Judul: Penentuan Kapasitas Optimal Produksi CPO (Crude Palm Oil) Di Pabrik Kelapa Sawit PT. Andira Agro Dengan Menggunakan Goal Programming
Abstrak: Permintaan minyak kelapa sawit kasar (CPO) di Indonesia semakin meningkat dari tahun ke tahun. Pihak-pihak yang berkaitan dalam produksi CPO memerlukan suatu usaha tertentu agar proses produksi berjalan baik dan sesuai dengan sumberdaya yang tersedia di pabrik guna mencukupi permintaan konsumen. Penggunaan barang dan modal yang optimal dapat meningkatkan efisiensi dan efektivitas operasional pabrik dan juga mendukung mutu produk. Salah satu usaha yang dapat dilakukan adalah dengan perencanaan produksi CPO yang baik. Perencanaan dapat dilakukan dengan metode matematik program sasaran linier (linear goal programming). Penelitian di PT. Andira Agro bertujuan untuk (1) mengetahui faktor-faktor produksi yang terlibat dalam perencanaan produksi CPO, (2) mendapatkan tingkat kapasitas produksi yang optimal dengan menggunakan program sasaran linier. Ruang lingkup yang dikaji dalam penelitian ini terbatas pada keadaan yang berpengaruh pada pencapaian optimasi produksi CPO, khususnya kegiatan di kebun untuk menghasilkan Tandan Buah Segar (TBS), yang merupakan bahan baku utama CPO, dan kegiatan di pabrik untuk menghasilkan CPO.

Judul: An Aggregate Production Planning Model With Dynamic Programming Approach for Palm Oil Industry
Abstrak: A common challenge in fulfilling the demand of the raw material requirement is a continuous and repetitive work in a CPO based industry. Main type of operations and procurement in this work lead to how to identify factors that affect the Aggregate Production Planning (APP) system in a CPO based industry. The objectives of this work including how to construct the forecasting model of raw material supply and demands, and to develop an aggregate production planning model in CPO based industry with a dynamic programming approach, and eventually to optimize the total production cost and increase the profit. Parameters of the production process in the APP system consists of working time, productivity, production capacity, inventory level, inventory capacity, subcontract and cost parameters. The forecasted demand of CPO was computed by Additive Decomposition. The forecasted supply of raw material was computed by Multiplicative Decomposition Method. The model showed that the total minimum cost of the CPO production for a year is around Rp 126 Billion. The result of DP showed a potential forecasted profit in the next year.

Judul: Gambaran darah komodo (Varanus komodoensis) di Taman Margasatwa Ragunan
Abstrak: This study was conducted to get the hematology and blood biochemistry profile of Komodo dragons at Ragunan Zoo. A total of 18 adult dragons were used. Blood was drawn as much as 2 mL whole blood for hematology and 3 mL for blood biochemistry in serum. Hematology examinations were done by automatic hemavet® machine except differential leukocytes were done manually and blood biochemistry examinations were done by biosystem® machine. Examinations results of erythrocyte parameters of total erythrocytes, hematocrit, hemoglobin, MCV, MCH, and MCHC in row are (1,24±0,21) × 106/mm3, (38,0±4,6) %, (13,3±1,6) g/dL, (311,4±49,9) fL, (109,4±18,7) pg, and (35,1±1,2) g/dL. Trombocytes count is (3,1±1.6) × 103/mm3 and erythrocyte sedimentation rate is (3,9 ± 1.7) mm/h. Leukocytes parameters indicate the values of total leukocytes, heterophils, lymphocytes, monocytes, eosinophils, and basophils in row are (6,53±9,47) × 103/mm3, (3,478±4,972) × 103/mm3, (2,959±4,694) × 103/mm3, (0,096±0,187) × 103/mm3, (0,00) /mm3, and (0,00) /mm3. Biochemical parameters indicate the values of total protein, albumin, globulin, AST, ALT, urea, and creatinine in row are (10,19±3,39) g/dL, (2,51±0,39) g/dL, (7,68±3,07) g/dL, (49,39±20,71) IU/L, (45,39±27,88) IU/L, (13,53±5,88) mg/dL, and (0,29±0,11) mg/dL. The result of examinations averagely showed values tend to normal. Some individual results demonstrated abnormalities which are suspected as acute infection in 1 dragon, foliculogenesis in 1 dragon, muscle disease in 2 dragons, and liver disease in 5 dragons.
