Abstract

Municipal solid waste and agricultural waste have different ratio C/N and nutrients contents. They can be used as compost row materials. The purpose of the research was to get an optimum combination of both wastes to improve compost quality, to meet the Indonesian National Standard 19-7030-2004. Composting process use pots. The treatments were twelve combination of municipal solid waste (garbage market, household waste, restaurant waste) and agricultural waste (rice straw, empty fruit bunches of oil palm, cassava peel, banana skin) with a ratio of 1:1 and enriche by chicken manure, cow manure, wood ash and cellulolytic microorganisme. The treatment were replicated three times. The results showd that the nutrients content of compost were 0.77 to 1.19% nitrogen,  0.23 to 0.30% phosphorus, 0.46 to 0.69% potassium and 15.48 to 34.69% organic matter. The combination of agricultural waste and municipal solid waste affected the quality of compost. Compost that meets SNI 19-7030-2004 is a combination of rice straw+market waste that contains 1.12% nitrogen, 0.28% phosphorus, 0.63% potassium, ratio C/N 19.50, pH 7.42, and organic matters 37.65%.

Abstract

White oyster mushroom (Pleurotus ostreatus) requires a source of nutrients for growth and development. The provision of NPK fertilizer aims to increase the source of media nutrients so that the results obtained are better in quantity and quality. Growth regulators can stimulate the relatively long growth of oyster mushroom mycelium. Growth regulators contain hormones that can support growth rates. One alternative natural growth regulator that can be used is coconut water. The research was carried out at the oyster mushroom kumbung at Pekanbaru, using a completely randomized design, consisting of 2 factors and three replications. The first factor was NPK fertilizer consisting of 4 levels (0, 7.5, 10, 12.5) g per baglog. The second factor was coconut water consisting of 4 levels (0, 3, 6, 9) ml per baglog. Data were analyzed using Analysis of Variance and further tested using DNMRT level 5%. The results showed that adding 10 g of NPK fertilizer and 6 ml of coconut water per baglog was a better dose for the number of fruit bodies, fresh fruit body weight, fruit cap diameter, fruit stalk length, and biological efficiency.

Abstract

The aim of the research was to find out potential strainsof cellulolytic bacteria isolated from two tropical peat soils and to studythe potency of the isolated bacteria to decompose oil palm empty fruit bunch (EFB). The research was carried out in two stages: (1) isolation of cellulolytic bacteria from peat soils and (2) testing the potency of isolated bacteria to decompose oil palm EFB. The cellulolytic bacteria were isolated from two peat soils, i.e. a natural peat soil (forest) and a cultivated peat soil (has been used as agriculture land). Isolation of cellulolytic bacteria was conducted by preparing a series dilution of culture solutions using a streak plate method in a carboxymethyl cellulose(CMC) selective medium.Isolates that were able to form clear zones surrounding their bacterial colony were further tested to study the potency of the isolates to decompose cellulose in oil palm EFB. The cellulolytic activity of the selected isolates were further determined via production of reducing sugars in an oil palm EFB liquid medium using Nelson-Somogyi method. The results showed that there are six isolates of cellulolytic bacteria that have been identified in two tropical peat soils used in the current study. Two isolates are identified in a natural peat soil (forest) and four isolates are identified in a cultivated peat soil. The isolates collected are identified as Bacillus sp., Pseudomonassp. and Staphylococcus sp. Among the isolates, an isolate of GS II-1 produces the highest concentration of reducing sugars, namely 0.1012 unitmL-1or 101 ppm, indicating that the isolate of GS II-1 is highly potential to decompose oil palm EFB. Therefore, the isolate of GS II-1 can be used as a decomposer in the bio-conversion processes of oil palm EFB.Keywords: isolation, bacteria, cellulolytic, oil palm empty fruit bunch (EFB), peat soil

Abstract

Onion productivity in Riau was reached 6.1 ton/ha, whereas Indonesian onion productivity has reached 12.3ton/ha, and potential productivity of onions is 14.4 ton/ha. This less onions productivity in Riau is mainlycaused by environmental factors such as climate, the lack of mulch or fertilized calcium. Therefore, toincrease onion productivity in Riau we can use some types of mulch and calcium applying together. A goal ofthis experiment is to increase Riau onion productivity. This experiment had done in the farm of the.AgriculmreFaculty, Riau University in October to December 2003. The experiment was designed with CompletelyRandomized Design in factorial, and the treatment combinations were replicated three times. These factorswere types of mulch in the levels: Without mulch (m,), Grass mulch (nij), Transparence Plastic Mulch (ra,),Black and Silver Plastic Mulch (m^), and doses of Calcium fertilizer in the levels: Without Calcium (K„) and234 lig KCl/ha (K,). The response variables were: sum of slices in each plant, manure weight of the plant perplot (g), dry weight of the plant per plot (g), diameter of hiber (mm), and consumer product per plot (g).Resultsof the experiment showed that there is no interaction between the types of mulch and doses of Catciiun C 'U/hiU-fertilizer in the response variables. The effect of tlic treahncnt combinations could be observed by the types ofmulch only. Black and Silver Plastic Mulch increased the productivity to 9.S ton/ha. This treatment couldincrease manure weight of the plant per plot about llM.6%,dry weight of plan per plot 117.4%, diameter oftuber 27.8%, and consumer product per plot T20,l % when compared to onion without mulch.

Abstract

Oil palm empty fruit bunches (OPEFB) is one of the largest types of solid waste produced by palm oil mills (POM). Each processing of 1 ton of fresh fruit bunches (FFB) produces 220–230 kg of empty fruit bunches (EFB). One of the attempts to overcome the accumulation of EFB is by composting. The main obstacle in composting OPEFB is the process of overhauling, it takes 6-12 months because OPEFB contains 33.02% cellulose, 22.05% hemicellulose and 35.08% lignin. One of the efforts to speed up the composting is using biological treatment by adding microorganisms such as cellulolytic bacteria which are capable in producing cellulase enzymes. The reseach was carried out experimentally using a non-factorial completely randomized design (CRD) consisting of eight treatments, namely B0 (control), B (Bacillus tequilensis Strain RA 1402), B2 (Bacillus subtilis Strain C17), B3 (Bacillus subtilis Strain SKUASIS) , B4 (Bacillus subtilis Strain DSM 10), B5 (Bacillus subtilis Strain K43), B6 (Pseudomonas aeruginosa Strain KUJM) and B7 (Combined Isolates). The parameters observed were physical properties of compost, weight loss of compost and total of compost microb population. The resultof the research showed that cellulolytic bacteria isolates had a significant effect on weight loss of compost, pH. The combined isolates (B7) is the best treatment in increasing compost material weight, pH. The treatment B7 has the best ability in producing high quality compost which is under the SNI Compost Quality Standard: 19−7030−2004.

Abstract

One of the efforts to increase rice production in the dry land of ultisol such as in Riau is extensification. To alter low nutrient availability in ultisol, liquid organic fertilizer (LOF) from waste of banana corm and NPK fertilizers are evaluated. Research aimed to obtain the best dose of LOF and NPK fertilizers to improve the productivity of upland rice on ultisols. This experiment was arranged in a completely randomized factorial design consisting of two factors. The first factor was LOF from banana corm (0 mL, 50 mL, 100 mL, and 150 mL per polybag). The second factor was NPK fertilizers (0%, 25%, 50%, and 100% recommendation dose); the recommendation base was: 300 kg Urea, 100 kg TSP, and 100 kg KCl ha-1. The results indicated that the application of 150 mL LOF per polybag and NPK fertilizers at 100% recommendation significantly enhances plant height, number of tiller numbers, productive tiller, filled grain per panicle, and dry grain weight of Inpago 9 variety.
