Abstract

Penelitian ini bertujuan membuat Briket Bio-coal berbahan campuran limbah batubara dan biomassa rumput melalui proses karbonisasi beserta karakterisasinya. Briket Bio-coal dibuat dengan Limbah Batubara Sisa Preparasi (LBSP), Limbah Batubara Sisa Uji Proximate (LBSU), Sisa Pemotongan Rumput (SPR) yang dikarbonisasi, dan menggunakan perekat Tepung Tapioka (TT). Berdasarkan hasil analisa didapatkan semakin banyak komposisi limbah batubara maka akan menghasilkan nilai kalori yang tinggi. Kondisi optimum didapatkan pada sampel dengan komposisi 60LBSP:30SPR:10TT dengan nilai kalori 5311 cal/gr, kadar air 3,13%,  kadar abu 16,78%, kadar volatil matter 42,53%, kadar fix karbon 37,55% dan nilai densitas 0,90 gr/cm3, serta 60LBSU:30SPR:10TT dengan nilai kalori 4844 cal/gr, kadar air 5,32%,  kadar abu 19,05%, kadar volatil matter 36,78%, kadar fix karbon 38,85% dan nilai densitas 0,97 gr/cm3.

Abstract

The Eco Green Campus Program adopted by Sepuluh Nopember Institute of Technology (ITS) aims to create a campus that is sustainable and environmentally friendly with a focus on cultivating healthy organic soil. However, tillage Organic soil require organic materials which are quite expensive and difficult to obtain, such as organic fertilizer. Therefore, innovative solutions are needed through utilization of abundant local resources such as remaining coal samples with compost that called Green Coal which was made into quality organic soil enhancer. Coal has very complete nutrients and can be used as fertilizer. In addition, the use of coal as fertilizer can reduce the potential for degradation of the quality of agricultural land. In order to meet the needs in ITS parks, coal from the rest of the laboratory testing samples can also be used as a source of soil fertilizer. However, the results of the production is still lacking by number so sometimes the compost is applied though its still half ripe. To increase its effectiveness, organic compost waste is used as a soil conditioner through the use of coal. ITS has succeeded in developing a soil enhancer product named Green Coal from residual coal sample. However, the process of making Green Coal is done manually and is constrained by time constraints. Therefore, in this research, a 3-in-1 Green Coal machine was carried out to increase the efficiency of Green Coal production. The 3-in-1 Green Coal machine consists of a chopping machine, a sieving machine and a mixing machine in one machine so it can simplify processes, cost and time efficiency in the production process. The results of this research showed that a 3-in-1 Green Coal machine can produce 10 kg/minute of Green Coal soil enhancer products.

Abstract

This study synthesizes the literature on positive self-talk in adolescents. The research aimed to comprehensively understand descriptive forms and strategies to increase positive self-talk in adolescents. The method used in this research was Systematic Literature Review (SLR) by searching relevant articles through Scopus, Taylor & Francis Group, and Sage databases. The search was limited based on predetermined inclusion criteria, and 30 articles were obtained by peer review. The research design used was Preferred Reporting Items for Systematic Reviews and Meta-Analytics (PRISMA). The results demonstrated that the form of positive self-talk in adolescents varies and can be applied to cultivate self-talk habits that are goal-directed, rational, affective, cognitive, motivational, and have psychological functions. Strategies to improve self-talk include using gestures through repetitive practice, mental rehearsal, cognitive interventions, and using first or second-person pronouns. Furthermore, strategies to increase self-talk can be implemented using video modelling examples and naturalistic videos.
