Abstract

Seamless steel pipes in oil and gas pipeline applications will provide quite high pressure, so the welding process is important in ensuring pipe safety. This study aims to analyze the hardness, hydrogen test and welding size of seamless steel pipes that undergo post weld heat treatment (PWHT) process. The pipe diameter dimension is 6 inches with API 5L Gr.X65 PSL2 type. The experimental method begins with the PWHT process by heating to a temperature of 625 ° C with a holding time of 1 hour 10 minutes then slowly cooled with a cooling rate of 154 ° C / hour. The specimens that underwent PWHT were then analyzed for hardness, hydrogen test and welding size simulation. The hardness results decreased after PWHT at all basic metal, HAZ and center of weld positions. Position 0 ° ranges from 126-174 HRB, position 120 ° produces a value of 122 - 143 HRB and position 270 ° has a value of 133-154 HRB. The decrease in hardness occurs due to the tempering process which reduces residual stress. The pressure generated in the hydrogen test does not exceed the yield strength of the API 5L Gr.X65 PSL2 pipe material, which is 65,300 psi. The maximum weld size simulation results are produced with a value of 6,448 mm and a minimum value of 1,572 mm. The maximum value is used as a reference in welding to produce a safe connection.

Abstract

The enhancement of local resources through agrotourism presents significant opportunities for economic growth, social benefits, and environmental sustainability in rural communities. This study explores strategic approaches to community empowerment in the development of agrotourism villages within Kuningan Regency, West Java, an area rich in agricultural potential. A qualitative case study method was adopted, gathering data through observations, in-depth interviews, and focus group discussions (FGD). The findings underscore that agrotourism village development requires an integrated approach, focusing on robust governance, active community participation, innovation, and cross-sector collaboration to efficiently manage and promote tourism destinations. The study highlights the critical role of government policy and budgetary support in establishing programs that leverage local agricultural strengths, empowering communities to participate actively in sustainable tourism. By employing a comprehensive, long-term development model, agrotourism can be effectively harnessed to yield both economic and social value for local communities, while also prioritizing environmental conservation. This research provides valuable insights into how structured community empowerment and strategic collaboration can unlock the full potential of agrotourism as a sustainable development pathway for rural regions.Peningkatan sumber daya lokal melalui agrowisata menghadirkan peluang signifikan untuk pertumbuhan ekonomi, manfaat sosial, dan keberlanjutan lingkungan di komunitas pedesaan. Studi ini mengeksplorasi pendekatan strategis dalam pemberdayaan masyarakat untuk pengembangan desa agrowisata di Kabupaten Kuningan, Jawa Barat, yang kaya akan potensi pertanian. Metode studi kasus kualitatif diterapkan, dengan pengumpulan data melalui observasi, wawancara mendalam, dan diskusi kelompok terarah (FGD). Hasil penelitian menekankan bahwa pengembangan desa agrowisata membutuhkan pendekatan terintegrasi yang berfokus pada tata kelola yang kuat, partisipasi aktif masyarakat, inovasi, serta kolaborasi lintas sektor untuk mengelola dan mempromosikan destinasi wisata secara efisien. Studi ini menyoroti peran penting dukungan kebijakan dan anggaran pemerintah dalam membentuk program-program yang memanfaatkan kekuatan pertanian lokal, memberdayakan masyarakat untuk berpartisipasi aktif dalam pariwisata berkelanjutan. Dengan menerapkan model pengembangan yang menyeluruh dan jangka panjang, potensi agrowisata dapat dimanfaatkan secara efektif untuk memberikan nilai ekonomi dan sosial bagi masyarakat lokal, sambil tetap memprioritaskan pelestarian lingkungan. Penelitian ini memberikan wawasan berharga tentang bagaimana pemberdayaan masyarakat yang terstruktur dan kolaborasi strategis dapat membuka potensi penuh agrowisata sebagai jalur pembangunan berkelanjutan bagi wilayah pedesaan.

Abstract

This research is about the E-Readiness of the Berau Regency Population and Civil Registration Service in public services using the Si Penyu Beramal application. The research method used is qualitative with a descriptive approach, involving observation, interviews and documentation studies. The results show that electronic readiness is considered sufficient, with several factors influencing it, such as telecommunications infrastructure, connectivity, use of information technology, adequate budget, governing laws, and paradigm changes by employees. The main obstacle is the shift from offline to online systems and the failure to achieve three performance targets. Suggestions include improving infrastructure, human resource training, efficient budget management, and outreach to the community.
