Abstract

Kerupuk merupakan suatu jenis makanan ringan yang sudah lama dikenal oleh sebagian besar masyarakat Indonesia. Kerupuk dapat dikonsumsi sebagai makanan selingan maupun sebagai variasi dalam lauk pauk. Sebagai komoditi dagangan kerupuk termasuk kedalam jenis produk industri yang mempunyai potensi cukup baik. Saat ini pemasarannya berkembang tidak hanya di dalam negeri, tetapi juga di luar negeri. Pencetakan adonan kerupuk dimaksudkan untuk memperoleh bentuk dan ukuran yang seragam. Keseragaman ukuran penting untuk memperoleh penampakan dan penetrasi panas yang merata sehingga memudahkan proses penggorengan dan menghasilkan kerupuk goreng dengan warna yang seragam.  (Koswara, 2009). Mesin pencetak kerupuk ini adalah suatu peralatan yang berfungsi untuk mencetak kerupuk uyel dengan pola kurva lissajous. Kapasitas yang direncanakan adalah satu buah kerupuk dicetak dari satu buah nozzle sehingga diharapkan untuk pencetakaanya per 4 jam adalah 1500 pola, sekitar sembilan detik per satu pola kerupuk dengan dimensi kerupuk yang tercetak berupa persegi dengan panjang 65 mm dan lebar 65 mm dengan berat rata-rata ± 7 gram per kerupuknya dan diameter lubang nozzle yang digunakan 3 mm. Dengan adanya perancangan mesin pembuat pola kerupuk ini diharapkan dapat meningkatkan produktivitas pada proses pencetakan kerupuk yang selama ini dilakukan dengan cara tradisional dan kebersihan produk dapat terjaga selama proses pencetakan.

Abstract

This article uses qualitative research methods and literature to collect information from various written sources. This study utilizes secondary data sources, including digital literature such as websites, journals and bulletins, to explore the factors that influence Indonesia’s manufacturing industry and contribute to the country’s economic growth. This research covers both the barriers and drivers of industrial improvement. Investment in the industrial sector plays an important role in economic growth, making it one of the main areas of interest for domestic investors. The industrial sector is considered a significant contributor to development, as evidenced by the steady growth of Indonesia’s GDP from year to year. Thus, it is the main driver of the country’s economic progress.

Abstract

Passenger ship accidents in Indonesia’s domestic waters are frequently linked to overloading and stability failures, particularly on non-classed vessels with open decks. This study proposes an analytical method to determine the optimal passenger capacity based on intact stability survival criteria. The method begins with hydrostatic calculations of the hull to generate the KN curve, which is then adjusted for the mass distribution of the vessel and passengers to produce the actual GZ curve. Optimization is performed iteratively by comparing the calculated righting moment (Mst) with the regulatory criterion moment (Mkr), following both BKI and ISO 12217-1:2015 standards, while also accounting for the limiting condition at the downflooding angle. A case study on a V-hull boat (L = 10.5 m; B = 3.2 m; H = 1.4 m) reveals a substantial divergence between the two regulatory frameworks. Under light displacement (LWT = 1 ton), ISO permits up to 138 passengers, whereas BKI limits capacity to only 17. Conversely, at a high LWT of 8 tons, ISO does not allow any passengers, while BKI still permits approximately 29. Validation against Maxsurf software demonstrates excellent agreement (R² = 0.9993), confirming the reliability of the developed program. These findings establish that the proposed method is both valid and practical, offering a technical guideline for determining the safe passenger capacity of non-classed open-deck vessels operating in domestic waters.
