Every object is always moving, and movement of an object can occur at any time. The value of the motion which produced from an object can be very small to very large, and the impact of the movement can be at risk until very risky. For this reason, the movement of objects at risk must be observed whenever changes and observations for data retrieval can be done remotely. The purpose of this research to design an Internet of Things (IoT) devices that can observe and detect changes in the motion of an object. The device is designed to be small, around 44 x 48 millimeters with very low power consumption. The design phase begins with recording motion data using the MPU6050 accelerometer sensor as a motion detector, arduino nano as a control device, WiFi ESP8266 as a communication medium for sending data from a receiver apllication motion data with UDP protocol. The test results show that this device is very sensitive to detect changes in the motion and angle of X, Y and Z of an object.

One of the education problems in this country is the zoning policy in the new student admission system (PPDB). This is in accordance with the policy of the Ministry of Education and Culture (Kemendikbud) in 2016 which began with the use of zoning for the administration of national exams. Then in 2017 the zoning system was implemented for the first time in implementing PPDB, and was refined in 2018 through Permendikbud Number 14 of 2018. The first problem faced is the zoning system organized by State Junior High Schools in Medan and the Education Office which still causes unrest for the community, especially parents, where the implementation has not been carried out in a transparent manner, both the number of prospective students who have registered at the school and the scoring system based on distance, the achievement of prospective students and the transfer of parents' duties. The second problem is the system for announcing the acceptance of prospective students who have passed a certain school is not generally published. The solution offered to deal with problems that occur to partners is by transferring science and technology in the form of management information system-based applications and services to partners in the form of a new student admission information system (PPDB), training related to the use of the PPDB system, and assistance to partners. . The result of this community service program is to increase insight and knowledge of skills for partners in optimizing the use of information systems and information technology to support PPDB operational activities, improving partners' skills and abilities in using school service management applications designed to facilitate the school PPDB process and implementation of PPDB. which is organized by schools and education offices to become more transparent to the public.

Most of the people in the Bagan area, Percut Sei Tuan Subdistrict, North Sumatra, are mostly fishermen, almost 80% of the people work as fishermen, which is done by the head of the household in the area. The Bagan area of Percut Sei Tuan District has a lot of catches of trash fish that are only thrown away by fishermen, even though the trash fish has a high protein content and can be processed into processed food such as brains, peanut butter and so on which can improve the economy of the people in Bagan. . The large number of trash fish caught by fishermen and not being utilized optimally resulted in the garbage fish only becoming waste and causing odors and diseases around the fishing community settlements in Bagan Percut, the inability of the community to turn the trash fish into processed food and be worth selling it resulted in an economic level. The fishing community has not increased, with training on how to make processed food from trash fish, training on good and proper packaging and marketing training using internet media, it is hoped that in the future fishermen families can improve their economic level for the better.

Small and Medium Enterprises have a big enough role for the welfare of society. This sector is able to absorb a large enough workforce and provide opportunities for SMEs to develop and compete with companies that tend to use large capital (capital intensive). The purpose of this activity is to improve aspects of marketing management that have an impact on increasing sales. The object of this activity is the clay pottery ceramics business in Wonosari Village, Tanjung Morawa District, Deli Serdang Regency. The main problem for partners is that partners do not focus too much on marketing management, relying more on conventional marketing systems such as ordering goods, safekeeping at the nearest store, and selling in their own stores whose position is not too strategic, causing stagnant product sales. The proposed solution is to apply management and marketing techniques for partner products using internet media such as websites and social media. The output targets of this partnership program are: 1) increasing understanding of the importance of technology to business; 2) capacity building in internet technology management; 3) increase in market absorption; 4) Improved communication skills for partners in managing websites and Social Media Marketing, namely the ability of partners to communicate products and product brands so that they have a list of regular customers on the website who have the potential to purchase products on an ongoing basis; 5) increase in partner sales turnover.

The development of technology today, especially computer technology has been very advanced. Including in Indonesia have many computer products that are marketed with various types, prices and specifications. To address it then we as consumers should be careful in choosing and buying the hardware components. So we are not deceived by the cheap price offered but also must be more thorough on the quality of goods offered. In general, the solution if the consumer experiencing performance problems in the software is to install the computer on the computer service. Installation costs generally range from RP 50,000 - RP 75,000. Imagine if the consumer in a year to install 5 times, the cost incurred around RP 250,000 - RP 375,000. Though the computer installation process is very easy to learn and just need accuracy in the process of data format. Hardware and operating system specifications are still not realized by the public is the most important part in the performance of a computer. Knowledge of hardware specifications is crucial to the performance of a hardware, as well as operating systems that do not have viruses or malware can also improve computer performance. Based on that, direct exposure and practice will be given maximally to provide the required information

Kemacetan adalah situasi atau keadaan tersendatnya atau bahkan terhentinya lalu lintas yang disebabkan oleh banyaknya jumlah kendaraan melebihi kapasitas jalan. Dampak dari kemacetan ini mengakibatkan pemborosan waktu, pemborosan bahan bakar, polusi udara, tingginya tingkat stress pengguna jalan, tingginya tingkat kecelakaan dan sebagainya. Kemacetan banyak terjadi di kota – kota besar, terutamanya yang tidak mempunyai transportasi publik yang baik atau memadai ataupun juga tidak seimbangnya kebutuhan jalan dengan kepadatan penduduk. Kemacetan lalu lintas menjadi permasalahan sehari – hari terutama di kota medan. Di kota medan sendiri, waktu terjadinya kemacetan secara umum dapat dibagi menjadi tiga waktu yaitu pagi (06.30 – 08.30), siang (12.00 – 13.30) dan sore (16.00 – 19.00). Dalam mengantisipasi permasalahan tersebut maka pada jurnal ini diusulkan berupa solusi dengan memilih jenis kendaraan misalnya : sepeda motor, mobil pribadi, angkot dan taksi dengan taksiran waktu tempuh yang bersesuaian dengan jenis kendaraan yang dipilih. Dalam proses pemilihan jenis kendaraan ini diterapkan fuzy linier programming untuk memberikan pemilihan yang optimal dalam mengantisipasi kemacetan yang terjadi. Hasil akhir dari penelitian ini diperoleh beberapa jenis kendaraan yang terbaik untuk mengatasi waktu kemacetan yang terjadi.

Of the several animals that we know, the cat is one of the most popular pets in today's society. However, in order to keep the pet cat in good health, cat keeper must pay more attention to the food schedule otherwise the cat will be susceptible to disease, so it can harm the cat itself. In today's modern era, many things can be designed to make activities easier. One of them is the design of a prototype automatic cat feeder. The purpose of this research is to design and make an automatic cat feeding device using Arduino Uno R3 as the brain in this series which then uses Arduino IDE software and C++ programming discussion to input the data that will be needed. Furthermore, this tool will also be directly connected to the RTC (Real Time Clock) as a benchmark for the hour and date and the servo motor as a valve controller, so that the feeder will open according to the input schedule. This tool also uses the GPRS Shield 800L as a sender of SMS notifications when the prediction feed is running out. Finally, this one set of tools also uses a step down module which can be used as a voltage adjustment for the feeder. This tool can later be useful, especially for cat shelter owners/keepers because it can provide feed according to a time and schedule whose own dose can be inputted based on age. The advantage of this tool is that it can last for approximately 2 hours without electricity (possibly when the power goes out) specifically for sending notifications.
