Abstract

In stationary diesel motors, the temperature reduction is carried out by cooling water and the temperature of the cooling water is lowered by environmental or natural air. This will be problematic if used in areas with relatively limited water supplies, where for stationary diesel motors of the above type, cooling water is always reduced and must be added. Throughout the operation. Apart from overcoming the problems above, the aim of this research is to obtain the most economical reduction in fuel consumption by using a system for reducing the temperature of the load wheel cooling water on stationary diesel motors. The research method uses the independent variable in the form of a load wheel with variations in the number of fins and variations in fin angle, the dependent variable is the rate of increase in heat and fuel consumption while the control variable is taken as room temperature during the test. The test results show that the greater the angle of the fin to the center line of the flywheel has an effect, where the greater the fin angle of the flywheel will cause the rate of increase in water temperature in the reservoir to be slower than the rate of increase in water temperature with a larger angle small, even though the effect is small, it results in a reduction in fuel use to an average 50% The conclusion obtained is that the use of a load wheel cooling water temperature reduction system on stationary diesel motors is better than the use of a standard (natural) cooling system. Almost the same as a radiator system.

Abstract

This article describes a descriptive qualitative reseach on the leadership style of the principal of SMK Negeri 5 Kendal in improving the quality of education. This article discusses the implementation of educational management and leadership at SMK Negeri 5 Kendal. Education has an important role in shaping the nation's future, and educational leaders play a vital role in managing educational institutions. This report aims to identify educational leaders at SMK Negeri 5 Kendal and their contribution to the quality of education. Through observations and interviews with school principals, teachers and students, it was found that educational management includes curriculum planning, human resource management, as well as monitoring and evaluation. However, challenges such as lack of government support, minimal training for school principals, and teacher resistance to change are still faced. Improvement efforts through professional training, better communication, and implementation of school-based management are proposed to increase the effectiveness of educational management and leadership. Observation results show that although challenges exist, the innovations implemented have a positive impact on the learning process and student achievement.

Abstract

Proses perancangan kontrak hingga menjadi akta autentik dalam praktik kenotariatan dengan menekankan analisis terhadap ketentuan hukum perjanjian dalam KUH Perdata, asas-asas kebebasan berkontrak, serta kewenangan notaris sebagaimana diatur dalam UU Jabatan Notaris. Notaris berperan penting memastikan keabsahan dan kepastian hukum suatu kontrak melalui verifikasi identitas, legalitas dokumen, kejelasan klausula, dan kesesuaian dengan peraturan perundang-undangan. Meskipun demikian, proses tersebut sering menghadapi hambatan seperti ketidaklengkapan dokumen, ketidakjelasan objek perjanjian, minimnya literasi hukum para pihak, dan ketidaksinkronan regulasi, yang berpotensi melemahkan kekuatan pembuktian akta autentik. Oleh karena itu, ketelitian notaris, peningkatan pemahaman hukum para pihak, serta perbaikan tata kelola pemeriksaan dokumen menjadi kunci untuk memastikan akta autentik tetap memberikan kepastian, ketertiban, dan perlindungan hukum.

Abstract

Technological advances in the industrial era 4.0 mean that various things must prioritize convenience and efficiency in carrying out daily work such as carrying out automatic maintenance and control in the home. This has made many people able to produce various forms of technology that can be controlled automatically and help with work. people who can't take up much time. OT is a technology built to provide ease of work that can be connected to each other using the internet. One use of IoT technology is in the household sector to feed ornamental fish according to need and monitor remaining feed. This tool is designed for NodeMCU as control and an internet connection that is integrated with the Blink application. This tool consists of an HC-SR04 sensor input and a DS3231 RTC timer. The output of this tool uses a servo motor to open and close the contents of the fish feed. Arduino IDE software is used in NodeMCU coding and the Blynk application is used to connect the smartphone and NodeMCU. Based on the results of testing carried out, the system success rate has an average of 95% success. Meanwhile, the average delay is 0.052367 milliseconds.

Abstract

Pertumbuhan ekonomi Indonesia pada periode 2020–2025 mengalami dinamika yang signifikan akibat berbagai guncangan ekonomi, baik yang bersumber dari faktor domestik maupun global. Perubahan kondisi makroekonomi seperti inflasi, suku bunga, dan nilai tukar rupiah menjadi faktor penting yang memengaruhi stabilitas dan kinerja pertumbuhan ekonomi nasional. Penelitian ini bertujuan untuk menganalisis pengaruh variabel makroekonomi terhadap pertumbuhan ekonomi di Indonesia dalam jangka pendek dan jangka panjang. Metode yang digunakan dalam penelitian ini adalah Autoregressive Distributed Lag (ARDL) dengan memanfaatkan data time series bulanan periode 2020–2025 yang bersumber dari Badan Pusat Statistik (BPS) dan Bank Indonesia. Metode ARDL dipilih karena mampu mengestimasi hubungan jangka pendek dan jangka panjang secara simultan serta dapat digunakan pada data dengan tingkat integrasi yang berbeda. Hasil penelitian diharapkan mampu memberikan gambaran empiris mengenai peran variabel makroekonomi terhadap pertumbuhan ekonomi Indonesia serta menjadi bahan pertimbangan bagi pemerintah dan otoritas moneter dalam merumuskan kebijakan ekonomi yang efektif dan berkelanjutan.

Abstract

Latar belakang penelitian ini bertujuan untuk mengetahui dan menganalisis peran Pemuda Muhammadiyah dalam penguatan dakwah Islam di Desa Wonosari, Kecamatan Pekalongan, Kabupaten Lampung Timur. Latar belakang dari penelitian ini adalah maraknya pengaruh budaya Barat yang secara masif masuk ke Indonesia tanpa filter nilai, sehingga menyebabkan krisis moral, khususnya di kalangan generasi muda. Masa remaja merupakan masa transisi yang rentan terhadap penyimpangan perilaku, dan jika tidak ditangani secara serius, dapat berdampak buruk pada tatanan sosial masyarakat. Hasil penelitian menunjukkan bahwa Pemuda Muhammadiyah memainkan peran yang sangat penting dalam memperkuat dakwah dan membina generasi muda. Peran ini diwujudkan melalui berbagai kegiatan keagamaan, sosial, dan edukatif seperti kajian rutin bulanan, sharing time, safari Ramadhan, bakti sosial, serta pembinaan kader. Kegiatan-kegiatan tersebut tidak hanya berfungsi sebagai media dakwah, tetapi juga sebagai sarana pembentukan karakter, peningkatan wawasan keislaman, dan penguatan semangat pengabdian sosial di kalangan pemuda. Strategi dakwah yang diterapkan mencakup empat pendekatan utama, yaitu: dakwah bil hikmah (edukatif), dakwah bil mau’izhah hasanah (emosional dan moral), dakwah bi al-hal (keteladanan dan aksi nyata), serta dakwah digital (melalui media sosial). Keberhasilan dakwah ini ditopang oleh sejumlah faktor pendukung, baik internal maupun eksternal, seperti semangat dan militansi anggota, dukungan tokoh masyarakat, struktur organisasi Muhammadiyah yang kuat, ketersediaan sarana dan prasarana, sinergi dengan organisasi otonom dan Amal Usaha Muhammadiyah (AUM), partisipasi aktif masyarakat, serta kemampuan adaptasi terhadap teknologi. Kata kunci: Dakwah; krisis moral; pemberdayaan pemuda; pemuda muhammadiyah; strategi dakwah
