Abstract

Coffee liquid waste contains organic matter which can be at risk of increasing water pollution levels. The results of the preliminary research carried out showed that the level of pollution due to coffee liquid waste exceeded the quality standard, with the results of the BOD test results being 23 ppm and COD 72 ppm, so we need a way to reduce pollution. Phytoremediation is a method of natural waste handling using certain plants in collaboration with microorganisms in the media (soil, coral, water) so that it can change contaminants to be reduced or harmless. This study aims to determine the effectiveness of Salvinia molesta phytoremediation in reducing BOD and COD levels. The research design used a completely randomized design (CRD) with four treatments with three replications. The research data were tested using the Analysis of Variety Prints and the Duncan's Multiple Distance Test continued test. The results showed that the effectiveness of Salvinia molesta in reducing BOD levels was found in P3 obtained by an average of 8.37 ppm (73% decrease) and reducing COD levels by an average of 25.37 ppm (73%). Based on these results, it can be concluded that P3 is effective in reducing BOD and COD levels of coffee liquid waste.

Abstract

The change in learning which was originally face-to-face turned into distance learning suddenly and simultaneously this certainly caused various obstacles for teachers in the learning process. This study aims to identify the teacher's obstacles in the Distance Learning System in Biology learning at Senior High School  of Brebes Regency during the COVID-19 pandemic. The study used descriptive qualitative methods by distributing online questionnaires to the teachers. The population in this study were Biology teachers at Senior High School in Brebes Regency, totaling 36 teachers. Sampling used a total sampling consisting of 36 teachers. The instrument used is a teacher's questionnaire in planning, implementing learning, design, and learning media, learning technology/application, and assessment/evaluation. The instrument in the form of a teacher questionnaire used has been validated by researchers with expert validation. The results of the study indicate that the most dominant constraint is the constraint in the very high category, namely the planning constraint of Distance Learning System (68%) Followed by the implementation constraint with a percentage (62%) in the high category then the assessment and evaluation constraint with a percentage (61%). Meanwhile, other constraints are design and media constraints by 60% in the high category and technology/application constraints by 60% in the high category. Referring to these results, teachers in the Distance Learning System still find problems in planning, implementation, media and methods, technology/application, and evaluation/assessment. One of these obstacles must be overcome, one of which is to overcome obstacles in technology/application, namely by replacing the easier-to-use learning media, namely GoogleMeet, or Zoom Meeting, where both applications include official applications supported by the Ministry of Education and Culture in subsidizing internet quotas.

Abstract

Assessment is an integrated part of the planning and implementation process of learning. The transition from KTSP to the 2013 curriculum is a problem for teachers in applying assessment skills in learning, because teachers still have difficulty implementing authentic assessments and still use assessments in terms of cognitive tests only (Setiadi, 2016). This study aims to determine the literacy profile of science teacher assessments at SMA Negeri 1 Gubug and the assessment used by science teachers. This is because there is no source of research on teacher awareness of assessment in SMA Negeri 1 Gubug. This research uses descriptive quantitative research method, with purposive sampling. The instruments used in this research are the assessment literacy test, interview guidelines, questionnaires, and check list sheets. Based on the results of data analysis and discussion, it can be concluded that the assessment literacy profile of science teachers at SMA Negeri 1 Gubug is based on PAP Type II is in the "Very Low" category (assessment literacy questionnaire) and "Low" category (interview results). The teacher has the highest score with a score of 86% on the aspect of the difficulty of using the assessment, while the lowest score is on the aspect of attitude assessment by getting a score of 18%. The implication of this study is that by knowing the literacy assessment profile, teachers can understand and implement the importance of assessment so that this can be used as a benchmark in improving the quality of learning.
