In this research, the water turbidity measurement tool based on Arduino Uno has been designed and built using phototransistors and infrared LEDs. This measuring instrument consists of a series of infrared sensors, Arduino as a process, LCD I2C as a value viewer, Micro SD as a data storage, and RTC as a timer. This study used two water samples with various concentrations. The sample used, namely distilled water plus impurities in the form of soil and ash. The distilled water used is still 100 ml with variations in the concentration of impurities ranging from 0,1-0,9 gr. Sensor test results show that the greater the turbidity level, the greater the voltage obtained. Sensor scanning ranges from 2,02 V-4,00 V for groundwater and 2,02 V-4,31 V for ash water. The reading uses a standard measuring instrument for groundwater ranging from 0 NTU to 331,4 NTU, while for ash water ranging from 0 NTU to 284,4 NTU. Data from the sensor test results in an equation used to convert the artificial measuring instrument's voltage value into a turbidity value. Then, data is taken using the same sample, so groundwater's turbidity value was obtained from 0 NTU to 318,94 NTU while for ash water from 0 NTU to 285,13 NTU. Based on the results, average accuracy for water was obtained. Soil amounted to 94,66%, while for ash water was 96,63%.

Effect Method

One of the essential instruments in the cyber era is data. Therefore, maintaining data security is an important thing to do. One way that can be done to maintain data security is through cryptography. In cryptography, two basic techniques are commonly used, namely substitution techniques and transposition techniques. One of the weaknesses of the basic cryptographic techniques is the lower level of data security. This study proposed a super encryption model in securing data by combining cryptographic algorithms with substitution techniques, i.e., autokey cipher and transposition, i.e., columnar transposition cipher. This study used the Avalanche Effect method as a measurement tool for the proposed super encryption model. The test results have shown that the proposed super encryption model can provide a better level of security. The avalanche effect test on the five data test shows that the average AE value of the proposed super encryption model is 30.76%. This value is higher than the single autokey cipher algorithm of 1.66% and column transposition with a value of 18.03%. Other results from the five data test have shown that the proposed model has a high level of accuracy of 100% in terms of the decryption process results, which is the same as the initial data before going through the encryption process.

ABSTRACTThe purpose of this research is to design and make a real tool in the form of a drying cabinet for cocoa beans. Because this solution can relieve the farmers who previously drained the cocoa beans in the sun. This drying cabinet uses the Arduiono Uno 328P control and heater element as a heater. This cabinet is also equipped with a DC motor mechanical device to drive the cocoa drying container. This tool is also equipped with a DHT12 sensor which is a resistive sensor whose value changes depending on the water content of the cocoa beans. The sensor plays a role in detecting the temperature and humidity of the seeds in the cacao drying room. Then the output inverting amplifier voltage is read by the ADC Arduino UNO 328p microcontroller, which is then processed and displayed on the LCD. The test results showed that the measuring instrument made was able to measure the amount of water contained in cocoa beans in the range of water content measurement from 60% to 7.5%. Keyword: Cocoa Beans, Temperature, Arduino, DC Motor, DHT Sensor

Global Fairness

With the development of the Intelligent Transportation System, various distributed sensors (including GPS, radar, infrared sensors) process massive data and make decisions for emergencies. Federated learning is a new distributed machine learning paradigm, in which system heterogeneity is the difficulty of fairness design. This paper designs a system heterogeneous fair federated learning algorithm (SHFF). SHFF introduces the equipment influence factor I into the optimization target and dynamically adjusts the equipment proportion with other performance. By changing the global fairness parameter θ, the algorithm can control fairness according to the actual needs. Experimental results show that, compared with the popular q-FedAvg algorithm, the SHFF algorithm proposed in this paper improves the average accuracy of the Worst 10% by 26% and reduces the variance by 61%.

The aim of the study was to evaluate the effect of different concentrations of cetrimide with or without EDTA solution on the microhardness and surface changes in root dentin. Single rooted human mandibular premolar teeth were decoronated and sectioned longitudinally. The root segments were horizontally embedded in autopolymerizing resin. These specimens were randomly divided into 6 experimental groups according to the irrigating solution used. The irrigating solutions used were 5% EDTA, 5%EDTA + 0.25% Cetrimide, 5%EDTA + 0.50% Cetrimide, 0.25% Cetrimide, 0.50% Cetrimide and distilled water. Each group was further divided into two subgroups. First subgroup specimens were employed for microhardness testing using vicker’s indenter. Second subgroup specimens were used to evaluate the surface changes of root dentin under stereomicroscope. Comparison of the mean microhardness of test groups was done using ANOVA followed by post hoc Tukey’s test. Pre- and post- treatment hardness values were compared using student paired t test. The data obtained from surface erosion scoring was subjected to statistical analysis using Chi square test. Results of this study showed significant reduction in the microhardness of dentin for all the groups except for the distilled water (p<0.001). The greatest reduction in dentin microhardness was observed with Group-3 (5% EDTA + 0.50% CTR). Specimens in 5% EDTA group showed greater erosion than other groups. Within the limitations of this study it was concluded that all the tested irrigating solutions reduced the microhardness of root dentin except distilled water. Maximum reduction in microhardness was observed with addition of 0.50% cetrimide to EDTA. EDTA increased the surface roughness of root dentin irrespective of cetrimide association. Use of cetrimide at concentrations higher than 0.25% would be detrimental to the microhardness of dentin.
