Abstract

Road user safety is a crucial aspect of transportation infrastructure development, particularly in hilly areas where accident risks are higher than in flat areas. Sungai Jambur Village is a hilly area with winding roads, minimal lighting, and limited road safety facilities. These conditions have the potential to increase the risk of accidents, particularly at night and during inclement weather. This article discusses the implementation of cement pipe-based road reflectors as a simple, economical, and easy-to-implement innovation to improve road user safety in the area. The method used in writing this article is a descriptive study with a field observation approach and a literature review related to transportation safety. The results of the discussion indicate that the use of cement pipe-based road reflectors can improve driver visibility, help mark bends and road edges, and have a positive impact on traffic safety in the hilly areas of Sungai Jambur Village. In addition, the use of local materials in the form of cement pipes makes this program more efficient and sustainable.

Abstract

The cracking of gray cast iron castings in the form of pulleys can result in eroding the contact surface on the V-belt in its operation as a problem faced. The purpose of casting is to obtain a 4” diameter cast iron pulley, 40 mm thick pulley, 80 mm hub length, 18 mm axle hole, 50 mm hub diameter, and 72 mm inner diameter of the pulley belt groove. The casting method includes: design of a 4” diameter pulley with a hub length of 80 mm; making a sand mold without a core; drying the mold at 200oC; preparation of casting materials-equipment; melting cast iron up to 1,350oC with the addition of 10% scrap cast iron; casting molten metal into the sand mold; dismantling the casting, cutting the pouring bowl channel and riser; drilling an 18 mm diameter axle hole; turning the V-belt groove at a 38o angle with a depth of 15 mm; finishing; and quality-dimension-defect inspection. The casting results are cast iron pulleys with a diameter of 4”, pulley thickness of 40 mm, hub length-diameter of 80-50 mm, axle hole of 18 mm, inner diameter of the pulley belt groove of 72 mm without any cavity defects or cracks, total casting cost of IDR 100,000,-/unit and process duration of 6 minutes/unit which implies that the cast iron pulley can be used with a V-section rubber belt with a smooth contact surface.

Abstract

Air Circuit Breaker (ACB) is a protection device used in low- and medium-voltage panels, with air at atmospheric pressure functioning to extinguish arcs generated by switching processes or electrical disturbances. This study aims to analyze ACB components, wiring systems, threshold value calculations, and the electric tripping unit system. The research methods used include observation, interviews, and literature study. The results show that the ACB component testing produced an incoming current value of 2,000 A, with Ir set at 0.4, Lsd at 2, and Tr at 0.5. Based on these values, the ACB threshold limit is 800 A, while the Lsd current reaches 1,600 A. If the current passing through the ACB exceeds 1,600 A, the ACB will automatically trip and disconnect the circuit within 0.5 seconds. The pre-alarm is inactive at 85% because this position is the threshold point, while at 90% the pre-alarm becomes active as the current approaches the tripping threshold. Overall, the electrical tripping system activates automatically during overload or short-circuit conditions to protect the circuit.

Abstract

The ease of bending of nails when hammered into the cement concrete surface is a problem encountered in the field. The manufacturing objective is to obtain concrete nails with a diameter of 4 mm, a length of 50 mm that do not bend when hammered into the cement concrete surface. The manufacturing method includes: design of concrete nails with a diameter of 4 mm, a length of 50 mm; selection including the purchase of medium carbon steel, AISI 1045; straightening and reducing the wire rod (wire drawing) from a diameter of 10 mm to a diameter of 4 mm with 6 stages of reduction; cold forming (cold heading) of AISI 1045 material to form the nail head; cutting into the shape of the nail tip; and checking the quality-dimensions of the nails. The manufacturing results are concrete nails with a diameter of 4 mm, a length of 50 mm that do not bend easily when hammered into the cement concrete surface with a production cost of Rp 450,-/piece and a production duration of 45 seconds/piece which consequently means that the concrete nails can be nailed into the cement concrete surface without bending and can be produced on a small to medium industrial scale.

Abstract

The problem lies in the scarcity and relatively high price of 300 g plastic hammers on the market. The manufacturing goal is to obtain a 300 g plastic hammer, 30 cm long, 5x4 cm oval diameter, with a wooden handle. The manufacturing method includes: design of a plastic head mold for one mold to produce two pieces; design of a steel mold for casting T-joints made of aluminum which are inserted with 2 M10 steel bolts with a length of 15 mm before casting; preparation of polypropylene (PP) plastic material by adding 10% used PP plastic and giving pigment colors according to order; PP injection molding at a temperature of 160oC, duration of 12 minutes; order of a wooden handle from a professional wood craftsman; assembly of a plastic hammer with a T-shaped aluminum casting; trial beating on a rubber block for thread bond inspection; finishing; quality-dimensional inspection. The manufacturing results are in the form of a polypropylene plastic hammer with a total weight of T Aluminum and 2 plastic hammer heads of 300 g (without wooden handles), a total length of 30 cm, an oval diameter of 5x4 cm, a manufacturing cost of IDR 70,000/unit and a manufacturing duration of 12 minutes/unit which has the consequence that the 300 g plastic hammer can be used for hitting metal without damaging its surface, especially for small movements in adjusting components or workpieces during machining or assembly.

Abstract

This study presents a design for an IoT-based smart greenhouse system with automatic watering and web-based monitoring using the ESP32 microcontroller. The main issue addressed is manual plant watering that makes it difficult for users to monitor soil moisture, temperature, air humidity, and irrigation efficiency in real time. The system is designed using capacitive soil moisture sensors, DHT11, 1-channel relays, 12 V DC pump, and a web dashboard application based on React with chart.js for remote monitoring and control. The method used is Research and Development (R&D) with a prototyping approach, as the study focuses on designing, building, integrating, and testing IoT devices through iterative stages. Sensor data is transmitted to a Node.js backend server in the form of percentages and plant condition status, while the pump can be controlled via the web dashboard or hysteresis-based automatic mode (35-45% soil moisture). The system is equipped with a 120-item local buffer for offline resilience and automatic database archiving every hour for data storage efficiency. Intelligent irrigation algorithms use VPD (Vapor Pressure Deficit) computation and trend analysis to provide optimal watering recommendations. The system has been designed with a modular architecture that allows scalability and integration of additional sensors.

Abstract

This study aims to analyze the risk of failure in the bakpia production process in the Micro, Small, and Medium Enterprises (MSMEs) sector using the Failure Mode and Effect Analysis (FMEA) method. The research is motivated by inconsistencies in product quality due to unstandardized production processes, limited resources, the use of simple equipment, and weak quality control. The research method used is a descriptive qualitative approach with data collection through observation, interviews, and documentation. Each production stage is analyzed to identify potential failures, their causes, and their impact on product quality. Risk assessment is carried out based on severity, occurrence, and detection parameters to obtain a Risk Priority Number (RPN) value. The results show that several production stages have dominant failure risks that affect product quality. The FMEA method has proven effective in determining risk priorities and serves as a basis for developing improvement proposals to minimize product defects and improve the quality and efficiency of the production process in a sustainable manner.
