ABSTRACT The vacuum freeze-drying method is one of the best drying processes for food preservation because it is able to remove moisture without compromising its quality. One type of fruit that has a low selling value is yam because the usage of yam is still limited and it has several weaknesses, including poor durability of fresh yam which is ± 5 days, easiness to spoil because it contai…
Washing is a routine that everyone does. Therefore the business opportunity for such activities is needed. Many townspeople barely have time to wash their own clothes. As a result, laundry services are increasingly needed. Drying is a process of discharging water contained in a dried material. In the drying process it is necessary to have a dry air fluid capable of absorbing water in the materi…
ABSTRACT The vaccination program is targeted to last until March 2022. Based on vaccination targets, the Vaccine that is widely used is a Vaccine with a distribution temperature of 2-8 °C of 276.5 million. The thing that really needs to be observed is how to distribute the covid-19 Vaccine from one place to another that is able to keep the temperature so that the Vaccine can be maintained…
ABSTRACT Secretary General of the Ministry of Health (Kemenkes) Oscar Primadi stated that the obstacle in distributing the covid-19 vaccine in Indonesia is that there are still many remote areas that are difficult to access by vehicles that have cooling rooms such as planes, ships or box cars equipped with refrigeration boxes. In this study discussed about the design of vaccine carrier box…
ABSTRACT In this research carried out innovation in wind turbine that generate power using wind energy. Where the propeller wind turbine and the venturi wind turbine are combined into one axis. The purpose of this study was to determine the additional performance of the propeller wind turbine after combining it with the Venturi wind turbine at low wind speeds. The performance of this hybri…
ABSTRACT Organic pots from oil palm tankos fiber are products that have a high selling value, and are environmentally friendly that can maintain soil moisture (mulch). To produce organic pots, a hot press pot molding machine is needed which consists of the main components, namely a hydraulic press machine, pot mould, heater, temperature control, panel box. The manufacture of pot molds begi…
ABSTRACT Unmanned Aerial Vehicle (UAV) Serindit V-2 has entered the 2nd generation development stage. The vehicle is designed to take part in the Indonesian Flying Robot Contest (KRTI) in the Airplane category, where the vehicle is designed to fly at high speed and maneuver. This study aims to determine the performance of the propulsion system and the flight performance of the Serindit V-2…
ABSTRACT Energy is a necessity for humans. One of the energies that we encounter a lot is heat energy. Solar radiation heat energy is the most abundant energy that propagates throughout the earth's surface and is absorbed or stored in various objects on the earth's surface. In this study, the use of solar energy stored on the asphalt surface of concrete and asphalt roads to be converted in…

Disc on Disc type Tribology is a type of tribology test instrument which is used to determine the quantity of tribology, of friction, lubrication and volume of wear. The working principle of Disc on Disc is the relative motion between materials in the form of disc that rotate each other so that friction occurs between the disc at a certain speed. This tribology aims to determine the wear an…

ABSTRACT Selais Indrapura is a prototype ship designed by the Riau University team. Using a mono hull type hull, this Indrapura was made to take part in the 2020 National Unmanned Fast Boat Contest (KKCTBN) which was held by the Directorate General of Learning and Student Affairs and the Ministry of Tekdikti of the Republic of Indonesia in collaboration with the University of Muhammadiyah …
ABSTRACT At this time, research on new materials is growing, one of which is experiencing a fairly rapid development in the field of composites. Researchers have also started moving from synthetic fibers to natural cereals. Apart from having quite good mechanical properties, natural fibers are also easy to obtain, especially in Riau, the fiber of Palm Oil Empty Fruits Bunches (EFB) is very eas…
ABSTRACT The Adyatma Urban energy-efficient car is one of the works of the Riau University Mechanical Engineering team. This car has been designed and built in 2020 to be included in the 2020 Energy Efficient Car Contest (KMHE). At the Energy Efficient Car Contest (KMHE), incidents often occur in the form of a vehicle rolling over when turning. This can happen because the level of security of …
ABSTRACT In everyday life, humans are very dependent on hot water, ranging from household needs such as washing dishes, washing clothes to bathing. Lately, hot baths have become a lifestyle for Indonesian people because there are so many benefits that can be obtained by taking a warm bath. One solution that emerged was the manufacture of direct expansion heat pump water heaters. The test was c…
ABSTRACT The abundance of solar energy received can be utilized as a source of renewable energy. The potential of solar energy in Indonesia reaches an average of 5.67 kWh/m2/day. The potential for solar energy is more than 400,000 MW and only about 10,000 MW has been utilized or about 3% of the existing energy potential. It is necessary to develop further regarding the use of solar energy usin…
