Abstract

Bio briquette is a briquette based on agricultural waste because it is deliberately made from biomass charcoal. The utilization of agricultural waste such as mushroom planting media to be processed as bio briquette requires a very cheap cost. Bio briquettes that are processed properly and correctly, will produce high-quality briquettes. The purpose of this study was to produce a biobriquette from baglog mushroom waste and to determine the characteristics of the biobriquette. The research material used consisted of 400 grams of mushroom baglog waste and 40 grams of starch as adhesive. The briquette dough is then printed cylindrical. The printed briquettes are then heated at 80°C for 5 hours to reduce the moisture content. The result of smoke test is the smoke will stop in 17 seconds with the color of the smoke is white. The Combustion of speed test, the results obtained are 0,0019 gram/second with an initial sample weight of 2, 4 grams and burning for 20 minutes 35 seconds with a final sample weight of 0,387 grams. The result of ash content is 0.16%. This result is in accordance with the SNI issued by our government. SNI of ash content is max 8 %.

Abstract

Plastic food packaging has become a part of human daily life. The management of plastic waste is a matter of concern due to its potential which is difficult to decompose. This condition causes all producers to have a responsibility not only during the manufacturing process but until the end of the life of their products. This expanded responsibility is called EPR (Extended Producer Responsibility). Therefore the resulting packaging design becomes a breakthrough in this matter. This research attempts to apply the Kansei Engineering method to capture customers' emotional needs from consumers in compiling plastic packaging design parameters. The research method in this paper uses the Kansei Engineering method, namely by collecting Kansei words from respondents at random, then the Kansei words are reduced. The reduced Kansei word will be synthesized to produce quality attributes that are able to meet the customer's emotional needs. The Kansei words obtained from the survey results are 55 words. Packaging quality attributes that have met the customer's emotional needs include protection, refillable, recyclable, biodegradable, food safety, additional function, attractiveness, conformity, ergonomic, user friendly, and content declaration (on the packaging label).

Abstract

The commitment to provide clean water and proper sanitation is one of the goals of the Sustainable Development Programs (SDGs). The government of each region needs to strive for clean water for the community. Efforts to provide clean water can be realized with the Water Supply System. Water Supply System sustainability indicators need to fulfill three aspects of quality, quantity, and continuity. The aim of this research was to assess the sustainability of the ‘Sugio’ Water Supply System in Lamongan Regency, which served three villages, namely Sugio, Lebakadi, and Sekarbagus. The aspect of water quality, seen from the results of the analysis of the quality of production water, met the quality standards for drinking water. The aspect of water quantity was calculated to meet water needs for the next 20 years. The calculation showed that the daily average debit requirement was 17 L/s and the daily maximum debit was 19 L/s, while the existing debit was 15 L/s. The aspect of water continuity was calculated by the ability to distribute water during an emergency. The calculation showed that the distribution of clean water when there was no source of electrical energy could only be carried out in a maximum of 1 hour, 13 minutes, and 48 seconds. The conclusion obtained was that the sustainability of the ‘Sugio’ Water Supply System from the perspective of water quantity and continuity needed to be improved.

Abstract

Neutralized Crude Gypsum (NCG) is produced as by-product from phosphoric acid plant at Plant IIIA PT. Petrokimia Gresik. The aims of this study are finding main cause and solution from Neutralized Crude Gypsum (NCG) quality reduction at PT. Petrokimia Gresik Plant IIIA. This research is done by qualitative analysis in order to collect the data of gypsum quality every month. Gypsum characteristics is observed by some instrument analysis such as spectrophotometry UV-Vis, atomic absorption spectrometry (AAS), and gravimetry technique. NCG was taken at different point on gypsum disposal land and different times to analyze its quality change. NCG sample shows decreased quality having higher moisture content at September that does not comply the SNI 715:2016 about gypsum minimum quality. Flash dryer is designed in this study to reduce the water concentration inside the surface of gypsum particle. Flash dryer design can lower the H2O content based on material balance analysis at finishing sector Plant IIIA unit.

Abstract

Biogas is a gas generated through anaerobic processes that involve the decomposition of organic materials. Various sources of methane can be utilized to produce biogas, including household waste, biodegradable waste, animal waste, or organic materials that can break down under anaerobic conditions. The objective of this study is to investigate how different conditions, such as time, pH levels, stirring duration, and the type and concentration of inoculum, influence biogas production, with the aim of identifying the optimal conditions for the biogas production process. This research focused on examining the factors that impact the biogas production process, which includes several stages like hydrolysis, acetogenesis, acidogenesis, and methanogenesis. The findings from prior experiments showed that the optimal biogas production was achieved using tofu liquid waste, resulting in a volume of 26,700 ml over a 36-day period. This was achieved by maintaining an operating temperature between 35-40°C and employing cow dung as the inoculum, along with a 36-liter digester.
