Abstrak: The objective of the research were to examine the workload for several age levels of workers, to observe the tools and equipments utilization effect to fatigue, and also to recommend an optimal work system that related with tools/equipment utilization and work scheduling through ergonomic approach of sweet potato processing. The subjects employed in this research were 12 employees that divided based on age level into young, middle, and old age. The results of this research showed that the highest energy consumption when doing a work is on subject in old age group. Therefore, the morning shift is preferable to be taken by the old age workers with assistance from young and middle age workers, whereas afternoon and night shift were preferable for middle and young age. The highest productivity was coming from the middle age group that was constant in every work shift. The questionnaire results indicated that the workload of subjects on medium workload category, but in case of working equipment, subjects were situated in very uncomfortable category for using working tools and equipment, so the repairments based on anthropometric dimensions are required in order to fit the workers to the task.

Judul: Workload analysis and optimization of harvesting procedure at sari lembah subur oil palm Plantation, Riau
Abstrak: Nowdays, oil palm harvesting process is still done manually which led to many variations in quality of harvest, workburden or physical disorder. This study aimed to determine the rate of energy consumption, workburden level and recovery time so that the best procedure of harvesting can be obtanined based on the productivity and labor’s capacity. This research was conducted with heart rate analysis approach, the standard time of harvest and work productivity. This study was conducted at 8 harvesters that have been observed as subjects that grouped by age, variations in topography and the use of harvesting equipment. The result showed that the rate of energy consumption for subjects aged < 30 years was higher than subject aged > 30 years. Based on the topography, harvesting which is done in terraced area required energy consumption rate more than flat area. Based on the using of tools, harvesting which is done using “egrek” have energy consumption rate higher than “dodos”. Working in pairs can be the best alternative for harvesting oil palm in F-B-D, T-K-E and F-KE. At F-B-D condition harvesting activities is done by 2 people aged > 30 years old. Then, at T-K-E and F-K-E, harvesting is conducted by 3 harvesters that consisted of 1 person aged > 30 years for doing the first subsystem and 2 people aged < 30 years for doing the second subsystem.

Judul: Peranan nyamuk sebagai vektor Dirofilaria immitis pada anjing
Abstrak: Dirofilaria immitis adalah cacing jantung yang hidup dalam ventrikel kanan dan arteri pulmonalis dari anjing; namun secara alamiah cacing ini dapat ditularkan kepada kucing, rubah dan karnivora yang lain. Cacing ini termasuk kelas Nematoda, famili Filariidae dan genus Dirofilaria, dengan bentuk tubuh langsing, berwarna putih dan daur hidupnya tidak langsung. Penyebarannya meliputi daerah beriklim sedang dan tropis seperti Timur Jauh, Pasifik, Afrika Utara dan Tengah, Australia serta Amerika Utara dan Selatan. Di Indonesia cacing ini jarang ditemukan. Nyamuk dari genus Anopheles, Culex, Aedes dan Mansonia merupakan vektor yang utama dari cacing jantung ini. Beberapa jenis pinjal seperti Ctenocephalides atau Pulex ternyata juga mampu menjadi vektor, meskipun kejadiannya jarang ditemukan. ...
