The Healthy living community movement as known as GERMAS is a systematic and planned program that symergized with several ministries and institution. This program aims to increase people’s willingness and awareness to adopt a clean and healthy lifestyle and behavior, such as : physical activity, consuming fruits, and vegetables, and also regularly check up. This program (community service) was carried out in kota tangerang selatan, attended by 200 participants from various elements of the surrounding community, and reached an agreement to commit to healthy living, one of which was signing a healhy living commitment.

Seiring dengan perkembangan zaman khususnya di Indonesia mulai kehilangan sedikit demi sedikit lahan sebagai media tanam. Salah satu cara untuk mengatasi masalah tersebut adalah dengan bercocok tanam dengan media hidroponik. Salah satu sayuran yang menggunakan media tanam hidroponik adalah sayuran sawi caisim. Permasalahan yang dihadapi petani hidroponik sawi caisim adalah penyediaan nutrisi yang cukup bagi tanaman. Tingkat kepekatan nutrisi yang dibutuhkan tanaman sawi caisim adalah 840-1400 PPM, apabila tanaman kekurangan unsur hara maka menyebabkan tanaman berkurang dalam melakukan penyerapan air dan ion nutrisi pada akar tanaman. Selanjutnya sawi dapat tumbuh dengan baik pada suhu rata-rata 15-30?C dan apabila suhu terlalu tinggi dapat menyebabkan tanaman mudah layu atau bahkan mati. Berdasarkan permasalahan yang telah diuraikan di atas, maka penulis membuat “Sistem Monitoring Suhu, Kelembaban dan Kandungan Nutrisi Budidaya Tanaman Sawi Caisim Hidroponik Berbasis IoT". Penelitian ini bertujuan untuk mengembangkan sistem yang dapat memantau suhu dan kelembaban dengan menggunakan sensor DHT11, kandungan nutrisi menggunakan sensor TDS Meter dan mikrokontroller Wemos D1 R1. Data pemantauan sensor akan ditampilkan menggunakan android dengan memanfaatkan teknologi Internet of Things.

Starting from the development of medical technology that is increasingly sophisticated and rapidly growing,researchers conduct medical research, namely about patient infusion handling services. In handling patient infusion, currently it is still manual which is carried out by nurses / medical personnel. Infusion handling services for patients still have shortcomings, namely the process of monitoring and replacing infusion fluids which are often late. If the problem is not treated quickly, it can lead to problems, namely the presence of air embolism in the blood vessels (the entry of foreign objects into the blood vessels, for example air). From that problem, the researchers made a new innovation in medical technology in handling infusions automatically and based on IoT. In this study, the smart online infusion device that has been made has good features and is very effective in handling infusions. This device has 3 main functions, namely: it can monitor the remaining infusion, it can change the infusion fluid automatically and it can indicate a blocked patient's infusion. This device already has a method for processing data with fuzzy logic. Media monitoring has been supported by a website that can be controlled remotely and in real time. Tests have been carried out and the effectiveness of the system is found to have an error rate of 0.2% - 0.7% and has an accuracy of 98%. Thus this tool can be used in terms of handling patient infusion automatically.

The development of microcontroller technology that is rapidly making applications to be developed as a work in the field of technology that can help and facilitate human activities. Researchers see that current technological developments there are many uses of loadcell sensors to detect weight on objects. The number of factors that affect the weight difference between digital scales and scales very significant conventional. Therefore researchers analyzed the use of loadcell sensors for calculate solid and liquid objects and analyze the work system and the accuracy of the accuracy on the loadcell sensor in calculating the weight of solid objects and liquid objects.

n this digital era and the increasingly developing human resources, it is possible to create new research in this era of development. One example of its development is the discussion of the concept of serial communication. In technology, we know the name of the serial communication. In today's world serial communication is the forerunner of communication between platforms in general. In this journal we will know what serial communication is, it is a communication method that is carried out one way and the concept of sending data is bit by bit or, in other words serial communication is one method of data communication that is sent over a cable which gets one bit of data in a a certain time simultaneously and alternately. In this study using the main tool namely the HC-05 bluethoot module which is used as a master and slave.

Abstract The more developed human needs about technology, the more research will be conducted on increasingly rapid technological developments, one example is IoT or Internet of things. It cannot be denied that IoT is a future technology that will be widely used by humans, because IoT has a concept that aims to expand the benefits of internet connectivity that is continuously connected. Allows humans to easily communicate with all equipment connected to the internet network. For this reason, the researcher developed a research on the concept of data communication between devices and interfaces. In this study the website uses wireless which is connected to the internet network. This wireless device will use the ESP8266 wireless module that has been embedded in the Wemos D1 R1 Mini.
