Although not life-threatening, acne can affect a person's quality of life by giving a bad psychological effect in the way a person assesses, perceives and responds to his condition and situation. The aim of this study is to asses the antibacterial activity of the extract and fraction of the macroalgae Euchema cottonii against acne-causing bacteria, namely Propionibacterium acnes and Staphylococcus epidermidis. The extraction method used was maceration, using 96% p.a ethanol as a solvent and fractionation using the ECC method with three solvents with different polarity levels, namely n-hexane, ethylacetate and ethanol. The activity test was carried out using the paper disc and micro dilution method with the comparison antibacterial clindamycin. The results showed that there was no antibacterial activity from either the extract or fraction of macroalgae Euchema cottonii against the bacteria Propionibacterium acnes, but there are activity from the extract and fraction (n-hexane and ethylacetate) against the Staphylococcus epidermidis bacteria with the MBC value at a concentration of 15% and MIC at a concentration of 5% (for the extract and n-hexane fraction), while for the ethylacetate fraction the MIC value was at a concentration of 10%. Therefor, the strength of the antibacterial activity of the extract and fraction of Eucheuma cottoni is in the weak category.","PeriodicalId":276781,"journal":{"name":"Jurnal Agrotek UMMat","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125576183","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}

The source of the pathogenic bacterium P. solanacearum was obtained from samples of wilted rhizomes from community ginger field isolated on NA media. This study was arranged based on a completely randomized design with five replications. The research variables were wilt disease severity, plant height, number of leaves, number of stems, stem diameter & rhizome weight. The results showed that R. solanacearum caused symptoms after an incubation period of 9 days after inoculation. The four CE isolates were able to suppress the symptoms of ginger wilt in the range of 70-80%. The use of CE isolate was also able to improve the growth of ginger, but it has not been followed by an increase in the production of ginger rhizomes. It is suggested that the use of CE as a biofertilizer needs to be increased in the frequency of its application.","PeriodicalId":276781,"journal":{"name":"Jurnal Agrotek UMMat","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115223021","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}

The application of refrigeration machines can also be developed in many other equipment and machines, one of which is in the distillation apparatus. Distillation is a method of separating two substances. A distillation machine using a cooling machine in the condenser will be very helpful, especially for distillation. This study aims to determine the effect of cooling on the performance of the cooling machine. Cooling engine performance coefficient of achievement (COP). Load variations are carried out by adjusting the boiler temperature using a thermostat. In this study, data on the temperature and pressure of the refrigerant flowing in the refrigeration system were taken at four points, namely before entering the compressor, before entering the capillary tube and before entering the evaporator . In this study also used four variations of the cooling load given to the box cooler of 110 °C, 125 °C, 140 °C, and 155 °C. Then the temperature and pressure data is processed to get the COP value every time from all variations of the cooling load. The results showed that the increaseing in the cooling load, the smaller the COP value of the cooling machine. In its effect on the length of time the COP value of each variation of the cooling load increases.

Soil nutrients availability is one of the most important factors that determine the production of elephant food yam plants. However, there is no single nutrient source, either from inorganic fertilizers or organic fertilizers or biological fertilizers, which is able to meet all the nutrient needs of the plants grown. Therefore, integrated nutrient management (INM) of elephant food yam plants seems to be a way out to maintain sustainable production and increase profitability. This paper reviews the results of research on various issues of INM-based production management for elephant food yam plants and analyzes the extent of research on the use of INM both in Indonesia and abroad. The benefits of integrated nutrient management are well documented for vegetable crops. However, it is still very little available for elephant food yam plants, especially in Indonesia. Integrated nutrient management (INM) is a very important technological innovation to be applied to elephant food yam cultivation. Elephant food yam is a high nutrient consumeplant, so a wise and precise combination of inorganic and organic fertilizers as well as bio-fertilizer will result in sustainable and sinergistic use of soil nutrients of elephant foot yams. Therefore, recommendations for research need for INM of elephant food yam should be carried out in order to increase the production of it in a sustainable manner.","PeriodicalId":276781,"journal":{"name":"Jurnal Agrotek UMMat","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128716086","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}

The purpose of this research is to analyze tobacco farming income and to analyze farmers' perceptions regarding the policy of increasing excise tariffs on processed tobacco/cigarette taxes. The research method used is qualitative analysis with a descriptive analysis approach. The research was conducted in Suralaga District, East Lombok Regency. Suralaga sub-district was chosen because it is a sub-district that mostly cultivates tobacco commodities. Respondents used in this study were 30 respondent farmers. 15 farmers live in Bagik Payung Village, some 15 farmers live in Waringin Village. Both villages are tobacco farmers and are located in Suralaga District, East Lombok Regency. The results showed that tobacco farming in East Lombok Regency was declared feasible because based on the analysis, the farming experienced an income (profit) of Rp. 8,045,942/hectare/planting season with a farming feasibility level of 1.70> 1 (feasible category). Most farmers have the perception that the policy of increasing tobacco excise/cigarette tax aims to help the national economy through increasing state revenues, not to control the level of cigarette consumption. The local/central government has never socialized the increase in tobacco/cigarette excise. In addition, farmers also assume that the government has never provided assistance or compensation to farmers after the policy of increasing tobacco/cigarette excise. The increase in cigarette excise does not have a direct impact on the decline in the economic condition of farmers. The factors that have the most direct influence on farmers' income are uncertain weather conditions (climate change) and the determination of the selling price grade of tobacco harvests which is less transparent.","PeriodicalId":276781,"journal":{"name":"Jurnal Agrotek UMMat","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128465973","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}
