Abstrak: Thin-tailed sheep is one of local sheep that can help to support the needs of society’s animal protein. Wafer complete feed of waste vegetable market is one of the feed results of technology that has nutritional value better than feeding a conventional feed (forage and rice bran). A number of 15 thin-tailed sheep was given wafer complete feed of waste vegetable market at different levels. The purpose of this study was to compare the effect of wafer complete of vegetable waste treatment on different levels to the productivity of thin-tailed sheep. Parametes measured were feed consumption, daily weight gain, feed conversion, and income over feed cost (IOFC). The results obtained were treatment with wafer complete of vegetable waste were able to increase the sheep’s body weight, but didn’t effect on sheep’s daily consumption. Wafer complete feed of waste vegetable market that was given 100% to the sheep had the lowest feed conversion. Meanwhile, level of 25% wafer complete feed had the highest value of IOFC

Abstrak: Inner part of cassava peel is one of agriculture by product that can use as alternative feed in farm. Cassava peel has anti nutrition that called HCN, which limited factor to utilization. Feed is one of factor that influence meat quality, therefore it contents should be understand that is nutrition or anti nutrition. Physical properties of meat are important factor which determined in meat quality. This research was conducted to observed physical properties of thin tailed ram sheep’s meat which gave forage (Brachiaria humidicola) and cassava peel by differ level. This research used twelve thin tailed rams sheep under one year old with average body weight 19.06 ± 1.46 kg. The dietary treatments divided in four differ level of forage and cassava peel, included: 100% Brachiaria humidicola, 80% Brachiaria humidicola with 20% cassava peel, 60% Brachiaria humidicola with 40% cassava peel and 40% Brachiaria humidicola with 60% cassava peel. The variable observed tenderness, cooking loss, water holding capacity and pH value. The experiment design was randomize complete block design and the data analyzed by analysis of variance (ANOVA). The results showed that the experiment treatments have not significant effects (P>0.05). It concluded that cassava peel is able to be utilized as combination with Brachiaria humidicola up to 60% in level of ransom for sheep and it not influence meat quality by physical properties.

Abstrak: Various spatial objects in Bogor City have caused a significant increase of spatial data in Bogor City. These spatial data needs to be processed and analyzed using spatial data mining technique, which is able to extract the knowledge or patterns in the spatial database. This research extracts the patterns of terminals, stations, railroads, rivers, roads, and landuse characteristics using one of the spatial data mining techniques, namely spatial classification. In this research, the spatial relations between an object and its surrounding is determined using topological relations, with spatial operations such as contains, overlaps, equals, disjoint, intersects, within, crosses, and touches. The result of spatial classification accuracy using C4.5 algorithm is 72.117%. From this spatial classification result, the characteristics of spatial objects in Bogor City can be identified based on spatial operations.
