ABSTRACT Lemang is a traditional Indonesian food cooked by roasting glutinous rice in bamboo over an open fire. The manual roasting process requires a long duration and constant attention to ensure even cooking, often resulting in inefficiencies and uneven doneness. To address these issues, a closed-type rotary lemang roasting machine was designed and developed in this final project. The aim o…
ABSTRACT This research aims to design and develop a pesticide sprayer in the form of a trolley sprayer using a 2-stroke engine. This tool is designed to increase the efficiency of pesticide spraying in agricultural areas, especially in hard-to-reach locations. With a capacity of 70 liters, this trolley sprayer is expected to provide a wider spraying area than a hand-held sprayer with a manual …
ABSTRACT Coconut plants (Cocos nucifera L.) are multipurpose plants where all parts of the plant can be used to meet human needs. Coconuts have a strategic role in the national economy.In the process of peeling coconut skin, many still use manual methods and some also use coconut peeling machines. But there are still shortcomings in peeling young coconut skin. Therefore, a revision of the mech…
ABSTRACT Sand is an important material in the construction industry, but it often contains impurities such as gravel and clay that reduce its quality. Manual screening is still widely used, but this method is inefficient and requires a lot of labor. To overcome these obstacles, a sand screening machine with a rotating system was planned and manufactured that can increase the efficiency and qua…

ABSTRACT Infrastructure development, high-rise buildings, bridges, highways, toll roads, housing and so on require cement mixers (Molen). For small-scale construction such as casting house floors, terraces, bathrooms, cement mixing is usually done manually (using a hoe) which requires manpower/workers and a long time and increased costs for workers' wages. The use of a 25 kg type cement mixer …

ABSTRACT Sauce is a liquid or semi-liquid processed product commonly used as a complement to various types of food. Innovation in processing papaya-based sauce offers a promising alternative in the development of functional food products. However, most small and medium enterprises (SMEs) still produce sauce manually, resulting in low efficiency, inadequate hygiene standards, and high labor cos…

ABSTRACT This study aims to design and create a prototype of an automatic sliding roof utilizing a mechanism based on a rack and pinion gear, driven by a DC motor, and controlled by sensors and microcontrollers. The results of making the tool components: a fixed frame measuring 1750 mm long x 800 mm wide and 250 mm high, a sliding frame measuring 900 mm long x 800 mm wide, gear design, fiber r…
ABSTRACT The increasing amount of household organic waste requires an efficient solution in its management. One effort that can be made is to design a simple and easy-to-maintain household-scale organic waste shredder. The purpose of this design is to produce a shredder that is able to crush organic waste such as food scraps, leaves, and grass into smaller sizes so that it is easier for the co…

ABSTRACT The ripple mill mechine is a tool for breaking and separating palm kernels from their shells, in this mechine there is a rotor part that rotates on the ripple plate, the stationary part, the seeds enter between the rotor and the ripple plate so that they collide and break the shell from the core. The risk that is often experienced by the ripple mill machine is the occurrence of fallin…
ABSTRACT Pipes for electrical and telecommunication cable networks made of High Density Polyethylene (HDPE) composite materials reinforced with fiberglass in Pekanbaru are generally installed close to highways, some are on the ground surface, underground, or in water passing through the Siak River or other rivers. Pipes that are on the ground surface will get quite high heat intensity during t…
ABSTRACT This research aims to identify and calculate digester machine performance at PTPN V Sei Tapung based on Overall Equipment Effectiveness (OEE) values and analyze damage to digester machine components using the Failure Mode and Effect Analysis (FMEA) method. Overall Equipment Effectiveness (OEE) is a method of measuring the overall effectiveness of a production machine which involves me…
