This study was aimed at clarifying the learning activities for explicit Nature of Science (NOS) which provide through context based STS (Science, Technology, Society) learning approach. The study followed the 4-D procedure but in this article only was presented up to the third step. These steps included define, design, and develop. The data were gathered through expert judgment by chemistry educator for product revision. The views of the chemistry teacher were explored through a closed-questionnaire that was analyzed by percentage. One of learning activity plan have arranged. The learning activity with context based STS approach consists of 5 stages including identification of social issues/history, identification of potential solution, need for knowledge, decision-making, and socialization and completion decision stage. Chemistry teachers’ view toward the feasibility of learning activity plan was good. The learning activity was developed with topic a history of the Father of Modern Chemistry for grade 10th. The findings show thatt his learning activity is able to help teacher for teaching NOS in classroom and foster students’ NOS through a historical story.

Abstract The aim of this study was to determine the effect of the implementation of e-learning to the students’ independence and interests in Science insight and Study Course. The used method was experimental post-test only control group design by questionnaire sheets. The subjects were Chemistry Education students year 2015. The results of the hypothesis-test showed that there are no significant differences of independence and interest in both of groups. However, the results of descriptive data analysis showed that the average students’ independence and interest in the experimental was higher than the control group. The experimental group mean of 3.67 (good), while the control group average of 3.48 which are at the same category. Average students’ interest in the experimental group of 4.21 (very good), while the average in the control group at 4.08 (good). In addition, based on the questionnaire of students’ responses toward e-learning obtained mean of 4.51 (very good).

Metode penelitian yang digunakan adalah eksperimen dengan post-test only control group design dan instrumen lembar angket. Subyek dalam penelitian ini adalah mahasiswa Pendidikan Kimia angkatan 2015. Hasil uji hipotesis menunjukkan tidak ada perbedaan yang signifikan antara kemandirian dan minat belajar pada kedua kelompok. Namun, hasil analisis data deskriptif menunjukkan bahwa rerata kemandirian dan minat belajar mahasiswa pada kelompok eksperimen lebih tinggi dibandingkan kelompok kontrol. Rerata kelompok eksperimen sebesar 3,67 (baik), sedangkan rerata kelompok kontrol sebesar 3,48 yang berada pada kategori yang sama. Rerata minat belajar mahasiswa pada kelompok eksperimen sebesar 4,21 (sangat baik), sedangkan rerata pada kelompok kontrol sebesar 4,08 (baik). Selain itu, berdasarkan angket respon mahasiswa terhadap pembelajaran e-learning diperoleh rerata sebesar 4,51 (sangat baik).

Sesuai dengan Peraturan Menteri Kesehatan RI No. 492/Menkes/Per/IV/2010 tentang Persyaratan Kualitas Air Minum, kesadahan dalam air layak minum tidak dapat lebih dari nilai baku mutu sebesar 500 mg/l. Tingginya kadar kapur didaerah Wonogiri yang dapat menyebabkan terganggunya kesehatan menimbulkan kesadaran masyarakat untuk mengolah air minum. Oleh karenanya dilakukan program pengabdian kepada masyarakat (PPM) di daerah kelurahan Giritontro, Kabupaten Wonogiri yang bertujuan mengangani masalah kesadahan (kadar kapur) dalam air minum dengan menggunakan Biosand Filter. Pada PPM ini, diperoleh hasil bahwa teknologi Biosand Filter dapat mengurangi tingkat kesadahan hingga 78%.

Beberapa daerah di Wonogiri memiliki tanah yang mengandung kapur, sementara itu sebagian masyarakat mengonsumsi air yang berasal dari dalam tanah. Pada kegiatan pengabdian kepada masyarakat tahun 2016 ditemukan permasalahan dalam masyarakat di kelurahan Wonogiri yaitu sulitnya mendeteksi adanya kapur dalam air yang mereka konsumsi. Sebagai akibatnya banyak masyarakat yang menderita penyakit dalam yang diakibatkan pengendapan kapur di dalam tubuh mereka seperti penyakit ginjal. Oleh karenanya, tim PPM Fakultas MIPA Universitas Negeri Yogyakarta membangun sistem pendeteksi adanya kapur dalam cairan berbasis Light Emitting Diode (LED) dan Light Dependent Resistor (LDR). LED digunakan untuk menyinari cairan dengan kadar kapur yang berbeda-beda, kemudian LDR akan mendeteksi cahaya LED yang melewati cairan tersebut. Besar kecilnya nilai luaran LDR akan bergantung kadar kapur dalam cairan. Masyarakat sangat antusias dan mulai menggunakan alat ini untuk mendeteksi adanya kapur di air yang mereka konsumsi. Kata kunci: Kesadahan, LDR, LED Workshop On Detector of Water Hardness Based On Light Dependet Resistor In Giritontro Village, Giritontro District, Wonogiri RegencyAbstract Some areas in Wonogiri contain hardness in its soil, while some people consume water that come from the soil. In community service activity in 2016, we found problems in the community in Giritontro, Wonogiri that is the difficulties to detect the hardness in the water that people consume. As a result, many people who suffer from internal diseases caused by the deposition of lime in their bodies such as kidney disease. Therefore, the PPM team of the Faculty of Mathematics and Natural Sciences of Yogyakarta State University built a hardness detection system in liquid based Light Emitting Diode (LED) and Light Dependent Resistor (LDR). LEDs are used to irradiate fluids with different lime levels, then LDR will detect the LED light passing through the liquid. The size of the LDR output value will depend on the lime content in the liquid. People are very enthusiastic and start using this tool to detect the presence of limestone in the water they consume. Keywords: Hardness, LDR, LED
