Abstract

The ability to reason scientifically (scientific reasoning) is needed in understanding science, including chemistry. The patterns of scientific reasoning enable students to analyze facts or information logically and systematically. Students with good scientific reasoning skills are expected to be able to construct concepts better. This study aims to describe the scientific reasoning ability of Mechanical Engineering Education students in Engineering Chemistry courses. Research subjects numbered 65 people. Students' scientific reasoning abilities are measured by the Classroom Test of Scientific Reasoning (CTSR). Based on this CTSR test score, the level of student development can be categorized into four levels of development, namely the level of concrete, low formal, upper formal and post formal. The results showed that as many as 89% of students were still at the level of concrete reasoning and only 11% had reached the level of reasoning low formal. This shows the level of scientific reasoning ability of students is still low and there is a delay in the development of reasoning ability. The lowest type of reasoning is the probability reasoning pattern and the conservation reasoning pattern is the reasoning most mastered by students.

Abstract

Kebakaran hutan dan lahan gambut terus meluas ke beberapa desa sekitar perkebunan kelapa sawit di eks PLG 1 juta hektar sejak Agustus 2015. Kebakaran terjadi di beberapa kabupaten termasuk Kabupaten Kapuas, Pulang Pisau, Palangka Raya dan Kabupaten Kotawiaringin Barat–Timur. Pada kebakaran tahun 2015, diupayakan pencegahan dan penanggulangan kebakaran yang terus meluas dari areal perkebunan kelapa sawit dan wilayah gambut kering yang memberi dampak bagi warga masyarakat di Kecamatan Mantangai, Kapuas Murung, Desa Tumbang Nusa, Kota Palangka Raya dan Kabupaten Barito Selatan. Desa Kalumpang merupakan salah satu desa rawan kebakaran hutan dan lahan gambut yang ada di wilayah Kabupaten Kapuas. Tujuan umum kegiatan ini adalah memperkuat partisipasi warga masyarakat dalam melakukan pencegahan, penanggulangan dan pemulihan ekosistem gambut paska kebakaran hutan dan lahan gambut serta untuk mengantisipasi kebakaran di tahun berikutnya, dan juga bertujuan memberikan pemahaman tentang pengelolaan sumberdaya hutan dan lahan gambut yang berkelanjutan berbasis kearifan local. Metode kegiatan yang digunakan yaitu: sosialisasi pengelolaan sumberdaya hutan dan lahan gambut yang berkelanjutan berbasis kearifan lokal dan pengakuan hak kelola masyarakat, pendampingan kegiatan pengelolaan sumberdaya hutan dan lahan gambut yang berkelanjutan serta evaluasi

Abstract

This study uses a systematic review method. The research was conducted to describe and summarize the results of analyses related to students' difficulties in understanding the concept of reaction rates. The sample in this study consists of three theses on difficulties in understanding the concept of reaction rates. The data in this research are the students' difficulties based on the patterns of their answers and the instruments used in each thesis. The analysis of the instruments includes Basic Competencies (KD) and Operational Verbs (KKO) from the three theses, while the students' difficulties are analyzed by comparing the patterns of their answers. The results of the study on students' difficulties in understanding the concept of reaction rates are as follows: (1) students define that the reaction rate is the increase in the concentration of one of the reactants per unit time, (2) students consider the reaction rate to be, (3) students regard the index value as the coefficient used to divide the rate expression and use the index to balance the reaction, (4) in determining the reaction order based on experimental data tables, students consider that the reaction order is the quotient of the rate value divided by the concentration of the reactant, (5) students believe that the total reaction order is obtained by multiplying the concentration exponents or reaction orders, (6) students have difficulties with the chemical calculation concept in determining the reaction order based on experimental data tables, assuming that the reaction order is the quotient of the rate value divided by the concentration of the reactant, (7) students consider that the reaction order value is the concentration value in a reaction rate equation, and (8) students are not meticulous in interpreting the known data into their calculation formulas and believe that the reaction rate value can be obtained from the coefficient of the product.

Abstract

This study investigates the dynamics of water level (TMA), electrical current, power, and battery voltage in a data loggerbased monitoring system designed for peatlands. Data collected from October 30 to December 4, 2024, highlight significant fluctuations influenced by environmental factors, load surges, and voltage disruptions. Scenario simulations, including changes in rainfall, sudden load increases, and voltage system disturbances, were performed to evaluate the system's operational efficiency and stability. The findings indicate that TMA is highly influenced by hydrological conditions, where a 50% reduction in rainfall significantly decreases TMA, impacting the stability of current and power. A 50% load surge drives the current and power close to the system's maximum capacity, while voltage disruptions lead to a 20% increase in current and a 20% reduction in power, revealing system imbalances. Energy efficiency remains stable under normal conditions (0.0022) but drops significantly during disruptions. The study underscores the need for integrating protective technologies, such as Automatic Voltage Regulators (AVR), Overcurrent Protection, and balanced load management, to mitigate risks and maintain system stability. Additionally, improved water management in peatlands contributes to stabilizing TMA and reducing environmental impacts on electrical parameters. This research highlights the importance of a holistic approach, combining technology, hydrological management, and data-driven simulations, for sustainable operations. The findings offer practical recommendations for system enhancement, risk mitigation, and the development of future energy monitoring tools. Opportunities for renewable energy integration are also explored to ensure long-term operational efficiency and environmental sustainability.
