Ir. H. Juanda 193, Bandung, Indonesia Komunikasi Penulis, Telp: +08122103205; email: [email protected] Naskah ini diterima pada 27 Desember 2017; revisi pada 3 Februari 2018; disetujui untuk dipublikasikan pada 19 Februari 2018 ABSTRACT Water security is the community's ability to maintain sustainability in meeting water demands for various purposes and managing water-related disasters. The score of Asian countries water security indicator has been formulated and calculated by the Asian Development Bank (ADB). However water security at the river basin level, including irrigation water security, has not been assessed. Like other Asian countries, irrigation in Indonesia is the largest water user, therefore irrigation water security plays important role in water resources management. This paper formulates and calculates the water security for irrigation in all river basins in Indonesia. The computation method is adopted from ADB, and developed according to the conditions of data availability and characteristics of river basins in Indonesia, under the assumption of homogeneity within river basin. It is concluded that the irrigation water security in the river basin in Indonesia is generally in "medium" condition. The "very bad" condition occurs only in Ciliwung-Cisadane and Progo- Opak-Serang river basins. The "bad" conditions include the Bangka, Belitung, Cidanau-Ciujung-Cidurian, Ciliman- Cibungur, Bali-Penida and Lombok river basins. Measures to improve irrigation water security are developing and improving performance of irrigation networks, improve reliability of water supplies by constructing reservoirs and ponds, and reducing water stress with water savings.

Martinus Dwi Marianto July 1995 ABSTRACT Surrealist painting flourished in Yogyakarta around the middle of the 1980s to early 1990s. It became popular amongst art students in Yogyakarta, and formed a significant style of painting which generally is characterised by the use of casual juxtapositions of disparate ideas and subjects resulting in absurd, startling, and sometimes disturbing images. In this thesis, Yogyakartan Surrealism is seen as the expression in painting of various social, cultural, and economic developments taking place rapidly and simultaneously in Yogyakarta's urban landscape.

Diversity and longitudinal distribution of freshwater fish in Klawing River, Central Java, Indonesia. Biodiversitas 19: 85-92. The aims of this study were to evaluate the diversity and longitudinal distribution of fish in Klawing River, Purbalingga (Central Java). The survey was performed using a clustered random- sampling technique. The river was divided into upstream, midstream and downstream regions. Species diversity was measured as the number of species, and the longitudinal distribution was assessed by determining the fish species present in each of the three regions. Eighteen fish species of eleven families were identified in the Klawing River: Cyprinidae, Bagridae, Mastacembelidae, Anabantidae, Cichlidae, Channidae, Eleotrididae, Beleontinidae, Osphronemidae, Poecilidae, and Siluridae. Cyprinidae exhibited the highest number of species (six), followed by Bagridae and Cichlidae (two species each). The other families were represented by one species each. A single cluster analysis showed that the upstream population had a similarity of 78% and 50% with the midstream and downstream populations, respectively. Species and family diversities were higher in the midstream populations than in the upstream and downstream populations.

The paper aims to determine the condition of Parangwedang as hot spring source in Parangtritis, Bantul, Yogyakarta and provide a guidance to develop Parangwedang as one of tourism destinations by controlling geological factor. The study is limited to examining the physical condition in the form of color, turbidity, odor, temperature and chemical condition (pH), compositions of calcium (Ca), sodium (Na), silica (SiO2), magnesium (Mg), bicarbonate (HCO3), sulfate (SO4) and chloride (Cl) and water source debits of Parangwedang hot springs as part of geohydrology research. The methodology used in the paper is divided into three steps. Firstly, the methodology was based on orientation and survey location. Then, it examined mapping the hot water temperature distribution. Lastly, it was implementing laboratory analysis of rocks and water. As a result, the paper portrays that there are potential water of hot of spring which meets the standards as clean water and the heat capacity can be utilized to support as geological tourism at Parangwedang, Bantul, Yogyakarta, Indonesia. 1 Introduction C and it can be used for baths and hot tubs.

Manusiwa, 1Aniek Prasetyaningsih 1 Faculty of Biotechnology, Duta Wacana Christian University, Jl. Dr. Wahidin Sudirohusodo, Yogyakarta, Indonesia; 2 Department of Fisheries, Faculty of Agriculture, Gadjah Mada University, Yogyakarta, Indonesia. Corresponding author: Djumanto, [email protected] Abstract. The ecological, biological and economical role of the Opak River's downstream is crucial for the people in the Bantul Regency area. Several home leather industries use the Opak River to dispose liquid waste, affecting water quality and aquatic biota. This study aimed to determine the concentration of chromium (Cr) in the Opak River ecosystem and fish. Sampling was carried out in February, April, and July 2020, in six locations, covering water, sediment and fish samples. The Cr concentration was measured for each sample using the atomic absorption spectrometer (AAS) method. The highest Cr concentration was found in Osteochilus vittatus (0.8489 mg kg-1), followed by the sediment samples (0.7125 mg kg-1), Oreochromis niloticus (0.3799 mg kg-1) and the water samples (0.01889 mg kg-1). The concentration of chromium in fish is still below the toxicity threshold for the biota and environmental health. The chromium concentration tends to increase according to the trophic level. Key Words: home industry, heavy metals, liquid waste. Introduction. Opak River is one of the rivers located in the east of the Yogyakarta Special Region, which has a flow length of approximately 65 km and a river basin area of 1,398.18 km2. The upstream part of the Opak River is located on the slopes of Mount Merapi in Cangkringan District, Sleman Regency.

The sustainability of the river ecosystem is necessary so that water River School availability can be maintained over time both in quantity and quality. Attention Empowerment to community behavior is the main target to guarantee the conservation of river water. River pollutants are increasing in quantity due to both domestic and production activities. Community empowerment aspect should always be improved especially in taking care of maintenance and utilization sustainability of the river for human life in particular and ecosystem in general. Tegaltirto Village which is crossed by the Opak River is very important to be preserved especially in proper river management. Community service in the form of institutional development of river school is needed. The scheme is appropriate to educate, assist, and initiate a proper and sustainable community empowerment forum. The research methods in the empowerment of a river school institution are focused on the participatory empowerment aspect. Data collection was done through interviews, documentation, and focus group discussions.

Wijaya2 & Sunarto3 1Department of Civil Engineering, Islamic University of Indonesia, Indonesia 2Former Student of Earthquake Engineering Management Master Program, Indonesia 3Department of Geography, Gadjah Mada University, Indonesia Abstract The 27th May 2006 Yogyakarta earthquake caused more than 5500 casualties and hundreds of thousands of non-engineered buildings collapsed. It is necessary to investigate the seismic intensity, ground acceleration and building damage index. Direct site investigations to collect the severity distribution of objects, humans and environments have been done. The result of the investigation shows that in general isoseismic lines are in-line with Opak fault, the proposed attenuation relationship for seismic intensity and horizontal ground accelerations are matching well with previous research results and the distribution of the building damage index has a similar pattern with isoseismic lines. Keyword: seismic intensity, isoseismic lines, ground acceleration, attenuation, damage index. 1 Introduction According to several sources (Walter et al. [24]; Tsuji et al. [23]), the focus of th the 27 May 2006 Yogyakarta earthquake with Mw = 6.2 was at approximately 10 km depth and only 15 km away from Yogyakarta city. Elnashai et al. [7] and Tsuji et al. [23] stated that there are several versions of the location of the epicenter.
