Abstract

AbstrakTelah dilakukan pengukuran resistivitas dan dielektrisitas tanah perkebunan Apel di Malang. Pengukuran resistivitas dilakukan dengan metode Geolistrik dan dielektrisitas dengan menggunakan Ground Penetrating Radar (GPR). Metode Geolistrik dilakukan dengan konfigurasi dipole-dipole dengan teknik sounding –mapping pada tiga lintasan area perkebunan seluas 1800 m2 dan satu lintasan pada area lapangan di sebelah perkebunan. Sementara itu, metode GPR diterapkan pada dua pohon apel untuk mengidentifikasi sistem perakaran apel. Pengukuran resistivitas dilakukan di perkebunan Apel desa Bengkaras Pujon, Malang sedangkan GPR dilakukan di perkebunan Poncokusumo Malang. Dari hasil pengolahan data resistivitas dengan menggunakan software Res2dinv diperoleh hasil nilai resistivitas dari keempat lintasan adalah: lintasan pertama 4,83 – 22094 Wm, lintasan kedua 6,69 – 4947 Wm, lintasan ketiga 14,1 – 178 Wm dan lintasan keempat 4,50 – 20025 Wm. Dari data tersebut secara keseluruhan belum dapat dibedakan dengan jelas nilai resistivitas antara daerah perkebunan dengan bukan perkebunan di lingkungan penelitian. Sementara itu dari pengukuran GPR diperoleh jangkauan pengukuran mencapai kedalaman 2,18 meter dan jangkauan kedalaman akar apel 1.9 meter. Rentang nilai konstanta dielektrik yang diperoleh 0,1 – 8,8 F/m. Nilai konstanta dielektrik akar 4,9 F/m. Kata kunci: Resistivitas, dielektrisitas, tanah, perkebunan apel AbstractThe resistivity and dielectric properties of Apple’s soil plantation area in Malang have been measured.  Resistivity measurement was done using geo-electrical methods and dielectric properties was measured using ground penetrating radar (GPR).

Abstract

Abstract: The ways students solve problems become one of the main target of physics learning. Investigation about how students solve problems is explored in the context of metacognition skills. The steps of metacognition skills in physics problem solving include: planning, monitoring, evaluation, and controlling. This is a preliminary exploration study that aims to: 1.) mapping the metacognition skills that are used in physics problem solving of temperature and heat, 2.) exhibiting students’ self evaluation of his/her metacognition skills in problem solving, and 3.) identifying the relationship between students answer and their self evaluation. This is a descriptive qualitative study. The data were obtained by test and questionnaire. The physics problem solving test was given to 35 students of 11th grader. After doing test, they filled the 22 items of questionnaire adapted from Physics Metacognition Inventory (PMI). The result shows that none of the students solved all the problems optimally. The result of questionnaire showed that the average of metacognitive skills 64%, with the maximum and the minimum scores is 87% and 35% respectively. The correlation between the analyses of students’ answer and their self evaluation shows a negative value that indicates no relationship. Specifically, students pass the planning and controlling phase quite well, even though they tend to be poor in monitoring and evaluation. This findings must become a particular attention for the researchers and teachers in providing the learning strategy to habit the phases of metacognition skills in order to improve students’ metacognitive skills.

Abstract

The measurement of magnetic susceptibility, pH, element concentration of Fe and apples diameter has been conducted in orchard soil of Malang, East Java Indonesia. The measurement was performed in two orchards, namely Pujon and Poncokusumo with two different kind of apples in each orchard. This research aimed at exploring in detail linked between magnetic properties, the existence of magnetic mineral as magnetic property carrier in the soil, soil pH, as well as the size of apple diameter to evaluate the quality of apple production in the both areas. The results shows that the soil with lower susceptibility, it was expected that the magnetic mineral of magnetic property carrier to be smaller, low soil pH, meaning that the soil was more acidic which implied on a larger size of apple diameter for Rumbeauty type of apple. Meanwhile, when the soil had a higher susceptibility, and it is expected that the magnetic mineral is also high as well as having high pH, this growing media is appropriate to develop Manalagi type of apple. Based on the observed soil magnetic properties and pH from both observed orchards, it can be suggested that Manalagi apple is appropriate to be planted in Poncokusumo area, while Rumbeauty is appropriate to grow in Pujon area.

Abstract

This article presents a literature review on the effectiveness of the Hands-on Activity approach in enhancing students’ SPS. Data were obtained from 15 national and international research articles that met the inclusion criteria, namely discussing science learning based on direct activities, employing experimental methods, and providing data related to SPS development. Data analysis was conducted thematically by identifying patterns from instructional designs, SPS outcomes, and implementation contexts, with the aim of systematically reviewing the effectiveness of the Hands-on Activity approach in improving students' science process skills. The review findings consistently show that Hands-on Activity positively influences both basic SPS (such as observing, classifying, and measuring) and integrated skills (such as designing experiments and interpreting data). In addition to cognitive improvements, this approach also contributes to affective and psychomotor aspects, including learning motivation, scientific attitudes, and collaboration skills. Various forms of implementation—such as activity-based worksheets, simple laboratory tools, and digital technologies—highlight the flexibility of this method in diverse school contexts. Therefore, the Hands-on Activity approach is recommended as an effective, contextual, and adaptive teaching strategy for strengthening students’ SPS in science education
