Judul: Respon masyarakat lokal atas kehadiran industri pengolahan tahu (studi kasus: kampung Cikaret, kalurahan Cikaret, kecamatan Bogor Selatan, kota Bogor, Jawa Barat)
Abstrak: Agro-industry is an industry which has activities that processing the agricultural products into value product. Tofu processing industry is one of the small-scale agro-industry that process soy as into the agricultural food products called tofu. The purpose of this study are to explain the public respons against the socio-economic and socio-ecology about the presence of tofu processing industries in Kampung Cikaret. Public respons about the presence of tofu processing industries in the region is seen based on the layer of households that were made by the calculation of household income structure. This research method used a quantitative approach supported by qualitative approaches. Primary data was obtained through direct interviews and questionnaires. Secondary data obtained through the documentation and study of literature. The data has been generated and then processed using cross tabulation and descriptive analysis. The analysis unit in this study is the household, to obtain data on income levels and health levels. The interview was done to the head of household to obtain data on opinions about the presence of tofu processing industries in Kampung Cikaret. The selection of respondents used simple random sampling by focusing on one location of Kampung Cikaret. The choice of location was based on a homogeneous society who lived on the outskirt of the river and use it. The research showed that the social, economic and socio-ecology point of views for the presence of tofu processing industries in Kampung Cikaret are affected by the layers of household respondents. Respondent’s opinion about the economic aspects were researched by the work opportunities in tofu processing industries in the local community. There were only a few respondents said that there are work opportunities for local people. In the social aspect of opinion of respondents about the level of competition with immigrants for work in the tofu processing industry. There were a few respondents who claimed that there was competition between immigrants and local communities to work on tofu processing industries. The respondents in the top layer, middle layer and bottom layer stated there is no competition with local communities to work in tofu processing industries. the dominant respondents stated that the social relations between migrants and the local community are good. The socio-ecological impacts of the pollution level of river conditions are seen both before and after the presence of tofu processing industry. Respondents have the opinion that before the presence of tofu processing industry in the region, the rivers were clean, but after the presence of tofu processing industry in the region, the river is not as clean as before. The river which is become one of the quality water source used by local communities was appearing the opinions about the pollution levels of the water sources over the presence of tofu processing industry. Beside that, there are opinions about the comfort level of living and health. When it comes to household’s health level, only two respondents who said that they had itching experience caused by interact with the river that has been polluted by tofu waste. Levels of conflict about the smell and polluted water sources, are

Judul: Kajian Penerapan Strategi Produksi Bersih Di Sentra Industri Kecil Tapioka : Kasus Kelurahan Ciluar, Kecamatan Bogor Utara
Abstrak: The centralization of small scale industry has caused accumulation of industrial wastes being able to pollute the surrounding environment. One of centralization of small scale industry having the potential to cause environment problems is tapioca industry. One of tapioca small industry centers in Bogor can be found in Ciluar, North Bogor Sub-District. Environment problems as the impact of industrial activities can be solved by applying cleaner production strategy. Cleaner production is aimed to increase the efficiency of material usage and minimizing wastes, pollution, and environmental risks directly to the source. This research was aimed to study (1) the potentials of cleaner production application and industrial environment management, (2) to formulate alternatives of the cleaner production strategy for centralized small scale tapioca industry in Ciluar. The data being used consists of primary data (field observation, interviews, and questionnaires for experts) and secondary data. The implementation of cleaner production was analyzed based on technological, financial, and political aspects. The method of analysis being used was AHP (Analytical Hierarchy Process). The centralized small scale tapioca industry in Ciluar produces crude tapioca to be sold to tapioca sieving industry. The solid wastes being produced is dried (onggok) to be sold. Meanwhile the waste water is drained to river without treatment. The suggestion for improvement activities consist of good housekeeping (worker training, water usage monitoring); increasing the rendemen with gobegan, keeping the quality by washing settling tanks everyday, and workers monitoring. Those activities need Rp.10.052.000 of capital with PBP 1 year and 7 months. AHP analysis resulted in the recommendation to maximize crude tapioca production efficiency by applying cleaner production has denoted that technology (0,434) is the most important factor, followed by capital (0,377) and regional government policy (0,189). The priority of cleaner production program is socialization and training of cleaner production application (0,429), integrated waste management (0,328), and socialization and training of crude tapioca quality increasing procedures (0,243). The strategy of cleaner production implementation consists of: (1) socialization and training of cleaner production by: a) increasing the awareness and motivation of businessman in maintaining environmental quality, b) accompanying group development; (2) accelerating production efficiency, (3) increasing the role of government; (4) increasing vocalism of tapioca producer in Ciluar.

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
