The samples used in this study were long bean seeds of parade tavi, kanton tavi, branjangan, and petiwi varieties. For each variety, 400 samples were taken for training data and 200 samples for testing data, so the total sample was 2400 long bean seeds. The research stages include image acquisition, image retrieval, image variable estimation, image processing program development, data analysis, ANN training, long bean variety identification program preparation, and program validation. The results showed that ANN with 10 hidden layers is the best model to develop a long bean seed identification.

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.","PeriodicalId":13778,"journal":{"name":"International Journal of Applied Science and Engineering","volume":"258 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75969154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.

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.

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","PeriodicalId":13778,"journal":{"name":"International Journal of Applied Science and Engineering","volume":"531 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77139607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
