Abstract

Smart Grid is an advanced two way data and energy flow capable of self-healing, adaptive, resilient, and sustainable with prediction capability of possible fault. This article aimed to disclose Smart Grid communication in a logical way to facilitate the understanding of each component function. The study was focused on the improvement, advantages, common used design, and possible feature of Smart Grid communication components. The results of the study divide the Smart Grid communication application into two main category i.e. measurement equipment and network architecture. Measurement equipment consists of Advance Metering Infrastructure, Phasor Measurement Unit, Intelligent Electronic Devices, and Wide Area Measurement System. The network architecture is divided based on three hierarchies; local area network for 1 to 100 m with 100 kbps data rate, neighbour area network for 100 m to 10 km with 100 Mbps data rate, and wide area network for up to 100 km with 1 Gbps data rate. More information is provided regarding the routing protocol for each network from various available protocols. The final section presents the energy and data flow architecture for Smart Grid implementation based on the measurement equipment and the network suitability. This article is expected to provide a comprehensive guide and comparison surrounding the technologies supporting Smart Grid implementation especially on communication applications.

Abstract

The whole cell immobilization in ethanol fermentation can be done by using natural carriers or through synthetic carriers. All of these methods have the same purpose of retaining high cell concentrations within a certain defined region of space which leads to higher ethanol productivity. Lignocellulosic plant substance represents one of highly potential sources in ethanol production. Some studies have found that cellulosic substances substances can also be used as a natural carrier in cell immobilization by re-circulating pre-culture medium into a reactor. In this experiment, rice hulls without any treatment were used to immobilize Saccharomyces cerevisiae through semi solid state incubation combined with re-circulating pre-culture medium. The scanning electron microscopy (SEM) pictures of the carrier show that the yeast cells are absorbed and embedded to the rice hull pore. In liquid batch fermentation system with an initial sugar concentration of 50 g/L, nearly 100% total sugar was consumed after 48 hours. This resulted in an ethanol yield of 0.32 g ethanol/g glucose, which is 62.7% of the theoretical value. Ethanol productivity of 0.59 g/(L.h) is 2.3 fold higher than that of free cells which is 0.26 g/(L.h). An effort to reuse the immobilized cells in liquid fermentation system showed poor results due to cell desorption in the first batch which led to high sugar concentration inhibitory effect in the second batch fermentation. This might be solved by using semi solid fermentation process in the future work.

Abstract

Pembelajaran tematik adalah ilmu yang mempelajari semua mata pelajaran pokok yang dikelompokkan dalamsatu tema pembelajaran. Hasil belajar tematik dilakukan dengan observasi, eksperimen serta penyimpulanagar mengetahui perbedaan nilai yang diperoleh siswa melalui kegiatan pembelajaran dikelas denganmenerapkan model tipe Picture And Picture dan Example Non Example. Model ini adalah modelpembelajaran yang memiliki kesamaan memakai media gambar dalam pengaplikasiannya. Penelitian inibertujuan untuk membuktikan ada atau tidaknya perbedaan pengaruh yang signifikan antara model tipePicture And Picture dan Example Non Example pada nilai hasil belajar tematik. Jenis penelitian ini adalaheksperimen jenis quasi exsperimental dengan desain eksperimen jenis Nonequivalent Control Group Design.Teknik pengumpulan data dilakukan dengan memakai tes (pretest dengan posttest). Populasi penelitian iniadalah Gugus Ki Hajar Dewantara dengan sampelnya siswa kelas IV SDN Sugihan 01 dan SDN Sugihan 04.Hasil penelitian menunjukkan bahwa tidak terdapat perbedaan yang signifikan antara penerapan modelpembelajaran tipe picture and picture dan example non example terhadap hasil belajar tematik kelas IV diSDN Gugus Ki Hajar Dewantara. Hal itu dibuktikan dengan melakukan uji T-test posttest yang menyatakanbahwa nilai sig (2-failed) sebesar 0,297 ≥ 0,05, yang artinya Ho diterima dan Ha ditolak
