Judul: Estimation of Sustainable Harvest Quotas and Costs of Timor Deer Breeding Using Intensive and Semi-Intensive Systems
Abstrak: Stunting merupakan bentuk malnutrisi pada balita diakibatkan kurangnya zat gizi seperti protein. Daging rusa dapat dijadikan alternatif pemenuhan protein hewani karena ketersediaan di alam maupun penangkaran. Penelitian ini bertujuan menduga nilai parameter demografi, menduga kuota panen lestari, dan menilai penangkaran yang lebih efektif dan efisien antara penangkaran intensif (HP Dramaga) dan semi-intensif (IPB Darmaga). Pendugaan parameter demografi dan analisis penangkaran yang efektif dan efisien dikedua penangkaran dilakukan dengan analisis logbook, observasi, studi literatur dan wawancara, sedangkan pendugaan kuota panen melalui analisis logbook dan studi literatur. Hasil menunjukkan penangkaran semi-intensif memiliki prospektif populasi yang lebih bagus dengan laju pertumbuhan populai sebesar 0.29. Berdasarkan kuota panen lestari dan analisis finansial, penangkaran yang lebih efektif dan efisien adalah penangkaran semi-intensif dengan total kuota panen sebanyak 16 ekor dan intensif 10 ekor. Analisis finansial menunjukkan nilai NPV, BCR, dan IRR penangkaran semi intensif lebih tinggi, dengan payback period 9.80 tahun.

Judul: Perencanaan Penangkaran Rusa Timor (Cervus timorensis de Blainville) dengan Sistem Farming : Studi Kasus di Penangkaran Rusa Kampus IPB Darmaga
Abstrak: Timor deer (Cervus timorensis de Blainville) is one of Indonesia wildlife species which population growth on natural habitat facing many threats as impact of human activities, like wild hunting and habitat destinction and fragmentation. Timor deer can be developed as livestock in the future its ability in difference geographic area of Indonesia. Farming system is appropriate model to be developed, because majority of Indonesian farmers ha ve about less than 1 hectares of farm area. The objectives of this research are: to analyse suitable location, to analyse breeding plan and economical aspect. The research was caried out in captive breeding field labratory of IPB Darmaga Campus. Equipments which have been used are: digital camera, rool meter, weighing-machine and a set of computer with design program. Materials which used are: map, timor deers and plastic bags. This research used field observation method, literature study and interview method. Pursuant to this research with based on bioecological condition, IPB captive breeding is suitable for timor deer captive location. Farm location was devideed into: headquarter zone 0,10 hectare (2,35%) and captive breeding zone 4,15 hectare (97,65%). Captive breeding management to be executed is farming system. Based on economic analysis, until 21,35% interest, captive breeding with farming system still give advantage if population size of parent stock in first year are 105, and 210 in second year and to be taken care until ninth year, with payback period 4,53 years.

Judul: Karakteristik Carboxymethyl Chitosan Dengan Variasi Konsentrasi NaOH
Abstrak: Carboxymethyl chitosan is chitosan derivative product obtained from chemical modification. CMCh were made by alkalization process and carboxymethylation process. Factors that affect CMCh characteristics were excess sodium hydroxide in alkalization process, ratio between chitosan and monochloroacetic acid, and carboxymethylation temperature. The objectives of this research were to study the NaOH effect to CMCh characteristics, to learn process of making CMCh, to set the proper concentration of NaOH, and to analyze CMCh characteristics. CMCh yields were 110.72%-114.22%. CMCh pH value were 3.74-4.31. The optimum NaOH concentration to obtain the best CHCh was 10 M. Percentage of CMCh moisture content was 10.70%-11.42%. Ash content and nitrogen content of CMCh were 0.49%-0.50% and 4.52%-4.81%. CMCh viscousity was 8.25 cps. Percentage of CMCh solubility was 61.61%-91.50%. The different functional groups from chitosan which observed in CMCh were C=O group, CH group from alkene functional group, C−O group, and C−O−C group.
