Abstract

Penelitian yang dilakukan bertujuan untuk merancang dan mengimplementasikan sistem instrumentasi pada sarang lebah yang diberi nama MOTIVE untuk budidaya lebah Tetragonula laeviceps. Tujuan implementasi ini adalah untuk mengoptimalkan produksi propolis berdasarkan data dari sistem instrumentasi menuju sistem pertanian presisi berbasis data. Bahasa program yang digunakan sebagai antarmuka pada Arduino dan Raspberry Pi adalah Arduino dan Python. Parameter yang diukur oleh sensor pada sarang MOTIVE adalah temperatur, kelembapan, massa sarang MOTIVE serta total lebah keluar masuk sarang yang diperbarui setiap 15 dan 30 menit sekali. Variasi penelitian berupa intensitas cahaya yang diimplementasikan pada koloni dalam sarang bambu, sarang MOTIVE berbahan kayu, dan sarang MOTIVE berbahan akrilik. Propolis yang dihasilkan oleh lebah dipanen untuk dianalisis kandungan flavonoid berbasis ekivalen kuersetin. Data yang diperoleh menunjukkan bahwa produktivitas propolis yang dihasilkan oleh lebah pada sarang MOTIVE sebanyak 2-2,4 g/sarang/minggu. Nilai kandungan flavonoid tertinggi pada ekstrak propolis diperoleh dari propolis yang dihasilkan oleh lebah pada sarang MOTIVE kayu sebanyak 14,3 mg QE/gram. Sistem instrumentasi terbukti berhasil melakukan perekaman data secara simultan dan tidak mengganggu aktivitas lebah. Berdasarkan parameter yang diukur, konversi resin menjadi propolis secara optimal terjadi pada sarang dengan variansi temperatur dan kelembapan yang kecil, serta intensitas cahaya pada sarang terbukti berpengaruh pada produksi propolis.

Abstract

Citronella oil, which is also known as Java citronella oil, is typically obtained from the leaves of Cymbopogon winterianus Jowitt and has been widely used as an antiseptic, fragrance, flavor, and many other applications. However, systematic studies on the factors affecting the yield and composition of citronella oil are limited. Hence, this study was carried out to investigate the influence of water stress (low to high) and plant age (0.5 to 5 years) on the yield and composition of citronella oil. Citronella leaves were dried at room temperature (26–30 °C) with a relative humidity of 62–74% for 3 days before the citronella oil was extracted using a steam distillation unit. Introducing a high water stress condition to the plants increased the yield from 0.80% (control) to 1.4% (high water stress) dry weight. The geraniol content slightly increased from 15% to 17%, whereas the citronellal content considerably increased from 31% to 44% when the plants were subjected to high water stress in comparison to the control. The oil yield increased with plant age before it reached its plateau at 3.5% dry weight at age 4 years. However, the composition of citronella oil did not significantly vary with plant age.

Abstract

Lemon peel and leaf  as well as lower grade of lemon contain a considerable amount of flavonoid which can be extracted to produce a valuable product. The presence of pectin in lemon hinders the extraction of flavonoid compound. This research was conducted to examine the effect of pectin biodegradation of lemon leaf, peel, and lower grade fruit using solid-state fermentation towards the yield of pectin, crude flavonoid, and total flavonoid content. Fermentation was carried out with the help of Aspergillus niger at 30℃ for 3, 5, 7, and 9 days of cultivation time. Pectin was extracted from the fermentation broth using citric acid. Crude flavonoid was extracted using maceration and stirred about 500 rpm at 50℃ for 40 minutes. Total flavonoid content was analyzed using a spectrophotometer. The optimum cultivation time of Aspergillus niger with leaf and peel was 9 days with a pectin yield from lemon leaf was 0.43% dry weight and the pectin yield from lemon peel was 0.04% dry weight. As for the lower grade fruit, a cultivation time for 7 days showed an optimal result with a pectin yield of 0.08% dry weight. The total flavonoid content in the leaf increased up to 94.3% (1.06 mg of the quercetin equivalents per g of substrate) whereas the total flavonoid content in the peel and lower grade fruit increased up to 42% (0.12 mg of the quercetin equivalents per g of substrate) and 48% (0.021 mg of the quercetin equivalents per g of substrate), respectively. These results highlighted the potential valorization of Citrus limon L. as an alternative source for producing flavonoid in food and pharmaceutical industry.

Abstract

Banyuasin Regency, located in the province of South Sumatra, has the largest area of rubber plantations in Indonesia, with huge potential as biodiesel feedstock, and generates income for rubber planters through the exploitation of the seeds. This study focuses on the value chain of the exploitation of seeds for biodiesel and its economic benefits to the planters using the Hayami method. The snowball and stratified random sampling methods were used to determine the pricing of the seeds. The value chain actors include the rubber planters, the crumb rubber processing and marketing unit, the biodiesel processing unit, and the consumers, which operate through the market governance structure. The findings indicate that rubber seed processing generates an added value of IDR 4,937/kg, with a value-added ratio of 64%, classifying it as a high-value commodity. Furthermore, integrating rubber seed value chain activities has the potential to increase farmers’ annual income by IDR 3,850,000, contributing to financial sustainability. A techno-economic analysis confirms the feasibility of intermediate-scale biodiesel production in Banyuasin Regency, with a benefit-cost ratio of 1.35, demonstrating its potential to create substantial economic value from rubber seeds. These findings highlight a strategic opportunity for the crumb rubber processing and marketing unit in the Banyuasin Regency to enhance its role within the supply chain while improving farmer profitability. By optimizing value chain efficiency and ensuring market stability, rubber seed-based biodiesel production can contribute to economic growth, rural development, and renewable energy advancement in Indonesia.
