Abstract

Pulau Nusa Penida yang saat ini merupakan destinasi paling favorit di Kabupaten Klungkung. Desa Sakti merupakan salah satu desa yang terletak di Nusa Penida dengan keindahan pantai nya yang disebut Gamat Bay. Permasalahan yang ada di Desa Sakti berupa kesulitan akan pemenuhan air baku untuk kebutuha air sehari-hari serta daerah wisata Gamat Bay. Maka dari itu pengabdian masyarakat ini akan menganalisa konsep embung yang akan diterapkan pada Desa Sakti untuk. Data analisa menggunakan data hasil wawancara mengenai permasalahan yang terjadi di Desa Sakti serta melakukan pengambila data kontur pada rencana lokasi embung. Analisa perencanaan konsep embung menggunakan analisa hidrologi serta analisa kurva tampungan embung. Hasil analisa didapatkan lebar mercu embung sebesar 17,5 m dan debit banjir 71,35 m3/dt sehingga tinggi muka air (hd) sebesar 1,00 m dan tinggi embung sebesar 5 m. Kapasitas tampungan yang didapatkan untuk dua alternatif lokasi yaitu alternatif satu dengan lebar cross section sebesar 180 m didapatkan tampungan sebesar 0,14x106 m3. Sedangkan alternatif dua dengan lebar cross section sebesar 37.05 m tampungan yang didapatkan sebesar 0,05x106 m3.

Abstract

Desa Pempatan, Kecamatan Rendang, Karangasem menghadapi permasalahan serius terkait ketersediaan air irigasi akibat kondisi topografi berbukit dan ketergantungan tinggi pada curah hujan musiman. Sistem irigasi tradisional yang masih dilakukan secara manual menyebabkan pemborosan air, biaya operasional tinggi, dan produktivitas pertanian yang tidak stabil. Program pengabdian TIRTA (Teknologi IoT untuk Irigasi Terkendali dan Automasi) ini dikembangkan untuk memberikan solusi melalui penerapan sistem irigasi otomatis berbasis Internet of Things (IoT) yang memungkinkan pengaturan penyiraman melalui jadwal dinamis menggunakan Telegram Bot. Teknologi ini memanfaatkan ESP32 sebagai mikrokontroler utama, relay sebagai aktuator pompa, serta integrasi protokol MQTT untuk memastikan komunikasi yang ringan dan stabil. Hasil implementasi menunjukkan peningkatan efisiensi air, pengurangan beban kerja petani, serta peningkatan stabilitas produksi. Sistem ini terbukti menjadi solusi tepat guna yang mudah dioperasikan, hemat biaya, dan sesuai dengan kondisi infrastruktur pedesaan.

Abstract

The construction of health care facilities, such as Community Health Centers (Puskesmas), requires efficient cost planning given the limited local government budget. One approach to optimizing costs without reducing the building's function and quality is value engineering. This study aims to apply the value engineering method to the construction project for the UPTD Puskesmas III Building of the West Denpasar District Health Office to identify work items with potential for cost efficiency and to analyze the savings that can be achieved. The research method uses a case study approach with a value engineering work plan that includes the information stage, function analysis, creative stage, analysis stage, development stage, and recommendation stage. The analysis was carried out using breakdown cost analysis, cost-benefit ratio, life-cycle cost (LCC), and the Analytical Hierarchy Process (AHP). The results of the study indicate that work items such as floor slabs, doors and windows, ceramic floors and walls, and wall masonry and plastering have the greatest potential for value engineering. The implementation of the selected alternative resulted in a total cost savings of Rp1,308,373,475.75 or 7.67% of the total initial project cost. These results indicate that value engineering is effective in increasing construction cost efficiency without reducing the building's function or quality, making it suitable for application in health care facility construction projects.

Abstract

When planning a tall building structure, the deviation due to lateral forces is very important to be taken into account in the planning of tall building structures. To reduce the amount of deviation in the structure adding by special structural elements, as shear walls. With the shear wall, can increase the stiffness of the building structure and absorb large shear forces along with higher the building structure and lateral force on structure will not fully accepted by frame structure which will result a decrease in deviation. Guestwing 1 The Ritz Carlton Hottel located in South Kuta District, Badung Regency, Bali. This building has a height of 20.2 m consisting of 6 floors. Planning with 2 models: a) SRPMK Existing Modeling, b) Dual System Model. Material specifications and loading are the same, just different in addition of shear walls and reducing the dimensions the building. Based on the results the analysis of the two models, the largest inter-storey deviation value in the existing model X=52.014mm; Y=47.960mm and for the dual system model X=25.614mm; Y=26.026mm. From the results of deviation analysis on both models, can be concluded that with addition of shear walls, there is a decrease in deviation 63.27% in X direction and 68.18% in Y direction. The most significant decrease occurs in dimensions and reinforcement of column K1 from size 350x800mm with 22 D22 reinforcement to column 300x600mm with 18 D22 reinforcement, beam B3 250x450mm for support area 17 D13 and field area 10 D13 to beam 250x400mm with the number of support reinforcement 11 D13, and the number of field reinforcement 7 D13. From the results of this planning can be used as a consideration for the construction of the next building for the use of shear walls in the structure.

Abstract

This study was conducted to analyze the performance of multi-story building structures using a flat slab system with drop panels, both in single and adjacent configurations. The research was motivated by Indonesia’s high seismic activity and the growing need for efficient and easily constructed structural systems that also provide aesthetic benefits. The main objective was to evaluate and compare the lateral displacement behavior of both structural models and assess their compliance with the drift limits specified in SNI 1726:2019. The analysis was performed through numerical modeling using ETABS software, with load combinations following SNI 1727:2020 for minimum design loads and SNI 2847:2019 for reinforced concrete strength provisions. The structural models consisted of a 200 mm thick flat slab and a 300 mm thick drop panel, supported by beams and columns designed to meet flexural and shear capacity requirements. The analysis results indicated that the maximum displacement was 34.584 mm in the X direction and 12.832 mm in the Y direction, both within the allowable drift limits. The adjacent building model exhibited average lateral displacements 1.25 times smaller in the X direction and 3.75 times smaller in the Y direction compared to the single structure, indicating a stiffness improvement due to inter-building interaction. All structural components, including the 7.6-meter-deep pile foundation, satisfied the strength and stability criteria. It was concluded that the flat slab system with drop panels is structurally efficient and seismically safe, providing a reliable alternative for building design in earthquake-prone regions.
