Abstract

Pewarna alami memiliki kelemahan berupa intensitas dan stabilitasnya yang rendah. Klorofil sebagai sumber pewarna hijau alami memiliki kelebihan yang tidak dimiliki pewarna sintetis. Selain lebih aman, klorofil dapat berfungsi sebagai antioksidan yang dapat memberikan beberapa aktivitas farmakologi. Identifikasi dan kuantifikasi klorofil pada berbagai tumbuhan hijau telah banyak dilaporkan, namun masih terbatas yang memberikan rekomendasi mengenai jenis bahan apa yang lebih potensial untuk dimanfaatkan sebagai sumber klorofil. Penelitian ini bertujuan membandingkan kekuatan (intensitas) warna ekstrak dan stabilitasnya dari empat jenis tumbuhan yang potensial dan umum digunakan secara tradisional, yaitu daun pandan (Pandanus amaryllifolius), daun suji (Pleomele angustifolia), daun katuk (Sauropus androgynus), dan daun kelor (Moringa oleifera). Intensitas dan stabilitas larutan ekstrak warna tumbuhan yang dipilih dinilai secara objektif dengan mengukur nilai absorbansinya pada panjang gelombang 500 nm menggunakan UV-Vis Spektrofotometer dan komposisi RGB melalui penilaian citra digital, serta secara subjektif melalui pengujian hedonik. Stabilitas warna diuji selama tujuh hari penyimpanan dengan perlakuan tambahan berupa penambahan dan tanpa penambahan NaHCO3. Dari aspek intensitas warna, ekstrak suji menampilkan kriteria yang lebih baik dengan menghasilkan nilai absorbansi, komposisi RGB, dan kesukaan yang lebih tinggi dibanding ekstrak warna lainnya. Penambahan NaHCO3 pada larutan ekstrak suji dapat meningkatkan intensitas dan juga stabilitas warnanya. Keunggulan ekstrak pandan terdapat pada aspek rasa dan aroma, di mana tidak dimiliki oleh ekstrak suji. Kelemahan ekstrak pandan adalah stabilitasnya yang rendah selama penyimpanan, meskipun telah ditambahkan dengan basa NaHCO3.

Abstract

Organic waste was the potential to contaminate the environment. Hermetia illucens or BSFL were the insects that could decompose waste and produce larvae biomass. It had high efficiency for waste reduction. The kind of substrate could affect the waste reduction performance of BSFL. This study determined the effect of the kind of waste on the effectiveness of reducing waste by Hermetia illucens. The larvae were reared on domestic waste and solid decanter. Each treatment (three replicates per treatment) contained 300 larvae seven days old with a daily food rate of 125 mg/larva/day. After instar fourth and fifth old, the larva was harvested using sterile forceps. The ratio of waste reduction (%WR), Efficiency of conversion of digested feed (ECD), bioconversion rate (BCR), and biomass were calculated in the fourth and fifth instar. The results showed that larvae on domestic waste had a higher waste reduction performance than larvae on the solid decanter. The results showed that larvae could reduce domestic waste to 76.5% and 32.6% on the solid decanter. Larva on domestic wasted showed higher ECD, BCR, and biomass than larvae on the solid decanter. It showed that BSFL had higher waste reduction performance on the domestic waste than on solid decanter. Therefore the kind of waste could affect the waste reduction performance of BSF larvae.

Abstract

Prevention of the COVID-19 virus can be done by regularly washing hands or using hand sanitizer. This step can prevent the COVID-19 virus from sticking to the surface of the skin.. Therefore, the availability of hand washing soap is urgent as an initial step for corona prevention. The availability of hand soap can be provided independently in the community because the liquid laundry soap can be processed with palm oil. It can be an opportunity for the palm oil community to produce and fulfill the needs community. Handling problems by the community in the era of the covid 19 pandemic are related to understanding and insight for preventing Covid 19 from the family environment, one of which is the awareness of washing hands as often as possible using soap. Therefore, knowledge of producing crude palm oil-based liquid soap in communities around oil palm plantations as well as knowledge of the role of palm-based liquid soap for sanitation and entrepreneurial opportunities are good. This community service activity was conducted through counseling and training related to the manufacture of crude palm oil-based liquid soap for the community of oil palm farmers around the Cipta Prima Sejahtera Professional Services Cooperative in Jilatan Village, Tanah Laut Regency. The activity was to provide knowledge about palm oil and liquid soap-based palm oil that are easy to prepare. During the Covid 19 period, hand washing activities are important as a preventive measure, so the availability of liquid soap independently needs to be produced. The evaluation showed that the training participants were very satisfied with this training, gave a very good response regarding the usefulness and sustainability of this community service activity, and hoped that it could be followed up regarding business sustainability.

Abstract

The red traditional South Kalimantan cooking spice indicates that the seasoning has a deep red appearance. Although the habang cooking seasoning has a dark red appearance with the main ingredient red chili, this spice does not have a spicy taste but tends to taste sweet. This study aimed to determine the effect of different packaging and storage temperatures on the spice’s characteristics. This study used RBD method with 2 factors and 2 replications. Factor A is packaging variation and B is storage temperature. These observations included chemical tests, total microorganism tests, and sensory tests. Chemical tests and microorganisms were analyzed by the ANOVA and followed by the DMRT. Sensory test data were analyzed by the Kruskal Wallis and followed by the Post Hoc Test. Determination of the best results used the ranking method weighting. The results showed the characteristics were changed during storage. water content, peroxide number, and total microorganisms were increased in line with fat content and pH decreased. Sensitively, Habang cooking spices decreased in aroma, color, and viscosity during storage. The best Habang cooking seasoning was found in the use of cold temperature aluminum foil packaging on the 4th day of storage with a total parameter value of 8,224 and a total value of 30,195, chemical characteristics in the form of the water content of 31.46±0.02, a fat content of 69.67±0, 81, the pH value is 4.26±0.02, and the peroxide value is 3.15±0.06.

Abstract

Kampung Purun, Palam, Banjarbaru is well-known as the development of creative industries making purun woven products. The products are in the form of various bags, hats, mats and tissue boxes as well as many other various products. The resulting product has a variety of colors, but in the coloring process the craftsmen still use chemical dyes which are not environmentally friendly. Besides that, the product design is still not varied. This service aimed at innovating purun products produced by the villagers of Kampung Purun, especially the Galoeh Bandjar group by redesigning and innovating the dyes used, namely using natural dyes to boost the chances of purun products being able to pass the export curation. Natural dyes were produced from a combination of jengkol skin and sappan wood, with various formulations developed based on previous research results. The best formula used was 12 : 1 : 7 consisting of water : cup : jengkol skin. The jengkol skin used was waste from the Jaring culinary production process. Dyes were made by boiling the two ingredients. Furthermore, the production stages by designing, coloring, determining color composition and evaluating product quality were carried out at the Banjarbaru Government Packaging House. The resulting color was brownish red and ready to be applied to purun products. The results of the curation by the Packaging House stated that the innovative purun product was feasible to be marketed from a quality standpoint. The selling price of the product was set at Rp. 46,000, - with a production cost of Rp. 36,621, - per unit. This means that there is an additional value of IDR 10,379.

Abstract

BSF larvae were the agents capable of breaking down large amounts of organic waste. These larvae were known to reduce organic waste effectively and produced larval biomass. The substrate type was one of the factors that could affect the larvae's performance. This study aimed to determine the effect of the type of substrate or organic waste on the growth and waste reduction performance of larvae. Larvae were reared for ten days on several organic wastes, including food waste, solid decanter, coconut pulp, and sago pulp. The growth rate, bioconversion rate, waste reduction index, and feed conversion ratio were analyzed. The larvae with the best reduction performance were then analyzed for protein and fat on days 7 and 10. The results showed that BSF larvae in food waste showed more growth than in other wastes. BSF larvae in food waste showed a high waste reduction performance, while BSF larvae in solid decanter showed poor waste reduction performance. The BSF larval biomass in food waste contained high levels of protein and fat (38.94 % and 42.86 %, respectively).
