Abstract

Pemanfaatan tanah lahan gambut sebagai kompos belum banyak dilakukan. Penelitian pendahuluan mengenai hal tersebut dilakukan dengan mengkomposkan tanah lahan gambut dengan bantuan A. niger dan stimulator EM4. Kemudian diujikan kepada tanaman jagung. Hasil penelitian menunjukkan bahwa kompos tanah gambut terbaik diperoleh dari perlakuan penambahan spora A. niger sebanyak 15 ml dengan lama pengomposan 3 minggu. Kompos tersebut memiliki kadar rasio C/N terendah dibandingkan perlakuan lain yaitu 0.46% dan kadar P total sebesar 195 ppm. Rata-rata berat kering akar, batang, daun serta pipilan jagung memiliki pola yang relatif sama, mengalami kenaikan pada pemberian kompos tanah gambut dengan penambahan spora A. niger 7.5 ml dengan lama pengomposan 1 minggu, yaitu berturut-turut 1.2gr, 0.7gr, 3.5gr dan 0.11gr. Kompos tanah gambut hanya memberikan pengaruh yang nyata pada berat kering daun. Berat kering daun tertinggi (3.5 gr) diperoleh dari pemberian kompos tanah gambut dengan penambahan spora A. niger 7.5 ml, pengomposan 1 minggu.

Abstract

 Lotus, classified as Nymphaea, is hydrophyte plant with high potencies. The aim of the study is to discover the utilization and processing of lotus plant, and to determine the secondary metabolite of Nymphaea pubescens Willd. and N. nouchali Brum F. The methods used were by doing survey and direct interview with semi-structural technic by fulfilling questionnaire data. Selection of respondents was done by simple random sampling method. Sample taking was done by purposive sampling which considered the sample existence that could represent those lotus plants. The results showed that the utilization of N. pubescens is mostly around 47% by boiling, pounding, and sauteing them meanwhile the utilization of N. nouchali Brum F is mostly around 73% by boiling and sauteing them. Parts of the lotus plant used are seed and stem. Leaves of N. pubescens are used for healing dysentery by making them for drink. Seeds of N. pubescens have potencies in increasing functions of heart and lymph, improving stamina, anti-aging, curing diarrhea, and desentery.

Abstract

The research was aimed to reveal the effect of fructose consentration on the motility and viability time of carp’s spermatozoa, and to determine the optimal consentration of fructose. A completely randomized design was applied with 0.5%, 1%, 1.5%, 2%, 2.5%, 3%, 3.5%, and 4% fructose concentrations. Undiluted semen and aquades-diluted semen were used as controls. Fast progressive and slow progressive motility of spermatozoa were recorded as well as the viability time (in minutes) of the spermatozoa.   The results showed significant difference in motility and viability time of spermatozoa with different concentrations of fructose. The optimal average concentration was 3%, resulting in fast progressive motility of 11 seconds, slow progressive motility of 165 seconds, and viability time of 4 hours 46 minutes. The increase in motility and viability time were assumed to be related to the use of  fructose as energy source and nutrition for spermatozoa.

Abstract

This research to study antibacterial activity (E.coli and S.aureus) of saponin fractions from stem bark of Mangifera casturi. Powdered of stem bark of M.casturi (512,67 g) were extracted with methanol. Methanol extract (32.57 g) was partitionated with n-hexane to give saponin extract. Saponin extract (5.98 g) was partitionated by Vacuum Liquid Chromatography (VLC) over silica gel to give 39 fractions were grouped into four major fractions A-D by combining fractions with similar TLC profile. Every fractions studied antibacterial activity with E. coli and S. Aureus with difusi methode. Fraction A most active then other fraction with inhibition diameter 10.3 ± 0.5 mm (E.coli) and 10.8 ± 0.3 mm (S.aureus).

Abstract

Sejak adanya pertanian menetap, usaha perlindungan tanaman telah dikenal. Adanya organisme pengganggu tanaman, khususnya serangga menyebabkan kerugian yang cukup tinggi. Penggunaan pestisida untuk memberantas pengganggu tertentu malah berakibat resurgensi, resistensi, musnahnya musuh alami, serta pencemaran lingkungan.  Salah satu teknik augmentasi adalah perlindungan yang memberikan gulma sintetis sebagai habitat pengganti untuk serangga predator, dengan tujuan untuk memberikan musuh alami bagi pengganggu.  Tujuan penelitian ini adalah untuk mengetahui preferensi serangga familia Coccinelidae untuk memilih kombinasi tanaman familia Asteraceae dan waktu orientasinya. Dalam penelitian ini digunakan olfaktometer. Serangga uji diaklimasi selama 24 jam, dengan replikasi dua puluh kali. Waktu yang dibutuhkan serangga untuk memilik keempat kombinasi tanaman dicatat. Digunakan analisis deskriptif.   Hasil penelitian menunjukkan bahwa Coccinella septempunctata tertarik kepada Eupatorium odoratum dengan persentase ketertarikan sebesar 50% dan waktu orientasinya 419 detik. Synharmonia conglobata 35 % lebih tertarik pada kombinasi tanaman Bidens pilosa dan Crassocephalu crepidiodes dengan waktu orientasi rata-rata 457 detik.

Abstract

Grayak caterpillar is a pest that always attacks the crops of horticultural and vegetables in Indonesia every growing season that causes farmers to experience crop failure. Kepayang plants contains some secondary metabolite compounds including high glycocyanide acid in each part of the plant. The purpose of this study was to determine the effect and optimal dosage of kepayang leaf extract as a vegetable pesticide on grayak caterpillar mortality. This research used Non-Factorial Randomized Complete Random Design (RCRD) with four treatments in two observation times and each treatment there were three replications. The extraction was done by maceration method using aceton p.a and thickened using rotary evaporator. Mustard as grayak caterpillar feed is dipped in kepayang leaf extract with three dose levels of 1.5gr / L, 1.75gr / L, and 2gr / L is observed for 72 hours and 96 hours. The results showed that pepper leaf extract had an effect on mortality of grayak caterpillar. Variant dose of pepper leaf extract (1.5gr / L, 1.75gr / L, and 2gr / L) in this study have the same cidal effect on grayak caterpillar.

Abstract

To optimalize the existence of natural enemies, it is necessary to provide some plants as microhabitat, alternative foods, place for perching, mating and shelter. This research was done to know the most attractive plant of Mimosaceae (Mimosa pigra and Mimosa pudica) and Papillionaceae (Centrosema pubescens and Crotalaria retusa) for Scaeva pyrastri. In addition, the research can be used to find out the combination of those plants which are examined using olfactometer based on the volatile chemicals released by the plants. Scaeva pyrastri, member of the family Syrphidae, was captured from field. Then, it is aclimazed for 24 hours in laboratory. Fours plants about 21 grams of biomassa are put in the four glass boxes. The insect, Scaeva pyrastri, was put in the centre of olfactometer connected to the glass boxes by the odours arms. The orientation collected from 30 multiplication was analized statistical descriptively. For single test, Scaeva pyrastri was highly attracted to Centrosema pubescens and the orientation time needed was about 1 minute 23 second. For combination test, the most atraccting plant was Centrosema pubescens and the orientation time needed was about 1 minute 15 seconds.
