Therefore, this study aims to identify the presence of formalin and borax in tuna on the market Ngemplak, Tulungagung regency. The samples used in this study were fresh tuna in the Ngemplak market originating from the beaches of Prigi, Sine, Tambakrejo, Popoh and Sidem. The samples were tested qualitatively using the colorimetric method by Schryver reagent for formalin and curcumin paper for borax. The results obtained in this study, from the five tuna samples not detected contained formalin and borax which were marked by no change in color in the test. Tuna sold in the Ngemplak market Tulungagung regency negatively contains formalin and borax, making it safe for consumption. It is hoped that the relevant office will carry out routine checks on the misuse of food additives, especially preservatives circulating in the community and the public should always be careful in choosing safe food.</p> Qurrotu A’yunin Lathifah Dora Dayu Rahma Turista Ludfiana Azizah Ahmad Erfan Khulaifi Copyright (c) 2019 Medical Laboratory Analysis and Sciences Journal 2019-05-01 2019-05-01 1 1 1 5 10.35584/melysa.v1i1.15 Analysis of bulk oil in Tulungagung district on physical and chemical properties <p>This study aims to analyze the quality of Bulk frying oil in the Tulungagung district. Four samples were a test using physical parameters, organoleptic, density, and viscosity, while the chemical parameters were a test or the value of free fatty acids, acid numbers, and peroxide numbers. Comparison of the results of the analysis with SNI (Indonesian Standard Oil Quality), the four samples have poor chemical properties quality, it could be known by the acid number of samples 0.56, 0.78, 0.78, 1.65 (%) and Free fatty acids number 2.86, 9.98, 4.23, 6.7 (%) are higher than SNI 0.3 and 0.6 (%), even sample D has a poor peroxide number. So that overall, it is shown that the quality of Bulk oil from the samples used is not good enough.</p> Taufik Salis Syaifudin Rizqi Asri Fauzi Nugraha Indra Lasmana Tarigan Copyright (c) 2019 Medical Laboratory Analysis and Sciences Journal 2019-05-01 2019-05-01 1 1 6 12 10.35584/melysa.v1i1.16 Blood calcium levels in factory workers who consume supplements drinks <p>Energy supplement drinks are drinks that contain caffeine, taurine, sweeteners, and other substances that have the effect of increasing energy, concentration, alertness, maintaining physical strength, and reducing drowsiness. Blood calcium is an important mineral that the body needs. The purpose of this study was to determine blood calcium levels in marble factory workers in Besole Village, Tulungagung Regency. The research design used was Analytical Descriptive. The population in this study were all marble factory workers who routinely consumed energy supplement drinks in the village of Besole in 2018 using a total sampling technique of 30 respondents. This research was conducted at the Laboratory of Dr. Iskak Tulungagung in May 2018 using the O-CPC method. The results obtained from the examination of blood calcium in marble factory workers showed 10 respondents (33%) had blood calcium levels within normal limits, 17 respondents (57%) had deep blood calcium levels. low limit and 3 respondents (10%) had very low blood calcium levels. Consumption of energy supplement drinks that exceed the threshold can damage the kidneys and affect blood calcium levels because the caffeine content in energy supplements can increase the release of calcium in the bones so that more calcium is released through the urine.</p> Chalies Diah Pratiwi Hariyanto Hariyanto Amelia Rahma Perdana Putri Copyright (c) 2019 Medical Laboratory Analysis and Sciences Journal 2019-05-01 2019-05-01 1 1 13 18 10.35584/melysa.v1i1.17 The correlation between creatinine serum with total iron binding capacity (TIBC) on patients with sufferers chronic renal disease in Gambiran regional public hospital Kediri city <p>Chronic kidney disease (CKD) is kidney damage that occurs for more than 3 months with a glomerular filtration rate of less than 60 ml/sec/ 1.73 m2. WHO estimates that in Indonesia, there will be an increase in PGK in 1995-2025 by 41.4%. Over the past 40 years, Creatinine serum has become the most common and cheap serum marker for kidney function. One of the most common complications in patients with PGK is anemia. Anemia in PGK can be caused by several factors such as EPO deficiency, iron deficiency, etc. One of the usual parameters checking is the iron status of TIBC. This study aims to determine the relationship of serum Creatinine level with TIBC in chronic kidney patients in Gambiran regional public hospital Kediri and sampling taken by quota sampling. The study used cross-sectional using Rank Spearman statistic test. This test is used for abnormally distributed data types. The measured variable was serum Creatinine level with TIBC. The results of this study indicate that the value of p = (0.000)&gt; α = (0.05), so H1 rejected and H0 accepted, then there is no relationship between serum Creatinine levels with TIBC in patients with chronic kidney disease in Gambiran Hospital Kediri.</p> Nala Fidarotul Ulya Gilang Kusdinar Kurniawan Santoso Copyright (c) 2019 Medical Laboratory Analysis and Sciences Journal 2019-05-01 2019-05-01 1 1 19 24 10.35584/melysa.v1i1.18 Low density lipoprotein (LDL) in type 2 diabetes mellitus <p>Hyperglycemia due to abnormal insulin secretion, insulin work or both. Type 2 Diabetes Mellitus is the most among other types of diabetes mellitus. Diabetes mellitus is usually accompanied by dyslipidemia. Dyslipidemia is a disorder of lipid metabolism or cholesterol characterized by an increase or decrease in lipid fraction in the plasma. Diabetes mellitus and elevated Low-Density Lipoprotein (LDL) cholesterol levels are often found to be interrelated. The purpose of this study was to describe Low-Density Lipoprotein (LDL) levels in patients with type 2 diabetes mellitus. The research design used was descriptive non-analytic. The population in this study were all patients with type 2 diabetes mellitus using a purposive sampling technique of 30 samples. Data collection was carried out by observing the medical record data of type 2 diabetes mellitus patients with Low-Density Lipoprotein (LDL) profile data for 2017. The results showed that patients with type 2 Diabetes Mellitus suffered the most by male sex with a percentage of 57%, aged over 45 years with a percentage of 97%, and having high LDL levels as much as 40%.</p> Andyanita Hanif Hermawati Eka Puspitasari Cholila Lailatul Nurmala Copyright (c) 2019 Medical Laboratory Analysis and Sciences Journal 2019-05-01 2019-05-01 1 1 25 29 10.35584/melysa.v1i1.19 Analysis quality characteristics of virgin coconut oil (VCO): comparisons with cooking coconut oil (CCO) <p>This study aims to examine the quality of cooking coconut oil (CCO) and virgin coconut oil (VCO). The analysis was carried out as a physical parameter test including organoleptic and density while the chemical parameter test was: free fatty acid (FFA) peroxide number and test of saponification number. The sample oil used comes from coconut oil made traditionally by virgin coconut oil or commonly abbreviated as VCO, which is coconut oil which passes through a different extraction process with ordinary coconut oil so it is believed to have higher quality and provide more benefits. Samples derived from coconut oil traditionally processed in Beji Village, Boyolangu District with the brand "MALIKA". It was found that both oils had relatively the same physical parameters, the difference in density on VCO and CCO: 0.88 g / ml and 0.82 g / ml. As for the chemical parameters of free fatty acids, peroxide numbers, and saponification numbers of the VCO and CCO comparisons: 0.165: 0.207; 0.54: 0.68; 203: 321, so that the overall VCO has good quality, while CCO has an unfavorable saponification number.</p> Dewi Natalia R Ayu Natalia Fendri Lukmanto Ika Ani Indra Lasmana Tarigan Copyright (c) 2019 Medical Laboratory Analysis and Sciences Journal 2019-05-01 2019-05-01 1 1 30 36 10.35584/melysa.v1i1.20
