Abstract

Interconnected system between computationand physical process (Cyber-Physical Systems) has been widelyused in industrial processes. In CPS-based industrial process,sensors, controllers, and actuators are connected into acommunication network. The communication network mayintroduce delay time uncertainties due to shared resources andload traffic in the network. Furthermore, the nonlinear timevaryingcharacteristic of batch distillation column may causesanother uncertainties to take into account in control systemdesign. Parameter model and delay process uncertainty isintroduced due to linearized system approximation thatunmodeled high-frequency dynamics. The dynamicuncertainty on both I/O channel are also introduced to thesystem uncertainty. In this paper, robust PI and PID controllerusing AMIGO method with appropriate weighting function isdesigned to guarantee robust stability spesification of batchdistillation column. The impact of system uncertainties toclosed-loop system performances such as peak overshoot andintegral error is investigated. MATLAB/Simulink simulationis used to validate the methods before its implementation inCPS-based batch distillation column. Based on simulation, theproposed robust PI/PID controller can guarantee robuststability of system compared to conventional PID controller.Furthermore, the robust PI/PID controller can improve closedloopsystem performances compared to conventional PID.

Abstract

Nowadays, various problems have arisen in agricultural sector. One of which is the decline in productivity of farmers' crops up to 40% which is caused by non-optimal environmental conditions during the plant growth process. This is certainly a challenge for Indonesian farmers to be able to continue in supplying the country's needs for high quality agricultural products. The challenges faced by Indonesian farmers do not only come from the environmental conditions of plant growth, but the development of Industry 4.0 technology also plays an important role in the development of agricultural sector in Indonesia. In order to adapt to these technological changes, a solution is needed in the form of an integrated agricultural equipment with Industry 4.0 technologies such as the Internet of Things (IoT). One of which is creating an IoT-based control and monitoring system that will be applied to the screen house. In this research, an IoT-based temperature and humidity conditioning system was designed in the screen house. The system design is modeled and tested through simulation on Vensim software. Based on the simulation results of system design, the screen house internal temperature can be controlled or maintained in the optimal temperature range for tomato plant growth, which is 18–24oC with an offside value of ±0.5oC. The heating capacity or heating rate required in this system is 10oC/hour. The cooling capacity or cooling rate generated to compensate the influence of external temperature and heating effect on the screen house internal temperature is 1–1.8oC/hour. The heating and cooling rate values generated in this research are still need to be converted into fan and pump PWM values to be implemented in a fan- pad evaporative cooling system.

Abstract

Tulisan ini menganalisis tentang penggunaan kamera thermal imaging untuk pengecekan kebocoran refrigerant pada system refrigerasi. Dalam suatu prosedur perawatan sistem RHVAC, salah satu prosesnya merupakan pengecekan kebocoran pada pipa sistem RHVAC tersebut. Ada berbagai macam metode dalam melakukan pemeriksaan kebocoran pada sistem RHVAC. Pada tugas akhir ini akan dilakukan prosedur pemeriksaan kebocoran menggunakan metode yang jarang dipakai, yaitu menggunakan kamera thermal imaging. Alat ini dapat menangkap gambar suatu objek menggunakan radiasi inframerah sehingga distribusi temperatur objek tersebut dapat terlihat pada foto yang dihasilkan kamera thermal imaging ini. Pada suatu kebocoran fluida seperti refrigeran akan terjadi proses throttling yang menyebabkan adanya perbedaan temperatur fluida di dalam pipa dengan temperatur fluida yang keluar melewati lubang kebocoran. Dengan kamera thermal imaging hasil kebocoran dapat di deteksi, namun ada beberapa batasan dari kamera tersebut yang perlu diperhatikan dalam prosedur pengecekan kebocoran agar hasil yang didapatkan optimal.

Abstract

Thermoelectric has been used in various applications related to cooling systems (TEC). Most researchers focused on expanding the application of TEC and improving heat transfer. The improvement of the heat transfer relied on the configuration, heat exchanger, and fluid medium. However, no previous work has reported the influence of air and water as the fluid’s medium on the TEC performance. Therefore, in this study, the performance of TEC with water and air as working fluids is evaluated experimentally. Besides, several input parameters are controlled to evaluate the TEC performance under different conditions. The results reveal that the variation of working fluid and input parameters influenced the overall TEC output. The increment of TEC cooling capacity is proportional to the input power, mass flow rate, and inlet temperature of the working fluid. While the input power and inlet temperature also vary the heat exchanger thermal resistance. The overall thermal resistance of the water block is averagely ten times lower than that of the heat sink, therefore, the water block is significantly better compared to the heat sink. While the highest COP obtained from the water and air system is 1.72 and 1.41, respectively.

Abstract

The unpredictable weather changes in Indonesia cause various problems for the agricultural sector. One of which is the decline in productivity of farmers' crops up to 40% which is caused by non-optimal environmental conditions during the plant growth process. To be able to adapt to these conditions, it is necessary to have an optimal system of environmental conditioning for plant growth. In this research, a screenhouse temperature and humidity conditioning system was designed for the growth of tomato plants as a horticultural commodity with high potential and high economic value in Indonesia. The system design is modeled and tested through simulation on Vensim software by varying the furnace capacity by 4oC/hour, 6oC/hour, and 10oC/hour in order to see its effect on the internal screenhouse temperature and heating duration. Based on the simulation results of system design, the heating rate and duration for each furnace capacity variation are 4.74oC/hour (135 minutes per cycle), 6.9oC/hour (75 minutes per cycle), and 11.76oC/hour (45 minutes per cycle). The furnace capacity value of 10oC/hour is considered to be optimal and more energy efficient because it only requires a heating process for 180 minutes per day to maintain the screenhouse internal temperature in optimal temperature range for tomato plant growth, which is 18 - 24 oC with an offside value of ±0.5 oC. The stable cooling rate value for this system is in the range of 1 – 1.8oC/hour.

Abstract

The M-bus protocol is one of the communication protocols in the rapidly developing field of measurement. The protocol uses a pair of cables and can communicate with several measurement devices in two directions such as a flowmeter. In the chiller system, water circulation varies depending on the cooling load and set point of operation, consumption (electric power) and chiller efficiency, one of which can be calculated based on logging the flow of water that circulates over time, therefore the water discharge data logger becomes very important. This study aims to examine the water discharge data logger with the M-Bus protocol for chiller applications. The testing device includes a series of bench water meters as flowmeters (which water can be simulated circulated) equipped with an M-Bus pick-up sensor, M-Bus concentrator and logger, and software connected to a computer. Tests carried out with variations in water discharge based on the valve opening as a simulation of cooling load variations and see the results of recording from time to time on a computer. The display can be in the form of tables and graphs.

Abstract

Dalam bidang refrigerasi dan tata udara, kebocoran refrigeran merupakan hal yang seharusnya dihindari. Namun, ketika sudah terlanjur bocor maka diperlukan pendeteksian dini agar kebocoran dapat dihentikan. Untuk mencegah kebocoran yang lebih banyak serta mendeteksi adanya kebocoran tersebut maka dilakukan rancang bangun sistem simulasi pendeteksi kebocoran refrigeran. Untuk itu digunakan board ESP8266 sebagai mikrokontroler serta software Arduino IDE. Menggunakan sensor MQ-6 yang mampu mendeteksi gas yang mengandung LPG, butana, propana, dan LNG. Hasilnya adalah ketika refrigeran bocor telah mencapai nilai ambang batas yang dirancang, sistem ini akan memberikan peringatan berupa bunyi buzzer di sekitar lokasi peralatan dan secara bersamaan mengirimkan peringatan ini ke smartphone melalui WhatsApp dengan bantuan bot dari callmebot yang terus mengirimkan peringatan setiap 5 detik sekali selama refrigeran yang terdeteksi berada di atas nilai ambang batas.
