PENGARUH PENAMBAHAN KULIT COKLAT TERHADAP SIFAT FISIS KERAMIK BERPORI

ABSTRACT Research on the effect of adding rind kakao on the physical properties of porous ceramics is motivated by the increasing number of cocoa pods in Indonesia and has not been fully utilized by farmers and the surrounding community. Therefore, this study aims to overcome environmental problems as well as increase the economic value of Rind Kakao waste into porous ceramics. The first method used was to reduce the particle size of clay and Rind Kakao to 200 mesh with a sieve. Then the two ingredients are mixed and the results of the mixing are printed. The results of the printing are activated at a temperature of 6000C. The results of the activation are then ready to be tested for physical properties such as porosity and SEM. The porosity and SEM test results showed that porous ceramics with a variation of 70 clay + 30 Rind Kakao had the best porosity percentage of 55.60% and had the smallest pore size of 3.37 µm. This is due to the presence of pore marks left by the Rind Kakao which has turned ash due to the activation of the porous ceramic at 6000C. Keywords: Porous Ceramics, Rind Kakao, Cla

ANALISIS MATERI PADA KURIKULUM DAN BUKU PAKET BAHASAINDONESIA SMA

ABSTRACT The curriculum is a milestone in the world of education. All educational institutions make the curriculum a foundation in improving the quality of education.. The change of the Minister of Education has also resulted in changes to the curriculum and education system. Whether an educational institution is good or not depends on how to run the programs that are already in the curriculum. Not only that, the curriculum is also a guideline and guide for teachers, schools and the community regarding the type, scope and order of content, as well as the national education process. In the history of its development, the curriculum in Indonesia has had very significant and drastic changes. The curriculum in Indonesia after Indonesia's independence in 1945 has changed ten times, namely in 1947, 1952, 1964, 1968, 1975, 1984, 1994, 2004, 2006, and 2013. For now, Indonesia has implemented and implemented the 2013 Curriculum ( K.13) which in the curriculum requires students to be more creative and innovative. In this research, it leads to analyzing the material taught in high school in the Education Unit Level Curriculum (KTSP) and the 2013 Curriculum (K.13). Keywords: Curriculum, KTSP, K.1

Kajian Makanan Ikan dan Waktu Makan Tor (Tor soro Valenciennes 1842) Di Sungai Asahan

The Tor fish food study conducted on the Asahan River in this study determined three stations by purposive sampling, namely the distribution of locations based on river characteristics, and fish habitat in the Asahan River area. Data was collected from April - July 2017 this study consisted of field research and laboratory research. Field research was carried out on the Asahan River. Sampling of fish using fishing gear in the form of a mesh measuring three meters long, gill nets with three meshes (¾, 1½ and 2 inches) measuring 20 m long and 2 meters wide. The purpose of this study was to examine the composition of food and the time of eating fish. Tor fish caught during the study were 128 individuals. The total length (TL) range of Tor fish is between 70 - 210 mm, and the weight range is between 20 - 205 gr. Tor fish include omnivorous fish that tend to be herbivores with their main food being phytoplankton, followed by crustaceans, insects, rotifers, oligochaeta. Tor fish are diurnal fish with active time for fish, which is in the morning. In conducting foraging activities it is suspected that tor fish use the sense of sigh

EKTOPARASIT IKAN MAS KOKI ORLANDA (CARRASIUS AURATUS)DARI TOKO IKAN HIAS (STUDI KASUS DI KECAMATAN KISARAN BARAT KABUPATEN ASAHAN)

ABSTRACT The aquarium's ornamental fish trade or business has an economic opportunity to earn up to hundreds of millions of rupiah.Orlanda goldfish (Carrasius auratus) is the most in-demand ornamental fish by hobiest aquarium fish compared to other ornamental fish sold from ornamental fish shops in West Kisaran District.Although the ornamental fish business is very profitable but the trade/business of the fish can be detrimental because the goldfish has the opportunity to be a parasitic carrier agent. The higher the intensity of the fish trade then the chance of the spread of parasites to infect aquarium fish the greater.The study aims to gain information and knowledge about the types, prevalence, intensity and organs infected with  carp ectoparasites from ornamental fish stores as a preventive measure in the spread of parasites.The method used is the survey method. Fish samples are obtained from ornamental fish stores and observed under a microscope by scraping mucus from the outer organs. Ectoparasites found in  carp (C. auratus) are identified to see their type, prevalence and intensity.The types of ectoparasites found to infect C. auratus are the Protozoans (Trichodina sp, Ichtyopthirius multifilis and Chilodenella sp), Monogenea (Gyrodactylus sp and Dactylogyrus sp) and Copepoda (Metanauplius Larnea sp).Dactylogyrus sp is the ectoparasite with the highest prevalence of 76.47% and this ectoparasite is found only in the gills.The next high prevalence is Gyrodactylus sp with a prevalence of 52.94%, this ectoparasite was found to infect the skin and tail fins.The results of the study were published in national seminars and national journals with ISSN. Keywords: Ektoparasit, Carrasius auratus, prevalens
