Indra Dwisaputra, Boy Rolastin, Irwan, Angga Satera, in this paper explain that one commodity that can be used as a superior post-mining area such as Bangka Belitung is shrimp ponds. Touch of technology is needed because of high rainfall in this area so that changes in temperature, humidity, salinity and pH are more dynamic. Then we need a control to determine the water quality in shrimp ponds to avoid crop failure. This research was conducted by means of simulations to make it easier to analyze the results before applying. Fuzzy logic control (FLC) method is used for the water quality decision making system. By utilizing 3 input variables such as temperature, salinity and pH of water and output is an index of water quality from a scale of 0-100. The Mamdani method is applied to FLC with 27 fuzzy rules. The simulation results show that a change in one of the input variables can cause water quality to drop to 70. When there are changes in the two input variables, it can reduce water quality by 25.1. FLC can work well in decision making for water quality in shrimp culture.

In this paper, a dynamic model of two-wheeled balancing robot has been created, and the two types of FLC has been designed. The Mamdani methods used on both FLC. The first FLC uses pendulum tilt angle theta (?) as the input and it requires the motor torque to keep the robot remains balanced as the output. The second FLC uses two inputs, the first input is theta (?) and the second input is the change in the value of theta (?) which is the output torque of the motor. The second plant model and FLC built by using Matlab Simulink. The first case is one input using 5 membership functions (mf). The second case is two inputs using the 5 and 7 mf. The characteristics and effects of the changes in the input and mf have been simulated in the Simulink and compared. By expanding the number of the inputs can reduce motor specification required in balancing robot. Meanwhile, by increasing the number mf, it can improve the performance of the controller much faster to reach the settling time.

The dancing robot has become an annual competition in Indonesia that needs to be developed to improve robot performance. The dancing robot is a humanoid robot that has 24 degrees of freedom. For 2018 the theme raised was "Remo Dancer Robot". Sound processing provides a very important role in dance robots. This robot moves dancing to adjust to the rhythm of the music. The robot will stop dancing when the music is mute. The resulting sound signal is still analogous. Voice signals must be changed to digital data to access the signal. Convert analog to digital signals using Analog Digital Converter (ADC). ADC data is taken by sampling time 254 data per second. The sampling data is stored and grouped per 1 second to classify the parts of Remo Dance music. The results of data classification are in the form of digital numbers which then become a reference to determine the movement of the robot. Robots can recognize conditions when music is in a mute or a play condition.

Bangka Island has high sunlight intensity, but it still has little use as an alternative energy source. Water heater available on the market have experienced a peak of innovation that continues to use electricity as energy, but as we know that heater that use electricity consume a lot of energy. In this research, a solar water heater machine with spiral collector will be made to heat water in a reservoir using sunlight energy and as a tool to see the difference between the continuous method which circulates water continuously from the reservoir to the heat collector with a delay method that circulates water with a certain delay time. Both methods and data retrieval mechanisms are controlled by an Arduino device. Based on the results of the trial, it was found that Solar water heater was able to heat water in reservoir up to 48.92 degrees Celsius and the use of the continuous method made the water temperature higher than the delay method with a maximum difference of 10.66 degrees centigrade.

In the Programmable Logic Controller (PLC) course at Polmanbabel, students use a practicum table containing practicum equipment such as computer units, compressors, PLC units, pneumatic valves, sensors, jumper cables, etc. Before and after practicum, students are required to do an inventory of equipment and materials contained on this practicum desk. The inventory process is still done manually, where students write the name of the equipment, check the presence of the equipment, and calculate the amount. The thing that was complained by lecturers was the confiscation of practicum time as a result of the manual inventory process. Based on this, a new inventory system was created that uses the application and is equipped with a barcode scanner that is able to minimize the time and possibility of misplacement of the device. Based on the results of experiments, it can be seen that this system is able to minimize inventory time by an average of 14.65 minutes compared to manual inventory systems.

Nitrate is one of the nutrients that can give an effect on the environment if it is applied in excess. It is also easily soluble in water and it has the potential to be a pollutant in groundwater by the over-process of fertilizer. Therefore, it needs a detected component to give the right measure for nitrate in the soil, called a nitrate ion sensor. It consists of three electrodes configuration, namely, working, counter, and reference electrodes with conductive polyaniline doped with Nitrate (NO₃‾) which is fabricated by thick film technology. In previous research, acidic media was used as a solvent for polyaniline, while this research used water (H2O) solvent. The result of characterization showed that particles were distributed evenly on the sample with the form of particles being small balls with a dimension of 0.18 µm and the percentage of atomic elements being: 91.96 % carbon, 3.14 % nitrogen, and 4.9 % oxygen. The performance of sensors was investigated using potentiostat with four concentrations of nitrate standard solution. The result showed good response with a voltage range in each concentration of nitrate standard solution being 0.5002 Volt (10 mg/l), 1.3552 Volt (20 mg/l), 1.1208 Volt (50 mg/l), and 0.8963 Volt (100 mg/l). It was found that nitrate sensors with nitrate-doped conductive polymer, polyaniline, as the sensitive membrane responded well to detecting nitrate elements in precision farming and the sensitivity showed that for every 1 mg/l concentration in nitrate standard solution, the voltage increases by 0.0007.

In the industrial technology of cassava processing in Bangka Belitung, for now the level of productivity and efficiency of its performance can be said to be still minimal. This is because there is no supporting technology to measure the value of sweet potato starch levels digitally and efficiently. In this final project, a tool is designed to measure the starch content of cassava digitally based on SMS using the method specify gravity. The way this tool works is by measuring the mass of cassava in the air and in water using a driving medium in the form of a DC motor gearbox to raise and lower the cassava. Meanwhile, the sensor loadcell and HX711 are used for converting analog to digital data. The percentage of error obtained between the comparison of the weight value read on the sensor and the digital hanging scale is 0.282% and the result of the measuring instrument is able to measure starch content with a capacity of with an error of 2.45%. The measurement data can be sent via the SMS feature using the SIM800L V2 module with an average delivery speed of 7.12 seconds.
