Abstrak: The aims of this research are to identify the areas that are vulnerable to food and nutrition insecurity and, to find characteristics of food insecurity regions at sub district level in Bogor City. Based on that identification, the strategies to overcome the problems which is focused on food and nutrition issues are developed. The indicators used are poverty level lighth of roads, access to health facilities, Rasio of people per doctor to population density and percentage of malnourished children. All the indicators are analyzed by scoring method analysis; logistic regression analysis, satellite images analysis, AHP and spatial analysis. The research shows that there are three categories of food nutrition vulnerability: (a) vulnerable, (b) moderate and (c) food secure. There are 8 sub districts which are categorized as vulnerable; 23 sub district as moderate and 37 sub districts belong to safe status. The vulnerable areas (or food insecure regions) are characterized by the location of the sub district which are for from city center; the high percentage of the poverty population; the high percentage of malnutrition infant and poor quality of sanitations. The Other characteristics are the low capacity and facilities; and the low health service facilities and low quality of basic infrastructure. Based on the result and the analysis, the priority strategies to over come the problems of food insecure areas in Bogor city are regional economic development, community empowerment and improvement of human resources, facilities and health services, basic infrastructure, network development and strengthening coordination of among related parties and the development of environmentally friendly territory.

Judul: Strategy for Improving Food Security in Bogor Regency
Abstrak: Food is a basic need for every human being, especially the main staplefood, namely rice in Indonesia. In this case, the agricultural sector plays an important role in producing rice. However, the national agricultural sector is experiencing problems in the form of rice field conversion and productivity which tends to stagnate. This problem is no exception experienced by Bogor Regency. The problem is caused by population pressure and relatively high economic transformation in Bogor Regency. This problem causes rice production to be not optimal so that there is a rice food deficit and has an impact on not achieving rice food independence in Bogor Regency. This study has three objectives, namely: 1) analyzing the rate of development of rice production and the relationship between rice production, land area and productivity of Bogor Regency; 2) projecting opportunities for food fulfillment (food self-sufficiency) in Bogor Regency until 2025; 3) formulate recommendations for strategies to increase food security in Bogor Regency. The data used are primary data and secondary data. Primary data were obtained through interviews with respondents from the Food Security Service using a questionnaire. Secondary data was obtained through literature review, BPS and the Department of Food Crops, Horticulture and Plantations. The analytical method used to answer the first research objective is descriptive analysis and multiple regression. The second research objective was answered by quantitative descriptive analysis in the form of projections of food self-sufficiency in 2025. The third research objective was completed by SWOT and QSPM analysis. The results showed that the land conversion factor had no significant effect on rice production, while productivity had a significant effect on rice production. Based on the analysis of the pattern of development of rice production in Bogor Regency, the projected results of the fulfillment of rice food self-sufficiency in 2025 are obtained. The projection results show that in 2021 to 2025, Bogor Regency has not been able to meet the food needs of rice independently. In 2025, it is projected that Bogor Regency will experience a rice food deficit of 62%. The formulation of the strategy in increasing food security in Bogor Regency includes: empowering agricultural human resources, stopping land conversion, revitalizing agriculture, cooperation with other regions with surplus rice and increasing the synergy of cross-sectoral programs.

Judul: Desain Sistem Transfer Energi Nirkabel Berbasiskan Tesla Coil
Abstrak: Tesla coil merupakan alat yang ditemukan oleh Nikola Tesla yang dapat mentransmisikan daya tanpa kabel dengan memanfaatkan prinsip induksi elektromagnetik. Pada penelitian ini dibuat sebuah prototype Tesla Coil dengan menggunakan transistor C1970 dan receiver menggunakan rangkaian LC. Identifikasi alat meliputi pengaruh daya input transmitter terhadap receiver, bentuk signal yang dipancarkan transmitter, pengaruh jarak transmitter dan receiver, nilai efisiensi serta efek alat terhadap perangkat lain. Hasil pengamatan menunjukkan bahwa semakin besar daya input maka semakin besar daya yang dipancarkan oleh transmitter. Bentuk sinyal yang dipancarkan oleh transmitter berupa gelombang listrik AC sinusoidal dengan frekuensi ~2.9 MHz. Semakin jauh jarak receiver terhadap transmitter maka semakin kecil amplitudo gelombang AC yang diterima oleh receiver, menyebabkan semakin kecil daya yang diterima oleh receiver. Adapun nilai efisiensi terbesar penangkapan daya oleh receiver yaitu sebesar 0.00516 % serta terdapat gangguan pada alat-alat tertentu seperti monitor komputer dan radio.
