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: Penggunaan/Penutupan Lahan dan Kaitannya dengan Pertumbuhan Ekonomi Wilayah (Studi Kasus Kota Bogor)
Abstrak: Rapid population growth will implied the need for space to accommodate their activity. And one of it manifested in the shape of built up area. On this land then this population do their activity, individually or in a group. The aims of this study were namely, to analyzes changes in land use/land cover of Bogor Municipality between 2005 and 2007, to analyzes the influence of economic factor to the land use/land cover compositions, and to analyzes the consistency between land use of the Bogor Municipality in 2007 and Regional Spatial Plan (RTRW). In 2005, Bogor Municipality land use/land cover was dominated by settlement with 31,1% (3.563,01 Ha), followed by paddy with 23,2 % (2.656,07 Ha) and urban forest with 13,9% (1.592,75 Ha). There were no change in the land use/land cover domination in 2007. Settlement still dominating Bogor Municipality land use/land cover with a little increase, which is 31,3% (3583,98 Ha). Paddy with the same percentage, which is 23,2% (2658,88 Ha) on second place and urban forest with 13.9% (1592,79 Ha) in third place. Between 2005 and 2007, there were 109,14 Ha land use/land cover change that occurs in Bogor Municipality. The transformation from non used space became a residential is the most dominating transformation, which reach 45 Ha. Followed by the transformation from field became a residential with 21,75 Ha and the transformation from non used space became fields is on the third place with 12,67 Ha. The growth of the population equal to the demand for housing. This is the reason for the developer to build new residential. The Bogor outer ring road project is also suspected as the trigger to the growth of residential area. With this infrastructure built, these new residential will have the best accessibility to or from Jakarta, which is the centre of economic activity in Indonesia. Bogor Municipality consist of two hierarchy, first hierarchy and third hierarchy. The third hierarchy consist of 57 villages. While another eleven 11 were classified as the first hierarchy. Essentially, the first hierarchy is the centre v of general activity and economic activity, which is why the first hierarchy is dominated by built up area, while the third hierarchy is commonly dominated by the non built area. There are two kinds of the inappropriateness between Regional Spatial Plan and 2007 land use. The first one is the Regional Spatial Plan which was built less than the allocated plan, which is dominated by the allocation for health facilities, with 1,8 Ha over 18,3Ha which was allocated. The second is the Regional Spatial Plan which was built more the allocated plan, which is dominated by the allocation for agriculture with 128,4 Ha allocated, but built up to 408,1 Ha. By identifying the inconsistencies of actual land use to Regional Spatial Plan (RTRW), spatial plan deviations in Bogor Municipality can be identified.

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.
