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

Judul: Sinkage prediction of Terrestrial Robotic Vehicle (TRV) using plate sinkage test
Abstrak: Plate sinkage tests method have been performed by many researchers to assess the sinkage of conventional off-road vehicles, one of it is Bekker’s model. The need of sinkage prediction for Terrestrial Robotic Vehicles (TRV) is necessary, hence the objectives of this study was to determine sinkage prediction for TRV based on plate sinkage test method. The methodology used in this study was the measurement of sinkage of several plates with different area and contact shape ratio on a terrain with different physical and mechanical properties. The plate sinkage test’s results were compared with the observed sinkage of TRV in static and dynamic states. Microsoft Excel and SPSS 17 software were employed to process and analyze data. The results showed that linear regression models of plate sinkage tests with the highest coefficient of determination is the model plate sinkage tests Z’5. The test plate sinkage model is Z’5= -7.903 + 0.100 P + 0.303 KA for soil types CL (clay loam) with a moisture content content of 29.43%, up 32.29% and bulk density g/cm3 1.06 g/cm3 until 1.18 g/cm3.

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.
