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

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.

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.
