Abstract

Suwandi et al. 2012. Application of Extract Compost Increased Yield and Suppressed the Diseases of Ratoon Rice Crop in Tidal Swamp of Banyuasin Regency. JLSO 1(2):116-122.A field study was conducted to test the effects of the biofertilizer preparations on yield and diseases of ratoon rice crop in the reclaimed tidal swamp of Telang II, Banyuasin Regency of South Sumatra. The biofertilizer were prepared either as dormant inoculant in liquid formulation or active inoculant in compost extract. Both preparations contain chitinolytic, cellulolytic and phosphate solubilizing bacterial community. The result showed that the yield of ratoon crops of Ciherang rice variety in the suboptimal land increased by 67% (923 kg/Ha) in response to single spraying of the compost extract. The ratoon sprayed with the compost extract had a lower incidence of neck blast and panicle blight and produced less empty grains compared to non-sprayed control. The application of extract compost appears to be a feasible method for increasing production of ratoon rice in tidal swamps.

Abstract

The purpose of this research is to analyze Influence of Fairness, Tax System, Discrimination, Possibility of Fraud Detected, and Intensity of Tax Audit on the perception of tax payer on the ethics of tax evasion. The sample consists of 100taxpayers listed in the Tax Office of Pratama Bangkinang. The data that was used in this research was primary data and selected by using accidental sampling method, while the data processing methods used by research are the multiple regression analysis use SPSS version 22.00 as the software for processing the data.The result of the adjusted R-square showed that the value of the adjusted Rsquare is 0,721, which mean that 72.1% the ethics of tax evasion can be explain by the variation of the independent variables, while the other 27,9% explained by other variables which not included in this research. Results of hypothesis testing showed,the result indicate that fairness has affected the perception of taxpayer on the ethics of tax evasion. Tax system has affected the ethics of tax evasion, discrimination has affected the ethics of tax evasion, possibility of fraud detected has affected the ethics of tax evasion, and intensity of tax audit has affected the ethics of tax evasion.Keyword: fairness, tax,discrimination, fraud, and audit

Abstract

Susilawati et al, 2019.The Effect of Using Growing Media Composition on Growth and Yield of Shallot (Allium cepa L.). pp. 93-102.The aimed of research was to study the effect of using growing media composition on growth and yield of shallot (Allium cepa L.). Research was conducted from February until April 2017. Design used in this study was randomized block design (RBD) with 9 treatments and 3 replications. The treatments was A0 = Control (90% soil : 10% chicken manure), A1 = 80% soil : 20% cow manure, A2 : 70% soil : 30% cow manure, A3 = 60%  soil : 40% cow manure, A4 = 50% soil : 50% cow manure , A5 = 80% soil : 20% husk charcoal, A6 = 70% soil : 30% husk charcoal, A7 = 60% soil : 40%  husk charcoal, A8 = 50% soil : 50 husk charcoal. The results showed that the use of planting media composition of 60% soil : 40% of cow manure can improve the growth and yield of shallot plants better. This is consistent with plant height variables, number of leaves, number of tillers, number of tubers, fresh weight of tubers, and dry weight of tubers. The highest dry weight yield was found in the composition of 60% soil : 40% of cow manure with an average yield of 84.36 g per hill.

Abstract

Susilawati et al, 2017. The Growth and Yield of Cauliflowers (Brassica oleraceae var. Botrytis L.) on Planted Media of Aquatic Weeds Compost. JLSO 6(1):43-48.The objective of this research was to know the growth and yield of cauliflowers on various planted media organic of compost aquatic weeds. This research was conducted from November 2016 to Febuary 2017. The research was rendomized block design with ten treatments and three replications.  Each unit consisted of 3 plants, so there were 90 plants.  The treatments were B0: (soil 100%), Be1 (75% soil: 25% water hyacinth fertilizer), Be2 (50% soil: 50% water hyacinth fertilizer), Be3 (25% soil: 75% water hyacinth fertilizer), Bu1 (75% soil: 25% hymenachne compost), Bu2 (50% soil: 50% hymenachne compost), Bu3 (25% soil: 75% hymenachne compost), Bi1 (75% soil: 25% salvinia compost), Bi2 (50% soil: 50% salvinia compost), Bi3 (25% soil: 75% salvinia compost). The result showed that the treatment 75% soil and 25% salvinia compost gave the best effects on weight flowers, leaf number, weight of fresh roots and weight of dry roots.
