Abstract

The implementation of PBL will help students develop the habits of thinking, attitude and behavior needed as professional educators who are competent, serving, and ethical. If done correctly, PBL can make an important contribution to improving teacher character. The purpose of this study is to develop PBL scenarios and determine the effect of PBL learning on increasing student competency as teacher candidates. PBL scenario development is done through logical review. Logical review aims to determine the validity of the case and steps to solve the case using the seven jump method. The results of this study are PBL scenarios for chemistry education research methods courses. The main obstacle in implementing PBL learning is that students' knowledge related to the concept of chemistry is very low, so students have difficulty identifying the problems raised in the case. Overall, students are able to formulate problems and research titles correctly even though the chemical substance under study is not yet understood. PBL learning is appropriate for subjects whose standard competencies demand student competencies in producing something.

Abstract

Utilization of coastal land in the community of Cemara Labat Village has been passed down from generation to generation. The people of Cemara Labat Village still maintain the tradition of coastal land management, such as planting certain types of mangroves, prohibiting cutting down mangrove forests and hunting animals which are regulated in unwritten customary law or local wisdom. Utilization of coastal area resources by humans from time to time continues to increase. The intensity of exploiting the potential of coastal areas resources often does not pay attention to the carrying capacity and principles of optimal and sustainable use of natural resources. Therefore, the mangrove forest ecosystem in Cemara Labat Village needs to be preserved both ecologically and biologically with an awareness approach to local wisdom. The data collection which used in this research was interview method, observation method, and survey. The results showed that Avicennia marina species had a very high dominance (80%) in the mangrove forest area of Cemara Labat Village, especially in the mangrove forest area, was bird species (Aves), while the level of community participation in mangrove forest conservation was moderate (76%). The strategy of developing community local wisdom on coastal land conservation in Cemara Labat village is in the Strengths-Opportunities or SO strategy, which is quadrant I which means Growth (6.40) or experiencing growth. Some alternative SO (strength opportunities) strategies include :a) Formulate regional policies on mangrove forest management, b) Promote the potential value of mangroves and their development opportunities, c) Improve the role and performance of stakeholders in mangrove forest management, d) Improve people's economy and empower coastal communities.

Abstract

Education in Indonesia aims to produce excellent students capable of contributing to the nation's progress. However, many schools still struggle to achieve an ideal level of learning, one of the contributing factors being the learning difficulties experienced by students. Chemistry is often perceived as a difficult subject due to its abstract and complex concepts. Determining reaction enthalpy changes in thermochemistry is one of the subtopics that students find challenging, leading to learning difficulties at the high school level. This issue is crucial to understand because chemistry concepts are interconnected, and difficulties in one area can affect the understanding of subsequent concepts. Hence, a study on students' difficulties in understanding the concept of determining reaction enthalpy changes is essential. This research was conducted on 125 Grade XI-MIPA students from two high schools in Palangka Raya. Data on students’ difficulties were collected using a diagnostic essay test instrument on the ability to determine reaction enthalpy changes (TKPPER), consisting of four questions. The aim of this research was to describe the difficulties experienced by Grade XI-MIPA students in the 2022/2023 academic year in understanding the concept of determining reaction enthalpy changes using diagnostic essay tests. The results showed that students experienced difficulties in understanding the concept of determining reaction enthalpy changes, with an average difficulty percentage of 37.44%. Several conceptual indicators focused on in the study exhibited varying levels of difficulty: Determining reaction enthalpy changes based on Hess's Law (65.67%), with students facing the following difficulties: (a) Assuming it is sufficient to sum the enthalpy change values (∆H) of three reactions provided in the question without considering the thermochemical equations of these reactions. (b) Believing that the value and sign of ∆H remain the same even when the thermochemical equation is reversed or the roles of reactants and products are switched. Determining reaction enthalpy changes based on bond energy (43.90%), with students experiencing the following issues: (a) Assuming that some compounds involved in the reactants and products are treated as single compounds in the chemical reaction. (b) Simply summing the bond energy values of each compound in the products and reactants without considering the number of bonds in each compound. Determining reaction enthalpy changes based on standard enthalpy change data (20.38%), with students facing the following challenges: (a) Assuming that the reactants in a chemical reaction are the products and vice versa. (b) Believing that it is sufficient to sum the bond energy values of each compound involved without accounting for the number of compounds (stoichiometric coefficients) in the reaction. Determining reaction enthalpy changes based on calorimeter experiment data (19.82%), where students struggled with identifying the values of the components in the formula, specifically determining the mass of water (m), specific heat capacity of water (c), and temperature change (∆T).
