial pertumbuhan ragi, meskipun durasinya lebih singkat akibat konsumsi gula yang lebih cepat. Penurunan nilai Brix pada sistem bersirkulasi lebih signifikan, yang mengindikasikan efisiensi konversi substrat yang lebih baik. Disimpulkan bahwa fermentor akrilik dengan sistem sirkulasi pompa peristaltik efektif dalam meningkatkan homogenitas dan stabilitas kondisi fermentasi. Untuk pengembangan selanjutnya, diperlukan penambahan sistem kontrol otomatis dan optimasi kecepatan sirkulasi guna memaksimalkan produktivitas bioethanol.

Abstract

Drying is an important postharvest process for reducing the moisture content of copra and maintaining its quality during storage. Conventional drying methods that rely on ambient conditions are strongly influenced by weather and temperature fluctuations, resulting in relatively slow and less controlled drying. This study evaluated the performance of a modified hybrid greenhouse dryer for copra drying by comparing its drying conditions with drying under ambient conditions. The experiment was conducted for five hours by monitoring drying temperature, initial and final moisture content, and moisture reduction rate. The results showed that the maximum temperature in the hybrid greenhouse dryer reached 45 °C, while the ambient drying condition reached 40 °C. The moisture content of copra dried using the hybrid system decreased from 65.91% to 11.61%, whereas the ambient-dried sample decreased from 52.51% to 16.88%. The corresponding moisture reduction rates were 10.86 %/h for the hybrid system and 7.13 %/h for ambient drying, indicating a 52.40% higher reduction rate in the hybrid system during the test period. The improved drying performance was associated with the utilization of solar energy through the collector, air circulation using a blower, and the thermal contribution of stone material within the drying system. Although the initial moisture contents differed between the two samples, the results indicate that the hybrid greenhouse dryer provided a more favorable drying condition and greater moisture reduction over the same drying period. Further studies should use uniform initial moisture content, sufficient experimental replications, and additional thermal-efficiency measurements to provide a stronger evaluation of system performance.

Abstract

Handling agricultural machinery and equipment with significant mass requires lifting aids that can enhance efficiency and reduce manual labor. This study aimed to design and test the performance of a lifting crane intended to assist in the lifting and relocation of agricultural machinery. The research involved design, fabrication, and performance testing using incremental loads of 45, 65, 100, 150, 200, 215, and 250 kg. Testing parameters included load mass, lifting time, lifting height, and the structural condition of the crane under load. The results showed that the crane measured 208 cm in length, 87 cm in width, and 195 cm in height, utilizing an HGS-B Micro Electric Rope Hoist motor for the lifting system. Lifting time increased from 7.35 seconds at a 45 kg load to 10.90 seconds at a 250 kg load, while lifting height decreased from 140 cm to 128 cm. Although the crane was capable of lifting loads up to 250 kg, structural bending in the legs began to occur within the 215-250 kg load range. Consequently, the recommended maximum operating load is 200 kg. The study concludes that the designed crane has the potential to serve as a lifting and handling aid for agricultural machinery, provided that load limits and structural integrity are taken into account.
