Abstract

Introduction: Tegal Panggung is a high population density sub-district of 26,326 inhabitants/km2. Most residents utilize wells to meet their water demands, but fecal coliform bacteria were found in several wells at Tegal Panggung. This type of contamination source is typically from on-site wastewater treatments. However, wastewater from Tegal Panggung is treated at a centralized wastewater treatment plant. This study is aimed at identifying the factors leading to the presence of fecal coliform bacteria in Tegal Panggung. Methods: Factors reviewed in this study were the amount of waste, drainage, cattle pens, toilets, types of wells, and building density. Statistical methods and GIS were applied to determine the influence of the factors on the presence of fecal coliform and to map its distribution along with potential sources of pollution. The number of wells tested was 32, with a research period from September to October 2021. The statistical methods used are the Kolmogorov-Smirnov Normality Test, the Spearman Correlation Test, and the spatial analysis method, which was carried out using QGIS. The statistical tests were conducted to determine the correlation value between fecal coliform and pollutant. Results and Discussion: The study showed that only 40.62% met the standard requirements when there should be no fecal coliform contents in well water. Conclusion: Based on the Spearman Correlation Test, it can be deduced that the factors affecting the presence of fecal coliform within 10 meters radius are garbage and of 30 meters radius are toilets and building density.

Abstract

Clean water is vital as it directly impacts health and influences various aspects of life, including social, economic, and cultural activities. To address the clean water supply requirements in the area, PERUMDA PDAM Sleman, Yogyakarta, is currently planning for a transmission network linking the Kregan WTP to the Watu Gadjah Tank. The pipeline planning is carried out to ensure efficient and optimal network performance. The pipeline planning use both primary and secondary data. The primary data was obtained from surveys, while the secondary data was obtained though previous research and planning, regulation, and from the other sources. The pipeline network analysis carried out using EPANET 2.2. software. EPTANET was selected because of its cost-effectiveness and robust capabilities in modeling drinking water networks, with the advantage of being re-programmable. The results of the analysis are then adjusted to the planning standards that applicable in Indonesia. Risk analysis was carried out based on experience and expert opinion. The results of the planning showed that the maximum pressure on the transmission network was 84.21m on Pendowo Road. The velocity between 1.03 m/s and 1.63 m/ss with the highest headloss was 10.33 m/km. Based on the results of the planning, the entire parameter meets the standard of the applicable planning criteria. The results of the analysis indicate that the technical specifications of the pipe used must be able to withstand a pressure of 92,63m. There was a potential risk that network performance may be disrupted both in terms of network performance, implementation of development, and operational stages. The re-examination and the development of operational standard procedures is needed to ensure that planning has been in line with the expectations, can be implemented, and can be operated efficiently.

Abstract

Desa Wisata Jetis terletak di Kelurahan Jatinom yang memiliki upacara adat bernama Yaa Qowiyyu dan diselenggarakan setiap bulan Sapar. Taman Goa Jetis berada di Kawasan Makam Ki Ageng Gribig yang menjadi tempat berkembangnya Islam di Tanah Jawa. Goa yang terletak diantara dua taman tersebut saat ini dibuka untuk umum dan digunakan sebagai tempat berziarah. Dengan dibangunnya tempat wisata ini, dibutuhkan adanya sarana pendukung salah satunya tempat ibadah. Tujuan PKM ini yaitu pembangunan Mushola sebagai sarana pendukung dari Taman Goa Jetis ini. Pembangunan Mushola ini dilakukan dengan empat tahap, yaitu melakukan analisis masalah dengan mengobservasi lokasi pembangunan Mushola, melakukan perencanaan desain berdasarkan data observasi yang didapatkan, melakukan pendataan material dari desain yang dibuat, dan melaksanakan pembangunan. Pembangunan Mushola ini dilaksanakan oleh keterlibatan masyarakat setempat dan tim PKM. Kendala yang dihadapi selama pembangunan Mushola antara lain mobilisasi material, faktor alam, pengerjaan secara manual, dan keterbatasan alat.
