Abstract

In the era of the industrial revolution 4.0, the education system has used technology to assist the learning process. Technology-based learning makes it easy for students and teachers to carry out learning activities. However, teachers have not been able to optimally develop students' potential, low student learning outcomes and low problem-solving abilities in students. Problem solving ability is very important for a student in learning science. Problem-solving skills in science learning are the main key to training students' scientific thinking in solving phenomena in science. So, it is necessary for a teacher to improve the learning model for those who are able to develop students' problem solving abilities. Problem solving learning is a learning model based on problem solving. In addition, the problem solving learning model helps teachers to be more creative in carrying out the teaching and learning process. This study aims to analyze the effect of problem solving learning models on students' problem solving abilities in science learning. The data source for this research comes from an analysis of 30 national or international journals that have been published from 2010-2022. The search for data sources came from the Google Scholar, ScienceDirect, Emerald, Eric, Springer, Hindawi, ProQuest, Sage Journal, Wiley and Taylor of Francis databases. Sampling in this study was carried out by using purposive sampling technique. The data that can be used is related to the research variable. Furthermore, the research data search keywords are problem solving learning models, problem solving skills and science learning. Data analysis is a descriptive quantitative analysis technique with the help of the OpenMEE application. The results of the study concluded that the problem solving learning model had a significant influence on students' problem solving abilities in science learning with an effect size of 1.808, an average value of 83 and a standard deviation of 0.45

Abstract

This study aims to examine the effect of fertilizer concentration on the growth of land kale. The research method chosen was a simple completely randomized design (CRD).The plant samples consisted of 6 groups, each consisting of 5 plants, with 1 group as the control group and the remaining 5 groups as the experimental group. The experimental group was treated with varying concentrations of liquid fertilizer from 2.44% by volume, 4.76% by volume, 6.98% by volume, 9.10% by volume up to 11.11% by volume and observations of plant growth were carried out once every 4 days for 5 period. Based on the plant height results, the experimental group produced the highest average plant in sample E with a concentration of 11.11% by volume. As for the number of leaves parameter, the highest number of leaves was also obtained in the experimental group sample E. Based on the results of analysis of variance using the Anova Test, it was found that the results of Fcount>Ftable were good in the analysis of the effect of fertilizer concentration on plant height and number of leaves. So that the use of liquid fertilizer has a significant effect on the growth of land kale (Ipomea reptans. Poir).

Abstract

This study aimed to determine the effect of giving Infarm POC concentration variations on the growth of green mustard (Brassica juncea L). The research employed a completely randomized design (CRD) or randomized block design with 6 treatments and 5 replications, resulting in a total of 30 experimental units. The data collection method and mechanism used involved implementing a completely randomized design (CRD) with 6 types of treatment and 5 replications, leading to the cultivation of 30 mustard plants with POC concentrations ranging from 2% to 10%. The findings revealed that the application of POC fertilizer to mustard plants resulted in increased plant height, leaf count, and resistance to leaf pests. Notably, the POC concentration of 6% exhibited the most significant improvements in plant height and leaf count. However, to gain a more comprehensive understanding of the effectiveness of this POC, further research is necessary. It is recommended to extend the duration of the study until harvest to assess the weight and quality of the mustard greens, thereby providing more conclusive insights

Abstract

The objective of this study was to investigate how distillation temperature affected the specific gravity (SG) and calorific value of bioalcohol derived from breadfruit peels (Artocarpus altilis) as an alternative fuel. The process of producing bioethanol from breadfruit peels begins with pretreatment of the peels, followed by hydrolysis with hydrochloric acid, fermentation, and finally distillation. The hydrolysis process used 20% hydrochloric acid in a volume of 25 ml, and the fermentation took 6 days with a mass of 30 gr of yeast Saccharomyces cerevisiae. The distillation process lasted two hours, with temperatures varying between 70, 80, and 90°C. This study yielded the highest alcohol content of 72.80% at 70°C and the highest volume of bioalcohol of 35.67 ml at 90°C. Meanwhile, the best Specific Gravity (SG) at 70°C was 0.8393. Furthermore, the calorific value test results revealed that the calorific value increased with increasing alcohol content. The highest calorific value obtained was 23003.406 J/gr, which was close to the ethanol calorific value of 29700 J/gr, while the lowest calorific value obtained was 22339.008 J/gr at a distillation temperature of 90°C

Abstract

This research is a qualitative research whose background is that there are still some students who still do not reflect Pancasila behavior both during learning and outside of learning. This study aims to analyze character strengthening through the application of Pancasila values ​​in thematic learning of science content at SDN 008 Samarinda Ulu. The technique used in this triangulation is triangulation of data sources to test the validity of the data. The results of research that has been carried out by researchers in class IVB SDN 008 Samarinda Ulu is that the teacher has applied Pancasila values ​​in the thematic learning of science content so that it influences student character. Its application is by getting students to pray, say hello, greet. The teacher gives freedom to students to express opinions, respect differences, help others, consult, and be fair when learning takes place which is integrated with strengthening religious, national, independent and mutual cooperation characters. There are no difficulties in strengthening character through the application of Pancasila values ​​in thematic learning

Abstract

The golden snail is a pest that causes crop failure in rice plants. Farmers control the golden snail by using pesticides, which can have a negative impact on the environment, so another alternative is needed that can control the golden snail, namely vegetable pesticides. This study aims to determine the effect of a combination of oleander leaf extract and neem leaves on the mortality of Keong Mas. The method used in this research is the experimental method with a factorial completely randomised design (CRD). The study consisted of 2 factors, namely factor N (Oleander leaf) and factor A (Azadiracta indica leaf), each of which had 4 levels, so there were 16 treatment combinations and 3 replications. There were 480 golden snails in the study. After 12 hours of observation, the N3A3 treatment tested by ANOVA showed significantly different results (fcount > ftable = 66.00 > 2.01) and caused 30 test animals to die with a mortality rate of 77%.  The conclusion from this study is that the combination of oleander leaf extract with neem leaves greatly influences the mortality of the golden snail

Abstract

Experiments have been successfully carried out to react with lactic acid and 1,4-butanediol, tin (II) chloride dihydrate (SnCl2.2H2O), chloroform, methanol, liquid nitrogen, nitrogen gas, and silicone oil at various concentrations. The objective exists to synthesize polylactic acid by forming polylactic acid diol (PLA-OH) via a direct polycondensation reaction of lactic acid and 1,4-butanediol in a glass reactor following a specific reaction scheme. Synthesis was carried out using different amounts of reagents according to the predetermined mole ratio of lactic acid (AL) and 1,4-butanediol (BD). The FTIR, 1H NMR, and GPC analyses that characterized the PLA-OH revealed its physicochemical characteristics. The FTIR and 1H NMR characterization results show new absorption peaks and a shift in PLA-OH absorption peaks. It indicates that a bond has been formed from the reaction between lactic acid molecules and 1,4-butanediol to produce PLA-OH. From the spectrum analysis, it can be concluded that the structure of the synthesized PLA-OH has four different proton environments (there are four different peaks in the spectrum). The peaks originate from the protons in methylene (-OCH2CH2CH2CH2O), internal methine (-O-CH-), and methine at the end of the PLA-OH chain, as well as proton peaks in methyl (H3C-). The characterization results with GPC showed that the tendency to increase Mn PLA was directly proportional to the increasing amount of lactic acid in the PLA chain
