Judul: Karakteristik Hubungan Infrastruktur Pertanian dan Pola Ruang Terhadap Neraca Pangan (Studi Kasus Lahan Pertanian Pangan Berkelanjutan Kecamatan Tarogong Kidul, Kabupaten Garut)
Abstrak: The availability of agricultural land in Tarogong Kidul District is threatened because Tarogong Kidul belongs to urban area of Garut. The purposes of this research are to determine, (a) the spatial distribution of land use and paddy fields, (b) the influence of agricultural infrastructure on the agricultural land development, and (c) the level of food security and status in Tarogong Kidul. The techniques to determine spatial distribution of land use in 2007 and 2014 are by digitizing process and interpretation based on IKONOS imagery in 2007 and 2012. The influence of agricultural infrastructure were measured by paddy fields area in 2007 and 2014 based on road border 50 – 800 metres, identification of irrigation network and its effect on the productivity. Hierarchy analysis process and overlay results from the previous maps were used to determine rice fields which are vulnerable to conversion and the level of local food security. Land use of Tarogong Kidul is dominated by paddy fields and settlements. Paddy fields spread out at the south and west while settlements spread out at north and east that is adjacent with urban of Garut. The results showed that road border, road status, irrigation and productivity has consecutive weights of 0.48, 0.47, 0.04, and 0.01. Based on the map, the highly vulnerable status of conversions are located near urban Garut and spread out through out the district. Based on food balance sheets, there are six villages deficit status and 6 villages surplus status. Theory this analysis of the food security status of South Tarogong will be surplus until 2016.

Judul: Analisis Spasial Konversi Lahan Sawah Menuju Ketahanan Beras Domestik di Kecamatan Ciampea Kabupaten Bogor
Abstrak: Bogor regency has high of population growth, economy, and infrastructure so that the need for residential land is also high. Land conversion to settlements is irreversible (not-return) and has long-term impact. Conversion of paddy fields to settlements has impact to food security. The aim of this research is to: analyze the distibution of paddy fields based on slope and road distance, analyze socioeconomic of paddy fields farmer and determine the adequacy of domestic rice and the potential threat of domestic rice security due to. The techniques used are the analysis of images to find out characteristics of land cover/use and see the distribution of paddy fields by slope and distance of the road, determine the socioeconomic characteristics of paddy field farmers through interviews, logistic regression to determine factors affecting land conversion, calculation of the balance of the rice, and overlay to find out rice security threat. The type of land use in sub-district Ciampea dominated by dryland, mixed farming, and rice fields. The existence of paddy fields and farming are dominant at southern regions and a small portion is at the northern area. The result of regression analysis logistics binary obtained that the variable of broad rice fields ( X5 ) has the most influential factor.The equation is (Y) =-49.769 + 8.193X5. Based on the level of rice security threat, 9 villages belong to categorized of medium and 4 villages belong to high category, while based on level of potential rice fields conversion 8 villages belong to categorize of low, 2 villages belong to medium category and 3 villages belong to high category. The balance of rice in the sub-district Ciampea is deficit, because almost entire village belong to deficit status and only one village has surplus status. This condition has threaten the availability of rice while the level of potential rice fields conversion dominanted by low category and has failed to fullfil domestic food security in sub-district Ciampea, as it’s dominant villages belong to medium category.

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%.
