Abstract

Padi merupakan tanaman pangan utama di Indonesia yang kaya karbohidrat sehingga menjadi makanan pokok masyarakat Indonesia. Dan untuk meningkatkan produksi padi, tidak hanya dengan memperluas areal pertanaman dan peningkatan teknik budidaya saja, tetapi perlu diperhatikan dalam penanganan panen khususnya dipemisahan padi yang harus tepat. Berdasarkan profil Kabupaten Sampang tahun 2017, produk unggulan daerah dalam sektor pertanian adalah padi. Oleh karna itu produksi padi harus lebih ditingkatkan agar dapat memenuhi kebutuhan sektor pangan masyarakat. Salah satu upaya meningkatkan produksi padi adalah dengan mengoptimalkan proses pemisahan gabah padi. Dalam artikel ini dibuat alat pemisah gabah padi dengan memanfaatkan sistem cyclone sehingga padi isi yang lebih berat akan terpisah dengan padi kosong yang lebih ringan. Dengan memanfaatkan gaya sentrifugal padi isi yang lebih berat akan terlempar keluar menuju penampungan padi isi. Sedangkan padi kosong yang ringan akan turun keluar ke penampungan padi kosong. Alat ini berukuran 80 x 40 x 80 cm. Dengan kapasitas 100 kg/jam, alat ini mampu meningkatkan produktivitas pekerjaan panen padi. Alat ini dihibahkan pada Kelompok Tani Bandar Kumala di Desa Karang Dalam, Kecamatan Sampang.

Abstract

The coastal area of ​​Madura has many fishing boats or fishing vessels of various types and sizes. The construction of traditional ships is carried out by groups of workers or traditional shipyards which are not permanent, technological readiness is still minimal, and the workforce is very limited. Especially in traditional shipyards in the coastal area of ​​Madura or throughout Indonesia's coastal areas, which still rely on skills from generation to generation, so it is difficult to achieve the ship size desired by the customer, even the deviation of the size in tons can reach 25 percent. This situation shows the weakness of the technology applied in the traditional shipbuilding industry. Therefore, the technology of dowel making machine for making wooden dowels is carried out 3 in 1 with the function of shaving wood, cutting wood as desired and sharpening pegs or wood. All work is done in one machine which can be done automatically by setting the desired peg size and running with a microcontroller system. Tests have been carried out on a 3 in 1 dowel machine using 2 motors, the average time is equal to or more than 1 minute/1 piece of peg. Testing the tool using 1 motor obtained an average time of less than 30 seconds to produce 1 wooden peg.

Abstract

Indonesia, as a country predominantly surrounded by the sea, holds significant potential in marine resources, fisheries, and other maritime fields. However, there is still a lack of awareness and understanding among the Indonesian population regarding these maritime aspects. Currently, there are various media and information sources related to this topic, ranging from websites and applications to supporting information systems. Nevertheless, users often struggle to find and comprehend this information easily and comprehensively. Existing information systems tend to be fragmented or operate independently, leaving many laypeople unable to fully optimize the existing potential. To address this, researchers aim to identify and model a comprehensive and integrated information system focused on marine and other maritime resources, known as SI-LAUT The research method employed in this study consists of literature review, stakeholder identification based on the Penta-Helix model, analysis of the existing system, and gap analysis in comparison to previous research that focused on the implementation of other maritime and marine information systems. The results of this research consists of a recommendation for an information system development model that can assist various stakeholders based on the Penta-Helix Model. These stakeholders include government bodies, entrepreneurs, academics, as well as the general public or other communities. The goal is to optimize the management and utilization of Indonesia’s marine resources, ultimately positioning it as a global maritime powerhouse.

Abstract

This study reports the synthesis of biodiesel from locally sourced Waste Cooking Oil (WCO) using sodium hydroxide (NaOH) catalyst. The main objective of this research is to assess the feasibility of utilizing WCO-based biodiesel as a sustainable alternative fuel by analyzing its physicochemical properties and application in a Yanmar® TF 70 LY-DI diesel engine. The production process involved degumming, acid-catalyzed esterification, and base-catalyzed transesterification to address the high free fatty acid content of WCO. The resulting biodiesel met ASTM D6751 standards, with a kinematic viscosity of 5.06 cSt, a flash point of 164°C, a density of 885 kg/m3, a FAME yield of 98.17%, and an acid number of 0.12 mg-KOH/g. Engine tests were performed using blends from B10 to B40 and benchmarked against pure diesel. Results showed that B10 and B20 blends maintained comparable engine performance, while higher blends (B30–B40) exhibited reductions in power and torque and increased Specific Fuel Consumption (SFC). CO emissions decreased significantly with increasing biodiesel content, whereas NO and NOx emissions rose due to higher combustion temperatures. These findings demonstrate the technical feasibility and environmental benefits of WCO-derived biodiesel, particularly at lower blend ratios (≤ B20), as a locally available and sustainable fuel. The study is limited to laboratory-scale testing on a single-cylinder engine without long-term durability assessments, which should be addressed in future studies.

Abstract

Carbon steel is a type of alloy steel consisting of various elements, especially iron (Fe) and carbon (C). In general, the properties of steel are affected by the percentage of carbon and the microstructure of steel which is affected by steel composition and heat treatment. The welding process can change the structure and composition of steel. The safety of weld results can be carried out after welding using a heat treatment process. This tempering aims to obtain better and desired mechanical properties. Tempering is carried out using temperatures of 200⁰C, 250⁰C and 300⁰C with cooling using air media and mechanical testing will be carried out.The results of this research showed that tempering temperature had an effect on the hardness value of medium carbon steel resulting from FCAW welding. The hardness value at a temperature of 200℃ was 54.75, a temperature of 250℃ was 53.00 and a temperature of 300℃ was 52.04. The higher the temperature, the lower the hardness value and conversely, the lower the tempering temperature, the higher the hardness value.Keywords: Welding, Tempering, Hardness
