Students tend to only follow college majors that are currently in great demand, even those college majors are based on their parents' choices. The application of computer technology can help students to find out their interests and talents so that students can choose college majors that match their interests and talents. One of the applications of computer technology is by applying an expert system. This research produces an expert system software as a tool to recommend college majors based on student interests and talents by implementing the Case Based Reasoning (CBR) method which is a method for solving problems by finding the value of proximity between old cases and new cases. The attributes used in this study were 56 items of interest and talent characteristics, which were then grouped into 8 types of talent interests. The case base in this study was 8 case bases which were compared with new cases to find the similarity value. The expert system generated from this research is able to detect the interests and talents of students, then after obtaining results regarding interests and talents, then the expert system will recommend majors in college according to the interests and talents of the students.</em></p> Yayang Eluis Bali Mawartika Mohammad Guntur Copyright (c) 2022 CogITo Smart Journal http://creativecommons.org/licenses/by/4.0 2022-12-27 2022-12-27 8 2 295 307 10.31154/cogito.v8i2.413.295-307 Pengaruh Elemen Rewards Terhadap Keterlibatan Mahasiswa Dalam Mengikuti Pembelajaran Online Pada Platform G-MOOC https://cogito.unklab.ac.id/index.php/cogito/article/view/408 <p><em>Gamifikasi terbentuk dari elemen permainan yang mampu meningkatkan motivasi atau keterlibatan seseorang menyelesaikan tugas atau pekerjaan. Karena kemampuannya terebut maka gamifikasi banyak diaplikasikan di berbagai bidang, salah satunya di bidang pendidikan. Platform G-MOOC merupakan platform Massive Open Online Courses yang dibangun dengan menggunakan pendekatan gamifikasi. Dibangun menggunakan framework MARC, platform ini dapat meningkatkan motivasi belajar mahasiswa dalam menyelesaikan kursus yang diikuti. G-MOOC terdiri dari beberapa elemen permainan yang bersifat ekstrinsik, diantaranya adalah poin, level dan leaderboards. Pengaruh elemen permainan bersifat ekstrinsik belum pernah diuji pengaruhnya terhadap tingkat keterlibatan, maka penelitian ini fokus terhadap pengujian pengaruh ketiga elemen ini terhadap motivasi mahasiswa menyelesaikan kursus. Berdasarkan pengujian didapatkan elemen point berpengaruh secara signifikan pada tingkat keterlibatan mahasiswa. Hal ini dikarenakan elemen poin berdampak langsung pada setiap aktivitas belajar yang dilakukan oleh mahasiswa di dalam platform. Penelitian selanjutnya akan diuji jenis poin apa yang paling mempengaruhi motivasi mahasiswa dalam menggunakan platform G-MOOC.</em></p> Rujianto Saputro Deasy Komarasary Rosana Fadila Sari Copyright (c) 2022 CogITo Smart Journal http://creativecommons.org/licenses/by/4.0 2022-12-27 2022-12-27 8 2 308 320 10.31154/cogito.v8i2.408.308-320 Perancangan Sistem Absensi Care Group Mahasiswa Berbasis Web Menggunakan Metode Agile Development (Studi Kasus: Universitas Advent Indonesia) https://cogito.unklab.ac.id/index.php/cogito/article/view/410 <p><em>Universitas advent Indonesia (UNAI) merupakan sebuah universitas berasrama dimana mahasiswa/i yang berkuliah pada universitas ini tinggal di dalam asrama yang telah di sediakan. Walaupun begitu, unai memberikan kebebasan kepada mahasiswa/i untuk memilih tinggal di asrama (inside) atau di luar asrama (outside). Dalam mendidik unai mengedepankan pengembangan karakter. Untuk itu, unai memberikan&nbsp; beberapa peraturan yang perlu diikuti. Salah satu peraturan yang perlu diikuti oleh mahasiswa adalah mengikuti Caregroup. Caregroup merupakan kelompok doa yang beranggotakan beberapa mahasiswa/i, ketua caregroup. yang mendampingi kelompok doa tersebut. Setiap semester unai melakukan caregroup dimana ketua caregroup yang bertugas akan mengambil absensi dari setiap mahasiswa/i. Pengambilan absensi ini masih dilakukan secara manual. Staff unai akan membagikan form absensi ke setiap ketua caregroup. Setelah itu ketua caregroup akan mengabsensi setiap mahasiswa/I dengan meminta mereka memberikan tanda tangan mereka sebagai tanda bahwa mereka menghadiri caregroup. Namun terdapat beberapa mahasiswa/i yang menandatangani mahasiswa/i lainnya sehingga data absen menjadi tidak akurat. Masalah lain yang muncul yaitu proses rekapitulasi absensi mahasiswa/i membutuhkan waktu yang cukup lama. Untuk itu dirancang sebuah sistem informasi absensi untuk memudahkan proses absensi mahasiswa/i pada saat caregroup dilakukan sehingga peraturan yang telah ditetapkan oleh UNAI dapat berjalan dengan baik. Metode yang digunakan dalam perancangan system ini adalah agile software development dimana dengan metode tersebut memungkingkan dilakukan perancangan terhadap sistem dengan waktu yang singkat. Hasil dari penelitian ini adalah sebuah rancanga dari sistem absensi caregroup didalamnya terdapat usecase diagram dimana terdapat dua actor utama yaitu ketua caregroup dan admin; class diagram; dan rancangan interface dari system ini</em></p> Jeremy Panjaitan Andrew Pakpahan Copyright (c) 2022 CogITo Smart Journal http://creativecommons.org/licenses/by/4.0 2022-12-27 2022-12-27 8 2 321 334 10.31154/cogito.v8i2.410.321-334 Implementasi Metode Indexing dan Penggunaan Subquery untuk Optimalisasi Database Rawat Jalan Rumah Sakit Menggunakan Mysql https://cogito.unklab.ac.id/index.php/cogito/article/view/415 <p><em>The need for outpatient hospital services that can be accessed quickly by the community is a very important aspect.

This study aims to determine the relationship between work posture and age with the incidence of LBP in farmers. The research method used an analytical observational research design with a cross-sectional approach. The sampling technique used was total sampling with a sample size of 80 respondents. The data collection process used the NPB questionnaire and the Rapid Entire Body Assessment (REBA). The results showed a non-significant relationship between the work position and the incidence of low back pain in farmers (p&gt;0.05) but there was a significant relationship in a positive direction between age and the incidence of low back pain in farmers (p&lt;0.05) with a correlation coefficient of 0.548. Farmers are expected to maintain an ergonomic work posture and as much as possible change positions or stretch while working in an effort to reduce the risk of low back pain. It is necessary to make an application or system through software to overcome or complete the limitations in REBA measurements which are currently only manually so that the recorded data is not only using digital photos but maybe through video recordings and analyzed automatically in the system computerized to measure angles and evaluate them automatically real-time.</em></p> <p><strong><em>Keywords</em></strong>— age, pain, posture, REBA</p> I Gede Purnawinadi Norlandha Jacob Christa Vike Lotulung Lovely Sepang Copyright (c) 2022 CogITo Smart Journal http://creativecommons.org/licenses/by/4.0 2022-12-27 2022-12-27 8 2 398 410 10.31154/cogito.v8i2.417.398-410 Public Sentiment Analysis Against Tokocrypto Exchange on Twitter Using LSTM Method https://cogito.unklab.ac.id/index.php/cogito/article/view/418 <p><em>The internet has played an important role in influencing all human activities in today's technological era. With the internet can be used for various purposes, including sharing knowledge, transacting, socializing, shopping, business, education, and many other things that can be done. While the internet is getting more and more popular, various kinds of digital transactions continue to develop, one of which is the exchange of coins for other coins which are called cryptocurrencies. Cryptocurrencies are digital assets that use strong cryptography to encrypt financial transactions, and verify asset transfers. One of the cryptocurrency exchanges for investment in Indonesia is Tokocrypto. With such enthusiasm for cryptocurrency, many Indonesians use social media such as Twitter to find information, provide opinions, as well as information. To classify public tweets on Twitter into positive and negative categories, a sentiment analysis model is needed. This study uses the Long Short Term Memory (LSTM) method, where LSTM is a neural network development that can be used for modeling time series data on Twitter users' tweets against the Tokocrypto exchange.

This is called exergaming. On the other hand, with the still ongoing pandemic, many opt to work and take their activities back at home including exercising. However, at-home exercise can be monotonous, repetitive, and even discouraging for many, thus an exergaming can be a solution. In this research we created a Virtual Reality-based exergaming that encourage its users to exercise and have fun at the same time.

To support this understanding, quality human resources are urgently needed as a priority for national development, the position and role of teachers is increasingly important in preparing the nation's young generation, especially in facing the current global era. The problem that occurs in the selection of outstanding teachers in early childhood education is that the selection is still subjective, causing it to be unfair. For this reason, a decision support system is needed that can overcome these problems by using the Simple Additive Weighting (SAW) method as a basis for decision making. The method uses 5 criteria, namely education, pedagogy, professionalism, personality and social. The purpose of the support system is to make it easier and faster to determine outstanding teachers so that decisions are objective. Based on the results of the calculations in this study, the results for teacher 1 with a value of 0.85, teacher 2 obtained a value of 0.70, teacher 3 obtained a value of 0.9375, teacher 4 with a value of 0.8625 and teacher 5 with a value of 0.8625 0 ,7625. For this reason, the selection of kindergarten level teachers obtained the best alternative with the highest score being teacher 3 (V3) with a value of 0.9375.</em></p> Hamidah Hamidah Okkita Rizan Hengki Hengki Copyright (c) 2022 CogITo Smart Journal http://creativecommons.org/licenses/by/4.0 2022-12-27 2022-12-27 8 2 549 560 10.31154/cogito.v8i2.430.549-560 Perancangan Sistem Penyiraman Tanaman Aglonema https://cogito.unklab.ac.id/index.php/cogito/article/view/432 <p style="font-weight: 400;"><em>Aglaonema adalah tanaman hias mengalir dalam keluarga arum Aracae yang banyak diminati oleh masyarakat saat ini dan salah satu kemampuan tanaman aglaonema adalah dapat hidup pada kondisi lingkungan dengan intensitas cahaya rendah yang dapat dipelihara pada ruangan seperti kantor dan dekorasi ruangan. Kunci sukses budidaya aglaonema adalah penyiraman, dan ini harus dilakukan dengan baik. Penyiraman tanaman aglaonema dapat dilakukan secara konvensional yaitu dilakukan oleh manusia. Namun, berdasarkan pengamatan, metode konvensional ini menimbulkan masalah dan kendala utamanya adalah petani kesulitan dalam memeriksa dan memantau intensitas air dan kelembaban di dalam media tanam. Dengan Adanya teknologi IoT (Internet of Things) semua perangkat yang terhubung dengan internet dapat dikendalikan dan dipantau menggunakan smartphone dimanapun kita berada serta pengontrolan penyiraman dapat terjadi secara otomatis. Untuk mengatasi masalah tersebut di atas, kami merancang sistem e-watering yang memungkinkan penyiraman tanaman aglaonema dilakukan secara digital menggunakan sistem aplikasi IoT. Adapun untuk perancangan prototipe sistem penyiraman elektronik tanaman Aglaonema meliputi Unified Modeling Language, dalam hal ini kita hanya akan fokus pada use case diagram, use case scenario, serta Interface design. Penulis menggunakan model proses prototipe sebagai kerangka konseptual penelitian, namun dalam artikel ini kami hanya membahas pada tahap desain saja.</em></p> Marchel Thimoty Tombeng Copyright (c) 2022 CogITo Smart Journal http://creativecommons.org/licenses/by/4.0 2022-12-27 2022-12-27 8 2 561 573 10.31154/cogito.v8i2.432.561-573 Can Early Programming Performance Predict Computer Science Students’ Success? https://cogito.unklab.ac.id/index.php/cogito/article/view/452 <p><em>Investigating the possibility of lower-level computer programming courses predicting future performance of computer science students has received a lot of attention from scholars. This study mainly aimed to predict the success of computer science students based on their performance in the first two computer programming courses, namely Computer Programming I and Computer Programming II. The study employed a quantitative correlational design. Six years of data from graduating students were analyzed. The results demonstrate that the better the grade on Computer Programming I and II, the shorter the study duration. When further analysis was conducted to find out whether gender diversity exists, the results demonstrated that in Computer Programming I and II, female students outperformed males. Statistically, this difference was only significant in Computer Programming I. A greater proportion of female students graduated on time, yet it is not statistically significant.</em></p> Debby Erce Sondakh, S.Kom, M.T, Ph.D Stenly Richard Pungus Copyright (c) 2023 CogITo Smart Journal http://creativecommons.org/licenses/by/4.0 2022-12-27 2022-12-27 8 2 574 584 10.31154/cogito.v8i2.452.574-584
