ABSTRACT Erosion and sedimentation can reduce the capacity of waterways, so to overcome the problem of sedimentation in irrigation canals, a mud interceptor building is needed. Therefore, in this research, a sandtrap dimension planning is planned. This research aims to design an effective and efficient santrap design in accordance with the existing conditions in the Sei Tibun Dam irrigation ne…
ABSTRACT This study aims to analyze the productivity of heavy equipment in embankment and granular pavement work on Jalan Kampus Universitas Riau. In the construction of road infrastructure, the efficiency and effectiveness of heavy equipment use greatly affect the implementation time and cost of the project. This study compares two alternatives for the use of heavy equipment: the equipment us…
ABSTRACT Excessive use of groundwater will have an impact on reducing groundwater levels. To overcome this, implementing environmentally friendly drainage is one solution to prevent shallowing of groundwater levels. At Annajim Housing, changes in land use will increase surface runoff and reduce water infiltration into the ground, thereby potentially causing flooding and decreasing environmenta…
ABSTRACT Concrete is one of the main construction materials widely used in infrastructure development due to its high compressive strength and good durability. However, achieving optimal compressive strength typically requires a relatively long curing period, approximately 28 days. To address this limitation, admixtures such as Bestmittel are used to accelerate the hardening process and improv…
ABSTRAK In the implementation of excavation work on the Revitalization of Lake Bakuok project in Kampar Regency, heavy equipment assistance is needed to facilitate the work process, one of which is in excavation and soil transportation. The gradual or relay excavation method causes problems such as high equipment efficiency and fuel consumption so that operational costs increase and the du…
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…
