Abstract

ABSTRAKProduktivitas dalam pekerjaan konstruksi merupakan ukuran penting untuk menilai sejauh mana sumber daya antara lain pekerja, material, peralatan, dan manajemen dimanfaatkan secara optimal dalam proses pelaksanaan proyek. Selain dipengaruhi oleh aspek teknis, produktivitas juga dipengaruhi oleh faktor-faktor sosial dan psikologis. Salah satu faktor yang ditinjau adalah pemberian reward atau penghargaan terhadap karyawan. Penelitian ini mengkaji pengaruh pemberian reward terhadap produktivitas tenaga kerja konstruksi, dengan mengambil studi kasus pada pekerjaan pembangunan pier di proyek Kereta Api Cepat Jakarta–Bandung. Dalam upaya mempercepat durasi pekerjaan, pihak pelaksana menerapkan strategi pemberian reward sebagai bentuk motivasi kerja. Hasil kajian menunjukkan bahwa reward memberikan dampak positif terhadap peningkatan produktivitas tenaga kerja. Dengan pemberian reward produktivitas tenaga kerja dalam pekerjaan pier meningkat dari 0,022 pier/hari menjadi 0,04 pier/hari. Selain itu, pemberian reward juga memunculkan pola kerja baru yang mengarah kepada usaha peningkatan produktivitas kerja seperti disiplin memulai kerja lebih pagi dan peningkatan semangat untuk bekerja lembur. Hasil penelitian ini menunjukkan pentingnya pendekatan manajerial yang tidak hanya fokus pada teknis pelaksanaan, tetapi juga memperhatikan aspek penghargaan terhadap tenaga kerja sebagai bagian dari strategi peningkatan kinerja proyek secara keseluruhan.Kata kunci: produktivitas, reward ABSTRACTProductivity in construction work is a crucial measure to assess how effectively resources such as worker, materials, equipment, and management are utilized during project implementation. In addition to being influenced by technical aspects, productivity is also affected by social and psychological factors. One of the factors examined in this study is the provision of reward or incentives to workers. This research investigates the effect of reward systems on the productivity of construction worker, using a case study of pier construction in the Jakarta–Bandung High-Speed Railway project. In an effort to accelerate project duration, the contractor implemented a reward strategy as a motivational approach. The findings indicate that rewards had a positive impact on worker productivity, increasing the rate from 0.022 piers/day to 0.04 piers/day. Additionally, the reward system encouraged new working patterns aimed at improving productivity, such as increased discipline to start work earlier and greater enthusiasm for working overtime. This study highlights the importance of managerial approaches that go beyond technical execution by incorporating recognition and motivation strategies as integral components in enhancing overall project performance.Keywords: productivity, reward

Abstract

In gravity-based water distribution systems in mountainous regions, excessive hydrostatic pressure—caused by significant elevation differences can lead to pipeline stress, leakage, or even bursts. To control this, pressure-reducing valves (PRVs), break-pressure tanks, or energy recovery systems like micro-hydropower turbines are strategically installed at key elevation drops. These methods ensure pressure stability, protect infrastructure, and can also enhance system efficiency and sustainability when excess pressure is harnessed for energy generation. This study examines technical strategies for controlling excessive hydrostatic pressure in gravity-based water distribution systems in mountainous regions, with a focus on the Cilongkrang system in Majalengka, Indonesia. With an elevation difference of over 950 meters between the spring and service zone, the system faces potential hydrostatic pressure exceeding 90 bar, far beyond the design limits of standard pipelines. The research compares two pressure control technologies Pressure Reducing Valves (PRV), and Break Pressure Tanks (BPT). By evaluating their hydraulic performance, operational practicality, lifecycle costs, and field applicability. The analysis utilizes topographic data, pressure modelling, and actual project cost estimates to quantify the effectiveness of each option. Results show that BPTs are more cost-effective and reliable for large elevation drops in rural areas with sufficient land, while PRVs are suitable for confined, urban installations requiring precision. This study contributes a practical framework for designing sustainable gravity-fed water supply systems in extreme topographic conditions.
