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: Autopoietic concept on ergonomics of worksystem (case study : sugar cane industry)
Abstrak: Sugar factory is one of industry that involves multiple parties as stakeholders. The design of work system should consider all interests, to ensure the sustainability of the system itself. Optimum conditions can be achieved by designing work system based on ergonomic considerations. In the concept of ergonomic, human beings are positioned as the center of the design process. Humans have the capacity and limitations and should be considered since the beginning of the design process. This concept is known as fit the job to the man. In preliminary studies, found several phenomena that deviate from this concept. In many ways, people can improve their skills so they can adapt to the workload and working environment. This study combines deductive and inductive methods, combined with some relevant philosophical outlook. Field research was conducted in two industries namely PG Jatitujuh Cirebon and PG Bungamayang Lampung. This study focused on the work of manual harvesting systems, transportation and milling sugarcane. The results showed that some parameters are less ergonomic working conditions, workload values are categorized between moderate to very severe, the contradiction between workload and perception of the operator and the phenomenon of adaptation of workers to harvest and transport worksytem manual. The workload of worker cutting transport was measured based on increase of the ratio of heart rate (IRHR), which compares the heart rate at work and at restRegression curve of IRHR vs experiences on morning harvesting follow the function Y= -0.105 ln(X) + 1.7484; for morning transporting Y= -0.046ln (X) + 1.7323 ; for afternoon harvesting Y= -0.063 ln(X) +1.5482, and for afternoon transporting Y= -0.044 ln(X) + 1.595. Differences of the slope of the regression curve shows that the level of adaptation required by the workers on the harvesting longer than transporting. This is due to cut sugar cane requires greater physical energy and skill. Novice workers learn to be able to cut the cane with a limit of 50-10 cm above the ground, in an upright cane conditions, collapsed or angled, even crossing each other. The results indicate that with increasing experience, response to fatigue and workload tends to decrease. This process can be explained by the concept of autopoeitic, which is each component in a system will make the process of self-organizing. This adaptation process is one of the autopoeitic mechanism. To adapt to the harvesting and transporting jobs, workers may take between 6-10 years experience.

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. ...
