Abstract

Penelitian ini bertujuan untuk isolasi dan seleksi  fungi limbah industri  kayu putih. Limbah penyulingan daun kayu putih selama ini belum dimafaatkan untuk pupuk organik karena  sulit didekomposisi akibat kadar selulosa yang tinggi.  Disisi lain limbah ini memiliki potensi yang besar untuk dikembangkan sebagai bahan baku pupuk organik. Oleh sebab itu perlu dicari fungi yang memiliki kemampuan untuk menguraikan limbah tersebut. Fungi dapat mengekskresi enzim selulase yang berfungsi mendegradasi selulosa.  Sampel limbah diambil secara random  sampling di 3 tempat dilimbah pabrik kayu putih.   Fungi dikembangkan pada  media cair, kemudian diisolasi  dan diidentifikasi pada media padat. Hasil penelitian menunjukkan bahwa ditemukan 3 isolat fungi yang ada di limbah industri kayu putih dan yang mempunyai potensi untuk agen decomposer hanya 2 isolat yaitu aspergilus niger dan trichoderma viride.

Abstract

Soybean is one of the food commodities, which contains vegetable protein, carbohydrates and fat, hence it is necessary to complement the nutrition. Demand consumption of soybean higher with increasing population annually, the production of soybean is still sufficient to complete the increasing of demand. Therefore, the increasing of soybean production has to be considered to decrease the dependency on imported. Soybean production can be increased by the cultivation technique. In this method, the present of weed should be concerned. Weed can reduce the quality and quantity of soybean. The research was done at Kebun Pendidikan, Penelitian dan Pengembangan Pertanian (KP4) Gadjah Mada University which located at Kalitirto, Berbah, Sleman, Yogyakarta, Indonesia. This research started on November 2015-April 2016. The research aims to identify the effects of weed on the growth analysis of several soybean cultivar. This field research is arranged using spit plot with three blocks as the repetition where the main-plot is the weed treatments andthose are weed-free, weeding in a critical period, and weedy. Sub plot is the soybean cultivars which are Anjasmoro, Argomulyo, Burangrang, Gema, Gepak Kuning, Kaba, and Wilis. The research’s result show the weed treatments would effect no significant difference in the leaf area index, net assimilation rate, crop growth rate (3 to 6 weeks after planted/WAP), specific leaf weight, and leaf area ratio (3 WAP). Which affects are the crop growth rate (6 to 9 WAP) and leaf area ratio (6 and 9 WAP)

Abstract

The conversion of forest for another purpose has made the population and diversity of medicinal plants increasingly threatened. The ex situ conversion by cultivation is needed to provide the suitable environment to ensure the plants grow in their natural habitat and maintain their properties. One of the traditional medicinal plants in Sanggau Malay which has been believed to neutralize the toxin is “anggrek penawar racun” (Plocoglottis lowii Rcbb.f.). This research was important to be done since there was no data and information about mychorrizal type associated to root of orchid P. lowii Rchb.f. in its natural habitat. The aim of this research was to find out the data and information about the types, the characteristics, and the percentage of mycchorizal fungal infection in root tissue for conservation and cultivation purpose. The research used 10% KOH heating method and freehand section coloring using Trypan Blue, Acid Fushin dan Safranin-O conducted in cross section of the roots. The results showed that there was only one species of fungi and it was identified as Rhizoctonia sp. Binucleate type. The highest percentage of mycchorizal infection  occurred at the tip of the roots (90%). It has been found that the location of mychorrizal infection has occurred between the epidermis and cortex. It is needed to do the further study about mychorrizal isolate Rhizoctonia sp. effectiveness in the growth of P. lowii Rchb.f in the cultivated land.

Abstract

Strawberry (Flagaria chiloensis, L.) is a herbaceous plant thatpropagates, the fruit contains lots of fiber, vitamin C, folic acid, potassium and antioxidant. The research was conducted in the experimental field of the Agriculture Faculty, Gajah Putih University, Blang Bebangka, Pagasing District, Central Aceh Regency with a height of ± 1,150 m above sea level, soilpH 5.5 – 6.0. This research was conducted in February until April 2018. The research used factorial randomized block design (RBD) with two factors. The first factor is organic mulch consisting of 4 levels, (M0) = No mulch (control); (M1) = wood sawdust mulch; (M2) = rice husk mulch; (M3) = waste coffee mulch. The second factor is the ratio of planting media (kg) which consists of 4levels,(T1) = soil, sand, manure (7: 1: 2); (T2) = soil, sand, manure (6: 1: 3); (T3) = soil, sand, manure (4: 2: 4); (T4) = soil, sand, manure (3: 2: 5).The results of this study indicate that wood sawdust mulch produces the average number of tillers (6.25 children) and the best strawberry fruit weight (65.66 g per clump) from organic mulch treatment. Comparison of planting media, soil, sand and manure (3: 2: 5) produces the number of tillers (7.5 tillers) and strawberry fruit weight (76.73 g per clump) which is the best from the comparison treatment of planting media. The combination treatment of comparison of planting media, soil, sand and manure (3: 2: 5) with organic mulch treatment produces the best average number of tillers and strawberry fruit weight from the treatment combination.
