ABSTRACT Abstract: This research is motivated by existence a need for users every year for home internet to expand the coverage area of the network. PT Icon+ comes with plans to collect data related to homepass, and expand the network by adding Point Of Presence in the southern Sumatra area in areas not yet covered by the PT Icon+ network and also to meet the 2021 marketing target for the reta…
ABSTRACT The powder mixing/blending process plays an important role in powder metallurgy because the uniformity of the powder mixture greatly affects the quality of the resulting product. The aim of this final project is to make a metal powder mixer that can be used for powder metallurgy processes. Mixing speed on this machine is controlled using a 12V 110 rpm DC motor. The working principle o…

ABSTRACT The process of filtering soybean pulp to separate tofu water and dregs in the tofu-making home industry is still carried out in a traditional and less efficient way. Though this process affects the taste, quality and quantity of tofu produced. Need to apply simple technology in the screening process. Centrifugal filtering can be applied to separate soybean pulp and dregs using the cen…

ABSTRACT A DC-AC converter (inverter) is one of the electronic devices used to convert DC voltage (direct current) to AC voltage (alternating current). The output of the DC-AC converter can be an AC voltage with sine wave, square wave, and quasi-square wave forms. The DC-AC converter really functions as a backup power provider, providing emergency power when the power goes out. In addition, in…
ABSTRACT In an effort to manage water quality, the construction of water structures must be appropriate in order to maintain water quality and quantity. In the planning of water structures begins with hydrological analysis. To obtain accurate hydrological data, it is necessary to have a sufficient number of rain gauge station that are evenly distributed so that they can represent the hydrologi…
ABSTRACT Gate valve is a machine element that is commonly used to control the flow of fluid and gas at high pressure, so that in the process of making a gate valve it is necessary to pay attention to design characteristics. This study aims to obtain a gate valve design using the Quality Function Deployment (QFD) method. Data was collected by distributing questionnaires and conducting interview…
ABSTRACT In the case study at UKM, Wardi Tahu still uses a 25 kg paint bucket filled with water as the weight. This study aims to design a pneumatic system tofu pressing machine using the quality function deployment (QFD) method and obtain the design characteristics of a pneumatic system tofu pressing machine as desired by UKM Wardi Tahu. In the design of the pneumatic system tofu pressing…
ABSTRACT Indonesia uses an average of 9.8 billion plastic bags annually, and 95% of the plastic bags used become waste. One of the methods to utilize plastic bag waste is as a material for paving block production. This research sought to explore the potential of High-Density Polyethylene plastic bag waste as material for paving block production. The paving block that will be made is a mixture …
ABSTRACT Domestic demand for calcium chloride continues to increase every year. Calcium chloride is a chemical substances needed by industries such as the pulp, cement and food preservative industries. Calcium carbonate can be processed into calcium chloride through the acidification process. The main raw materials used in the manufacture of calcium chloride by acidification process are calciu…
ABSTRACT Dimethyl phthalate is a type of plasticizer that is widely used for the manufacture of nitrocellulose and cellulose acetate rubber. Dimethyl phosphate as a plasticizer is also used as an additive to make plastic products. The need for imports of dimethyl phthalate in Indonesia has tended to increase in the last five years. Dimethyl phthalate production plants are still minimally e…
ABSTRACT Potassium phosphate (KH2PO4) is one of the inorganic fertilizers whose production locally is still small. This fertilizer consists of the main components of potassium and phosphate where these elements are macronutrients needed by plants. The need for imports of potassium phosphate in Indonesia has tended to increase in the last five years. Potassium phosphate production plants ar…

ABSTRACT One of the chemical industry which has important uses and has good prospects is the butanediol industry. Butanediol with the molecular formula C4H10O2 are hygroscopic liquid that is colorless and almost odorless. Butanediol (BDO) is an important element in a long production chain consisting of various intermediates and their derivatives, which are used in a wide range of industries an…
ABSTRACT Acetone (CH3COCH3) also known as 2-propanone or dimethyl ketone is a very important ketone derivative. This chemical is widely used as a solvent, because acetone is a good solvent for various gums, waxes, resins, fats, oils, dyes, and cellulose. Until now, no company has produced acetone in Indonesia either as a side product or as a main product. At this plant, acetone is made thr…
ABSTRACT One of the basics of building planning is drawing planning and the calculation of the Budget Plan (RAB). Plan drawings are needed to calculate RAB and also as a guide when carrying out work in the field. This RAB aims to be able to find out the details of the costs incurred by the building owner when constructing the desired building. The RAB calculation requires a reference in the fo…
