Abstract

Observasi awal terhadap proses pembelajaran IPAFisika di salah satu SMP Kabupaten Pekalongan, menunjukkan pembelajaranyang hanya dilakukan secara mekanistis, kurang memperhatikan kemampuan berpikir dan siswa cenderung pasif sehingga hasilbelajar masih rendah. Penelitian ini menerapkan metode pembelajaran (TPS) dengan maksud memberikesempatan kepada siswa untuk berpikir dan merespon, membantu satu sama lain, sehingga setiap siswa dapatmengembangkan kemampuan berpikir, pemecahan masalah, dan ketrampilan sosialnya. Penelitian ini bertujuan untukmeningkatkan aktivitas dan hasil belajar siswa melalui penerapan metode pembelajaran TPS dengan desain PTK dalam tigasiklus. Data diambil dengan lembar observasi dan LKS untuk mengetahui aktivitas siswa dan tes hasil belajar untuk mengetahuipemahaman materi. Hasil penelitian menunjukkan adanya peningkatan nilai rata-rata kelas tiap siklus, persentase ketuntasanklasikal pada aktivitas dan hasil belajar kognitif siswa. Siswa merasa senang dan menikmati pembelajaran bermetode TPS.Disimpulkan bahwa penerapan metode TPS dalam pembelajaran IPA Fisika mampu meningkatkan aktivitas dan hasil belajarsiswa. The preliminary observation on the physics learning process in one of the secondary schools in Pekalongan District shows that thelearning process is just mechanics instruction and give no more attention on the thinking ability, so that the students to be passiveand students learning achievement are low. In this research, we applied Think-Pair-Share method. This method is selected to giveopprtunity for students to think, to respond, and to cooperate, so that each student can develop their capabilities in thinking, solvingthe problems as well as improve their social skills. The goal of this research is to improve the students activities in learning processwhich have a good impact on the students achievements by applying TPS learning method and in three cycles of action researchdesign. Data were gathered from observations and students worksheets to explore their activities during learning process and fromcognitive test results to know their understanding of sounds concepts. The analysis results show that there is a significantimprovement of students activities and their achievements in every cycle. The students feel happy and enjoy the class. It can beconcluded that the implementation ofTPS learning method in learning phyics increase students activities and their achievements.Keywords: student’s achievements; sounds;Think-Pair-Share

Abstract

Beberapa faktor yang menyebabkan siswa sulit memahami materi ajar adalah sulit konsentrasi, mudah lupa, merasa bosan, tidak kreatif, suasana belajar tidak menyenangkan, dan merasa tegang. Penelitian ini bertujuan untuk mengembangkan CD pembelajaran lagu anak untuk menumbuhkan pemahaman sains siswa sekolah dasar. Jenis penelitian ini merupakan penelitian pengembangan. Instrumen yang digunakan dalam penelitian ini adalah angket uji ahli, tes rumpang dan tes uraian. Hasil penelitian yang telah dilakukan adalah sebagai berikut: 1) Berdasarkan analisis kualitatif diperoleh bahwa CD pembelajaran lagu anak termasuk kategori sangat layak untuk dijadikan media pembelajaran sains siswa sekolah dasar. 2) Berdasarkan hasil uji t dan uji gain ternormalisasi diperoleh bahwa terjadi peningkatan pemahaman sains siswa sekolah dasar dengan kategori tinggi (g= 0,74).Some factors influencing the students’ understanding about a teaching material are difficult to concentrate, easy to forget, feel bored, lack of creativity, inconducive learning process, and feeling of stress. The goal of the research is to develop a learning CD containing children song in order to grow science understanding of elementary school student. This R & D research applied instruments of expert questionnaire, close test, and essay test. The result of the research are 1) based on the qualitative analysis it can be conclude that the developed learning CD is feasible to be used as a learning media for elementary school student; 2) the t test and normalized gain test analysis show that there is a significant improvement of students’ science understanding in high category (g score = 0.74).

Abstract

A copper phthalocyanine (CuPc) thin film based gas sensor with FET structure and channel length 100 μm has been prepared by VE method and lithography technique to detect NH3, motor cycle exhaust gases and CO. CuPc material layer was deposited on SiO2 by the vacuum evaporator (VE) method at room temperature and pressure of 8 x10-4 Pa. The stages of manufacturing gas sensor were Si/SiO2 substrate blenching with ethanol in an ultrasonic cleaner, source, and drain electrodes deposition on the substrate by using a vacuum evaporator, thin film deposition between the source/drain and gate deposition. The sensor response times to NH3, motorcycle exhaust gases and CO were 75 s, 135 s, and 150, respectively. The recovery times were 90 s, 150 s and 225, respectively. It is concluded that the CuPc thin film-based gas sensor with FET structure is the best sensor to detect the NH3 gas.Sensor gas berbasis film tipis copper phthalocyanine (CuPc) berstruktur FET dengan panjang channel 100 μm telah dibuatdengan metode VE dan teknik lithography untuk mendeteksi NH3 gas buang kendaraan bermotor dan CO. Lapisan bahan CuPc dideposisikan pada permukaan silikon dioksida (SiO2) dengan metode vacuum evaporator (VE) pada temperatur ruang dengan tekanan 8 x10-4 Pa. Tahapan pembuatan sensor gas adalah pencucian substrat Si/SiO2 dengan etanol dalam ultrasonic cleaner, deposisi elektroda source dan drain di atas substrat dengan metode vacuum evaporator, deposisi film tipis diantara source/drain dan deposisi gate. Waktu tanggap sensor terhadap NH3, gas buang kendaraan bermotor dan CO berturut-turut adalah 75 s, 135 s,dan 150 s. Waktu pemulihan berturut-turut adalah 90 s, 150 s,dan 225 s. Disimpulkan bahwa sensor gas berstruktur FET berbasis film tipis CuPc merupakan sensor paling baik untuk mendeteksi adanya gas NH3.

Abstract

Human activities that produce carbon dioxide emissions and are called carbon footprints or carbon footprints have a big role in global warming. As part of its contribution to climate change mitigation efforts and environmental preservation, Faculty of Mathematics and Natural Science Universitas Negeri Semarang (FMIPA UNNES) has been actively developing conservation policies. The programs developed as an effort to mitigate climate change have been running for a long time. However, so far it is not certain how much CO2 emissions are produced and minimized by FMIPA UNNES. The purpose of this study was to analyze the amount of CO2 emissions produced in the FMIPA environment, to map the carbon footprint (CO2) produced from activities on the Unnes campus, to identify what factors influence CO2 emissions resulting from activities in FMIPA. The research was conducted from May to October 2020. The data obtained were obtained from primary data and secondary data. Primary data were obtained through field surveys, while secondary data were obtained from existing data. The carbon footprint that will be taken is obtained from electronic measurements, waste and transportation. The data instrument was converted into carbon footprint units (grams CO2-ek) using a carbon footprint calculator (Ver 2) developed by IESR. The results showed that the carbon footprint generated from campus activities at FMIPA in 2020 before the Covid-19 pandemic outbreak was 10,670.25 ton CO2-eq / month. This carbon footprint decreased during the pandemic to 4,312.27 ton CO2-eq / month. This total carbon footprint consists of scope one in the form of transportation activities by operational vehicles and use of LPG, scope two of electricity spending activities, scope three in the form of transportation activities by lecturers, staff, and students, use of paper, and waste disposal.
