Judul: Penjadwalan Produksi Roti Manis di PT Nippon Indosari Corpindo dengan Menggunakan Metode Heuristik
Abstrak: Creating an efficient production scheduling was one of possible ways to maximize profit. The scheduling method mentioned above could be obtained via Integer Nonlinear Programming (INLP) and the heuristic method. This study aimed to apply an efficient production schedule via minimizing the production time (makespan) in production of the sweat bread in the PT Nippon Indosari Corpindo. The data set used in this research were primary and secondary data types, obtained from the company. The variables being measured in this research was the maximum time required in the production process of the bread. The method used was an application of the heuristic method. The results showed that the total process time obtained in the simulation was shorter than the existing schedule. The time was 1248 minutes long, which is 72 minutes more efficient than the schedule, currently applied in the company. This was due to the shorter setup time and more efficient distribution of the sweat bread for the customers.

Judul: Audit proses produksi roti manis isi di PT Nippon Indosari Corpindo Tbk. Cikarang, Bekasi
Abstrak: Nippon Indosari Corpindo Co. Ltd. is a company engaged in the manufacturing industry produced bread "Sari Roti". To maintain the quality of bakery products in order to remain in accordance with quality standards set by the company, needed a quality system process of production that work well. The purpose of this study are to identify the factors that caused deviations of quality sweet bread products by conducting an audit approach and advise the company in product quality improvement through the improvement of production processes. Data collection and processing acquired by using the seven tools quality control, including: check sheet, stratification, Pareto diagram, and cause and effect diagram. As results of observations, there are seven types of defects found in the sweet bread production process, such as dents (37%), bubbles (7%), burning (2%), leaking (5%), shape (13%), attached (15%), and others (20%). Quality improvement priorities is carried out on the kind of dent quality deviations on sweet bread. Dents on the sweet bread caused by the equipment used still manually and limited, side of conveyor pressing the edges of bread; operators who are less skilled, uncareful, and fatigue when putting bread into the conveyor; depanning methods are not effective and work instructions/SOP is less to explain about the procedure of putting the bread properly. Trial improvements designed to improve the system of production processes currently running. As a result, the trial was able to reduce the amount of dents on the sweet bread of 69.79%.

Judul: Leukemia pada kucing
Abstrak: Leukemia pada kucing adalah suatu penyakit yang sangat patogen, disebabkan oleh sejenis virus. Virus ini dikenal sebagai Feline Leukemia Virus atau FeLV. FeLV ini oleh beberapa ahli dikatakan hanya bersifat ganas pada hewan kucing. Penularannya bisa secara horizontal maupun congenital. Kucing pada semua tingkat umur dapat terserang oleh FeLV ini. Khusus pada bentuk "thymic leukemia", virus ini hanya menyerang anak-anak kucing berumur diba- wah 1 tahun. Kucing-kucing liar atau yang tidak terpeli- hara jarang sekali terinfeksi FeLV. Selain dari serangan virus FeLV itu sendiri, maka penyakit leukemia ini bisa disebabkan oleh beberapa fak- tor yang sudah ada dalam tubuh hewan dan sangat menunjang perkembangan penyakit ini, yaitu antara lain tumor, agen toksik, cedera oleh kecelakaan dan gangguan hemopoiesis. FeLV menyerang sel-sel darah dalam tubuh hewan se- hingga pembentukan darah berjalan tidak normal. Terlihat sel-sel darah yang belum dewasa sudah beredar dalam sir- kulasi darah. Bentuk dan jumlahnya tidak lagi seimbang dalam tubuh hewan kucing tersebut. Gejala klinis antara lain kekurusan, ikterus, anemia, lemah, anoreksia, dyspnoe, sulit menelan, batuk, dan membran mukosa pucat. Selain itu kelenjar pertahanan tubuh juga membengkak, kemudian terjadi hepatomegali, spleenomegali dan pembengkakan pada ginjal. Terbentuk massa tumor pada beberapa tempat. Secara biopsy pada sumsum tulang akan terlihat be- berapa perubahan. Sumsum tulang berwarna merah tua atau abu-abu. Konsistensinya lunak dan terdapat banyak sekali memproduksi sel darah putih. Melalui gambaran darah leukemia ini lebih mudah didiagnosa. Jumlah retikulosit rendah sekali. PCV 8-15%, hemoglobin menurun, sel darah putih (WBC) meningkat, lim- fosit meningkat, Alfaglobulin juga ada peningkatan, dan banyak eosinofil yang belum dewasa beredar dalam darah…dst
