Wind Power Generator for Small Scale Fish Processing Unit at Coastal Area in Aceh, Indonesia

This paper presents a wind power technology used to generate electricity forsmall scale fish processing unit. The units consist of ice machines, green house solar dryer, fish smoke house and utilities. A 10 kW wind turbine system were installed in 2010 at Lancang Paru village, Pidie Jaya. Total number of energy required for small scale fish processing unit are calculated. Initial test shown that wind power generator able to produce maximum power of 5 kW at 4 m/s wind speed. This wind turbine is enough to provide electricity for small scale fish processing uni

Kemampuan Komunikasi Matematis Siswa dalam Materi Sistem Persamaan Linear Dua Variabel di Kelas VIII SMP

This research aims to know the mathematical communication skills of students on the material system of linear equations in two variables in class VIII SMP Negeri 1 Pontianak. The methods used in this research is descriptive method with case study research. Subjects for this researches were 30 students. The result analysis of data show that the ability to communicate mathematical students on matter system of linear equations two variables in class VIII SMPN 1 Pontianak is quite good, seen from level ability, ability over is quite good, ability medium-sized appertain less well and ability under very less well. Mathematical communication ability in mathematics student aspects illustrate idea in the form of words and mathematical model appertain good enough. Viewed from the ability, ability over appertain good. capability of medium-sized appertain pretty well and less well under appertain ability

Remediasi Miskonsepsi Menggunakan Media Lectora Inspire pada Materi Teori Kinetik Gas Siswa Kelas XI Man 1 Pontianak

The one group pretest postest pre experimental design was conducted to remedy student\u27s misconception of the kinetic theory of efficent by implementing the lectora inspire program. A series of aims question of the modification Certainty of Response Index of three option multiple choice test was administered to prompt this misconception among grade students of the goverment religious secondary school at Pontianak city. Eleven student participated in this study. Result indicated that the lectora inspire can be used to reduce the number of students misconception (ES=2,67). It is suggested that the lectora inspire program can be used as an alternative remediation activity of the physics concepts

Analaysis of the Effect of Relative Humidity in the Eggs Incubator

This study aimed to verify the effect of relative humidity during incubation ofduck eggs in the incubator on the rate of decline in egg weight, hatching day old duck weight, length and hatching eggs energy difference duck. Duck eggs taken from the poultry business in Meunasah Krueng, water fence, Lambaro, Aceh Besar. Then each egg was placed in an incubator unit in the three experimental groups, namely low humidity (57/58% RH), intermediate humidity (67/68% RH) and high humidity (71/72% RH). Incubation process done manually with temperature 38 oC incubator. Eggs were coded X and O adjacent to facilitate marking a reversal in current twice a day. Primary data retrieval from the first day until the fifteenth day by weighing the eggs and using electronic scales. Changes in egg weight reduction on the fifteenth day following (10.666%), (3.853%) and (2.859%) for the treatment of low humidity, intermediate andhigh, then the day of hatching eggs weigh hatching day old duck also showed that the weight is also affected by incubation and humidity differences by ANOVA analysis it can be concluded that the changes in egg weight reduction greatly influence the hatching duck weight difference and the difference so long incubation energy hatching day old duckling have more energy at low humidity (57/58% RH)

Faktor Risiko Hygiene Perorangan Santri Terhadap Kejadian Penyakit Kulit Skabies Di Pesantren Al-baqiyatushshalihat Tanjung Jabung Barat Tahun 2017

Background: Scabies incident at boarding school Al-Baqiyatushshalihat Tanjung Jabung West in 2015-2016 there are 200 cases. The aim of this study is the relationship of individual hygiene students with the incidence of skin diseases of skabies in Pesantren Al-Baqiyatushshalihat Tanjung Jabung Barat Year 2017. Method: This research is a quantitative research with case control approach Data collection method is done by distributing questioner then analyzed by Univariat and Bivariat. The case population in this study is all santri who suffer from scabies in Al-Baqiyatushship Pesantren in 2017. The control population is santri who do not suffer from scabies in Al-Baqiyatushshalihat boarding school. Sampling method using total sampling method. Data were analyzed univariat and bivariate with chi-square test. Result: The results showed that there was a correlation between skin hygiene (p-value = 0,004; OR = 3,125; 95% CI = 1,943-6,542), hand hygiene and nail (p-value = 0,001; OR = 3,473; 95% CI = 1,669-7,225), genital hygiene (p-value = 0,002; OR = 3,762; 95% CI = 1,668-8,574), clothing hygiene (p-value = 0,000; OR = 4,062; 95% CI = 1,926-8,571), hygiene (p-value = 0.000; OR = 4,316; 95% CI = 2,045-9,108), cleanliness of bed and bed linen (p-value = 0,000; OR = 13,895; 95% CI = 5,721-33,747) with incidence of Scabies Skin Disease in Al-Baqiyatushshalihat Pesantren Tanjung Jabung Barat.

The Effect of Contextual Approach and Learning Motivation on Students Skills in Writing News Text

This study aims to find out: (1) differences in the increase in learning outcomes of news text writing skills between low and high motivated students taught with contextual and conventional learning; and (2) the effect of learning approaches and learning motivation on news text writing skills. This study was a quasi-experimental design with nonequivalent control group design. The population in this study were all students of class XII Islamic Senior High School 1Pekanbaru, with the total number of 331 students. Cluster sampling technique was used.Thirty students in each class XII MIA 1 was used as the experimental class and class XII MIA 3 as the control class. Based on the data analysis, the results revealed at the 95% level of confidence that: (1) Students’ news text writing skill taught using a contextual approach is significantly higher than the students taught using conventional approaches because when learning using a contextual approach students are seen to respond well (2) the increase in low motivated students news text writing skills was significantly higher than students who were taught using conventional approaches because with the contextual approach students can understand learning well (3) the increase in high motivated students news text writing skills was significantly higher than students who were taught using conventional approaches because with the contextual approach students can understand learning well because high motivated students were s more active when they were taught using contextual approach, and (4) there is an interaction between learning approaches and student motivation in influencing the writing skills of Year 12 students because motivation to learn can determine the success in student writing skills. Thus the contextual approach can be used as an appropriate learning approach to improve students’ writing ability.     Keywords: writing skills, motivation, writing news texts, contextual approache
