The National Human Rights Commission Library in the development of technology utilizes an information retrieval system for online public access (OPAC), to measure the effectiveness of a retrieval system. This study aims to determine the effectiveness of information retrieval systems through recall and precision assessment. The method of this research is a quantitative method with the type of experimental approach. The research subject is a collection stored in the Library database, while the object is the SLiMS application information retrieval system. Methods of collecting data using observation, tests, documentation, and interviews. The results showed that the average recall and precision values in the retrieval system at the National Human Rights Commission Library through a simple search feature obtained an average recall value of 99.8% and an average precision of 99.6%. From the results obtained, the information retrieval system at the National Human Rights Commission Library was said to be effective, and helped library service users to find the desired information.

AbstrakKualitas pelayanan adalah salah satu keunggulan kompetitif, karena pelayanan yang baik adalah salah satu faktor dasar yang mampu mempengaruhi tingkat kenyamanan penerima layanan. Pelayanan publik oleh aparatur pemerintah dewasa ini masih banyak dijumpai kelemahan, sehingga belum dapat memenuhi kualitas yang diharapkan masyarakat. Penelitian ini ditujukan untuk melihat seberapa besar kepuasan pelayanan, dan pengaruh tingkat pelayanan terhadap tingkat kepuasan berdasarkan Logika Fuzzy Inference System Model Mamdani. Ada empat variabel input yang digunakan yaitu kejelasan informasi, kejelasan persyaratan, kemampuan petugas dan ketersediaan sarana dan prasarana untuk menghasilkan output kepuasan pelayanan. Berdasarkan tahapan-tahapan menggunakan Logika Fuzzy Inference System Model Mamdani mulai dari pembentukan himpunan fuzzy, aplikasi fungsi impilkasi, komposisi aturan sampai proses penegasan (defuzzyfikasi), dapat dibuktikan adanya korelasi antara variabel-variabel input sehingga dapat menentukan output hasil kepuasan pelayanan. Hasil penelitian ini diharapkan dapat digunakan oleh pihak instansi, sebagai pendukung sistem keputusan terhadap hasil penilaian yang diberikan oleh masyarakat untuk pelayanan yang dirasakan. Pengembangan penelitian ini kedepan nya akan diuji coba kembali dengan menambahkan lebih banyak variabel dan akan dibuat sebuah interface untuk memudahkan pemprosesan hasil penilaian kualitas pelayanan pengaduan masyarakat.  Kata Kunci: Pelayanan, Fuzzy Mamdani, Logika Fuzzy.AbstractService quality is one of the competitive advantages, because good service is one of the basic factors that can affect the comfort level of service recipients. Public services by the government apparatus today are still often found to be weak, so that they cannot meet the quality expected by the community. This study is intended to see how much service satisfaction is, and the effect of service levels on satisfaction levels based on Mamdani Model Fuzzy Inference System Logic. There are four input variables used namely clarity of information, clarity of requirements, ability of officers and availability of facilities and infrastructure to produce service satisfaction output. Based on the stages using Mamdani Model Fuzzy Inference System Logic starting from the formation of fuzzy sets, application of the implementation function, composition of the rules until the confirmation process (defuzzyfication), it can be proved the correlation between input variables so that it can determine the output of service satisfaction. The results of this study are expected to be used by the agency, as a support system for the decision on the results of the assessment given by the community for perceived services. The future development of this research will be re-tested by adding more variables and an interface will be created to facilitate the processing of the results of the quality assessment of public complaints services. Keywords: Service, Fuzzy Mamdani, Fuzzy Logic.

One property that is currently being glimpsed by investors is an apartment. Property consulting companies as one of the service provider companies that become a link between apartment owners and apartment enthusiasts, have an important task in terms of providing information about the assessment of the offered institutions. This study will conduct a trial on the accuracy of apartment assessment predictions using the Support Vector Machine (SVM) method, then will be compared again with the results of the accuracy of the assessment method Support Vector Machine (SVM) combined using the optimization method Particle Swarm Optimization (PSO). The results of the combination of the application of SVM and PSO are used to optimize attribute selection in apartment valuation to improve the accuracy of using the SVM method. This study shows that the Particle Swarm Optimization (PSO) Support Vector Machine (SVM) method is a pretty good method of data classification, because it can seen from the increase in accuracy of 2.84% and AUC of 0.003. Subjects (attributes) that affect apartment valuation are seen from rent prices (price range), city (apartment location), size (area), furnisihing (equipment), bedroom (number of bedrooms), bathroom (number of bathrooms) and maids badroom (number of maid rooms). The results of the attribute testing showed that city attributes (apartment locations), furnisihing (equipment) and maid badroom (number of maid rooms) greatly influenced the valuation of an apartment.

Current progress in the development of information technology, makes every government agency or private organization, must be able to balance and develop capabilities in terms of data and information management. Komnas HAM is one of the government agencies, which is directly related to the provision of public information to the public, requiring an information system for the process of providing this information flow. The public is allowed to submit requests for data, such as data on complaints of cases that have occurred, for which information is needed. Currently the process of requesting data is still being carried out by the public coming directly to fill out the data request form, then it will be processed by the relevant section at Komnas HAM, after the data request is approved, the requested complaint data document will be sent via POS. This system still has weaknesses, because the applicant's side cannot monitor the progress of the data application process whether it is approved or not, the applicant is only asked to wait and if the document is sent by post, the application is approved. This Web-Based Smartmaps Complaint Data Application Information System can be a solution, to facilitate the process of requesting data requested by the public. This system was designed by applying the Rapid Application Development (RAD) method in the system design stage, and the system will be built using the programming language PHP 7.3, MySQL 5.7, Nginx and PHP-FPM 7.4, Laravel 7 Framework and Bootstrap Template Design 4.0. This system, after testing using blackbox testing in its application, is proven to have provided convenience and the best service to people who have an interest in complaint data.
