Abstract

The study of water balance is an analysis of the equilibrium between water demand (demand system) and water availability (supply system). Current conditions show that the water balance tends to become increasingly critical, leading to conflicts of interest in water use. Therefore, optimizing water allocation in a watershed (DAS) is necessary by considering water users and the regulations applicable within the administrative area where the watershed is located. The location of the water balance analysis research is in the Barito River Basin, which consists of the Barito Watershed, Kapuas Watershed, Maluka Watershed, and Tabanio Watershed. In this study, the Barito Watershed is the largest watershed within the Barito River Basin, crossing two provinces, namely Central Kalimantan Province and South Kalimantan Province. The aim of this research is to provide water balance calculations that can serve as a basis for developing water allocation concepts in the form of an annual water supply plan. The data used in the water balance analysis include spatial data, hydrological data, and walkthrough implementation data. The results of the water allocation modeling provide an overview of the extent to which water demand is met under existing conditions and can serve as a consideration if there is an increase in water utilization rates for each user in the future.

Abstract

Open-pit coal mining temporarily alters natural landscapes, resulting in degraded overburden dumps and the formation of pit lakes. In Indonesia, post-mining landforms must undergo reclamation to support sustainable land use. This study evaluates the hydrological capacity of a reclaimed area functioning as the catchment for the Paringin pit lake by applying two hydrological models: the National Rural Electric Cooperative Association (NRECA) and the F.J. Mock model. Using an integrated approach that combines remote sensing, GIS-based spatial analysis, and field-based observations—including meteorological data, real-time inflow monitoring using aerial sensors, and Total Suspended Solids (TSS) measurement—both models successfully simulated monthly inflow and showed good agreement with field observations. Under a tropical climate with over 3,000 mm of annual rainfall and evaporation exceeding 1,000 mm, the catchment-to-lake area ratio of 6.4:1 was found to support sustainable inflow volumes ranging from 0.078 to 0.103 m³/s throughout the year. Although the estimated erosion rate of 3.51 t/ha/year remains within acceptable limits, average TSS levels (89.13 mg/L) exceeded the regulatory threshold of 50 mg/L for raw water supply and aquaculture use. The results affirm the effectiveness of the NRECA and F.J. Mock model in supporting post-mining water management where monitoring data are scarce. This study contributes to the growing need for hydrological connectivity assessment in post-mining landscapes and supports improved planning and sustainable management of pit lakes as integrated components of degraded post-mining land.

Abstract

Erosi adalah peristiwa perpindahan atau terangkutnya tanah atau bagian-bagian tanah dari suatu tempat ke tempat lain oleh media alami. Pada peristiwa erosi, tanah atau bagian-bagian tanah pada suatu tempat terkikis dan terangkut yang kemudian diendapkan di tempat lain. Erosi mengakibatkan sebagian besar lapisan tanah hilang, besarnya erosi yang terjadi juga menunjukkan betapa kritisnya tanah tersebut. Tujuan dari penelitian ini adalah untuk mengetahui kondisi serta tingkat laju erosi tanah pada Sub-Sub DAS Riam Kanan terutama di wilayah Rantau Balai pada tahun 2024. Metode penelitian yang digunakan berupa model Equation of Revised Universal Soil Loss (RUSLE) dengan data yang diolah menggunakan javascript pada platform Google Earth Engine. Metode RUSLE dapat memberikan hasil kehilangan tanah yang signifikan dalam menganalisis aliran permukaan. Persamaan RUSLE yang digunakan menggunakan faktor erosivitas hujan (R), faktor erodibilitas tanah (K), faktor Panjang dan kemiringan lereng (S), faktor pengelolaan tanaman (C), serta faktor tindakan konservasi (P). Hasil analisis rata-rata laju erosi yaitu sebesar 6,0849 Ton/Ha/Tahun dikategorikan sebagai erosi kelas sangat ringan. Metode analisis spasial menggunakan model RUSLE dan Google Earth Engine terbukti efektif dalam memberikan pemahaman yang lebih baik tentang potensi erosi tanah di wilayah studi.

Abstract

Swamp land in Terantang Village, Barito Kuala Regency, South Kalimantan has the potential to be utilized if managed optimally. Sour swamp land needs to be managed by the reclamation process. However, the high accumulation of toxic iron (Fe) becomes an obstacle in optimizing the reclamation process. The two-way flow system with the help of tidal ponds in the reclamation channel used still needs further evaluation to find out how effective the washing of toxic materials is. The main factors that influence the most are tidal events and partial pond function. The use of Environmental Fluids Dynamic Code (EFDC) software with simulation based on the data obtained is estimated to be able to solve the existing problems. This research was conducted in primary, secondary and tertiary reclamation channels with several stages. The first stage is to identify the hydrodynamic conditions and water quality in the Terantang unit reclamation channel. The second stage is the preparation and testing of the model. The second stage is the preparation and testing of the model. The last stage is model simulation on flow pattern, water age, accumulation of iron (Fe) concentration and accumulation of TSS concentration in 3 scenarios. The scenarios consist of simulating the hydrodynamic aspects of current movement and water age and 2 simulation scenarios of the water quality aspect on the accumulation of iron (Fe) concentration and TSS concentration by paying attention to the partition coefficient and without the partition coefficient. Simulations were carried out using the primary, secondary and 5 tertiary channel representative model data. The simulation results show that the application of channel tidal forces and partial pool utilization is still not running well. This happened based on the simulation results on the hydrodynamic and water quality aspects, showing that the water washing process still reached 60% with the water age reaching 3 days. The tidal force of the water is not able to reach the end of the channel and the tide pattern has not yet reached the end of the channel but has receded.
