Pengaruh Advance Organizer Berbasis Proyek Terhadap Kemampuan Analisis – Sintesis Siswa

Penelitian ini dilakukan untuk mengetahui pengaruh model pengatur kemajuan (advance organizer) berbasis proyek terhadap kemampuan analisis – sintesis siswa pada konsep Energi. Sebelum pembelajaran, diberikan tugas proyek pada siswa untuk merealisasikan bel listrik sederhana, rangkaian arus seri - paralel, dan tuas. Produk proyek digunakan sebagai advance organizer dalam pembelajaran di kelas. Penguatan kognitif dilakukan melalui diskusi kelompok dan pembuatan peta konsep, ekspositori guru di kelas, dan kegiatan eksperimen laboratorium. Data diambil melalui pretest, post test, observasi partisipatif pembelajaran oleh dua orang observer, penilaian produk, peta konsep dan laporan kegiatan eksperimen. Teknik analisis data meliputi uji prasyarat data dan uji hipotesis Hasil penelitian menunjukkan bahwa siswa mengalami peningkatan kemampuan analisis – sintesis dalam aspek menguraikan, mengkategorikan, mengidentifikasi, merumuskan pernyataan, merekonstruksi, menentukan konsep, dan menganalisis konsep dengan rata – rata peningkatan delta skor sebesar 54,46 %, uji t sebesar 6,4, dan skala gain sebesar 0,3. This study was conducted to determine the effect of project-based advance organizer model on student's analysis - synthesis ability of the energy concept. Students were given an assignment to realize the project on simple electric bell, the series – parallel circuit, and lever, before learning. The products of project were used as an advanced organizer in the learning activity. Cognitive strengthening was done through group discussions and concept mapping, expository learning in the classroom, and laboratory experiments activities. The data were taken through a pretest, post-test, participant observation study by two observers, product assessment, concept maps and report of experiment activities. Results showed that the students' analysis - synthesis ability increased in the aspect of describing, categorizing, identifying, statement formulating, reconstructing, concept determining, and analyzing the concept. The average increase in delta score was 54.46 %, while the t-test score was of 6.4 and a gain scale of 0.3

Pengaruh Harga Bensin Terhadap Kecelakaan Lalu Lintas Di Indonesia

The Impact of Gasoline Price on Trac Accident in IndonesiaTraffic accident ranks the ninth largest of the cause of death in Indonesia. The most of researches studying Indonesia on traffic accidents were only blaming on human, motor vehicles, and environment as main culprits, not incorporating economic factors into the models. This study aims to analyze the impact of real gasoline prices on trac accident in Indonesia and the factors of influence them. This research employs time series data from 1970 to 2013 with OLS analysis world crude oil prices as instrument variable. The estimator results show that real price of gasoline and the policy of USAge of motorcycle light insignificant on traffic accident. Meanwhile, real GDP and asphalt roads significantly decrease the traffic accident. However, motorcycles significantly increase the traffic accident

Income Upgrading Model of Cattlemen in the Utilization of Artificial Insemination Technology: A Case Study in Village of Kanonang III, Regency of Minahasa

Cattlemen allocate labor on their cattle business. These activities have contributed further to the family income used to meet household needs. Besides the beef business, they seek food crops such as rice, corn, peanuts and so forth to obtain additional income. The breeders utilize the technology of artificial insemination and natural mating in the beef cattle production. The usage of insemination technology is expected to increase the income derived from the beef cattle that will result in increasing the investments and the income of farming food crops. The objectives of this study are to analyze the correlating factors that affect the farmers’ income from the cattle business and farming crops under condition of the usage of  artificial insemination technology and  to analyze the effects of the external factor changing  toward the profits of  beef cattle business, the costs of cattle production , the cost of crop production,  food crops farm income, animal health costs and the cost of the barn with the condition of the artificial technology usage. The measurement technology of the artificial insemination uses the cost inseminator approach. This research is a case study of 100  cattlemen in the village of Kanonang III Minahasa District selected by random sampling. Model of simultaneous equations with the method of 2 SLS is used to estimate all the parameters of the study. The result of research showed that the economic model of breeders can explain in relation to the use of artificial insemination with income and costs of production in cattle  and farm crops well. Insemination technology increases the profits for the  cattle production, the costs of cattle production,  the costs of crop production, farm food crops income, animal health costs and the cost of the barn. These results indicate that the artificial insemination technology can improve economics the performance of beef breeders.Animal Production 15(2):144-152, May 201

THE INTERFERENCE MANIFESTATION THROUGH INTERLANGUAGE : A STUDY ON A MULTILINGUAL CHILD'S VERBAL PERFORMANCES

Interference is often seen as an intrusion from the native language when a language learner is trying to perform the target language. In fact, it is more a part of the process of acquiring the target language which naturally happens before a language learner sucessfully achieves the target language proficiency. As a process rather than afinal product of learning language, it is hoped that it is not seen as a permanent incorrectness. The interference is manifested as an interlanguage. The interlanguage itself can be divided into 4 categories. namely overgeneralization, simplification, hypercorrection and avoidation. This research is trying to see the interference manisfestation of a multilingual child

Glomerulus Filtration Rate (GFR) Estimation Value Using Cockcroft and Gault Equation Against Community Exposure to Mercury at Artisanal and Small Scale Gold Mining (ASGM) Area in Lebaksitu Village, District of Lebak, Banten

The usage of mercury in Artisanal and Small Scale Gold Mining (ASGM) is quite troublesome because, within the process, ASGM produces mercury within its waste to the environment that might become pollution. Exposure of mercury to the body in long period could threaten the body’s health such as kidney as excretion organ thatexerts toxic materials from the body. Glomerulus filtration rate (GFR) is one parameter to evaluate the work of the kidney and the stadium of the kidney disease. This research aimed to understand the relation between mercury level in hair and GFR and used cross-sectional design with measured variables including mercury level in hair, respondent characteristic, and GFR. The respondents included 58 people. The output showed that 51.7% of respondents had mercury level above the guideline (> 2 ppm) in their hair and 43.1% of respondents had experienced a decrease in GFR (abnormality in kidney function). The decrease in GFR was caused by age and mercury level in hair. This decrease can be prevented by consuming more water, reducing medicine consumption, and conducting promotion about health service and the impact of mercury on public health. Keywords: glomerulus filtration rate (GFR), mercury level in hair, Artisanal and SmallScale Gold Mining (ASGM
