Judul: The Role of The Spread of Nuclear Technology Rice to The Regional Development in Java a Case Study in Malang Districts and Bogor
Abstrak: Development in Java Island can be done through the development of paddy with favorable specifications. Java as a base of rice producers have the capability and suitability of land that allows for the development of the agricultural sector. The results of the study of nuclear science and technology in agriculture is expected to contribute to increasing the productivity of the national rice. Rice varieties nuclear technology research results have been deployed in 18 districts in Java. But there has never been research on spatial distribution maps as well as the response of farmers to rice nuclear technology. To determine the role of rice spread of nuclear technology to developing areas in Java, set the following research objectives: (1) determine the distribution map of the area in the island of Java which has been planting rice nuclear technology research results. (2) determine the role of stakeholders in the dissemination of rice varieties nuclear technology research results. (3) determine the level of adoption of rice farmers to the research of nuclear technology. (4) determine the role of rice nuclear technology to the development of the region. (5) provides policy direction rice seed dispersal of nuclear technology. The analysis was performed by using GIS analysis, stakeholder analysis, response analysis, schallogram analysis, and SWOT analysis. Distribution of rice nuclear technology results in Java has covered 18 districts with a total area of planting began in 2007 was 6,800 ha. The district is Bandung, Bogor, Karawang, Lebak, Pandeglang, Serang, Banjarnegara, Brebes, Sleman, Bantul, Demak, Jepara, Kudus, Pati, Purbalingga, Rembang, Jember, and Malang. Rice grown nuclear technology results include varieties Yuwono, Mayang, Diah suci, Mira-1, Bestari, and Inpari Sidenuk. The area is most widely spread of Malang is 1060 ha, while the area is the smallest spread of Bogor district is 100 hectares. Stakeholder mapping results showed Faculty of Agricultural Technology, Brawijaya University, Malang has a great interest and a small influence, involvement only in terms of the implementation of the program in terms of deployment and authority to implement rules and policies. BATAN and Distanhut Bogor Regency has a great importance and influence, however, influence and interests BATAN higher than Distanhut. BATAN involvement from planning, organizing, implementing, monitoring / evaluation. Distanhut involvement in the spread of rice is in terms of organization and execution. Farmers in Malang and Bogor and seed providers / breeder has little importance and influence. Farmers and seed providers depend on the seed stocks of BATAN, these stakeholders do the breeding and spread of seed if available, if not available, the presence of seeds they will plant other varieties. The results of the analysis showed farmers repons spreaders in Malang district judge deployment Yuwono varieties, Diah Suci, Mira-1, Bestari, and Inpari Sidenuk better than local varieties. It can be seen from the farmer to plant sustainability of nuclear technology despite the implementation of co-operation has ended. Farmers in Malang district judge spreader rice nuclear technology over the relative benefits, more appropriate, and can easily see the results compared to local varieties. Similarly, farmers spreader Bogor assess varieties Mira-1 and Pandanputri better than local

Judul: Studi Difusi Inovasi System of Rice Intensification (SRI) di Kabupaten Tasikmalaya (Kasus di Dusun Muhara Desa Banjarsari Kecamatan Sukaresik Provinsi Jawa Barat)
Abstrak: So far, research on most of the SRI innovation emphasizes the technology aspect. Meanwhile, research regarding the introduction of agricultural innovations to the farmers in Indonesia more emphasis on adoption of innovation at the level of individual farmers. This study aimed to determine (1) SRI innovation distribution maps in Tasikmalaya District in the Muhara Hamlet especially, since introducted until the research conducted, (2) SRI innovation diffusion process, particularly innovativeness, the pattern of adopter categories that occurred in the community and the rate of paddy SRI innovation adoption and the factors that influence it, and (3) whether there is any problem in implementing innovative programs SRI in Tasikmalaya District, particularly in the hamlet of cases and the factors influencing it. This study found that the majority of those classified as low in productivity, income level, the rate of introduction of SRI innovation from the mass media, the level of participation of farmers following the extension, nonformal education level and household level stratum of farmers, while classified as medium in terms of level complexity, triability level, observability level, the level of adherence to conventional cultivation farmers, farmers 'level of integration, the level of diversity of SRI innovation counseling methods, the level of formal education, communication and behavior patterns as well as high in SRI type of innovation decision making, the level of farmer’s needs for innovation SRI and adoption rate of SRI innovation. SRI has been running from 2006, in Hamlet Muhara but still found some problems that arise. The problem is not locally available organic fertilizers, pest control is still low and the perceived marketing SRI paddy farmers still do not provide benefits for not providing the expected added value. Therefor, need assistance in the form of supplying the holding of a couple holding livestock in the form of goats, chickens, guinea pigs, ducks and other in a revolving system from one farmer to another farmer, induction of pest control experts to provide training how to cope with pests by using the method of Participatory Rural Appraisal (PRA) and the importance of awareness about organic agriculture, there is a willingness from the Department of Agriculture Tasikmalaya to make efforts so that SRI rice marketing can provide significant benefits for farmers by establishing agreements with distributors who can market the SRI paddy farms in Muhara with competitive prices and also provide training to farmers on organic agriculture certification standards set

Judul: Katalis Zink Ferit Tersubstitusi Cu untuk Oksidasi Benzil Alkohol
Abstrak: Katalis berperan dalam menurunkan energi aktivasi. Katalis ZnFe2O4 dan ZnFe2O4 tersubstitusi Cu disintesis menggunakan metode kopresipitasi untuk digunakan dalam oksidasi benzil alkohol. Katalis dicirikan dengan spektrofotometer inframerah (FTIR) dan difraktometer sinar-X. Spektrum FTIR menunjukkan puncak serapan dari ikatan Zn-O dan Fe-O masing-masing pada rentang 559‒575 cm-1 dan 419‒447 cm-1. Difraktogram menunjukkan terbentuknya fase tunggal Zn0.6Cu0.4Fe2O4 pada katalis ZnFe2O4 tersubstitusi Cu 20%. Benzil alkohol dioksidasi dengan sistem refluks. Konversi benzil alkohol meningkat dengan meningkatnya suhu. Kadar benzaldehida yang dihasilkan dengan katalis ZnFe2O4 tersubstitusi Cu 20% lebih tinggi dibandingkan dengan katalis ZnFe2O4 yang tidak tersubstitusi dan yang tersubstitusi Cu 60 dan 80%. Hal tersebut menunjukkan bahwa katalis ZnFe2O4 tersubstitusi Cu 20% memiliki kinerja yang lebih baik dalam oksidasi benzil alkohol menjadi benzaldehida dengan kadar benzaldehida 8.763%.
