Air bersih merupakan kebutuhan pokok yang sangat penting bagi kehidupan manusia. Seiring dengan pertambahan dan perkembangan penduduk kebutuhan akan air bersih juga semakin meningkat, untuk itu perlu dilakukan analisis terhadap sistem jaringan perpipaan eksisting. Penelitian ini dilakukan dengan bantuan Pamsimas Sendang Lumintu Desa Sendangkulon Kecamatan Kangkung yang bertujuan untuk mengetahui kondisi eksisting sistem jaringan perpipaan Pamsimas Sendang Lumintu untuk tahun 2024 , mengetahui berapa besar kebutuhan air yang dibutuhkan untuk memenuhi pertumbuhan penduduk sampai dengan tahun 2039,  dan menganilisi kondisi eksisting sistem jaringan perpipaan Pamsimas Sendang Lumintu untuk tahun 2039. Metode yang digunakan dalam penelitian ini adalah dengan mengumpulkan data sekunder lalu menganalisis data tersebut dengan program EPANET 2.0 sehingga didapatkan hasil simulasi. Hasil simulasi menunjukan bahwa pada tahun 2024 besar debit kebutuhan rata-rata yaitu sebesar 16,27 liter/detik, kebutuhan harian maksimum 17,90 liter/detik dan kebutuhan jam puncak 24,40 liter/detik. Sedangkan untuk tahun 2039 besar debit kebutuhan rata-rata yaitu sebesar 20,92 liter/detik, kebutuhan harian maksimum 23,01 liter/detik dan kebutuhan jam puncak 31,38 liter/detik. Kondisi hidrolis eksisting sistem jaringan Pamsimas Sendang Lumintu Kecamatan Sendangkulon masih ada yang tidak sesuai kriteria. Kriteria yang dianalisa adalah sisa tekan dan kecepatan air. Pada jam puncak terdapat beberapa titik yang menghasilkan sisa tekan kurang dan kecepatan dibawah kriteria

Clean water distribution in the Community-Based Drinking Water Supply and Sanitation Program (PAMSIMAS) in Kuwasen Lama Village, Gunungpati District, Semarang City, faces the challenge of unequal supply between highland and lowland areas. The main factors that affect these conditions include differences in topography, suboptimal piping network design, and unbalanced water pressure, especially during peak hours. This research proposes a solution based on Internet of Things (IoT) technology using the ESP32 module as a control center, which is integrated with the Blynk application for real-time monitoring and control of the system. The system is equipped with a water flow sensor, water level sensor, motorized valve, and booster pump to increase water pressure in high elevation areas. Two design schemes were tested, namely flow regulation using a motorized valve, and a combination of a motorized valve with a booster pump. The results of the simulation and implementation showed an increase in water pressure stability, equitable distribution, and a decrease in the frequency of supply disruptions. The system also allows for live monitoring of network conditions, facilitates technical decision-making, and improves operational efficiency. With an adaptive and community participation-based approach, this solution has the potential to become a model for PAMSIMAS clean water distribution management that is efficient, sustainable, and responsive to geographical challenges, while strengthening the resilience of clean water services in rural areas.

The Community-Based Sanitation Program (PAMSIMAS) is a government initiative aimed at improving community access to proper sanitation facilities, particularly in rural areas. This study aims to evaluate the effectiveness of the program in Tanjung Aman Village, Wampu District, Langkat Regency. A qualitative approach was used with a phenomenological method, focusing on the experiences and perceptions of local residents and village officials regarding program implementation. Data were collected through in-depth interviews, field observations, and documentation, involving 15 informants comprising residents, sanitation cadres, and village officials. The findings show that technically, the sanitation facilities function well; however, sustainability in usage faces challenges such as low community participation, weak maintenance systems, and the absence of binding local regulations. Community perception of the program is generally positive, particularly regarding improvements in environmental cleanliness and comfort in using the facilities, yet unequal access remains a significant issue. The study concludes that the success of PAMSIMAS largely depends on collaboration among the community, local cadres, and village policies. Strategic recommendations include the formulation of Village Regulations, regular training for cadres, and the establishment of a community-based sanitation management institution. With this approach, the program is expected to operate sustainably and provide long-term benefits to rural communities.

K- means termasuk kedalam algoritma partisi yang memiliki tujuan untuk membagi data kedalam jumlah  klaster yang ditentukan, hasil dari algoritma K means tergantung pada pemilihan pusat klater awal  namun permasalahan yang sering terjadi jika pada pemilihan centroid awal yang masih dilakukan secara acak jauh dari solusi maka kemungkinan hasil dari pengelompokan tersebut kurang tepat. Untuk mengatasi masalah tersebut akan menggunakan tahapan preprocessing berupa normalisasi minmax untuk mengatasi skala pengukuran berbeda pada dataset, setelah itu menggunakan algoritma PSO dalam pemilihan centroid awal untuk algoritma K- means, dalam penelitian ini juga dibandingkan pemilihan centroid dengan 3 cara yang pertama sesuai dengan acak, kedua sesuai standar pemerintah untuk nilai kualitas air minum yang tingi, menengah dan rendah kemudian yang ketiga dengan metode yang diusulkan algortima PSO dan kemudian akan diuji dengan Index Davies Bouldin. Hasil pengujian berupa tersebut metode K-means dengan pemilihan centroid awal acak dengan nilai 0,208856082, metode K-means dengan pemilihan centroid sesuai dengan standar pemerintah tentang kondisi SAM  sebesar 0,280077, dan terakhir metode pemilihan yang terbaik adalah dengan menggunakan normalisasi minmax K-means PSO dengan nilai 0,177796. Sehingga pengujian data PAMSIMAS menggunakan normalisasi minmax k-means PSO yang didapat bahwa metode tersebut lebih optimal

The Community-Based Drinking Water and Sanitation Provision Program (PAMSIMAS) aims to increase access to clean water and proper sanitation in rural areas. However, the implementation of this program in several villages, including in Lubuk Ulak Village, Muara Pinang District, Empat Lawang Regency, still faces various challenges. This research aims to evaluate the PAMSIMAS development policy in the village, focusing on the effectiveness of implementation, the challenges faced, and its impact on the local community. This study uses a descriptive qualitative approach with a case study design. The data collection techniques used were in-depth interviews, observations, and document studies related to the implementation of PAMSIMAS. The collected data was analyzed thematically to find patterns relevant to the research objectives. The results show that although PAMSIMAS has succeeded in providing clean water infrastructure, there are still problems in terms of water resource management, community participation, and facility sustainability. Lack of technical training for local managers and weak coordination between stakeholders led to the insustainability of programs at the village level. In conclusion, PAMSIMAS in Lubuk Ulak Village needs improvements in planning, community involvement, and institutional capacity strengthening. Further research is needed to explore the sustainability of the program and the active role of communities and governments in sustainable clean water management.

Village-Owned Enterprises (BUMDes) are business units that are jointly owned and managed by the village government and the local community. The establishment of BUMDES aims to exploit economic potential and improve the welfare of village communities. One of the BUMDes highlighted in this study is BUMDes Loh Jinawi which is located in Tunjungmuli Village, Karangmoncol District, Purbalingga Regency. In its development, Tunjungmuli Village is still faced with geographical challenges and inadequate infrastructure. BUMDes Loh Jinawi manages four main business units, namely Pertashop, Pamsimas, Markets, and innovations in the agricultural sector so that they can meet the basic needs of the community. Pertashop provides access to fuel, Pamsimas ensures clean water supply, Markets support local trade, and agricultural units increase food security and farmer incomes through sustainable practices. These initiatives have significantly improved the quality of life and economic opportunities for local residents, especially farmer groups. Through participatory management and community involvement, BUMDes Loh Jinawi has fostered a sense of belonging among residents while overcoming socio-economic challenges. The authors contributed by facilitating observations, workshops and mentoring to improve BUMDes operations. In a series of community service activities, it was found that optimizing the management of BUMDes Loh Jinawi can be done in two ways, namely assisting with management practices to increase access to basic services and empowering the surrounding community economically and socially.  This study provides a replicable model for sustainable rural development.
