Abstract

Aktivitas praktikum lapangan merupakan kegiatan yang dilakukan sebagaiimplementasi kurikulum akademik di Jurusan Fisika FMIPA UNIMA. Sebagaiimplementasi kurikulum tersebut telah dibuat model aktivitas praktikum lapangan (modelAPeL) dan telah digunakan sejak tahun 2001. Namun model APeL ternyata menimbulkanrisiko yang merugikan bagi mahasiswa dilihat dari respon fisiologis dan kelelahansehingga mahasiswa belum dapat mencapai kinerja yang diharapkan. Untuk itu telahdiupayakan dengan penerapan pendekatan ergonomi total (PET) suatu model baru yaitumodel APeLErg. Untuk menguji keandalan model APeLErg dibandingkan dengan modelAPeL, telah dilakukan penelitian dengan hipotesis: model APeLErg, dibandingkan denganmodel APeL; memperbaiki respon fisiologis tubuh; menurunkan kelelahan; danmeningkatkan kinerja mahasiswa di daerah dataran rendah/panas dan di daerah datarantinggi/dingin. Penelitian ini dilakukan dalam dua tahap dengan menggunakan rancangansama subjek. Penelitian pada tahap pertama dilakukan di daerah panas denganmenggunakan 15 orang subjek sedangkan penelitian tahap kedua di daerah dinginmenggunakan 18 orang subjek. Hasil penelitian tahap I dan tahap II menunjukkan bahwaaktivitas dengan model APeLErg dapat: memperbaiki respon fisiologis mahasiswa secarasignifikan (p<0,05); menurunkan rata-rata skor kelelahan umum secara signifikan(p<0,05); meningkatkan kecepatan, kekonstanan dan ketelitian mahasiswa secarasignifikan (p<0,05); dan meningkatkan kinerja mahasiswa secara signifikan (p<0,05). Darihasil penelitian ini dapat disimpulkan bahwa model APeLErg dapat: memperbaiki responfisiologis mahasiswa; menurunkan tingkat kelelahan mahasiswa; dan meningkatkankinerja mahasiswa dalam melakukan aktivitas praktikum lapangan.

Abstract

n the Environmental Physics concentration, to implement the academic curriculum of Physics Department of FMIPA UNIMA, it had been made guidance in the book form to be used in performing the field practicum activity. The guidance had been utilized since the year 2001. However, the conventional activity apparently caused unfavorable risks to the students based on the efficiency of circulatory system so that the students could not attain the intended performance yet. Therefore, it has been arranged a new model of activity with several treatments by using the totally ergonomics approach. In order to test the capability of the activity compared with the conventional one, it had been done a research with the hypothesis: the intervention with the totally ergonomics approach decreases and the body core temperature of the student in the low land/hot area. This research was done by using the design of treatment by subject. The research has used 15 subjects as sample. The measurements of dependent variable were done in the beginning, among units of practicum, and the last on the end of period. The results of the research showed that the activity with the totally ergonomic approach could decrease fatigue and the body core temperature of the student significantly (p<0.05). With the decreasing of fatigue and body core temperature, it means that the activity is good biomechanically and thermally (in low land/hot area). The fatique and hyperthermia condition were responsible as the main cause of the low performance of the students. The activity with ergonomic intervention by using the totally ergonpomics approach succeeds in overcoming the fatigue and hyperthermia condition so that the performance of the students could increase considerably. Based on the research it can be concluded that the intervention with the totally ergonomic approach can: decrease fatigue and decrease body core temperature of the students in doing the field practicum activity. It can be suggested that in doing the activity with ergonomic intervention by using the totally ergonomic approach, principal requisites of every treatment must be fulfilled in order to achieve the intended goals.

Abstract

In the physics learning process, one of the things to look out for is developing a change in the student's concept that extends the concept from incomplete concepts to complete and perfect. These concepts often deviate from the correct concept. Misconception are initial concepts that are inconsistent with the scientific concepts agreed by experts. This departure from the concept is known as a misunderstanding. This study aims to determine the extent of student misunderstandings in physics material at SMA Negeri 8 East Halmahera using the Certainty Of Response Index. The subjects used in this study were 30 students from Class XII MIA at SMA Negeri 8 East Halmahera. Retrieving data in this study in the form of a multiple choice diagnostic test (reasoned multiple choice test) 50 numbers, accompanied by the CRI (Certainty of Response Index) of the students on Effort and energy 15 items, Temperature and Heat 17 items and 18 static electricity. The data were analyzed qualitatively. From the results of the data analysis, the following conclusion emerged: The degree of misconception of material temperature and heat was 47%. This was the ultimate misconception of the three materials. This proves that most of the students do not understand the material temperature and heat compared to the material from Effort and energy with a misunderstanding rate was 13%, and the static electricity where a misunderstanding occurred was 20%. Overall, the misunderstanding among students is still low at 35%.

Abstract

Geothermal is now widely used by several developed countries, there are very many roles of geothermal energy sources, it is necessary to use one of them by utilizing geothermal heat energy itself into electrical energy. In chemical process industry there are a number of processes where a gas and a liquid come into contact with each other and whenever this happens, the gas will introduce a number of liquid particles. This liquid phase carried over to the gas phase can cause a number of problems such as equipment breakdown, process inefficiency etc, and need to be eliminated. Equipment used to remove entrainment is known as a Demister. This study aims to calculate Demister Efficiency throughout 2019 at PLTP Lahendong. Research conducted is to collect data at the Lahendong Geothermal Power Plant Unit-2 and this research uses data processing methods that use applications, namely steam tables and Microsoft Excel. Demister's performance in 2019 for 3 months got 88.90% J results which were influenced by heat loss, pressure and inner diameter, from results obtained after processing it can be concluded that the higher the heat loss value, better the efficiency value, Explains that performance Demister arguably had no problems in a year.

Abstract

Temperature and air pressure are two elements of meteorology that are interrelated because air pressure together with temperature will determine the air density and will then determine the lift of an airplane. One of the disturbances that affect flight operations (lift) is temperature and air pressure. Research has been carried out, namely to determine the effect of air pressure and air temperature on flight operations (lift). Pearson Product Moment Correlation Analysis Method is a method used to determine how much the value of the relationship between temperature and air pressure on flight operations (lift) .From the results of research at Sam Ratulangi airport in Manado, it shows that the relationship between temperature and air pressure is very strong on flight operations in particular (Lift) on the airplane. By using data on F - Klim 71 in 2010 - 2019 the strongest relationship occurred in November and December with the determining coefficient values ​​of 97.29% and 99.91. Air pressure and air temperature together have a strong influence on flight operations specifically "lift". Meanwhile, air temperature tends to have a stronger influence on flight operations (lift) than air pressure.

Abstract

The development of technology, population and inovation from day to day is increasing. This causes the world's energy needs to increase as well. This causes both developed and developing countries including Indonesia to take advantage of every alternative available energy resource, both renewable energy and non-renewable energy. One of the uses of renewable energy for national energy sufficiency is geothermal resources, Indonesia's strategic location causes Indonesia to have a lot of potential geothermal resources and because of that these geothermal resources must be processed as efficiently as possible to help meet national energy needs. One of the causes of the reduction in the efficiency of processing geothermal resources is the pressure drop that occurs from the demister to the turbine, this study aims to determine the pressure drop that occurs from the demister to the turbine at PLTP-2 Lahendong using 3 methods, namely Lockhart Martinelli, Homogenous and Harrison Freeston. . The results of the calculation of these 3 methods are then compared with real data in the field to find out which method is the most aaccurate and closest to use. Based on research, the turbine inlet pressure from the Homogenous method, Lockhart Martinelli and Harisson Freeston are 6.59bar, 7.25bar and 7.84 bar respectively and the level of accuracy compared to real data is 92%, 97% and 90%, respectively.

Abstract

Geothermal is a natural heat resource that comes from the interaction between hot rock and water. The results of these interactions are trapped in a place called a geothermal reservoir. North Sulawesi is an area that has geothermal potential, one of which is in Bakan, Bolaang Mongondow, geothermal potential here is a manifestation of hot springs. The purpose of this study was to determine the characteristics of geothermal fluids in the Bakan Village area, using the Cl-Li-B geoindicator method. The use of the Cl-Li-B geoindicator results in Cl being more dominant than Li and B indicating that hot water coming from a heat source that rises to the surface is a fluid originating from a heat source with little cooling, a low B/Li ratio indicates that the fluid zoning is in the upflow zone.
