Abstract:
Traffic density in the Riau Islands area is increasing day by day. Population density that has exceeded this threshold causes congestion on the road which causes losses to people who are carrying out activities. As e-commerce grows rapidly, it becomes a push for e-commerce applications that develop in line with the community's need for online application-based services that operate on smartphones. The application of online application-based transportation services that are growing rapidly. One of the factors of this online application-based transportation service innovation is the growing number of internet services offered by internet service providers and more and more internet users, so that the internet becomes a necessity and lifestyle for the community. This research is a development of previous research in examining the factors that influence public acceptance of online transportation applications using the UTAUT2 research model; the current study uses the Technology Acceptance Model research model. This questionnaire was distributed to 400 respondents to the residents of the Riau Islands using Amos and SPSS. The results of the analysis of transportation application online acceptance in Riau Kepulauan using Technology Acceptance Model were seen from the construct of behavioral intention use to attitude toward using is 100%, actual system use to behavioral intention to use is 94.7%, perceived usefulness to perceived ease of use is 80.3%, attitude toward using to perceived usefulness is 47.6% whereas behavioral intention use to perceived usefulness is not effected as positive.

Abstract:
Along with the development of technology, the film industry continues to increase, this can be seen from the number of films that appear both in cinemas and tv shows. The Internet Movie Database (IMDb) is a website that provides information about films from around the world, including the people involved in the films. Information contained on IMDB such as actor/actress, director, writer, to the soundtrack used. In addition, IMDb is the most popular and trusted source of information for movies, TV, and other celebrity content. In this case, the researcher will conduct research on the film with what title is the most popular among the public by looking at some of the parameters contained in IMDB such as the number on the rating, score, certificate, and votes obtained from the audience. The data used comes from the Kaggle.com website. The data mining method used is the K-Means clustering method. To find out the optimal cluster value, the Davies Bouldin index is used. The K-Means algorithm will group the data based on the centroid. The parameters used for clustering are runtime, IMDB rating, meta score, number of votes, and gross. The results of the study obtained that the average calculation of the highest attributes was 48.74 and the number of clusters formed was 4 clusters. The results of the evaluation using the confusion matrix obtained an accuracy value of 100%.

Abstract:
The world is in an uproar with the Covid-19 pandemic, which has had an impact on society. Various efforts have been made by governments around the world to suppress the spread of the Covid-19 virus. One of the health protocols that have been appealed by the government is social distancing or social restrictions, namely limiting interactions between human beings as long as 1-2 meters. But in reality, there are still many people who ignore social distancing policies. The application of a social distancing detection system can be a solution to this problem. This system aims to detect people who are violating health protocols in the form of social distancing and then issue a voice warning to keep their distance from others to avoid the spread of the Covid-19 virus by using the YOLO-v5 method which is the latest version of YOLO (You Only Look Once). . Processing speed of YOLO-v5 has increased drastically with the fastest speed reaching 140 Frames Per Second (FPS) and has a small size, even having a size of 90% compared to the previous version. The accuracy of human detection using YOLO-v5 from this system reaches 83.28% and the accuracy of social distancing detection reaches 90.8%. From the results of the percentage analysis that has been carried out, it can be concluded that the system that has been created can function well for social distancing detection, but it is difficult to detect if humans are too far from the camera.

Abstract:
Bimbingan merupakan prosedur yang harus dilaksanakan oleh mahasiswa untuk mendapatkan bantuan dan pengawasan dalam menyelesaikan laporan kerja praktik maupun proyek akhir. Kegiatan ini dilakukan dengan cara mengadakan pertemuan antara mahasiswa dan dosen yang bersangkutan. Sebelum itu, mahasiswa menetapkan jadwal bimbingan dengan cara menghubungi dosen melalui media komunikasi. Setelah mengatur jadwal dengan dosen, mahasiswa harus datang tepat waktu sesuai jadwal yang sudah ditentukan. Walaupun jadwal bimbingan sudah ditetapkan, masih terdapat mahasiswa yang datang tidak sesuai jadwal bimbingannya. Hal ini menyebabkan waktu bimbingan terbuang percuma dan mahasiswa lain tidak mendapatkan jadwal, sehingga mahasiswa terkendala dalam menyelesaikan laporannya. Oleh karena itu, dikembangkanlah sebuah aplikasi manajemen antrian bimbingan berbasis android dengan memanfaatkan teknologi location based service (LBS). Aplikasi menggunakan manajemen antrian berdasarkan prioritas dan location based service digunakan untuk mendeteksi mahasiswa di area geofence dosen. Telah dilakukan pengujian terhadap aplikasi yang dibangun menggunakan teknik black box testing, dengan hasil 100% seluruh kebutuhan fungsional berhasil dijalankan. Selain itu, juga dilakukan pengujian menggunakan usability testing dengan hasil rata-rata persentase pengujian sebesar 85,4% responden setuju bahwa aplikasi antrian telah memenuhi kriteria yang ada pada pernyataan kuesioner.

Abstract:
The purpose of this research is to classify the mushroom based on its characteristic to be in an edible class or poisonous one using the Decision Tree Algorithm. The result showed that odor is the most important attribute to classify the mushroom. Mushrooms which have almond and anise odors are edible, while the rest of it, such as pungent, foul, creosote, fishy, spicy, and musty are poisonous which means they can't be eaten. For mushrooms that have no odor, there are some attributes to be checked such as spore-print-color, gill-size, gill-spacing, and population. At first, overfitting happened. To overcome this, the researcher used Random Sampling Techniques until got better accuracy. The most accurate sample is 99,9% using sample 6 or 2000 data.

Abstract:
The heart is a very important part of the body. The main job of the heart is to pump blood to all parts of the body. The heart has a rhythmic beat when it is pumping blood. This rhythm varies according to the health condition of a person. Therefore, it is necessary to have a system to monitor this rhythm change. The most well-known way to detect the rhythm or speed of the heartbeat is by using sensors. This paper implements a sensing device using a heart rate sensor and an IoT device. The heart rate sensor used is the MAX30100 sensor. As the main processing is an ESP-WROOM-32 which is famous for its WIFI and Bluetooth features. All these devices are combined in a sensor box that is embedded in the faceshield. The result is a faceshield capable of monitoring heart rate and sending the data to various connected devices. The experimental results show the instrument's accuracy value of 9.68% compared to the professional Pulse Oximeter used in hospitals.

Abstract:
The accuracy in extracting and summarizing thousands of reviews into several topics is the key in the implementation of data processing and further information. The hotel industry is no exception, where a review is an asset which, when processed, can produce information that will later be used for business expansion and business continuity. This hotel review topic modeling research uses Latent Dirichlet Allocation as a means to summarize the document. Latent Dirichlet Allocation is proven to be effective in the processing of summarizing words and many studies have used this method. The purpose of this research is to get a summary of words that make up a topic that represents the whole review which can produce data for hotel management to maintain their existence in the business and expand by considering the results of modeling the topic.The results showed that the words location, service, hotel, breakfast, resort and beach were the terms that most often appeared among the dominant topics.
