Abstract

Satya Wacana Saints Salatiga is one of the professional teams that compete in Indonesian Basketball League (IBL). Player evaluation has been done as an effort to maintain the quality and performance of all players which can be used as team records. They can also make a couple of improvements within the team for the next season. Classifying the players performance by using the fuzzy c-means algorithm is the aim of this research. Player performance is determined based on five kinds of player statistical criteria, namely points, assists, blocks, rebounds, and steals from each position. The assessment carried out in this study is using weighting criteria for each position. The grouping by weighting aims to get the highest to the lowest scores from each player so that they can be grouped into three performance groups; good, moderate, and poor performance. The results of the fuzzy c-means grouping of 15 players of the Satya Wacana Saints Salatiga team with weighting obtained three players with good performance, five players with moderate performance, and seven players with poor performance. Meanwhile, the results of the fuzzy c-means grouping without weighting obtained five players with good performance, three players with moderate performance, and seven players with poor performance. Both grouping results are compared with the actual performance data. The result of the comparison was found that the grouping with weighting resulted in an accuracy rate of 100% and the grouping without weighting resulted in an accuracy rate of 86.67%. Grouping with weighting on different statistical values for each player position has an effect on player performance. Each player position has different strengths in scoring points, assists, rebounds, steals, block shoots, and field goals.

Abstract

Many things from the life sector have used the existence of technology. Where a technology is able to help various problems in various fields such as livestock and agriculture. Computers have been included in it as a tool to do a job or identify existing problems. However, sometimes as a practitioner in the field of animal husbandry, especially qurban animals, they come to the conclusion that it is often found that sacrificial animals in the market that want to be sacrificed do not meet the requirements both in syari ah (law) and health. With the application of determining the feasibility of sacrificial animals according to the Syariah using the web-based Simple Additive Weighting (SAW) method. This system is later expected to be able to determine whether or not a sacrificial animal will be sacrificed so that the community or people who sacrifice are not harmed and the reward for the sacrifice is perfect.

Abstract

Tsunami adalah salah satu bencana alam yang dapat terjadi kapan saja yang keberadaannya tidak dapat dihindari. Kabupaten Kebumen adalah salah satu daerah yang bertempat di bagian pantai selatan Provinsi Jawa Tengah yang memiliki risiko terkenanya bencana tsunami. Hal ini terjadi akibat lokasi dari kabupaten kebumen yang berada dekat dengan perairan dan memiliki banyak luas wilayah pada dataran rendah. Penelitian ini dilakukan agar dapat memberikan informasi mengenai risiko yang dapat terjadi pada wilayah tersebut dengan melakukan prediksi dan klasifikasi dengan menggunakan data dari Citra Landsat-8 OLI yang diambil dari USGS serta memanfaatkan 5 indeks vegetasi yaitu NDVI, NDBI, NDWI, MNDWI, dan WI dengan penerapan metode Support Vector Machine (SVM) yang merupakan salah satu metode machine learning yang digunakan untuk klasifikasi. Pada penelitian ini didapatkan ada 11 desa yang diprediksi berisiko tinggi terkena tsunami dengan nilai akurasi yang didapatkan sebesar 0.945 dan nilai kappa sebesar 0.914 dimana semakin tinggi nilai yang didapatkan maka semakin tinggi juga ketepatan hasil prediksi yang diperoleh.

Abstract

Provide convenience and information to BPBDs and people living in flood-prone environments that are usually unknown to homeowners without getting information about the arrival of floods in the area.  So we need a system that can detect the water level of the river. For that, it is necessary to install a device that can read the water level in the form of an ultrasonic sensor and a microcontroller as well as a GSM SIM900A module. The research method used is literature study, problem analysis, system design and implementation.The results achieved in this study are able to help provide information in the form of sirens and SMS services in the form of short messages about flood alert levels that are sent to the community and the BPBD.

Abstract

Pada saat bencana alam yang mengakibatkan infrastruktur jaringan dan komunikasi di suatu wilayah menjadi lumpuh, dibutuhkan suatu sistem komunikasi yang berjalan tanpa infrastruktur jaringan. Komunikasi yang dilakukan dalam penanganan bencana dapat dilakukan menggunakan perangkat komunikasi yang berbasis Mobile ad-hoc Network (MANET) yang tidak membutuhkan infrastruktur jaringan, atau dapat juga menggunakan perangkat komunikasi yang berbasis wireless mesh network (WMN) yang menggunakan beberapa node router yang ditempatkan secara terbatas. Pada penelitian ini, dilakukan simulasi sistem komunikasi berbasis jaringan MANET dan WMN menggunakan Network Simulator 2 versi 2.35 dengan protokol routing ZRP dan TORA. Simulasi diuji dengan empat skenario yang berbeda. Parameter yang digunakan untuk menguji kinerja jaringan adalah packet delivery ratio, end to end delay, throughput dan routing overhead. Dari hasil pengujian, protokol routing TORA pada skenario node sudah tersebar dan protokol routing ZRP untuk seluruh skenario di jaringan WMN memiliki nilai rata-rata packet delivery ratio yang tinggi. Sedangkan protokol routing TORA pada skenario node yang menyebar memiliki nilai rata-rata end-to-end delay yang rendah serta throughput yang tinggi. Pada jaringan MANET memiliki nilai rata-rata end-to-end delay yang rendah serta throughput yang tinggi dan protokol routing TORA dengan skenario node yang menyebar memiliki nilai rata-rata packet delivery ratio yang tinggi serta routing overhead yang tinggi.

Abstract

There are problems that still exist in online learning including limited-reach networks, inadequate facilities and infrastructure, and others. This study discussed the analysis of sentiment which used the Na ve Bayes Classifier (NBC) method with XGBoost feature selection as a performance improvement that took data from news portals. The results of this study showed that graph data on the application of online learning forms in Indonesia had a "Negative" opinion. Performance testing of the NBC method based on XGBoost feature selection was conducted four times. The first experiment resulted in an accuracy value of 60.18% with 50/50 split data. The next experiment had an accuracy value of 56.92% with 70/30 split data. After that, the third experiment resulted in an accuracy value of 65.90% with 80/20 split data. The result of the last experiment was an accuracy value of 63.63% with 90/10 split data. After using XGBoost feature selection, it produced an accuracy of 60.18%, 67.69%, 70.45%, and 77.27%. The study also produced the highest average score at 10-Fold Cross-Validation in the second trial with a score of 65.62%.

Abstract

Sekolah perlu melakukan peningkatan kinerja guru dengan mengadakan pemilihan guru terbaik. Karena itu, penelitian ini mengulas sistem pendukung keputusan pemilihan guru terbaik pada   SD Negeri Periuk 3 Tangerang. Namun ada permasalahan yang terjadi, antara lain banyaknya jumlah guru sehingga sulit memilih guru terbaik, belum terdapatnya metode yang dipergunakan sebagai pembobotan nilai kriteria, dan juga belum adanya Sistem Pendukung Keputusan (SPK) yang membantu kepala sekolah. Untuk itu, sebagai solusi dari masalah yang ada, diusulkan pembangunan sitem pendukung keputusan pemilihan guru terbaik, supaya hasil yang dicapai semakin objektif dan dapat meningkatkan kualitas mengajar di sekolah. Sistem ini di bangun dengan menerapkan metode Analytical Hierarchy Process (AHP) juga menggunakan beberapa kriteria untuk menetapkan bobot yaitu nilai kehadiran, nilai kedisiplinan, nilai berpakaian, nilai skill. Selain itu, metode AHP juga dapat memberikan urutan prioritas alternatif. Penelitian ini bertujuan untuk membangun SPK pemilihan guru terbaik yang mempermudah pihak sekolah dalam penentuan guru terbaik serta dapat mengurangi tingkat kesalahan dalam penilaian, dan menghasilkan metode yang tepat untuk pemilihan guru terbaik. Selain itu hasil akhir alternatif guru terbaik yang terpilih, juga dapat menjadi motivasi kepada guru untuk meningkatkan kinerja sehingga menghasilkan kualitas kerja yang baik.
