Organisasi menyimpan rekaman aktivitas proses bisnis yang terjadi pada proses di lapangan dalam log data dengan berbagai format. Rekaman aktivitas ini disimpan dalam rangka menghasilkan sebuah model proses bisnis berdasarkan aktivitas pengguna pada proses nyata di lapangan. Dari proses model yang dihasilkan dapat dilakukan analisis tentang kesesuaian antara proses bisnis yang terjadi pada proses nyata di lapangan dengan proses bisnis yang diharapakan oleh organisasi. Analisis ini disebut sebagai conformance checking yang bertujuan untuk mendeteksi deviasi yang terjadi antara proses bisnis yang diharapkan dengan proses bisnis dari proses nyata di lapangan dan sebaliknya. Suatu proses bisnis dikatakan sudah sesuai dengan regulasi (compliant) apabila tidak ada deviasi/nonconformance dalam eksekusinya dari proses bisnis yang telah didefinisikan mengikuti standar.

Al-Qur’an is a scripture which contains the saying of Allah Subhanahu Wa Ta’aala and was revealed to Prophet Muhammad. The 30th juz is the juz that exists in the Al-Qur’an. When studying how to read Al-Qur’an well, the first thing that is learned is reading and memorizing surahs in the 30th juz. Nevertheless, there is a problem in remembering or knowing the surah name and the verse which are in the 30th juz. An android application was developed in order to recognize the surah names in the 30th juz by utilizing speech recognition technology to overcome that problem. Markov Model (Markov Chain) algorithm was implemented in this application. This algorithm will process user’s speech and compute probability of the surah name that was spoken. Speech detection testing gave result that the highest accuracy of application in recognizing the speeches was in the environment without noise with the accuracy of 100% in the most ideal distance is 50 cm for male and for female user. Based on the blackbox testing result, all functionalities of the application have functionated well. Control flow testing gave result that the value is 7 which indicates that the code is simple and well written. 87,74% respondents answered, by filling up the questionnaires, that the application is useful in order to make user knows better about the surah names in the 30th juz.

The pandemic that has hit the world has forced us to do learning indirectly or is often referred to as online (Daring). Online teaching and learning process requires some adjustments both on the teacher's side and the student's side. One of the adjustments is the need to seek technology and adaptation using technology. The currently widely used technology is online meeting services, such as the Zoom Meeting application, Google Meet, Video Calling via the Massager application, or other similar applications. To adapt to the technology, teachers at Madrasah Ibtidaiyah Muhammadiyah 01 Pekanbaru strongly desire to deepen ownership of the Zoom application as one of the media used for online learning. This training aims to provide an understanding and hands-on practice of using Zoom Meeting technology to increase learning effectiveness.

Waste products are increasing every day in line with the increasing number of products and people's consumption patterns. Many people do not separate organic and inorganic waste during disposal. One of the reasons is that people cannot distinguish between organic and inorganic waste. Based on these problems, an Internet of Things-based tool was designed that uses NodeMCU ESP8266 as its microcontroller. To distinguish organic and inorganic waste, three sensors are used at once, namely proximity infrared, capacitive and inductive sensors. The data read by this tool then turns on the LED according to the type of trash can. In this study, a trash can was also designed that uses an ultrasonic sensor to detect the height of the garbage. This altitude information is then sent to a website-based monitoring application using a Wi-Fi network and the MQTT protocol. This application is used by cleaners to monitor which trash bins have to be transported. From the test results, the three proximity sensors used succeeded in distinguishing organic and inorganic waste. The recommended distance for the sensor to work optimally is 3 mm. The data obtained by the sorting tool has also been successfully sent to the waste height monitoring application. Officers get notifications on the website, which trash bins must be transported.

Robot pemadam api merupakan robot yang dibuat dengan tujuan memadamkan api pada daerah yang sulit untuk dijangkau manusia. Robot Pemadam Api harus memiliki kemampuan navigasi yang handal dalam menyelesaikan misinya dengan menerapkan metode yang baik. Terdapat beberapa metode navigasi pada Robot Pemadam Api, salah satunya wall tracking. Pada makalah ini dipaparkan penerapan kendali fuzzy logic untuk metode navigasi wall tracking. Dalam proses pengujian terdapat keterlambatan respon pada fuzzy logic, namun dapat diatasi dengan melakukan perhitungan fuzzy logic diluar sub program navigasinya. Dengan cara demikian robot yang menerapkan fuzzy logic untuk wall tracking mencatatkan waktu rata-rata memadamkan api dan kembali ke home sebesar 66,7 detik untuk start di lorong dan 36,5 detik untuk start di ruang 1 pada sampling jarang dan robot mencatatkan waktu 63,4 detik untuk start di lorong dan 34,9 detik untuk start di ruang 1 pada sampling rapat. Catatan waktu tersebut lebih kecil jika dibandingkan dengan robot yang tidak menerapkan fuzzy logic untuk wall tracking yang mencatatkan waktu sebesar 78,1 detik untuk start di lorong dan 44,8 detik untuk start di ruang 1.

The total number of shipments to be sent from 2017 with an average total of 18 million shipments per month until 2018 reaches 24 million per month, while the process the shipping path is still as described and guessing, so couriers often wrong in estimating the fastest route or forgetting to order delivery based on previous couriers which cause the courier to have to turn around and every time the courier turns back then the shipping process becomes ineffective in terms of time, distance and cost. Based on the results of a 2018 study, Held-Karp produced a better route than Iterative Deepening Search in finding a shipping route. Therefore an Android-based application is created and uses the Google Maps API to determine the time, distance, and cost required at each point of delivery, as well as using the Held-Karp algorithm to search for the fastest path based on time, distance and cost. Based on functionality testing the application is estimated to run correctly and per the expected function, then in cyclometric complexity testing, the Held-karp algorithm is categorized in well-written and structured code and high testability because there is no v (G) above 10.

One of the initial approaches to make learning more enjoyable is to know the patterns of social interaction and types of student communication. There are 3 types of social interaction patterns presented in this training, namely interactions between individuals who wish to achieve achievement (Achievement), desire to socialize with their social environment (Affiliation), and desire to power (Power). Teachers can communicate effectively with students if the teacher knows the type of communication used by students. There are 4 types of individual communication types with their environment. Some communicate concretely, spontaneously, intellectually, and sensitively. Community Service activities carried out are training for teachers to recognize the types of student social interactions and types of student communication. The training was carried out by introducing the two instruments that had been made. The training was held for 1 day offline at SMK Taruna Persada Dumai. Based on the feedback provided by the participants, the teacher felt the benefits of the training and was willing to apply the results of the training to students in the classroom.
