Abstract

Baglog waste produced by farmers can pollute the air and soil around the disposal site. Its main composition is sawdust which still stores energy so that it can be used as a raw material for briquettes. Briquettes require adhesives to glue the charcoal particles so that they do not break easily. Banana peels have fairly high pectin content so that they are suitable for use as briquette adhesives. The purpose of this study was to analyze the effect of using variations in the composition of oyster mushroom baglog waste (Pleurotus ostreatus) and kepok banana peel adhesive (Musa paradisiaca L.) on the quality of briquettes. This study was a type of experimental research with quantitative descriptive analysis. Formulation of variations in the comparison of baglog waste and banana peel sample 1 (60%:40%); sample 2 (50%:50%); sample 3 (40%:60%). The results of the study show that the best variation was in sample 3, namely water content, ash content, volatile matter content, bound carbon content and the best calorific value, respectively, including 5.63%, 38.10%, 50.86%, 11.04% and 3546 cal/gr. The use of variations in the composition of baglog waste and banana peels in this study did not have a significant effect on the quality of the briquettes produced. Therefore, the use of mushroom baglog waste and banana peels as raw materials for briquettes is not optimal because it does not meet SNI.

Abstract

The management of medical liquid waste is an important aspect in efforts to maintain environmental quality and public health. This study aims to analyze the effectiveness of medical liquid waste management at the Sakra Barat Health Center, East Lombok Regency, based on quality standards set forth in the Ministry of Environment Regulation No. 68 of 2016. The research method used is a quantitative approach with testing of waste samples before and after treatment in the Wastewater Treatment Installation (IPAL). The results show that before treatment, several waste parameters such as BOD (139 mg/l), COD (825 mg/l), and TSS (282 mg/l) exceeded the established quality standards. However, after treatment, these values significantly decreased and met the quality standards, with TSS values of 2.50 mg/l at an effectiveness percentage of 99.11%, BOD of 1.53 mg/l at an effectiveness percentage of 98.90%, COD of 38.0 mg/l at an effectiveness percentage of 95.39%, and a pH value of 7.26. This indicates that the IPAL at the Sakra Barat Health Center is effective in processing medical liquid waste, ensuring that the discharged waste is safe and does not pollute the environment.

Abstract

The process of re-filtering or filtration of sample water in the IPA IKK Pandan Duri reservoir tank is due to the parameter levels that sometimes do not meet the quality standards according to PERMENKES No. 2 of 2023 concerning the Standards for Water Needs for Hygiene and Sanitation. Several factors causing the high levels of parameters in the water that has been filtered by the PDAM unit branch include, among others, the insufficient amount of filtration media used, corrosion in the filtration equipment (WTP), and/or the reservoir not being cleaned regularly. This leads to the filtered clean water becoming re-contaminated, so sometimes the clean water ready to be supplied to the communities in Desa Keruak and Jerowaru gets contaminated again. This research uses experimental research methods and descriptive analysis. Results obtained: pH levels experienced a concentration decrease of 0.22 mg/l with an effectiveness of 50.76%; NTU with a decrease of 12.44 mg/l with an effectiveness of 97%; TDS levels decreased by 315 mg/l with an effectiveness of 83.72%; Fe reduction was 0.963 mg/l with an effectiveness of 98%; lastly, the NO3 parameter with a decrease of 21.98 mg/l and the highest effectiveness reaching 99%.

Abstract

Plastic waste has polluted the marine and coastal environment of Labuhan Haji Beach, East Lombok Regency. Plastic waste can decompose in the environment into smaller particles, measuring less than 5 mm, called microplastics. The very slow plastic degradation process causes microplastics to continue to exist in the environment for a long time. Microplastics continue to accumulate in the environment and enter the food chain, threatening the sustainability of the ecosystem. This study aims to determine the presence of microplastics and to identify the types, colors, quantities, and abundance of microplastics in sediments on the Labuhan Haji Coast. Sampling was carried out at 5 station points determined by the purposive sampling method. The identification results found microplastics in sediment samples taken from the Labuhan Haji Coast. Identification of the types of microplastics in the samples found foam (78%), Fragments (13%), Film (7%) and Fiber (2%). The results of the color identification obtained 8 microplastic colors, namely black (65%), white (17%), green (7%), blue, transparent (3%), yellow (2%), red (1%), and orange (0.003%). The total number of microplastics found was 634 microplastic particles. The highest abundance of microplastics was 4190 particles/kg and the lowest abundance was 320 particles/kg.

Abstract

Livestock is an agricultural sub-sector that plays a very important role in providing food needs, especially animal protein. The more chickens there are, the more manure will be produced so that the Ammonia Gas (NH3) will be higher. The research method used is the observational research method, which is descriptive analytical with a cross-sectional approach. Based on the results of observations made on broiler chicken cage workers, most respondents agreed that the smell of ammonia (NH3) in broiler chicken cages disturbed their sense of smell. Most respondents had the answer. For measurements at points 2 and 3, there was a lower average NH3 concentration., this is because there is not too much broiler chicken waste and there is not too much activity in the cage at points 2 and 3 so the NH3 concentration is low. Most of them had answers agree with values ​​38, 38, 38, 38, 39, 43, 45, 48, and some had answers quite agree with values ​​30 and 33. It can be concluded that exposure to ammonia gas (NH3) is high in the environment. Broiler chicken cages have a negative impact on workers' sense of smell, and can increase the risk of partial anosmia (partial loss of the ability to smell) in broiler chicken cage workers. As many as 80% of respondents agreed that impaired sense of smell was caused by the smell of ammonia. These disorders not only reduce workers' quality of life, but also have the potential to affect their performance in carrying out daily tasks.

Abstract

The limited availability of clean water, unable to meet the ever-increasing demand, raises concerns for the community. Therefore, an analysis of the clean water balance is necessary to ensure an adequate water supply. This study aims to calculate the availability of clean water, assess water needs, and analyze the clean water balance in Joben Hamlet, Pesanggrahan Village, Montong Gading Subdistrict, East Lombok Regency, in 2024. The research method used was a descriptive quantitative approach, with data comprising primary and secondary sources. Data collection techniques include observation, direct field measurements, interviews with local residents, and documentation related to water resources in the area. Data analysis techniques involve calculating water availability, water needs, and the status of the water balance in the hamlet. The study results show that the primary water sources in Joben Hamlet come from springs, rivers, water reservoirs, and groundwater. These sources were sufficient to meet domestic and non-domestic water needs. The water requirement per household is calculated to be 165 liters/day, assuming an average household size of five people, each needing 33 liters per day. The total domestic need for 226 households amounts to 37,290 liters per day. The total water availability recorded over one day is 3,457,368.248 liters, while the water requirement is only 1,767.227 liters. Thus, there is a surplus of 3,455,601.02 liters per day. This balance indicates that the area still has abundant water resources, capable of meeting future community needs and supporting other economic sectors.

Abstract

The development of neighborhood-scale parks plays an important role in providing community-based public facilities tailored to local environmental and social needs. In Alalak Selatan Subdistrict, Banjarmasin, the presence of wetland terrain and tidal conditions requires a site-specific approach in project planning and execution. This study analyzes the application of project management principles in the design and conceptualization of a community park in such challenging conditions. A qualitative case study method was used, utilizing Google Earth imagery for site analysis, AutoCAD for technical design, and SketchUp for 3D visualization. Project components such as the Work Breakdown Structure (WBS), estimated Budget Plan (RAB), scheduling, and quality control aspects were reviewed in line with standard project management practices. The results show that adaptive planning, cost estimation based on local material prices, and risk identification strategies contribute significantly to ensuring feasibility and functionality. This approach offers a practical reference for small-scale public facility projects in similar environmental contexts.
