Judul: Evaluasi Kawasan Lindung dengan Aplikasi Sistem Informasi Geografis (SIG) di Kabupaten Pandeglang, Banten
Abstrak: The space necessity is increasing along with the growth of population. It is become one of things which causing exploitation of natural resources and abuse of space using. Protection area is a supporting system for life, it is useful for caring the environment balance, but in fact it has destroyed and changes its function. Pandeglang is one of potential area and has problem with environment. Geographic information system (GIS) can perform the newest data and help to get decision of space policy to push the protection area management which attend its protection function to realize friendly environment development. The research carried out on September until November 2009 in Pandeglang Regency, Banten. The research purpose is to identification legal formal protection area based on President decision Number 32 on 1990 about protection area management and ministry agriculture decision Number 837 on 1980 about criteria and method arrangement protected area decision, identify the protection area gap and abuse and strategy formulate and direction policy of management legal formal protection area. The data was got in thematic map, remote sensing and direct observation. Data tabulation included spatial and attribute data tabulation with ArcView, ArcGIS and Erdas Imagine software. Data analysis was based on the results of overlay analyst and the percentage of deviation (summary) analyst between digital maps. Evaluation toward space pattern and space protection area structure. Actual protection area DFH based on Distribution of forest function (DFH) in Pandeglang Regency is Ujung Kulon National Park (TNUK), Nature Recreation Park (TWA) Carita and forest protect totally 66.465,15 Ha (23,64%). Actual protection area RTRW based on space area allocation in space area arrangement plan (RTRW) in Pandeglang Regency is TNUK and forest protected in the amount of 68.782,06 Ha (24,46%) and legal formal protection area is 173.160,13 Ha (61,58%). Gap between legal formal protection area with Actual protection area is 99.957,20 Ha (35,55%).Protection area condition all dominated by forest with different wide. Actual forest protection area DFH wide is 43.800,65 Ha (65,90%), actual protection area RTRW is 41.965,34 Ha (61,01%), legal formal protection area is 50.328,99 Ha (29,06%). Space arrangement is needed to realize movement development, but there is an abuse and inconsistency in planning step. Legal formal protection area abuse in actual protection area is 110.458,85 Ha (63,79%); legal formal protection area abuse in RTRW is 110.874,43 Ha (64,03%); actual protection area abuse DFH in actual RTRW is 8.082,16 Ha (12,16%); unsafe area from natural disaster abuse in actual protection area RTRW is 66.594,42 Ha (74,24%). Direction and strategy in protection area management in Pandeglang Regency needs some steps. In pressing legal formal protection area management by pointing the instance or institution with giving them authority and responsible to manage legal formal protection area especially in unsafe area from natural disaster and local protection area. RTRW document review is needed contrive to vi actual data from the instance and use similar format of data reference and consisten in space arrangement.

Judul: Evaluasi Kawasan Lindung Berdasarkan Rencana Tata Ruang Kabupaten Cianjur, Provinsi Jawa Barat (Aplikasi Sistem Informasi Geografis)
Abstrak: Cianjur Regency is a potential area for economic growth. The higher rate of population growth resulted in land use and conversion into residential areas. It encouraged the local officer to carry out an appropriate and environmental friendly regional and spatial planning. Evaluation of protected areas which based on spatial planning was emphasized on the suitability of protected area allocation in the field. Monitoring of protected areas and spatial planning areas required continuous data. The use of Geographic Information System (GIS) and remote sensing were one of the ways to get the data. The study was aimed to evaluate protected area based on spatial planning Cianjur Regency period 2005-2015 Landsat Image-5 TM 2007, digital map of spatial planning of Cianjur Regency period 2005-2015, base map, and population data were used in this study. Data tabulation included spatial and attribute data tabulation. The activity that conducted in the field was interview, observation, and ground truth. Data analysis was based on the results of overlay between land cover maps and digital maps of spatial planning. Deviations occurred were analyzed by using the percentage of deviation. The evaluation of protected areas showed that there compared to deviation into actual land cover of 41,578.92 hectare or 32.89%. This deviation happened from protected areas into plantation land cover classes, garden mix, agricultural land, bush, land up, and open land. The deviation of utilization in cultivate area of 65,618.73 hectare or 30.33%. Recommendations of the deviations occurred according to existing conditions in the field and policy-related spatial planning of Cianjur Regency. As recommendation, an institution that responsible in controlling and maintaining protected areas was needed to make sure good implementation of spatial planning. It was also needed to do land rehabilitation in protected land where degradation happened and relocation of people.

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%.
