Judul: Geographic Information System for Occupational Health  and Safety (OHS) Risk Mapping
Abstrak: Kecelakaan dapat terjadi kapan saja, di mana saja, dan kepada siapa saja. Namun, risiko tersebut dapat diminalisir dengan penerapan program keselamatan dan kerja. Keselamatan dan kesehatan kerja (K3) menjadi suatu hal yang wajib dipenuhi oleh setiap perusahaan. Sistem Informasi Geografis (SIG) dapat menjadi perangkat yang sangat membantu dalam perencanaan dan pembuatan kebijakan terkait K3. SIG digunakan untuk memetakan dan memvisualisasikan risiko kecelakaan dan penyakit, mengidentifikasi penyebaran penyakit, serta melakukan pemantauan dan pencegahan kecelakaan dan penyakit. PT Nayotta Kelola Laut Indonesia merupakan perusahaan agroindustri yang bergerak pada bidang perkebunan, perhutanan, dan secara terkhusus perikanan. Perusahaan ini memiliki area kerja yang cukup luas dengan karakteristik lingkungan kerja yang berbeda di kawasan-kawasan tertentu. Penelitian ini merancang SIG untuk pemetaan risiko K3 di PT Nayotta Kelola Laut Indonesia. Metode yang digunakan pada penelitian ini adalah Hazard Identification and Risk Analysis (HIRA) dan analisis semi kualitatif. Hasil penelitian menyajikan analisis risiko kerja yang diimplementasikan ke dalam SIG, yang memberikan informasi lokasi-lokasi potensi bahaya dari aktivitas kerja beserta tingkat risikonya.

Judul: Analisis Keselamatan dan Kesehatan Kerja (K3) Pada Industri Pengolahan Teh (Studi Kasus Pada Bagian Produksi PT. Sinar Inesco, Tasikmalaya)
Abstrak: The problems in Occupational Safety and Health frequently still are ignored. This matter is shown with the number of work accident remain high. Based on data recorded in PT. Jamsostek, there were 83,714 work accident cases in Indonesia within year 2007. This number includes 6,506 handicaps, and 1.883 deaths. Agriculture is one of the most hazardous occupations in worldwide. In several countries the fatal accident rate in agriculture is two times higher than the average for all other industries. PT. Sinar Inesco as one of agro industry has quite intense activity involving labors, appliance, method, expense, and the material and also full time daily work. That condition owns the possibility of the happening of risk or hazard even accident in activity execution. This research was aimed to study potential hazard in working environment, to know the risk level in each hazard, and to identify the factors dealing with Occupational Safety and Health. Risk assessment used qualitative analysis which generally known as 2D model, where risk level was calculated from multiplication of Likelihood with Consequence which was reconciled with matrix table of risk analysis 2D model. Risk level showed by the matrix was then used define control techniques in accordance with literature and condition of location. Identification resulted that hazards at production activity of tea processing were classified into 4 units e.g. pre-withering and withering, hulling and fermentation, drying, sorting and packing. Hazards with low risk levels are slumped, incurred by heat from fan, collided by chair monorail, the noise (at pre withering and withering unit), slipped (at hulling and fermentation unit), clamped in drying door (at drying unit), dust breathed by respiration, noise and collided (at sorting and packing unit). Hazard with medium risk level was included scratches (at pre withering and withering unit), fallen down, electricity shocked, noise (at hulling and fermentation unit), hot exposure and slipped (at drying unit), clamped in enchain, eye incurred by dust and electricity shocked (at sorting and packing unit). The last level is high risk. This kind of risk has to be reduced before continuing work. Hazard with high risk level consist of pulled by propeller, and electricity shocked (at pre withering and withering unit), clamped, cut (at hulling and fermentation unit), fallen down, burned, noise (at drying unit) and pulled by propeller (at sorting and packing unit). Observations indicate that the cause of hazard can be grouped into two, that is, unsafe action done by worker and unsafe condition. Unsafe action done because the workers have less knowledge about Occupational Safety and Health. Unsafe condition commonly caused by destroying equipments such as production machines and the working safety equipments Each hazard has different risk levels; therefore, different control techniques are suggested. Control which can be done in general is to frame Standard Operation Procedure (SOP), to use personal protection, display, as well as to repair damaged equipments and machine. Control can be used by all hazards for low, medium and high risk while the extreme risk has to be eliminated.

Judul: Apatite Growth Optimation on Chicken Mucouse by Fourier Transform Infrared (FTIR) Characterization
Abstrak: Some experiment had been conducted to grow apatite from supersaturated solution of calcium phosphate ions on chicken mucouse. The calcium and phosphate ions were originated from Ca(NO3)2 and (NH4)2HPO4. Carbonate ions from (NH4)2CO3 was also used as starting solution. Experiment was carried out within about 5 hours at temperature 370 C and pH 7. Value of Ca+ : PO4 3- was 1.67, while molar ratio of CO3 2- : PO4 3- was 0.5 : 1. Molarity of molar ratio CO3 2- : PO4 3- variated approximately 0.15 : 0.30, 0.51 : 1.02, and 0.90 : 1.80. Mass of mucouse powder was constant 0.75 gram. The analysis result of Fourier Transform Infrared (FTIR) showed that the precipitation was apatite carbonate type A and B. In these experiment it was found out that the mucouse reduce the crystallinity of apatite precipitant, and the growth of apatite crystal was optimum at solution with molar ratio CO3 2- : PO4 3- about 0.15 : 0.30.
