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.

Abstrak: Sistem perdagangan yang semakin ketal dan kompetitif serta penerapan pasar bebas di era g10balisasi menuntut peningkatan kualitas produk suatu perusahaan agar dapat memenangkan kompetisi dengan perusahaan lain. Keamanan pangan merupakan hal serius yang menentukan kualitas produk. Untuk memenuhi tuntutan ini maka dikenal suatu sistem pengendalian bahaya yang dikenal dengan nama HACCP. HACCP adalah suatu sistem yang mengidentifikasi bahaya spesifik yang mungkin timbul dalam mata rantai produksi makanan dan tindakan pencegahan untuk mengendalikan bahaya tersebut dengan tujuan untuk menjamin keamanan pangan.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
