This study aims to describe the description of learning independence, students' creative attitudes, and the relationship between learning independence and students' creative attitudes towards learning outcomes in class X chemistry learning at SMA Negeri 6 Palu. This research was conducted from April to June 2021. The research method used was descriptive research. The sampling technique is purposive sampling. The population in this study were all students of class X with a total of 90 students, the samples used were students of class X IPA 2 SMA Negeri 6 Palu in the academic year 2020/2021 as many as 30 students. The research instrument used in this study was a learning independence questionnaire and a creative attitude questionnaire compiled using a Likert scale, and using MID learning outcomes in semester 2 of chemistry class X IPA 2. Based on the results of the study, there were 3 categories of descriptions of independent learning and creative attitudes students are high, medium and low. The results of the calculation of the correlation coefficient between learning independence and student learning outcomes are low (rcount) 0.260. The relationship between creative attitudes towards student learning outcomes is moderate (rcount) 0.457 at the moderate level. Based on these data, it can be concluded that the creative attitude of students to support learning success is more positive than student learning independence. The results of this study are expected to be a source of information regarding the relationship between learning independence and students' creative attitudes towards learning outcomes

The research location is in the Saluki Lore Lindu National Park, Central Sulawesi Province. The study took place in March-December 2021. The findings targeted in the study are: (1) Information on egg-laying behavior, (2). When laying eggs, (3) After laying eggs, (4) Determining the length of time for laying eggs, (5) Physical characteristics of the nest and vegetation. The research method used the survey method. Observations of maleo bird activity were carried out every day for 3 months in the egg-laying season from May to July. The results showed that the physical condition of the average nest depth was 67.78 cm, the average nest width was 52.78 cm, the average nest temperature was 33.44°C, the nest humidity was 76.11% and, the soil acidity (pH) with an average of 6.35. The vegetation found at the nesting site consisted of 18 species. The maleo maleo bird's egg-laying behavior activities are playing, snooping (observation), and making a trick hole. There were four activities of female maleo bird laying behavior, namely playing, digging holes for laying eggs, lurking, making trick holes and laying eggs. The duration of time needed by male maleo birds when playing, snooping, making holes, until the female finishes laying eggs, which takes 92 minutes. While the female takes 84 minutes.

This study aims to explain the effect of tofu waste as liquid organic fertilizer on the growth and production of tomato plants (Lycopersicum esculentum) and its use as a learning media in the form of posters. This research was conducted at the Green House Biology FKIP UNTAD from November 2020 to February 2021. The method used was an experimental method with a completely randomized design (CRD) one factorial experiment consisting of 4 levels of treatment (P0 = control, P1 = 200 ml, P2 = 400 ml, P3 = 600 ml) and 3 replications. Parameters observed in this study were plant height, number of leaves, number of branches, number of fruits, and stem diameter at 15 DAP, 30 DAP, 45 DAP, and 60 DAP. The calculated parameters were the number of fruit and fruit weight at 60 DAP. The results of this study showed that the best growth and production was P1 treatment with a dose of 200 ml of liquid organic fertilizer tofu waste. This can be seen in the analysis of variance for each parameter, namely plant height with Fhit 4.90 > Ftab 4.07, number of branches Fhit 8.14 > Ftab 4.07, number of leaves Fhit 7.13 > Ftab 4.07, stem diameter Fhit 12.92 > Ftab 4.07, number of fruit values Fhit 11.83 > Ftab 4.07, and the weight of the fruit is Fhit 11.36 > Ftab 4.07, then H0 is rejected and H1 is accepted. Thus, it can be concluded that liquid organic fertilizer from tofu waste can affect the growth and production of tomato plants with the best dose of 200 ml at 60 DAP. Based on the validation test and has been tested on students, the overall results of the study are very feasible to be used as learning media with an average percentage of 81.84%.

The purpose of this study is to describe the completion of arithmetic operations, multiplication and division of algebraic forms for students of SMP Negeri 18 SPMI Palu. This type of research is qualitative research. The subjects in this study were 2 students taken from 32 grade VIIA students of SMP Negeri 18 Model SPMI Palu. The results of this study indicate that the completion of students with high mathematical abilities in solving arithmetic operations problems of multiplication and division of algebraic forms, namely: (1) ST writes the given problem, changes the problem using distributive properties so that the results are obtained. But on the results of the ST distributive property, they did not write down the number sign because they forgot to write it down. Then perform multiplication operations, add up similar terms and get the final result, (2) ST writes down the questions given, performs tiered division operations so that the results are obtained. Completion of students with low mathematical ability in solving arithmetic operations problems of multiplication and division of algebraic forms, namely: (1) SR rewrites the given questions, grouping similar terms, operating like terms so that the results are obtained. However, SR incorrectly determines the result of an integer operation. This is due to SR's inaccuracy when operating, (2) SR wrote questions, did not perform tiered division operations so that the results were obtained.
