Abstract

Hydrazine is a dangerous chemical compound that is widely used in various industries. The presence of this compound in the waters resulting from the disposal of industrial waste must be monitored and controlled for its presence. For this reason, a sensor is needed that can be used to detect the presence of this compound in the waters. Commercial carbon electrodes are environmentally friendly materials and are relatively cheap to be used as potential sensor materials, but these materials have low electrochemical activity and are hydrophobic. To increase the electrochemical activity of the carbon electrode, modifications were carried out using CuS-Nafion and CuS@rGO-Nafion materials which were synthesized through solvothermal reactions and dropped-casting on the surface of the carbon electrodes. The modification was successfully carried out which was shown by the results of scanning electron microscopy which had a high response to the hydrazine compound shown from the results of cyclic voltammetry (CV) analysis. The best result is shown by carbon electrode modified using CuS@rGO-Nafion materials. The electrochemical impedance spectroscopy (EIS) results showed excellent results where the Rct value was 2178 Ω which could facilitate high electron transfer on the modified electrode surface.

Abstract

Modify the palm fruit thresher machine into a thresher model dry split betel nut peeler by testing the tool so that it can find out the constraints of the palm fruit thresher machine, and disassembling the components or parts to be modified, namely; cover, collection channel, blade and drive clutch. The cover is designed to function to be sturdy from the impact of areca nuts and is cylindrical. The reservoir channel is designed to allow the peeled betel nut to enter the drain pipe and the blower is in charge of blowing between the peeled betel nut and the seeds. The blade is designed to peel the dry split betel nut. The drive clutch is designed to function as a connector/breaker for the engine rotation to the shaft and plain concrete iron and bearings as a v-belt retainer. In the test with a capacity of 50 kg 1 day drying, peeled 40 kg and unpeeled 10 kg with an average time of 15 minutes is the best test. Therefore, we can conclude that the best peeling results from this dry split betel nut peeler machine are almost 80% peeled.

Abstract

A rapid development of the concrete construction sector has resulted in an increase in the need for concrete raw materials that are obtained directly from nature. The need for environmentally friendly materials is also increasing along with the development of construction engineering technology, so several studies have been conducted to search for an alternative to raw materials additives or concrete mixtures. Anadara granosa clam shell can be utilized as one of the alternative materials to substitute material for coarse aggregates. In this research, Anadara granosa clam shells of 10% and 13% were added to normal concrete mixtures, aged for 28 days, and then analyzed for characteristics and compressive strength. From the analysis of the results, it was found that an increase in the concrete compressive strength up to 103.67% or 233.47 Kg/cm2 with the addition of clam shells 10% to normal concrete mixtures, while the addition of more than 10% can reduce the concrete compressive strength. Scanning Electron Microscopy results showed a relatively rough surface and many pores on the surface of the concrete due to the addition of a clam shell. Finally, it can be concluded that Anadara granosa clam shells can be used as concrete additives with a maximum addition of 10% of the total weight of normal concrete.
