Abstract

Proses peleburan timah menghasilkan limbah berupa slag II dalam jumlah besar. Slag II sebagai terak pada proses peleburan timah masih mengandung beberapa unsur utama antara lain 0,0619% uranium, 0,530% thorium, 0,179% P2O5, dan 6,194% logam tanah jarang (LTJ) oksida total. Berdasarkan fakta tersebut, maka sangat menarik untuk meneliti pengolahan slag II, terutama untuk memisahkan uranium dan thorium yang terkandung di dalamnya. Uranium dan thorium dilarutkan dengan pelarut asam (H2SO4). Recovery pelarutan slag II dari hasil peleburan timah pada kondisi optimum adalah 98,52% uranium, 83,16% thorium, 97,22% fosfat, dan 69,62% LTJ. Uranium, thorium, LTJ, dan fosfat yang telah terlarut diendapkan agar masing-masing unsur terpisah. Faktor yang mempengaruhi kesempurnaan reaksi pada pengendapan antara lain reagen yang digunakan, pH reaksi, suhu, dan waktu. NH4OH digunakan sebagai reagen pengendapan dengan kondisi optimum proses pada pH 4. Suhu dan waktu reaksi tidak mempengaruhi proses. Recovery pengendapan yang dihasilkan adalah 93,84% uranium dan 84,33% thorium. Kata kunci: pengendapan, uranium, thorium, slag II, recovery

Abstract

The purpose of this study was to determine the use of demonstration methods in fiqh learning, to determine the obstacles faced in the use of demonstration methods in students, to find out the solutions applied in overcoming obstacles that occur in demonstration methods and to find out student learning outcomes in jurisprudence learning at MI PUI Jatisawit. While the solutions implemented to overcome these obstacles include: Making regulations that require students to carry out divine commands, motivate students and provide guidance in carrying out Fiqh learning, complete infrastructure as support for KBM, provide evaluation and oversee student activities during at school, and increase the hours of religious studies that initially only two hours to three hours. Moreover, for student learning outcomes in jurisprudence, lessons can be categorized as useful, which is first calculated using the percentage scale calculation.

Abstract

This research aims to analyze the influence of servant leadership and communication competence on the facilitators performance of PKH in north Aceh with job satisfaction as the intervening variables. Sampling using the census method with total sample of 150 PKH facilitators in North Aceh. The tool analysis used is Structural Equation Modeling (SEM) with using AMOS. The results of this research show that servant leadership positively influences, but not significantly on job satisfaction and performance. Communication competence significantly and positively influences on satisfaction and performance. Job satisfaction significantly and positively influences on performance. Job satisfaction does not mediate the relationship servant leadership toward performance. Job satisfaction partially mediates the influence of communication competence toward performance.

Abstract

This research aims to design integrated poster media with Al-Qur'an verses on solar system material and to determine the feasibility of integrated poster media with Al-Qur'an verses on solar system material. This research uses Research and Development (R&D) research with a 4D model developed by Thiagarajan. The 4D model has several stages consisting of the definition stage, the design stage, the development stage, and the final stage, namely the disseminate stage. The instrument used in this research was an expert validation sheet consisting of three experts, namely learning material experts, learning media experts, and Al-Qur'an interpretation experts. The product resulting from this research is an integrated poster media with verses from the Koran on the solar system. The results of material expert validation with the content feasibility aspect were 92.5%, the presentation feasibility aspect was 96.87% and the linguistic component aspect was 90.33%, with the average total of all scores obtaining a percentage result of 93.33%. Media expert validation with design feasibility aspects of 100%, content and objective quality aspects of 88.75%, instructional quality aspects of 93.75%, and technical aspects of 100%, with an average total of all scores resulting in a percentage of 95.62%.

Abstract

Penelitian ini bertujuan untuk mengetahui efektivitas penggunaan murattal Al-Qur’an sebagai backsound (pengiring) dalam meningkatkan konsentrasi belajar Fisika siswa. Adapun subjek dalam penelitian ini yaitu siswa kelas X MIPA 6 di SMA Negeri 3 Banda Aceh. Instrumen yang digunakan pada penelitian ini berupa audio, angket Pre Test dan Post Test konsentrasi siswa, serta wawancara terhadap 5 orang siswa dari kelas yang diteliti. Penelitian ini menerapkan media audio murattal Al Qur’an agar membuat kondisi kelas menjadi kondusif sehingga siswa dapat berkonsentrasi pada saat belajar Fisika. Murattal Al-Qur’an efektif dan berpengaruh positif terhadap aspek menjawab, psikologi, dan lingkungan. Namun murattal Al-Qur’an tidak efektif terhadap aspek sambutan lisan (verbal respons). Penelitian ini juga menemukan bahwa terdapat pengaruh “negatif” penggunaan murattal Al-Qur’an dalam pembelajaran fisika terhadap aspek fokus pandangan, perhatian, dan sambutan psikomotorik.

Abstract

This research is motivated by the use of learning methods that are still monotonous and uninteresting, the discussion of one of the physics materials that is difficult for students to understand, namely static fluid materials. This results in students having difficulty understanding the concepts and equations contained in static fluid materials. To overcome this problem, an interactive physics learning video based on the Science Environment Technology Society (SETS) was developed in order to provide students with an understanding of static fluid materials and become a digital media that can be used in the long term because it is flexible so that it can be used anywhere to repeat static fluid materials. The objectives of this research are: (1) To design interactive physics learning videos based on SETS at the high school/MA level; (2) To find out the feasibility of interactive physics learning videos based on SETS at the high school/MA level and (3) To find out the practicality of interactive physics learning videos based on SETS at the high school/MA level. This study uses the Research and Development (R&D) method based on the Alessi and Trollip development model. In this study, a product was produced in the form of interactive physics learning videos based on SETS. The results of the study show that SETS-based interactive physics learning videos have met the category of very feasible. This is determined based on the results of validation from media experts with a percentage of 90.4% included in the "very feasible" criteria and the validation results from material experts obtained a percentage of 91.2% with the "very feasible" criteria and user validation results with a percentage of 93.2% with the "very feasible" criteria. The results of the practicality assessment by students received a percentage of 95% with the category "very practical" used in the learning process. Thus, it can be concluded that SETS-based learning videos can be used in the learning process.
