Fishery potential utilization in the waters of Aceh Jaya was dependent on fishing technology and still limited.The type of fishing gears which used in Aceh Jaya were beach seine, line fishing, gillnet, and liftnet. Liftnet used by Patek fishermen was floating liftnet. Bagan was classified in light fishing. The type of lamps which used by fishermen was fluorescent and set on the surface, whereas the surface lamp was less effective for use. This research used underwater lamp. The aims of this research were to get underwater lamp construction and determine the LED effectiveness. Construction of underwater lamp designed an innovation, that was the dimmed, so that fish which have aggregated by the light would more focus to the liftnet. The research methods were descriptive, fishing gear construction design, experiment or experimental fishing. Underwater lamp lights could help Patek fishermen for fishing and  got maximum catches. Total catches by using fluorescent light were 2343 kg. Meanwhile, total catches with underwater lamp were 3779 kg. Fish species that were caught by lift net were anchovy, peperek, tembang, mackerel, selar, japuh, and layur for 10 trip, 5 trip in the dark and the bright moon. Seen that there were differences of catches amount and composition by using fluorescent lamps and underwater lamp. The results of research it was concluded effective underwater lamp as a tool in fisheries liftnet.

The Quran mentions the term treasure in some letters with various derevasion. The mention of the word treasure is accompanied by the procedure of acquisition or utilization. One of them is the prohibition of consuming treasure in a vanity way. As many as 36 times a word that means vanity is mentioned in the Quran, including An-Nisa: 29 and At-Taubah: 34. Using a thematic interpretation approach, explores some of the ethical messages contained in these two verses. Forbidden treasures managed by vile. Indications of vanity include the emergence of disillusionment with the parties and be classified as zalim. P

<p style="text-align: justify;">Considering the low achievement of Indonesian students in international studies (PISA), which measures Higher-Order Thinking Skill (HOTS) in solving the problem, improving the quality of mathematics learning in Indonesia is very important. The purpose of this research was conducted to explore the variations in students’ learning strategies and students’ Self–Regulated Learning (SRL) in solving mathematical HOT problems. The study employed a mixed-method, namely quantitative and qualitative methods were applied through five tests and seven interviews for over eight weeks. Two types of instruments were employed in this study, and they include tests and interviews. At the initial stage, we randomly selected 30 students from all those in grade 10 (Senior High School ), after which 12 were chosen purposively after the pre-test for an interview, having satisfied all complete group, middle group, and lower group. All of them were treated using metacognitive questions. Data analysis techniques used were percentage, data reduction, presentation, and conclusion. The quantitative results showed the students could generally use orientation, organization, and elaboration learning strategies as observed with 68.3%, 60%, and 56.7% for complete, middle, and lower groups. Moreover, the students were also observed to have conducted three cognitive processes in selecting the rules for solving the mathematical HOT problem, namely using models and drawing, written texts, and combining both. Furthermore, their final solution failures were affected by their misconceptions and errors in creating the mathematical model. The interview results on designing the learning procedures, monitoring the progress, and evaluating the outcomes, show that the students’ SRL level is good for complete (89.3%), middle (75%), and lower groups (60.7%).</p>

Umur pahat sangat berpengaruh terhadap suatu produk baik dari segi kualitas pemesinan maupun biaya produksi dari produk tersebut. Faktor-faktor yang mempengaruhi umur suatu pahat bisa disebabkan oleh jenis material benda kerja, pahat, kondisi pemotongan, cairan pendingin dan jenis proses pemesinan. Kondisi pemotongan sangat mempengaruhi umur pahat dan tingkat kekasaran permukaan benda kerja. Tingkat kecepatan keausan suatu pahat akan mempengaruhi batasan umur pahat yang berdampak terhadap ongkos suatu produksi karena apabila pahat cepat mengalami keausan, pahat tersebut akan sering diganti/diasah sehingga ongkos pemakaian pahat akan semakin tinggi. Tujuan penelitian ini untuk mengetahui pengaruh umur pahat terhadap biaya produksi pada proses drilling menggunakan benda kerja baja karbon S 40 C serta tingkat kekasaran permukaan materialnya. Dari hasil analisa yang dilakukan dengan memvariasikan beban yang diberikan pada lengan ayun mesin gurdi maka dapat dinyatakan bahwa beban yang diberikan pada lengan ayun mesin gurdi sangat berpengaruh terhadap umur pahat dan biaya proses pemesinan. Semakin besar nilai beban yang diberikan pada lengan ayun maka semakin pendek umur pahat, semakin kecil waktu pemesinannya. Dan semakin kecil nilai beban maka semakin panjang umur pahat, semakin besar waktu pemesinannya. Biaya produksi yang paling ekonomis adalah pada pahat yang diberikan beban 2,5 kg sedangkan biaya produksi yang paling tinggi adalah pada pahat yang diberikan beban 2 kg. Tingkat kekasaran permukaan benda kerja yang paling besar adalah pada produk dengan menggunakan pahat 3 (beban 3 kg) sedangkan tingkat kekasaran yang paling kecil (halus) adalah pada produk dengan menggunakan pahat 1 (beban 2 kg).

The purpose of this study was to determine the effect of zakat accounting on public accountability of BAZNAS and LAZ in South Sumatra Province with the methodology used was descriptive using a questionnaire. While the data analysis used is simple linear regression analysis. So from this study it can be seen that the accounting for zakat influences the accountability of BAZNAS and LAZ in South Sumatra Province by 73.9%, then based on the results of the study it is known that the tendency of zakat accounting carried out by zakat institutions in South Sumatra Province has unfavorable criteria of 3 institutions or 10%, 2 institutions are quite good criteria, 5 institutions with good criteria and with very good criteria are 66.6% or as many as 20 amil zakat institutions.
