Abstract

Occupational Safety and Health is a crucial aspect in operational activities in the industrial sector, including the livestock industry such as PT. Q. In large-scale livestock activities, potential hazards to workers, livestock, and the surrounding environment can arise from various routine activities, such as waste processing and maintenance of existing facilities. Therefore, the implementation of an OHS system is needed to minimize work risks and ensure the continuity of safe and efficient operations. This study aims to determine the risk of work accidents, classify potential hazards, and evaluate and provide additional risk controls in the sandtrap and heifer areas of PT. Q. The FMEA method has the advantage of being able to explain various risks in detail and comprehensively, helping to improve future work, and is able to identify accident risks based not only on one criterion, but also on three criteria: severity, frequency of occurrence, and detectability. The data collection used was obtained from interviews with 7 respondents, observations, and documentation. The data collection techniques used were interviews and direct practice. Therefore, some suggestions that can be given are using remote operator tools in the machine operator section, adding protection to the screen section and moving roller separator machines, carrying out routine maintenance on the roads used, installing K3 signs in every road traffic, providing first aid kits in every department, and providing K3 socialization to all company staff involved.

Abstract

Introduction: The presence of microplastics in the environment increases the diversity of types of pollutants in waters, including clean water sources on the surface and underground. Karst areas have unique hydrological characteristics, with cracks and fissures between the rocks that can be potential routes for the transport and accumulation of microplastics in underground river flows. In this study, we want to know the distribution and abundance of microplastics in underground rivers in the karst area of South Malang, Indonesia. Methods: Samples were collected purposively from underground river of Lowo, Banyu and Sengik. Microplastics were prepared using a diluted solvent of 30% H2SO4 and 30% H2O2. The sediment sample was dried and then filtered twice using 300-mesh size nylon filters until microplastic particles accumulated. Results and Discussion: Microplastics were detected in all water samples, with an average abundance ranging from 1.8 to 2.3 particles per liter. Fibers were the dominant microplastic type, followed by fragments and films, while the color distribution includes blue, white, red, yellow, black, green, pink, and brown. Conclusion: Microplastic contamination has been found in underground river flows in the karst area of South Malang, Indonesia. Karst soil, traditionally viewed as a natural filter, is not impervious to plastic pollution. This suggests significantly higher surface contamination than previously assumed. Therefore, reducing surface pollution is essential to safeguard the precious quality of underground aquifers and protect public health above.

Abstract

An increase in the population growth rate leads to a rise in the need for housing. Housing development can reduce water catchment areas, potentially leading to increased flooding. This drainage system planning aims to determine the flood discharge and channel capacity. The hydrological analysis employs the Gumbel distribution method to determine rainfall with return periods of 5 and 2 years. Rainfall for the 2- and 5-year return periods is equal to 109.5 mm/hr and 136.8 mm/hr. Furthermore, the hydraulic analysis for channel drainage capacity uses the continuity equation and SWMM 5.2 modeling. The results of the hydraulic analysis showed that the channel capacity can accommodate the flood discharge. This is reinforced by the modeling results, which state that the whole conduit and junction can accommodate the flood discharge. This is based on the simulation results of channel conduits that are not red. The channel conduit is marked with green, blue, and yellow markings. This indicates that the planned channel has complied with planning rules. Based on the results of research and planning of the residential drainage system in X Sidoarjo Regency, it can be concluded that the drainage channel plan’s capacity is sufficient to accommodate flood discharge. This is based on mathematical calculation results and modeling simulation results from the SWMM (Storm Water Management Model).

Abstract

Penelitian ini bertujuan untuk menganalisis kualitas air tanah terkait penecemaran bakteri Escherichia coli di Desa Prasung, Kecamatan Buduran, Kabupaten Sidoarjo berdasarkan pada pengaruh penataan jarak sumur gali terhadap tangki septik. Penelitian ini dilatarbelakangi oleh tingginya angka kejadian diare di wilayah tersebut, yang diduga disebabkan oleh pencemaran air tanah Penelitian dilakukan dengan metode survei deskriptif, menggunakan sebanyak tujuh sumur gali dengan perwakilan tiap RW yang ditentukan dengan cluster sampling sehingga didapatkan tujuh titik sampling. Data yang dikumpulkan meliputi tinggi bibir sumur, elevasi, kedalaman MAT (Muka Air Tanah), jarak antara sumur gali dan tangki septik serta pengurasan rutin dan bidang resapan pada tangki septik. Metode yang digunakan untuk pemetaan pola aliran air tanah di Desa Prasung adalah metode Inverse Distance Weighting (IDW) dengan perangkat lunak ArcGIS 10.8. Penataan jarak sumur gali dengan tangki septik yang kurang dari 10 meter ditemukan berkontribusi terhadap tingginya tingkat pencemaran Escherichia coli pada beberapa titik. Selain itu, pengurasan tidak rutin pada tangki septik, tidak adanya bidang resapan pada tangki septik, dan faktor lingkungan dapat menjadi pencemaran E. coli pada sumur gali. Pola aliran air tanah di desa ini mengalir dari barat ke tenggara, sehingga penataan tangki septik terhadap sumur gali tidak ada yang searah dan tidak menjadi faktor adanya E. coli pada sumur gali.

Abstract

PT "X" is the largest steel pipe manufacturing company in Indonesia. The process that starts from the entry of semi-finished materials to the form of pipes that have been packaged certainly has a risk of danger. Thus, an organization must obtain procedures regarding hazard identification, risk assessment, and determining control commonly known as HIRADC. This study aims to analyze occupational safety and health risks using qualitative descriptive methods through a worker safety risk analysis approach. The object of the research is focused on the activities of the stainless steel pipe production process at PT "X" which includes three stages, namely the pipe formation process, the buffing process, and the packaging process. Based on the results of the analysis carried out, there are potential hazard risk sources in the Tolerable (TL) and Moderate (MD) categories. The observed activities can be identified as having 46 K3 risks. From the results of the risk assessment, 39 K3 risks with a percentage of 85% are at the Tolerable risk level (TL). A total of 7 K3 risks with a percentage of 15% are at the Moderate risk (MD) level. PT "X" control efforts include engineering 13%, administration 42%, and PPE 45%. Control recommendations are given at a moderate level and some at a tolerable level, including through painting the boundary line of workers' roads, replacing remote control cranes, conducting safety briefings, adding safety signs, providing guardrails, and replacing pipe cutting tools.

Abstract

Livestock waste is a type of waste produced from livestock activities. Problems caused by livestock waste include unpleasant odors that can interfere with breathing. This problem is caused by ammonia (NH3) and hydrogen sulfide (H2S) gas. This study aims to analyze the results of processing cow manure using MOL to be used as fertilizer in accordance with the Decree of the Minister of Agriculture of the Republic of Indonesia concerning Minimum Technical Requirements for Organic Fertilizers, Biofertilizers, and Soil Improvers in 2019. Cow manure has the potential to be used as compost. The content of nutrients such as Nitrogen (N), Fosfor (F), and Potassium (K) can increase soil fertility. The composting process can be carried out by adding materials containing microorganisms that decompose MOL. The fermentation process is carried out for 4 weeks. Changes that occur during the fermentation process include an increase in temperature and a dark brown color. Based on the test results, there was a decrease in the content of solid fertilizer. This is due to the fermentation time factor. The longer the fermentation time, the more nutrients are used for microorganism activity. This causes the availability of nutrients to decrease and be depleted. Experiments with better results can be carried out by reducing the length of the fermentation time. Further experiments can be carried out using solid manure waste as an additional nutrient in organic fertilizer made from vegetable juice.
