Abstract

Kalimantan Barat dilalui Garis Khatulistiwa dimana surya menyinari selama 10-15 jam/hari. Energi surya diserap langsung oleh sistem pemanas surya. Energi panas yang dihasilkan dapat digunakan sebagai sumber panas dalam menghasilkan bahan bakar  terbarukan misalnya bioetanol dan biodiesel.  Implementasi untuk gagasan di atas dapat berupa teknologi pemanas surya yang sederhana, tanpa memerlukan energi listrik, biaya operasi murah dan ramah lingkungan.  Tujuan penelitian ini adalah merancang dan menguji pemanas air surya.  Pemanas surya dirancang bertipe datar dengan media pemanas berupa air. Pemanas surya terdiri dari kolektor panas dan tangki penampung air yang terbuat dari bahan stainlees steel dan polistiren sebagai isolator. Hasil rancang diperoleh pemanas air surya berkapasitas 50 liter yang diuji selama 3 hari dan mampu menghasilkan temperatur air maksimal sebesar 53oC pada intensitas cahaya rata-rata sebesar 1426 lux.

Abstract

This paper presents a robot concept which is the robot can play the instrumental Gamelan music. Gamelan is a percussive instrument. Instrumental Gamelan music keys are consist of 2 octaves in 15 tones. Robot Gamelan music is using proportional-derivative (PD) control system. PD control of the robot is by controlling DC gear motor position to desired Gamelan key position. Robot Gamelan music using ATmega 16 microcontroller as a controller. Feedback of PD control is using magnetic rotary encoder (MRE) sensor. PD control is using the constant. The constant functions of PD control are determining the pulse width modulation (PWM) toward DC gear motor velocity in order to reposition a gamelan key position and pushing down the errors.

Abstract

Basicly Musyarakah in fiqh muamalah is agreement of trust (amanah), which each of partners be rialiable with their own partner that have agreement with them, then in agreement of musyarakah each of partners do not allowed to ask for assurance to other partners. This research uses field research method by directly interviews the authorities of PT Bank Kalsel Syariah Banjarmasin Branch. The result of the procedure of musyarakah finance which is given by PT Bank Kalsel Syariah Banjarmasin Branch  is a coorperation agreement between the bank and the clients where each of partners gives the contribution of fund and work in undertaking productive business. The profit result divide based on nisbah that has been agreed and one of the partners can ask the more pofit based on their works and the loss devides proportionally based on the fund that had been deposited by each of partners. The client is asked to include the additional material wealth assurance that worth of the price as a serious prove and responsible reflection of the clients to undertake a coopertion and also as bank media in undertaking the principle of carefulness in giving the finance.

Abstract

AbstractThe title of this research is "Application of Think Pair Share Learning Models to Improve Learning Outcomes of PPKn Students in Class VII Semester I MTS Hidayatus Sibyan 2017/2018 Academic Year. The purpose of this class action research was. 1) Applying the think pair share learning model to improve the learning outcomes of students. 2) Increasing the absorptive capacity of students in the PPKn learning eye for MTS Hidayatus Sibyan VII class with the implementation of the think pair share model.3) improving student learning outcomes in the learning eyes of class VII PPKn MTS Hidayatus Sibyan. This Classroom Action Research was conducted on students of Class VII Semester I MTS Hidayatussibyan 2017/2018 school year. the level of success of the pree test of students who reached 78 was 15 students and those who scored 78 as many as 14 students with a mean grade of 71, 44 and the percentage of completeness was 51.72%, this means that some students have not been able to master the preparation material. In the first cycle, students who achieved a score of 78 were 16 and those who scored 78 were 13 students with a mean grade of 71.96% and the percentage of learning success was 55.17%. Whereas in the second cycle students who scored ? 78 were 26 students and those who scored ? 78 were 3 students with a class average value of 83.96 and the percentage of learning success was 89, 65%. Based on the results of the second cycle test, there was an increase in student learning outcomes.Keywords: Think Pair Share learning model, To Improve Learning Outcomes

Abstract

This paper presents solution trajectories for programmed PWM technique to eliminate specific order harmonics in a single phase inverter. Evolutionary algorithm is applied to determine optimum switching angles in order to elmininate low order harmonics for modulation index: -1 £ M £ +1. An implementation using a DE2-115 Cyclone IVE FPGA device is also reported in this paper. The experimental results show that the technique effectively eliminates the specific harmonics, and offers low harmonic distortions on the inverter output after filtering.

Abstract

The main problem in this research are: 1) What are the variables Green marketing (Price, Place, Promotion, Product) influence the decision variables travelers. 2). Between four Variable in Green marketing Which one that the most influential variable against the decision variables travelers. The aim of this study is: To test the effect of Green Marketing Strategy to decision travelers. For the purposes of applying the method of descriptive, descriptive statistical methods with the help of a computerized system (Computer Program SPSS version 16) by using a formula that is multiple regression analysis, t test and F test, Based on the analysis of the Effect of variables Green marketing (Price, Promotion,), it would seem that there is no significant effect between price and promotion by the decision of rating this menunujukkan that the tourist destinations of Batu city has its own appeal against the rating even though the goods and services offered relatively expensive, as well as the absence of cuts at a time when the holiday season is not a constraint travelers choose travel destinations New city as a place traveled. Thus it can be said unproven hypothesis. And the effect of variable Green marketing (Place and Product) with a rating decision, is known to have a significant influence with the decision of travelers choosing travel destinations Batu city as a place traveled. Thus it can be said to be proven hypothesis. Variables that most large / dominant influence rating decisions Place (place), the reason for the variable Place (place) had the biggest regression coefficient.
