Penelitian ini bertujuan untuk mengetahui efektifitas model Problem Based Learning dan Problem Solving terhadap kemampuan kemampuan berpikir kreatif pada siswa kelas 4 SD. Penelitian ini termasuk penelitian eksperimen semu. Uji prasyarat menunjukan kedua kelompok homogen dan berdistribusi normal. Uji T menggunakan uji t Independent Sample Test menunjukan t hitung > t tabel yaitu 10,148 > 2,0281 dan signifikan 0,000 < 0,05 yang berarti H0 ditolak dan Ha diterima. Hal ini menunjukan adanya perbedaan efektivitas yang signifikan. Selanjutnya dilakukan uji normalitas gain yang menunjukan bahwa model Problem Based Learning lebih efektif dibanding model Problem Solving terhadap kemampuan berpikir kreatif.

Hasil penelitian dapat disimpulkan bahwa penerapan model pembelajaran Teams Games Tournament (TGT) dapat meningkatkan keaktifan dan hasil belajar IPA siswa kelas V SD N Tegalrejo 01.
AbstrakPrevalensi panjang badan lahir pendek di Indonesia masih tinggi dan menjadi masalah kesehatan masyarakat yang disebabkan oleh pelbagai faktor secara langsung dan tidak langsung serta berdampak luas dan berkelanjutan dalam siklus kehidupan. Penelitian menggunakan data Riset Kesehatan Dasar (Riskesdas) 2013 dengan pendekatan potong lintang bertujuan mengetahui mekanisme hubungan berbagai variabel laten terhadap prevalensi panjang badan lahir pendek. Sampel adalah 497 kabupaten yang diagregat dari data individu, yaitu anak lahir dari ibu berusia 15 hingga 49 tahun dengan kriteria anak kandung dan lahir tunggal. Pemodelan menggunakan Structural Equation Modelling. Kehamilan berisiko tinggi berhubungan positif langsung dengan prevalensi panjang badan lahir pendek (r = 0,279; nilai p = 0,014). Pemanfaatan pelayanan kesehatan berhubungan positif tidak langsung dengan prevalensi panjang badan lahir pendek melalui kehamilan berisiko tinggi (r = 0,135; nilai p = 0,029). Sosial ekonomi tidak berhubungan signifikan dengan prevalensi panjang badan lahir pendek (r = -0,087; nilai p = 0,156), namun akan berhubungan bila melalui mekanisme hubungan pemanfaatan pelayanan kesehatan (r = 0,653; nilai p = 0,0001) dan kehamilan berisiko tinggi (r = 0,759; nilai p = 0,0001). Upaya intervensi perlu difokuskan pada pencegahan kehamilan berisiko tinggi melalui perbaikan status gizi dan kesehatan ibu sejak usia remaja untuk menurunkan prevalensi panjang badan lahir pendek. Kata kunci: Kehamilan, panjang badan lahir pendek, siklus kehidupan AbstractThe prevalence of short birth length in Indonesia still high and it becomes a public health problem caused by any direct and indirect factors as well as having a wide and sustainable effect in life cycle. The study used Basic health system (Riskesdas) 2013 data with a cross-sectional approach aiming to find out the mechanism of the relation between any latent variables to the short birth length prevalence. Samples were 497 districts aggregated from individual data that were children children born by 15 -49 year-old mothers with biological children and single birth criteria. The modelling used Structural Equation Modeling. High-risk pregnancy had a direct positive relation with the prevalence of short birth length (r = 0.279; p value= 0.014). The use of health services had an indirect positive relation with short birth length prevalence through high-risk pregnancy (r = 0.135; p value= 0.029). Social economy did not have any significant relation with the prevalence of short birth length (r = -0.087; p value = 0.156), but would be related if through the mechanism of health service use (r = 0.653 ; p value = 0.0001) and high-risk pregnancy (r = 0.759 ; p value = 0.0001). Efforts of intervention need to be focused on prevention of high-risk pregnancy through improvement of nutritional and health status of mothers since teenager in order to reduce short birth length prevalence.

Kedulan Site is the buried and ruined 9th century Mataram Hindu Kingdom temple, located in Tirtomartani Village, Kalasan District, Sleman Regency, Yogyakarta Special Province. This temple was incidentally discovered by sand diggers on 24 November 1993 under several meter thick of fluvio-volcanic deposit of the modern Merapi. Several technical studies were needed to carefully excavate the temple, including geology and geophysical approaches. One of the geophysical method have been applied was ground penetration radar (georadar). This method uses radar technology to obtain a continuous profile of the shallow sub-surface and thus allows scientists to image soil substratums based on differing dielectric constants. Georadar investigation by Department of Geological Engineering, Faculty of Engineering, Universitas Gadjah Mada, was conducted on 4 December 2007. The main purpose was to identify the location of the outer stone fence as an estimation to define the temple site area to be excavated. About one line was chosen to cross the site in north-south direction in a distance of 328 m. Two runs were completed on the same line but different courses, i.e. forward and backward, where one was checked with another. The result indicates the presence of the outer stone fence was possibly buried in a depth of 7 m. It was located about 40 m distance outside the inner stone fence. Assuming the fences were quadrangle relative to the main temple, hence it is estimated that the site area to be excavated is about 13.830 m² and total 96.808 m³ gravels and sands to be removed.
