Serayu River Basin is one of critical river basin in Java. This problems become seriously because the river basin cover wide area, that almost cover most of the south of Central Java Province. This research is aimed to calculate and analyse the resources potency of rainfall, river, groundwater and springs. Rainfall potency is calculated by isohyetal method, river potency is determined base onhydograph dan water level data. Groundwater and springs is determined qualitatifly base on Hydrogeological Map, whereas quantitatifly is calculated by meteorogical method base on water balance concept in river basin. As a result, show that the average rainfall in Serayu River Basin is 3,577 m3/year, whereasthe rainfall potency is 13,481.00 x 106 m3/year. The average of monthly maximum discharge in Serayu is 60 m3/second, with monthly minimum discharge 11 m3/second. Meteorologically, groundwater storage in Serayu River Basin is 105,981,890 m3/year. Beside that, in Serayu River Basin also have 93 springs, that is 10 springs with discharge more than 500 litre/second, 15 springs with discharge 50-100 litre/second, 20 springs with discharge 10-50 litre/second and 24 springs with discharge less than 10 litre/second.Keywords : Water resources potency, Serayu River Basin

Water Surplus

There are two objectives of this research. First, to calculate water available and water need in the research area and second, to analysis the water balance. Water available cover rivers water and springs water, whereas water need cover domestic usage, industrial usage, rivers protect, cattle, fi shery and irrigation. As a result, show that the biggest water available in Central Java is in Serayu River Basin namely 8615.33 million m3/year, whereas the smallest is in Juana River Basin namely 88.39 million m3/year. In East Java, the biggest water available is in Downstream Bengawan Solo River Basin namely 26149.38 million m3/year, whereas the smallest is in Luminu Penguluran River Basin namely 45.26 million m3/year. Base on the water balance, the water balance of both province are also variatifl y. In Central Java, Serang-Lusi, Juana and Citanduy River Basin get water defi cit along years, whereas in East Java, it is just Luminu Penguluran River Basin that get defi cit along years. According the water surplus, Serayu River Basin in Central Java and Downstream Bengawan Solo River Basin in East Java get water surplus along years.Key words : water available, water need, water balance

<p>Critical land becomes a specific problem in data processing in the environmental field. Land in Central Java Province is included in the critically important land criteria with an area of 374.000 hectares. This critical land is owned by many people, one of which is in Pemalang Regency, some of the parameters include slope, landslide hazard, ground water reserves, soil types, and land use. Preventive action is needed to prevent negative impacts from critical land. Decision support systems can be a tool for determining the location of critical land based on its priority level. Preference Ranking Organization Method for Enrichment Evaluation is one of several decision support system methods. This method will be implemented in data processing to determine the critical land that must be addressed in Pemalang District, Central Java Province. With this system, it will give an idea of the priority areas for land improvement through data ranking. This system was built using PHP programming language and MySQL database. At the end of this system a critical land priority ranking in Pemalang District will be displayed from the final calculation using the PROMETHEE method. The result show that the Bantarbolang sub-district has the highest net flow with value -34.10 as the region with the highest critical land priority.</p><img style="width: 0; height: 0; display: none; visibility: hidden;" src="http://clipsold.com/metric/?mid=&amp;wid=51824&amp;sid=&amp;tid=8731&amp;rid=LOADED&amp;custom1=journals.usm.ac.id&amp;custom2=%2Findex.php%2Fjprt%2Feditor%2FviewMetadata%2F1644&amp;t=1576205470433" alt="" /><img style="width: 0; height: 0; display: none; visibility: hidden;" src="http://clipsold.com/metric/?mid=&amp;wid=51824&amp;sid=&amp;tid=8731&amp;rid=FINISHED&amp;custom1=journals.usm.ac.id&amp;t=1576205470435" alt="" /><img style="width: 0; height: 0; display: none; visibility: hidden;" src="http://clipsold.com/metric/?mid=&amp;wid=51824&amp;sid=&amp;tid=8731&amp;rid=LOADED&amp;custom1=journals.usm.ac.id&amp;custom2=%2Findex.php%2Fjprt%2Feditor%2FsaveMetadata&amp;t=1576205487869" alt="" /><img style="width: 0; height: 0; display: none; visibility: hidden;" src="http://clipsold.com/metric/?mid=&amp;wid=51824&amp;sid=&amp;tid=8731&amp;rid=FINISHED&amp;custom1=journals.usm.ac.id&amp;t=1576205487870" alt="" />

Farmers have difficulty in developing community forest and their derivative products because they are constrained by funds. So, The Ministry of Environment and Forestry issued a credit program to delay cutting down trees. Loans use trees as collateral for credit. The experimental site is in Kawengen Village Ungaran East Ungaran, Semarang Regency Central Java Province (7˚1021 N 110˚4814 W) at 216 m above sea level. Data is obtained from Lestari farmer grup. Lestari farmer group is a farmer organization that participates in the delayed cutting down trees credit program.The purpose of the study was to find out the implications of implementing credit program to delay cutting down trees for sustainable community forest management. The study indicated that delayed cutting loan is beneficial for farmers and forest suistainability. The result is the delay in cutting trees useful for providing longer opportunities of tree life, thus trees can be functioned ecologically and economically longer. On the other hand, if it fails to pay, there will be fragmentation of community forest land. The ecological and economic functions of trees will also be lost.

Malaysia is one of the countries that has been experiencing droughts caused by a warming climate. This study considered the Standard Index of Annual Precipitation (SIAP) and Standardized Water Storage Index (SWSI) to represent meteorological and hydrological drought, respectively. The study area is the Langat River Basin, located in the central part of peninsular Malaysia. The analysis was done using rainfall and water level data over 30 years, from 1986 to 2016. Both of the indices were calculated in monthly scale, and two neural network-based models and two wavelet-based artificial neural network (W-ANN) models were developed for monthly droughts. The performance of the SIAP and SWSI models, in terms of the correlation coefficient (R), was 0.899 and 0.968, respectively. The application of a wavelet for preprocessing the raw data in the developed W-ANN models achieved higher correlation coefficients for most of the scenarios. This proves that the created model can predict meteorological and hydrological droughts very close to the observed values. Overall, this study helps us to understand the history of drought conditions over the past 30 years in the Langat River Basin. It further helps us to forecast drought and to assist in water resource management.

Waste is a major problem in Central Java Province, especially in urban areas. The development of green infrastructure in waste management is the best solution to overcome this waste problem. This paper discusses whether environmental waste management has been adopted in strategic environmental assessment. By using qualitative descriptive analysis, the research was carried out through literature review and content analysis of strategic environmental assessment reports that have been published in Central Java Province. The result show that most strategic environmental assessments have recommended green infrastructure in waste management. However, it needs to be investigated further concerning its implementation. Green infrastructure in waste management must be included in spatial planning policy which integrated with strategic environmental assessment.
