Abstract

Proyek konstruksi memiliki keterkaitan dengan tujuan pembangunan berkelanjutan (SDGs) melalui penerapan konstruksi berkelanjutan yang menekankan efisiensi sumber daya, termasuk material sebagai komponen biaya terbesar. Material konstruksi menyumbang sekitar 60–80% dari total biaya proyek, sehingga perubahan harga material menjadi faktor krusial yang dapat memicu pembengkakan biaya dan mengganggu keberlanjutan pelaksanaan proyek. Salah satu penyebab meningkatnya biaya material adalah ketidaktepatan dalam estimasi dan perencanaan anggaran, terutama ketika terjadi fluktuasi harga yang dipengaruhi kondisi pasar dan rantai pasok. Penelitian ini bertujuan untuk mengidentifikasi dan memprioritaskan faktor-faktor yang paling mempengaruhi fluktuasi harga material konstruksi, khususnya pada proyek di wilayah Bali Timur yang memiliki tantangan geografis dan logistik tersendiri. Metode Analytical Hierarchy Process (AHP) digunakan untuk memperoleh bobot prioritas berdasarkan penilaian para praktisi konstruksi. Hasil penelitian menunjukkan bahwa tujuh faktor utama penyebab fluktuasi harga material adalah persediaan material (19,2%), permintaan pasar (15,2%), perubahan harga BBM (15,1%), lokasi proyek (14,7%), kebijakan pemerintah (12,9%), inflasi (12,7%), dan biaya produksi (10,1%). Penelitian ini berkontribusi dalam menyediakan dasar pertimbangan strategis bagi kontraktor dan pemangku kebijakan untuk merumuskan strategi pengendalian biaya dan meningkatkan resiliensi rantai pasok material di Bali Timur.

Abstract

Drought poses a significant threat to water supply in regions like Kulon Progo, Indonesia. Seasonal water shortages lead to agricultural losses and increased disaster vulnerability. This study aims to improve groundwater exploration method for drought mitigation by analyzing the correlation between lineament density and groundwater using a dataset of 127 observations from Samigaluh and Kalibawang subdistricts using Pearson Correlation. The research uncovers a non-linear threshold at 4 km/km². Below the threshold, groundwater occurrence increases with density (r = 0.949), shows increasing infiltration. But above the threshold, occurrence decreases (r = -1.000), suggesting over-fracturing reduces storability. Maximum depths follow a similar pattern (r = 0.883 below, r = -1.000 above). These findings challenge conventional scoring methods in groundwater potential zoning, which often assume a linear positive relationship with lineament density. The study provides a novel framework for targeted exploration, prioritizing moderate-density zones to mitigate drought impacts and build resilience against climate-induced disasters.
