Abstract

The Covid-19 pandemic has an impact on all levels of society in Indonesia, including coastal communities in the city of Semarang. This community service program is carried out to create hand washing tools without the need to turn the water tap to support a new lifestyle in the face of the Covid-19 pandemic, which is still a lot in the city of Semarang. Washing hands with soap is part of adapting a new habit after the Covid-19 pandemic hit the world. The method that we use is the manufacture of hand washing tools with a tread system by students of the marine construction engineering engineering technology study program at the Undip vocational school and hand over the equipment to the management of the Perpustakaan Pesisir Teratai 414 in Tambak Mulya, North Semarang District. The method used in this program is the design and manufacture of hand washing equipment with a stomp mechanism. The results of this program show that the community around the library is easier to move there without worrying about not being able to carry out the health protocol, which is to always wash their hands. With the implementation of this program, we can see that the need for the provision of hand washing equipment with a tread system is very high to face this critical period.

Abstract

Fishing boats have a construction design that generally uses wood materials. The cost of making fishing boats made of wood varies and the value depends on the type of construction design. The difficulty of recovering wood from this plant makes the need for alternative materials. HDPE plastic or polyethylene (PE) and polypropylene (PP) High Density Polyethylene (HDPE) which has good properties, such as corrosion resistance and light weight, is still one of the most widely adopted materials for the realization of an alternative construction. The purpose of this study was to determine and analyze the effect of temperature on pre heating on the HDPE plastic welding process. The method used is an experiment where the specimen is made using HDPE material according to the ASTM D638 standard. The welding process uses temperature variations between 4000 - 4500 C. The results show the highest value of tensile testing at pre heating 450o C is 18.2 MPa while the lowest value at pre heating 410o C is 13.7 MPa, with an average elongation of 136.8mm . This concludes that there is an effect of preheating on the plastic welding process with HDPE material.
