Abstract

Cassava skin waste is waste originating from cassava plants from tapioca flour factories or cassava processed product factories. Indonesia is one of the biggest countries that produces cassava. The number of cassava processing industries in Indonesia is large so that a positive correlation can be drawn that the high amount of cassava processed will produce more cassava skin waste. Based on the results of tests conducted, the higher the composition of the Each cassava can produce 10-15% of cassava skin waste. Cassava skin waste is directly removed, can cause buildup that results in environmental damage. Cassava skin waste is obtained from local farmers, where on average each cassava produces 10-15% of waste. In general, this waste is not used and just thrown away. This research was conducted with the main ingredients of cassava peel waste and adhesive made from used paper. The composition of the mixture of cassava peel and used paper varies, where the percentage by weight of the adhesive starts from 7.0% to 10% with an increase in the composition every 0.5%. Then the biobriquette carbonization process was carried out at a temperature of 400 ° C. The biobriquette characterization was carried out based on ASTM standards to analyze water and ash, volatile matter and heating value. The results of the analysis on the composition of the lowest cassava bark had the highest heating value of 5888 cal / gr with the lowest water, ash and volatile matter content.

Abstract

This study presents a case study investigation on failure analysis of drill pipe during the drilling operation and to establish a general understanding of fatigue failure with experiments and several tests. Drill pipe load comprises tensile, compression, bending, hydrostatic pressure and vibration, which causes damage due to fatigue failure to the drill pipe. The method involves subjecting a 2 in length and nominal diameter 3.25 in connection NC50 19.5 ppf drill pipe to predetermined caused failure by experimental tests and analysis. Mechanical examination such as tensile test and hardness test, and metallurgical examination such as spectrometry, fractography, SEM and EDX testing are conducted. The result shows that the cause of failure on the thread drill pipe was due to fatigue failure. It showed by the presence of microcracks, which accumulated from the load in the drill pipe. In addition, propagation of the crack at critical depth resulting in failure during drilling operations.

Abstract

Cassava peel waste in large quantities can harm the environment. Cassava peel waste can be used as a renewable energy feedstock since it is environmentally friendly biomass converted into bio briquettes for use as an alternative fuel. The advantage of cassava peel can positively impact the environment while also adding value to the cassava peel. Cassava bio briquettes produced with water hyacinth and banana leaf stem were compared in this study. Temperatures of 300°C, 350°C, 400°C, 450°C, and 500°C are used to discover the best conditions for briquettes, with a carbonization time of 45 minutes. Bio briquettes can be made from water hyacinth and banana leaf stalks, according to the analysis. The best results were achieved at 400°C carbonization temperature, with a calorific value of 5461 Cal/g for water hyacinth adhesives and 5265 Cal/g for banana leaf stalk adhesives.
