Vegetative growth performance of two varieties of maize by pulp and paper waste application has been studied in peat soils using Factorial Completely Randomized Design in biological garden, faculty of education and teacher training, Riau University. The experiments were arrange by factorial 2 x 5 and three replications. First factor was two maize varieties i.e. Arjuna and Bisi-2. Second factor was Pulp and Paper waste taken from Riau Pulp and Paper Industry. Rate of application were 0, 15, 20, 25, and 30 gr kg 1peat soils. Plant height, leaf length, leaf wide and plant dry weight were measured. Data analyzed by using ANAVA dan Duncan’s Multiple Range Test at 5% level of signification. The results shows that plant height and leaf length has significance difference between two maize varieties, but not for leaf wide and dry weight. There were no significant interactions effects for all parameters observed. We conclude that the varieties of Arjuna more tolerance and adaptive to peat soil.Key words : pulp and paper industrial waste, maize tolerance, vegetative growth

PENGARUH JENIS BAHAN PENGEMAS DAN LAMA PENYIMPANAN TERHADAP KADAR VITAMIN C DAN SUSUT BERAT CABAI RAWIT (Capsicum frutescens L.) Sri Wulandari; Yusnida Bey; Kartini Desyani Tindaon

interactions on levels of vitamin C and weight loss of chili (Capsicum frutescens L.), which is performed at the Laboratory of Biology Education and the Laboratory of Soil Science FKIP Faperta UR on November-December 2011. The research design was randomized block design (RGD) factorial with two factors: package varians and time of storage. The package varians consist of plastic, newsprint, and banana leaves, and the time of storage consist of 0 day (control), 3 days, 6 days and 9 days with three replications. The parameters in this reseach are vitamin C levels, weight loss, color and texture of chili. The levels of vitamin C and weight loss were analyzed by ANAVA and then tested by DMRT 5% level, while the observation of color and texture were analyzed descriptively. The results showed that the interaction of a banana leaf package varians and storage of 3 days have the highest levels of vitamin C is 55,17 mg and the interaction of a newsprint package varians and storage of 9 days showed the highest weight loss is 26,32%. Banana leaves package varians have the highest levels of vitamin C 51,16 mg and the lowest weight loss is 5,95%. 3 days storage time have the highest levels of vitamin C 53,12 mg and the lowest weight loss is 7,84%. The conclusion is the interaction of banana leaf package varians and 3 days time storage gives the best quality of color and texture compared to other treatment interactions. Banana leaves are good for package chili. The increasing of time storage will increase the weight loss, decrease the vitamin C level and the color and texture quality of chili.Keywords : Chili, Levels of vitamin C, Package varians, Time of storage, Weight loss

DAMPAK PEMBERIAN PAKAN PELLET IKAN TERHADAP PERTUMBUHAN KIAPU (Pistia stratiotes, L) Yusnida Bey; Sri Wulandari; Sukatmi '

This research have purposed to know about effect of fish palette to growth Kiapu that conducted in the strands of metal house in Biological education Laboratory FKIP UNRI and PKA Faperika UNRI at June-July 2007. This research is an experiment with complete Random Design (RAL) that includes 4 treatment on the dosis of palette about 0; 4,5; 6 and 7,5 gr/10 L each with 6 time retesting. The parameter have observed included chemical physics of water factor is ammonia, free of CO2, disolved oxygen, pH and temperatur, while biology factor have observed is the growth of kiapu enveloped long of roots, sum up roots, wide of leafs, sum of leafs and sum of seeds. The growth of Kiapu data have analyzed with the ANOVA with the DMRT continued test on 5% of significance. The results of research indicate that gift palette of fish is effecting to water quality (ammonia, free of CO2 and disolved oxygen concentration) affecting also to biology factor of Kiapu is long of roots, sum up roots, sum up leafs and sum up seeds except wide leafs. On the A2 (6 gr/10 L) is effective for increasing sum up roots, sum up leafs and sum up seeds.

PENGARUH PEMBERIAN GIBERELIN PADA MEDIA VACIN DAN WENT TERHADAP PERKECAMBAHAN BIJI ANGGERIK BULAN (Phalaenopsis amabilis Bl) SECARA IN VITRO Yusnida Bey; Wan Syafii; Nur Ngafifah

In vitro investigation has conducted in order to find out the respons of orchid (Phalaenopsis amabilis BI) in Vacin and Went media by Gibberellins treatment, this research was carry out at Balai Benih Tanaman Pangan dan Holtikultura Pekanbaru during June until August 2003 by using completely Random Design through 5 treatment and 4 replication. The treatment were Gibberellins (ppm): 0, 2, 4, 6 and 8. The parameter were observed i.e ; the emergence timing of protocorm like bodies, seedling height, and seedling biomass. Observated data were analyzed descriptifely and analysis of variance with Duncan Multiple Range Test at 5% level of significance. The results shows that the 2 ppm GA3 treatment have a good effect on the emergence timing of protocorm like bodies (13-16 days after planting), average of seedling height (1,5 cm) and seedling biomass (1,18 gr). We concluded that the timing of orchid seedling emergence could be accelerated by increasing the concentration GA3 treatment until 2 ppm. Key words: Seed of orchid, Gibberellins, In vitro, Germination, Phalaenopsis amabilis Bl
