The increase in the number of elderly motivates academic researchers to develop technologies that can ensure selfsufficiency in their lives. In this research, prototype of an inexpensive video monitoring system for the elderly using a single RGB camera proposed. In the process is divided into two, namely vision and event recognition module. For event recognition, we use a hierarchical description-based approach with three attributes, namely posture (e.g., stand, sit and lie), location (e.g., walking zone, relaxing zone and toilet zone) and duration (e.g., short and long). Output this system is description activity recognized in the text. The experiment result shows our system can provide the effectiveness of the context description.

Deaths due to temperature instability often occur in premature babies. Negligent handling of new-borns can pose a risk of temperature instability as well. Therefore, interventions to keep the baby’s body temperature warm can reduce the risk of infant death. An incubator is a box equipped with a temperature controller to maintain a baby’s average body temperature. The faster nursery controlled the heat, the quicker the handling of the baby from the risk of temperature instability. This research aims to design a baby incubator that has an automatic control system for working temperatures quickly. The method to be used is Fuzzy-PID control, which functions to maintain temperature stability and accelerate the system’s response to the incubator. The temperature in the nursery is measured using a DHT22 sensor. The temperature measured from the sensor use error and delta error as input parameters in the design of the fuzzy membership set. The heater used in this study is an incandescent lamp to produce heat that is safe for babies. An experiment was carried out by comparing the PID control to determine the speed of the system response. Besides, measurements to assess the stability of the controller are also carried out by analyzing the effect of the load on temperature variations. The test results show a faster system response compared to the PID control and stability at a temperature set point of 32 ° C, 33 ° C, 34 ° C and 35 ° C. The time needed to achieve balance at the highest temperature of set points is 205 seconds with a max overshoot of 0.5%. With the max overshoot, the incubator can still work at a temperature that is safe for babies.

Cane is one of the sugar-producing plants. The quality of produced sugar is greatly influenced by main raw material, cane juice, so sugar content measurement in sugar cane is needed. In this study, measuring sugar content in cane juice is integrated with a PC system. In addition to cane juice, sugar solutions are used as an object in this study. Measuring devices are made using light propagation principle when passing through the object. The light source used is RGB bright LED, fiber optic as a propagation medium of ray, photodiode BPW 34 as a photodetector, Arduino UNO module as a microcontroller module, and digital refractometer to obtain comparable data. The results showed that the measuring instrument could be integrated with a PC system. Research on sugar solution shows that yellow light is able to provide the greatest change in the output of sensor system for each variation of solution concentration, and a calibration curve is obtained for further study on cane juice. Research on cane juice shows that there are still differences in the results of sugar content measurement from photodetectors to digital refractometers.

The difficulty with parallel parking, especially when going backwards is when adjusting the steering wheel so that the car can park in the right direction. Based on these problems, this study aims to design an automatic parking system. To improve parking success, a trajectory tracking system with fuzzy logic control will be implemented on a 1/7.5 scale test car. The coordinates obtained from the bicycle kinematic model are compared with the design trajectory. The difference between the facing direction read by the gyroscope sensor and the trajectory design is processed using a fuzzy logic controller to direct the servo motor as the steering wheel. The test results obtained that the error value for the position and direction facing in the automatic parking test using fuzzy logic control is 1.25cm and 1.59°.

Alhamdulillah, akhirnya Bunga Rampai dengan tema “Rekayasa Keteknikan Dan Teknologi Informasi Terapan” ini dapat diselesaikan oleh Tim Penulis dan diterbitkan oleh Polije Press. Buku ini merupakan karya cetak dari Polije Press yang merupakan satu unit yang baru dibentuk di Politeknik negeri Jember untuk mewadahi hasil karya tulis dari bapak ibu dosen serta mahasiswa di Politeknik Negeri Jember. Ada beberapa alasan yang mendorong didirikannya Polije Press. Pertama, perlu adanya wadah yang bisa menampung aspirasi dari kaum cendekiawan di kampus Politeknik Negeri Jember dalam mengembangkan keilmuan nya serta menularkan kepada generasi penerus melalui tulisan-tulisan atau karya ilmiah. Alasan kedua adalah kehadiran Bunga Rampai ini diharapkan akan memberikan sumbangan signifikan dalam upaya peningkatan kualitas Penelitian dan Pengabdian kepada Masyarakat di Politeknik Negeri Jember. Apalagi, peningkatan kualitas Penelitian dan Pengabdian kepada Masyarakat adalah salah satu bagian komitmen penting Politeknik Negeri Jember dalam rangka mewujudkan pendidikan tinggi yang berkualitas bagi masyarakat Indonesia. Dengan adanya Bunga Rampai ini, diharapkan civitas akademika Polije akan lebih mudah dalam mengikuti perkembangan di dunia penelitian. Tentunya, buku ini telah dikaji secara mendalam oleh Tim Editor Naskah Politeknik Negeri Jember dan disusun sesuai dengan Rencana Induk Riset yang ditetapkan oleh Pusat Penelitian dan Pengabdian kepada Masyarakat (P3M) Politeknik Negeri Jember. Atas kontribusi tersebut, kami ucapkan terima kasih. Mudah-mudahan kita dapat memberikan yang terbaik bagi kemajuan dunia pendidikan dalam rangka mempersiapkan generasi seratus tahun Indonesia Merdeka (2045).

The increase in the number of vehicles especially cars causes the air environment to look polluted. This is caused by vehicle exhaust gases that can affect the level of human health. Harmful gases such as carbon dioxide (CO) and hydrocarbon (HC) can also enter the car cabin, making people inside feel suffocated and even death. To find out the presence of these gases, a monitoring system prototype is made which is placed in the car cabin. This system consists of input in the form of an MQ-9 sensor and a TGS2610 sensor. The readings of these sensors are processed by Arduino Uno. The system output is made in the form of a buzzer and LCD. Tests carried out on the car cabin area are divided into three, namely front, middle, and rear. The results of the 6 tests show that the smallest percentage of CO errors is 8% in the middle area and HC of 8.7% in the rear area of the car cabin.
