Abstract

One of the benefits of advancing technology is its ability to serve as a medium for entertainment. The online game Mobile Legends has gained widespread popularity and attracts a broad audience, including university students. While playing Mobile Legends can offer cognitive stimulation, enjoyment, and entertainment, it can also lead to excessive addiction, which may negatively affect users’ mental health. This study applies a fuzzy logic approach, which processes input data through fuzzy rules involving fuzzification, fuzzy inference, and defuzzification. Three input variables are used: Playing Time, Emotional Level, and Stress Level, with a single output variable: Health Index, which reflects the user's mental health condition. The purpose of this study is to evaluate the impact of the Mobile Legends online game on users’ mental health using fuzzy logic implemented in MATLAB. Based on the results, the manual Mamdani fuzzy analysis yielded a defuzzification result of 44.75. Meanwhile, using MATLAB Fuzzy Mamdani Toolbox (version 2023b) with input values of Playing Time (69), Emotional Level (68), and Stress Level (65) produced an output of 52.7. Both results fall within the fuzzy domain of “Agree” [40, 60, 80], indicating that prolonged playing time of Mobile Legends can influence players’ mental health.

Abstract

Mayoritas masyarakat di Mendahara ilir berprofesi sebagai nelayan Sondong merupakan alat tangkap yang banyak dioperasikan oleh nelayan di Mendahara ilir. Alat tangkap Sondong adalah alat tangkap aktif yang tujuan operasinya adalah menangkap udang. Tujuan dari penelitian ini untuk mengetahui Keanekaragaman Crustacea dengan menggunakan alat tangkap Sondong di Perairan Mendahara Ilir Kabupaten Tanjung Jabung Timur. Penelitian ini dilakukan di Perairan Mendahara Ilir Kabupaten Tanjung Jabung Timur selama 30 hari, dari tanggal 15 Desember 2021 sampai 15 Januari 2022. Metode yang di gunakan dalam penelitian ini adalah metode eksperimen. Data yang di himpun dalam penelitian ini adalah jumlah total udang dan ikan (ekor), berat per jenis dan berat total udang dan ikan (kg), dan parameter lingkungan. Analisis data yang digunakan adalah komposisi jenis, indeks keanekaragaman, indeks keseragaman dan indeks dominansi. Hasil dari penelitian ini Jumlah hasil tangkapan yang didapat selama penelitian sebanyak 776,62 kg. Hasil tangkapan crustacea di Mendahara Ilir adalah udang loreng (Parapenaeopsis sculptilis), udang kapur (Metapenaeus dopsoni), udang jerbung (Penaeus merguiensis), udang agogo (P.indicus), udang mantis (Harpiosquilla raphidea), rajungan (Portunus pelagicus), belangkas (Carcinoscorpius). Selain itu hasil tangkapan sampingan (By-Catch) sondong seperti ikan selar (Selaroides leptolepi), gulamah (Johnius trachycephalus), Pari (Dasyatis sp), ikan lidah (Cynoglossus lingua). Hasil tangkapan tertinggi, yaitu udang Loreng sebanyak 196,2 kg hasil tangkapan terendah yaitu udang mantis sebanyak 2,63 kg, hasil indeks keanekaragaman 0,98, indeks keseragamannya yaitu 0,50 dan dominansi yaitu 0,43. Kesimpulannya adalah Keanekaragaman crustacea hasil tangkapan sondong di perairan Mendahara Ilir Kabupaten Tanjung Jabung Timur termasuk dalam kategori sedang, indeks keseragaman sedang dan dominansi rendah.

Abstract

The retail industry has undergone a significant transformation. Jumbo Mart is one of the retail businesses that consistently meet customer needs in Pekanbaru city. The number of similar businesses makes Jumbo Mart need to have a competitive advantage to compete. One of them is by improving the shopping experience, especially in the aspect of goods layout. However, based on observations and interviews, the determination of the layout of goods at Jumbo Mart is still not optimal. The number of products and variety of items sold is one of the reasons. In addition, customer transaction history has not been used further and is only stored as an archive of monthly reports. Whereas analyzing the data can be an effective solution in arranging the layout of goods based on customer behavior. Therefore, this research proposes a data mining technique with the FP-Growth algorithm to find association rules between categories of goods. The implementation results with a minimum support value of 15% and confidence of 50% get 7 association rules, but only 6 are proven valid. The valid association rules are then proposed to be placed close together so that it can make it easier for buyers to find the desired items. In addition, items with the consumption category are dominant as consequents, which can be found in the four association rules. This indicates that items with consumption categories have great appeal and are an important part of customers' shopping behavior and habits.
