Abstract

The objective of this this research was to produce worksheets with a generic science skills (GSS)-based on the lesson of pressure for class 8th in MTs Alfatah. According to Sugiyono (2011), the method is adapted from research steps that includes 9 stages of development. The result of tests on user response on the aspects of the attractiveness get score 3,18 with good category, the aspects of simplicity got score 3,07 with good category, and for the aspect of usefulness get score 3,14 with good category. While for the efectivity test results in the usage of product trial get 81,25%, student complete 65 of accomplishments criteria (or KKM). Therefore, GSS-based of students worksheets is worthy and efective to use as a learning media.Tujuan penelitian ini adalah menghasilkan LKS Berbasis KGS pada materi tekanan untuk kelas VIII MTs Alfatah Natar. Metode pengembangan diadaptasi dari langkah-langkah penelitian dan pengembangan menurut Sugiyono (2011) yang meliputi sembilan tahapan pengembangan. Hasil uji coba terhadap respon pengguna untuk aspek kemenarikan memperoleh skor 3,18 dengan kategori baik, aspek kemudahan memperoleh skor 3,07 dengan kategori baik, untuk aspek kebermanfaatan memperoleh skor 3,14 dengan kategori baik. Semetara itu, untuk hasil uji efektivitas pada uji pemakaian produk mencapai 81,25% siswa tuntas KKM 65. Dengan demikian, LKS berbasis KGS layak dan efektif digunakan sebagai media pembelajaran.Kata kunci: keterampilan generik sains, lembar kerja siswa, pengembangan

Abstract

Good product design is to pay attention to convenience side by referring to anthtropometry and ergonomics approach. Jap pressing tools in UKM AGAPE Pemalang still using simple tools require workers manually by pressing a well-cooked jenang with the help of wooden entong as a tool to flatten the jenang. Many weaknesses by using the previous pressing tools that cause the worker menjdi tired quickly. In this design using anthropometri and ergonomics approach in determining worker comfort level. Sample used from 31 employees. From this research it can be concluded that with the existence of worker pressing tools more comfortable to use the tool, besides more effective than the previous tool. As for suggestions that can be given is to pay more attention to creativity, creativity, innovation, and comfort levels of workers with the concept of ergonimis in order to produce the design results of a good product. In product design in addition to considering the ergonomic size should also pay attention to the strength and security when used.Keywords:Jenang Pressing Tool, Product Design, Anthropometry

Abstract

Ice Slush Machine uses a direct cooling vapor compression system. The primary refrigerant used in such a system mostly is hydrofluorocarbons (HFCs), such as R134a. R134a is a retrofit for refrigerant R-12 which is included in the chlorofluorocarbon (CFC) type of refrigerant. CFC-type refrigerants have a dangerous impact on the environment. Hydrocarbon refrigerant MC-134 is an alternative for R-134a because it has a low potential value for environmental damage. The secondary refrigerant used was propylene glycol and the product used was 3.5 liters of Coca-Cola. From the test results when the system using R134a had an average COPactual and an average COPcarnot of 2.6 and 4.55, respectively, and the energy consumption was 1.571 kWh with an average efficiency of 57%, while in a system with MC-hydrocarbon refrigerant 134 obtained an average COPactual and an average COPcarnot of 2.8 and 4.5, respectively and the energy consumption of 1.325 kWh with an average efficiency of 62%. Therefore, MC-134a had COP actual greater than R-134 and electrical energy consumption of MC-134 was less than R-134a.

Abstract

The purpose of this research is to make a Java-based savings and loan cooperative information system design to accelerate and facilitate performance in managing the search and storage of loan data at cooperatives as well as to produce a Java-based savings and credit cooperative information system. The research method used by researchers is the grounded research method, which is a research method based on facts and uses comparative analysis with the aim of conducting empirical generation, establishing concepts, proving theories, developing theories, collecting data and analyzing data in the same time. The results obtained are designing a savings and loan cooperative information system to assist in processing employee data. The construction of this information system is expected to simplify and provide maximum service for employees as well as to facilitate cooperative staff in collecting loan transaction data for reporting, data and information management processes become more effective, produce faster outputs and there is no misappropriation of loan data input or the occurrence of data duplication.

Abstract

This study provides a conceptual and normative analysis of two significant economic systems in Indonesia: Islamic (Sharia) economics and Pancasila economics. Although they originate from different ideological foundations, both exhibit numerous similarities in their core principles, fundamental values, and goals. Islamic economics is based on Islamic teachings that emphasize justice, balance, and the prohibition of usury (riba), focusing on public welfare (maslahah) and equitable wealth distribution. Meanwhile, Pancasila economics is rooted in the values of Pancasila, particularly the fifth principle, which prioritizes social justice for all Indonesian people, emphasizing cooperation (gotong royong) and the balance between individual and societal interests. The analysis results indicate that both systems share common values in rejecting extreme individualism and materialism, focusing instead on collective welfare through fair wealth distribution. The fundamental difference lies in their ideological approaches: Islamic economics adheres to Islamic law (the Qur'an and Hadith) with specific rules such as the prohibition of usury and the obligation of zakat, while Pancasila economics is more flexible and adaptable to Indonesia's pluralism. The implementation of both systems in Indonesia shows a synergy, such as the development of Islamic banking and Sharia cooperatives, aligning with the principles of Pancasila economics. This study recommends strengthening this synergy through inclusive economic policies and broader education on the shared values between Islamic and Pancasila economics. In conclusion, despite their conceptual differences, Islamic economics and Pancasila economics have the potential to complement each other in achieving social justice and collective welfare in Indonesia.
