Tourism is one of the sectors that has been seriously hit by the impact of the Covid-19 pandemic indicated by the sharp decrease in the number of both domestic and foreign tourists visit. The decrease has also been experienced by the popular tourist destination located in the border of Bondowoso and Banyuwangi Regency namely Ijen Geopark. Since the tourism sector has shown a significant role as a driver of economic activity, the aim of this work is to build public acceptance map toward Ijen Geopark as the government reduce the limitation of the prohibition policy to handle the spread of Covid-19. Sentiment analysis is adopted to build the public acceptance map by using TripAdvisor dataset. To gain a fine grained, results we extent the technique using our proposed aspect-based sentiment analysis making use cosine similarity algorithm and several keywords. Using several keywords and cosine similarity algorithm, we succesfully extract aspect of the topic. Employing Naïve Bayes, we then labeled the sentiment orientation of the associated aspect extracted from sentence. During 2022, we highlight the fact that most tourist positively accept Ijen Geopark. Some parts that need to be evaluated by the decision maker and related party is Sulfur Mining and the cost since both aspect received more negative comment compared to the positive ones.

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.

AbstractThis study discusses the improvement of the power factor in the Glenmore Sugar Industry electrical system. Low power factor can be caused by variations in inductive loads. This has an impact on large currents and high reactive power so that a black out can occur in the Glenmore Sugar Industry electrical system. Low power factor is corrected with the most effective Costum Power Devices, namely Static Var Compensator (SVC) and Static Synchronous Compensator (STATCOM). The evaluated and corrected load buses are those with low power factor.The simulation results show in the application of SVC for the lowest results, power factor increased from 0.76 to 0.78 with reactive power values in the range from + 1.6 to – 0.64 MVAR. The power factor increased from 0.76 to 0.85 with reactive power values in the range from +4.9 to –1.9 MVAR. And for the highest results, the power factor increased from 0.82 to 0.92 with reactive power values in the range from +3.9 to –1.5 MVAR.The application of STATCOM can increase the power factor with reactive power values in the range from +4.9 to – 0.994 MVAR, +1.6 to -0.32 MVAR and +3.9 to -0.7875 MVAR. Keywords – Power factor, SVC, STATCOM, Reactive power, Industry.

The Ring Road section on the West Ring Road - Madiun City is an alternative road which connecting the outside of Madiun city to the Madiun city. That road is a road with both side of it is a rice field. As a road, it must be clean from puddles when it rains. So that it does not cause traffic problems in the form of traffic disorder. Bad road channels have an impact on flooding due to rain and make the level of road service in the area decrease. On the other hand, the road channel in the area can also be used as a channel for removing pollutants from agricultural land in the rice fields. So that the process of remediation of agricultural land can run smoothly. This highway channel is highly influenced by the local climate, especially the existing of rainfall. Based on that, there is a need for Adequacy Evaluation of the Roadside of the Rice Fields as a drainage function in Agricultural Land Remediation, with a case study on the Ring Road channel in the West Ring Road - Madiun City. From the results of the analysis in this study, it was found that there are two size of Highway Channel Size on the Ring Road in the West Ring Road - Madiun City and both of them are in good conditions. Channel A1 with size b = 0.71 m, H = 0.36 m and h = 0.11 m. Channel A2 with size b = 0.75 m, H = 0.38 m and h = 0.11 m. The results of the design flood rainfall calculation show that there are variations in values that do not much differ in the return period of 2 years to 25 years and can be used as a reference in the management of small irrigation, drainage systems, and small-scale weir buildings, including calculation of road channels on the Ring Road in the Ring Road Section West-Madiun City. From the analysis, it was found that the road channels on the West Ring Road of Madiun City are still good and adequate. From the analysis of the square and trapezoidal dimensions, it is found that the channel discharge is > the planned discharge, so the dimensions of the channel can accommodate the flood discharge that will occur in a period of 25 years, both as a function of road drainage and as drainage in Agricultural Land Remediation in the rice fields along the road. It is suggested that the need for channel maintenance on the road sections on the Ring Road in the West Ring Road - Madiun City and for further studies regarding other road infrastructure and facilities to support road service levels and as a function for agricultural land drainage
西环路-马甸城环线段是连接马甸城外与马甸城的另一条道路。那条路是一条路，路的两边都是稻田。作为一条道路，下雨时必须清除水坑。这样就不会以交通混乱的形式造成交通问题。不良的道路通道会对雨水造成的洪水产生影响，并使该地区的道路服务水平下降。另一方面，该地区的道路通道也可以作为去除稻田农田污染物的通道。使农用地的修复过程能够顺利进行。该公路河道受当地气候，特别是降雨的影响较大。在此基础上，以西环路-马甸城环城水渠为例，有必要对稻田路边排水功能在农地修复中的充分性进行评价。从本研究的分析结果来看，西环-马甸城环线上存在两种规模的公路通道规模，且两种规模均处于良好状态。A1通道b = 0.71 m, H = 0.36 m, H = 0.11 m。通道A2尺寸b = 0.75 m, H = 0.38 m, H = 0.11 m。设计洪水雨量计算结果表明，在2 ~ 25年的回收期，其数值变化幅度不大，可作为小型排灌系统和小型堰式建筑管理的参考，包括马甸西城环城段环线道路渠道的计算。从分析中发现，马甸市西环路的道路通道仍然良好，充足。从方形和梯形尺度分析发现，河道流量为规划流量的b>，因此河道的尺度既可以作为道路排水的功能，也可以作为道路沿线稻田农田修复的排水功能，可以容纳25年的洪水流量。建议在西环路-马甸城的环路路段进行沟渠维修，并进一步研究其他道路基础设施和设施，以支持道路服务水平和作为农业用地排水的功能

Through audience interaction in the comments column, giving lots of positive and negative sentiment comments, the audience response is classified using the sentiment analysis technique of comments to find out which sentiments are positive, negative, and neutral for each comment. In this study, the data were taken from news video comments. The method used is the Support Vector Machine and the selection feature uses the Term Frequency-Inverse Document Frequency (TF-IDF).

Drinking a cup of coffee is not only a matter of taste but also a part of Indonesian’s daily life. Coffee shops which have proliferated so far proves this lifestyle. One of the best selling coffee bean products is mongoose coffee. It is a product of coffee beans which have been swallowed by mongoose and through its digestive tract. In the digestive tract, beans are being fermented by microbes (lactic acid bacteria or LAB). This fermentation process contributes to the unique taste and aroma of the coffee. The taste and aroma are very appealing to coffee lovers, resulting in the rise of demands in both local and international markets in every year. However, this leads to the escalation of mongoose hunting, threatening the population of mongoose (Paradoxurus hermaphroditus). Moreover, its limited digesting capacity also hinders the production of mongoose coffee. The present study offers an alternative to produce mongoose coffee by optimizing in-vitro fermentation which simulates the natural process of fermentation inside mongoose’s digestive organs. This in-vitro fermentation uses bacteria isolate (LAB) from mongoose’s feces collected from the local society of Jember. The study, therefore, aimed to: 1) isolate LAB from mongoose’s feces, and 2) identify the characteristics of collected LAB. Based on the result of data analysis, it was concluded that 5 LAB isolates from local mongoose’s feces were identified, namely: LAB-1 is Lactobacillus plantarum, LAB-2 is Lactobacillus brevis, LAB-3 is Leuconostoc paramesenteroides, LAB-4 is Leuconostoc mesenteroides, and LAB-5 is Streptococcus faecium
