Judul: Desain Konseptual Knapsack Sprayer untuk Budidaya Kelapa Sawit melalui Pendekatan Ergonomi.
Abstrak: Designing a tool/machine needs ergonomics aprroach in order to match between man-machine system. One of the important tools in oil palm cultivation is knapsack sprayer. This study was conducted in aiming to understand risk occupational knapsack sprayer operation. So, ergonomic analysis is needed for these activities to understand the need of intervention to reduce the risks of working and complaints that occur. Based on Nordic Body Map questionnaire, the operator of knapsack sprayer suffered muscular fatigue and pain on the leg (28%), the left upper arm (27%) and the neck (14%). Based on the Range of Motion’s criteria, dangerous zone (Zone 3) were identified on hip flexion, shoulder flexion and neck flexion. Futhermore, REBA method was applied to evaluate the work posture in detail. The REBA revealed that score of 8 or more were resulted on “Loading”, “Pumping”, and “Spraying” work elements. These mean that the work element were high level of MSD’s risk, thus changing in the working condition is needed soon. Workload analysis found that 17 kg of total weight knapsack sprayer with the dimension of knapsack sprayer’s tank is (390 x 171 x 534) mm and pump lever length is 720 mm. Recomamanded resting time for knapsack sprayer operator is 125 minutes for 4 hours efective working time.

Judul: Studi Gerak dan Aplikasinya untuk Peningkatan Efektivitas dan Keselamatan Kerja Pemanenan Kelapa Sawit Secara Manual
Abstrak: Oil palm harvesting activities may cause manual occupational safety and health problems. Motion study using natural range of motion (ROM) is needed to repair the process of harvesting so the movement can be more efficient and the fatigue can be reduced. Manual harvesting activities by using conventional tools named ‘dodos’ and ‘egrek’ were studied in this research. The aims of this research is to know the movement pattern and the risks distribution of the work motions, determine the level of the motion risks of harvesting procedure to minimize the risk. The result of ROM analysis show that the ergonomic risk occur in all of the upper body, such as the neck, shoulder and forearm. It is revealed that ‘dodos’ more effective than ‘egrek’ for 3 m bunches’s height and be optimum for 1 m bunches’s height. The good practice models for ‘egrek’ revealed that the ideal position of harvester is 30-45o relative from the position of the bunch and the formula for the distance is 𝑑=0.5 ℎ−𝑡 + 0.3, where d is the distance between harvester’s position and the tree, h is bunches’s height and t is the harvester’s height.

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.
