Abstract

Sentiment analysis on social media is becoming an important approach in understanding public opinion towards an event. Twitter, as a microblogging platform, generates a large amount of data that can be utilized for this analysis. This study aims to evaluate and compare the performance of three classification algorithms, namely Support Vector Machine (SVM), Random Forest, and Extreme Gradient Boosting (XGBoost), in sentiment analysis related to the Clash of Champions event in Indonesia. To represent the text data, two feature extraction techniques are used, namely Term Frequency-Inverse Document Frequency (TF-IDF) and Bag of Words (BoW). In addition, Synthetic Minority Over-sampling Technique (SMOTE) is applied to handle data imbalance, while model optimization is performed using GridSearchCV. The research dataset consists of 1,000 tweets collected through web scraping, then manually processed and labeled before model training and testing. The results showed that the TF-IDF technique provided superior results compared to BoW. The Random Forest model with TF-IDF achieved the highest accuracy of 91%, while XGBoost with TF-IDF had the highest Area Under the Curve (AUC) of 0.91. The findings confirm that the selection of appropriate feature extraction techniques and algorithms can improve accuracy in sentiment analysis. This study can be applied in public opinion monitoring and data-driven decision-making. Future research can explore word embedding techniques and transformer-based deep learning models to improve semantic understanding and accuracy of sentiment analysis.

Abstract

Pembuangan sampah secara open dumping telah banyak memberikan dampak negatif bagi lingkungan seperti terkontaminasinya air tanah oleh lindi. Interpretasi sebaran lindi di sekitar TPA Salatiga Kabupaten Sambas telah dilakukan menggunakan metode self-potential. Penelitian ini menerapkan 8 buah lintasan dengan panjang masing-masing 150 m, jarak antar lintasan 10 m, dan jarak antar titik porous pot pada lintasan berjarak 10 m. Pengambilan data nilai potensial di lokasi penelitian dilakukan pada 120 titik pengukuran. Hasil pengukuran diperoleh variasi nilai potensial sebelum dilakukan koreksi sebesar -3,18 mV hingga 5,42 mV. Sedangkan variasi nilai potensial setelah dilakukan koreksi bernilai -7,98 mV hingga 6,36 mV. Sebaran lindi bawah permukaan diduga terakumulasi pada area dengan nilai potensial yang relatif lebih kecil dan bernilai negatif. Hasil interpretasi menunjukkan bahwa sebaran lindi mengalir dari arah barat dan terakumulasi pada arah timur hingga timur laut lokasi penelitian.

Abstract

Acoustic materials such as plastic carpet, gypsum board, styrofoam and plywood can be used to reduce sound intensity. Nevertheless, the existing research has generally focused on single-ingredient studies. In this research, the optimum thickness of each material will be sought based on its efficiency in reducing the sound intensity level. Besides that, the efficiency of various types of materials will also be tested for reducing the level of sound intensity. In this study, a resonator tube was used in making measurements. Acoustic materials used as test materials, both single materials and combined materials, can be placed in the resonator tube. The distance between the sound source and the detector is 30 cm, with the position of the detector right behind the acoustic material. Tests on a single material show that the measured sound intensity level decreases in proportion to the thickness of the acoustic material, with styrofoam has the lowest efficiency. Meanwhile, the combined material that combines plastic carpet material at a frequency of 2000 Hz has an efficiency value that tends to be higher than the combination of materials without carpet with efficiency >30%. However, at a frequency of 1500 Hz, all combined materials have efficiency values that are not significantly different. All models of material combinations are proven to be able to reduce sound intensity levels compared to single materials. Thus, it can be concluded that the combined material has the potential as an efficient acoustic material.

Abstract

Salah satu parameter dalam penyaluran energi listrik adalah mutu dan kehandalan yang harus memenuhi standar. Pada praktiknya, Perusahaan Listrik Negara (PLN) akan terus memperbaiki dan meningkatkan mutu dan kehandalan jaringan listrik guna memberikan pelayanan terbaik bagi setiap pelanggan. Langkah yang diambil salah satunya yang dilakukan oleh Unit Layanan Pelanggan (ULP) Panton Labu, yaitu dengan membangun jaringan baru agar dapat melayani beban yang semakin meningkat. Pembangunan jaringan baru dilakukan supaya dapat memperbaiki tegangan sistem melalui pembagian beban penyulang serta meningkatkan kehandalan dalam mempermudah manuver ketika terjadi gangguan. Kondisi kelistrikan ULP. Panton Labu disuplai dari Gardu Induk (GI) Panton Labu terdiri dari 2 Trafo Daya (TD) yang masing masing berkapasitas 30 MVA. Beban puncak GI. Panton Labu adalah sebesar 14,5 MW untuk TD 1 dan 6,5 MW untuk TD 2. GI. Panton Labu salah satunya mensuplai Gardu Hubung (GH) Panton Labu melalui penyulang PL 05. Namun, sebelumnya hanya terdapat 1 incoming yang masuk ke GH. Panton Labu, padahal pada TD 2 GI. Panton Labu masih terdapat 3 kubikel cadangan (spare) yang belum termanfaatkan dan juga pada kubikel di GH. Panton Labu sudah terdapat couple bus dan 1 kubikel cadangan. Hal ini disebabkan karena belum adanya jaringan express feeder yang menyuplai dari GI. Panton Labu ke GH. Panton Labu sehingga apabila terjadi gangguan pada suplai utama penyulang PL 05 maka akan terjadi padam diseluruh kubikel GH. Panton Labu. Tujuan dari penelitian ini yaitu untuk mendapatkan nilai SAIDI dan SAIFI sebelum dan setelah pembangunan express  feeder SUTM A3CS 3x240 mm2 sebagai incoming baru. Hasilnya, Mutu tegangan pada GH Panton Labu sebelumnya sebesar 20,4 kVterjadi perbaikan menjadi 20,7 kV. Rekonfigurasi express feeder SUTM 3x240 mm2 sebagai incoming baru dapat mengurangi durasi padam dengan indeks keandalan rata rata nilai SAIDI pada ULP. Panton Labu turun dari 12,558 menit/pelanggan menjadi 6,205 menit/pelanggan. One of the parameters in the distribution of electrical energy is the quality and reliability that must meet the standards. In practice, the State Electricity Company (PLN) will continue to improve and increase the quality and reliability of the electricity network to provide the best service for each customer. One of the steps the Panton Labu Customer Service Unit (ULP) takes is to build a new network to serve the increasing load. The construction of a new network is carried out to improve the system voltage by sharing the feeder load and increasing reliability in facilitating maneuvers when disturbances occur. ULP electrical conditions. Panton Pumpkin is supplied from the Panton Pumpkin Substation (GI) consisting of 2 Power Transformers (TD), each with a capacity of 30 MVA. GI peak load. Panton Pumpkin is 14.5 MW for TD 1 and 6.5 MW for TD 2. GI. One is Panton Labu supplying the Panton Labu Switching Station (GH) via a PL 05 feeder. However, previously there was only 1 incoming to GH. Panton Pumpkin, even though at TD 2 GI. Panton Pumpkin still has 3 spare cubicles that have not been utilized and also in cubicles at GH. Panton Pumpkin already has a couple of buses and 1 extra cubicle. This is because there is no express feeder network that supplies from GI. Panton Pumpkin to GH. Panton Pumpkin so that if there is a disturbance to the main supply of the PL 05 feeder, there will be blackouts throughout the GH cubicles. Pumpkin Pantone. The purpose of this study is to obtain SAIDI and SAIFI values before and after the construction of the A3CS A3CS 3x240 mm2 express feeder as a new incoming. As a result, the voltage quality at the previous Panton Pumpkin GH was 20.4 kV, an improvement became 20.7 kV. Reconfiguring the SUTM 3x240 mm2 express feeder as a new incoming can reduce the blackout duration with the reliability index of the average SAIDI value on the ULP. Panton Pumpkin decreased from 12,558 minutes/subscriber to 6,205 minutes/subscriber..
