Abstract

Tujuan penelitian ini adalah untuk menganalisis sinergitas lembaga kepolisian dalam pencegahan kejahatan oleh satuan fungsi kepolisian melalui pemolisian masyarakat guna memantapkan pemeliharaan keamanan dan ketertiban masyarakat (harkamtibmas). Metode yang digunakan dalam penelitian ini adalah metode bauran (mix method) antara metode deskriptif dengan metode survai. Sumber data digali melalui teknik pengumpulan data yang digunakan, terutama kepada narasumber/ informan penelitian yang terpilih sesuai dengan kriteria narasumber/ informan penelitian. Teknik pengumpulan data melalui studi dokumen. Teknik ini digunakan untuk informasi yang berkaitan dengan kegiatan pencegahan kejahatan, termasuk kegiatan penguatannya yang dilakukan melalui kegiatan polmas. Dokumen yang dimaksud dapat berupa pedoman, panduan, laporan, rencana kegiatan, MOU, dan dokumen pendukung lainnya yang relevan dengan isu penelitian. Teknik pengumpulan data melalui angket/ kuesioner yang akan disebarkan melalui google form.. Penelitian ini dilakukan di Polda Kalimantan Barat dan jajaran. Teknik analisis dilakukan melalui empat tahap yaitu pengumpulan data, reduksi data, penyajian data dan langkah terakhir adalah penarikan kesimpulan dan verifikasi. Hasil penelitian ini menunjukkan bahwa Sinergi eksternal pencegahan kejahatan yang dilakukan oleh Polda Kalbar dan jajaran telah berjalan cukup baik. Namun demikian, ada beberapa program atau pelaksanaan yang masih belum fokus pada aspek-aspek yang berkorelasi dengan munculnya kejahatan secara spesifik. Sinergi belum secara khusus mengintervensi faktor penyebab, faktor pendorong dan faktor pemicu munculnya kejahatan. Sinergi internal antara satuan fungsi dan satuan kewilayahan telah berjalan sesuai dengan tugas pokok dan fungsi masing-masing. Aspek yang perlu mendapatkan penguatan meliputi mekanisme sharing informasi, kordinasi penggunaan sumber daya dan metode untuk pencegahan kejahatan yang masih cenderung partial berbasis pada tugas pokok masing-masing.

Abstract

Crime science and police science have been well-developed in English-speaking countries, as evidenced in the literature. The two sciences are lacking in discussing Indonesia. This research will reveal crime and police science in Indonesia through the literature review. The method of this study is a narrative review. Articles, books, book chapters, and other grey literature (e.g., public documents) are examined to unearth the rise of crime science and police science in Indonesia. The themes used to investigate crime science and police science in Indonesia are constructed from a global literature review. The study concludes that crime science and police science exist in the literature. Nevertheless, the development is still lacking. This condition is caused by the lack of well-organized institutions facilitating the creation of literature. The police journals operated by the Indonesian National Police (INP/Polri) may become facilitating institutions for enhancing crime science and police science in Indonesia. Similar to the global literature, the development of the sciences is associated with police professionalisation, police education, and police research. Further studies are suggested to explore and assist the development of crime science and police science in Indonesia.

Abstract

This study aims to evaluate the performance of an LPG stove burner by assessing the flame temperature, fuel consumption, burner power, and thermal efficiency. The method employed is an experimental approach using a water boiling technique. The test materials used include 3 kg of LPG gas and water. The equipment utilized includes an SNI-compliant cooking stove, a pot, a digital scale, a rotameter flow meter, a gas regulator and hose, a stopwatch, a UT320D thermometer controller, an NPT stainless steel thermometer, and thermocouple sensor cables. The results show that during the first test with the stove set to the minimum setting, the average flame temperature at the burner reached 559.005 °C, with a maximum value of 589.2 °C. In the second test, with the stove set to the maximum setting, the average flame temperature reached 714.78 °C, with a maximum value of 769.3 °C. Fuel consumption was recorded at 0.391 kg in the first test and 0.545 kg in the second test. The burner power output was 1.754 kW in the first test and 2.225 kW in the second test. The thermal efficiency of the burner was recorded at 50.07% in the first test, increasing to 52.85% in the second test. The measurement and analysis of thermal efficiency and fuel consumption in this study can serve as a crucial guide in designing and developing burners for Stirling engines.
