Ulu apad adalah system pembagian tugas dalam melaksanakan ayah-ayahan (tugas-tugas) adat yang dipergunakan di Desa Pakraman Katung, Kintamani, Bangli. Beberapa kesinoman menjadi pengatur pelaksanaan ulu apad tersebut. Kesinoman biasanya memberikan informasi kepada orang yang mendapatkan tugas-tugas tertentu. Kesinoman juga mencatat orang-orang yang tidak hadir dalam sebuah petedunan. Kesinoman juga harus memungut denda yang harus dibayar oleh orang-orang yang tidak melaksanakan kewajiban adatnya. Dalam melaksanakan tugasnya, kesinoman menggunakan kertas dalam mencatat setiap aktifitasnya. Dalam memberikan informasi kepada para warga, kesinoman sudah menggunakan teknologi, seperti telepon, sms, ataupun aplikasi chating seperti Whatsapp maupun BBM. Melihat sebaran penggunaan perangkat pintar semakin banyak di warga desa Katung, alangkah baiknya jika pekerjaan kesinoman dirangkai kedalam sebuah system informasi berbasis perangkat pintar yaitu handphone dengan system operasi android. Melalui system ini, kesinoman bisa memberikan informasi kepada para warga melalui handphone, dan para warga juga bisa melihat pengumuman pada handphone mereka. Para warga bisa memberikan verifikasi (datang/tidak) ke sebuah tugas. Kesinoman juga langsung memiliki rekapan denda yang harus dibayarkan oleh masing-masing warga di perangkat handphonenya. Dengan system ini, system ulu apad akan mengikuti tren teknologi tanpa menghilangkan makna adat istiadat yang ada di desa Katung tersebut. Kata kunci : Android, ulu apad, kesinoman, desa katung

The negligence of residents and the lack of a house security system are the causes of the rampant cases of theft. Technological developments are increasingly rapid, making technology can be applied as a security system at home. This can be a solution to these problems. In this study a home security system was developed in the form of a prototype. This study uses a microcontroller that can be controlled using mobile devices via bluetooth communication. The prototype consists of a keypad to enter a password as a substitute for a home key, a PIR sensor as a detection of human body heat movements, and a buzzer as an alarm. The results of this study are that the prototype has been realized where the servo motor has been able to open and lock by entering the correct password. Setting ON / OFF lighting, display information on the LCD, and ON / OFF PIR sensor from an Android mobile phone via Bluetooth communication are in accordance with the plan.

The development of electric vehicles in Indonesia began in 1997 by the IndonesianInstitute of Sciences (LIPI) but since 2013 has slowed down. Presidential Regulation 55/2019strengthens the development of electric vehicles in Indonesia which followed by severalsupporting regulations. Currently, the development of electric vehicles, both in terms of researchand industry or commercial products, is getting better. This paper reviews the current status ofelectric bicycles and electric motorcycles in Indonesia which are commercially available. Theresearch was conducted by through online survey during 2020-2021 which produced adatabase of electric bicycles/motorcycles. Currently, there are 64 electric bicycles and 44electric motorcycles. These vehicles use either two or three wheels with electric drive capacitybetween 180 W to 4200 W. The most common electric motor used is BLDC at 87%. The electricbike/motorcycle has speed ranges between 20 km/h to 70 km/h with battery capacity of 5,2 Ahto 70 Ah with milage ranging from 15 km to 200 km. The information presented will helpstakeholders to get a quick overview of the development of electric bicycles/motorcycles in thecountry and serves as benchmark for developing electric bicycles or motor to meet domesticneeds.

Embedded systems play a very important role in various fields so that several universities,especially Udayana University in the Electrical Engineering Study Program, Faculty ofEngineering have included embedded systems + lab courses. However, the availability ofsupporting facilities for activities in the lab is not yet available as it should be. Based on this, inthis research, a practicum module for an embedded system based on Raspberry Pi will bedesigned and made (Module 2: implementation of a simple system). This practicum module hasthree experiments, namely a lamp control system and a 5 V DC motor equipped with an LDRsensor (experiment 1); monitoring the water level using the HC-SR04 sensor module and theheight data is displayed on a 16 x 2 LCD (experiment 2); Human movement detection uses theHC-SR501 sensor module with output in the form of audio that is channeled to the speaker, theimage display by the 0.96 inch OLED module, and the rotation of the LDR servo shaft(experiment 3). The results obtained in the three experiments are that all systems worksuccessfully with the following conditions: The load on the relay turns on when the LDR sensorcondition is covered with black cloth, the load on the relay goes out when the LDR sensorcondition is left unobstructed and the LDR sensor is illuminated by an LED flashlight. The LEDindicator lights up according to the condition of the water level reading by the HC-SR04 sensormodule. The HC-SR501 sensor module successfully detects the movement of objects in theform of humans at a distance of 1 m, 1.5 m, and 3 m.

Most of desktop-scale 3D printers are based on the open-source design of the ReplicatingRapid Prototyper (REPRAP) community. One aspect that can be developed in REPRAP 3Dprinters is the addition of Internet of Things (IoT) technology. Therefore, a Raspberry Pi-based IoTsystem that can be implemented on a REPRAP 3D printer is developed. The IoT system allowsthe 3D Printer to connect into internet network and has a website-based interface. This study aimsto compare the impact of Raspberry Pi based IoT systems implementation on the 3D printingspeed and to measure productivity level of 3D printer operator. Testing is done by printing fourobjects when the IoT system has not been added to the 3D printer and printing four objects whenthe IoT system has been added to the 3D printer. In testing, the data on the printing time of eachobject is obtained, this data is used to compare the print speed between before and after the 3Dprinter was added to the IoT system. Furthermore from testing, the data of time required byoperators to prepare and monitor the performance of 3D printers is also obtained, this data is usedto compare the productivity levels of 3D printer operators before and after adding the IoT system.Based on the test results, it was found that 3D printers with IoT systems have faster printpreparation times than 3D printers without IoT systems. However, 3D printers with IoT systemshave a longer machine time than 3D printers without IoT systems. The operator productivity levelfor 3D printers with IoT systems is higher than 3D printers without IoT systems.

In this journal, an analysis of the NutriNeeds application is carried out. The Nutrineedsapplication is the result of a study that aims to determine daily calorie needs for people withdiabetes mellitus. The level of accuracy of the NutriNeeds application will be compared with theBroca method in determining the daily calorie requirements for people with diabetes mellitus.The NutriNeeds application is designed with the mamdani fuzzy inference system and androidstudio, which uses 7 inputs in the fuzzy inference system, namely gender, male BBI, femaleBBI, age, BMI, physical activity, stress factors, and produces an output, namely calories daily.The NutriNeeds application requires data input, namely gender, weight, height, age, andphysical activity, which will display daily calorie results and meal schedules. The data in thisstudy were 5 pieces of data on patients with diabetes mellitus. Based on the comparison of dailycalories generated by the NutriNeeds application by calculating daily calories using the Brocamethod, the results of the calculation of the percentage of accuracy obtained a MAPE value ofthe NutriNeeds application of 1.1% which is classified as very accurate.

The use of hydroponics is an effective way to carry out farming activities without theneed for large tracts of land. Hydroponics requires extra supervision to be able to produceplants with good quality. There are three main parameters in hydroponics, namely the amountof dissolved nutrient content, the pH level in water, and the water suhue level. To provideconvenience in conducting surveillance, this research designed an IoT-based NFT hydroponicmonitoring system. The use of TDS sensors, pH sensors, and temperatur sensors DS18B20 inthis study are used to measure any changes that occur in the three parameters. Sensor datawill be processed by Arduino Mega 2560 and sent to Firebase databases via NodeMCUESP8266 which is connected to the internet network, so users can supervise anytime andanywhere through the android mobile application.
