ABSTRACT Earthquake-resistant reinforced concrete structures must pay attention to the beam-column connection area because beam-column connection is a critical area that needs to be designed really accurately so that it can reduce the energy caused during an earthquake. The beam-column connection is designed to be able to deform during earthquake shocks so as to minimize damage, especially…
ABSTRACT The design of the steel structure must be designed in such a way according to SNI 1729 2020 so that it can withstand the load or force acting on the structure. The update of SNI 1729 2020 to SNI 1729 2015 resulted in differences in the design of beams and columns for steel structures. This study aims to analyze the design comparison of beams and columns of steel structures and identif…
ABSTRACT Geographically, Indonesia is located on the equator which has two seasons, namely the rain season and the dry season. In the dry season, the sun's heat is needed for various needs, one of these is to drying wet clothes. The drying process cannot be monitored directly. Therefore, an automatic clothesline system was designed. This design uses Arduino Uno as a microcontroller. Light …
ABSTRACT The development of renewable and environmentally friendly alternative energy needs to be carried out in order to fulfill energy needs and the survival of plants, animals and humans. One of the energy sources that can be used to meet these needs is solar energy. In solar panels, the heat generated from solar radiation is utilized through photovoltaic to generate electricity. Unfortunat…
ABSTRACT UAV is a technology of aerial vehicle without a pilot occupied within the body. Serindit V-2 is a fixed wing UAV that was designed to fly and accelerate rapidly. Most of fixed wing UAV lands by belly landing method. The bottom part of the fuselage experience direct impact with landing runways, and resulting to high risk of fracture. Besides belly landing, fixed wings were commonly fou…

The Warehouse Management System design that has been implemented using the kanban barcode method consists of several processes, including: 1) Desig…
ABSTRACT Bolts are one of the machinery elements which are used in joining. The failure that often occurs in bolted joints is looseness caused by dynamics loads. This study aims to detect bolt looseness using sound signal by analyzing the dynamic characteristics of bolt connection, namely natural frequency, damping ratio and bolt looseness position. The research method which is used Structural…
ABSTRACT The isobutylene industry in Indonesia is one of the chemical industries that has good prospects. This isobutylene product has a wide market that is used as an intermediate compound and raw material such as MTBE (Methyl Tertiary Butyl Ether), ETBE (Ethyl Tertiary Butyl Ether), antioxidants, fragrance, lubricants, coatings. This final project aims to design an isobutylene plant that can…
ABSTRACT Indonesia has many needs which are still imported from other countries in very large quantities. One of the imported products itself is calcium chloride. Calcium chloride with the chemical formula CaCl2 is one type of salt consisting of the elements calcium (Ca) and chlorine (Cl2). To meet the availability of calcium chloride, Indonesia has to import from abroad due to the unavailabil…
ABSTRACT Glycerol is a raw material for the manufacture of acrylic acid which is obtained from one of the side products of crude palm oil processing. Acrylic acid is an intermediate that is widely used in acrylic ester and resin products which are then polymerized to become coating paints, textiles, adhesives, and plastics. The acrylic acid production process generally consists of 3 stages of …
ABSTRACT Diphenylamine is a byproduct of an aniline in which the amine is enhanced between two phenyl groups. Diphenylamine is used as a fixative for colors, a pharmaceutical ingredient, a product preservative in the agricultural industry, an explosive, and a smell in the beauty industry. The purpose of the establishment of diphenylamine is to produce diphenylamine to meet domestic diphenylami…
ABSTRACT Acrylonitrile Butadiene Styrene (ABS) is a copolymer styrene, acrylonitrile and polybutadiene. Acrylonitrile monomer is stable at -20oC to 100oC and resistant to corrosive chemicals, impact resistance and toughness properties of butadiene, combined with the rigidity of styrene, to obtain ABS properties, namely impact resistance and toughness. The addition of methyl methacrylate produc…
