Abstract

Module development is very important in chemistry learning. The lack of modules as teaching materials is an obstacle in learning chemistry, especially the reaction rate material. Therefore this study aims to develop and validate the feasibility of the chemistry module on the reaction rate material through a scientific approach, as well as to assess how students and teachers respond to the product being developed. The research and development (R&D) method is the method used and ADDIE is the development model applied as the methodology. The sample in this study was 15 students. The sampling technique is saturated samples. Modules are validated by material and media validators and then validated by teachers and asked for responses from students. Data is processed using SPPS Reaction rate as the subject of this research. The developed module is very feasible to be applied in chemistry learning on reaction rate material, according to the results of the data analyzed. The material validator gave an average score of 91.77% (very feasible), the media validator 90.48% (very feasible) and the teacher's response was 99.07% (very good) and the students' response to the developed module was 97.50% (Very good).Keywords: Chemistry; Module; Reaction rate; Scientific approach

Abstract

Zeolit alam dapat digunakan sebagai bahan pengisi komposit polietilen sehingga komposit akan memiliki kekerasan yang tinggi dan dapat digunakan untuk kemasan bahan plastik yang kaku dan keras. Zeolit alam yang digunakan dalam percobaan pembuatan komposit ini berasal dari Sentani kabupaten Jayapura, Papua. Hasil karakterisasi mineral dan kristalinitas zeolit tersebut menunjukkan sebagian besar tersusun oleh mineral mordenit (CaNa2K2)Al2Si10O24 dengan derajat kristalinitas 53,14%. Percobaan pembuatan bahan komposit dilakukan dengan cara mencampurkan polietilen dengan bahan pengisi zeolit alam yang dipanaskan pada suhu 188°C selama 8 menit dengan variasi berat pengisi 1 – 65% dari berat polietilennya dan ukuran butir zeolit -150 + 200 mesh. Komposit hasil penelitian mempunyai kekuatan saat putus ≥ 16,887 MPa, kekuatan tarik ≥ 26,367 MPa dan pemuluran putus ≤ 1,331 MPa. Kekerasan komposit semakin meningkat dengan bertambahnya zeolit. Komposit ini tahan terhadap cuaca selama 16 minggu dan baik dimanfaatkan untuk pembuatan pipa dan/atau exsterior blind.

Abstract

The background introduces Tambrauw Regency's formation and the need for a governmental center, specifically focusing on Fef District as per Indonesian law. The introduction also touches upon the administrative, strategic, and technical aspects that must be considered in selecting a capital. This section discusses theories related to location, spatial order, and urban functions, with references to prominent theories like those of Tarigan (2006) and Yunus (2005). It provides a foundational understanding of urban centers' roles and the criteria for selecting administrative capitals. The research employs documentation study methods, analyzing secondary data from relevant institutions, statistics, and legislation. The analytical approaches include Scalogram Analysis, SWOT Analysis, and Christaller's Central Place Theory, providing a multi-faceted examination of Fef District’s suitability. The Scalogram Analysis indicates that Fef ranks sixth in terms of infrastructure, suggesting that other districts may be better prepared as governmental centers. However, Christaller's theory highlights Fef's strategic location as a justification for its selection as the capital. The SWOT analysis outlines strengths, weaknesses, opportunities, and threats, emphasizing the need for accelerated development in Fef to support its role. While Fef's current infrastructure may not be fully adequate, its strategic location supports its potential as the governmental center. The paper suggests that careful planning and development are necessary to transform Fef into a functional capital for Tambrauw Regency.
