Abstract

Hydrometeorological disasters are disasters caused by damage to the system in the hydrological cycle, thereby affecting the stability of climate conditions and water reserves on the earth's surface. Hydrometeorological disasters include droughts, floods, storms, forest fires, landslides, cyclones, cold waves and heat waves. On December 6 2021 several areas in West Lombok Regency were affected by flooding caused by extreme weather. One of the areas affected is Lembah Sari Village, Batu Layar District, West Lombok Regency. From the geographical conditions of Lembah Sari Village, it has a high potential for hydrometeological disasters. For this reason, the Community Service Team for the Civil Engineering Study Program (Prodi) at Muhammadiyah University of Mataram carried out outreach related to hydrometeorological disaster mitigation in Lembah Sari Village, Batu Layar District, West Lombok Regency. The method used is counseling with material presentation sessions and question and answer discussions. The activity will be held on August 28 2023. The extension activity can run well and smoothly as seen from the enthusiasm of the people in listening to the presentation of the material which is then followed by a question and answer session.

Abstract

This study aims to analyzed the implementation of Occupational Safety and Health (OHS) procedure on construction projects in the Public Works, Spatial Planning and Housing Office of East Kalimantan Province, particularly in the Water Resources sector. The focus of this research is on comparing the level of OHS implementation between small and non-small construction companies. The method used in this research was a quantitative approach with questionnaire instruments, validity and reliability tests, and statistical analysis using the Chi-Square test and contingency coefficient. The results showed that there was a difference in the level of implementation of the OHS procedure between small and non-small construction companies, as well as a significant relationship between the company category and the level of compliance with the implementation of OHS. This research can be forms the basis for recommendations to improve the effectiveness of policies, quality of training, implementation of procedures, awareness raising and completeness of work safety facilities.

Abstract

Penelitian ini bertujuan untuk mengevaluasi pemanfaatan pasir besi dan pasir pantai sebagai substitusi sebagian agregat halus pada campuran Asphalt Concrete – Binder Course (AC-BC) serta menentukan proporsi optimum yang mampu memenuhi persyaratan kinerja menurut Spesifikasi Bina Marga 2018 Revisi 2. Pengujian laboratorium dilakukan menggunakan pasir besi dari Pantai Kerakat dan pasir pantai dari Pantai Malimbu, sedangkan agregat kasar dan abu batu diperoleh dari AMP setempat. Pengujian Marshall dilakukan dengan kadar aspal optimum sebesar 5,15% dengan parameter yang dianalisis meliputi stabilitas, kelelehan, Marshall Quotient, Void in Mineral Aggregate (VMA), Void in Mix (VIM), dan Void Filled with Bitumen (VFB). Hasil penelitian menunjukkan bahwa meskipun beberapa campuran tidak memenuhi kriteria VIM dan VFB, dua variasi 5% pasir besi + 5% pasir pantai dan 7,5% pasir besi + 2,5% pasir pantai menunjukkan keseimbangan interaksi antarbutir, interlock agregat yang baik, dan struktur internal yang stabil sehingga memenuhi seluruh spesifikasi yang dipersyaratkan. Secara ilmiah, pencapaian kinerja tersebut disebabkan oleh karakteristik pasir besi yang meningkatkan kerapatan struktur dan pasir pantai yang memperbaiki kemampuan kerja sehingga mencegah over compaction. Sebaliknya, campuran dengan dominasi pasir pantai menghasilkan rongga udara tinggi, sedangkan campuran dengan dominasi pasir besi menjadi terlalu rapat, keduanya menyebabkan ketidaksesuaian spesifikasi. Secara keseluruhan, penelitian ini membuktikan bahwa proporsi terkontrol dari kedua material lokal ini dapat dimanfaatkan secara efektif sebagai substitusi agregat halus dalam campuran AC-BC
