Abstract

Compost is one of the products resulting from the Industrial Waste Processing practicum in the form of solid waste. This compost goes through a composting process and becomes one of the organic fertilizers containing macro and micronutrients. Compost is produced through the biological decomposition process of organic material, which is controlled and results in humus. Moisture content is one of the key factors in the composting process, and it is essential for determining the maturity and quality of compost. Moisture content refers to the amount of water in a material or object, such as soil (also known as soil moisture), agricultural materials and products, rocks, etc. Additionally, compost fertilizer contains nutrients such as nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and other elements. Based on testing, the sample rice husk: TSP 3:2:2 moisture content was 40.74%, and for another rice hull: TSP 3:2:2 sample, it was 43.14%. rice hull: TSP 3:2:2 had 0.74% for nitrogen content testing, and the second sample had 0.76%. Phosphorus content testing for rice husk: TSP 3:2:2 was 0.28%, while the second sample had 0.18%. rice husk: TSP 3:2:2 had 0.53% for potassium content testing, and the second sample had 0.509%. From these test results, it can be concluded that both samples meet the standards of SNI 19-7030-2004 for compost specifications from domestic organic waste. This research is expected to provide information on the quality of the bokashi fertilizer and be a reference in developing more optimal waste processing methods.

Abstract

A driving License (SIM) is a card that a motorized vehicle driver must own to prove the eligibility to drive a motorized vehicle. There are still many drivers who do not have a SIM. One of the reasons drivers don't apply for a driving license is because they object to follow every procedure in making a driver's license, which takes a long time and causes long queues every day. The application for a driver's license in a city or district is only in one place, namely at the City Police. As a result, many applicants apply for a driver's license in the queue system. This problem also occurs in the SIM-making service system at the Sumbawa Police Station. Therefore, this study aims to evaluate the queuing system for SIM-making services at the Sumbawa Besar Resort Police using the queuing theory method. There are two types of submissions in applying for a SIM, namely a new application and an application for an extension of a SIM, and the queuing system model used is Single Channel-Multi Phase. There are three phases in applying for a new SIM: the registration phase, photo phase, and test phase. Meanwhile, the application for a SIM extension has two steps: registration and photos. Based on the results of the analysis, the use of one service in each phase has not been optimal in overcoming the number of queues in the new SIM application process because there is still a steady-state (ρ) greater than one and the number of applicants is still queuing in the system, namely on Monday (phase test), Wednesday (test phase) and Friday (photo phase and test phase). Therefore, it is proposed to add one more service on that day and phase so that the stadium condition (ρ) is less than one and there is only one applicant in the queue (Lq).

Abstract

Sumbawa is an area that has minimal waste processing, especially plastic. Processing plastic waste needs to be done to prevent freezing, especially on beaches. This is because plastic waste is waste that is difficult to decompose. One of the areas that produces a lot of plastic waste in Sumbawa is Labuhan Village. Therefore, efforts need to be made to minimize the amount of waste in Labuhan Village by processing it into paving blocks. The aim of this service activity is to provide outreach and training on making paving blocks from plastic waste. This is done to improve the human resources of the Village Community in minimizing existing Plastic Waste. The method used is through socialization, delivery of material and direct question and answer discussions to the community and direct training related to making plastic paving blocks. Before carrying out the training, the community was given pretest questions and ended with post-test questions. The results obtained from this activity are an increase in the ability of village residents to process plastic waste into paving block products. This can be seen from the increase in public understanding by 68% as seen from the comparison of the pretest and post-test results. Apart from that, the community is also able to directly instill the process of making paving blocks from plastic waste, so that the community can utilize this understanding by making it independently and making it a side business in minimizing the accumulation of plastic waste. This community service activity is able to provide understanding and abilities to village residents in processing plastic waste into paving blocks.

Abstract

XYZ is a State-Owned Enterprise (BUMN) engaged in the construction sector. One of the infrastructures currently being built by PT. XYZ is the Construction of the Lombok Peaker PLTMGU Jetty in Mataram. Based on the results of observations, it was found that there was a risk of danger to welding workers that could cause work-related illnesses in spun pile welding workers or piles, so further analysis is needed. This study aims to analyze work postures and complaints and provide suggestions for welding work at PT. XYZ on the Lombok Peaker PLTMGU jetty construction project. The methods used are the Rapid Entire Body Assessment (REBA), Nordic Body Map (NBM) and tree diagram methods. The results of the study obtained REBA on the first, second and fourth welders were at a high risk level. The results of the Nordic body map score for welder 1 are in the moderate category, meaning that corrective action may be needed. Several workers filled out complaints of pain in several parts of the body. The proposed improvements are adequate rest, adjusting the height of the pile to be welded to the height of the welder, the welder welding with a more upright body, and providing a chair for the welder. It is expected that this research can minimize the risk of work-related illness in welding work at PT. XYZ on the Lombok Peaker PLTMGU jetty construction project.
