Abstract

The Ministry of Tourism and Creative Economy again held a Tourism Village Community Empowerment Program. The collaboration between the Ministry of Tourism and Creative Economy, the Ministry of Villages for Disadvantaged Regions, and Transmigration and Higher Education is one of its forms. Higher education institutions are required to carry out community service programs. One of these activities is in the form of human resource development activities involved in the management of tourism villages, namely Pokdarwis (Tourism Awareness Group). One of the human resource developments carried out is the strengthening of CHSE (Clean, Health, Safety, and Environmental Sustainability) materials. CHSE is a new program that is being socialized by the Ministry of Tourism and Creative Economy to encourage healthy and safe tourism activities in all tourism destinations. Also, with the existence of correct and adequate CHSE and health protocols, it becomes one of the attractions for tourists to visit tourist villages. This activity was attended by 25 participants from Pokdarwis (Tourism Awareness Group), Sungai Awan Kiri Tourism Village, Ketapang, West Kalimantan. This activity aims to improve the competence of human resources for managing the Sungai Awan Kiri Tourism Village which is closely related to CHSE, K3, and the implementation of health protocols that must be implemented in the New Normal era in tourist villages.

Abstract

Learning media plays an essential role in conveying material to students. Learning media can be divided into media that Teacher directly use in learning and media made by Teacher that later adapted to the abilities and needs of students. Engineering mechanics is one of the primary subjects that civil engineering students must master at. The engineering mechanics course discusses the analysis of the balance of a structure. Students can use mobile application-based teaching materials as online learning media amid the COVID-19 pandemic. Engineering mechanics book, we called EMB, can be used by students to study independently at home during learning online but still in the monitoring/monitoring of Teacher (lecturers). The research and development use ADDIE design. The stage includes 1) Analysis, 2) Design, 3) Develop, 4) Implementation, and 5) Evaluation. EMB product had been tested the validity and implementation during the learning process. EMB got 3.32 valid results for the product. EMB can also train students in digital literacy. Students' digital literacy is in the quite proficient category. This condition is not regardless of the influence of student habits in using technology which is more often used for online communication and entertainment. The frequency of using digital technology for entertainment purposes is higher compared to use for academic purposes.

Abstract

The need for low carbon steel plate sheets with relatively thin thickness measurements in Indonesia is currently quite high, especially in supporting the automotive industry, the electronics industry, the food industry, beverages, and household appliances. To fulfill this, raw materials for low carbon steel plate sheets that have high formability and are not easily cracked in critical areas of the desired model are required. For this reason, research on the effect of temperature variations in heat treatment on hardness, microstructure and spring back of V-bending results on steel plates with a plate thickness of 0.8 mm. The research method used was a laboratory experimental method. The heat treatment is carried out with temperature variations of 710, 820 and 9300C with a holding time of 60 minutes. Tests carried out on specimens are hardness testing, microstructure testing, and spring back V-bending results on steel plates. The results of this study indicate a decrease in the spring back angle where the smallest spring back angle in the bending process is on the 9300C plate which is 1,040. The value of the hardness results from V-bending has increased significantly. The increase in the value of hardness because the plate has an atom shift or dislocation by shear stress (slip) due to plastic deformation on the plate. The highest hardness value is on the 7100C plate which is 154.67 HV or has an increase of 14,291% of the pre-bending plate. The lowest hardness value is on the 9300C plate which is 125.33 HV, its hardness increases 4.4% against the pre-bending plate. Heat treatment also causes changes in the microstructure of the plates from the process of regulation and reshaping of crystals to the growth of new grains which have implications for changes in mechanical properties and formability of the workpiece.

Abstract

Metal connection due to heat with or without the influence of pressure or metallurgical bonds caused by attractive forces between atoms. DIN (Deutsche Industrie Normen) state that metallurgical bonding of metal or guide metal joints in a melted or liquid state. This study aims to determine the effect of limestone powder and gypsum as an insulating medium in SMAW (Shielded metal arc welding) welding. This study using experimental methods with SMAW welding. Welding metal cooled with limestone media has a harder hardness than gypsum and air media, which is limestone has a thermal conductivity value of 3.897 W / mºC. In comparison, gypsum has a thermal conductivity value of 1.39 W/mºC, and air has a thermal conductivity value of 0.023 J/msºC, so limestone is a better insulator than gypsum and air. The greater the conductivity value of the object, the better the thermal conductivity of the metal and the more complicated the weld metal and the lower the thermal conductivity value, the softer the metal hardness, limestone has a thermal conductivity value of 3.897 W / mºC while gypsum has a thermal conductivity value of 1, 39 W / mºC and air have a thermal conductivity value of 0.023 J / msºC, proving that the lower the conductivity value, the hardness of the weld metal is getting softer, but in the HAZ section it proves that the lower the conductivity value, the more complex the hardness in the HAZ section.

Abstract

Strength, toughness, machinability and damping capacity are properties of compacted graphite iron that distinguish the properties between flake graphite cast iron and spheroidal cast iron. The formation of compacted graphite can be set to achieve the required specification. The formation of compacted graphite is started from spheroidal to compacted cast iron. The residual magnesium after magnesium treatment and the solidification rate have a significant role in the formation of compacted graphite. The high content of residual magnesium can obstruct the graphite plane to grow during the transformation from spheroidal to compacted shape. In addition, the cooling rate of the casting can be controlled by varying the casting thickness. The compacted graphite in the cast iron are characterized according to shape, size and distribution. The optimum compacted graphite in the cast iron that can be produced has 30 mm of casting thickness with 0.017 % of residual magnesium.

Abstract

Sand is an important material in building construction for residential houses, places of worship, offices, educational facilities, and other buildings. Sand generally consists of sand mixed with gravel and stone. An automatic sand sieving machine makes separating rock gravel from sand easier. Making an automatic sand sieving machine aims to get better quality and cleaner sand screening results. This sand sifter machine is made to prevent the entry of gravel in the sieving process. In addition, the sand sieving process can be more efficient and effective. The automatic sand sieving machine has dimensions of 100 cm long, 70 cm wide, and 80 cm high. The test results of the sand sieving machine can sift sand with a capacity of 5 kg in 15 seconds and a sand capacity of 10 kg in 32 seconds.
