Judul: mempelajari aspek HACCP dalam penanganan susu pasteurisasi di unit pengolahan Fakultas Peternakan IPB, Bogor
Abstrak: The increasing knowledge and awareness of human being to life healty gives a significant impact to industrial world, especialy food industry. Beside having a high nitrition value, consumed foods are expected to be safe for human healt. HACCP system application is useful not only for costumer but also for industry. Those usage are improving consumer reability and product safety assurance; to prevent market loss; to prevent product withdrawal and exceeding cost or to prevent loss by product safety problems. IPB Animal Science Faculty Processing Unit is one of food prcessing industry that focus on raw milk handling and prcessing with pasteurization milk as the main product. With the incresing of its businness scale, there fore it needs a quality standartization wich can fulfill food safety criteria. HACCP is a system made to assure that food safety has been done effectively, so that the concept needs to apply on Dairy Science Processing Unit. The observation activity was caried out in the Milk Processing Unit for two mont, starting from May 15th, Juli 20th, 2006, by using a participation working method, wich include a direct observation and operation in the production, general and personel section. This research showed that the lack of production facilities and employer laowledge has becaome a limitation for processing unit to apply GMP and SSOP correctly as basic requirment of HACCP. Aplication of HACCP plan and system improvement in the processing unit will assure food safety quality. It's need to arrange the best HACCP plan after the GMP and SSOP worked correctly by simplifying the allready present CCP. A more simple CCP implementation process will simplify technical aplication.

Judul: Evaluation of the Application of Hazard Analysis Critical Control Point (HACCP) at the D'lifa Yoghurt Processing Unit
Abstrak: This study aims to evaluate the application of basic feasibility and develop a Hazard Analysis and Critical Control Point (HACCP) design in the yoghurt processing process from receiving raw materials to product storage in the yoghurt processing industry. This research will be carried out at the D'lifa Yoghurt Processing Unit, Dramaga District, Bogor Regency. The analysis used in this research is descriptive to describe directly the situation in the D'lifa Yoghurt Processing Unit, Dramaga District, Bogor Regency. The data collection method in this study was data collection using observation and interview techniques to determine the yoghurt processing process. Data collection was carried out by looking at the conditions in the D'lifa Yoghurt Processing Unit. The design of this research is non-probability sampling with a scoring technique that determines the sample based on related information at the Livestock Processing Unit, Yoghurt Processing Unit D'lifa, Dramaga District, Bogor Regency. The results obtained in the GMP assessment of the basic feasibility analysis get a good average score. In the processing process there are still deviations that occur due to microbes but can still be controlled, so that it does not cause harm to food safety in yoghurt products.

Judul: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
