Abstrak: The land potential for pond aquaculture in Batang has not mapped optimally. The objectives of this study are to map a potential area and designing eco-friendly pond aquaculture coastal of Batang, Central Java. Such spasial data processing method was used for this study. Spasial analysis used overlay techniques, criterias consists of some physical parameters included soil type, soil texture, slope of land, land usage, distance from shore, and distance from river. Quantitative assessment was done for degree of land suitability with scoring and weighting factors each parameter. Designing eco-friendly pond aquaculture was conducted for analysis spatial planning in Batang that consider several factors, are water supply, land contours, border of coastal and rivers, outlet and inlet which accordance to the actual condition. The area potential zones for pond aquaculture in Batang coastal are categori in three group very appropriate 8855.44 Ha, appropriate 4381.96 Ha, and not appropriate 18952.90 Ha. Based on the results were obtained, sub-district of Batang, Subah, Gringsing are the most suitable zone for pond aquaculture in Batang coastal.

Judul: The Direction of Aquaculture Development for supporting Regional Development (A Case Study on Cianjur Regency).
Abstrak: Cianjur Regency is one of the potential areas for developing aquaculture. The largest part of total fish production came from the floating net cages (“Keramba Jaring Apung”-KJA) Cirata Dam. Recently, the condition of Cirata Dam is facing to degradation of its environment quality. Thus, the other alternative aquaculture developments required are freshwater ponds and paddy field (minapadi system). The efforts of fishery development in freshwater ponds and minapadi should be done in the context of regional development. Therefore, the objectives of this study were: (1) to identify existing region for aquaculture and irrigated paddy field; (2) to analyze land suitability and availability for freshwater ponds and minapadi; (3) to analyze superior commodities of freshwater fish in each district; (4) to analyze the fisheries linkages with other sectors; (5) to formulate a direction of aquaculture development. This study was conducted in Cianjur regency using primary and secondary data. Primary data was from interviews, questionnaires, observation and water samples. Secondary data was obtained from institutions. The analysis used in this study were land suitability and availability for freshwater ponds and minapadi, the determination of main commodities of fisheries, Input Output (I-O) and A’WOT (AHP and SWOT combined analysis). Land suitability and availability for freshwater ponds were analyzed using Geographic Information System (GIS) and Multi-criteria Evaluation (MCE) methods. Multi-criteria is the approaches or methods that aid an evaluating according to several criteria which ultimately may lead to better decisions. It started with distribution of weight for criteria, factor and sub-factor using Analytical Hierarchy Process (AHP). Then, the weight will be analyzed using GIS. Land suitability and availability for minapadi was analyzed using matching methods. Land suitability for minapadi system in this research was built based on land suitability for paddy field and availability of irrigation area. The analysis result of land suitability and availability showed that the suitable land for freshwater ponds was 86.511 hectares (23,89 % of total region). Of such suitable land, the suitable and available land was 74.062 ha (20,46%) and suitable but not available land was 12.449 ha (3,44%). The potential land in S1 (very suitable) class can be found at northern Cianjur (14 districts), central Cianjur (3 districts) and southern Cianjur (2 districts). The development of freshwater ponds also can be directed in suitable (S2) class which were potential at the northern and southern Cianjur. The marginally suitable (S3) class were potential at the central and southern Cianjur. Analysis result of land suitability and availability for minapadi showed that suitable land was 13.004 hectares (3,59% of total region). Of such suitable land, the suitable and available land was 9.553 ha (2,64%), while suitable but not available land was 3.451 ha (0,95%). The suitable and available land mainly at ix northern Cianjur, that is Bojongpicung, Ciranjang, Cikalongkulon, Haurwangi, Karangtengah, Mande and Sukaluyu. This potency can be raised if the irrigation network was developed mainly in southern Cianjur region, because of the high land availability of paddy field. The potential lands for freshwater ponds and minapadi need to be used in order to increase fish production. One of ways is efficiency by

Judul: Prenilasi Senyawa β-Diketon sebagai Prekursor 3-Prenilflavon
Abstrak: One group of flavonoids that has not been commonly synthesized is 3- prenylflavone. The main objective of this experiment was to synthesize precursor of 3-prenylflavone. Firstly, β-diketone was synthesized via 4 steps from phenol as starting compound with total yield of 24%. Prenylation of β-diketone with prenyl bromide and K2CO3 base produced 4 fractions which were separated by using preparative thin layer chromatography (PTLC) with n-hexane:EtOAc (8:2) as the eluent. Fraction with Rf = 0.80 was further separated by using preparative PTLC with n-hexane:EtOAc (99:1) as the eluent. Two fractions were obtained with Rf = 0.38 and 0.42. The first fraction has been characterized as diprenylated β-diketone with 49% yield. Application of protecting group on the phenolic OH group in β- diketone are needed to obtain monoprenylated β-diketone which can be further cyclized into 3-prenylflavone
