Solok Regency is famous for its high quality rice. Nagari Dilam, Bukit Sundi District, as a village with a large rice commodity in Solok Regency, most of the residents have a livelihood as rice farmers. To obtain good yields, the material that is needed during the planting process is fertilizer. However, fertilizer problems almost always appear every year in this area. In the last 2 years, farmers have complained due to these problems, including the price of commercial inorganic fertilizers (Urea, SP36, KCl, ZA) which tends to increase. In addition, without realizing it, the intensive use of commercial inorganic fertilizers can cause a decrease in soil fertility and soil organic matter decreases. The idea of using wasted straw came up as a way to solve these problem to prodice orgnic fertilizer. A training in preparation of organic fertilizer from wasted straw has been conducted in Nagari Dilam. The produced organic fertilizer has been characterized for N, P,K containing subtance. The fertilizer contains 0.030%, 4.563% and 1.369% of N, P, and K respectively. \u0000 \u0000Keywords Organic, Fertilizer, Wasted Straw, Rice","PeriodicalId":148835,"journal":{"name":"Pelita Eksakta","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133830171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A driving force for the development of tourist villages is called groups Tourism Awareness (POKDARWIS). A frequently reported problem for tourist areas is the increasing volume of waste originating from tourists. One solution to overcome the problem of organic waste, especially food waste is to turn the waste into an ecoenzyme. Ecoenzyme is an organic solution that produced from simple fermentation of fresh vegetables and fruit peel waste, brown sugar and water. Ecoenzyme could be used to hand sanitizer and disinfectant, that one of the most needed products during this COVID-19 pandemic. Ecoenzyme also has the potential to become organic fertilizer solutions for agriculture so as to reduce the use of chemical fertilizers, vegetable and fruit yields better and the environment is not polluted. Ecoenzymes can help the maintenance sanitation and control of lake water quality. So that ecoenzyme has the potential to save expenses and earn additional income public. Through the use of biotechnology ecoenzyme is expected to be a preventive effort for the development of tourist villages through good and useful waste management. Based on the feedback was given, in general, people feel very satisfied and know that organic waste can great benefit to life.","PeriodicalId":148835,"journal":{"name":"Pelita Eksakta","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129690145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the area, natural resources are quite abundant such as catches of fish, squid, shellfish and so on, but they are not utilized optimally because the catch is only sold in fresh form. Whereas in addition to being sold in fresh form, it can also be processed into products so that the selling value increases. This is due to the slow access to incoming information in the surrounding area, due to the low level of education of local residents. Apart from that, people are left behind in the development of technology and important information that has been and is being developed. Such as important information regarding simple appropriate technology that can be applied to produce fishery products, this is because there have never been socialization activities for processing fishery products and other foods. The purpose of this activity is that the people of Saoka village are able to know about the processing of fishery products, so that later the community will be able to apply it in daily life, or make it a business area on a household scale. The method of implementation is by means of lectures and discussions with participants on how to make fish balls, fish nuggets, fish floss, seaweed meatballs and seaweed syrup. The result of the activities that have been carried out is that the people of Saoka village, Maladum district mes, Sorong city, West Papua, responded very well and enthusiastically. This is indicated by the increase in the value of the pre-test and post-test regarding the processing procedures for fishery products.

However, this condition has an impact on their income economy. People can return to their activities to meet their needs by implementing a new normal life through health protocols. However, information and knowledge on how to maintain body immunity and the implementation of a new normal life are still limited. Therefore, it is necessary to disseminate information about the importance of body immunity during this pandemic. One of the areas affected by this pandemic is Bungus Barat Village, Bungus Teluk Kabung District. To answer the problems that arise in this area, it is necessary to carry out service activities that aim to provide information to the community, especially mothers who are the spearheads of families who are members of the association of PKK women in West Bungus Village on how to increase and maintain immunity during the pandemic. This increase in immunity includes lifestyle and diet that must be followed in the new normal life. Participants in this service activity include representatives of PKK women in West Bungus Village. The activity is in the form of implementation which is divided into two stages, namely guided activities, and independent activities. In the guided activities, interactive and practical counseling methods are used. Meanwhile, in independent activities, the target is to carry out the practice of making spice drinks and VCO in groups again. The results of the activity showed an increase in target knowledge about kitchen spices and coconut into VCO and nutritious spice drinks. The target community, namely PKK women, is also interested in consuming and producing their own VCO and spice drinks that have been made. In addition, from this activity, the community gained a good understanding of what to do during this pandemic, not only in complying with health protocols but also in regulating lifestyle and eating patterns. \u0000","PeriodicalId":148835,"journal":{"name":"Pelita Eksakta","volume":"577 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115895706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
