Abstract

Public services are interactions between society and the government as public servants. This service activity involved the Pinrang Regency Investment and Integrated Service Agency (DPMPTS) and academics from the Mechanical Department, Faculty of Engineering, Hasanuddin University. Utilizing this disinfectant tool can help the DPMPTS service in terms of air sterilization and preventing the spread of Covid-19 in community service spaces. The problem that arises is the level of interaction between the community who needs services and DPMPTS employees as service providers who are quite vulnerable to the spread of viruses and bacteria. This can cause the spread of disease, so tools are needed that can reduce the impact of the spread of the disease. The use of Ultraviolet C (UVC) is a disinfectant tool that has been proven effective in killing microorganisms, one of which is the COVID-19 virus. The service method is carried out using an outreach mechanism at the DPMPTS agency which is attended by technical government agencies and several participating local communities. The process of implementing socialization uses a questionnaire mechanism consisting of pre-test and post-test. At the start of the socialization, the number of respondents who filled out the questionnaire was 18 people consisting of 8 government representatives and 10 community representatives or a total of 18 respondents. In the pre-test results, it was found that only 3 people understood the function of the mobile robot disinfectant system mechanism and 15 people did not understand. After the socialization was carried out, better results were obtained with 17 people who understood and 1 person who still did not understand the working system of the mobile disinfectant robot. Therefore, it is recommended to use mobile disinfectant robots in DPMPTS public service spaces to reduce the effects of spreading viruses and bacteria.

Abstract

Pada suatu sistem perpipaan kerugian aliran (head losses) selalu terjadi. Kerugian aliran yang terjadi dalam pipa menyebabkan terjadinya pengurangan debit aliran. Hal ini, disebabkan karena beberapa faktor diantaranya adalah kekasaran permukaan dinding pipa dan akibat adanya sambungan (fittings) pipa. Kekasaran permukaan dari dinding pipa tergantung dari jenis-jenis pipa yang digunakan, seperti pada pipa galvanis dan PVC keduanya memiliki nilai kekasaran permukaan yang berbeda, dimana pipa galvanis memiliki nilai kekasaran permukaan yang lebih besar. Pada pipa PVC dengan debit aliran 0,00027 m3/s menghasilkan total head losses terkecil bernilai 0,2438 m pada metode Hazen-Williams kemudian pada debit aliran 0,00047 m3/s  menghasilkan total head losses terbesar bernilai 1,4285 m pada metode Darcy-Weisbach. Pada pipa Galvanis dengan debit aliran 0,00027 m3/s menghasilkan total head losses terkecil bernilai 0,2623 m pada metode Hazen-Williams kemudian pada debit aliran 0,00047 m3/s  menghasilkan total head losses terbesar bernilai 2,4100 m pada metode Darcy-Weisbach. Sehingga hubungan antara debit aliran dengan kerugian aliran berbanding lurus dan kekasaran permukaan juga berbanding lurus dengan kerugian aliran. Kerugian aliran terbesar ada pada pipa Galvanis dengan debit aliran 0,00047 m3/s dan total head losses 2,4100 m di metode Darcy-Weisbach. Kerugian aliran terkecil ada pada pipa PVC dengan debit aliran 0,00027 m3/s dan total head losses 0,2623 m di metode Hazen-Williams.
