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 Bay leaf tea is a herbal drink that has many benefits for human health as an anti-virus, anti-oxidant and can reduce symptoms of hypertension and gout. This study aims to study the effect of temperature variations and drying time in producing simple drugs and to analyze the tea content of bay leaves and compare it with the SNI standard No. 01-3143- 2011. The method used is drying …
ABSTRACT Oyster mushroom baglog waste that is not utilized properly will cause problems such as environmental pollution and can also be a source of pollution for cultivated oyster mushrooms. Making biobriquettes from mushroom baglog waste is an alternative for managing oyster mushroom baglog waste. However, the briquettes produced must also be of good quality, the quality of biobriquettes …
ABSTRACT The rapid development of industry has contributed greatly to economic growth, but has also had a negative impact on the environment, especially in the form of water pollution due to industrial wastewater. One of the common pollutants is methylene blue dye, which is widely used in the textile industry. This substance is toxic, difficult to degrade, and can cause disruption to aquatic e…

ABSTRACT Biomass is a fuel that can be used directly or processed first into solid, liquid or gas fuel through a certain process. Liquid smoke produced from the torrefaction process is a condensation liquid that comes from heating biomass without oxygen. The clarification of liquid smoke used as a food preservative must be carried out through a distillation and adsorption process first. The ob…
