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: Kajian kawasan lindung untuk penataan ruang yang ramah lingkungan
Abstrak: Increase of human population leads to the higher demand of land to accomodate human activities for their livelihood. On the other hand, land availability is limited. Consequently, if the need and availability of land are not balance properly, it will trigger conflict and competition between activities it self and land use. This will bring to a situation where shifting land utilization is not compatible to the regilation on spatial planning and their capacity. Therefore, spatial regional planning is needed to achieve balance between cultivation and preservation areas. Objectives of this research were: 1) to identify the preservation areas in Bogor District based on this bio-physical condition; 2) to analyze the spatial utilization discrepancy of preservation areas; 3) to analyze the population presure on preservation areas. The analysis was approach bt using Geographic Information System and applying criteria mentoned on the Presidential Decree Number 32 Year 1990 concerning Management of Preservation Areas. Population presure indocation was decided by the value of Population Presure Index. Analysis result based on that decree showed those areas which should be decided as preservation areas in Bogor District were 113,110 ha or 37.83% of the entrie district. The analysis result found that 20.99% of preservation areas based on the decree had been allocated as preservation areas on Bogor District Spatial regional Planning Year 2000-2010. th erest (79.01%) was not allocated based on that decree. The disrepancies were resulted because on map of Bogor District Spatial Regional Planning Year 2000-2010 had not allocated water catchments area, ;ocal preservation area and dangerous area. It was found that 61.98% of the preservation areas of analysis result based on the decree was under population presure (Population Presure Index >1). Therefore, some areas that have high population presure required alternative efforts to change attitude pattern of inhabitant that are expensive and exploitative to preservation areas. Those are application of application of policy on incentive-disincentive system, society empowerment and collaborative management on preservation araes among government, privates and society around preservation areas

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%.
