Judul: Studi Waktu pada Aktivitas Pemanenan Kelapa Sawit di Perkebunan Sari Lembah Subur, Riau
Abstrak: Optimization of work productivity is needed by company. Optimum products will increase the company's profit. Productivity can be improved by method of working, time study, and salary. Working methods need to be studied in order to reduce fatigue of work so the time needed to produce a product becoming decreased. The aim of the research is to determine elements of work on oil palm harvesting activities based on patterns of working time, determination time standard on elements of the work in activity of oil palm harvesting. Research stage in oil palm harvesting activities were introduction, data collecting, data processing, and improvement. Standar time for verify the maturity of fruit (Ve) on terrace topography (T)- dry land (K)-the height of trees 0-3 m (H1) is 3.21 second, Ve on T-K- the height of trees 3-6 m (H2) is 2.39 second, Ve on flat topography (F)-K-H1 is 3.45 second, Ve on F-K-H2 is 4.59 second, Ve on F-wet land (B)-H1 is 4.27 second. Standar time for prepare harvesting tool (Pr) is 6.45 second. Standar time of cutting the fruit and stem of (Cu) on the T-K-D is 29.86 second, Cu on T-K-E1 is 38.47 second, Cu on T-K-E2 is 57.91 second, Cu on F-K-D is 14.19 second, Cu on F-K-E1 is 25.88 second, Cu on F-K-E2 is 21.06 second, Cu on F-B-D is 21.13 second. Standar time for moving the stem (Ba) is 9.53 second. Standar time for cutting the stalks (Ck) is 1.74 second. Standar time picking up the fallen fruits “brondolan” (Br) on T-K-H1 is 51.48 second, Br on T-K-H2 is 20.32 second, Br on F-K-H1 is 37.03 second, Br on F-K-H2 is 51.75 second, Br on F-B-H1 is 29.67 second. Standar time for loading fruit (Lo) is 3.75 second. Standar time for moving by carrying empty “angkong” (UDA) of 9.39 second, moving by carrying fruit (MoT) is 8.68 second, moving by carrying fruits and “angkong” (MoAT) is 13.52 second, moving (UDK) is 15.07 second. Standart time for unloading (Un) is 6.56 second. Standar time for avoidable delay is 10.83 second.

Judul: Studi Waktu dan Aplikasinya untuk Optimasi Tata Laksana Kerja Pemanenan Kelapa Sawit di Perkebunan Pasang kayu, Sulawesi Barat.
Abstrak: Working time of palm oil harvesting vary greatly in settlement, which will affect harvest quality and productivity of work. The purpose of this study wasto determine the standard time, the capacity of harvesting based on the standard time and to determine of harvesting working procedure based on sequential optimization elements of harvesting work. Results of the study showed that the harvesting time was influenced by the working conditions, such as tree height and land topography. Therefore, its necessary for time adjustment to working conditions. Work elements that require adjustment to the working conditions were the time element of Ve, Pr, Cu and Br. Time of harvesting on flat land was relatively shorter than the time of harvesting on rolling land. Meanwhile, the tree height affect the length of harvesting time. A better working procedure for harvesting oil palm way obtained by conducting empty displacement activities and identify ripe fruit simultaneously, and adapting cutting technology of rod cluster

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.
