Chili is one of the important food ingredients. The lack of public knowledge about chili cultivation techniques and good land optimization makes people's interest to grow chili less. In addition, household organic waste management in Tasikmalaya, especially in Sukasari Village, has not been optimal. The objectives of this service activity are 1) To provide knowledge and skills about chili cultivation techniques; 2) Utilization of household organic waste through the technology of processing household organic waste into organic fertilizer that can have economic value (Osama biobased economy); and 3) Educate the public regarding the optimization of yard land. The partners in this activity are the Jaya Mukti Farmers Association and Mukti Farmers Group which are located in adjacent areas with a total of 32 people using a random sampling technique because the sample is homogeneous. The activities carried out were in the form of socialization, demonstration, and practicum on household organic waste processing technology (Osama), chili cultivation techniques and optimization of yard land, as well as distribution of seeds and fertilizers to the community. The data collection technique in this activity uses a questionnaire. The results of this service activity indicate that there is an increase in community knowledge and skills in chili cultivation and the use of household organic waste and home yards.

Metacognitive skills are required for students to manage and keep track of their understanding of fact-finding and concept-building by scientific process skills. This research aims to determine the correlation between metacognitive skills and students' scientific process skills on cell-based bioprocessing topics. The population of this study were all class of XI MIPA in one of SMA Negeri Kota Tasikmalaya. The research samples were 30 students from class XI MIPA 2 selected based on the purposive sampling method. The research instruments used contained an essay test consisted of 21 questions with indicators developed by Tawil and Liliasari to examine the scientific process skills. In contrast, the questionnaire adapted from the Metacognitive Awareness Inventory consisted of 50 positive statements with 4 Likert-scale-based alternative answers to examine the metacognitive skills. The normality and linearity test are conducted before performing the hypothesis test as a prerequisite. The hypothesis testing based on bivariate correlation and regression with an α of 0.05 showed a positive correlation between the two variables. The correlation coefficient with a value of 0.544 represents a moderate correlation between the two variables. The determination coefficient shows the contribution of 29.6% from the metacognitive skills in students' scientific process skills on cell-based bioprocessing topic.

<p>Critical thinking skills is a most important aspect that must be owned by students in biology learning, especially in solving the problems that require alternative in-depth solutions and close to the problems that we are often encountered in daily life. This research aims to determine the correlation between student’s critical thinking skills and learning outcomes on the topic of human musculoskeletal system. The method for this research was correlational study. The research’s populations were all of grade 10 MIPA Senior High School in Tasikmalaya with characteristics discipline and have a lot of achievement in academic and nonacademic. The sample was 48 students from grade 10 of MIPA 4 selected based on cluster random sampling method. The data were gained by giving the essay test consisting of 15 analysis questions with indicators developed by Ennis to measure student’s critical thinking, and 35 multiple choice questions to measure student’s learning outcomes. Data analyzed by correlation and regression analysis Pearson product moment with significant level (α) 0,05. The normality and linearity test are conducted before performing the hypothesis test as a prerequisite. The result of research, data analysis, and hypothesis testing reveals that there is a positive correlation between student’s critical thinking skills and learning outcomes on the topic of human musculoskeletal system with correlation coefficient obtained is 0,667 it’s mean have a high correlation category. Contribution of critical thinking skills toward learning outcomes is 44,5% while 55,5% is influenced by other variables that are not researched.</p>
