Abstract

The aim of this research is to know the difference of time and of the result of plastic waste enumeration on blade before and after modification to material weight of 250gr, 500gr, and 750gr. This study compared the length of time and of the enumeration results on the blades before they were modified and after modified. Variations in waste weight were 250gr, 500gr, and 750gr. The results showed that the percentage comparison of the length of the process of enumerating plastic waste before modification with the weight of 250gr resulted in enumeration time for 35 seconds, so that the effective capacity of the tool was 25.71 kg / hour. For weight of garbage equal to 500gr produce enumeration time for 126 second, with tool capacity 14,28 kg/hour. While the weight of garbage 750gr produce enumeration time for 192 seconds, with the effective capacity of the tool of 14.06 kg/hour. For the conditions after modification of the blades, the weight of the waste of 250gr resulted in an enumeration time of 80 seconds, in which the effective capacity of the apparatus was 11.25 kg/hr. For the weight of garbage of 500gr was resulted enumeration time for 255 seconds, where the effective capacity of the tool obtained was 7.05 kg/hour. While the weight of 750gr garbage generates the enumeration time for 401 seconds, where the effective capacity of the tool obtained of 6.73 kg/hour. The quality of enumeration of plastic waste on the blades before the modification was still not chopped properly, while the results of plastic waste debris on the blades after modified has been chopped well but the results were not irregular. Keywords: Plastic waste, chopping machine, enumeration time, size of enumeration result.

Abstract

Energy is a fundamental need that is increasing every year. Dependence on fossil fuels, such as limited LPG and an increasingly threatened environment encourages the development of renewable energy sources. This study aims to examine the feasibility of rice husk energy potential as an alternative fuel to replace LPG in the South Konawe Regency. A survey was conducted to determine the pattern of rice husk utilization at the community level at several rice milling locations in South Konawe Regency. Data analysis was carried out using data obtained from BPS Southeast Sulawesi and BPS Konawe Selatan Publications (2018-2022). By calculating the estimated energy potential of rice husks and energy consumption of LPG use, and forecasting until 2025 using the Double Exponential Smoothing method from Holt. The results of the data analysis show that the average energy potential of rice husks (2018-2022) is 236,124.56 (GJ), and LPG energy consumption (2018-2022) is 365,625.83 (GJ). For forecasting the energy potential of rice husks in 2025 amounting to 277,863.22 (GJ), and forecasting LPG energy consumption in 2025 of 363,968.39 (GJ). In conclusion, the energy potential of rice husks can distribute around 65% of the total LPG energy needs of households in South Konawe Regency. Keywords: Biomass, renewable energy, rice husks

Abstract

Water transfer in inland areas is still done manually, so we need a water pump with efficiency, technology, economy without the use of electricity and fuel, namely a hydram pump. A hydram pump is a water pump that relies on the momentum of water to raise water. The purpose of this study was to determine the effect of inlet pipe size on pump efficiency, outlet pipe flow rate and the effect of pipe joints on major and minor losses. This research was made with a water source height of 1 m, varying inlet pipes measuring ¾ inch, 1 inch, and 1,5 inch with a length of 5 m, a hydram pump body with a diameter of 1 inch, an air tube with a diameter of 3 inch with a length of 40 cm and an outlet pipe measuring ½ inch. The largest hydram pump efficiency is found in the ¾ inch inlet pipe with 1.94% with an outlet pipe flow rate of 1.79 l/min and the lowest efficiency is in a 1 inch inlet pipe with 1.49% with an outlet pipe flow rate is 1.55 l/min while the major value and the biggest loss value are in the ¾ inch inlet pipe with values of 0.00754 m and 0.678 m and the lowest values are in the 1.5 inch inlet pipe with values of 0.000410 m and 0.019 m so that it can be concluded that the cross-sectional area and the number of connections in the hydram pump installation are very influential on the value of major and minor losses.Keywords: Diameter, Waste Valve, Pipe, Pump

Abstract

This research aims to determine the characteristic briquettes of rice husk and sawdust. The treatment of this research includes non-carbonization processes, composition variation 30 % rice husk, 70 % sawdust powder, 50 % rice husk, 50 % sawdust powder, and 70 % paddy Husk, 30 % sawn wood powder (adhesive material considered homogeneous) as well as pressure variations (50 kgf/cm2, 100 kgf/cm2 and 150 kgf/cm2). The results of these things show that the higher the percentage of rice husk then the combustion time will be relatively longer, composition 50% rice husk and 50 % sawdust powder produces a higher maximum temperature than other composition, the higher the pressure given then the briquette density level will be greater and the resistance level the briquette will be higher and the Resistance index briquette is strongly influenced by the pressure and material composition briquette.
