Abstract

Tujuan penelitian ini adalah untuk mengetahui karakteristik TDS (Tes Diagnostdk Stoikiometri) yang dikembangkan dalam penelitian ini, mengidentifikasi, dan mendeskripsikan penyebab miskonsepsi stoikiometri yang terjadi serta menguji perbedaan firekuensi miskonsepsi stoikiometri pada siswa SMA berdasarkan perbedaan jenis kelamin, jenjang kelas, dan bahasa yang digunakan. Penelitian ini melibatkan 1096 siswa SMA kelas 2 dan kelas 3 di Kota Palangkaraya, Banjarmasin, dan Samarinda. Miskonsepsi stoikiometri yang dimiliki siswa diungkapkan menggunakan TDS bentuk pilihan ganda dan wawancara. Karakteristik TDS yang dikembangkan adalah: (1) stoikiometri disusun oleh tiga subkonsep dan terdiri dari 15 P3S, (2) panjang soal 48 butir, (3) waktu mengerjakan 90 menit, (4) tingkat kesesuaian P3S subkonsep rata-rata 1,30 - 1,90 (diterima), (5) tingkat KBP = 0,85 - 0,96 (sesuai), (6) tingkat KBS; harga Stress 0,1 -0,15 dan RSQ 0,92 - 0,93 (sesuai dengan model), (7) indeks TK = 0,31 - 0,68 (ideal), (8) indeks DB = 0,27 - 0,63 (ideal), dan (9) indeks koefisien a Cronbach 0,93 (baik). Hasil analisis konsentrasi mengidentifikasi 30 miskonsepsi stoikiometri yang dilakukan siswa, yaitu 13 miskonsepsi tentang persamaan reaksi, satu miskonsepsi tentang massa atom/molekul relatif, dan 16 miskonsepsi tentang moL Hasil uji c2 menunjukkan firekuensi miskonsepsi stoikiometri terbukti tidak tergantungpada perbedaan jenis kelamin, tetapi tergantung pada bahasa yang digunakan dan jejang kelas pada taraf 5%. Siswa yang menggunakan bahasa Indonesia dan siswa kelas 3 memiliki peluang lebih kecil melakukan miskonsepsi stoikiometri. Kata kunci: miskonsepsi, stoikiometri, tes diagostik stoikiometri, jenis kelamin, jenjang kelas, dan bahasa

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.
