Abstract

Nowadays, biocomposite materials are required for particular needs. Coconut husk has a potential to be biocomposite using a resin produced by the laccifer lacca kerr (kerria lacca), an insect. This work was aimed to study the use of the lacca kerr resin to produce a biocomposite of coconut coir based. In the experimental, firstly, the cleaned coconut husks were chopped then mixed with lacca kerr resin and alcohol to make a composite dough. Then the dough were pressed with 130 psig at a 100oC within15 minutes. After that, the biocomposite was allowed to ambient temperature, then it properties were observed. To find the best product properties, the ratio of basic materials were varied. The ratio of coconut husk: lacca kerr resin was used ranged from 0.6 g/mL to 1.4 g/mL. The characterization of product properties were carried out based on ASTM D-638 and under guidance of the Indonesian National Standard (SNI) 03-2105-2006. Based on results, it was found that the best biocomposite observed had properties such as density of 0.45 g/cm3 , water content of 8.8% (maximum SNI requirement of 14%), degree of swelling of 67.6%, tensile strength of 43.4 kgf / cm2 (minimum SNI requirement of 3, 1 kgf / cm2 ), Young's modulus of 1219.2 kgf/cm2 , elongation of 67.7%, conductivity of 1.8 10-8 /.m. Some of these characteristics have met the Indonesian national standard (SNI).

Abstract

Ceramic and glass particle waste is generated in large quantities as a result of their extensive use in various applications. Inappropriate disposal of the waste can lead to environmental degradation and health hazards. This research utilizes ceramic and glass wastes as drilling cement additives in the oil and gas industry. The objective of this research is to study the effect of adding ceramic and glass waste on the properties of drilling cement, including compressive strength, shear bond strength, and thickening time. With composition percentage ratios of 10%, 20%, 30%, 35%, and 40% by weight of cement, the slurry was poured into 1.2x2 inch cubic molds to test compressive strength and into 1.2x2 inch cylindrical molds to test shear bond strength. The findings of this study indicate that the addition of ceramic and glass waste as a drilling cement additive has a positive effect on compressive strength, shear bond strength, and thickening time and is also effective for use as an alternative additive in drilling cement operations

Abstract

This study examined the feasibility of using locally sourced bentonite as drilling mud, with the aim of reducing the cost of imported drilling mud. Bentonite, a soil type containing a high concentration of smectite or montmorillonite, is widely used in drilling mud. The physical properties of drilling mud made from bentonite from Boyolali and Tulungagung were compared, with the addition of various additives to meet the API 13A standard. The research found that drilling mud made from Boyolali bentonite showed physical properties that were closer to the API 13A standard compared to Tulungagung bentonite. Specifically, adding 7 grams (12%) of polyamine to Boyolali bentonite mud produced a volume of filtrate loss and mud cake thickness closest to the API 13A standard, namely 10.8 ml (maximum 15 ml) and 0.14 cm (maximum 0.28 cm), respectively. Adding 2.3 grams (5.04%) of KOH resulted in the highest pH value of 13, while adding 2.5 grams (1.17%) of Na2CO3 produced the least amount of filtrate loss, namely 7.2 ml (maximum 15 ml), with a mud cake thickness of 0.27 cm (maximum 0.28 cm)
