OSIS is the highest organization in the school that functions to mobilize students to be able to contribute to various activities that support the school. To get the OSIS chairperson, it begins with the registration of candidate candidates, then continues with a meeting to determine the candidate for the OSIS chairman. This is considered ineffective because there are no special criteria, so it is not right on target. In addition, the selection process in this way takes a long time. The purpose of this study is to develop a decision support system to select a candidate for the OSIS chairman by using the profile matching method through the required criteria so that the process will be faster and more precise. The profile matching method has the ability to determine the assessment based on the existing attributes. Based on the calculation of profile matching manually and the system built shows the same results. Based on the case study, candidate 1 got a final score of 9.14 and candidate 2 got a final score of 9.215. The results of the assessment of test cases that have been filled in by system users get the system functions developed in accordance with the test criteria carried out. As for the results of black-box testing, the value is 100%, this means that the system is in accordance with the functions and needs.

There are so many high school students who do not understand their own criteria because they are confused about choosing the best college. So that most students choose colleges according to the interests of their friends, without finding out which colleges match their criteria. Not even a few of these students follow the directives of their parents. As a result of this, it causes major errors, regrets studying at these institutions and some even move and some even stop. Though each major is tailored to the wishes of students in the future. So that these problems can be solved, then a decision support system is made which will make it easier for students who want to continue to a bachelor's degree or diploma. There are many methods used in decision support systems, one of which is used in this study is the WASPAS method. The way WASPAS works is easy to reach, resulting in a sequence of universities and majors according to their respective criteria, starting from the highest to the lowest. After being applied with the WASPAS method, the final result is the best alternative in alternative A2 with a result value of 14,297.

The influencer industry has emerged as a result of social media disruption, and its members can affect audience interest in the goods and services being advertised. Because advertising performance on social media is more quantifiable than it is with traditional media, using influencer services is thought to be preferable. Influencer rates are often dependent on reach, engagement, and follower count. However, since there is no reference standard used in determining the prices, it could harm one of the parties. In order to reduce the impact of losses for both influencers in giving rates and clients in accepting rate offers, this study intends to propose a solution in the form of a machine learning-based influencer rate prediction model that can be used as a reference. The stages of this study are literature review, data gathering, pre-processing of the data, linear regression model development, and model evaluation. Five different models were produced as a result of this investigation. One of the best models has an MAE of 145401.484375, an MSE of 7.222241e+10, and an RMSE of 268742.250. These findings are affected by the hyperparameter learning rate of 0.001 and the epoch of 1,000. Most of the test data have not been completely represented by the model. The little number of datasets utilized for training, only 161 rows with 4 positively correlated attributes, is one of the reasons why the model is not really optimal. Nevertheless, from the standpoint of using a relatively small dataset, the model developed in this study is quite successful because several of the prediction results are fairly near to the real value, one of which is the prediction value with an error difference of −347.69.

Today, the use of information systems is important, especially in archiving important data. Advances in technology have made conventional recordings begin to switch to digital. The case study in this research is to make an information system on one of the electric power systems, namely the distribution system. In this distribution system there is a substation that contains important components in the distribution of electricity from transmission to consumers. Generally, data collection at distribution substations uses manual recording on paper. This becomes less effective when it finds conditions of archiving data that have been in the past. Therefore, an application is designed that can help the authorities to record android-based data and websites. This information system is made using Rest API which facilitates communication via the internet. From the research that has been done, the performance between the mobile application and the website is good. Website performance produces applications on the web that have good results, namely 99, while Android is 93 from a maximum value of 100.

Optimizing the use of home yards is one of the efforts to improve food security in agriculture through vegetable cultivation. The number of vegetable seed products causes someone who will buy vegetable seeds to first seek information about each vegetable seed, thus taking a long time to make a decision. This study aims to implement the Multi-Attribute Decision Making (MADM) approach with Aggregated Sum Product Assessment (WASPAS) on a vegetable seed selection decision support system, in order to obtain the best alternative that suits your needs. The WASPAS method has the ability to solve multi-attribute by optimizing the assessment for selecting the highest and lowest values in obtaining the best alternative. Based on the case studies conducted, the WASPAS method was able to determine the best vegetable seeds with the best alternative results, namely Known You Seed Brokoli F1 (A2) with a Qi value of 0.7854, then followed by an alternative to Infarm Benih Kangkung (A1) with a Qi value of 0, 7710, Daily Farm Sawi Putih (A3) with a Qi value of 0.7330, Mira Mentimun Hibrida F1 (A4) with a Qi value of 0.7225 and Benihpedia Daun Bawang (A5) with a Qi value of 0.5992. The developed system produces a valid WASPAS method, because the results are no different from manual calculations. In addition, the results of black-box testing show that the developed system has been running well.

Covid-19 cases in Bali in the period October to November 2020 experienced an increase which could cause hospitals to experience an increase in demand for health services. Hospitals are one of the most important departments during the Covid-19 pandemic. As a health service agency, the hospital must provide quality services to all levels of society who visit. In realizing optimal public health services, hospitals need a system that supports services to the community. In carrying out the Covid-19 test, the patient registers at the admission, the Nakes (Health Personnel) enters the patient's identity manually using the Microsoft Excel application. In the registration process, there are often discrepancies in the patient's name, date of birth, address and telephone number as well as other identities due to input errors. The large number of patients who register to do the Covid-19 test makes the Nakes (Health Personnel) take a long time, the time required to collect the data is 10 minutes and results in a queue buildup. To overcome this, applying Optical Character Recognition (OCR) can make it easier for Nakes (Health Personnel) to register and input KTP / KIS data automatically, thereby reducing patient data collection errors. Seeing this problem, from this research, a website was built by applying Optical Character Recognition (OCR) and the development method used was the Waterfall method and the suitability of the system built was tested using the black box testing method. This system gets a percentage of 79.4% which means both from admin and doctor respondents, and gets a percentage of 92.8% which means very good from user respondents (patients).
