Kepok bananas are a fruit with a very fast ripening process when stored at room temperature.In this study, kepok bananas were packed with active packaging made from palm kernel shell activated charcoal, which was activated by 20% phosphoric acid in sachets to slow down the ripening process. This study was aimed to analyse the tendency of changes in the physical and chemical properties of kepok banana with active packaging made from palm kernel shell activated charcoal stored at room temperature and to determine the best active packaging that can extend the shelf life of kepok bananas. The old and ready-to-harvest kepok bananas were weighed as much as 350 g and packed with LDPE in the middle as primary packaging and foam net as secondary packaging. The kepok bananas packaging was added with 5 or 10 g of activated charcoal in the sachets packed with LDPE or tea bags. Kepok bananas with active packages were stored at 28 ± 2 o C for 16 days and observed every two days in the form of weight loss, edible parts, moisture content, total dissolved solids, reducing sugar content, and total dissolved acid. The data were analyzed by regression order 2, order 3 or order 4 adjusted to the R 2 value close to 1. The results showed that during storage the weight loss of kepok banana increased quadratically. The edible part changes followed the order 4 pattern, while the moisture content, total dissolved solids, reducing sugar content, and total dissolved acid followed the order 3 pattern. The best active packaging to extend the shelf life of kepok bananas was kepok bananas with 10 g of active charcoal in LDPE packaging.

Nagara bean/ catjang (Vigna unguiculata spp. Cylindrica) is a subspecies of cowpea which is widely cultivated in freshwater swamplands of Daha Utara and Daha Selatan sub-districts, Hulu Sungai Selatan Regency. Nagara bean is a plant native to South Kalimantan, but its utilization is still very low compared to other cowpeas. The aims of this study were to analyze the chemical and physical characteristics of Nagara bean in processed food compared to those of soybeans; and to analyze the development potential of Nagara bean in processed food. The methods were the production of catjang flour from skinless Nagara beans; the production of catjang flour by roasting Nagara beans; the substitution of Nagara beans with coagulated and fermented soybeans. The results showed that the flour from skinless Nagara beans contained protein (24.16%) and carbohydrate (61.62%), while the flour from roasted Nagara beans contained protein (18.42%) and carbohydrate (69.33%). When compared to soybeans, papan and arabian beans, the two types of Nagara bean, could be coagulated with a higher water content and lower protein content. When Nagara beans were fermented, the water and protein contents of fermented beans were higher than those of soybeans. It can be concluded that Nagara beans could be used in processed foods chemically. Nagara beans however absorbed water easily, so they smelled sour and unpleasant and the texture became soft.

Granules and gels of tapioca will be easily fragile and broken when heated. This study aimed to investigate the characteristics of tapioca cross-linked acylation substituted Nagara bean flour. The method used is the native tapioca cross-linked with Sodium Tripolyphosphat 2 and 5 % and acylated with stearic acid 2 and 4 % under alkaline conditions. Cross-link tapioca then substituted with Nagara beans flour in the ratio 50:50. The highest degree of substitution found in tapioca starch modified with 5 % STPP and 2 % stearic acid, i.e 0.14. The only maximum viscosity of tapioca starch of cross-linked acylation STPP 5 % and stearic acid 2% higher than native tapioca (5220 cP). The breakdown viscosity lower than native tapioca (3651 cP), final and setback viscosity higher than native tapioca (3023 cP and 1454 cP), and pasting temperature higher than native tapioca starch (67.65 °C). When added with Nagara beans flour then the maximum, breakdown, final, and setback viscosity is descended and pasting temperature is 78.5 oC. It is concluded that the granule of tapioca crosslink STTP 5 % and acylation stearic acid 2 % and substituted with Nagara beans flour in the ratio 50:50 is not easily fragile and broken.

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.
