Abstract

One of cognitive abilities of students that should be trained and developed in the 21st century learning is high-level thinking skills. As higher order thinking skills are emerging trend in education, assessment instruments based on high order thinking skills (HOTS) principles are required. This study aims to develop a high-level thinking ability instrument for Physics subject of senior high schools which is intended to measure HOTS of senior high school students for Thermodynamic Materials in City of Nganjuk in East Java. The study was conducted in three stages, including initial development, trials, and measurement. The initial development stage included compilation, review, and validation, including content validation by experts. There are two sets questions A and B, consisting 20 questions respectively, with anchor items as much as 5 items. The measurement results show that HOTS-oriented test kits of Thermodynamics have obtained empirical evidence are suitable with partial credit model. The difficulty level of the test battery is in the range of -2.0 to +2.0, with the most difficult aspects in the sequence are analyzing, evaluating, and creating. The reliability of HOTS-oriented tests has met the high categorical requirements, and based on the total information function of the tests, it is appropriately used to measure the HOTS of learners with capability -2.3 to +1.6. Based on students responses, the analysis ability is the highest skills followed by the ability to evaluate and create. HOTS-oriented tests developed can be used as the reference for the teachers to accommodate students higher order thinking skills.

Abstract

In general, in preparing the lesson, teachers determine some components namely learning objectives, procedures, and evaluation and assessment instruments. Several problems in Physics learning on Parabolic Motion indicate possible flaws from the three components in designing the lesson. Understanding by Design (UbD) is applied as one of the alternative strategies to improve the lesson quality by considering the learning objectives, procedures, and evaluation by reversing the design, namely proposing the objectives first, evaluations as the second, and lesson steps as the last step. This is a qualitative research intended to construct an alternative design of Physics learning on Parabolic Motion using UbD. The initial Physics learning design was reviewed and analyzed by experts and revised until the final design. Understanding by Design (UbD) could be used as an alternative design construction as it helps teachers to relate the three main components, namely learning objectives, evaluations, and steps so it eased the students understand the materials comprehensively and obtain maximum score. Despite the development of current materials needs more improvement, Understanding by Design (UbD) can applied for many materials.

Abstract

The coastal hydrogeological model of iron ore prospect area in Widarapayung coastal, Cilacap Regency, has been designed and performed based on the 2D-resistivity data. The background of this research is potentiality of iron sand in this area and its prospect to be mined. Mining activities in large-scale may lead into surface decreasing, triggering damage to the aquifer, abrasion, and saltwater intrusion in the coastal area. The acquisition of 2D-resistivity data has been performed on five trajectories including of WP-01 up to WP-05. Based on the modeling results, it can be concluded that the sub-surface rocks resistivity profile consists of WP-01 with the values of 1.93-114.00 Ωm; WP-02 with the values of 3.67-121.00 Ωm; WP-03 with the values of 3.86-78.40 Ωm; WP-04 with the values of 1.79-100.00 Ωm; and WP-05 with the values of 2.61-86.20 Ωm. After interpretation, it is found that the hydrogeological profile of sub-surface rocks consists of sand inserted with gravels (topsoil); sand containing iron ore granules inserted with silt (topsoil and shallow aquifer); clayey sand (semi-aquifer layer); sandy clay (semi-impermeable layer); and sand (deep aquifer which is intruded by salt water). Based on the analysis, the sand containing iron ore is part of the shallow aquifer, so the mining activities of iron sand is potential to damage and reduce aquifer function in storing and flowing the groundwater in the research area.

Abstract

This research reports the investigation of the performance of a thin layer based on silver nanorods using the dip-coating method. The synthesis was conducted by polyol method at an oil bath temperature of 140 °C. In the synthesis of silver nanorods, materials used were silver nitrate (AgNO3) as the main raw material, ethylene glycol (EG) as the solvent, and a small amount of sodium chloride (NaCl) as a mediated-agent (precursor). Polyvinyl alcohol (PVA) used as a capping agent and stabilizer in this process. Diameter and length of silver nanorods were 800 nm and 15 µm, respectively. Furthermore, the silver nanorods suspension was deposition onto a glass substrate with a variety of dipping cycles. The result showed the thickness of the thin layer is linear with a number of dipping cycles. Electrical and optical properties of thin layer show that sheet resistance about of 30 Ω sq-1 by transmittance above of 80%. The silver nanorods thin film can be used as a conductive and transparent electrode for various optoelectronic applications.
