Abstract

Men who have sex with men (MSM) are the most vulnerable key population in the transmission of HIV AIDS. They have closed behavior that makes it difficult for health programs to reach. This study explores the structural dimensions of MSM with HIV in preventing HIV AIDS transmission from the perspective of social networks and associations among MSM with HIV. This qualitative study with a grounded theory approach was conducted in Jember. Data were collected by using in-depth interviews with 12 HIV-positive MSM. Data were analyzed with the stages of codes, categorizing, and basic social-psychological processes. The triangulation is used to obtain the validity of the information. Being an MSM group for a long time, related to social networks and associations. The social network perspective is built through gathering activities with fellow MSM communities, gathering in cafes, boarding houses, own homes, rented houses, town square, and night entertainment places. Providing health information, safe sex, asking for HIV tests, and monitoring ARV is more manageable through the same HIV-positive MSM. The involvement of HIV-positive MSM in social activities or other environments can reduce the stigma and discrimination. From the association's perspective, to facilitate the socialization of HIV AIDS prevention are carried out through social activities. A few HIV-positive MSM use herbal medicine and do not believe in ARV. Regular peer group support activities can provide a correct understanding of the importance of ARV to minimize the risk of loss to follow-up. Elements of social networks and associations through peer group supports involved in social activities can facilitate communication, information, and education; also, controlling sexual behavior prevents HIV AIDS transmission. The policymakers need to strengthen community-based associations.

Abstract

The COVID-19 pandemic has occurred since 2020 and since the appearance of the first case, Indonesia has experienced three peaks of COVID-19 attacks. The elderly are one of the vulnerable groups with high mortality due to comorbidities. Implementation of health protocols is the key to controlling the incidence of COVID-19. The purpose of this study was to analyze the differences in the implementation of health protocols for the elderly living in urban and rural areas. This is a correlational study with a cross-sectional approach. This study involved 447 elderly living in urban and rural areas who were taken by purposive sampling technique. The data was taken using a questionnaire instrument and the analysis was carried out using the Mann Whitney test using SPSS 21 for windows. The results showed that of the 235 elderly living in urban areas, 52.3% of respondents showed compliance with health protocols and of 212 respondents who lived in rural areas, only 15% of elderly people complied with health protocols. The results by Mann Whitney analysis showed p-value of 0.000 smaller than α 0.05 so it was concluded that there was a difference in compliance to the implementation of health protocols between the elderly in rural and urban areas. People in rural areas, especially the elderly, still do not believe in COVID-19. So it is necessary to do health education with an approach that is in line with their value, for example, with a cultural approach.

Abstract

Brake lining is a component that has the function of slowing or stopping the speed of a vehicle. Brake linings sold on the market are generally made from asbestos which is not friendly to health and the environment. Therefore, there is a need for alternative ways of making brake linings with materials that are safe for health and the environment, one of which is by using sugarcane bagasse waste, seeing that the nature of sugarcane bagasse is fibrous so it has the potential to be used as an alternative material for brake lining mixtures. The aim of this research is to analyze the best hardness and wear of composite brake pads made of bagasse material and iron powder as reinforcement with an epoxy matrix through the Shore D hardness test and Oghosi wear test, with the composition of bagasse ranging from 35%, 40%, 45% varying with iron powder of 15%, 10%, 5% and mixed with 50% epoxy resin with the same content. Shore D hardness test results obtained the highest hardness, namely at a volume fraction of 35%: 15%: 50% with a value of 72.5 HD. In the Oghosi wear test results, the lowest wear was in the volume fraction of 35% : 15% : 50% with a wear value of 0.000203 Ws;mm 3 /kg.m. The results of this research show that the large percentage of bagasse and iron powder mixed will affect the hardness and wear values of the brake pads.

Abstract

The Tahfidzul Qur'an Bambu Kuning girls' dormitory is an Islamic boarding school-based educational foundation located in Tanggul Kulon Village, Tanggul District, Jember Regency. The maximum number of dormitory residents uses calculations of the space capacity in the building and the development plan for the Islamic boarding school. Based on this approach, the maximum number of boarding school residents is 320 people. So if the occupants meet the maximum capacity, the waste that will be produced is 61.44 m3/day. The handling of domestic waste (blackwater and greywater) at the Tahfidzul Qur'an Bambu Kuning girls' dormitory is still processed using a septic tank which directly absorbs into the ground and there has been no draining activity so far. This has the potential for environmental pollution, which causes the potential to increase. suffer from disease. Therefore, it is necessary to make efforts to improve sanitation, namely planning a domestic wastewater treatment plant with an Anaerobic Baffled Reactor (ABR). The planned ABR has 3 compartments with total dimensions of length, width and depth of 12.3 meters, 6.12 meters and 2.5 meters. Construction with the ABR unit produces low concentrations of BOD, COD, TSS, oil and fat, and total coliform, respectively 6.82 mg/L, 17.5 mg/L, 7.87 mg/L, 1.46 mg/ L, and 300 mg/L which meets the quality standards set by the Minister of Environment and Forestry Regulation No. 68 of 2016 concerning domestic wastewater quality.
