ABSTRAKThis research was conducted in September 2021 at the Bungus Ocean Fishing Port, West Sumatra Province. This study aims to determine the type of catch, analyze the technical and financial aspects of the fishing business and determine the feasibility of the fishing gear on the boat lift net. The method used in this research is the survey method. From the results of this study, the main catches (HTU) were squid, scad, mackerel, and anchovies while the by-catch (HTS) were skipjack and tuna. The financial analysis and profitability of the lift-net fishing business shows that the capture fisheries business with this tool is financially profitable and has a short payback period. The analysis of the feasibility of fishing business by fishermen for a full year is feasible to be developed, because the total revenue is greater than the total revenue is greater than the total cost and the value of Revenue Cost Ratio > 1. This can be interpreted that fishermen are classified as profitable. Keyword: Lift net, catch, financial analysis and feasibility

This research aims to develop an Augmented Reality-based learning media. This research is a type of development research. The development model used is the ADDIE model, which consists of five stages, namely, analysis, design, development, implementation, evaluation. The results of this study are in the form of cards that have been coded, Augmented Reality applications in Android, and student guide worksheets. The results of the validation of media and material experts indicate that this Augmented Reality-based learning media product is valid and feasible to use. The use of Augmented Reality based learning media in learning activities can improve students understanding of mathematical concept ability. This can be seen from the average n-gain obtained 0.61, which is included in the height category. Each indicator of the concept of understanding also shows big and medium improvement. This Augmented Reality based learning media also gets positive responses from students with an average percentage score of 87.50%.

Mathematical teaching aids are a set of concrete objects designed, created, collected, or arranged on purpose that is used to help instill or develop concepts or principles in mathematics—the purpose of this study to improve students' mathematical communication skills by using teaching aids. The method in this research is a quantitative approach. This type of research is experimental research, where the purpose of this study to examine the effect of teaching aids on students' mathematical communication skills. The study was conducted on 26 students randomly. Students are selected based on scores from the highest to the lowest on their mathematical abilities. The instruments used were the pretest and posttest of the set material in the form of students' mathematical communication skills. Based on the analysis results, set magnetic teaching aids in learning selected material shows a good category. This was obtained from the posttest average score of 86.73.

Permasalahan yang dihadapi panitia seleksi adalah bahwa wali kelas menunjuk siswanya secara acak. Siswa tersebut mendapat bantuan dari pemerintah berupa sejumlah uang tunai yang diberikan secara langsung kepada siswa sesuai kriteria yang telah ditetapkan. Kesulitan dalam menentukan siswa yang berhak mendapatkan bantuan yang sesuai capaian standar yang diinginkan. Penentuan siswa terbaik harus didukung oleh sistem seleksi untuk memilih siswa yang diterima terutama bagi Siswa Miskin. Pemecahan masalah dapat dilakukan dengan merancang Sistem Pendukung yang sederhana terhadap Keputusan Seleksi Calon Penerimaan Bantuan Siswa Miskin dengan menggunakan Metode Simple Additive Weighting di SMK NU Ma'arif 2 Kudus yang merupakan status sekolah swasta. Metode pemeringkatan ditentukan dari data identitas dari siswa berkualitas atau berbobot berdasarkan kriteria penilaian yang telah ditentukan. Kriteria yang digunakan dalam Sistem Seleksi berdasarkan Penghasilan Orang Tua, nilai Rapor Rata-rata, dan jumlah Keluarga. Jumlah siswa yang akan terseleksi sebanyak 10 siswa untuk mendapatkan bantuan beasiswa siswa miskin.The problem faced by the selection committee is that the homeroom teacher appoints their students randomly so that there is difficulty in determining who is entitled to receive assistance in order to achieve the desired standard and obtain the best candidates. To overcome this problem, a Decision Support System (SPK) was designed for the Selection of Candidates for Reception of Poor Student Assistance (BSM) using the Simple Additive Weighting (SAW) Method at SMK NU Ma'arif 2 Kudus, which is a simple ranking method by finding weighted summations based on predetermined assessment criteria. The criteria used in the Selection System for Prospective Assistance for Poor Student Assistance (BSM) using the Simple Additive Weighting (SAW) Method at SMK NU Ma'arif 2 Kudus, namely: Total Parents' Income, Average Score Report Card, Number of Relatives.
