Abstract

[Title: The Mechanical Test of Lightweight Brick Made from Gold Processing Waste with Variations in Coal and Cement Waste]. The purposes of this research are to make lightweight concrete using waste processing of gold with variation fly ash and cement the better than conventional concrete. The value of this research has tested mechanics which comprises density, porosity and strength. The research has done with some stage are: 1) Make lightweight concrete using LPE with variation fly ash and cement. 2) Characterization of the samples which comprise density, porosity and the strength, 3) Analysis of tested mechanical lightweight concrete. The value of lightweight concrete to make with variation composition fly ash and cement in a series are: (0/100), (5/95), (10/90), (15/85), (20/80) who are in volume. To make lightweight concrete with composition foam and water controlled as much as 10 ml and 150 ml at all of the sample. So we get the density value of lightweight concrete without fly ash is 1.61. In lightweight concrete with fly ash, we get the minimum density of lightweight is 1.15. The porosity value of lightweight concrete without fly ash is 13.6%, and the porosity value of lightweight concrete with fly ash is 8.0%. The compressive strength of lightweight concrete without fly ash is 1.629 MPa and the compressive strength of lightweight concrete with fly ash is 1.772 MPa. The value shown to process waste processing of gold with variation fly ash and cement to be lightweight concrete can get mechanical in character of lightweight to be better than conventional concrete.

Abstract

The purpose of this KKN-PPM program is to accomplish a problem from cattles waste that has not been managed properly. Further management is directed towards making small-scale biodegesters into energy-independent villages. This devotion is implemented in Kidang Village of East Praya in Central Lombok Regency. The availability of an abundant source of cattle dung is spread in each private cowshed (there is no collective cowshed) because of the distribution pattern of Kidang Village residents in small groups, supporting the implementation of this program. The soil texture of cracked clay in the dry season, as well as the limitations of the water source cause the degister model are suitable for the condition. Degister applied is a small-scale biodegister, designated for 1 family with the number of cattle at least 2 cattles (cow). Biodigester is installed in 6 different location as a pilot program to Kidang Village community. Digester uses a 1200 liter plastic tank, with in let, out let, and out putt gas using a piping system. The digester is filled with ¾ part of the cattle dung, and ¼ of the part as the gas reservoir. The gas produced from the digester model shows a mixture of water : cattle dung with a 2: 1 ratio is faster than the 1: 1 mixture. In the mixture with a ratio of 2: 1, the gas has begun formed on day 11 with increasing pressures day by day, with the pressures of 73.26 Pa, 106.36 Pa, and 112.00 Pa.

Masing-masing geometri dicetak dengan variasi tekanan 10 PSI, 20 PSI, dan 30 PSI. Hasil penelitian menunjukkan bahwa briket dengan bahan dasar abu sekam padi menghasilkan kalor yang lebih tinggi dibandingkan dengan briket berbahan dasar eceng gondok. Geometri pelet briket berongga menghasilkan kalor yang lebih tinggi dibandingkan dengan briket pejal. Geometri kotak berongga mengasilkan kalor terbaik dibandingan dengan geometri tabung pejal. Tekanan optimum dalam pembuatan pelet briket dihasilkan pada tekanan 20 PSI. Kata kunci: briket; eceng gondok; abu sekam padi; oven tembakau. ABSTRACTThe purpose of this research is to produce briquettes as an alternative fuel for tobacco ovens. There are two briquettes produced, namely briquettes made from water hyacinth and briquettes made from rice husk ash. The two briquettes were made with a variation of the composition of 10% tapioca starch adhesive and 90% base material to get the best briquette results to be applied as an alternative material in the community tobacco oven process. In addition to variations in the basic material, variations in pellet geometry were also carried out, which included solid boxes, hollow boxes, solid tubes, and hollow tubes. Each geometry is printed with a pressure variation of 10 PSI, 20 PSI, and 30 PSI. The results showed that briquettes made from rice husk ash produced higher heat than water hyacinth briquettes. Hollow briquette pellet geometry produces higher heat compared to solid briquettes. Hollow box geometry produces the best heat compared to solid tube geometry. The optimum pressure in the manufacture of briquette pellets is produced at a pressure of 20 PSI. Keywords: briquettes; water hyacinth; rice husk ash; tobacco oven.
