Judul: Identifikasi dan Analisis Budaya Perusahaan di Pabrik SCC & C (Spread Cooking Category and Culinary) PT Unilever Indonesia Tbk., Cikarang.
Abstrak: PT Unilever Indonesia Tbk is one of manufacturing companies in Indonesia producing toiletries and food. The company realizes the importance of assessing its corporate culture in order to achieve its vision and mission. This research was conducted at The SCC & C (Spread Cooking Category and Culinary) Factory of PT Unilever Indonesia Tbk. The purposes are to assess the now and the preferred dominant culture, and to analyze the different cultural perception between management and employees. The research used survey method and using two instruments, that were Reigle’s (2003) OCA (Organizational Culture Assessment) and Cameron and Quinn’s (2006) OCAI (Organizational Culture Assessment Instrument) . The results show that using the OCA method the dominant corporate culture is an organic culture and the preferred one is to be more organic. Using the OCAI method, the culture is identified as a mix between market and clan culture. The preferred culture is to increase the clan dimension and to decrease the market dimension of culture. There is no different found between management and employee perception on current and preferred culture. This lack of perceived gap means that the company has a good potential to conduct cultural change. Based on the research findings, the company needs to focus on the management of employee. Consequently, it should improve the management competency especially in the areas of managing team, managing interpersonal relationship, and managing the development of others.

Judul: Penerapan Sistem Hazard Analysis Critical Control Point (HACCP) dan Statistical Process Control (SPC) dalam Proses Produksi Bumbu Penyedap Rasa di PT Unilever Indonesia Tbk
Abstrak: PT Unilever Indonesia Tbk built new factory, Lion, where new savoury products are produced. As one of big company who give priority to maintaining consistency and quality of products, food quality management sistem and quality control of process is very important to do. The purpose of this research is to apply HACCP system and SPC in monitoring the Aw quality of the product. The HACCP implementation methods used consisted of pre-requisite program HACCP study, and HACCP Plan preparation based on five steps and seven principles of HACCP and The SPC methods used consisted of observation and identification of problems, brainstorming, control chart, fishbone diagram, Pareto diagram and action plan. Based on the identification and determination of CCPs of HACCP, there are four groups material that are categorized as OPRP and one OPRP in the process. There is one CCP on filling process, which the product passed through a metal detector machine to prevent contamination of foreign matter in the form of metal. The conclusion of identification problem brainstorming is Aw out of standard spesification. measurement results of samples 252 batch using i-chart indicating that the process is out of control. Using fishbone diagram, why why analysis and pareto analysis,the causes of Aw problem were analyzed. it was observed that there were four main problems contributed to 82,5% causes of this case includes RH of packing hall outside the standard (25%), semi-finished goods packaging products during the process of filling opened (25%), RH of dehumidifier outside standard (25%), and unloading time (7.5%).The action plan such as material handling monitoring along the process has been implemented to solve the problems.

Judul: Dynamical System of Hepatitis B in Three Groups with Vaccination
Abstrak: The aim of this study is to modify the hepatitis B transmission model in three age groups involving vaccination from the model conducted by Zhoe and Zhang.The method used is to analyze the stability of the fixed point and its basic reproduction number (R_0). Performed stability analysis and numerical simulation to see population dynamics. Next, a sensitivity analysis of the parameters was carried out to see its effect on R_0. From the analysis obtained two fixed points, namely non-endemic and endemic fixed points. Non-endemic fixed points are locally asymptotically stable if R_0 <1 Meanwhile, the endemic fixed point is locally asymptotically stable if R_0 > 1. Hepatitis vaccination affects the number of susceptible population, because the more successful the vaccination, the smaller the number of susceptible populations so that the smaller the population will be infected.
