Error analysis on students’ essay writing: A case study

The objective of this research is to determine the types of errors committed by the students of the English Department at the Faculty of Language and Science, Wijaya Kusuma Surabaya University (FBS UWKS), as well as to describe the origins of these errors. The research conducted was descriptive in nature, utilizing qualitative methods. The participants involved in the study were fourth semester students of the English Department at FBS UWKS. Out of the 20 participants, a total of 80 data sources were obtained during the learning process. The researchers collected the data through the use of interview sheets and essays. Once collected, the data underwent a process of reduction, classification, display, and analysis. The procedures for data analysis were outlined as follows: 1) the collection of essays, 2) the classification, counting, and analysis of errors based on the error types proposed by Brown (2007), and 3) the analysis of errors to identify their sources using the concepts of interlingual transfer and intralingual transfer as proposed by Brown (2007) and Touchie (1986). From the analysis, it was discovered that the errors could be categorized into two main groups, namely essay organization errors and grammatical errors. The essay organization errors consisted of seven classifications, including issues with the thesis statement, topic sentences, unity, coherence and cohesion, as well as supporting sentences. On the other hand, the grammatical errors encompassed omission, addition, and punctuation mistakes. The sources of these errors were found to be inadequate learning, false conceptualizations, overgeneralization, and ineffective teaching practices.

Potensi Alellopati Ekstrak Gulma Alang Alang Sebagai Bioherbisida

The aim of this study was to determine the Alellopathy Potential contained in Imperata cylindrica extract as a Bio-herbicide. The research was conducted at the Experimental Garden of the Faculty of Agriculture; Wijaya Kusuma Surabaya University. This research method used completely randomized design (CRD); with 4 treatments and 6 replications. The treatments are (A0): Control; A1 : extract concentration ( 250 g/L) ; A2 : 500g/L ; (A3); 750 g / L. Observational data were analyzed using Analysis of Variant (ANOVA), then tested with 5% BNT. The results showed allelopathy contained in the extract of Imperata cylindrica L. can suppress weed seed germination up to 94.67 %; and has a negative effect on the initial growth of spiny spinach (Amaranthus spinosus L) seedling sprouts. With treatment A2 and A3 ; All weed seeds that were able to germinate grew abnormally (100%). Imperata cylindica extract has the potential to be used as a bio-herbicide (natural herbicide) to suppress the early growth of weed seeds on spinach spines.

CHARACTERISTICS AND FIGURES OF FRESH TILAPIA BACTERIA FROM TAMBAK SAWIYOH SIDOARJO

ABSTRACTThis study aims to analyze characteristic and calculate the number of bacterial contamination of fresh nila fish from Sawiyoh pond Sidoarjo, East Java. A total of 30 fresh nila fish were taken and examined at the Microbiology Laboratory Faculty of Medicine Wijaya Kusuma Surabaya University. This research is a descriptive study with observational methods. The step of bacterial enrichment was carried out on BPW (Buffered Pepton Water) media. The bacterial identification procedure uses selective media SSA (Salmonella-Shigella Agar), Gram staining, and tests on TSIA media (Triple Sugar Iron Agar). The procedure for calculating the total bacteria using TPC (Total Plate Count) on NA (Nutrient Agar) media. The results on selective SSA media in 30 samples showed suspect Salmonella sp. with the characteristics of colorless colonies with black dots in the middle. The results of Gram staining in 30 samples showed that the bacteria were Gram negative in the form of rods. Test results on TSIA media identified one positive sample of Salmonella sp. (sample 09) with characteristics of the red slope of the media, the base of the media is yellow, and H2S is formed. The results of the calculation of total bacteria by the TPC method showed that the total bacterial total was 15.8 x 105 CFU / gram. The limit of microbial contamination according to the 2009 SNI for fresh fish is 5 x 105 CFU / gram so that fresh nila fish from Sawiyoh Sidoarjo pond has a number of bacterial contamination above the stipulated threshold.Keywords: Nila Fish, Gram Staining, Salmonella sp., Salmonella-Shigella Agar, Total Plate Count, Triple Sugar Iron Agar

PERSEPSI MAHASISWA FAKULTAS EKONOMI MENGENAI PENGGELAPAN PAJAK (STUDI PADA MAHASISWA FAKULTAS EKONOMI UNIVERSITAS WIJAYA KUSUMA SURABAYA)

Tax evasion is a tax deductible scheme that is owed by violating the provisions of taxation (illegal). Tax evasion is usually done by the company by making false invoices, not recording some sales, or preparing fake financial statements, but the practice of tax evasion like this is often caught, thus the mode of tax evasion is now changing. Perception is the response of something or is the process of knowing some things through the senses. This research is interested to prove the perception of the students of economics faculty regarding the tax evasion, where these students have received taxation class and practice. This study uses questionnaires to obtain students perception data, and use purposive sampling in obtaining sample research. Data analysis technique used is multiple-linear regression. The result of research shows that only discrimination variables affect the tax evasion based on the perception of the students of economics faculty, while the variables of justice, taxation system and understanding of taxation do not affect tax evasion based on the perception of the students of Economics Faculty, Wijaya Kusuma Surabaya University.
