A teacher’s role involves creating an environment that stimulates and fosters critical thinking skills. One effective approach to promoting vocational values is through integrating mathematics geometry lessons with STEAM-based methods by developing learning modules that serve as independent teaching materials accessible to students. This research aims to design and develop a mathematics geometry learning module for fifth-grade students to instill vocational values. The study follows a Research and Development (R&D) methodology, employing the ADDIE development model. Data collection methods include interviews and questionnaires, analyzed through qualitative and quantitative techniques.The findings demonstrate that the quality of the developed learning module, as validated by five experts; two media specialists from BBPPMPV BOE East Java and three mathematics teachers from Al-YA’LU Excellent Elementary School in Malang meets high standards. Media experts rated the module’s design feasibility with an average score of 3.46, categorized as “highly feasible.” Subject matter experts evaluated the module’s content feasibility with an average score of 3.91 (“highly feasible”), linguistic feasibility at 3.93 (“highly feasible”), and contextual feasibility at 4 (“perfect”).

The conventional approach of current learning media and the limited utilization of Android technology among students as a learning medium highlight the need for improvements and updates in how information is delivered from teachers to students. Transitioning from traditional methods to more modern approaches, particularly by leveraging existing technology, is essential. This study aims to develop Android-based interactive multimedia using the Problem-Based Learning (PBL) model to enhance learning achievements in the maintenance of ABS (Antilock Braking System) brake systems. It evaluates the feasibility and the improvement in learning outcomes among students in the Light Vehicle Engineering Department at SMK Muhammadiyah 2 Semarang in cognitive, affective, and psychomotor domains. The research employs the ADDIE development model, which includes Analysis, Design, Development, Implementation, and Evaluation. The experimental design used is a Pretest-Posttest Control Group Design. The subjects consist of 60 eleventh-grade students from the Light Vehicle Engineering Department, divided into control and experimental groups. The results of the feasibility assessment by media and material experts are 83.20% (“Feasible”) and 88.78% (“Highly Feasible”), respectively. Improvements in learning outcomes are reflected in the N-Gain test results, with the experimental group achieving an average score of 0.4619, categorized as “Moderate,” while the control group achieved an average score of 0.2588, categorized as “Low.” Based on the N-Gain calculations, it can be concluded that the use of Android-based multimedia through the Problem-Based Learning model in ABS brake system maintenance materials is “Effective”.

Banking is a service industry that is very important in advancing the economy of a country. The purpose of this study is to determine whether there is an effect of variable customer value, satisfaction and relational marketing on customer loyalty Priority Bank XYZ Main Branch Office Surabaya Cendana. The data used in this study is primary data obtained by distributing questionnaires, using multiple linear regression analysis techniques. There is an influence between the independent variable and the dependent variable, as evidenced by a significant value of 6,328.10-26 <0.05. Partially, the customer value variable (X1) has a positive and significant effect on customer loyalty, the customer satisfaction variable (X2) has a positive and significant effect on customer loyalty and the relationship marketing variable (X3) has a positive and significant effect on customer loyalty. The most dominant variable is the relational marketing variable (X3) because the partial correlation value in the coefficients table is 62.29% greater than the partial correlation value of the other independent variables. customer value variables, customer satisfaction, and relationship marketing simultaneously have a significant effect on verified customer loyalty, customer value variables, customer satisfaction, and relationship marketing partially have a significant effect on proven customer loyalty and relationship marketing variables have a dominant influence on proven customer loyalty the truth. The most dominant variable is the relational marketing variable (X3) because the partial correlation value in the coefficients table is 62.29% greater than the partial correlation value of the other independent variables. customer value variables, customer satisfaction, and relationship marketing simultaneously have a significant effect on verified customer loyalty, customer value variables, customer satisfaction, and relationship marketing partially have a significant effect on proven customer loyalty and relationship marketing variables have a dominant influence on proven customer loyalty the truth. The most dominant variable is the relational marketing variable (X3) because the partial correlation value in the coefficients table is 62.29% greater than the partial correlation value of the other independent variables. customer value variables, customer satisfaction, and relationship marketing simultaneously have a significant effect on verified customer loyalty, customer value variables, customer satisfaction, and relationship marketing partially have a significant effect on proven customer loyalty and relationship marketing variables have a dominant influence on proven customer loyalty the truth.

Penelitian di Kecamatan Bawen dan Jambu Kabupaten Semarang dilaksanakan pada bulan Mei- September 2009. Hasil penelitian sudah dipublikasikan menjadi lima judul aspek keilmuan di media publikasi. Artikel ini merupakan rangkuman dari tiga publikasi yang sesuai dengan judul makalah, tentang eksterior, genetik dan reproduksi induk domba prolifik.  Tujuan penelitian untuk mengetahui performa eksterior, genetik dan reproduksi yang dapat digunakan sebagai dasar seleksi induk domba prolific yang baik. Penelitian dilakukan menggunakan metode survey dengan peternak sebagai responden dan induk dombanya sebagai materi penelitian. Penentuan materi secara porpusive sampling yaitu induk yang sudah pernah beranak minimal 3 kali. Materi dibagi menjadi tiga kelompok yaitu berkemampuan beranak tunggal (A1), kembar dua (A2) dan kembar lebih dari dua (AL2). Paremeter yang diamati, performa ekterior, genetik dan reproduksi. Hasil penelitian menunjukkan bahwa sifat eksterior kualitas induk domba AL2, ekornya tipis 88,25%, muka cembung 52,94%, telinga kecil 82,35% dan tubuh pendek 82,35%. Sifat eksterior kuantitatif induk domba AL2 mempunyai panjang tubuh 63,00+4,94 cm, lebar pinggul 19,88+5,81 cm, panjang tulang ileum 27,59+11,39cm dan lingkar dada 73,29+17,94 cm. Genetik domba AL2 yang memiliki pasangan genetik homozigot CpFCpF dan AmlBAmlB masing-masing mencapai 88,24% sedangkan lokus genetik lainnya berkisar 50,50-69,39%. Berahi setelah beranak domba AL2, 71,7+25,50 hari, lama estrus 18,33+4,81 jam dan jarak beranak 231,60+20,10 hari. Kesimpulan induk domba yang prolifik memiliki penampilan eksterion kualitatif dan kuantitatif, lokus Ceruloplasmin dan Amilase-I, berahi setelah beranak, lama estrus dan interval beranak, sangat berbeda dengan kelompok domba non-prolifik.
