This study aims to determine the effect of the Problem Based Learning (PBL) model on students’ problem-solving abilities in the reaction rate material at SMA Negeri 07 Gorontalo. The research employed a quasi-experimental method with a pretest-posttest control group design. The subjects consisted of two classes: class XI1 as the experimental group (using the PBL model) and class XI2 as the control group (using conventional learning). The instrument used was an essay test based on problem-solving indicators. The results showed a significant improvement in problem-solving ability in the experimental class compared to the control class. The average posttest score of the experimental class was 74 (categorized as good), while the control class scored 52 (categorized as fair). The t-test results indicated a significant difference between the two groups (p < 0.05), suggesting that the PBL model is more effective in enhancing students' problem-solving abilities than conventional learning methods.  

This study aims to obtain the validity of E-LAPD using the Problem Based Learning (PBL) model that can be used to improve science literacy on chemical equilibrium material. The design used is a 4-D model designed to improve students' science literacy skills. The valid E-LAPD was evaluated through a validation sheet filled in by the validator using a Likert scale. Validity consists of construct validity which includes presentation components, graphic components, suitability of models and indicators to be improved and content validation which includes the suitability of learning objectives with learning outcomes and the suitability of problems or phenomena with the material being taught.  The validity of E-LAPD is declared valid if the score from the validator is at least 4 and does not have one score < 3 from the validator. The results showed that the E-LAPD developed had high validity indicating that the mode score of the validator ≥ 4. The developed E-LAPD was declared valid for use with a construct and content validation assessment which was described as valid with a score of 4, thus E-LAPD using the PBL model was declared valid for use to improve science literacy in chemical equilibrium material.

This study was conducted because some students are still less able in learning multiplication or have not memorized multiplication from 1 to 10 and students who still think that multiplication operations are difficult to memorize, so that their multiplication calculation ability is still quite low. This study aims to determine the effectiveness of the jarimatika method with the Problem Based Learning (PBL) model on the multiplication calculation ability of grade 3 students of SD Negeri Pangarangan V. This study uses a quantitative descriptive research type with a descriptive model and a pre-experimental design approach. The sample in this study used 30 grade 3 students. Data collection techniques used in this study were observation, interviews, documentation and tests. Hypothesis testing requires data collection, in this study the researcher used a test (pretest-posttest). The implementation of the pretest and posttest can be seen from the average. The average pretest score obtained by students was 60.33 and the posttest score obtained by students was 80.00. Furthermore, the prerequisite test, namely the normality test, the researcher used the Shapiro Wilk technique. Based on the results of the normality test, the P-value at Sig. (2-tailed) in the pretest is 0.062 <0.05 and the P-value at Sig. (2-tailed) in the posttest is 0.065 <0.05. Next is the hypothesis test using the t-test (paired sample t-test), the results of the t-test calculation (paired sample t-test) using the help of SPSS 26 computer software show the P-value results at Sig. (2-tailed) of 0.000 which means <0.05 means H0 is rejected and Ha is accepted. Thus, the results of the hypothesis test state that the jarimatika method with the Problem Based Learning (PBL) model is effective for the multiplication calculation ability of grade 3 students at SDN Pangarangan V.

Oil palm is a key commodity supporting Indonesia’s economy through exports and employment. The industry’s success depends heavily on the selection of superior seedlings, which determine productivity, crop quality, and resistance to pests and diseases. Manual selection, however, often leads to subjectivity and inconsistency due to limited human resources and genetic variation. To address this, the study applies the Naïve Bayes algorithm for classifying oil palm seedlings based on seven variables: height, stem diameter, number of leaves, leaf color, disease resistance, root growth, and fruit yield. Using an explanatory quantitative method, the study follows seven stages: identifying problems, literature review, collecting 1,000 data entries from PT Intitama Berlian Perkebunan, data pre-processing, system modeling (UML), algorithm implementation, and evaluation using a confusion matrix and black box testing. Data was split into 80% training and 20% testing. The Naïve Bayes-based classification achieved 95% accuracy and perfect recall (1.00) for the superior seedling class. However, its performance on the minority class (non-superior seedlings) was weaker due to dataset imbalance. Black box testing verified all system functions worked correctly, enabling effective and efficient use by administrators. The study concludes that Naïve Bayes improves objectivity, efficiency, and accuracy in seedling selection. Nonetheless, attention is needed on data balancing and optimization to maintain consistent performance across classes. This system shows strong potential as a decision-support tool in plantations and promotes digital transformation in agricultural processes.
