Authors: Isroni W , Bahri A S , Amin A A 
Published: February 2020

Abstract

Eucheuma cottonii is widespread in coastal areas. The content of seaweed in the form of agar, carrageenan, and alginate causes seaweed to have an important meaning in industry. The problem currently faced is the lack of production of seaweed for industrial materials, caused by the lack of growth rate. The community’s understanding is that the more weight the seedlings plant, the more yields will be obtained and the faster to harvest. But in reality, the less weight the seeds planted, the faster the rate of growth, so that the seeds needed are not so many and produce a lot of harvest. The purpose of this study was to determine the effect of different initial seed weights on the growth rate of E. cottonii seaweed. This research is an experimental study, using a Completely Randomized Trial Design consisting of one factor and six replications. While the treatment used is the initial weight of different seedlings, ( 25 gr, 50 gr, 75 gr, and 100 gr). This research was conducted in the waters of Lamawalang District, Larantuka City, East Flores Regency. Data analysis technique used one-way ANOVA (one factor) with the Least Significant Difference Test level of 5%.

Abstract
Goatfish is one of the most dominant demersal-fish species currently caught by local fishermen in North-Coast of East Java and Madura using modified Danish-Seine. This research aimed to investigate species diversity goatfish and spawning potential ratio (SPR) of most representative species, U. suphureus. Identification was completed through morphometric and meristic investigation. A total of 2,550 fish were sub-sampled from catches for length-frequency analysis, length at first maturity (Lm), length-weight relationship and SPR. The results showed that there were five species within catches, being: U. sulphureus, U. moluccensis, U. tragula, U. sundaicus, and P. heptacanthus. Length-weight followed cubic formula with Wt = 0.0159 * Lt3.124 (p< 0.05; r2 = 0.92). Female length-at-first mature was reached at 11.67 cm Fork-Length, with total female biomass in the sample 6.5 kg. Total biomass was 93.1 kg, hence the SPR was < 7%. The minimum value of SPR while maintaining stock at good parent stock was >20%. From these results, it was very clear that demersal fishery in North-Coast of East Java, represented by U. sulphureus is unsustainable. Management measure, either size or effort limitation should be implemented, otherwise, the stock will soon collapse.

Antigen Candidates for Atherosclerosis Vaccine Development
Authors: Putri D K S C , Al-Farabi M J , Suryawan I G R 
Published: February 2020

AbstractAtherosclerosis is a major cardiovascular issue in the world. Atherosclerosis has long been theorized to be originated from foam cells that build up due to the chronic inflammatory process of cholesterol deposition in the walls of blood vessels and the uptake of oxidized LDL (OxLDL) and phosphorylcholine. Until now, the treatment for atherosclerosis has been focusing on drugs that inhibit the progression of atherosclerotic plaques. Recent findings show that proper regulation of immune cells, both adaptive and innate, has been shown to have a relationship with the prevention of atherosclerotic lesions. The future of vaccination as prevention for atherosclerosis holds great potential, considering studies are abundant in proving the atheroprotective effects of the immunization with several types of antigens. In this literature review, we will discuss the types of antigens which hold promising potentials for atherosclerosis vaccine development and its future challenges.
Late Eyelid Reconstruction of Necrotizing Fasciitis
Authors: Muthie F A , Sutjipto  
Published: February 2020

Abstract
Necrotizing fasciitis (NF) is a devastating severe infection. NF involving periorbital tissue is rarely found. We reported a 42-year-old woman with eyelid edema surrounded by necrotic tissue and pus production for about a week. LRINEC score was 6. Widespread local excision and debridement were urgently performed. Reconstruction performed two weeks after the onset. The rotational flap is taken from her forehead to prompt good skin remodeling and vascularization. A part of the flap slipped underneath the temporal skin. The flap was perfectly grown, and the eyelid function recovered. NF is a rare severe infection and rarely involves the periorbital area. Early recognition is critical. LRINEC score could be used, and urgent debridement is needed. Late skin flap could be a choice to cover the debrided skin and give a good aesthetic yet functional eyelid.

Published: February 2020

Abstract
Left ventricle (LV) remodeling often occurs after acute myocardial infarction (AMI), and early detection and prompt treatment on this condition may improve prognosis of the patients. Basal soluble ST2 and Global Longitudinal Strain (GLS) 2D-speckle tracking echocardiography can detect early changes before LV remodeling occurs. This is an analytic observational study using one group pre-test and post-test design for correlation. Forty-five patients of AMI during August until December 2015 from ICCU and cardiology ward were analyzed and followed up for 12 weeks. There were 45 subjects with AMI, 38 (84.4%) patients with STEMI and seven (15.6%) patients with NSTEMI. There were significant differences of left ventricle end diastolic volume (LVEDV) baseline from 76±29.69ml/m2 to 98.11±36.84ml/m2 after 12 week follow-up (p=0,003). There was significant correlation between high baseline soluble ST2 with and low GLS baseline with LV remodeling (p=0.015). High baseline soluble ST2 and low GLS value can predict LV remodeling in patients with AMI.

Published: February 2020

Abstract
Left Atrial (LA) pressure and the trans-mitral pressure gradient chronically increases in Mitral Stenosis (MS), which results in LA enlargement and Pulmonary Hypertension (PH). We investigate the Left Atrial Volume Index (LAVI) as an indicator of severity and PH in MS. Fifty-nine subjects with MS (27 men and 32 women) mean ages 41.3±9.51 y.o were included in this study. We examined the correlation of LAVI and parameters of MS severity, and PH (Planimetry, MVA-PHT, MVA-VTI, MV-PHT, MV meanPG, TRmaxPG, and EstPASP). Most of the subjects had severe MS (77%), mild PH (40%) and AF (80%). LAVI value markedly increased in this study (Mean: 83.79 ± 38.32 ml/m2). In subjects with severe MS, LAVI was significantly higher than that in moderate MS (91.88±38.41 vs 54.83±19.28, p<0.05). LAVI was significantly correlated with Planimetry, MVA-PHT, MVA-VTI, MV-PHT, MV MeanPG, and EstPASP (-0.40; -0.42; -0.29; 0.42; 0.27 and 0.29, p<0.05, respectively). LAVI cut-off value as an indicator for severe MS was 59.72 ml/m2, with the sensitivity and specificity was 75.3% and 66%, respectively. LAVI was correlated well with severity and PH parameters in MS. LAVI also can be used as an indicator for severe MS.

Cluster of differentiation 36 (CD 36), ENac, and AQP 2 effects on heart
Authors: Sunariani J 
Published: February 2020

Abstract
Nowadays obesity, defined as an imbalance between food intake and exercising, has become a health concern worldwide. Obesity triggers many diseases, one of them being diabetes melitus (DM) type 2. Atherosclerosis is known to be linked with CD 36 and it can be identified as platelet integral membrane glycoprotein IV. CD 36 is known as thrombospondin-1 (TSP-1) which is found on gustatory cells, extracellular matrix (ECMs) and platelete a granules, therefore it has strong relationship with atherosclerosis. CD 36 can bind to oxLDL and induces prothrombotic state. Inspite of that, ENaC and AQP 2 also have a strong effect on heart, especially their role are often related to the heart failure (HF) because sodium and water are thought to be mediated through activation of arginine vasopression (AV), neurohormonal activity, the renal-angiotensin-aldosteron system (RAAS), and atrial natriuretic peptide that maintains cardiac output and blood pressure. This article is focused on the relationship of CD 36, ENaC, and AQP 2 effects’ on heart, including the molecular mechanism. This understanding needed to treat and to cure the heart diseases and prolong the sufferers life expectancy.

Abstract
As a chronic disease, heart failure may have a significant impact on a patient’s quality of life. There are conflicting study results regarding the relationship between systolic function and quality of life in patients with chronic heart failure. This study identifies the relationship between systolic function and quality of life in patients with chronic heart failure. This study was conducted on 34 consecutive Chronic Heart Failure (CHF) patients in Cardiovascular Department, Sosodoro Djatikoesoemo General Hospital. Left Ventricle Ejection Fraction (LVEF) was obtained from echocardiography, and quality of life was assessed using Minnesota Living with Heart Failure Questionnaire (MLHFQ). A low quality of life was defined as MLHFQ score ≥ 45. The correlation between LVEF and physical, emotional dimension, and overall score from MLHFQ shows significant results (p > 0.05). The correlation between LVEF and physical dimension and between LVEF and an overall score of MLHFQ shows strong negative degree (r = -0.727). The correlation between LVEF with both physical and emotional dimension shows negative strong degree (r = -0.678, the latter r = -0.547). There is a significant correlation between systolic function and physical, emotional, and overall quality of life in chronic heart failure patients.

Published: February 2020

Abstract
Tryptase, an enzyme secreted by mast cell, is suggested to play a significant role in the pathophysiology of acute coronary syndrome (ACS) and subsequent ventricular remodeling (VR). This study aimed to understand the correlation between the serum level of tryptase and VR in patients with ACS after one month of onset. Sampling method was total sampling where patients with ACS enrolled in the study were allocated into two groups based on their serum tryptase level, lower level (n=13) and higher level (n=12) groups. All subjects underwent echocardiography examination on admission to obtain their initial data and they were reevaluated one month later for the signs of VR. The occurrences of VR were examined by echocardiography with LVEDP and LVESV used as the VR parameters. Fisher Exact Test showed no significant difference between both groups in term of VR (p=0.668). The contingency coefficient analysis revealed no correlation between tryptase level and the occurrence of VR (p=0.113). However, the multiple regression analysis suggested that LVEDP and LVESV demonstrated multicollinearity to tryptase and VR. Although the current study concluded no correlation between tryptase level and VR following ACS, a prospective study with longer follow-up time is expected to gain more information.

Published: February 2020

Abstract
Heat treatment strategies for advanced high-strength medium-Mn sheet steels are addressed. A review of the available thermal cycles for cold-rolled and hot-rolled sheets are presented. The benefits from the intercritical annealing following hot-rolling are emphasized. The examples of intercritical annealing for the hot-rolled sheets of initial martensitic microstructure are provided. The heat treatment was performed in a temperature range of 680-720°C for various times from 1 to 5 hours. The material used in the experiment was a medium-Mn steel containing 0.16% C, 4.7% Mn, 1.6% Al, 0.2% Mo, 0.2% Si. The scope of the research included dilatometer tests, hardness tests and microstructural characterization. The effects of temperature and time on a stabilization of retained austenite are assessed. Intercritical annealing performed at 700 and 680°C allowed forming some stable retained austenite in the microstructure. Moreover, some coiling simulations for hot-rolled strips are described.

Abstract
The nickel-based superalloys belong to widely used materials for most demanding industrial applications. The design and the experimental verification of manufacturing technology of NIMONIC 80A turbine blade is presented in this paper. A finite element (FEM) simulation was exploited for the closed die forging technology optimization. Based on the precision material model and boundary conditions, the deformation behaviour in the range of hot working temperatures was studied. The process conditions including the strain rates were preset according to the industrial scale practise. Based on the FEM simulation results the necessary tools were manufactured and the experimental closed die forging of turbine blades was performed. Subsequently, a heat treatment of forged blades was carried out. The minimum of 1300 MPa tensile strength was achieved. A metallographic survey was carried out to verify the structure homogenity.

Published: February 2020

Abstract
The work presents the results of coiling simulations of two medium manganese steels containing 3 and 5% Mn. The steels were subjected to the heat treatment including an austenitization at 1000°C for 300s and next isothermal holding at temperatures of 750, 700, 650 and 500°C for duration of 5 hours. The results of dilatometric analysis showed that in case of the 3Mn steel the ferritic transformation occured during the isothermal holding at 750 and 700°C. The amount of ferrite created during this step at 750°C was smaller compared to 700°C. Lowering the temperature to 650°C led to a transformation lack during the holding time. At 500°C a bainitic transformation occurred. Increasing the manganese content resulted in prolonging the incubation time before any transformations. For the 5Mn steel for all isothermal holding temperatures no transformation occurred within 5 hours. The conclusion was that manganese shifted significantly the ferritic and bainitic regions to longer times.

Abstract
A new programme, called ‘Skill India’, was launched in March 2015. The main goal of “Skill India” is to create opportunities and scope for the creation of the new talents of the Indian youth and also to identify new sectors for skill development. This programme targets of providing training and skill development to 500 million youth of our country by 2020, covering entire India. Now as the time is passing and we are getting new skilled labour we have a new problem of providing job to this skilled youth. The Start Up programme is set to meet such requirements but it is not enough to fulfil the job requirements of the skilled human power. Also, this is not very easy to set a new industry in a short span of time. So in this paper, I have tried to provide a new solution for increasing job opportunities in the existing industry. I tried to increase one more shift i.e. from existing 3 shifts to 4 shifts per day by reducing the working hours from 8 to 6. I got very exciting results which can be recommended for other industries also.
