Judul: Penjadwalan Transportasi Tandan Buah Segar dan Tandan Kosong Kelapa Sawit (Studi Kasus di PTPN VIII Kertajaya Banten)
Abstrak: Transportation scheduling nowadays has been considered as one of important factor in efficiency of an industry production system. In a context of oil palm industry, transportation scheduling is in charge of implementation of fresh fruit bunch transportation from the field to the factory, and empty fruit bunch, as by product of fresh fruit bunch processing in factory, to the field. Research in PTPN VIII Kertajaya was done in order to meet optimization of transportation resource allocation. Transportation scheduling was implemented by considering crop scheduling and factory process scheduling. This transportation model scheduling consists of three sub models: production forecasting, crop route, and vehicle number. Data of daily production in January and February 2011 was simulated in a fit distribution and used as the basic of daily production forecasting in March 2011. Fresh fruit bunch production forecasting was used to decide the crop route, which was trip number needed to collect all fresh fruit bunches in all filed divisions. All trips needed and production time provided were input of vehicle number calculation, then these trips were scheduled in each time unit. Model validation used sMAPE and MAPE tests. Fresh fruit bunch forecasting resulted 159%, 95%, 67%, and 51% of sMAPE value for each Division 1, Division 2, Division 3, and Divison 4. It is better than current one used in the company which results 161%, 138%, 77%, and 65%. MAPE value for empty fruit bunch production forecasting is 23.41% and vehicle number forecasting is 12.43%.

Judul: Sistem Penunjang Keputusan Penjadwalan Transportasi Angkut Tebu (Studi Kasus PG Rajawali II Unit Jatitujuh Majalengka)
Abstrak: One problem that happened in production’s process at PG Rajawali II Unit Jatitujuh is that total of sugar cane the company could get after sugar cane has been cut off is not the same with the logging plan that has been made. Transportation scheduling program CaneTrans made to decrease the amount of idle time of sugar cane and truck when sugar cane transportation from plantation to factory is being progress. Transportation scheduling and the total of truck needs is the output that CaneTrans resulted and it is updated everyday based on logging plan. Times, distances of plantation to factory, and weather used as variables which can influence the result of transportation schedule program. Total of the needs of truck is the best result of the truck needs that adapted with the result of transportation scheduling. To get more valid transportation schedule, queuing analyze has been done at unloading station. The results of the analysis shows that the queuing model formed at station A is M:M:1:FCFS:F with 58 minute of queuing time and queuing model at station B is M:M:1:FCFS:I with 48 minutes of queuing time. Efficiency for the average of sugar cane that can be transported by each truck is increased after compare result of the program with the actual data on May 25th, 27th, 29th, and 31st, the efficiency is resulted 114,19%, 102,8%, 104,1%, and 113,26% where all of sugar cane that has been planned to transported from plantation to factory can be taken with fewer of total of the truck needs than the actual data.

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
