Abstract

One of the efforts to prevent the transmission of Covid 19 is washing hands. Washing hands is one of the sanitation efforts by cleaning hands and fingers using water and soap or handrub by humans to be clean and break the chain of germs. Hands are often the agents that carry germs and cause pathogens to pass from one person to another, either by direct contact or indirect contact. Therefore, seeing the urgency of washing hands in an effort to prevent the transmission of Covid 19, we provide assistance to implement hand washing in public facilities where contact between humans often occurs. The service was carried out on October 3, 2020 at the Balang-Balang market, Borong Loe Village, Bonto Marannu District, Gowa Regency. The head of the Borong loe village received hand washing machine assistance. In addition to hand washing machine assistance, information is also displayed regarding proper hand washing steps and information about the spread of covid 19

Abstract

Porang is a tuber plant with the Latin name Amorphophallus Muelleri. In some areas of South Sulawesi, this plant is known as Tire. Porang belong to the family Araceae, which is a type of tuber plant that is able to live in various types and soil conditions. Porang plants do not have to get direct sunlight so these plants are easy to find on the sidelines of forest plants, plantations or populated land. The main problem faced by the community of bonti village is that They cannot process porang into flour due to lack of flouring machine and does not have human resources that can operate machines / make flour porang. Based on this problems, We do a community service by applying science and technology in bonti village in the form of technology machines that can turn porang into flour. The flouring mechine used is an FFC-15 type with 3 filters driven by a YC90S-4 Single-phase electric motor of 0.75 kW 1 HP with a maximum rotation of 1400 rpm. The machine and electric motor are connected by a v-belt and pulley on both shafts. The result obtained is an increase in the ability to produce flour reaching 80-100kg per hour according to the level of dryness of people's chips. The economic impact felt by partners is the occurrence of savings in production when using electric motors. Per hour of operation of an electric motor only requires around Rp.1,500 which saves up to 80% compared to the use of gasoline or diesel engines.

Abstract

This research to determine the effect of the tensile load on the carburizing process and the heating temperature lower than the normal carburizing temperature on the hardness of carbon steel with a percentage of 80% buffalo bone charcoal and 20% BaCO3, 20 mesh grain size, 4 hours holding time, and slow cooling with a tensile load of 1/4σp 1/2σp 3/4σp, and σp (proportional stress). The heating temperatures below normal carburizing temperatures, namely 6000C, 6500C, 7000C, and 7500C while being pulled by 1/4σp, 1/2σp, 3/4σp, and σp. After reaching the heating temperature, the material is held in the furnace for 4 hours and cooled slowly. After the material is cold, mechanical testing is carried out with Vickers microhardness. Hardness value at a temperature of 6000C is 103.93 HRB, at a temperature of 6500C is 104.33 HRB, at a temperature of 7000C is 104.80 HRB, and at a temperature of 7500C is 106.60 HRB, while the process of pack carburizing without tensile at a heating temperature of 8000C is 105.2 HRB. This proves that the application of loads at lower heating temperatures during the heating process can exceed the hardness value without tensile loads at higher temperatures of 8000 C.

Abstract

Likuifaksi adalah suatu fenomena kehilangan kekuatan geser tanah pada lapisan jenuh air akibat gempa bumi, sehingga tanah mengalami keruntuhan  dan berperilaku seperti (liquid). Likuifaksi umumnya terjadi pada tanah non kohesif (glanuler) jenuh air dan menerima beban siklik berupa gempa. Dalam penelitian ini, simulasi getaran yang mengakibatkan liquifaksi menggunakan alat bantu berupa shaking table dengan mekanisme gerak hidrolik, sinyal input yang diberikan berupa sinyal sinusoidal dengan variasi tekanan oli hidrolik 0 bar, 6,25 bar, 12,5 bar, 18,75 bar, 25 bar, 31,25 bar,37,5 bar, 43,75 bar dan 50 bar. Hasil penelitian menunjukkan bahwa Semakin kecil nilai tekanan bar oli hidrolik yang diberikan maka akan semakin kecil juga nilai MR yang didapat. Ini dikarenakan daya dorong yang diberikan tekanan bar berpengaruh kegerak lengan piston hidrolik, semankin tinggi tekanan hidrolik yang diberikan maka akan semakin cepat gerak lengan piston hidrolik, dan semakin cepat gerak lengan piston hidrolik maka semakin besar juga nilai percepatan terhadap sumbu x dan sumbu y. Dan Inputan sinyal sinusoidal yang bisa digunakan untuk eksperimen potensial liquifaksi yaitu sebesar 6,25 bar, 12,5 bar, 18,75 bar, 25 bar, 31,25 bar, 37,5 bar, 43,75 bar, dan 50 bar. Dikarenakan nilai yang dihasilkan variasi tekanan oli hidrolik tersebut masuk range syarat terjadi liquifaksi yaitu sebesar 5 – 7 SK.

Abstract

Pada tulisan ini, penerapan CNC laser cutting dalam pemotongan memiliki beberapa kriteria hasil potong yang perlu di identifikasi. Pemotongan dengan menggunakan CNC laser cutting adalah metode nonkonvensional dengan menggunakan perangkat komputer sebagai alat untuk menjalankan perintah numerik dengan koneksi usb pada mesin. Sehingga, dapat melakukan pemotongan sesuai dengan pola CAD yang telah dibuat. Hasil potong yang diidentifikasi pada material kain tekstil ini yaitu pengaruh kecepatan 100 mm/min, 150/mm/min, dan 200 mm/min, dan penggunaan daya laser yaitu 2.5, 3.5, 4.5, 5.5 watt terhadap kerf width (mm), SLL (mm), dan Diameter Circle (mm), serta MRR (mm) pada jarak laser head 60 mm. Hasil pengamatan menunjukkan semakin kecil penggunaan daya dan semakin tinggi tingkat kecepatan pemotongan akan menghasilkan kerf width yang lebih kecil. Sehingga, dapat disimpulkan bahwa faktor interaksi kecepatan pemakanan dan penggunaan daya merupakan parameter yang paling berpengaruh terhadap hasil pemotongan bahan kain dengan jarak fokus laser 60 mm.
