Abstract

Competition in the manufacturing industry demands products with high quality and high productivity too. Machining parameters such as cutting angle, cutting speed, and feed speed determine the rate of material works or the rate of material removal (MRR) of the lathe process. Determination of excessive machining parameters will reduce productivity because there is a product that must be reworked. This research will specifically emphasize the lathe process with medium carbon steel workpieces. The problem is how to specify its cutting speed, feed speed, and the primary cutting angle in the lathe process with a medium carbon steel workpiece that will produce a smooth surface of the lathe on the product. The workpiece used in the experiment is ST 60 steel dimensions Ø30 mm x 200 mm with a chuck-tailstock spindle gripping system. The results showed that the ST-60 steel lathe process without followers, with the primary cutting angle machining parameters Kr = 45°, cutting speed 60.5 m /min, feeding speed 44.66 mm/min, and at a depth of cut 0.2 mm obtained surface roughness value 3.72 μm or N8 roughness level. As for the primary cutting angle machining parameters Kr = 90°, cutting speed 60.5 m/min, feeding speed 22.33 mm/min, and at a depth of cut 0.2 mm, the surface roughness value 3.69 μm or N8 roughness level is obtained.

Abstract

The utilization of biomass as an alternative to reduce dependence on fossil energy can be done through briquette technology. Through this technology, alternative energy sources can be obtained with high heating value and easy storage. The current promising source of biomass is sawdust and coconut shell waste because it is available in abundant quantities. This abundant amount has not been optimally used, because it only tends to be burned. Through briquette, technology is expected to increase the added value of waste. Briquette quality is influenced by several factors, one of which is the particle size of charcoal powder. The purpose of this study was to determine the effect of particle size of charcoal powder on the content of fixed carbon and volatile matter on charcoal briquettes. The research method was carried out by varying the particle size of charcoal powder, 10 mesh, 20 mesh, and 40 mesh. The research was carried out in several main stages, there are charcoal (carbonization), particle size reduction (grinding), sieving, mixing of raw materials, molding, drying, and testing of charcoal briquettes. The results showed that the charcoal briquettes produced had an average fixed carbon content of 58.761% and a volatile matter of 33.675% at 10 mesh charcoal powder particle sizes. At a particle size of 20 mesh, it produces charcoal briquettes with an average fixed carbon content of 60.491% and a volatile matter of 31.333%. While at 40 mesh, it produces charcoal briquettes with an average fixed carbon content of 59.216% and a volatile matter of 30.561%. The research results obtained further reinforce that the charcoal briquettes produced are feasible to be developed.

Abstract

The use of biochar and NPK fertilizers in an effort to overcome the problem of inefficiency in using excessive fertilizers on the fertility of nutrients in the soil. This is because nearly 40-70% N, 80-90% P, and 50-70% K are lost to the environment without being absorbed by plants which results in leaching, degradation, and evaporation of volatile materials in the soil. The purpose of this study was to obtain the efficiency of the results of starch coating on the mixture of corncob biochar with NPK fertilizer through a coating method which functions to bind the content of biochar and NPK fertilizer which has been coated with starch in the soil so that it does not evaporate easily when exposed to sunlight and also so that fertilizer is more hold for a long time so that it is not easily carried away by water erosion. The variables determined were NPK fertilizer content of 10%, 20%, and 30% of the weight of the corncob biochar and the concentration of starch as a coating of 10%, 20%, and 30%. The results obtained in this study were the lowest percentage value of coating was obtained, namely 0.4256%, and the highest dissolution rate was obtained at 3600 seconds. The optimization value obtained in the Minitab analysis is at 10% NPK with a 30% starch concentration with a desirability value of 0.4983. Thus, it can be concluded that the efficiency of starch coating on biochar greatly affects the percent coating and the resulting dissolution rate.

Abstract

Indonesia is a country with large population growth. The increasing number of occupations resulted in an increased need for food. One of the efforts made to meet these needs is by increasing agricultural yields such as fertilization and farming to maintain soil fertility to obtain optimal agricultural yields. The use of corn cobs and NPK biochar has an adverse effect on plants due to changes in pH in the soil, and about 20-70% of fertilizers are degraded or washed away by groundwater, so fertilization is ineffective and efficient and will pollute the environment with N content, P and K. This study aims to analyze the ash content of corn cobs biochar with NPK fertilizer using the coating method. The coating is a process for coating material by wrapping, soaking, or spraying it to provide resistance to the material and provide protection against the material. The raw material used is corn cobs biochar. The variables determined were a mixture of biochar and NPK fertilizer: 10%, 20%, and 30% with starch concentrations of 10%, 20%, and 30%. The results of the analysis obtained the lowest ash content value with the composition of biochar and NPK with a concentration of 10% coated with starch with a 30% concentration of 0.0557%. While the highest ash content was in the concentration of biochar and NPK with a concentration of 30% with a concentration of 10% starch at 0.1353%.
