ABSTRAKLimbah tempurung kelapa sawit merupakan limbah padat yang dihasilkan dari pengolahan kelapa sawit. Untuk meningkatkan nilai tambah, maka limbah ini dapat dimanfaatkan menjadi briket arang yang dapat digunakan sebagai salah satu sumber energi alternatif. Tujuan penelitian adalah untuk mendapatkan briket arang tempurung kelapa sawit yang secara teknis dapat memenuhi persyaratan kualitas bahan bakar. Perlakuan yang digunakan yaitu suhupengarangan (400 C, 500 C dan 600 C) dan waktu pengarangan (2 jam, 3 jam, dan 4 jam). Arang serbuk dicampur dengan perekat amylum 5% dan dicetak berbentuk silinder dengan diameter 3 cm dan tinggi 7 cm. Briket yang dihasilkan dianalisis mutunya yang meliputi kadar air, kadar abu, kadar karbon, kadar zat terbang, kadar sulfur, nilai kalor, kerapatan dan kekuatan tekan. Berdasarkan hasil analisis dan pengolahan data diperoleh bahwa suhu dan waktu pengarangan berpengaruh sangat nyata terhadap kualitas briket arang.

This research aimed to identify the effect of POGIL model on the students’ mathematical problem-solving ability. The variables involved in this research were mathematical problem-solving abilities as an independent variable, and the POGIL model as a dependent variable. Based on the observations of researchers through interviews with mathematics subject teachers and students at Junior High School 2 Kalibagor, showed that the mathematical learning process that took place was still dominated by learning that did not involve the active role of students. The learning used is still teacher-centered and limited to information transfer, especially in the form of theoretical and mathematical equations. The population of this study was the students at seventh grade in Junior High School 2 Kalibagor, even semester in the school year 2017/2018 consist of 8 classes and amounted to 219 students. Sampling was done randomly, selected as an experimental class is 66.91 with 30 students and 55.91 as control class with 30 students. This test was validated by two mathematicians, then it was tested to a group of seventh-grade students to fulfill the validity and reliability criteria. The data were analyzed by using t-test after conducting a series of normality and homogeneity tests. It was concluded that t-test for equality of means was used for hypothesis testing that shows a significant value = 0.000 less than alpha 0.05. So that H0 is rejected, it means that students’ mathematical problem-solving ability taught by using POGIL model is better than students’ mathematical problem-solving ability taught by conventional learning. In other words, POGIL model influences or effects on students’ mathematical problem-solving abilities.

Social and economic inequalities have sharpened in the late 20 th century. During this period, Europe has witnessed a rising unemployment rate, a declining wages for the least qualified workers, a slowing of income growth, and an increasing gap between the richest and the poorest. Based on the hypothesis of the relation between socio-economic condition and mobility behaviour, it is necessary to ask how these socio-economic inequalities manifest themselves in transportation: does a rise in income inequality lead to a rise in transportation inequality and mobility practice inequality? This question is particularly relevant today as some European countries are facing high socio-economic inequalities following the financial crisis that started in 2008. Using results from transport, car ownership and mobility surveys as well as household surveys from the Paris (Île-de-France) region between eighties and late nineties, this paper tries to answer this question. The results show how inequalities in transportation and mobility practice have decreased during the period in spite of an increase in income inequalities. We find that the evolution of socio-economic inequality, most specifically income inequality was simply one of the determining factors of the evolution of inequalities in transportation and mobility practice. In fact, the most important role in that evolution is not played by the evolution of income inequality but by the evolution of elasticity between transportation and income. Reducing the effects of this elasticity should be the main target of transport policies to diminish inequality in transportation and mobility practice.

<p class="BodyCxSpFirst">Pemanfaatan teknologi informasi sangat penting bagi rumah sakit, karena berpengaruh pula terhadap kualitas pelayanan kesehatan yang secara manual diubah menjadi digital dengan menggunakan teknologi informasi.Dalam penelitian ini penulis menggunakan metodologi <em>Nine step</em> sebagai acuan dalam merancang suatu <em>data warehouse</em><em>,</em> untuk pemodelan menggunakan skema konstelasi fakta dengan 3 tabel fakta dan 11 tabel dimensi. Perbedaan penelitian ini dengan penelitian sebelumnya terletak pada sumber data yang diekstrak langsung dari <em>database</em> SIMRS yang digunakan rumah sakit, sehingga tidak ada ekstraksi data secara manual.Penelitian ini bertujuan untuk menghasilkan desain data warehouse berbasis Online Analytical Processing (OLAP) sebagai sarana penunjang kualitas pelayanan kesehatan rumah sakit.

This study aims to describe (1) compliance with the language politeness principle, (2) violation of the language politeness principle in the talk show segment in the NET Morning TV Show Indonesia and (3) its relevance to learning Indonesian in class X SMA. In this research, the data collection uses competent and free listening techniques and note taking techniques and the data presentation techniques use informal techniques. Based on the results of data analysis, the 76 principles of politeness maxim that were found in this study consisted of 14 maxims of wisdom maxims, 14 maxims of generosity, 19 maxims of praise, 6 of maxims of humility, 19 of maxims of agreement, and 4 of maxims of sympathy . The violations of the language politeness principle found in this study amounted to 25 consisting of 2 violations of wisdom maxim, 3 violations of generosity maxim, 2 violations of praise maxim, 5 violations of humility maxim, 11 violations of agreement maxims, and 2 violations of sympathy maxim. The results of the analysis in the study are relevant to Indonesian language learning in class X SMA, as stated in the basic competency syllabus (KD) 4.3, which is developing the contents of the exposition text (problems, arguments, knowledge, and recommendations) verbally and on basic competencies (KD) 4.10 namely submitting submission, offer, approval and concluding in the negotiating text verbally.
