Judul: THE EVALUATION OF THE URBANIZATION EFFECTS AS TRIGGER OF URBAN SPRAWL IN BOGOR, WEST JAVA
Abstrak: Urbanization is the main issue that altered the environmental condition nowadays. Urbanization means that there are changes in suburban areas to fulfill the function needed in the urban area. Nowadays, urbanization occurred due to the high demand of housing area with lower budget and comfortable environment of living condition. This condition was presented in the Bogor city case. Bogor is one of the oldest cities in Indonesia which is located in the southern part of Jakarta. Due to the increase of population in the capital city and increased of the higher price of housing, people started to looked for place to stay outside the city. Bogor located in the strategic location just close enough for people to commute to Jakarta. The transit city transform into commuting city. People works in Jakarta wanted to live in a more comfortable place of living and cheaper in price than the capital city started to see Bogor as an opportunity. Based on the data obtained by the Central Bureau of Statistics Jakarta in 2015, there are 187.777 total people commuted daily from Bogor to Jakarta. This condition also triggered by the better quality of access in and out Bogor. Mass rapid transportation and highway toll gate create more land cover changes potential to fulfill the high demand of housing. Thus, this research aimed to see the effect of highway toll gate in the land use cover change in Bogor city. Landsat Images was used using the timeseries method started since 1978 (the official year of Jagorawi Toll gate operation) with the 10 years interval time, 1989, 1999, 2009 and 2016. In determining the land use cover change, NDVI method was used which has been widely applied in detecting the greeneries. The result then evaluated using the supervised classification and validated using the Kappa Accuracy test. The result in 2009, showed that there was 56.97 km2 increase in the build area coverage. This was the highest total of increase rate in the build area coverage that detected through supervised classification. In 2009, Bogor has started to increase the quality of access in the northern part of Bogor. More development has been planned to be executed in the Northern Bogor such as Kedung Badak Toll gates, which will resulted in better access into the northern part of Bogor.

Judul: Analisis Perubahan Penggunaan Lahan, Pola Ruang dan Tingkat Perkembangan Wilayah di Kota Bogor
Abstrak: Bogor City is located 60 kms from the Indonesian Capital Jakarta and 120 kms from Bandung the capital of West Java Province. Strategic agricultural land and inexpensive land price have encouraged stakeholders to invest in agricultural sector and also non agricultural sector. Land use conversion is inevitable, although the goverment has set up the regulation to control land usage (Act No 26 year 2007). This research are conducted: (1) To analyze existing land use of Bogor City (land use in 2014). (2) To analyze the land use change in period of 2005-2012. (3) To analyze the consistency of existing land use compare to land allocation in the RTRW of Bogor City. (4) To identify regional development hierarchy level in Bogor City. (5) To determine factors that influencing land use change. This research was started with land usage map designing which retrieved from digitized result on administrative map 1: 5000 scales to ikonos image of Bogor City in years of 2005 and 2012. Consistency and inconsistency is obtained by overlaying land use map in 2012 and land allocation map of Bogor City years 2011-2031 (RTRW map). PODES is used to determine the regional hierarchy level by multiple regression method. Existing land use classified into 9 land use, in sequence from the largest one are: mixed garden, non-wellarrang ed settlement, paddy field, well arranged settlement, trade area, water body, dryland farm, open field and goverment office area. Dryland farm land use changes into 2 land use, open field land use change into 6 land use and paddy field land use change into 6 land use. The consistent existing land use compare to RTRW is 40.95% while inconsistence existing land use is 59.05%. During period of 2006 to 2012, most of regional development hierarchy in Bogor City are the relative constant hierarchy (42 villages/61.8%). 12 villages (17.6%) are increase in the hierarchy whilst 14 villages (20.6%) are decrease in the hierarchy. Factors that influencing land use change of Bogor City in period of 2005-2012 are: area of agricultural land in the years of 2005, social facilities growth, and economy facilities growth

Judul: Pelumas Aktif Dengan Bahan Dasar Minyak Ikan Dan Aditif Znochitosan Particle.
Abstrak: Pelumas memiliki peranan penting dalam meminimalkan fungsi keausan pada sistem mekanik. Synthetic liquids, minyak nabati (biolubricant) serta berbagai aditif telah banyak digunakan. Karakteristik minyak ikan dan sifat fungsional chitosan yang dapat berperan sebagai aditif, merupakan peluang dalam pengembangan pelumas baru yang ramah lingkungan. Tujuan penelitian adalah melakukan pembuatan dan karakterisasi pelumas aktif dengan bahan dasar minyak ikan dan aditif partikel ZnO-chitosan. Minyak dasar pelumas dibuat melalui reaksi epoksidasi minyak ikan dengan karakteristik bilangan oksiran (4,74±0,09) %, bilangan iod (49,91±1,9) gI2/100g, bilangan peroksida (59,33±3,05) meq/kg, dan asam lemak bebas (11,07± 0,10) %. Kombinasi aditif ZnO 0,5% dengan partikel chitosan 0,5% memberikan pengaruh terhadap pelumas minyak ikan dengan karakteristik terbaik, berupa scar diameter (1,16±0,04) mm, viskositas kinematik pada suhu 40°C (66,50±0,35) mm2/s dan korosi bilah tembaga grade 1A.
