Abstract

Biodiversity is one of local wisdom that should be kept and maintained. Several local governments have different ways of managing and maintaining their existence, including in Krimun village-Losarang, Indramayu District, West Java Province. This study is aimed at finding the information about Suku Dayak people in Losarang (which is not same as Dayak in Borneo Island), how they manage and utilize biodiversity in their surroundings, and how it relates to the local wisdom. This is a qualitative research with instruments consists of interview sheets, field notes, and audio-visual documentation. The subject of this research is the Suku Losarang Dayak people whom are selected through incidental sampling techniques. The study of Ethnobotany includes utilization of 56 species plants as food, three species as boards, nine species for medicine, two species for aesthetics, and nine species for rituals. Ethnoecology here means the conservation of community of the Suku Dayak Losarang people toward surrounding ecosystems that are conserved for the needs of farming, shelter, and ritual. Concerning for ethnozoology, none of the species was used because they have a principle "ngaji rasa". This principle means that they would not be allowed to consume or to make use of the living creatures.

Abstract

ABSTRACTThe study aims to determine the effect of Problem Based Instruction learning model on the concept of pollution to the problem solving ability of high school students. This research is a kind of quantitative research. Population in this research is student of class X SMA Negeri 1 Lohbener. Cluster random sampling technique was taken by two classes and obtained by X-MIPA 4 students as experiment class by using Problem Based Instruction and X-MIPA 2 as control class by using discussion method. The instrument used is in the form of five essay questions in accordance with the problem-solving indicator that is restricted to the C3-C5 cognitive domain that has been tested for its validity and reliability. After a different treatment, each posttest is given. Based on the result of the research, the average value of experimental class is 72.25 and the control class average 58.95. Then by using t test, obtained tcount = 4.092> ttabel = 1.680. Based on hypothesis testing can be stated that Ho is rejected. So that the problem-based instruction model influences student's problem solving abilities. Keywords: pollution, problem based instruction, and problem solving ability.  ABSTRAKPenelitian ini bertujuan untuk mengetahui pengaruh penggunaan model pembelajaran Problem Based Instruction pada konsep pencemaran terhadap kemampuan pemecahan masalah siswa SMA. Bentuk penelitian eksperimen berdesain postest only control group design. Populasi dalam penelitian ini adalah siswa kelas X SMA Negeri 1 Lohbener. Teknik pengambilan sampel secara cluster random sampling diambil dua kelas dan didapatkan siswa kelas X–MIPA 4 sebagai kelas eksperimen dengan menggunakan model pembelajaran Problem Based Instruction. Instrumen yang digunakan adalah berupa lima soal essai sesuai dengan indikator pemecahan masalah yang dibatasi pada ranah kognitif C3-C5 yang telah diuji validitas dan reabilitasnya. Setelah dilakukan perlakuan yang berbeda, masing-masing diberikan posttes. Berdasarkan hasil penelitian, diperoleh nilai rata-rata kelas eksperimen 72,25 dan rata-rata kelas kontrol 58,95. Kemudian dengan menggunakan uji t, diperoleh thitung=4,092 > ttabel=1,680, maka H0diterima. Disimpulkan bahwa model pembelajaran Problem Based Instruction berpengaruh terhadap kemampuan pemecahan masalah siswa. Kata Kunci: pencemaran, problem based instruction, dan kemampuan pemecahan masalah.

Abstract

Less varied learning method result in low scientific literacy of students. This study aims to determine whether the application of lesson study in learning can improve students' scientific literacy skills in the Respiratory System material. This research is action research carried out at SMA Negeri 1 Lohbener. The subjects in this study were students of class XI IPA 1 with a total sample of 22 people. The instrument used in this study was HOTs-based literacy question sheets which were given in each cycle to measure students' scientific literacy improvement. The results of data processing obtained an average score of scientific literacy skills in cycle I of 53.0 with a percentage of 53% and in the very low category, the average score in cycle II of 57.0 with a percentage of 57% and in the low category, and the average score in cycle III of 67.0 with a percentage of 67% and in the moderate category. The main factor causing an increase in students' scientific literacy skills only reaching the moderate category was students who were not used to answering HOTs-based literacy questions and were used to answering LOTs-type questions, so they experienced difficulties in doing the formative tests given. Even so, the application of lesson study in learning material on the respiratory system is proven to be able to improve students' scientific literacy skills at each level. Based on the results of observations of teachers and students during the implementation of cycle actions, it appears that the implementation of actions has reached the predetermined performance indicators
