Schematic Representation: How Students Creating IT?

Penelitian ini bertujuan untuk mendeskripsikan proses terbentuknya representasi skematis murni dan representasi skematis campuran yang diciptakan oleh siswa selama menyelesaikan word problem. Jenis penelitian yang digunakan adalah kualitatif yang bersifat deskriprif. Dalam penelitian ini melibatkan 45 siswa kelas 8. Sedangkan untuk memilih subjek tidak dipilih secara acak, namun dipilih berdasarkan kemampuan siswa dalam menciptkan representasi skematik. Pengumpulan data dilakukan dengan meminta siswa untuk menyelesaikan Tugas Pemecahan Masalah secara think aload, yaitu siswa diminta untuk menyuarakan apa yang dipikirkannya. Selain itu siswa juga menuangkan pikirannya mengunakan kertas dan pensil. Hasil penelitian ini menunjukkan bahwa proses representasi skematis murni diciptakan siswa dengan membuat gambar skema berupa garis besar dari masalah dan dilengkapi dengan beberapa keterangan pokok yang ada dalam masalah. Sedangkan proses representasi skematis campuran diciptakan siswa dengan membuat gambar skema yang dilengkapi dengan keterangan-keterangan dan gambar nyata yang sesuai dengan situasi dalam masalah. Kedua jenis representasi skematis ini sangat efektif dalam membantu siswa dalam menyelesaikan word problem

"Is Personal Debt Sustainable?"

The long economic expansion was fueled by an unprecedented rise in private expenditure relative to income, financed by a growing flow of net credit to the private. On the surface, it seemed that the growing burden of the household sector's debt was counterbalanced by a spectacular rise in the relative value of its financial assets, but this was never a match among equals, and the great meltdown in the financial markets has proved this imbalance to be true. The private sector has dramatically cut back its acquisition of new credit and reversed the path of its financial balance, but this adjustment has been uneven within the sector: the business sector suffered a huge drop in investment while the household sector has continued to borrow.

Tata Perdagangan Perikanan Indonesia Melalui Introduksi Standar Internasional Seafood Ecolabeling

Ecolabel is certification products give information to consumers that product life cycle in environmental effect negative a relatively small. World trade of fishery has shaded various provisions and regulation to keep the environmental sustainability (UNCLOS, CITES, act fishery). The arrangement trade fishery in Indonesia through a system of national logistics fish require useful aspect on this. Ecolabeling as one of the application of preserve the living environment more practical and interesting. Implementation seafood ecolabeling on trade fish in Indonesia can practiced on system logistics fish national which includes the application on fishing vessel, fish auction center, fish culture, fish processing and fish market. The application of ecolabelling manifested by sharing form model label the inspired, interesting and raises of awareness on the environment

"How Fragile is the U.S. Economy?"

As we projected in a previous strategic analysis, the U.S. economy experienced growth rates higher than 4 percent in 2004. The question we want to raise in this strategic analysis is whether these rates will persist or come back down. We believe that several signs point in the latter direction. In what follows, we analyze the evidence and explore the alternatives facing the U.S. economy.

Prioritas Penentuan Nilai Pendidikan Karakter dalam Pembelajaran Sastra Remaja

Penelitian bertujuan untuk mendeskripsikan sikap dan pendapat guru SMP/MTs terhada penentuan prioritas nilai pendidikan karakter dalam pembelajaran sastra remaja, genre, dan stratepenyajian bahan ajar. Subjek penelitian adalah guru Bahasa Indonesia di DIY dengan sampel sebanya30 orang, hadir 24 orang, dari keempat kabupaten dan satu Kota Madya. Pengumpulan data dilakukalewat angket, wawancara, dan sumbang saran di FGD. Data dianalisis dengan teknik deskriptkualitatif dan penghitungan persentase. Hasil penelitian adalah sebagai berikut. (1) Penentuan prioritanilai-nilai karakter perlu untuk memudahkan pemantauan, pengawasan, dan penilaian. Nilai karaktyang dipilih guru adalah nilai religius, jujur, cinta tanah air, peduli lingkungan, tanggung jawab, serkreatif, gemar membaca, disiplin, dan mandiri. (2) Pemilihan genre tampak masih terpola padpembagian sastra kanonik-dewasa, namun ia harus mencakup keseluruhan genre sastra remaja. (3)Penyajian bahan ajar ditekankan pada yang mendasarkan diri pada prinsip pembelajaran kontekstuadan multintelenjjens dengan teknik penilaian otentik

Fire Safety Analysis of a Railway Compartment using Computational Fluid Dynamics

Trains are considered to be the safest on-land transportation means for both passengers and cargo. Train accidents have been mainly disastrous, especially in case of fire, where the consequences are extensive loss of life and goods. The fire would generate smoke and heat which would spread quickly inside the railway compartments. Both heat and smoke are the primary reasons of casualties in a train. This study has been carried out to perform numerical analysis of fire characteristics in a railway compartment using commercial Computational Fluid Dynamics code ANSYS. Non-premixed combustion model has been used to simulate a fire scenario within a railway compartment, while Shear Stress Transport k-ω turbulence model has been used to accurately predict the hot air turbulence parameters within the compartment. The walls of the compartment have been modelled as no-slip stationary adiabatic walls, as is observed in real life conditions. Carbon dioxide concentration (CO2), temperature distribution and air flow velocity within the railway compartment has been monitored. It has been observed that the smoke above the fire source flows to both sides of the compartment. The highest temperature zone is located downstream the fire source, and gradually decreases with the increase in the distance from the fire source. It can be seen that CFD can be used as an effective tool in order to analyse the evolution of fire in railway compartments with reasonable accuracy. The paper also briefly discusses the topical reliability issues

Kajian Keinjektifan Modul (Modul Injektif, Modul Injektif Lemah, Modul Mininjektif)

. Let be an -module. An -module is called injective if for any monomrphism and for any homomorphism there exists a homomorphism such that . We say that an -module is weakly-injective if is weakly -injective for every finitely generated module . An -module is called mininjective if every homomorphism , there exists a homomorphism such that , with is simple ideal of . In this paper, we give some characterizations and properties of injective modules, weakly-injective modules, and mininjective modules. In particular, they have different characterizations for their infinite direct sum
