Abstract

This study aims to determine the chemical characteristics of peat soil in various depths of water drainage. This research was conducted in Rasau Jaya General Village Rasau Jaya Sub-district, Kubu Raya Regency. Soil analysis was conducted at Soil Chemistry and Soil Fertility Faculty of Agriculture, University of Tanjungpura Pontianak. Soil sampling is done by disturbed soil sampling method and done by diagonal. Soil sampling was conducted on 3 plot of land observation, consisting of P0 without drainage channel, P1 drainage water channel depth 30 cm and P2 water depth of drainage channel 60 cm. Each plot is 40 x 50 m in size and there are 5 observation points. Each observation point there are 2 depths of 0-20 cm and 20 - 40 cm. The method used is descriptive data analysis to see comparison of chemical characteristics of peat soil in each plot of land P0, P1, and P2 which contained some water depth of drainage channel. The parameters observed in this study were soil reaction (soil pH), cation exchange capacity (CEC), base saturation (KB), N-total (%), P available (ppm), K (cmol (+) ?kg? ^ (-1)), Ca (%), Mg (%), C-Organic (%). Keywords: Chemical Characteristics, Peat, Drainage.

Abstract

Untuk mempercepat tersedianya unsur hara dalam budidaya tanaman, masyarakat pada umumnya melakukan sistem tebas bakar. Lahan yang dibakar itu selain areal pertanian, juga berada di kawasan perkebunan, dan sangat berdampak terhadap berbagai gatra kehidupan. Pemulihan tanaman hutan setelah kebakaran akan memakan waktu lama, dan akan sering terhambat bila kebakaran terulang. Kerusakan ekosistem akibat kebakaran berpeluang melenyapkan aneka jenis makro dan mikro organisme tanah, khususnya yang tidak mampu menghadapi perubahan keadaan huniannya serta berbagai jenis organisme tanah yang berpotensi dalam kesuburan tanah. Selain itu mikroorganisme tanah yang banyak berasosiasi dengan tanaman yang hilang akibat kebakaran juga akan ikut hilang, sehingga keanekaragaman dari jenis mikroorganisme juga dapat berpotensi semakin berkurang. Mengingat pentingnya peran mikroorganisme tanah khususnya fungi, dalam proses dekomposisi bahan organik pada tanah gambut dan masih relatif terbatasnya informasi mengenai jenis fungi pada tanah gambut, perlu mempelajari biodiversitas fungi tanah gambut dalam rangka mempercepat proses dekomposisi bahan organik. Tujuan dilaksanakannya penelitian ini adalah Untuk mempelajari biodiversitas fungi yang terdapat pada lahan gambut yang tidak terbakar dan setelah kebakaran, mengetahui fungi pada tingkat kedalaman gambut pada pada lahan gambut yang tidak terbakar dan setelah kebakaran dan mengetahui hubungan antara biodiversitas fungi dengan faktor fisik dan kimia tanah pada lahan gambut yang tidak terbakar dan setelah kebakaran. Hasil penelitian menunjukkan bahwa sehabis kebakaran kegiatan dan jumlah mikroorganisme tanah meningkat yang di tunjukkan pada tanah gambut tidak terbakar, fungi yang teridentifikasi sebanyak lima jenis yaitu Aspergillus niger, Penicillium, Phytopthora, Thielaviopsis dan Thrichoderma harzianum sedangkan pada tanah gambut setelah kebakaran fungi yang teridentifikasi sebanyak Sembilan jenis yaitu Acremonium, Aspergillus niger, Candida, Curvularia, Penicillium, Phytium, Phytoptora, Thielaviopsis dan Thrichoderma harzianum. Hal ini tidak lepas dari beberapa faktor lingkungan tanah gambut seperti kedalaman muka air tanah, tingkat kematangan tanah gambut, suhu tanah gambut, kadar air tanah gambut, bobot isi tanah gambut dan pH tanah gambut pada lahan yang tidak terbakar ataupun yang telah mengalami kebakaran.

Abstract

Questioning skills is one of the basic skills taught are important to master teachers. Lack of good questioning skills possessed by teachers can lead students in an attention too. This study aimed to describe the questioning skills junior high school teacher in mathematics. This study used a qualitative approach with descriptive research. Subjects in this study are two mathematics teachers from two different schools: one teacher MTsN Matangglumpangdua and one teacher SMP N 5 Peusangan. Qualitative data analysis performed on both the teacher to see the questioning skills of teachers in learning. In general, teachers questioning skills include aspects of pausing, prompting and probing in mathematics has been done, but not all of the indicators on each aspect met for each meeting in both schools. In a study in MTsN during two meetings, at the prompting aspect is not done once the indicator solve the question into several sub-questions of the original question and the probing aspects of displacement indicators do not turn. Furthermore, in a study in junior high school for two meetings, on aspects prompting two indicators do not solve the question into several sub-questions of the original question and review (repeat) information previously provided.

Abstract

Setiap atlet yang akan menghadapi suatu pertandingan dalam berbagai even pertandingan, dalam keadaan cemas karena berbagai tekanan yang menjadi beban bagi dirinya. Kecemasan berdasarkan pengelompokannya ada kecemasan bawaan, dan ada juga kecemasaan yang sesaat. Kecemasaan bawaan lebih mendapatkan penanganan yang agak sulit karena sudah bawaan, sedangkan kecemasan sesaat dapat dilakukan dengan berbagai penanganan yang lebih mudah dibandingkan kecemasaan bawaan. Kecemasan sesaat masih dikelompokkan lagi dalam kecemasan cognitive dan kecemasan somatic. Banyak hasil penelitian mengungkapkan kecemasan somatic yang banyak cenderung berpengaruh pada atlet ketika menjelang pertandingan dibandingkan dengan kecemasan kognitif.

Abstract

Background: Salam leaves (Eugenia polyantha Wight) contains antioxidant compounds, flavonoids and polyphenols. These compounds are reported to inhibit oxidation activity by binding with free radicals. The unlimited amount of free radicals in the body will increase the risk of contracting degenerative diseases.Objective: The purpose of this study was to identify compounds from the ethanol extract of salam leaves and to test the antioxidant activity of its compounds using DPPH method and also determine the IC50 (Inhibition Concentration 50) of between the ethanol extract of salam leaves and quercetin standard. Methods: Ethanol concentration extract of salam leaves were obtained by maceration method with the ethanol solution. The compounds were identified by phytochemical screening. The concentration used for the extraction of salam leaves were 30%, 40% and 50%. The variations of each extract concentration were 50, 75, 100, 125 and 150 mg/mL. The variations of standard quercetin concentration were 1, 2, 3, 4 and 5 mg/mL. Antioxidant activity was tested by visible spectrophotometry using the DPPH method. The antioxidant activity is represented as the per cent of free radical scavenging and IC50. Results: The 30%, 40% and 50% ethanol extract of salam leaves contained flavonoid and polyphenol compounds, and also had free radical binding activity. The average value of IC50 quercetin, 30%, 40% and 50% ethanolic extract of salam leaves were 1.68, 102.48, 149.88 and 197.19 mg/mL.Conclusion: Statistical analysis showed that the antioxidant activity between quercetin, 30%, 40% and 50% ethanol extract of salam leaves were significantly different (P=95%).
