Dam is a construction that is built to restrain rate of water into a reservoir, lake, or recreation area. Often dams are also used to drain water to a hydroelectric power plant. Most dams also have a section called the water gate to remove unwanted water gradually or continuously. Based on the existing problems, the author analyzes and designs a new system that anticipates weaknesses in the running system without causing new problems. The automatic control system for water discharge in the dam simulation uses the ATMEGA 32 microcontroller and the serial communication that the author proposes has answered the problems that arise. The automatic control system for water discharge in the dam simulation using the ATMEGA 32 microcontroller and serial communication can give good results in providing water level data in the aquarium container tested. The software used as a tool in this research is Borland Delphi7 and Arduino and the methodology used for the development of this application is the Spiral method. The results of the development of this system are expected to make it easier for the government to fix waterways.

Sentiment analysis refers to Natural Language Processing techniques that are classified as Unsupervised Learning to identify positive, negative, or neutral opinions. Many of these opinions come through Twitter, because social media is quite effective and efficient in commenting because it can only write a maximum of 140 characters. From previous research, the value of the accuracy of the sentiment analysis carried out by one of the NLP libraries, namely TextBlob, has shown that Unsupervised Learning does not produce such good scores. With the Telkomsel service case study the writer took the dataset from Twitter and the results of the analysis with TextBlob only showed a value of 58.59%. Optimization is done by adding the Support Vector Machine method which is included in the Supervised Learning category. The best results obtained from this study are values that show 75%.

In this research is done to know balance the position of Access Point on Wi-Fi network in Sekolah Tinggi Teknologi Indonesia Tanjungpinang campus. The power of existing Wi-Fi network is not optimal in serving the entire area, so it needs to balance Access Point to get best signal quality. Network performance analysis is done by measuring the signal strength and coverage area of access point using netspot software, inSSIDer and Wireless Wizard. The netspot software is used to determine the coverage area of the access point, while the inSSIDer and Wireless Wizard software is used for wireless signal monitoring and positioning of access points for the best signal reception in the research area. From the measurement results, calculations and analysis obtained, the number of access points needed to cover an area is determined by the type of access point used. When viewed from the access point identified in the measurement area of the placement position of the access point, distance is not the only determinant of the best signal received by the user, the construction of the building made of the wall and the obstacle factors also affect the signal quality of the access point used.

Kemajuan teknologi di era globalisasi sekarang ini sudah semakin pesat. Salah satu contoh hasil dari berkembangnya teknologi adalah komputer, yaitu sebuah perangkat elektronik untuk memanipulasi data yang cepat dan tepat serta dirancang dan diorganisasikan supaya secara otomatis menerima dan meyimpan data input, memprosesnya dan menghasilkan output dengan menggunakan suatu program yang tersimpan di memori komputer. Mikrokontroler merupakan sistem komputer yang seluruh atau sebagian besar elemenya dikemas dalam satu keping tunggal (chip) IC. Oleh karena itu, mikrokontroler sering disebut single chip microcomputer. Mikrokontroler biasanya dikelompokan dalam satu keluarga yang mempunyai bebrapa varian. Setiap varian mikrokontroler memiliki karakteristik yang berbeda-beda sesuai dengan penggunaanya, tetapi masih tetap saling mendukung dalam pemrograman (kompatibel). Tiap varian mempunyai perbedaan antara lain pada kapasitas memori RAM sebagai penampung data olahan dan memori flash PEROM sebagai penampung kode-kode program atau intruksi. Mikrokontroler tersusun dalam satu chip dimana prosesor, memori, dan I/O terintegrasi menjadi satu kesatuan kontrol sistem sehingga mikrokontroler dapat dikatakan sebagai computer mini yang dapat bekerja secara inovatif sesuai dengan kebutuhan sistem. Sistem ini dirancang dengan menggunakan RFID modul sebagai validasi member/user untuk memudahkan user dan penjaga studio musik, dan Arduino uno sebagai pusat kendali. Ketika user akan melakukan rental studio musik maka user harus memiliki RFID card, dan apabila waktu rental akan habis makan lampu pemberitahuan akan mati menandakan waktu rental telah habis, apabila user masih memiliki sisa waktu maka user dapat melakukan penyimpanan waktu rental.
