PENERAPAN PENDEKATAN KETERAMPILAN PROSES DALAM PENGAJARAN BIOLOGI UNTUK MENGETAHUI HASIL BELAJAR SISWA PADA POKOK BAHASAN EKOSISTEM KELAS VII DI SMPN 1 TALUN
Pendidikan IPA sebagai salah satu contoh pendidikan secara utuh dan
menyeluruh. Proses IPA berkaitan dengan keterampilan proses dan kegiatan
ilmiah yang dapat berupa penelitian, percobaan atau praktikum. Pembelajaran IPA
pada pokok pembahasan ekosistem sangat dibutuhkan suatu pendekatan
keterampilan proses, dengan pendekatan tersebut siswa akan lebih paham dengan
materi yang diajarkan karena dalam proses belajarnya siswa akan terjun langsung
melakukan observasi, interprestasi, klasifikasi, berkomunikasi, dan berhipotesis.
Tujuan dari skripsi ini yaitu untuk mengetahui bagaimana hasil belajar
siswa yang menggunakan dan tidak menggunakan KPS, untuk mengetahui
perbedaan hasil belajar siswa antara yang menggunakan dan yang tidak
menggunakan KPS, dan untuk mengetahui perbedaan penerapan hasil observasi
dari 5 aspek yaitu observasi, interpretasi, klasifikasi, berkomunikasi, dan
berhipotesis.
Penelitian ini menggunakan dua kelas yaitu kelas eksperimen dengan
menerapkan pendekatan keterampilan proses sains dan kelas kontrol dengan
menggunakan metode ceramah. Subjek penelitian ini adalah siswa kelas VII H
dan VII G masing-masing berjumlah 30 siswa, dan pengambilan sampelnya

On the Rebrightenings of Classical Novae during the Early Phase
We report on the spectral evolution of 6 classical novae, V1186 Sco, V2540
Oph, V4745 Sgr, V5113 Sgr, V458 Vul, and V378 Ser, based on the low-resolution
spectra obtained at the Fujii-Bisei Observatory and the Bisei Astronomical
Observatory, Japan. In the light curves, these 6 novae show several
rebrightenings during the early phase lasting ~10 days after the first maximum
in fast novae, and ~100 days in slow novae. The early spectra of all of these
novae had emission lines with a P-Cygni profile at the maximum brightness. The
absorption component of the P-Cygni profiles then disappeared after the
maximum, and reappeared when the novae brightened to the next maximum. We
suggest that the re-appearance of the absorption component at the rebrightening
is attributable to re-expansion of the photosphere after it once shifts
sufficiently inside. From the light curves, we found that the time intervals of
the rebrightenings of these 6 novae show a similar systematic trend, which is
applicable to all types of novae: fast and slow, and Fe II type and hybrid
type. Moreover, we note the difference between the spectra at the
rebrightenings during the early phase and at the rebrightening in V2362 Cyg,
and at the oscillation during the transition phase in V1494 Aql, which means
difference of the physical mechanism of the rebrightening during the early
phase and the later oscillations.Comment: 11 pages, 15 figures, accepted for publication in PAS
Fast Freenet: Improving Freenet Performance by Preferential Partition Routing and File Mesh Propagation
The Freenet Peer-to-Peer network is doing a good job
in providing anonymity to the users. But the performance
of the network in terms of download speed and request hit
ratio is not that good.
We propose two modifications to Freenet in order to improve
the download speed and request hit ratio for all participants.
To improve download speed we propose Preferential
Partition Routing, where nodes are grouped according
to bandwidth and slow nodes are discriminated when routing.
For improvements in request hit ratio we propose File
Mesh propagation where each node sends fuzzy information
about what documents it posesses to its neigbors.
To verify our proposals we simulate the Freenet network
and the bandwidth restrictions present between nodes as
well as using observed distributions for user actions to show
how it affects the network.
Our results show an improvement of the request hit ratio
by over 30 times and an increase of the average download
speed with six times, compared to regular Freenet routing
Spectral Evolution of the Unusual Slow Nova V5558 Sgr
We report on the spectral evolution of the enigmatic, very slow nova V5558
Sgr, based on the low-resolution spectra obtained at the Fujii-Bisei
Observatory and the Bisei Astronomical Observatory, Japan during a period of
2007 April 6 to 2008 May 3. V5558 Sgr shows a pre-maximum halt and then several
flare-like rebrightenings, which is similar to another very slow nova V723 Cas.
In our observations, the spectral type of V5558 Sgr evolved from the He/N type
toward the Fe II type during the pre-maximum halt, and then toward the He/N
type again. This course of spectral transition was observed for the first time
in the long history of the nova research. In the rebrightening stage after the
initial brightness maximum, we could identify many emission lines accompanied
by a stronger absorption component of the P-Cygni profile at the brightness
maxima. We found that the velocity of the P-Cygni absorption component measured
from the emission peak decreased at the brightness maxima. Furthermore, we
compared the spectra of V5558 Sgr with V723 Cas, and other novae which
exhibited several rebrightenings during the early phase.Comment: 8 pages, 7figures, accepted for publication in PAS
Studi Etnomatematika: Eksplorasi Konsep Teorema Phytagoras pada Budaya Palembang
Ethnomathematics is a study that combines mathematics and culture. Culture is a legacy passed down from ancestors that becomes a characteristic or characteristic of a particular region, one of the regions that has characteristics that are famous for its culture is the city of Palembang. Palembang city has various cultures that are in great demand by outsiders such as the Limas traditional house and jumputan cloth. Discussing about culture, this is certainly inseparable from learning concepts found in everyday life, one of which is the concept of learning mathematics. Where in this case the researcher takes the concept of mathematics on the phytagorean theorem associated with Limas houses and jumputan cloth. The type of research that researchers use is ethnographic qualitative research. Data sources are primary data and secondary data. Data collection techniques through interviews, observations and documentation. The data obtained was then analysed by data reduction, data presentation, and conclusions and verification. The result of this research is that Palembang culture, namely the Limas house roof, has the application of the phytagoras theorem concept. In the motifs of jumputan fabric patterns and the plan of the Limas house looking sideways contains the concept of proving the truth of the phytagoras theorem
ISLAM POLITIK DALAM MEDIA MASSA Sebuah Telaah Kritis atas Pemberitaan Ideologi Politik dalam Kasus-kasus Keagamaan
Istilah Islam politik merupakan sebuah konsep yang digunakan untuk menjelaskan gejala sosial politik dikalangan aktivis atau sekelompok individu yang mendasarkan gerakan mereka dengan ideologi. Seiring dengan itu, dalam sorotan media massa, wacana Islam politik iu sudah ditentukan oleh hubungan antara; media, wacana Islam politik, serta audiensnya yang dipengaruhi oleh relasi-relasi dibaliknya seperti; kebijakan redaksional media. Tulisan ini mencoba untuk menjawab relasi apa yang melatar belakangi wacana Islam politik dihadirkan di harian Kompas dan harian Republika tentang penyerangan warga Ahmadiyah di Cekeusik, Banten pada 06-02-2001, Penyerangan Gereja di Temanggung, Jawa Tengah 07-02-2011, penyerangan warga Syiah di Sampang, Jawa Timur 28-08-2012, berita partai-partai Islam setelah verifikasi komisi pemilihan umum (KPU) Januari 2013 08-01-2013. Berdasarkan analisis isi yang berparadigma analisis wacana kritis, kedua media nasional ini (harian Kompas dan harian Republika) samasama mampengaruhi pembaca. Bedanya, harian Kompas membingkai wacana ini kedalam dinamika ke-Indonesia-an dalam kerangka kebinekaan dan kesatuan bangsa sedangkan harian Republika membungkus wacana Islam politik kedalam dinamika keislaman. Walaupun demikian kedua media ini sama-sama menekankan arti penting peran pemerintah dalam penanganan kasus Islam politik di Indonesia. Tulisan ini juga bisa dijadikan sebagai bahan kritis dalam pembacaan atas wacana Islam politik di media massa, khususnya di Indonesia
