Judul: Accessibility to economic activities using geographic information system in DKI Jakarta Province
Abstrak: The urban spatial structure basically considers the location activities as well as their relationship. Accessibility interprates systematic relationship between spatial distribution and the intensity of development, and the quality of travel within a region. This study appraises the accessibility to economic activities for different socio-economic group, with specific reference to work trip in the Jakarta Metropolitan city. Accessibility has become a part of transport planning discusion but it is nor part of traditional transport model, therfore, it lacks formal definition. The research was conducted in three part. The fisrt step, theoretical aspect of accessibility and its measurement were reviewed. Second step, data was collected during fieldwork both from primary and secondary data. Third step, accessibility analysis was done to appraise the level of accessibility. Results of the analysis shown that high-income area that located around the main CPA (Centers of Primary Activity) as well as Glodok Primary Centre, Tanah Abang Primary Centre, Kuningan Sudirman and Casablanca Trade Center, and Mangga Dua Trade Center. Then come middle-income area followed by the low- income suburbs. Investigation of distribution of economic activities shows that the city having centralised form in the past has experienced decentralisation. Still it is concentrated in high-income suburbs. Travel pattern of commuters in two sample areas reveals that bus, rail and taxi are the available modes of public transport, which are mostly used by low and middle-income suburbs. Use of multi-modal transport not found in the study area. High-income suburbs are highly dependent on car. Crime on public transport is the major factor to deter the high-income groups from using it. Walk as a mode is done by low paid job living in nearby area of the activities. Result from proximity analysis highlights that low and middle-income can access public transport better than high-income suburbs on average. Taxi serves maximum arsa followed by bus. Rail service is concentarted in limited areas. The percentage of low-income suburbs which can have access to the activities by public transport is compared based on income, in spite of having better access to public transport to low-income suburbs, people can access very low percent of the activities on average within the standard considered for this study. Middle- income suburbs can access more than low-income group. Among the three income group, high-income suburbs can access the highest number of activities. Pedestrian of any income group have poor access, however high-income suburbs lead in this aspect also. It is concluded that the results strengthen the argument that there is imbalance in uistribution of activities. Provision of integrated fare structure may improve the accessibility especially for low and middle-income suburbs. Pedestrian accessibility result highlights how activities are concentrated in Centers of primary Activity (CPA) nodes. Finally, transportation is not the sole factor that affect the accessibility but the distribution of activities has also influenced it.

Judul: Analisis Perubahan Penggunaan Lahan Pada Berbagai Kelas Kemampuan Lahan Dan Keterkaitannya Dengan Aksesibilitas Menuju Pusat-Pusat Pertumbuhan (Studi Kasus Sub DAS Ciliwung Hulu, Kawasan Puncak-Bogor)
Abstrak: Along with Depok, Tangerang, Bekasi (DETABEK), Regency and Municipality of Bogor are located near Jakarta (for about 60 km), hence are influenced economically from Jakarta's growth. It implies that BODETABEK serves as Jakarta's suburban and is known widely as the buffer. These areas are reserved to accept overflows of investment on economic development of Jakarta. The areas are supported by their contiguous spatial setup with enhanced access such as primary road networks and highways. This amenity is shown by duration of travel between Bogor and Jakalia which takes less than 1 hour and therefore attracts people who takes jobs in Jakarta to reside in Bogor. Results of remotely -sensed image classification indicate that the biggest conversion occurs in paddy field areas which decreases to 13,72 % and forested areas which decreases to 43,2 % from previous state (year 1991 - 2001). Urbanized areas rise up to 14,66 %. Classification of land capability shows that Class VI acreage is about 441,43 Ha. It is shown that most ofland utilizations are used inappropriately in comparasion to their actual capabilities. Employing Hayashi 2 (Axis 1) and Multinomial Logit, we find similar results between both of them. Andisols; Climate of III C; Slope class of 8 - 15 %; and the second grade of land capability is the most influencing factors. Instead we also find inconsistencies of the results from both. Distance to nearest roads and its growth centers is the most influencing factor to land use change. On analysis of Hayashi 2 (Axis 3) and Multinomial Logit, we find that the most influenced factor is land capability and distance nearest roads and to growth centers . Scatterplot was employed to illustrate patterns between land use changes, III particular for the conversion patterns of the Forest-Upland Field, ForestSettlement, Forest-Paddy Field, Paddy Field-Upland Field, and Upland FieldSettlement and their relations to four types of distance setup: to nearest roads, to Bogor CBD, to Jakarta CBD, and Cipanas CBD. There are no such patterns observed in this research. Further, conversions, are indicated to all areas regardless of the distance to both growth centers or road networks.

Judul: Perancangan Proses Produksi Telur Asin Rendah Kolesterol
Abstrak: Telur asin merupakan produk olahan telur yang digemari masyarakat, tetapi mengandung kolesterol yang melebihi batasan konsumsi harian manusia. Tahap pengolahan, telur asin direndam dalam larutan khusus guna menurunkan kandungan kolesterol di dalam telur. Proses ini melibatkan pengaturan waktu pemeraman, konsentrasi larutan, dan bahan-bahan lainnya untuk mencapai hasil yang diinginkan. Formulasi telur asin yang terpilih yaitu pemeraman selama 12 hari dalam larutan garam 32,5% yang dicampur bawang putih, sereh, dan daun jeruk cincang, perendaman dalam larutan soda 20% selama 4 jam, dan dikukus selama satu jam. Kadar kolesterol sebesar 233,39 mg/100 g pada hari pertama dan mengalami penurunan menjadi 131,61 mg/100 g pada hari kesepuluh., Salted eggs are a popular egg product among the community, but they contain cholesterol that exceeds the daily human consumption limit. In the processing stage, the salted eggs are immersed in a special solution to reduce the cholesterol content inside the eggs. This process involves adjusting the soaking time, solution concentration, and other ingredients to achieve the desired results. The selected salted egg formulation is marinating for 12 days in 32.5% salt solution mixed with garlic, lemongrass, and chopped lime leaves, marinating in 20% soda solution for 4 hours, and steaming for one hour. The cholesterol level was measured at 233.39 mg/100g on the first day and decreased to 131.61 mg/100g on the tenth day.
