Judul: Perubahan Penggunaan/Penutupan Lahan dan Keterkaitannya dengan Luas Ruang Terbuka Hijau ( Studi Kasus Kota Bogor )
Abstrak: The presence of a city has a goal to meet the needs of the population in order to survive and continue living and improve quality of life. However, with the development of a city, there are some fairly complicated urban problems to overcome. Rapid increase in population accompanied by an increase in income per capita has resulted in the need for land to meet the needs of food, clothing, and shelter. Urban developments lead to negative consequences for the environment. Urban environment tends to develop economically and decline ecologically where the city tends to lead to physical development such as infrastructure development. This research was conducted to analyze the change of land use/land cover of Bogor City period 2000-2011, analyzed the level consistent/inconsistent RTH development based on RTRW Bogor City allotment, and analyzed the level of development of Bogor City based on the RTH condition. Land use/land cover in Bogor City in 2000 and 2011 divided into land use/land cover of land classified as RTH and Non-RTH. Land use/land cover which is classified as RTH such as paddy, upland fields, botanical garden, sport fields, public cemeteries, trees, and bushes. While land use/land cover which is classified as non RTH such as bare soil, pools, situ, rivers, settlement, build non settlement (industry, state palace, health area, educations area, station and terminal, commerce area, offices roads, railway stations, and road). Distribution of land use/land cover in the City of Bogor both in 2000 and 2011, dominated by settlements, paddy, and trees. The size of settlements hectares increased from 4.469,9 Ha to 5.289,8 Ha, the large of paddy decreased from 2.904 Ha to 2.452 Ha, and the area of trees decreased from 2.341,2 Ha to 2.108,1 Ha. Settlements experiencing the largest increase due to 360,3 Ha consequence paddy conversion. Appropriateness criteria based RTRW divided into consistent, undeveloped consistent, and inconsistent. The large of land use/land cover which is consistent with the designation is 6.352,2 Ha, undeveloped consistent is in the amount of 5.300 Ha, while the inconsistent is in the amount of 41,6 Ha. The 5 greatest inconsistency occurred in the area should be designated as an agricultural area, but has been 11,3 Ha settlement. Bogor City has 7 villages which belong to the hierarchy I, 22 villages belonging to the hierarchy II, and 39 villages belonging to the hierarchy III. Based on the calculations of data, the large percentage of Bogor City green open space is 46,6% where the area with the hierarchy I has the RTH by 3,4%, 11.4% hierarchy II, and 31,8% hierarchy III. While connected to the level of inconsistency, the region of hierarchy I, there are inconsistencies in large of land use/land cover of 0,2%, 0,3% hierarchy II, and hierarchy III by 0,4%.

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.
