Abstract

Estimating rainfall accurately is crucial for both the community and various institutions involved in managing water resources and preventing disasters. The XGBoost model has demonstrated its effectiveness in predicting rainfall, but it still requires fine-tuning of hyperparameters to enhance its performance. This study seeks to determine the optimal learning rate for rainfall prediction while keeping the max_depth and n_estimator parameters fixed. The hyperparameter optimization process was carried out using a two-step approach: an initial coarse search using RandomizedSearchCV followed by a more detailed fine-tuning using GridSearchCV. The model's foundation relied on historical rainfall data gathered over three months from the Automated Weather Observed System (AWOS) at the Pontianak Meteorological Station, recorded on an hourly basis. To assess the model's performance, several metrics were employed, including accuracy, precision, recall, F1 score, and ROC-AUC. The model demonstrated promising results, with accuracy, precision, recall, and F1 score all reaching 95%, indicating its ability to effectively predict rainfall. However, the ROC-AUC score was somewhat lower at 62%. After conducting the hyperparameter search, the optimal learning rate determined for the model, utilizing the 2040 dataset, was found to be 0.204.

Abstract

Research and practice in educational settings should consider exploring the rich diversity of emotions experienced by students outside classroom settings, including nature clubs, as a conservation education program. This study aimed to conduct an exploratory case study to explore students' academic emotions during conservation education programs. The case study was carried out for four weeks to determine what can be learned from a single case about the students’ emotional aspects of the conservation education program in the Nature Club. Data collection is conducted through observation, interview, and collection of documents at the end of every activity. The data consisted of field notes and videotapes from observation, interview transcripts, and student emotions diary (SED). The research participant was 21 elementary students aged 9 to 11 who joined the Nature Club conducted by the Little Fire Pace (LFP) Community as one of their conservation education programs. The result shows that conservation content which is also part of science, can be learned and stimulate the emergence of students' academic emotions, both positive and negative. The dominant emotion in nature club activities is the happy emotion, and the slightest emotion arising from this activity is disgust. Then the results of student interest in all activities were more remarkable than boredom. Finally, suggestions are made on implications for teacher or pre-service teacher education for conservation or science education.

Abstract

The inquiry learning model is a model that facilitates the construction of students' scientific knowledge which can also improve students' argumentation skills. According to several research results, inquiry-based learning has proven to be effective in improving scientific argumentation skills because in the learning process students are directed in investigative activities to find scientific evidence as a basis for scientific argumentation. By considering the student learning process, the aim of this research is to describe whether the use of three types of inquiry learning models can teach fluid material and influence the student learning process, one of which is students' argumentation abilities. This research method uses mixed method triangulation. The instruments used were interview questionnaires and argumentation tests. The data obtained was then analyzed using simple statistical tests and N-gain scores. Interview data was analyzed to find out clarification of students' answers. The research results of the inquiry learning model were successful in developing argumentation skills, namely the n-gain score resulted in the use of the structured inquiry learning model gaining 0.88, the guided inquiry learning model 0.84 and the open inquiry learning model 0.74.

Abstract

Learning using the problem-based learning (PBL) enables students to solve problems as well as improve their science knowledge and skills. This study aims to investigate the effect of the use of PBL on critical thinking skills of high school students in biotechnology. Various levels of students’ self-confidence are used as a moderating variable for PBL in producing the effect. A total of 64 students of SMAN 8 Batanghari Jambi were involved in this study. Some 32 students were allocated each to the experimental class which was learning using PBL and the control class which was learning using the expository learning. Data were collected using a pre-validated self-confidence questionnaires and tests of critical thinking skills. The factorial type of quasi-experimental with pretest posttest nonequivalent control group design was used in this study. The collected data were analyzed using a two-way ANOVA test. The results showed that PBL-students had a higher average score of critical thinking skills (85.87) than their counterpart (78.80). The data also showed that the students with better self-confidence also have a higher average score of critical thinking skills (85.32) than those with lower self-confidence (79.34). The results of the two-way ANOVA test showed that there was an effect of the use of PBL and the students' self-confidence on students' critical thinking skills. Even though it is very weak, the interaction between the learning model and the self-confidence was seemingly existed in affecting the students' critical thinking skills. It can be concluded that the appropriate learning model and appropriate self-confidence can affect student learning critical thinking skills

Abstract

Quality feed in aquaculture is very important to increase the growth and health of fish. Low feed efficiency can be overcome by feed supplementation using catalytic enzymes. One of the enzymes that can stimulate digestion is protease in red ginger plants. The protease enzyme in red ginger plants plays a role in breaking peptide bonds in place of carboxyl groups so that peptides are formed from complex compounds into simpler compounds. This study aims to determine the profile of amino acids and proximate in feed given red ginger enzymes. This research uses descriptive method. The feed sample used was commercial feed with 4 treatments namely Control (without red ginger enzyme), treatment A (1%), treatment B (3%), and treatment C (5%). The analyzes carried out included red ginger enzyme extraction, protease enzyme purification, proximate and amino acid analysis of each type of feed. The results showed that the results of the SDS-Page analysis on the red ginger protease sample contained at 67.1 kDa. The results of the proximate analysis showed the highest value in feed containing 3% red ginger protease (B) with a percentage of 42.69%. The resulting amino acid content consists of 8 non-essential amino acids namely, L-serine, L-glutamic acid, L-alanine, L-arginine, glycine, L-aspartic acid, L-tyrosine and L-proline. While the essential amino acids consist of 7 types of amino acids namely, L-Phenylalani, L-Isoleucine, L-Valine, L-Lysine, L-Leucine, L-Threonine and L-Histidine. The best type of feed is feed B, which is feed with the addition of 3% red ginger protease.
