Abstract

Desa Gogik terdapat tempat wisata air terjun yang mengalami kesulitan infrastruktur pembangunan sistem kelistrikan pada penerangan jalan. Tujuan tugas akhir adalah Membuat turbin pelton dari pipa PVC berdasarkan potensi yang ada. Mengkaji secara eksperimental kinerja PLTMH untuk pengisian aki. Pengujian efisiensi dilakukan tiga kali yaitu dengan variasi beban dengan beberapa debit konstan. Hasil dari pengujian yaitu penggunaan PLTMH turbin pelton dari pipa PVC. Nilai efisiensi tertinggi pada debit 0,0020419 m3 /s yaitu sebesar 20,73%, pada debit 0,0024892 m3 /s yaitu sebesar 69,61% dan pada debit 0,0029339 m3 /s yaitu sebesar 91,88% . Hal ini membuktikan bahwa turbin pelton ini paling cocok dioperasikan pada debit 0,0029339 m3 /s. Energi yang disimpan di dalam aki sebesar 1.236 VAH sedangkan kebutuhan energi di Desa Gogik sebesar 640 VAH, maka energi tersisa sebesar 596 VAH,untuk penambahan lampu jalan pada dua titik sebesar 520 VAH jadi energi yang tersisa adalah 76 VAH.

Abstract

Hypertension is a condition where there is an abnormal and continuous increase in blood pressure caused by one or several risk factors that do not work as they should in maintaining normal blood pressure (Majid, 2018). The signs and symptoms in hypertensive patients are the onset of pain. due to increased blood pressure. The purpose of this writing is to find out and provide nursing care to Mr. T With Cardiovascular System Disorders: Hypertension in Kalibuntu Village Rt 02 Rw 02 Losari District, Brebes Regency in accordance with nursing standards. The methods used are descriptive methods and data collection methods. From the case review, it was found that Mr. T complains of pain. There were two diagnoses found, namely acute pain and knowledge deficit. Interventions are prepared based on the theory of SDKI, SLKI and SIKI as well as on the client's condition and can be implemented.

Abstract

Studi ini melakukan analisis komparatif performa hidrodinamika pipa konvensional dan pipa spiral untuk aliran fluida non-Newtonian dalam sistem perpipaan. Metodologi meliputi pemodelan geometri dengan SolidWorks dan simulasi Komputasi Dinamika Fluida (CFD) menggunakan ANSYS Fluent untuk evaluasi penurunan tekanan. Validasi model numerik terhadap data eksperimen terdahulu mengkonfirmasi kemampuannya dalam memprediksi perilaku rheologi fluida. Hasil penelitian menunjukkan bahwa pipa spiral secara konsisten meminimalkan penurunan tekanan dibandingkan pipa konvensional pada kondisi horizontal, suatu keuntungan yang dikaitkan dengan peningkatan distribusi partikel dan reduksi gesekan akibat secondary flow. Meskipun kemiringan pipa 6,76o meningkatkan pressure drop secara keseluruhan, pipa spiral mempertahankan keunggulannya di sebagian besar skenario. Namun, observasi menunjukkan adanya titik di mana pressure drop pipa spiral dapat mendekati atau melampaui pipa konvensional pada kecepatan tinggi dan fraksi volume tertentu, menandakan adanya dinamika multi-parameter yang kompleks. Temuan ini penting untuk perancangan dan optimalisasi sistem perpipaan fluida non-Newtonian di sektor teknik perkapalan.

Abstract

This study examines the role of the Village Consultative Body (BPD) in the formation of Mendalo Indah Village Regulation Number 02 of 2018 regarding Waste Collection, referring to Minister of Home Affairs Regulation Number 111 of 2014. Using an empirical juridical approach with a qualitative research method, the study was conducted in Mendalo Indah Village, Muaro Jambi Regency, Jambi Province. Data were collected through participatory observation, in-depth interviews with key stakeholders (including the Village Head, BPD Chair, and community leaders), and documentation. The findings indicate that while the BPD's role in forming village regulations is generally less than optimal, it has a more active role during the discussion and finalization of the draft regulations. However, the initial drafting and proposing stages are often initiated by the Village Head, with limited proactive involvement from the BPD. Key challenges identified include inadequate BPD human resources, limited understanding of their duties, and poor communication and coordination between the BPD, the Village Government, and other stakeholders. The study concludes that improving the BPD’s capacity, knowledge, and collaboration is essential for more effective participation in village regulation formation.
