Inggili is a type of mangrove plant that has been traditionally used by the community for medicine. It contains many active compounds that function as antibacterials. Based on empirical data, inggili fruit is used to remove acne on the skin and diarrheal diseases. This study aims to determine the antibacterial activity of methanol extract of inggili pulp in inhibiting Propionibacterium acnes and Escherichia coli bacteria using the sumuran diffusion method. The research conducted is experimental. The object under study was the antibacterial activity of inggili fruit extract against Propionibacterium acnes and Escherichia coli bacteria. Antibacterial activity was tested using the sumuran diffusion method with extract concentrations of 10%, 15%, and 20%. The negative control used was 1% DMSO and the positive control used was 0.1% chloramphenicol

The overuse of chemical fertilizers can have detrimental effects on soil quality. It is important for farmers to find sustainable alternatives. One possible solution being explored is the use of liquid maggot derived from organic sources. This study aimed to determine the most suitable composition that fulfills plant needs and follows established guidelines. The research approach employed a qualitative descriptive method to assess the impacts of three treatments using different types of organic matter: fruit waste, restaurant waste, and palm oil cake. Phosphorus and potassium concentrations were determined through MP-AES analysis while nitrogen content was measured using the Kjeldahl method. The findings revealed that only the treatments involving fruit waste and restaurant waste met the recommended potassium levels. However, these treatments fell short of meeting requirements for other essential nutrients. As a result, additional research is needed to assess nutrient concentrations in different organic substances.

The use of information technology in the field of education aims to make educational organizations or institutions more efficient. One example of information technology in the world of education is building a school information system, one of which is the academic information system for Madrasah Aliyah Raudatul Yatama. Based on the evaluation results of improving the quality of the Raudatul Yatama Madrasah Aliyah information system, the suggestions for improvement that are the focus are the measurement aspects that direct the user interface to a simpler level but have high usability. Because more than half of the respondents stated that the user interface still needs development both in terms of appearance and usability, Therefore, the developer of the Madrasah Aliyah Raudatul Yatama information system can focus more on the aspects included in these criteria for better system quality.

Abstract Embelia borneensis known sekilang used by the Dayak Kenyah tribe of Long Temuyat Village, Malinau, North Kalimantan as a fish poison and leech repellent. Sekilang bark extract contains alkaloids, tannins, saponins and flavonoids compounds. The purpose of this study was to determine the type and content of saponins in the methanol extract based on different maceration, reflux, and Soxhlet extraction methods. Saponin content was determined by the gravimetric method. The results showed that the type of saponin contained in sekilang bark extract was triterpenoid saponin. The average saponin content with maceration method was 24.87%, reflux method was 28.97 and soxhlation method was 29.99%. The results of data analysis with one-way anova statistical test showed that there was a significant difference between extraction methods on saponin content of sekilang stem bark with sig value of 0.009 with a significant level of 0.05 (5%).

A reduction in rice quality may result from pest infestations in storage facilities. In addition to being a major pest of rice, the rice weevil (Sitophilus oryzae L.) is a problem in warehouses. Attacks by rice weevils may result in lower-quality rice. Using white pepper powder as a pesticide is one way to solve this issue. The purpose of this study is to ascertain how white pepper powder, a botanical pesticide, affects rice weevil pest mortality, as well as the optimal dosage and mode of administration. In this study, there were six treatments and four replications in a single factor totally randomized design. The rate at which rice weevil bugs died and the percentage of rice weight loss were the study's parameters. The results showed that the death of rice weevil pests was influenced using white pepper powder. The highest mortality rate was L5 at 52.5%, which is the best dose.

The purpose of this review article is to provide information about edible film, materials used, manufacturing methods, application for food packaging, and opportunities for future benefits of edible film. The method used by the author in reviewing this article, is by reading various journals from other authors and write the conclude using author own language. The conclusion is, edible film has potential to replace plastics (synthetic polymers) as food packaging. The ingredients used for edible film production are hydrocolloid (protein, polysaccharides, and alginates), lipid (polysaccharides, and alginates) and composite (mix of hydrocolloid and lipid). The methods for edible film production are wet process and dry process. Edible film can be used as food packaging, including cheese, meat, fish, vegetables, and fruit. Prospect of edible film has the potential to increase in the future because people are realizing the importance of reducing food waste with ecofriendly material as food packaging.

PT Goodyear Indonesia Tbk is a tire manufacturing industry whose main need is the provision of water for steam boiler decoys. This water is obtained from groundwater and surface water such as river water which is then treated in a reactivator using one of the coagulants, namely PAC, so that impurities from river water can be removed, so the water is cleaner and can be used for steam boilers and does not interfere with a further decoy water treatment. This study aims to determine the effectiveness of water treatment in reactivators to be a reference for further treatment considerations at PT Goodyear Indonesia Tbk. The test result data showed the efficiency value between the inlet and outlet and compared it with the control limit set by the company. The efficiency test parameters consist of pH, conductivity, clarity measurement, and color measurement. Based on the results of efficiency calculations, several test parameters show that water treatment in reactivators at PT Goodyear Indonesia Tbk is still good and has a high-efficiency value.

Primary data is the main source of data for the investigation of the subsurface with the Vertical Electric Sounding (VES) method. The purpose of the study is to determine the resistivity of subsurface geological conditions to detect aquifer and reservoir lithology types designed as planned wells. The data of geoelectric investigation point was carried out on as many as 10 (ten) points and produced in the form of (1) Claystone: resistivity of 1.4-6.4 Wm and thickness of 4-4.6 meters, (2) Sandstone: resistivity of 7.5-40 Wm and thickness of 0.2-55 meters, (3) Breccia: resistivity of 45-1088 Wm and thickness of 0.5-33.2 meters.
