ABSTRACT Each welding process has its own advantages depending on the placement of the implementation. One of the welding techniques is SMAW (Shielded Metal Arc Welding), which has its own advantages, including large currents such as heat source that can be varied, easy to use in different welding positions and penetration and the melting height of the electrode can be adjusted. In the SMAW …
ABSTRACT Planning a good residential house will greatly support the process of implementing development so that the building can be realized with satisfactory conditions. The product of planning is in the form of a drawing plan. In planning, it is also important to consider the important factors in planning a residence, including: comfort factors, health factors, structural factors and affor…
Abstract The use of sunlight has been widely done to winI need either directly or through a higher process One of them is to turn the solar energy into a DC power a the arrangement of solar cells as a solar energy modifier into electrical energy. Voltage regulator serves to provide a fixed DC output voltage that is not influenced by input voltage changes, output load current, and temperature. …
ABSTRACT Catfish is the most common type of livestock fish encountered. Following current developments, the level human mobility is increasing the ordinary catfish farmers feed manually. The dense activities of farmers that make fish often eat late because of limited time. This study, designed a fedder device on arduino uno based catfish, this tools can feed automatically on catfish every day.…
ABSTRACT Groundwater level in peatlands is very important to be maintained so that drought does not occur. Drought in peatlands can cause forest fires, especially during the dry season. The way to maintain ground water level is by canal blocking. The purpose of this study is to analyze groundwater flow in peatlands due to canal blocking. Groundwater velocity measurements are carried out on m…
Forest and peatland fires cause haze disasters that threaten aspects of human life at the local, national, regional and even global level. Loss of vegetation and the opening of peat swamp forests cause flooding in the rainy season, reduce carbon sequestration thereby increasing the greenhouse effect, and forests will lose their climate regulation function. The purpose of hydraulics modeling re…
Abstract The accuracy of catch production data is one important component in efforts to develop the captured fisheries sector. The accuracy of catch production data can be realized if the data collection is done well and in accordance with procedures in the compilation of data that has been determined. This study aims to determine the accuracy of production data on tuna catches and the facto…
Long segment preservation, combines routine maintenance works, widening, rehabilitation, and reconstruction of one continuous road segment into one single contract which is purposed to obtain steady road condition throughout the segment. This research is conducted to analyze the critical success of contractor’s performance in implementing this long segment preservation program. Contractors …
Reducing the risk of forest fires that have a negative impact, it is very important to study and improve the patterns and practices of forest resource management and communities living around the forest. The pattern and practice of forest resource management and the community around the forest must be formulated in a forest fire prevention strategy. This study aims to: (i) explore information o…
One of the most important components to prevent the occurrence of fires in Tropis peatland is groundwater level. Monitoring groundwater level directly in the field requires a high cost. Therefore is Background, this study will make Hydrological Model for Prediction of Groundwater Level in Tropis Peatland as Fire Mitigation Efforts based on rainfall data and groundwater level data. This reseac…
The availability of wood with suitable properties for bridge construction has become increasingly scarce. The reason is the decreasing size of the forest as a source of timber. To anticipate this, innovation is needed by utilizing wood which is still widely available but does not meet the requirements. In this regard, the purpose of this study is to examine the behavior of merau wood and wood c…
The availability of water in the Sub DAS Kampar Kanan which has an important role in addition to being a catch for the Kampar river as well as where the PLTA Koto Panjang hydropower reservoir is located. The hydrological model to be used is the GR4J Model (Genie Rural a 4 parametres Journalier) developed by Perrin, and IHACRES model developed at Australian National University (ANU). The GR4J mo…
This study is intended to analyze the steel frame construction if the work is done in stages. Birandang Bridge is chosen as an example, one of the steel frame bridges in Riau Province with a span of 140 m.
