SMA Kristen 1 Surakarta is one of four private Christian high schools in Surakarta, with the hope that the school can guide and lead students to true, Bible-based teachings and glorify God. However, most Christian teachers still have difficulties integrating biblical Christian worldview into their learning and life. Christian ministry with sustainable activity programs needs to be carried out by providing guidance, training, and coaching for teachers. The implementation method is carried out through 3 stages, namely: 1) pre-implementation, which carried out with situation analysis and activity program planning in collaboration with partners; 2) implementation is carried out with 3 times session for teachers and staffs, offline and online; and 3) post-implementation, which are evaluation and follow-up plan. The expectation is that SMA Kristen 1 Surakarta will have the capital to carry out Christian faith-based learning that is biblical and in line with the government curriculum. The results and impact of this community service (PkM) activity are useful for teachers to develop true Christian learning which can be seen from the survey results after the training held. The conclusion is that this PkM has succeeded in having a positive impact on teachers in understanding Christian education to be able to develop correct Christian learning. Thus, this PkM activity will continue to be carried out sustainably in the next academic year targeting training and practical guidance in implementing Christian worldview in teaching and learning.Sekolah Kristen merupakan rekan kerja Allah yang dipanggil sebagai pelayan dalam misi pendidikan untuk mengajarkan kebenaran tentang Allah. SMA Kristen 1 Surakarta merupakan salah satu dari empat SMA Kristen swasta di Surakarta, yang diharapkan dapat membimbing dan menuntun siswa pada ajaran yang benar dan berlandaskan Alkitab serta memuliakan Allah.

Indonesia’s Preparedness to Ratify the United Nations Convention on Contracts for the International Sale of Goods (CISG)
Get PDFIntegrated international trade requires legal certainty that reduces transaction costs and mitigates disputes across jurisdictions. Although most of Indonesia’s major trading partners have ratified the United Nations Convention on Contracts for the International Sale of Goods (CISG), Indonesia remains a non‑Contracting State. This situation often forces domestic parties to accept foreign governing laws or international arbitration, resulting in legal uncertainty and higher transaction costs. The present study analyses regulatory gaps between Indonesian commercial contract law (including the Civil Code, Commercial Code and Trade Law No. 7 of 2014) and the CISG, evaluates the practical implications of non‑ratification, and formulates pragmatic strategies for harmonisation. Employing normative legal analysis and comparative policy review, the paper recommends staged harmonisation involving targeted legislative updates, model transitional contract clauses and capacity‑building for institutions and market participants. These measures aim to strengthen legal certainty and enhance Indonesia’s competitiveness in cross‑border trade.

PENGARUH PENAMBAHAN GENERATOR HHO TERHADAP TEGANGAN BATERAI PADA SEPEDA MOTOR MATIC
Get PDFAs energy demand increases and fossil fuel resources become limited, oxyhydrogen gas (HHO) has been developed as an alternative fuel produced through water electrolysis. This study aims to determine the effect of adding an HHO generator on the battery voltage of automatic motorcycles. The research was carried out through experimental testing under three conditions: stationary (switch ON, engine off), engine running, and operational (in motion). The parameters analyzed include changes in battery voltage and power consumption by the HHO system. The test results show that the use of the HHO generator causes a faster drop in battery voltage under engine-off conditions, with a decrease of 1.06% compared to 0.69% without HHO. Under engine-on conditions, the average battery voltage decreased by 4.05% due to the load from the HHO generator, although still within the normal operating range. In operational conditions, the battery voltage remained stable or even slightly increased, indicating that the alternator was able to supply the power demand of the HHO system. The power consumption of the HHO generator was recorded at approximately 49.84 watts in stationary conditions and 54.27 watts during operation. It can be concluded that the addition of the HHO generator affects the battery performance and adds an electrical load, but does not significantly disrupt the system\u27s stability as long as the vehicle\u27s electrical components are in good condition.Seiring meningkatnya kebutuhan energi dan terbatasnya sumber daya fosil, gas oxyhydrogen (HHO) dikembangkan sebagai bahan bakar alternatif yang dihasilkan melalui elektrolisis air. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan generator HHO terhadap tegangan baterai pada sepeda motor matic. Penelitian dilakukan melalui pengujian eksperimental pada tiga kondisi yaitu: kondisi stasioner (switch ON, mesin mati), kondisi mesin menyala, dan kondisi operasional (berjalan). Parameter yang dianalisis meliputi perubahan tegangan baterai dan konsumsi daya oleh sistem HHO. Hasil pengujian menunjukkan bahwa penggunaan generator HHO menyebabkan penurunan tegangan baterai lebih cepat pada kondisi mesin mati, dengan penurunan sebesar 1,06% dibandingkan 0,69% tanpa HHO. Dalam kondisi mesin menyala, tegangan rata-rata baterai menurun sebesar 4,05% akibat beban dari generator HHO, meskipun masih dalam rentang kerja normal. Pada kondisi operasional, tegangan baterai cenderung stabil bahkan sedikit meningkat, menandakan bahwa alternator mampu menyuplai kebutuhan daya dari sistem HHO. Konsumsi daya oleh generator HHO tercatat sekitar 49,84 Watt saat stasioner dan 54,27 Watt saat operasional. Dapat disimpulkan bahwa penambahan generator HHO memengaruhi karakteristik kerja baterai dan menambah beban kelistrikan, namun tidak mengganggu kestabilan sistem secara signifikan selama komponen kelistrikan kendaraan dalam kondisi baik
