Abstract

The rapid development of technology today cannot be separated from the role of various kinds of machines to produce or increase the use value of an item. The more the engine operates, the more lubricant is used. Lubricants are included in the category of B3 waste (Toxic Hazardous Materials) so that they have a negative impact on the environment. Nearly 50% of all mineral lubricants enter the environment and cause irreparable environmental damage due to direct contact with water and soil. One of the efforts that can be done to reduce the B3 content in used lubricants is adsorption using a porous adsorbent. This study aims to see the relationship between the physical and chemical properties of the adsorbent with the physical and chemical properties of the adsorbate. This research was conducted by studying the literature of scientific articles with related topics. The results showed that some contaminants such as organic compounds, inorganic species, soot, hydrocarbons, and ash can be adsorbed with various adsorbents, namely modified sawdust, bentonite, fly ash, activated carbon, activated alumina, and zeolite Y derived from kaolin.

Abstract

This research aims to determine collaboration skills profile of class 11 students at one of the public high schools in Paciran Regency. The reason for conducting this research is collaboration skills are one of the 21st century skills that must be mastered by students. The research conducted was descriptive quantitative with a cross-sectional survey method. The population of this study was 100 students. The sampling technique used purposive sampling technique with consideration from chemistry teachers. Collaboration skills are measured using an observation sheet containing statements according to aspects of collaboration skills. Data analysis techniques using MS Excel.  Collaboration skills aspect score data was analyzed quantitatively, then converted according to calculations into the very low, low, medium, good, and very good category. The student collaboration skills profile in this research includes 8 aspects are finding solutions, responsibility, mutual respect, interdependence, cooperation, communication, listening to other people's ideas, and commitment. In this research, it was found that the best aspect of collaboration skills in the very good category was the aspect of positive interdependence at 84.30%, cooperation at 88.50% and communication at 91.00%. The research results show that the average percentage of collaboration skills for all aspects is 83.50% and is in the good category.
