Abstract

Kajian ini merupakan tahap awal dari kajian yang bertujuan menentukan ketebalan minimal lapisan laminasi FRP (Fiber Reinforced Plastic) pada kapal kayu ukuran 5-7 GT (Gross Tonnage). Konstruksi laminasi FRP bertujuan mengurangi kontak langsung bagian kapal dengan air disekitarnya serta mampu menahan benturan kapal ketika sandar pada dermaga khususnya bagian kasko kapal. Saat ini laminasi FRP dilakukan berdasarkan keahlian dan pengalaman yang dimiliki oleh pengrajin. Tujuan dari kajian ini untuk mengetahui kekuatan benturan pada kapal yang akan dijadikan acuan untuk menentukan ketebalan laminasi FRP. Metode yang digunakan adalah dengan identifikasi dimensi utama kapal, kecepatan kapal dan kekuatan benturan yang kemudian dianalisis secara deskriptif numerik. Data diperoleh dari 13 kapal sampel selama bulan Oktober-Desember 2019. Hasil dari penelitian ini menunjukkan bahwa kapal yang digunakan termasuk towed or dragged gear. Dimensi utama kapal dengan rata-rata Loa 9,5 m; Bmax 3,2 m; D 1,2 m dengan ton displacement 13,6 ton/m3. Kecepatan kapal ketika terjadi benturan pertama mengalami penurunan berkisar 0,4-1,0 m/s atau sekitar 20-75%. Kekuatan benturan yang terjadi pada kapal ketika benturan pertama berkisar 7,13-87,48 kN.m. Oleh karena itu, kekuatan bentur yang akan dijadikan acuan dalam menentukan ketebalan lapisan laminasi FRP pada kapal kayu adalah sebesar 87,48 kN.m.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) have an essential role in Indonesia’s economy, yet technological limitations often constrain productivity and competitiveness. D’Lor Bakery, located in Banyuwangi, previously relied on a conventional oven with limited capacity and uneven heat distribution, resulting in inconsistent product quality, high defect rates, and restricted production. To address these challenges, the Community Partnership Program (PKM) introduced a Gas Rotary Oven with automatic thermo control and gas leak detection. This innovation features a rotary rack system ensuring even heat distribution, a digital temperature control mechanism to stabilize baking conditions, and an MQ-5 sensor integrated with an automatic shut-off valve to enhance workplace safety. The implementation included design, training, and operational trials with a capacity of 56 trays per cycle. Results showed significant improvements: production capacity increased from 24 trays per cycle to 56 trays, with total output rising from 120 trays to 280 trays within five hours. Raw material processing also improved, from 10–15 kg of flour per cycle to 25–50 kg, while defective products decreased from 15–20% to 5–7%. Thermo control reduced temperature deviations by 15%, directly improving energy efficiency and lowering unit production costs. Economically, monthly revenue increased from IDR 4–5 million to IDR 8–12 million, with profit margins rising from 20% to 30%. Overall, the Gas Rotary Oven technology not only enhances productivity and consistency but also strengthens energy efficiency, product quality, and operational safety, making it a replicable solution for MSMEs in the bakery industry.

Abstract

The pitot tube is a component in the fuselage to measure the pressure generated by air movement or wind, while the placement of the pitot tube is usually on the wing. A trivial thing that can be fatal is that before flying, sometimes the pilot/flight instructor neglects to remove the pitot tank cover. This negligence resulted in the malfunctioning of the Air Speed Indicator (ASI), Vertical Speed Indicator and Altimeter. Appropriate technology in the form of a pitot tube cover with a warning using an ultrasonic sensor with the support of artificial intelligence technology using Arduino has been applied to the Piper Seneca V aircraft to prevent negligence in removing the pitot tube cover before flying. The Piper Seneca V has been chosen as the object of the application of technology because the Piper Seneca V type aircraft is of the low wing type so that the pitot tubes are not visible when not inspecting the underside of the aircraft's wings. During 30 days of testing with 12 hours of testing time each day and exposure to different temperatures and humidity each day, both battery life and component resistance can be ensured that they are still in optimal conditions. During testing in the simulation room, the tool worked well with a 1 meter object detection configuration. Using a 3.7 volt battery with a storage capacity of 1600 mAh can make the device last for 4 days with 2 hours of recharging time.

Abstract

In an increasingly competitive business world with ever-increasing customer demands for the quality of services and goods, customer satisfaction and loyalty have emerged as crucial issues in today's marketing management. Under such conditions, business entities must identify the key elements that shape satisfaction and how these contribute to building customer loyalty. This paper aims to examine the nature of study results on the determinants of satisfaction and loyalty through an evaluation of several recent empirical studies. Two key questions are addressed: which elements most strongly influence customer satisfaction, and what is the intermediary function of satisfaction in explaining the relationship between marketing variables such as service quality, cost, brand image, and trust with customer loyalty. The technique employed is a qualitative literature review through a search of articles using Google Scholar and Publish or Perish (PoP). Key terms used include customer satisfaction, customer loyalty, service quality, and trust. Of the 50 articles found in the initial phase, 15 met the inclusion standards and were thoroughly reviewed. The evaluation findings reveal three dominant patterns: service and product quality are the most stable factors driving satisfaction; cost and brand image serve as supporting factors; and trust acts as an important intermediary variable. This evaluation confirms that customer satisfaction is a key component in strengthening loyalty. Future studies are recommended to expand the scope of business sectors, use a more comprehensive structural framework, and utilize a wider variety of methodological techniques.

Abstract

This research aims to examine the effect of the avgas-ethanol fuel mixture on the fuel spray temperature. The research was carried out using a pressurized tube which was sprayed into the mock up which was assumed to be an aircraft combustion chamber with a pressure of 2 bar and a distance of 7,73 cm which would later be sprayed using pure avgas, a mixture of avgas and ethanol namely A80E20 and A60E40 then added with a temperature sensor at the end nozzle, center of jet, and impact wall. The spray temperature can result in incomplete combustion and result in higher exhaust emissions and also damage to the engine if it does not match the temperature capacity of the combustion chamber walls. The spray temperature results for the A60E40 fuel mixture are the lowest temperature, namely 25o-18.2oC and knowing that the more fuel is mixed, the lower the temperature of the fuel.

Abstract

The throttle is a device on the Cessna 172s training aircraft which is used to increase the amount of air used during combustion. To help overcome difficult throttle adjustments, special tools are needed in the form of a tracker. The existence of representative and useful tools to make things easier and save costs is really needed, therefore research to create work aids currently needs to be increased. Tool testing is also very important in knowing the maximum working point of the tracker tool which can determine properties such as shear elastic modulus, torsional yield strength and rupture modulus. The torsion test results consist of two parameters, namely the torsional moment parameter and the shear stress parameter. The tool that has been created in this research will analyze torsional strength using simulation.
