Pengaruh model inkuiri terbimbing terhadap keterampilan proses sains pada materi kelarutan dan hasil kali kelarutan

Abstract: Penelitian ini bertujuan untuk mengetahui pengaruh penerapan model inkuiri terbimbing dalam pembelajaran terhadap keterampilan proses sains siswa di suatu SMA Negeri di Semarang tahun pelajaran 2015/2016, serta untuk mengetahui besarnya pengaruh tersebut. Populasi bersifat normal dan memiliki homogenitas yang sama sehingga pengambilan dua kelompok sampel menggunakan teknik cluster random sampling. Metode true-experimental digunakan dalam penelitian ini dengan desain eksperimen yaitu post-test only control group design. Data diambil menggunakan metode tes, observasi, dan kuesioner. Pada analisis tahap akhir, pengujian hipotesis menggunakan uji t pihak kanan. Skor rata-rata post-test kelas ekperimen sebesar 71,12 dan kelas kontrol sebesar 66,26. Dari hasil analisis data, diketahui adanya perbedaan yang signifikan antara keterampilan proses sains siswa kelas eksperimen dengan keterampilan proses sains siswa kelas kontrol. Analisis data post-test kedua kelas menunjukkan bahwa penerapan model inkuiri terbimbing dapat menigkatkan keterampilan proses sains siswa dengan koefisien determinasi 10%, sedangkan koefisien korelasi 0,32 termasuk kategori rendah. Maka dapat disimpulkan model inkuiri terbimbing dapat meningkatkan keterampilan proses sains siswa dengan indikator keterampilan proses sains tertinggi yaitu merancang percobaan.

Faktor Timbulnya Cedera Olahraga

Abstract: Olah raga tidak terlepas dari adanya gerakan yang selanjutnya akan melibatkan berbagai struktur/jaringan pada tubuh manusia, misalnya sendi, otot, meniscus/discus, kapsuloligamenter dan otot. Gerakan terjadi bilamana mobilitas serta elastisitas dan kekuatan jaringan penompang dan penggerak sendi terjamin. Semakin mobile suatu persendian mempunyai konsekuensi berupa semakin tidak stabilnya sendi tersebut. Ketidakstabilan suatu sendi akan mengakibatkan struktur sekitarnya mudah cedera apalagi bila elastisitas dan kekuatan jaringan penompang dan penggerak sendi tidak memadai. Stabilitas suatu persendian akan dipengaruhi oleh konfigurasi tulang pembentuknya, keadaan kapsuloligamenter, keadaan otot penggerak, tekanan intra artikuler, keadaan discus/meniscus, derajat kebebasan gerak serta pengaruh gaya gravitasi. Kejadian cedera bila tidak segera ditangani maka akan mengakibatkan cedera yang lebih parah. Kata Kunci : olahraga; cedera The sport is inseparable from the movement which in turn will involve a variety of structures / tissues in the human body, such as joints, muscles, meniscus / disc, ligament  of capsule, and muscle. The Movement happened how ever when mobility and tissue elasticity and strength and drive standard of joint. The more mobile a joint has the consequence of the increasingly unstable joints. Instability of a joint will result in surrounding structures easily injured, especially if the elasticity and strength of the network and drive joints standard inadequate. The stability of the joints will be influenced by: its constituent bones configuration, capsule of ligament circumstances, the state of muscle force, pressure intra articuler, state disc/meniscus, degrees of freedom of movement and the influence of gravity. Accident injury of sport if not have good treatment that is can make akut injury. Keywords : sport; injury

Abstract: This research aims to find and identify the 4 th level students’ science generic skill using guided inquiry learning in SMK Raja Permaisuri Bainun. This research method is descriptive qualitative method that explains the generic science skills indicators that have been studied through the Data taken from the research then Analyzed and summarized as research results. Profile of generic science skills valuation indicates that the indicator of student observation on acid and base material is high with the average of 81. Science Generic skills of symbolic language are classified with average of 73, while logical consistency and inference indicator are classified as high with average of 67 and 85 respectively. Overall, 4th Generic science skills of SMK Raja Permaisuri Bainin on acid and base material in guided inquiry learning is high enough with the average of 76.5. The analysis of students' cognitive learning outcomes guided inquiry learning was obtained in average of 73 and it indicated a high level of achievement. Furthermore, this result also indicated resources in the student's response to the guided inquiry learning that positively influences the students’ science generic skills.

Peran Kelompok Masyarakat dalam Rehabilitasi Ekosistem Mangrove di Pesisir Kota Semarang

Abstract: The coastal area of Semarang City has a strategic function for regional economic development. Due to land use change, the environmental quality of coastal area is damaged and declining. The environmental quality decline has affected the socio-economic quality of local community.

The study takes place in two kelurahans, namely Tugurejo and Mangunharjo, and applies a descriptive qualitative approach to figure out the local community role in the coastal environment rehabilitation. Data collection through a preliminary survey supported with a satellite imagery study covers up an appropriate ecosystem with the research substance. Then the following data analysis and interpretation uses Miles and Huberman interactive analysis method. The results show the significant role of the local community in coastal area quality management and improvement in Semarang City more effectively and efficiently. This relates to their active interactions in various community-based programs including wave-breaking instrument building and mangrove nursery and planting.
