Background: The Rapid growth of technological developments in Indonesia had resulted in a growing amount of information. Therefore, a new information retrieval environment is necessary for finding documents that are in accordance with the user’s information needs.Objective: The purpose of this study is to uncover the differences between using Relevance Feedback (RF) with genetic algorithm and standard information retrieval systems without relevance feedback for the Indonesian language documents.Methods: The standard Information Retrieval (IR) System uses Sastrawi stemmer and Vector Space Model, while Genetic Algorithm-based (GA-based) relevance feedback uses Roulette-wheel selection and crossover recombination. The evaluation metrics are Mean Average Precision (MAP) and average recall based on user judgments.Results: By using two Indonesian language document datasets, namely abstract thesis and news dataset, the results show 15.2% and 28.6% increase in the corresponding MAP values for both datasets as opposed to the standard Information Retrieval System. A respective 7.1% and 10.5% improvement on the recall value at 10th position was also observed for both datasets. The best obtained genetic algorithm parameters for abstract thesis datasets were a population size of 20 with 0.7 crossover probability and 0.2 mutation probability, while for news dataset, the best obtained genetic algorithm parameters were a population size of 10 with 0.5 crossover probability and 0.2 mutation probability.Conclusion: Genetic Algorithm-based relevance feedback increases both values of MAP and average recall at 10th position of retrieved document. Generally, the best genetic algorithm parameters are as follows, mutation probability is 0.2, whereas the size of population size and crossover probability depends on the size of dataset and length of the query.Keywords: Genetic Algorithm, Information Retrieval, Indonesian language document, Mean Average Precision, Relevance Feedback

Aspek User Experience (UX) sangat penting diperhatikan dalam pengembangan aplikasi mobile. AIS Mobile merupakan sistem yang mampu menangani permasalahan akademik di UIN Syarif Hidayatullah Jakarta. Berdasarkan hasil observasi dan wawancara kepada lima pengguna AIS Mobile, ditemukan bahwa UX yang sekarang ternyata kurang baik, serta adanya beberapa review negatif di Playstore. Tujuan penelitian ini adalah melakukan pengukuran UX pada AIS Mobile untuk user-centered metric menggunakan HEART (Happiness, Engagement, Adoption, Retention, Task Success) Framework supaya bisa mendukung keputusan pengembangan produk sesuai kebutuhan penggunanya. Pada penelitian ini, kuesioner disebarkan kepada 100 responden. Hasil data kuesioner diuji dengan pengujian validitas dan reliabilitas, kemudian diolah untuk divisualisasikan dalam bentuk dashboard. Berdasarkan data yang sudah diolah, tidak ada satupun set Goal-Signal-Metrics pada HEART framework yang tercapai karena nilai metrics yang didapatkan masih di bawah nilai yang diharapkan. Nilai metrics yang didapatkan adalah Happiness sebesar 62.27%, Engagement sebesar 71.28%, Adoption sebesar 64%, Retention sebesar 68.48%, dan Task Success sebesar 61.11%. Untuk mencapai set Goal-Signal-Metrics pada HEART framework, perlu dilakukan re-design terhadap tampilan AIS Mobile secara UX maupun UI (User Interface), pembuatan fitur push-notification untuk info update aplikasi, sosialiasi pemakaian AIS Mobile ke mahasiswa, serta perbaikan atau peningkatan kualitas fitur-fitur di AIS Mobile.

The first aim of this research is to analyze the effect of social economic characteristics and communication behavior of the farmer on the probability of adopter category differences and on the preference of source of information. The second aim is to analyze the effect of adopter category on the preference of source of information. This research has been conducted in the broiler farm at Karanganyar, Sragen, and Boyolali Central Java by using research based method of descriptive analysis. The result of the research shows that there are differences in social economic characteristics and communication behavior of the farmer between early and late adopter categories; they are age (p0.01), formal education level (p0.01), cosmopoliteness level (p0.01), and farming experience (p0.05). The result of logistic binominal regression test on social economic characteristics shows that age and formal education level influence the difference of adopter category significantly (p0.05). The characteristics of farmers haveeffect on the preferences of personal and non personal information source, namely age, formal education level, and cosmopoliteness level, which have significant effect (p0.05). Additionally, the result shows that the adopter category has very significant effect (p0.01) on the preference of information source. The conclusion of the research is that the younger farmers, higher formal education level, longer experience, and higher level of active searching information seemed to have higher probability to become the early adopter. The farmers have higher preference on non personal information source.

Increasing end-user satisfaction (EUS) on mobile-based AIS is influenced by an actual usage (AU). AU increases if Small Medium Enterprise managers feel the perceived ease of use (PEOU) and perceived usefulness (PU) of using mobile-based AIS. This study aims to (1) analyze the effect of PEOU and PU on AU, (2) analyze the effect of PEOU and PU on EUS on mobile-based AIS, (3) analyze the effect of AU on EUS on mobile-based AIS, and (4) analyze the effect of PEOU and PU to EUS on mobile-based AIS through AU. The results of this study are (1) PU has a positive effect on AU and PEOU has a negative effect on AU because to improve AU requires a guidebook that is easy to learn and the lack of ability to use system applications make it not easy, (2) PEOU and PU affect EUS on Mobile-based AIS but the most positive and dominant influence on EUS on mobile-based AIS is PU, (3) AU has a positive effect on EUS on mobile-based AIS, and (4) PEOU negatively affects EUS on mobile-based AIS through AU due to the use of AIS based on mobile, which is done repeatedly and for a long time is still unable to mediate PEOU and SME managers feel difficult to use the purchasing and sales system application to produce on time reports.

Technology has a big role in today's life, especially helping the business process activities within a company or organization, making the business process easier. For this reason the creation of a new student admission system and entrance examination in a high school, which affects the speed and accuracy of the final grades in the process. The method used is the Simple Additive Weighting (SAW) method, which has more precise and accurate advantages compared to other decision-making models, because its ability to conduct an assessment is based on the value of criteria and weighted preferences that have been determined. The design and analysis of new student admissions and entrance examination exams can help and overcome existing problems. New student admission and admission test programs have the advantage of being a computerized student registration, conducting computer-based entrance examination exams and can process data through the system thereby reducing the risk of errors in making reports.
