Abstract

In a common rail diesel engine system, the entire fuel system is regulated electronically by a computer device called the ECU.  With this sensor manipulator tool, it is hoped that you will be able to change the output of the fuel pressure sensor to modify the ECU input. This makes it possible to change the power produced by the vehicle and reduce fuel consumption. This research is using experimental methods. The initial step is to take vehicle power test data under normal conditions, with the fuel pressure sensor output voltage at 1.28 V, reduced by 0.2 (1.08 volts), decreased by 0.1 (1.18 volts), increased by 0,1 (1.38 volts), and up 0.2 (1.48 volts). The results of this research show that the highest power at a speed of 80 km/h occurs at a voltage of 1.38 volts and 1.48 volts, with a power of 103 HP. Optimal fuel pressure produces good misting, ensures the mixture of fuel and air in the combustion chamber is homogeneous, and produces maximum power. The results of the fuel consumption test show that the lowest fuel consumption occurs at a vehicle speed of 40 km/hour with a fuel pressure sensor voltage of 1.38 volts, which is around 0.615 cc/second. It can be concluded that a voltage of 1.38 volts produces the most optimal fuel pressure. The throttle valve and pedal openings are still slightly open, so the amount of fuel entering the combustion chamber is also limited, so fuel consumption is very economical.

Abstract

One of the negative impacts of the development of digital technology is the weakening of authoritative facts and the increasing dominance of opinion in the public sphere. This situation strengthens the spread of religious disinformation in digital media, which has the potential to shift the authenticity of Islamic thought. Departing from this fact, this study seeks to analyze how da'wah communication strategies can function as a mechanism to counter religious disinformation in the post-truth context. This study uses a qualitative method with a literature study approach to articles or books published between 2016 and 2024. The data was obtained through a systematic search process in the Google Scholar database, books, and various research results. The literature selection was based on the following criteria: relevance to the theme of digital da'wah communication, media literacy, and post-truth studies; and publications that provide empirical findings or theoretical frameworks related to countering disinformation. The analysis results show three main findings: first, implementing effective digital da'wah communication practices in the post-truth era consistently utilizes the principle of ttabayyun as an information verification mechanism; second, increasing digital literacy among da'i and audiences has been proven to be a factor that directly reduces vulnerability to misinformation and disinformation; Third, creative, data-driven da'wah content that adheres to digital communication ethics has a higher level of reach and public trust. This third finding demonstrates that digital da'wah communication plays a crucial role as a social instrument for maintaining the integrity of religious information amidst the dominance of opinion in the post-truth era.

Abstract

Nabi Idris AS dikenal sebagai salah satu nabi yang memiliki keistimewaan dalam hal ilmu pengetahuan, ketekunan, dan spiritualitas. Dalam literatur Islam, beliau disebut sebagai sosok yang pertama kali memperkenalkan tulisan, menjahit pakaian, serta meneliti pergerakan bintang. Artikel ini bertujuan untuk mengkaji keteladanan Nabi Idris AS dalam konteks dakwah, terutama terkait pentingnya ilmu dan amal dalam kehidupan seorang dai. Penelitian ini menggunakan pendekatan kualitatif melalui studi pustaka dengan analisis tafsir dan hadis. Hasil kajian menunjukkan bahwa metode dakwah Nabi Idris AS mengintegrasikan ilmu, amal, dan hikmah, sehingga dapat menjadi model dakwah ilmiah dan beradab di era modern.

Abstract

Peradaban Islam mengalami fondasi yang kuat sejak masa Khulafaur Rasyidin, yang meliputi Abu Bakar, Umar bin Khattab, Utsman bin Affan, dan Ali bin Abi Thalib. Kepemimpinan mereka tidak hanya bersifat administratif, tetapi juga menjadi teladan integrasi nilai spiritual, etika, hukum, dan kesejahteraan sosial. Studi ini menggunakan pendekatan interdisipliner dengan metode kualitatif analisis literatur klasik dan kontemporer untuk mengeksplorasi praktik kepemimpinan, penerapan syariah, dan pembangunan masyarakat pada periode tersebut. Hasil kajian menunjukkan bahwa struktur politik, sistem hukum, serta kebijakan sosial-ekonomi pada masa Khulafaur Rasyidin menekankan prinsip keadilan, kemaslahatan publik, dan pendidikan, yang relevan sebagai model pembangunan peradaban Islam kontemporer. Temuan ini mengindikasikan bahwa nilai-nilai kepemimpinan, etika, dan integrasi hukum-spiritual tetap dapat dijadikan pedoman dalam menghadapi tantangan modernitas dan transformasi sosial-politik.

Abstract

The fused deposition modeling (FDM) process is an additive manufacturing technique that fabricates 3D objects through layer-by-layer deposition of molten material. This study aims to determine the optimum process parameters for fabricating onyx-glass fiber composites with maximum impact strength. Onyx, a nylon-based filament filled with micro-carbon fibers, was selected because it is stronger and stiffer than conventional ABS and can be reinforced with continuous fibers. This optimization is important for lightweight structural components, such as electric-vehicle gears, where durability and resistance to dynamic loads are required. The Taguchi method with an L9 orthogonal array was applied, with three parameters investigated: filling density, number of wall layers, and number of glass fiber layers. Impact testing was conducted in accordance with ASTM D6110-10 using a Charpy impact tester. ANOVA results indicated that the number of glass fiber layers was the only factor with a statistically significant effect on impact strength at the 95% confidence level (P = 0.043), while the number of wall layers was statistically insignificant (P = 0.468). Filling density showed a marginal contribution to impact strength (P = 0.073). The optimum combination within the investigated parameter range was identified as 30% filling density, two wall layers, and 18 glass fiber layers, producing a maximum observed impact strength of 0.375 J/mm2.

Abstract

Produksi dari suatu usaha penangkapan ikan laut sebagian besar adalah berupa ikan segar yang segera dijual kepada konsumen, namun saat produksi melimpah seringkali hasil produksi tidak dapat terjual seluruhnya, sedangkan ikan laut memiliki sifat yang mudah rusak/busuk. Oleh karena itu, perlu dilakukan usaha untuk meningkatkan daya simpan dan daya awet produk perikanan pasa pasca panen melalui proses pengolahan maupun pengawetan. Penelitian ini menganalisis seberapa besar nilai tambah yang dihasilkan dari pengolahan kerupuk ikan pada usaha industri rumah tangga di Kecamatan Selakau Kabupaten Sambas. Penelitian ini menggunakan metode deskriptif. Lokasi penelitian yaitu di Desa Kuala dan Desa Parit Baru dengan dasar pertimbangan bahwa lokasi tersebut berdekatan dengan pesisir pantai yang mayoritas banyak mengolah kerupuk ikan. Populasi dalam penelitian ini sebanyak 27 pengusaha. Karena jumlah populasi sedikit, maka semua pengusaha diambil sebagai sampel. Analisis data dilakukan dengan menggunakan analisis nilai tambah pengolahan menurut Hayami. Hasil analisis data terdapat Nilai tambah yang berbeda "“ beda, Nilai tambah terbesar yang diperoleh pada usaha kecil rumah tangga adalah Rp 12.722 per Kg. Jika nilai tambah tersebut dibagi dengan nilai produk maka diperoleh rasio nilai tambah sebesar 28,78 %. Ini berarti dari Rp 44.200 per Kg nilai produk, 28,78 % merupakan nilai tambah dari pengolahan produk. Sedangkan nilai tambah terkecil dengan nilai Rp 8.089 per Kg, dengan rasio nilai tambah sebesar 19,03 % dari pengolahan produk, dan nilai tambah rata-rata sebesar Rp. 10.815,30 per Kg, dengan rasio nilai tambah sebesar 25,20 % per Kg dari pengolahan produk. Kata Kunci: Nilai Tambah, Industri Rumah Tangga, Kerupuk Ikan, Hayami
