Abstract

Activities such as planting and gardening become one of prominent hobbies. An issue of having such well grown plants is the impractical and unachieavable task to monitor 24 hours a day, thus we need a smart gardening system that can monitor the garden on demand. One of the problems in residential gardening systems is how to water the plants while the owner is not at home. Some of people have an adequate knowledge of using IoT to make their life easier. This paper proposes a simple automatic gardening system in watering several plants as programmed. In addition, this system allows human’s manual intervention either locally or remotely via Internet, to control a water pump. To build this smart gardening system, we use Xiaomi home application from Google Play. In this application, we can set the program to water the plants daily with definite time periodic independently.

Abstract

Nowadays, security and gardening systems in densely populated residential areas are generally done manually. The security system in housing sometimes places security posts at street corners that are some distance from citizen’s homes thus they cannot be monitored at all times. Whereas other problem of watering system in citizen’s homes, someone has to water the plants one by one that it is not efficient in  energy, time and water availability thus that it can reduce the quality of the plants. Internet of Things (IoT) is a concept and method for remote control, monitoring, and various tasks. IoT is connected to a network that it can be accessed anywhere which can make things easier. IoT can be used to solve various problems. One of them is security issues and gardening activities. By using smart home technology, the security system is carried out by placing CCTV (Closed Circuit Television) which can be accessed by the home owner, anytime and anywhere the home owner is located. On the other hand, gardening is one of the most popular hobbies. In this field, IoT can be used to monitor and regulate various things to support gardening activities. In this community service activity, we are proposed a simple automatic gardening system for watering some plants programmatically in Pondok Hijau Indah residence. The system also allows manual human intervention either locally or remotely via the internet to control CCTV and water pumps. To build this smart Home system we will use the Xiaomi Home application from Google Play. In this application, we can set a program to control CCTV and water the plants every day at a certain time periodically, in this case, we set every 7 hours to watering the plants.

Abstract

In this study, a rakaat counter tool was designed and implemented to reduce mistakes in calculating the number of rakaat during prayer. The piezoelectric is used as sensor which is placed on the top of the prayer mat. Rakaat is calculated when piezoelectric has detected twice prostration. There are four modes in this system, namely fardhu prayer with seven segment display, fardhu prayer with  LED display, sunnah prayer with seven segment display, and sunnah prayer with  LED display.. There is an LED indicator when the rakaat is done which should be in accordance with the prayer time using RTC. The first test of this tool was carried out with piezoelectric calibration when pressed by the load and forehead. This was accomplished to determine when piezoelectric counting proceeded as piezoelectric was connected directly to the ADC of Arduino Uno. The second test was carried out by testing the tool to be used for 3 days in 5 fardhu prayers and 1 sunnah prayer. From the results of the testing it is proven that this tool works properly, and piezoelectric can be used as a replacement button as a tool for rakaat counter.

Abstract

The waste problem is a very complex discussion. Every day thousands of tons of waste are produced by industry and households. The most complicated problem of handling waste today is plastic. Until now, Indonesia is the number two plastic waste-producing country in the world, amounting to 187.2 million tons/year (2015). This problem needs to be solved scientifically, given the pollution generated by plastic waste is getting worse. One of the efforts made is to recycle plastic waste, such as the people of Cinanjung Village, Kutawaringin Village, and Hegarmanah Village, Tanjungsari District, Sumedang Regency. The problems that arise are (1) the process of making "butek" (plastic seeds) is still very traditional which endangers the safety of the craftsman and the surrounding environment, (2) the process of making plastic seeds requires a long time, (3) the production management system is managed simply. The solution offered is designing and making Plastic Lubricating Machines as well as management and technical training in the use of lubricating machines. From the use of the lubricating machine it can be concluded that; (1) the production process is efficient and effective, (2) occupational health and safety are concerned, (3) the quality of the product is better, (4) production management is organized and recorded.
