Opis:: There are several springs with the large discharge around the Watuputih Karst Hills area that playing a crucial role in supplying water for both domestic and irrigation needs. The springs are located in the fault and fold zones of the Rembang anticlinorium system. This study was designed to determine the characteristics of karst aquifers from one year of monthly spatio-temporal data on discharge parameters and physico-chemical properties (temperature, pH, EC, Ca²⁺, Mg²⁺, HCO_3–) of the four major springs, namely Brubulan Tahunan, Sumbersemen, Brubulan Pesucen, and Sendang Sayuran. It used statistical calculations to characterize spring discharge and hydrochemical variations, as well as bivariate correlation analysis and flow-duration curve (FDC). The variability index (I_v), variability (V), and spring coefficient of variation parameters (SCVP) classified Brubulan Tahunan and Sumbersemen as springs producing stable, fairly constant discharge with low variations but characterized Brubulan Pesucen as having unstable, varying discharge with moderate variations. The results showed gently sloping hydrograph, low variations in discharge and hydrochemical properties, a relatively prolonged response of discharge and CO₂-H₂O-CaCO₃ interaction to rainfall, and slope changes in the FDC. In other terms, although the springs are controlled by faults and folds, they have diffuse groundwater storage system in the form of densely fractured and porous media. These findings also indicate a less developed interconnected conduit, although Brubulan Pesucen is relatively more developed than Sumbersemen and Brubulan Tahunan. The geological structure and hydraulic gradient formed between the groundwater recharge and discharge areas are proven to control the amount of spring discharge actively.

Opis:: Domestic wastewater in Gampong Garot, Aceh Besar Regency, Aceh Province, Indonesia is directly discharged to the Daroy River without any treatment process. Domestic wastewater from Gampong Garot has been one of the contributors to microplastics contamination in the Daroy River. The microplastics (MPs) contained in domestic wastewater might come from used soaps and detergent products, as well as the scouring of clothes during washing. Thus, this study aims to investigate the abundance of MPs in domestic wastewater in Gampong Garot. The sampling points were determined based on purposive sampling, with samples taken at the end of the main pipe that directly leads to the Daroy River. Organics in domestic wastewater were removed using 30% H2O2 liquid through a digestion process at a temperature of 75°C. MPs characteristics such as size, shape, and colour were visually analysed using a light binocular microscope at 100× magnification, while the polymer type was analysed using Fourier transform infrared (FTIR) analysis. The concentration of MPs in domestic wastewater in Gampong Garot was 30.238 ±1.228 particles∙(100 cm)-3 sample. The most common sizes of MPs were found to be in the range of 1,001-5,000 μm, while the dominant colour and shape were transparent and fibre-like. Polyester (PES) was the most detected type of MPs. These findings highlight the need for wastewater treatment before discharge into aquatic bodies.

Opis:: The objective of this study is to examine the implementation of a combined scheme involving payment environment services (PES) and non-payment environment services (non-PES) in the management of the Cidanau River Basin. This study used exploratory research to analyse the structure and mechanism of PES and non-PES schemes for the governance system. The Cidanau Watershed governance is a pioneer in sustainable integrated water resources management in Indonesia and has persisted until the present time. The governance of the Cidanau Watershed is dynamic, resilient, and evolving in response to various changes in social and ecological systems. A bridging organisation like the Cidanau Watershed Communication Forum (Ind.: Forum Komunikasi DAS Cidanau - FKDC) requires legal standing to be visible and gain the trust of the public, especially when implementing a PES approach like the Cidanau River Basin, where service buyers utilise non-direct payment mechanisms. The challenging aspect of developing a PES scheme is empowering knowledge regarding the importance of soil and water preservation among upstream communities, particularly in developing countries like Indonesia, where upstream communities are predominantly composed of low-income farmers whose livelihoods depend on nature. The non-PES scheme represents the government’s mandatory responsibility, whereas the PES scheme presents public participation in active collaboration through the FKDC as an ad hoc institution. A combination of the non-PES and PES scheme approach can serve as a model and reference for similar river basin governance frameworks. Further research is needed regarding social networks and institutional development of sustainable watershed governance in the Cidanau River Basin.

Opis:: This study aims to utilise Climate Hazards Group Infrared Precipitation with Stations (CHIRPS) data and Standardised Precipitation Index (SPI) method to assess agricultural drought in West Papua, Indonesia. The data used in this study is monthly CHIRPS data acquired from 1996 to 2019, daily precipitation data recorded from 1996 to 2019 from the five climatological stations in West Papua, Indonesia located at Sorong, Fakfak, Kaimana, Manokwari, and South Manokwari. 3-month SPI or quarterly SPI are used to assess agricultural drought, i.e., SPI January-March, SPI February-April, SPI March-May, SPI April-June, SPI May-July, SPI June-August, SPI July-September, SPI August-October, SPI September-November, and SPI October-December. The results showed that in 2019 agricultural drought in West Papua was moderately wet to severely dry. The most severely dry occurred in September-December periods. Generally, CHIRPS data and SPI methods have an acceptable accuracy in generating drought information in West Papua with an accuracy of 53% compared with climate data analysis. Besides, the SPI from CHIRPS data processing has a moderate correlation with climate data analysis with an average R2= 0.51.

Opis:: The fostering and empowerment of water user associations (WUAs) has been regulated by the Minister of Agriculture since 2012. However, the implementation of this guideline varies. Some water user associations have achieved improvement, while some others have not. This study discusses how a WUA in the villages that use Bengawan Solo River water has successfully managed the irrigation. One of the factors leading to the success of this WUA is the stakeholder engagement in the agricultural irrigation management and farm business. This study was conducted from June 2016 to June 2017 by employing a qualitative approach. It aimed to identify and understand the stakeholder engagement in agricultural irrigation management by: 1) conducting an analysis on stakeholder power and interest indices, 2) mapping the positions, responsibilities, and obligations of stakeholders, and 3) identifying the stakeholder engagement in agricultural irrigation management. The research results are as follows: a) the analysis using Likert scale showed that the power index reached a value of 0.76, while the interest index reached a value of 0.78; b) the mapping of internal stakeholders, especially the responsibilities and obligations, has been regulated under the Articles of Incorporation of WUAs and obligations of external stakeholders, especially the government in making government regulations, irrigation infrastructure support, and flood prevention; c) cooperation of the stakeholders has an important role in the agricultural irrigation management and in solving the problems faced by WUAs.
Rozbudowa i wzmacnianie stowarzyszeń użytkowników wód jest regulowane przez Ministerstwo Rolnictwa Indonezji od 2012 r. Wdrażanie jego zaleceń przybiera jednak różną postać. Niektóre stowarzyszenia osiągnęły sukces, inne nie. W niniejszej publikacji opisano, w jaki sposób omawiane stowarzyszenia we wsiach, które korzystają z wody rzeki Bengawan Solo osiągnęły sukces w zarządzaniu nawodnieniami. Jednym ze źródeł sukcesu jest zaangażowanie udziałowców w rolnicze zarządzanie nawodnieniami i w produkcję rolniczą. Badania prowadzono od czerwca 2016 do czerwca 2017 r. stosując podejście jakościowe. Celem było zidentyfikowanie i zrozumienie zaangażowania interesariuszy w zarządzanie nawodnieniami poprzez: 1) przeprowadzenie analizy siły wpływu i poziomu zainteresowania interesariuszy, 2) zmapowanie pozycji, odpowiedzialności i zobowiązań interesariuszy oraz 3) zidentyfikowanie zaangażowania interesariuszy w zarządzanie rolniczymi nawodnieniami. Na podstawie analizy z wykorzystaniem skali Likerta stwierdzono, że siła wpływu interesariuszy wynosiła 0,76, a poziom zainteresowania – 0,78. Mapowanie wewnętrznych interesariuszy, w szczególności odpowiedzialności i zobowiązania, są regulowane artykułami o włączeniu stowarzyszeń, a zobowiązania zewnętrznych interesariuszy, głównie rządu; polegają na tworzeniu uregulowań prawnych, wsparciu infrastruktury nawodnieniowej i ochronie przeciwpowodziowej. Współpraca interesariuszy odgrywa znaczącą rolę w zarządzaniu nawodnieniami rolniczymi i w rozwiązywaniu problemów, które stają przed stowarzyszeniami użytkowników wód.
