Abstract

The upper stream of Ciliwung watershed lies in Bogor District, has an important function for the surrounding areas, which regulated or managed water supply, whether floods or drought in the middle and the down stream. Growing of settlement areas was changed landscape and degraded environment, and then this is threated sustainability of setlement areas. Sustainability of Settlement areas in Upper stream of Ciliwung Watershed are impacted by internal and external factors. The objective of this research the first is to analyse sustainability of settlement areas in upper stream of Ciliwung Watershed. and the second is to analyse factors that impacting sustainability of settlement areas in the upperstream of Ciliwung watershed, The research method used Multi Dimentional Scaling (MDS) technique with Rapfish software. The research result showed that settlement areas in Upper stream of Ciliwung watershed are less sustainable, with 16 factors that impacting this sustainability.Keyword : Ciliwung watershed, sustainability of settlement areas.

Abstract

This research aims to examine the differences between animal food consumption in urban and rural areas in Indonesia using discriminant analysis. The data used are secondary data obtained from the National socio-economic Survey (Susenas) held Central Bureau of statistics of the year 2015. The data analyzed includes data on average consumption of protein (grams) per capita a day according to the dining area and group housing in 34 provinces in Indonesia. Animal food consumption are examined, namely fish consumption, the consumption of meat, eggs and milk consumption. Based on the results of the analysis it can be concluded that the normality test, matrix test of the variety of uniform and test the average vector value is fulfilled, so the discriminant function is obtained as follows: where is consumption of fish, is the consumption of meat, eggs and milk consumption was and is the value of the discriminant score. The result of the discriminant functions that form validation indicates that the function is accurate and stable. The precision of the discriminant function was 85.08% or there are 2 errors in classifying a group of villages and 8 errors in classifying a group of 67 regions of cities and villages throughout the province in Indonesia. Based on the magnitude of the coefficients of the function, that the consumption of eggs and milk that contributes the largest animal food consumption differences across cities and villages.Key words : animal food consumption, discriminant analysis, test validation, assumptions

Abstract

Coconut processing industry produces a by-product or shredded coconut husks limbahberupa. The main advantage of the dregs of coconut food fiber is high, which proved instrumental in the prevention and control of various chronic diseases such as colon cancer, heart attack, hypertension, stroke and diabetes mellitus. This research aims to produce products made from flour, coconut dregs have a good nutritional quality and food high in fiber so it is expected to become a functional food ingredients. This research use the sample waste dregs of coconut derived from shredded coconut seller in the traditional markets of coconut husks and waste from industrial Virgin Coconut Oil (VCO), then waste coconut husks that are washed, boiled, dried and milled into flour so that the coconut husks. Based on data proksimat the flour coconut pulp market has food and fiber carbs are lower while levels of protein, fat and vast grounds higher than the flour coconut husks VCO.Analysis of microbiological by-product of coconut flour shows VCO has sanitation and food security is better when compared to the dregs of coconut flour market.Key words: Waste, Coconut Dregs Of Flour, Proksimat, Microbiology

Abstract

Study of utilization of Natural Zeolites Active-Mo (Mo-ZAA) as a catalyst and influence of temperature variation on hydrocracking product temperature hydrocracking has done. Castor oil hydrocracking process done with a variation of the temperature of 250oC, 300oC, 350oC, 400oC, 450oC, 500oC and 550oC, flow rate of hydrogen gas 3.5 mL/minute and weighs 1.5 g catalysts. Hydrocracking castor oil products have been analyzed including the burning heat, density and viscosity by using the bom kalorimeter, picnometer and Ostwald viscometer instrument. The results of this study showed that the best value of the burning heat, density and viscosity in a row is on the 53.0003 kJ/g; 0.9698 g/mL and peace of 3.1691, each of which is operated at a temperature of 350oChydrocracking. Using the Mo-ZAA as a catalyst also plays a role in the process of hydrocracking. This can be seen from the value of the heat of combustion, the density and viscosity of castor oil hydrocracking product is better than the heat of combustion, density and viscosity prior hydrocracking.Key Words : Hydrocracking, Catalyst, Active Natural Zeolite, Castor Oil

Abstract

This study aims to determine the species of ground cover plant as well as important value index, the level of species diversity and distribution pattern of ground cover in Nature Reserve and Nature Park of Telaga Warna. This research used the transect method and data collection were using field observation technique. The area of observation consists of three locations with different altitudes including 1400, 1500 and 1600 m asl. Each location is made of three transects that lengthwise the topography. Each transect consists of 10 sample plots measuring 1 x 1 meter with transects spaced 10 meters. Ground cover plant are found as many as 28 species consisting of 20 families. Based on the Important Value Index/INP, obtained the species that dominates at 1400 m asl is Impatiens chonoceras, while at 1500 and 1600 m asl is Scleria laevis. Based on the index of diversity was found that the level of diversity at each location is currently abundant. Based on the index of dispersion was found that the dispersion patterns of ground cover plant at each location is clumped.Keywords: ground cover plant, Nature Reserve and Nature Park of Telaga Warna

Abstract

Sungai Ciliwung sebagai salah satu perairan umum yang mengalir melewati berbagai daerah mulai dari wilayah yang belum terganggu sampai dengan wilayah kegiatan manusia. Penelitian tentang makrozoobentos masih sedikit oleh karena itu perlu dilakukan penelitian tentang makrozoobentos. Penelitian bertujuan untuk mengetahui keanekaragaman makrozoobentos di Sungai Ciliwung. Pengambilan sampel terbagi menjadi 3 titik. Stasiun I Puncak-Cisarua Kabupaten Bogor), Stasiun II di daerah bendungan Katulampa (Kota Bogor), dan Stasiun III di Kedung Halang (Kota Bogor). Pada setiap stasiun dilakukan pengulangan sebanyak tiga kali. Dari hasil penelitian diperoleh komposisi 7 spesies dari kelas Gastropoda yaitu Elimia sp, Pila sp, Floridobia sp, Tarebia sp, Ademietta sp, Pomacea canaliculata, dan Pleurocera sp. 1 spesies dari kelas Crustacea yaitu Scylla sp dan 1 spesies dari kelas Bivalvia yaitu Corbicula sp. Keaekaragaman tertinggi adalah pada stasiun I (Cisarua) dengan indeks keanekaragaman 0,544 dan keanekaragaman yang terendah terdapat pada stasiun III (Kedung Halang) tidak terdapat makrozoobentos. Kepadatan populasi yang didapat pada stasiun I (Cisarua) yang tertinggi jenis Tarebia sp dengan indeks kepadatan populasi 0,1188 dan terendah pada jenis Pila sp yaitu 0,006. Pada stasiun II (Katulampa) tertinggi jenis Elimia sp dengan indeks kepadatan populasi 0,1188 dan terendah pada jenis Tarebia sp dan Corbicula sp yaitu 0,006.

Abstract

The Objectivie of this study was to analyze the determinants of street food safety issues and formulate of its eradicatian program. The study used Survey methods and was conducted from April to August 2012 in Padang and Serang Districts.The The total number of 96 students from Padang District and 90 students from Serang District were selected purposively.The streed food issues data was taken through focus grroup discussion of stakeholder (teachers, parents of students, vendors, and staff of the relevant agencies) and was analyzed using Interpretative Structure Modelling (ISM). The result showed that there are six determinats of street food safety issues namely: low level of street food vendor moral; a harmful additive still sold freely; coachingandsupervisiontostreet food vendorare stilllow; very low prices of harmful additives; The government still allowed the production of a harmful additives; additional ingredient dangerous; supervision on hawker food producers school children is still not a priority program
