Abstract

Physics practicum is an important activity in basic physics courses that involve contextual physics concepts, such as cases in coastal areas which can demand students’ problem-solving skills. Covid-19 has caused basic physics practicum activities to become difficult to carry out in a laboratory scale, thus alternative solution is necessary to perform practical activities in the Covid-19 situation, namely by utilizing Augmented Reality (AR) technology. AR can help visualize physics concepts and practicum activity procedures relevant to practicum activities. This study aimed to develop an AR-assisted practicum guidebook product oriented toward a problem-solving method by presenting several cases of natural potential in local coastal areas. This study used an R&D method with a 4D model. However, this study was limited to the development stage. Data were collected with validation sheets and student response questionnaire sheets. These data were then analyzed with descriptive qualitative data analysis technique. Based on the data analysis results, many students had difficulties in carrying out physics practicum activities during the Covid-19 pandemic. This occurred due to the unaccessible practicum video procedures in the guidebook during the offline condition. Furthermore, the practicum procedure guidebook was only in narrative text, unable to stimulate high-level thinking skills by presenting coastal area cases. Students must be introduced deeper to the potential of coastal areas and their relation to physics concepts.

Abstract

Cukuh Raya Beach coastal water is potentially polluted by organic materials from shrimp ponds. The purpose of this study was to determine the content of organic materials (ammonia [NH3], nitrate [NO3], phosphate [PO4], and fatty oil) discharged into the coastal waters and to examine the role of eco-enzymes in reducing the organic material levels. Two points of sampling were selected, i.e., 10 and 100 m from the pipeline outfall discharge of shrimp ponds. An experiment was carried out to compare the level of organic content before and after the eco-enzyme solutions were given. Sampling and technique analysis of seawater were done following the Indonesian National Standards. The data were analysed using the Indonesian quality standards for marine biota and the pollution index. The results showed that seawater samples from the coast contained organic waste, with the highest levels at 10 m from the outfall. The level of organic content decreased after the addition of eco-enzyme solutions. The conclusion is that the organic materials (ammonia, nitrate, phosphate, and fatty oil) were found in water samples in the waters of Cukuh Raya Beach and were moderately polluted by ammonia (NH3). The addition of an eco-enzyme solution can reduce the concentration of organic materials.

Abstract

The purpose of this study was to investigate the effect of static fluid pressure learning with Predict, Observe, Explain (POE)-oriented student worksheets on the eighth-grade students' science process skills. This research employed a non-equivalent control group design. A total of 166 students from five classes in class VIII at State Junior High School 03 in Bengkulu City represented the research population. Students in class VIII-1 (control group) and class VIII-2 (experimental group), for a total of 58 students, were selected as subjects using non-probability sampling and the convenience sampling method. By applying non-parametric inferential statistics, particularly the Mann-Whitney U test, the hypothesis was examined. The results confirm that the use of POE-oriented worksheets in learning the concept of pressure in static fluids has a statistically positive effect at the significance level (0.05) with a p-value (0.003) on science process skills, and the effect size (r=0.39) is in the medium category. The availability of worksheets that rely on scaffolding strategies such as POE may enable students in secondary schools to construct their own knowledge during the learning process.The provision of worksheets that employ scaffolding techniques, such as the Predict-Observe-Explain (POE) approach, has the potential to facilitate the development of students' knowledge construction and science process abilities in secondary school settings.

Abstract

Abrasi merupakan proses alami berupa pengikisan tanah di daerah pantai yang disebabkan oleh gelombang dan arus laut yang merusak, kadang disebut juga erosi pantai. Kerusakan pantai tersebut salah satunya dapat disebabkan oleh terganggunya keseimbangan alam wilayah pesisir. Keausan umumnya disebabkan oleh fenomena alam, tetapi banyak tindakan manusia juga berkontribusi terhadap keausan pantai. Secara sederhana, abrasi adalah pengikisan wilayah pesisir oleh gelombang dan arus yang merusak. Adapun akibat yang ditimbulkan abrasi yaitu penyusutan garis atau area pantai, kerusakan hutan mangrove, permasalahan sampah dan pergeseran mata pencaharian masyarakat sekitar. Dibalik akibat yang ditimbul, ada beberapa hal yang dapat dilakukan dalam mitigasi (upaya) pencegahan dan pengurangan resiko abrasi. Mitigasi terbagi menjadi mitigasi struktural dan mitigasi non-struktural, untuk mitigasi struktural contohnya yaitu penanaman hutan mangrove dan membangun pemecah gelombang dan mitigasi non-struktural menekankan pada aspek perencanaan guna lahan, insentif pemerintah, pelatihan dan pendidikan bagi masyarakat, kesadaran publik. Upaya tersebut tentunya dapat dilakukan oleh pemerintah dan masyarakat sekitar. Termasuk warga sekolah yang berada di pesisir pantai. Guru dapat memberikan pembelajaran mitigasi bencana abrasi dengn mengintegrasikannya kedalam materi Gelombang fisika kelas XI.

Abstract

Physics is a science that involves high curiosity about natural phenomena which are then solved using scientific methods. The learning program is designed to improve scientific reasoning skills, one of which is by using the Phenomena Based-Interactive Conceptual Instruction (PB-ICI) learning model. This research aims to implement the Phenomena Based-Interactive Conceptual Instruction (PB-ICI) learning model to improve students' scientific reasoning through IPBA courses. This research uses quasi-experiment, including pre-experimental, experimental and experimental data analysis stages. Based on the results of data analysis, it is known that student reasoning is spread across the categories of inductive-deductive reasoning at 30%), reasoning with evidence at 33%, reasoning with data at 33%, no reasoning at 3%, and undefined at 0%. The effectiveness of IPBA learning in instilling scientific reasoning is in the medium category with a distribution percentage of 63%. Based on these results, it can be interpreted that students have been able to organize various knowledge in the form of concepts, theories, laws, principles as well as data and facts to explain earth and space phenomena comprehensively. It can be concluded that IPBA learning using the PB-ICI model can train reasoning skills. After learning activities, 63% of the total students had reasoning in the categories of inductive-deductive reasoning and reasoning with evidence.
