Abstract

Jusman, (A 121 08 110) Developing Students’ Skill in Writing Procedure Text by Using Sequence Pictures of the Ninth Grade Students at SMP Negeri 8 Pasangkayu under supervision of MochtarMarhum and Muhsin. The objective of this research was to find out whether the use of sequence pictures can improvewriting ability of the ninth grade students at SMP Negeri 8 Pasangkayu. This research employed true experimental design. It involved two class: experimental and control class. The sample of this research was the ninth grade students at SMP Negeri 8 Pasangkayu. It was selected with a random sampling technique. The instrument of data collection was a test which was given and distributed to the research sample as pre-test and post-test. The pre-test was given before the treatment to measure the students’ basic knowledge and the post-test was administered after conducting 8 meetings of treatment to measure the improvement of students’ writing skill. The means score of the students of experimental class in pre-test is 5.13 and post-test is 6.57, while the mean score of control class in pre-test is 4.92 and post-test is 5.93. By applying 0,05 level of significance and 48 (25 + 25 – 2) degree of freedom (df), the researcher found that the t-counted value (3.14) was greater than t-table value (1.992). It means that the hypothesis of this research was accepted. It indicated that the students’ writing skill in procedure text can be developed through sequence pictures. Keywords: Developing, Writing Skill, Procedure Text, Sequence Pictures.

This research aims to production of chitinase from thermophylic bacteria that living in Bora hot spring  and to determine of chitinase extracts activity. The research was began with rejuvenated of B1211 bacteria isolates on MSM agar media.  The B1211 isolates was used to production of chitinase extracts on MSM broth media with chitin colloidal concentration of 0.25%, 0.5%, 1%, 2%, 4% and incubation temperature of 30oC (rt), 37oC, 50oC, and 60oC for 3 days. The chitinase activity were analyzed based on N-acetyl-D-glucosamine standard. The results was showed that B1211 bacteria isolates is potential isolate for production chitinase. The highest activity of chitinase from B1211 bacteria isolates of 0.75 U/mL for chitin colloidals concentration of 1% and temperature of 60oC.Keywords : Bora, hot spring, bacteria, thermophylic, B1211 isolates, chitinase.

Abstract

This study aims to determine some physical properties Inceptisols Watutela in relation to organic matter and heating temperature. The research method is through laboratory experiments using completely randomized design (CRD), which consists of two factors. The first factor is the treatment of soil organic matter derived from goat droppings and the second factor is the heating temperature treatment. Each treatment consists of three levels and repeated 6 times to obtain         54 experimental units. Treatments organic matter goat manure include: without organic matter or Control (A0), organic matter with a level of 2.5% by weight of the ground (A1), and organic matter to the level of 5% of the weight of the soil used in the research (A2). Level-the level used in the heating temperature treatment includes heating at room temperature (P0), heating in an oven at a temperature of 50°C (P1) and heating it in an oven at 70°C (P2). Data processing studies to determine the effect of treatment among study done using ANOVA F test, subsequent treatment effect was tested further by honestly significant difference test (HSD). The research variables were observed consisting of: saturated soil water content, water content of field capacity, soil bulk density, soil porosity and soil aggregate stability. The results showed that the characteristics of Inceptisols Watutela the initial soil analysis showed a sandy loam texture, organic C content of 0.89% (relatively low). Based on observations showed that organic matter goat droppings and the heating temperature individually provide highly significant effect on all variables observed physical properties of soil. The interaction between organic material and the heating temperature very significant effect on saturated soil water content and soil porosity. On the other hand, the interaction between organic matter and heating temperature effect no significant effect on the measurement of field capacity moisture content, soil bulk density and soil aggregate stability Keywords: Inceptisol, Organic Material, Physical Properties Of Soil,Temperature

Abstract

The objectives of the study were to obtained the optimal combination of starch concentration and reaction time in the synthesis of phosphorylated arenga starches. Synthesis of phosphorylated arenga starches using sodium tripolyphosphate reagents and arenga starch 20 and 30% (b/v) with variations of time reaction 30 and 45 min. Chemical, functional and rheological characteristics of phosphorylated arenga starcheswere investigated i.e. percent phosphate and degree of substitution (DS), binding of phosphate groups using FourierTransform Infrared (FTIR), water and oil holding capacity (WHC, OHC), swelling power and solubility and emulsion separation volume. The results showed a combination of 30% arenga straches with a reaction time 45 min were optimal combination that to produced phosphorylated arenga starches with the highest of phosphate content (2.710%) and DS 0.147. The FTIR spectra of phosphorylated arenga starches have been a change in vibration of OH groups that replace the reaction of phosphate groups with OH in starch molecules. WHC and swelling power increased, but solubility phosphorylated arenga starches decreased with the in increasing combination of arenga starch concentration and reaction time. The emulsion separation volume the most stable at the combination of highest arenga starch concentration and the long reaction time. Phosphorylated arenga starches which produced were used as emulsifiers for food aplication

Abstract

Pelestarian lingkungan hidup merupakan kebutuhan yang tidak dapat ditunda lagi dan bukan hanya tanggung jawab negara saja, melainkan tanggung jawab setiap insan di bumi. Upaya pemerintah untuk mewujudkan kehidupan adil dan makmur bagi rakyatnya, harus disertai dengan tindakan pencegahan kerusakan lingkungan. Berbagai program pembangunan berkelanjutan dilakukan sebagai bagian perlindungan kualitas lingkungan. Salah satu program pembangunan berkelanjutan di bidang lingkungan, adalah pendidikan lingkungan hidup yang dimulai pada tingkat SD, SMP, SMA/SMK. Artikel ini membahas gambaran pelaksanaan program Adiwiyata. Program adiwiyata yaitu sekolah yang peduli terhadap lingkungan sekitarnya, yang meliputi sekolah bersih, sehat, indah serta lingkungan berwawasan global yang mengharapkan semua orang ataupun warga sekolah dapat sadar akan betapa pentingnya lingkungan sekitar. Maka dari itu sekolah yang menjalankan program adiwiyata memiliki kebijakan pengintegrasi pendidikan lingkungan hidup, seperti pada sekolah dasar pertiwi di kota makassar yang menjadi penelitian ini.
