Abstract

Daun binahong (Anredera cordifolia) telah lama dikenal memiliki berbagai manfaat kesehatan, terutama dalam pengobatan tradisional. Daun ini mengandung senyawa bioaktif seperti flavonoid, saponin, dan polifenol yang berfungsi sebagai anti mikroba, antioksidan, dan antiinflamasi. Ekstraksi adalah langkah penting yang harus dilakukan untuk memaksimalkan manfaat senyawa bioaktif yang terkandung dalam daun binahong. Penelitian ini bertujuan untuk mengoptimalkan proses ekstraksi ultrasonikasi daun binahong menggunakan metode central composite design (CCD) pada response surface methodology (RSM). Faktor yang diuji meliputi daya ultrasonikasi (350–832,84 W) dan waktu ekstraksi (5–35,17 menit). Hasil penelitian menunjukkan bahwa kombinasi daya 750 W dan waktu ekstraksi 30 menit menghasilkan yield tertinggi sebesar 7,6%. Analisis varians (ANOVA) mengungkapkan bahwa daya dan waktu ekstraksi berpengaruh signifikan terhadap yield ekstrak dengan nilai p < 0,05, serta interaksi antara kedua faktor ini juga signifikan. Model regresi polinomial yang dihasilkan memiliki koefisien determinasi R2 sebesar 0,97, menunjukkan kecocokan yang sangat baik antara prediksi dan data eksperimen. Meskipun hasil penelitian ini menjanjikan, aplikasi skala industri memerlukan penelitian lebih lanjut untuk mengatasi potensi degradasi bahan dan faktor teknis lainnya. Penelitian ini memberikan kontribusi pada pengembangan proses ekstraksi ultrasonikasi yang efisien dalam meningkatkan yield bioaktif dari daun binahong.

Abstract

The increasing global energy demand and environmental concerns necessitate the development of alternative energy sources. Durian peel, an abundant agricultural waste in Indonesia, presents significant potential for bio-briquette production due to its high cellulose and lignin content. This study investigates the effect of carbonization temperature on the quality of durian peel-based bio-briquettes. Carbonization was conducted at 300°C, 400°C, 500°C, and 600°C, with proximate analysis and calorific value determination performed according to SNI 01-6235-2000 standards. The results demonstrate that higher carbonization temperatures reduce moisture and volatile matter while increasing fixed carbon and calorific value. At 500°C, the bio-briquettes exhibited optimal properties, including moisture content (7.47%), volatile matter (13.54%), and a calorific value exceeding 5000 cal/g, meeting the SNI standard. However, ash content at this temperature (9.33%) slightly exceeded the standard (≤8%), highlighting a trade-off between energy efficiency and residual minerals. This study concludes that 500°C is the optimal carbonization temperature for producing high-quality bio-briquettes from durian peel, balancing energy output and combustion efficiency. Further optimization of the process is recommended to enhance fixed carbon content and minimize ash. These findings contribute to sustainable energy practices by transforming agricultural waste into a renewable energy resource, addressing both waste management and energy challenges.

Abstract

West Sumatra has a high potential of coconut resources with most of it being processed for copra products. The pandemic situation in recent years has caused the price of copra products to fluctuate, so an alternative coconut processing is needed. Virgin Coconut Oil (VCO) is an alternative coconut product that can increase economic value of coconut and is needed as a supplement that can strengthen the body's immune system during the Covid-19 pandemic. One of the efforts to train the community to be able to process coconut into VCO is to conduct training activities that are directly located in the coconut farmer cluster, which is carried out in Sungai Sirah Village, South Coast District, West Sumatra. This community service activity aims to increase the competence of farmers in the village so that they can process the coconut produced into VCO, hence help their economy when the price of copra drops. The stages of the activity start from socialization, presentation on production process, and continued with demonstrating how to make VCO. Participants were divided into several small groups where they could immediately practice how to make this VCO with the correct fermentation steps. After the manufacturing process is well understood, the next step was training of how to do packaging and marketing. Farmers were trained on how to package products in order to get good quality product and then trained to sell VCO through online shop such as Facebook, Instagram, Tokopedia, etc. This activity helps add more insight in terms of processing and marketing, in which participants increase their knowledge and competence to form the basis for entrepreneurship of coconut processed products.

Abstract

The leaves of Anredera cordifolia, or binahong, are one of the herbal plants with a high potential for antioxidants and have been reported to be rich in flavonoids. This study aimed to determine the best operating conditions in the ultrasonication extraction method from binahong leaves extract on the yield obtained. Experiments were conducted into how extraction conditions affected the ultrasonication extraction of binahong leaves. Different extraction parameters, such as ethanol concentration (20–100%), time (10–40 min), temperature (30–70 C), and yield impacts, were used to extract powdered dried binahong leaves. The results showed all extraction parameters to have significant effects on yield obtained. The maximum yield of extract from binahong leaves was obtained at 60 ml of ethanol concentration, 20 minutes of extraction time, and 50°C ultrasonication bath temperature. Thus, it can be concluded that the ultrasonication process is a good way to obtain a better yield of simplicia of binahong leaves extract as a therapeutic herbal in the future.

Abstract

Plastic waste is a global environmental issue due to its non-biodegradable nature. One potential solution is the development of eco-friendly bioplastics derived from natural materials. This study aims to develop bioplastics based on sago starch with the addition of microfibrillated cellulose (MFC) from empty palm oil fruit bunches as a reinforcing filler to enhance mechanical properties. Additionally, plasticizers such as glycerol and sorbitol were added to improve the elasticity of the bioplastic. The plasticizer concentrations used were 1, 5, 10, 20, and 30% w/w. Characterization was conducted through mechanical property tests (tensile strength, elastic modulus, and elongation percentage), morphological analysis using SEM, and structural analysis with Fourier Transform Infrared Spectroscopy (FTIR spectroscopy). The results showed that the addition of 5% glycerol produced a tensile strength of 26.39 MPa with an elongation of 1.2%, while 20% sorbitol yielded a tensile strength of 25.35 MPa with an elongation of 6.2%. Based on the Indonesian National Standard (SNI) for plastics, the combination of sago starch and MFC with 20% sorbitol provided the best mechanical properties, with a tensile strength of 25.35 MPa and an elongation percentage of 5.6%. In conclusion, sago starch-based bioplastic with MFC from oil palm empty fruit bunches has the potential to serve as an environmentally friendly alternative to synthetic plastics.

Abstract

Decanter merupakan alat yang digunakan untuk mengutip kembali kandungan minyak yang masih terdapat di dalam sludge dengan metode sentrifugal. Jika decanter tidak bekerja dengan efisien, maka kadar air, minyak, dan solid akan meningkat, yang dapat merugikan pihak pabrik. Penelitian ini bertujuan untuk mengevaluasi pengaruh laju alir umpan terhadap persentase kehilangan minyak di water phase dan solid phase pada decanter. Adapun variasi laju alir umpan yang digunakan adalah 21, 22, dan 23 ton/jam. Penelitian ini dilakukan dengan memvariasikan laju alir umpan ke dalam decanter pada 21, 22, dan 23 ton/jam. Evaluasi dilakukan untuk menentukan losses pada water phase dan solid phase dari keluaran decanter. Hasil penelitian menunjukkan bahwa losses pada solid phase tertinggi terjadi pada laju umpan 23 ton/jam dengan rata-rata selama seminggu sebesar 3,38%, sedangkan losses terendah terjadi pada laju umpan 21 ton/jam dengan rata-rata selama seminggu sebesar 3,27%. Ini menunjukkan bahwa laju umpan 21 ton/jam memiliki pemisahan antara minyak dan solid yang lebih efisien dibandingkan dengan laju umpan 23 ton/jam. Pada water phase, losses tertinggi terjadi pada laju umpan 23 ton/jam dengan rata-rata selama seminggu sebesar 0,81%, sedangkan losses terendah terjadi pada laju umpan 21 ton/jam dengan rata-rata selama seminggu sebesar 0,80%. Hasil ini sejalan dengan losses pada solid phase decanter.
