The payment information system is a data processing system that will produce reports every period, which is once a month. The report will then be submitted to the leadership to find out the smoothness of payments for one month. The payment system functions to manage all payment data that is always changing through payment transactions.

Seiring perkembangan zaman dan teknologi yang pesat saat ini, dalamkehidupan sehari-hari manusia tidak pernah lepas dari aktivitasnya untuk berinteraksi dengan peralatan elektronik yang membantu dan mempermudah pekerjaan manusia. Salah satunya adalah brankas otomatis dengan keamanan menggunakan sensor facerecognition dan fingerprint supaya perhiasan dan barang berharga lainnya lebih terjamin keamanannya dengan sistem keamanan ganda pada brankas.   Proyek akhir ini bertujuan untuk mengembangkan sebuah teknologi yang memanfaatkan beberapa macam komponen sensor, dimana komponen sensor tersebut melibatkan sensor getar untuk mengirimkan sms gateway jika brankas berpindah tempat, dan sim800l akan mengirimkan titik kordinat brankas berupa sms gateway. Dan GPS akan melacak keberadaan brankas sesuai titik kordinat tersebut. Buzzer akan berbunyi untuk memberikan tandaatau notifikasi.

Management of school funds in the form of SPP (Educational Development Donations) at the Kranggan foundation sourced from kindergarten, elementary and junior high schools so far is still managed manually, making it difficult and takes a long time for the Administration to check lists for students who have made payments. Every month. In this study, an SPP payment system was made using an SMS Gateway with the web scraping method. In the development process using the prototype method. The researcher aims to develop a web-based information system that is expected to help manage school payment data for the better. The information system will be equipped with an SMS feature that will be sent to the parents of the students concerned so they can know that the school payment has been made. This SMS feature is also useful for sending reports of late payments or SPP arrears to parents of students whose children are late in paying tuition fees. With this program, students can also make tuition payments in two ways. The first is manually or submitting payment to the TU at the school. The second is by means of money transfer payments through banks.

PT Fastronic Makmur Sentosa (FMS) is an Authorized Dealer Smartfren which distributes products from Smartfren, like Staterpack prime, vouchers, modems and handsets doungle bandling. SMS Gateway application as a service functioned to integrate systems between customers with automated information systems, the customer service with the administration in order to obtain valid information. Customers can order products and access information easily via SMS without having to come directly to the PT. FMS information regarding pricing, promotion information, product specifications and ordering products for customers who are already registered. SMS Gateway application can also help customer service in its duty to serve customers with data that is clear and ter updates can be seen in the administration module. With the SMS Gateway Application to deliver information more quickly when customers need information, generate reports on the stock with a clear to the administration

Hydroponics are now increasingly in demand, should be checked regularly so that hydroponic plants thrive. Likewise, in Siliwangi Indah Hydroponics Semarang, which still uses manual methods, namely the absence of a device that detects nutrient water temperature and pH automatically and the absence of tools that can normalize nutrients automatically. Arduino Uno R3 can be used to detect temperature automatically with a temperature sensor DS18B20, and detect pH with a pH sensor. Then the sensor readings are sent to the farmer's cellphone with SMS Gateway. The sensor readings are also used to divert the flow of nutrients from the spare reservoir, so that the nutrients remain normal. So this tool can automatically measure the nutrient water temperature and pH and replace the main nutrients to the reserve nutrients. And the assessment obtained from experts on this tool gets a value of 3.6 and from the expert gets a value of 3.7. Hydroponic nutrition in this study is maintained normally and farmers always know the nutritional state. So that the hydroponic plants thrive and have maximum yields.

Guava is a fruit plant with various benefits for humans. Both the leaves and the fruit can be used to treat various diseases. As an example of the fruit to treat Dengue Hemorrhagic Fever, Tyfus, and so forth. The leaves can be used as traditional medicine to treat cough and diarrhea. In the highlands it is indeed cold and there is little possibility of plantation fires. However, fires can occur as a result of human activity both intentional and unintentional. The location of the plantation land that is relatively far from the residential population makes fires sometimes known too late. Therefore, it is necessary to create a tool to monitor the temperature and concentration of guava plantation smoke from a distance every day so that if the temperature or the density of smoke reaches a certain number that indicates the occurrence of fire then the tool will immediately send a notification via SMS to the plantation owner. In addition, the tool will immediately pour water from the reservoir or water reservoir into the guava plantation. In the water reservoir there is a tool to detect the volume of water. The device to be created uses the LM35 temperature sensor, MQ-2 smoke sensor, HC-SR04 Ultrasonic sensor, Relay, Arduino Uno R3 microcontroller and GPRS Shield along with the GSMSIM Card.
