Today's technological developments are growing rapidly, but there are still jobs that are done manually and semi-manually. This paper aims to develop a control system to coordinate the work of tools using an electric motor, which is very helpful in the process of cutting onions in large quantities and is more efficient in spending production costs because the tool designed is an automatic onion cutter. This research method begins with the collection of materials and data related to onion cutters, production of onion cutters, and testing of onion cutters. The measurement results of the tool show that every component in the automatic onion cutter works well and optimally; the measurement process is carried out properly and thoroughly. This optimal work result is supported by Arduino Uno. The Arduino Uno microcontroller acts as a tool controller. In the main system, the onion cutter is controlled by the Arduino Uno with the Arduino programming language. This automatic onion cutting system will work when the onion you want to cut has been inserted into a cross-section that has been equipped with an ultrasonic sensor, and then the onion cutting process is carried out. Compared with the manual method, the cutting time is almost the same. It's just that the advantages of slicing with this tool, the resulting slices are relatively more uniform. Besides that, another advantage is that it doesn't hurt the eyes of the onion slicer. So that this tool can be used by small entrepreneurs and onion farmers to increase productivity and the community's economy.

Information systems are the result of rapidly emerging technological developments because human needs as information users of technology are very strong and rapid. Begin with the very rapid growth of computer technology, computers such as smartphones, tablets, notebooks and others are limited in scale. This small computer device must be connected to the Internet so that it can be used properly. And the information system plays its role as a provider of information that computer users want to access when the computer device is linked to the Internet. The information system developed in this paper is the Citizen Data Collection Information System, this system was created using the YII Framework. The YII framework uses the MVC method which makes it easier to develop a Citizen Data Collection Information System. With this Information System, information about the latest condition of the residents can be easily accessed. So that the Kelurahan, Kecamatan, RW, and RT will have the latest information about their residents and easily anticipate if needed. In the development of this system, it has staged such as literature study, observation, interviews, analysis, design, testing, and implementation. The conclusion is that this information system can carry out the desired function when it is implemented.

The condition of COVID-19 has changed the living order of all units. The government and the entire community concentrate on the importance of public safety, with the consequence that funds from different units are allocated to COVID-19 disaster management, including the allocation of educational funds. Procurement for SMK education facilities and infrastructure, previously restricted by training facilities, such as a motorcycle auto-study program (TOSM) of SMKN 1 XI Koto Tarusan-Pesisir Selatan, has been affected by changes in funding from the Ministry of Education and Culture. The absence of learning media and the small number of active teachers from TOSM means that the capacity of TOSM students to fulfill the minimum industry requirements, which is shown by only 16% of SMKN 1 XI Koto Tarusan graduates who can be accepted immediately into the world of work. In a workshop on the design of a motorcycle starter device simulator to solve the problem of incomplete learning media, the implementation team helped develop learning media. This activity took place at SMKN 1 XI Koto Tarusan Pesisir Selatan from 25 to 28 September 2020. There were 10 teachers involved in the course. The production for this operation is 2 motorcycle starter system simulators, which can be used in the teaching and learning process as learning media.
