Judul: Sinkage prediction model of a four-wheel tractor based on plate sinkage test
Abstrak: Sinkage of a tractor on a field will cause motion resistance which reduces its traction. This will lead to the reduction of tractor’s efficiency. This study was conducted to predict the sinkage of a four-wheel tractor based on plate sinkage test. The parameters used for the plate sinkage test were load, physical and mechanical properties of soil (water content, bulk density and penetration resistance) and the dimensional parameters of the plate (the plate area and contact shape ratio). The method used were predicting sinkage using plate sinkage test with special consideration on contact shape ratio and comparing the model with Bekker’s sinkage model (1960). The test resulted that water content and load on area of plate were significantly affect the depth of sinkage as a parameters. The model which is has the best correlation to the sinkage of tractor is k2 model i.e. 7 6 6 69

Abstrak: Load of a tractor on certain terrain condition may cause sinkage, which results motion resistance on its four wheels. This motion resistance reduces its mobility and decreasing work capacity. This research was aimed to predict the sinkage of a fourwheel tractor based on human footprint approximation. The parameters examined for the sinkage prediction were pressure and the physical properties of soil. Based on the observations, water content can be used as representative of other soil properties. Through linear regression analysis, some equation models for predicting human footprint and tractor sinkage were obtained. The equation models employed water content and normal pressure as the independent variables. Those models were then compared with the observed tractor’s sinkage to find the best fitted model. Equation model zkskid = 12.804 - 0.275(ka) + 6.56(P) through male subject and zkdkab = 18.028 - 0.262(ka) - 7.304(P) through female subject were the best fitted model that can be used for sinkage prediction of four-wheel tractors.

Judul: Sikap Masyarakat Terhadap Penayangan Program Hiburan Musik Dangdut Di Televisi. Kasus Rw 01 Desa Laladon, Kecamatan Ciomas, Jawa Barat
Abstrak: Pada saat ini setiap stasiun televisi di Indonesia saling bersaing dalam mengemas berbagai program acara. Fenomena ini dapat dilihat seperti pada persaingan stasiun televisi dalam menayangkan program hiburan musik dangdut, karena hampir setiap stasiun televisi swasta merniliki program hiburan musik dangdut. Fenomena persaingan ini didukung ketika munculnya sosok penyanyi dangdut seperti lnul Daratista pada program hiburan musik dangdut di salah satu stasiun televisi swasta. Hal ini seperti diungkapkan oleh Adiningsih (2003) bahwa kenunculan lnul yang menaikkan rating stasiun SCTV dalam program hiburan musik dangdut walaupun pada tayangan perdana, memicu Stasiun-stasiuti televisi swasta lain untuk berlornba-lomba hanya untuk bisa menarnpilkan lnul. Stasiun-stasiun televisi terrsebut terkesan mengekor, melihat kesuksesan salah satu program hiburan dangdut.
