Abstract

ABSTRAK. Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian campuran abu terbang-kotoran ayam (ATB-KA) terhadap perubahan titik muatan nol (TMN) tanah dan dampaknya terhadap jerapan dan ketersediaan P pada Ultisol. Dua perlakuan yang diuji adalah ATB-KA (w/w 1:1) pada dosis 0, 15, 30, 45 dan 60 ton ha-1, dan pemupukan P pada dosis 0, 87, 174, 261 dan 348 kg P2O5 ha-1.  Perlakuan ini ditata dalam Rancangan Acak Lengkap yang diulang sebanyak tiga kali. Hasil penelitian menunjukkan bahwa aplikasi CATK untuk setiap dosis pemupukan P berkorelasi secara nyata dengan status tanah TMN, pH, muatan negatif, jerapan dan ketersediaan P. TMN berkorelasi positif dengan pH dan muatan negatif. Muatan negatif secara nyata berkorelasi negatif dengan jerapan P, dan berkorelasi positif dengan P tersedia. Modification of PZS of Soil With Variable Charge by Application of Coal Fly Ash-Chicken Manure MixtureABSTRACT. The objective of current research was to study the effect of coal fly ash-chicken manure mixture (FA-CM) on the changes on the soil PZC status and its impact on P sorption and availability in Ultisols. Two treatments - FA-CM mixture (w/w of 1:1) at the rate of 0, 15, 30, 45 and 60 ton ha-1, and P fertilization at the rate of 0, 87, 174, 261 and 348 kg P2O5 ha-1 were tested.  These treatments were arranged according to Factorial Completely Random Design with three replicates. The results showed that the application of FA-CM for each dosages of P fertilizer correlated significantly with the status of soils PZC, pH, negative charge, P sorption and P-available. PZC has possitive correlation with pH and negative charge. Negative charge has a significantly negative correlation with P sorption, and posssitively correlation with P-available.

Abstract

ABSTRACT Snakehead fish is one of swamp fish species that has not been successfully cultivated intensively, therefore it is necessary to do a particular effort for rearing snakehead fish. Rearing of fry snakehead fish in the swamp water media by modifiying pH is expected to be able to support the survival rate and growth.The research uses CDR with 5 treatments and 3 replications. Modification of water pH will be done by adding HCl or NaOH. Increasing or decreasing pH will be conducted continuosly for 30 days. The result of this research showed that continues modification of rearing media pH is very significantly affected survival rate of fry snakehead fish with P3 (decreasing from pH 5.75 to pH 5.00) as the best treatment. This treatment gave survival rate of 67.90% and weight biomass of 9.8982 grams Keywords : Fry snakehead fish, pH, swamp water, survival rate and growth

Abstract

ABSTRACT The purposes of this research were to increase vitality of white shrimp postlarvae during adaptation time to salinity decrease with the addition of papaya juice, and to assess the physical and chemical properties of water during their adaptation. The research was conducted in October 2011 at the Laboratory of Aquaculture, Aquaculture Study Program, Faculty of Agriculture, Sriwijaya University.  The research used a completely randomized design in order to evaluate the effect of a various papaya juice concentration. The concentrations used were without papaya juice addition (P0), addition of papaya juice equivalent to 15 ppm K+ (P1), addition of papaya juice equivalent to 30 ppm K+ (P2), addition of papaya juice equivalent to 45 ppm K+ (P3), and addition of papaya juice equivalent to 60 ppm K+ (P4). Each treatment was repeated 3 times. The results of this current study showed that the addition of papaya juice equivalent to 15 ppm (P1) in media that used to decrease salinity was concluded as the best treatment, and gave the survival rate of 65.56%, glucose level of 156.67 mg.dL-1 and oxygen consumption rate of 4.807 mg O2.g-1.hour-1. The physicsal and chemical properties of media used for adaptation were still within a tolerable range for white shrimp postlarvae, except pH tent to be lower than the criteria.   Keywords : vitality, papaya, white shrimp, adaptation, salinity
