The community health centres, or commonly known as Puskesmas in Bahasa, are the backbone for Indonesia citizens in dealing with and fighting against the Covid-19 outbreak. They are the first responders and primary services that is closest to the community. Their healthcare professionals have a very important role as the front lines that identify the symptoms at the village level. It is mandatory that they use adequate personal protective equipment (PPE) when examining people's health. With the PPE, healthcare professionals remain protected from the risk of Covid-19 exposure. The lack of PPE availability sometimes makes many officers have to use any available materials as their protection. Addressing the lack of PPE availability in a Puskesmas of a suburban area like Bungus, the Department of Computer Systems, Universitas Andalas, decides to put some innovations into practice. In this community service activity, certain PPE and sterilization tool-aids are designed and developed to protect healthcare professionals from the risk of Covid-19 exposure. Some of the types of equipment provided for the centre are portable sterilization poles, hand sanitizer tool-aids that can be used without having to be touched by hands, face shield in the form of a face-covered hat using mica material that can be reused by washing or wiping it using a disinfectant, and hijack-masks made from spun-bond fabric that is comfortable and waterproof.

[Id]Penderita autisme atau biasa disingkat autis pada umumnya membutuhkan pegawasan setiap harinya agar kebutuhan penderita dapat dipenuhi. Ada beberapa resiko yang mungkin timbul jika pengawas atau penghuni rumah terlambat mengetahui keberadaan penderita. Penelitian ini dilakukan untuk mengimplementasikan teknologi RFID sebagai tag penanda yang dipasang pada lengan penderita autis. Setiap tag yang terbaca oleh Reader pada tiap lokasi akan dijadikan input pada sistem untuk menentukan karateristik situasi pada lokasi tertentu (Contex-Aware). Penelitian ini menggunakan kategori context-triggered action, karena sistem diharapkan dapat bereaksi secara otomatis berdasarkan context yang ada dan terdeteksi. Mekanisme inferensi menggunakan aturan IF-THEN. Implementasi disain sistem yang telah dirancang dengan meletakan reader RFID di masing-masing pintu pembatas ruangan rumah. Dalam penelitian ini akan digunakan 4 ruangan sebagai simulasi, yaitu: kamar tidur, dapur, ruang tengah, dan kamar mandi dengan asumsikan penderita autis tidak melakukan aktivitas di luar ruangan rumah seperti teras atau pekarangan. Karena keterbatasan pada implementasi sistem, komputer digunakan sebagai penampil dan pengolah data lokasi tag melewati sebuah RFID reader. Hasil pengujian menunjukan bahwa lokasi penderita dapat ditentukan berdasarkan hasil pembacaan reader RFID dengan tingkat keberhasilan dari 10 kali pengujian sebesar 70%.Kata kunci: Context-aware, RFID, Arduino, Autisme[en]Autism or commonly abbreviated as autis generally require supervise every day so that the needs of patients are met. There are some risks that may arise if the supervisor or the occupants of the house late know the whereabouts of the patient. This research was done to implement RFID technology as a tag put on the arm of an autis. Each tag is read by a reader at each location that later will be used as input to the system to determine the characteristics of the situation at a particular location (Contex-Aware). This research uses a context-triggered action category, because the system is expected to react automatically based on the existing context that are detected. IF-THEN rules are used for inference mechanism. Design implementation system has been applied by locating RFID reader at each door of the house room. In this reseach, four rooms will be used as a simulation, namely: a bedroom, kitchen, living room, and a bathroom with autistic patients do not assume doing an outdoor activity such as a terrace house or yard. Due to limitations in the implementation of the system, the computer is used as a viewer and data processor locations RFID tag passes through a reader. The test results showed that the location of the patient can be determined based on the reading of RFID reader with a success rate of 10 times testing by 70%.

Rice cooker yang dijual di Indonesia dengan harga relatif murah umumnya belum dilengkapi pengaturan suhu pada saat memanaskan nasi. Pada saat memanaskan nasi, suhu yang dihasilkan relatif tidak sama untuk kuantitas nasi yang berbeda. Tidak adanya pengaturan suhu pada keadaan ini akan mempengaruhi kualitas nasi. Salah satu masalah yang timbul akibat tidak adanya pengaturan suhu pada rice cooker adalah tidak adanya perubahan suhu rice cooker saat kuantitas nasi berkurang. Hal ini menyebabkan kualitas nasi menjadi berkurang dan cepat kering, akibat suhu yang tetap tinggi. Pengujian telah dilakukan terhadap beberapa varietas beras unggul Sumatera Barat untuk melihat apakah tekstur dan sifat beras mempengaruhi kualitas nasi yang dihasilkan. Ditetapkan nilai 74°C sebagai set poin pada fuzzy logic untuk pengontrolan kestabilan suhu penghangat nasi. Hasil pengujian menunjukan rice cooker TP, tanpa pengontrolan fuzzy logic menghasilkan suhu yang cenderung naik seiring dengan berkurangnya massa nasi. Semakin kecil massa nasi, semakin besar nilai suhu yang dihasilkan selama memanaskan nasi. Hal ini menyebabkan nasi yang ada dalam rice cooker menjadi lebih cepat kering, karena kadar air nasi lebih cepat berkurang akibat suhu yang lebih tinggi. Rice cooker PF, yang menggunakan kontrol fuzzy logic menghasilkan suhu yang relatif stabil meskipun massa nasi telah berkurang, karena sistem akan mempertahankan suhu agar tetap berada sesuai set poin yaitu 74°C.

Selain beras putih, terdapat beberapa jenis beras yang beredar di pasaran seperti beras merah, beras hitam serta beras ketan dengan bentuk, struktur dan kandungan yang berbeda. Perbedaan ini membutuhkan cara pengolahan yang berbeda pula. Beras ketan memiliki tekstur yang jauh lebih keras tetapi juga mudah lembek. Di Indonesia, rice cooker yang dijual dipasaran masih digunakan untuk memasak beras biasa. Proses memasak ketan menggunakan rice cooker tentu bisa dilakukan. Tetapi, untuk mengolah beras ketan dengan rice cooker dibutuhkan metode yang tepat. Penelitian ini menerapkan konsep kontrol rice cooker menggunakan metode fuzzy logic untuk jenis beras ketan. Pengontrolan dilakukan pada tahapan merendam (soaking) dengan nilai set poin suhu 30 oC. Fuzzy Logic akan menghasilkan nilai PWM sebagai output, sehingga dapat memberikan nilai tegangan yang sesuai agar suhu rice cooker akan tetap stabil di titik 30 oC selama 30 menit. Hasil pengujian sistem secara keseluruhan untuk 3 jenis massa beras menunjukan bahwa perbedaan massa tidak mempengaruhi lamanya fase merendam, karena telah diimbangi dengan penggunaan air yang sesuai. Ketan yang dimasak menggunakan rice cooker yang dikontrol memiliki tekstur yang lunak dan lengket serta matang secara merata jika dibandingkan dengan ketan yang dimasak tanpa pengontrolan.

Robotics is a field of science that is developing rapidly, One of Robotic field is a wheeled robot whose sample application allows robots to explore automatically. But today, more research on the application of artificial intelligence in robot control is aimed at obtaining sophisticated kinematic control. In this final project, a wheeled robot will be designed with the ability to detect obstacles. As a control object is a robot tank that both wheels use a belt wheel and have a separate DC motor. A fuzzy logic controller functions to regulate the speed and direction of the robot's motion based on the input of the ultrasonic sensor. The design of robots based on the embedded microcontroller is designed using the C language. From the test results, that fuzzy logic can be embedded in the ATmega328 microcontroller control unit on Arduino Uno, so that a robotic motion can be avoided that can avoid obstacles properly. The closer the obstacle distance results in the sharpening direction of the robot and the more rigorous robot movement.

Electrocardiograph (ECG) is a recorder of human heart signals with signal output on a monitor or graph paper. The ECG records the measurement of the electrical activity of the heart from the surface of the body by a set of electrodes that are installed in such a way that reflects the tapping point activity. The pattern of ECG output signals in one heartbeat produces a pattern with a peak point P, Q, R, S and T or QRS complex. ECG signal waveform results were analyzed using Learning Vector Quantization (LVQ) Artificial Neural Networks, and grouped into two classes, namely normal and abnormal heart patterns. The normal heart condition that is trained is a medically normal heart categorized as healthy as 10 data, while an abnormal heart (Heart, Coronary Heart, and Aortic Regurgutation) is 20 data. The LVQ method recognizes the input pattern based on the proximity of the two vectors, namely the vector of the input unit or neuron with the weight vector produced by each class. Online LVQ identification (using ECG) recorded from 25 direct trials resulted in 80% accuracy.
