Abstract

Abstrak Banyak cara untuk mengetahui keberadaan para dosen dan mahasiswa pada saat aktifitas perkuliahan, mulai dari cara lama menggunakan kertas lembar presensi, menggunakan barcode hingga cara yang sudah terkomputerisasi. Dan permasalahan yang sering timbul dalam Politeknik Negeri Malang adalah perhitungan absensi yang memakan waktu lama dan membutuhkan usaha ekstra untuk merekap data dari lembar absensi mahasiswa pada setiap kelas. Pada penelitian ini, sistem absensi akan menggunakan teknologi RFID (Radio Frequency Identification). Dimana setiap dosen dan mahasiswa akan memliki tag RFID dengan nomor identitas masing-masing yang akan digunakan untuk melakukan absensi. Tag RFID tersebut akan dipindai dan data yang didapat akan disimpan pada database berupa nama, tanggal, hari, jam hadir dan jam keluar. Dari data tersebut akan diolah shingga dapat diketahui jumlah kehadiran dosen, absensi, dan jumlah kompensasi dari mahasiswa. Pada penelitian ini kinerja, kecepatan, jarak jangkau dan ketahanan dari noise diteliti menggunakan aplikasi Wireshark. Dan didapatkan bahwa sistem dapat berjalan dengan waktu yang sangat singkat, waktu rata-rata yang digunakan untuk mengirimkan data adalah 447ms dan masih dapat bekerja meskipun terhalang oleh kertas dengan ketebalan dibawah 2.8cm. Sehingga dengan menggunakan aplikasi ini, proses absensi dan proses perhitungan kompensasi yang semula cukup lama dan membutuhkan usaha ekstra dapat dilakukan dengan cepat dan efisien. Abstract There are many ways to find out the whereabouts of lecturers and students during lecture activities, like using old method by writing in presence sheet paper, using barcodes or using computerized methods.

Abstract

Antlion habitat that breeders create currently does not use a system that can protect the habitat from changes in temperature and humidity. In addition, when they are about to be sold, breeders filter and sort the antlion one by one. Therefore, a system is made that can monitor and control changes in temperature and humidity as well as harvesting automatically through the application. This system is designed using a wireless sensor network with temperature and humidity sensors DHT22, IR MLX90614 with soft actuators and mist makers as well as loadcell sensors to trigger off the sieving motor connected to the Firebase database and interface Flutter application. Based on the results of testing the accuracy of temperature, humidity, infrared, and loadcell sensor readings, respectively, they are 98.07, 97.58%, 98.38%, and 98.78% with an average delay of 216,97ms can maintain temperature changes in the range 24-30? and humidity in the range 70-80% stably. And the average value of harvest time is 30.37 seconds with an average decrease in sand load of 56.7 grams when the harvesting mechanism is running.

Abstract

A key is a tool made of metal to open or fasten a door or object that has a lock by inserting it into the hole in the main key. The lock itself is usually used on doors, suitcases, or other objects that require security. The lock on the suitcase itself still has a slight variation and there are still weaknesses, for example the code lock if you forget it cannot be opened, then the padlock and slot lock if the key is lost cannot be opened and can still be broken into by lockpick. The type of research carried out is included in the type of research and development (Research and Development). So, from these problems, a system will be designed and built that can monitor and maximize security automatically so that user's goods are protected from crime or theft by utilizing Near Field Communication (NFC), Global Positioning System (GPS), Magnetic Sensors and Microcontrollers. This system is made portable, so that it can be used in various goods with certain conditions, for example suitcases. The results of this research are portable lock tools, and applications that can integrate lock tools in real time. From the test results obtained accuracy on the gps key, and the security system can run according to the program.

Abstract

The food filling system in raising chickens is still relying on human power. Breeders must regularly check on everything in the cage.  In addition, if the farmer forgets to check it will be fatal and will affect chicken production. The research method will be carried out by monitoring feeding, drinking, vitamins and cleaning cages when ammonia gas is detected which increases above 50. Where in previous studies it was still done manually. Automatic control will be carried out using a microcontroller as the command brain and processing sensor data on the system. Where the trigger for cleaning is based on the ammonia level, while for feed it is based on the volume of the place to feed and drink. The weight sensor has an accuracy rate of 99.9% while the range is 99.13%. For the measurement of chicken manure ammonia gas can be done with a reading accuracy level of 99.69%. After using this system, the value of weight and gas content of Ammonia decreases from the first day to the third day. From the 3-day test, the highest value of ammonia gas content was obtained at a value of 197.56 ppm with a weight of 9.8 grams. The lowest was obtained on the third day with ammonia gas content of 18.37 ppm with a weight of 2.1 grams. For network quality, the system has an average delay of 0.07580 seconds and the packet loss obtained when testing is 6.11% (Very Good).

Abstract

Snails or with the Latin name Achatina fulica are soft-bodied animals with shells on their bodies. Snails can be found in Indonesia during the rainy season, but are quite difficult to find during the dry season. This is due to high temperature conditions and low air and soil humidity during the dry season, making it difficult for snails to survive. Therefore, a system is made that can see the physical condition of the environment and control it using fuzzy logic because snails can survive in a certain temperature and humidity range. To see the physical condition of the environment, this system uses a DHT22 sensor, a soil moisture sensor and a BH1750 sensor. The results of the sensor readings of air temperature, air humidity and soil moisture will be sent to a website which will later be processed using fuzzy logic and will receive a response in the form of an actuator activation time range in the form

Abstract

Stroke Transient Ischemic Attack (TIA) adalah kondisi stroke ringan yang dapat disebabkan oleh berkurangnya suplai darah menuju otak diakibatkan pembuluh darah tersumbat. Kurangnya aliran darah ke otak dapat menyebabkan kelumpuhan, biasanya hanya pada satu sisi tubuh. Fisioterapi pada pasien pasca stroke ringan dilakukan dengan metode terapi gerakan antara lain yaitu elbow dan knee flexion. Fisioterapi adalah metode pengobatan yang umum digunakan oleh masyarakat, pengobatan ini mahal dan memerlukan mobilitas. Berdasarkan data riset kesehatan dasar, ditemukan bahwa status ekonomi merupakan salah satu penentu utama efektivitas fisioterapi. Oleh karena itu, dibuatlah alat smart hand glove terapi pasien pasca stroke yang digunakan pada bagian tangan dan dilengkapi sebuah aplikasi yang disebut sebagai "Therapy Stroke Technology (TASTECH) untuk monitoring. Alat ini bekerja dengan integrasi antara sensor MPU6050 dan MAX30102 yang terhubung dengan ESP32 serta dapat dimonitoring oleh dokter atau terapis. Dari hasil pengujian akurasi sensor MPU6050 mampu mendeteksi sudut dari 100-900 sebesar 98,64%. Kemudian untuk sensor MAX30102 setelah diuji akurasi dengan perbandingan pulse oximeter tipe Lk87 didapatkan nilai akurasi SPO2 99,37% dan rata-rata BPM 99,22%. Aplikasi TASTECH ini dilengkapi dengan berbagai menu menarik seperti pusat informasi dan konsultasi yang dibuat dengan user friendly, TASTECH juga dapat digunakan dimana dan kapan saja dikarenakan bentuk alat ini yang portable dan tentunya ergonomis. ABSTRACTTransient Ischemic Attack (TIA) stroke is a mild stroke condition that can be caused by reduced blood supply to the brain due to blocked blood vessels. Lack of blood flow to the brain can cause paralysis, usually on only one side of the body. Physiotherapy in post-stroke patients is carried out using movement therapy methods, including elbow and knee flexion. Physiotherapy is a treatment method that is commonly used by the community, this treatment is expensive and requires mobility. Based on Basic Health Research data, it was found that economic status is one of the main determinants of the effectiveness of physiotherapy. Therefore, a Smart Hand Glove tool was created for post-stroke patient therapy which was used on the hands and equipped with an application called "Therapy Stroke Technology (TASTECH) for monitoring. TASTECH works by integrating the MPU6050 and MAX30102 sensors that are connected to the ESP32 and can be monitored by a doctor or therapist. From the results of testing the accuracy of the MPU6050 sensor is able to detect angles from 100-900 by 98.64%. Then for the MAX30102 sensor after being tested for accuracy with a comparison of the Lk87 type pulse oximeter, the SPO2 accuracy value is 99.37% and the BPM average is 99.22%. The TASTECH application is equipped with various interesting menus such as an information center and consultation which is made user friendly, TASTECH can also be used anywhere and anytime due to the shape of this tool which is portable and of course ergonomic.
