Judul: Karakteristik lemak dan kolesterol daging Domba Muda yang diberi ransum komplit mengandung minyak biji bunga matahari
Abstrak: Levels of fat and cholesterol in lamb meat could be intervened by modified feed using sunflower seed oil (Helianthus annuus) addition that were rich in linoleic fatty acids. The study was purposed to evaluate the effect of sunflower seed oil (MBBM) on the characteristics of lamb fat and cholesterol. The variables observed was the water content, fat content, the ratio of saturated and unsaturated fatty acids composition, cholesterol and numbers of thiobarbituric acid reactive substances (TBARS) in lamb meat. Total of 9 local lambs were divided into 3 groups and were given a treatment ration: P0 (complete ration without MBBM), P1 (complete ration with MBBM 4%) and P2 (complete ration with MBBM 6%). The treatment showed that the addition of the MBBM into the complete rations didn’t affect the variables observed. Generally this study showed that the addition of MBBM into complete ration up to 6% gave positive effect on ratio of saturated and unsaturated fatty acids composition, and it could decrease the level of lamb meat rancidity

Judul: Kualitas fisikokimia daging dan komposisi karkas domba muda yang diberi ransum komplit mengandung minyak biji bunga matahari
Abstrak: Penambahan minyak biji bunga matahari (Helianthus annuus) yang memiliki kadar lemak tinggi dapat meningkatkan kualitas sifat fisik daging domba muda. Penelitian ini bertujuan mengkaji penambahan minyak biji bunga matahari (MBBM) kedalam pakan terhadap sifat fisikokimia daging dan komposisi karkas. Peubah yang diukur adalah nilai pH, daya mengikat air, tingkat keempukan daging, susut masak daging, warna dan komposisi karkas. Sebanyak 9 ekor domba lokal jantan muda dibagi kedalam 3 kelompok dan diberi ransum perlakuan: PO (ransum komplit tanpa MBBM), P1 (ransum komplit dengan MBBM 4%) dan P2 (ransum komplit dengan MBBM 6%). Hasil penelitian menunjukkan bahwa penambahan MBBM kedalam ransum tidak berpengaruh nyata terhadap sifat fisik daging dan komposisi karkas, namun berpengaruh nyata terhadap warna merah daging. Dapat disimpulkan bahwa penambahan MBBM hingga taraf 6% tidak mengubah sifat fisikokimia daging dan komposisi karkas, namun membuat warna kemerahan pada daging sedikit memudar…

Judul: Sistem Informasi Geografis untuk Pola Aktivitas Manusia dengan Pemodelan Data Spatio-Temporal
Abstrak: The human activity in a given time period will shape its pattern. This research develops a spatiotemporal data model to support the prediction of human existence based on activity-pattern and also visualizes the activity locations in a GIS environment. This so-called mobility oriented spatiotemporal data model conceptualizes the spatial and temporal interaction of activity behaviour using the concept of mobility. In other words, activity patterns are conceptualized as a sequence of staying at or traveling between activity locations. The model can support the analysis and queries of activities from different perspectives, i.e. queries can be time-oriented, person-oriented, activity-oriented, and location-oriented. A prototype system based on the activity data modelling is implemented in MySQL 5.0.27 as DBMS with using PhpMyAdmin 2.9.1.1 software. Spatial database is developed with using software QuantumGIS and ArcView. The system could be accessed online through a web browser with MySQL as its database storage and Pmapper framework as the tools used in visualizing the activity locations.The information were provided in the form of activity attribute-data as the user requested and graphical-data (map) which contains information about its activity locations.
