Abstract

Kegiatan Pengabdian kepada Masyarakat (PkM) ini bertujuan untuk meningkatkan pemahaman dan kesadaran peserta terhadap pentingnya sistem Rain Water Harvesting (RWH) sebagai solusi konservasi sumber daya air bersih di lingkungan Pesantren Quantum, Bekasi. Metode yang digunakan adalah sosialisasi melalui penyampaian materi edukatif yang interaktif, bertujuan memberikan pengetahuan dasar tentang konsep, manfaat, dan potensi penerapan RWH. Evaluasi keberhasilan program dilakukan dengan menggunakan instrumen pre-test dan post-test untuk mengukur peningkatan pengetahuan peserta, observasi partisipasi, serta diskusi kelompok terarah untuk menggali persepsi dan komitmen peserta. Lima indikator keberhasilan yang diukur meliputi tingkat kehadiran, peningkatan pemahaman konsep RWH, kesadaran terhadap manfaat konservasi air, kesiapan menerima penerapan sistem, dan kesadaran kolektif dalam pengelolaan air hujan. Hasil evaluasi menunjukkan peningkatan pemahaman peserta dari 30% pada pre-test menjadi 85% pada post-test, dengan tingkat partisipasi mencapai 92%. Sebanyak 87% peserta menyatakan dukungannya terhadap penerapan sistem RWH di lingkungan pesantren. Temuan ini mengindikasikan bahwa metode sosialisasi efektif untuk membangun kesadaran awal dan motivasi masyarakat dalam konservasi air berbasis komunitas.

Abstract

the dynamics of the building materials market and labor costs. Therefore, a constantly updated reference is needed to ensure accurate and efficient project cost estimates. One such reference is the Work Unit Price Analysis (AHSP) which is released by the government periodically. This study aims to analyze and compare the Cost Budget Plan (RAB) value for structural work on the Kampi Sunter Hotel construction project based on the Work Unit Price Analysis (AHSP) versions 2024 and 2025. The method used is a quantitative approach through cost estimation calculations using both versions of the AHSP. The results show that the total cost of structural work based on the 2024 AHSP is Rp15,384,577,550, while based on the 2025 AHSP it is Rp13,830,592,539. There is a difference of Rp1,553,985,011 or a decrease of approximately 10.1% in the 2025 AHSP. This decrease is caused by changes in the unit price of materials, one of which is the price of Ready Mix Concrete K300 which decreased from Rp1,048,722.00 (2024) to Rp931,683.00 (2025). Therefore, it is important for project planners to always update the AHSP reference used to match the applicable year to be more relevant.

Abstract

Mechanical earthmoving is a critical component in construction project execution that significantly affects time and cost efficiency. This study analyzes the productivity of a combined heavy equipment system consisting of a Komatsu PC78US excavator and a Mitsubishi Canter FE dump truck at the B-Quik Veteran Auto Workshop Construction Project in South Jakarta, with an excavation volume of 1,485.91 m³ and a hauling distance of 10 km. The existing condition, using one excavator and one dump truck, resulted in a productivity imbalance that extended project completion to 32 days, twice the initial 16-day target. By optimizing the equipment combination through the addition of one dump truck, total productivity increased from 18 m³/hour to 24.01 m³/hour. Results show that the project can be completed within 16 working days (128 hours) with a cost saving of IDR 24,005,120 compared to the existing condition. This study demonstrates that synchronization between excavation and hauling equipment is the key factor in heavy equipment management optimization.
