Analisis Pemanfaatan Bahan Alam Sebagai Media Pembelajaran Untuk Mengembangkan Motorik Halus Pada Anak Usia 4-5 Tahun Di Tk Islamiyah Pontianak Tenggara

This study aimed to describe the planning, implementation, fine motor development of children, constraints, as well as how to overcome the obstacles of learning that utilizes natural materials as a medium to develop fine motor skills of children aged 4-5 years in TK Islamiyah Pontianak Tenggara. This research method is descriptive method with qualitative approach. Subject of the study: the principal, two teachers and 21 children. The results showed: (1) planning learning, teachers determine the theme and purpose of learning, making RKH, prepare media and tools. (2) Implementation of learning, teachers provide an explanation of media and activities to be carried out, giving examples of tasks, as well as guiding the child. (3) Develop the fine motor skills of children, through taste with banana bark, leaves, and a collage with sand. (4) Constraints faced, looking for media in the form of grains because there are around TK, the child does not want to learn, and children were crying. (5) Overcoming obstacles that utilize natural materials that are around, advised children, and persuade a child to want to learn

Pengaruh Suhu Pengukusan Terhadap Sifat Fisika Kimia Tepung Ikan Rucah

This research was aimed to determine the best steamed temperature and to determine the steamed effect on phsycochemical of trash fish. The research was conducted on June-July 2014 in fishery processing laboratory and fishery chemical laboratory Faculty of Fisheries and Marine Science Riau University, and this research was conducted also in food laboratory Bogor Agriculture Institute. Trash fish was obtained from Tanjung Beringin Village, Rampah - North Sumatera. The metode used in this research was completely randomized design (CRD) with 3 treatments of steamed temperature S1 (100 ºC), S2 (90 ºC) and S3 (80 ºC).The results showed that the treatment S3 (80 ºC) of steamed temperature was the best treatment with absorption 126.67, white degree 33.67, pH 6.41 and yield 16.90. Chemical characteristic for ash content 17.72 %, water content 7.51%, protein content 50.95%, fat content 7.70 % and crude fiber 4.22%

Evaluation of non-viable biomass of Laurencia papillosa for decolorization of dye waste water

The uptake of fast orange dye by the red seaweed Laurencia papillosa has been demonstrated in order to explore its potential use as low-cost adsorbent. The adsorption kinetics of fast orange dye on the alga with respect to initial dye concentration, contact time, particle size and pH were investigated. The dye removal percentage increased from 25.92 to 67.08% and the equilibrium states were attained at almost 60 min within the experimental concentration range. The adsorption kinetic was analyzed using pseudo-first-order and pseudo-second-order models. The pseudo-second-order model was more appropriate to describe the sorption kinetics based on the relatively high values of the linear squared regression correlation coefficient. The nature of the possible adsorbent and fast orange interactions was examined by the Fourier transform infrared technique. This technique confirmed that hydroxyl, carboxyl, amine, sulfonyl, carbonyl and alkyl groups are responsible for the dye binding process. Significant increase in dye adsorption was observed with the decrease in sorbent particle size coupled with its large surface area. Maximum removal efficiency was determined to be 65.7% at a solution pH of 5. However, Laurencia papillosa proved to be a promising material for removing fast orange dye from aqueous solutions.Keywords: Dye adsorption, Macroalga, Laurencia papillosa, kineticsAfrican Journal of Biotechnology Vol. 12(17), pp. 2215-222
