Early detection of HIV is a crucial step to reducing transmission and increasing the success of HIV treatment. The sooner HIV is detected, the sooner treatment can be carried out so that this infection can be controlled and does not develop into AIDS. Therefore, the purpose of this study is to forecast the Number of New HIV Cases in Indonesia based on 34 Provinces so that the government can obtain information early on to determine the right policy to suppress the increasing number of new HIV cases in Indonesia. This research proposes forecasting using a Machine Learning algorithm with the Levenberg-Marquardt technique. The research data is data on the number of new HIV cases by province obtained from the 2021 Indonesian Health Profile book issued by the Ministry of Health of the Republic of Indonesia. This research will be analyzed using three network architecture models, 3-15-1, 3-20-1 and 3-25-1. Based on the analysis of the three models used, the results show that the 3-15-1 model is the best because it produces a higher accuracy level than the other two models, which is 88%. It can be concluded that the Levenberg-Marquardt technique with the 3-15-1 model is quite suitable for forecasting new cases of HIV in Indonesia. Based on the prediction results, the number of new HIV cases by the province in Indonesia at the end of 2022 decreased significantly compared to 2021, which was 24668 compared to 36902 or reduced by around 12 thousand cases.
The price of crude oil in Indonesia is still very volatile it cause of strongly influenced by the demand and supply mechanism. The other factor is the fundamental factor, the non-fundamental factor, and the influence and policy of OPEC factor. Refined petroleum is indispensable in life, used for various human purposes for fuels such as gasoline and kerosene, asphalt, and some of the chemical reagents used to make plastics and medicines. These crude oil prices Information in Indonesia are open and officially published by the Ministry of Energy and Mineral Resources website from 2017 until now. That information is about the monthly prices of several major oil refineries in Indonesia. There is no information about the resume of price fluctuations in one oil refinery, and there is no information on the grouping of oil refineries based on the selling price of the refinery. This study aims to group crude oil price categories in Indonesia using the x-means method. This study is one of the efforts to provide general information about crudes oil price clusters based on major refineries in Indonesia to the public. The results showed that the grouping types of crude oil prices throughout 2020 with the X-Means method contained four optimal clusters with the highest price characteristic being the type of crude oil which is cluster 1, then cluster 0, cluster 3, and the last is cluster 2.
Di Indonesia evaluasi kinerja seorang Pegawai Negeri Sipil dinilai berdasarkan SKP dan Perilaku Kerja. Evaluasi yang diusulkan adalah penilaian untuk perilaku kerja PNS. Penilaian dilakukan untuk subkriteria terhadap masing-masing pegawai yang dievaluasi. Pemilihan pegawai ternilai dan penentuan evaluator dilakukan pada tahap 360-degree Feedback. Kemudian penilaian subkriteria dibentuk oleh AHP yang digabungkan dari 3 matriks evaluator setiap subkriteria. Berdasarkan regulasi pemerintah Indonesia tahun 2011 nilai perilaku kerja tidak lebih dari 40%, dan hasil rangking evaluasi kinerja perilaku kerja pegawai memiliki nilai terendah 13,6 % dan tertinggi adalah 39,8%. Sehingga model yang diusulkan dapat dijadikan alat ukur evaluasi untuk kinerja pegawai pemerintah (PNS) untuk mendukung pengambil keputusan.
Many parents give gadgets to toddlers early on the grounds that they are learning media, communication tools and play bring their own anxiety. This condition makes parents start complaining about changes in children's behavior when they are not given gadgets according to their wishes. Children cry loudly, throw tantrums and behave violently. This study aims to determine the relationship between the use of gadgets in toddlers and the occurrence of temper tantrums. The study was conducted using a quantitative correlation approach to 106 parents who entrusted their children to day care. Intake of respondents using total sampling technique with a research time of 1 month. Data collection was carried out using primary data from the results of distributing questionnaires using gadgets and temper tantrum questionnaires to parents of children. The questionnaire was adopted from Lusia research which had been tested for validity and reliability, with a value of α = 0.841. Data analysis used univariate and bivariate chi-square analysis. The results of the study concluded that there was a significant relationship between the use of gadgets and the incidence of temper tantrums in toddlers with a p value of 0.021 (p <0.05). Parents are expected to replace gadgets with other games that can hone growth and development, as well as for assistants at day care centers to be able to coordinate with parents in terms of increasing parental understanding regarding the influence of using gadgets and selecting types of games that are suitable for toddlers.
