Salah satu komponen turbin yang penting untuk diperhatikan dalam pembuatanya adalah komponen runner dan casing turbin. Banyaknya bagian yang harus dilas dan penggunaan alat bantu yang belum memenuhi syarat fungsional menyebabkan terjadinya beberapa masalah ketika proses perakitan, permasalahan tersebut disebabkan sulitnya mendapatkan ketegak lurusan antara piringan dan poros runner dimana pada kedua komponen tersebut terjadi penyimpangan runout yang melebihi toleransi yang diijinkan, seperti halnya perakitan komponen casing yang dimana hampir seluruh sambungan mengalami proses pengelasan dan penggunaan alat bantu yang sederhana sehingga menyebabkan penyimpangan dimensi yang sangat besar dari toleransi yang ditentukan. Penggunaan alat bantu yang sangat sederhana akan menimbulkan kesulitan dalam mengontrol dimensi atau keseragaman bentuk selama berlangsungnya proses produksi. Untuk itu dibutuhkan fixture yang cocok untuk proses perakitan runner maupun casing turbin untuk mendapatkan proses perakitan yang sesuai toleransi geometri yang ditentukan. Penelitian ini membuat rancang bangun fixture untuk digunakan dalam perakitan runner dan perakitan casing turbin dengan metode perakitan dilakukan secara bertahap. Perancangan dilakukan dalam lima tahap yaitu tahap pernyataan persoalan, tahap pembuatan analisa kebutuhan, tahap pengumpulan informasi dan gagasan, tahap pembuatan rancangan sementara dan tahap pembuatan rancangan akhir. Sedangkan pembuatan fixture dilakukan dalam dua tahap yaitu pemesanan material (pembelian material) dan pembuatan komponen fixture. Hasil akhir dari pembuatan runner dan casing dengan menggunakan fixture adalah mampu menurunkan penyimpangan pada komponenÂ  runner dan casing turbin denganÂ  menghasilkan runout pada runner sebesar 2.0 mm dan ketegak lurusan casing sebesar 1.6 mm, tetapi belum mampu mencapai penyimpangan dari yang ditargetkan yaitu 1 mm.

Penelitian ini bertujuan untuk mengetahui pengaruh variasi quenching bertingkat dengan menggunakan media pendingin oli dan air pada baja AISI 1045 terhadap sifat mekanik dan struktur mikro. Sifat mekanis yang dianalisa meliputi uji kekerasan, uji impak dan pengamatan struktur mikro. Metode yang digunakan yaitu diawali dengan proses Perlakuan Panas (Heat Treatment) pada temperatur 850Âº dengan waktu Penahanan (Holding Time) selama 4 jam. Setelah itu dilanjutkan Pendinginan Cepat (Quenching) dengan volume air dan oli yang divariasikan untuk setiap spesimen. Nilai kekerasan tertinggi didapatkan pada media pendingin air saja tanpa campuran oli sebesar 71.74 HRC atau meningkat sebesar 796.75% atau delapan kali lipat dari kekerasan raw material sedangkan kekerasan terendah dari variasi oli dan air tejadi pada variasi 50:50 (%) sebesar 46,38 HRC atau meningkat sebesar 475% atau hampir lima kali lipat. Kekuatan impak baja AISI-1045 cenderung mengalami peningkatan kekuatan pada media pendinginan air + oli diatas 10% dibandingkan raw material, ini menunjukkan bahwa semakin tinggi jumlah volume oli terhadap air sebagai media quenching, maka akan meningkatkan keuletan baja namun menurunkan kekerasan baja. Jenis variable pendinginan yang menghasilkan baja yang tangguh (keras dan ulet) adalah pada variable quenching air 80:20 (%) oli dan air 70:30 (%) oli. Namun, berdasakan pertemuan dua garis linear pada grafik perbandingan nilai kekerasan dan impak, ditemukan perbandingan variasi pendinginan yang paling optimal yakni pada variasi air 68% dan oli 32%.

Background: Lateral epicondylitis is seen more commonly in non-athletes than athletes. Non-operative methods are the mainstay of treatment being effective in more than 95% of cases. Platelet rich plasma (PRP) has shown promising results in many studies as compared to steroid injection & other modes of conservative management. Hence, this study was done to evaluate PRP efficacy in our clinical setup and in the people of age group most commonly being affected.

Methods: This randomized study was conducted at Gandhi Medical College & Hamidia Hospital, Bhopal, for a period of two years from Aug 2015 to Sep 2017 on 60 consenting patients diagnosed as suffering from lateral epicondylitis. Using lottery method for randomization the patients were divided into two groups, based on which the treatment was received. Group –1 with 30 patients received 2 ml of PRP. Group –2 with 30 patients received 2 ml of Triamcinolone injection. The data collected and recorded in the appropriate proforma. Post therapy assessment was done using with Oxford elbow score.

Results:  Average age at presentation was 31.11 years, Range of age was from 20 to 40 years. Maximum incidence was in the age group of 35 to 40 years.

Female preponderance was observed in Group 1. Most common presenting complaint was elbow pain seen in 100% of cases. Most common side involved was the dominant side right side involvement was seen in 41 cases and left side in 19 cases. The Oxford elbow score pre-treatment in all the groups was not statistically significant and the Oxford elbow score at the end of 6 weeks,12 weeks and 24 weeks treatment showed that PRP is better than  steroid  in control of pain.

Conclusion: Lateral epicondylitis/Tennis elbow is a painful debilitating condition of elbow, which creates disturbance in functional activities. A single injection of PRP at the site of the elbow pain resulted in relief of pain in patients with longer duration as compared to local steroids to other conservative treatments.

Published: July 2019

It is well known that medium-sized molecules (MSM) affect the tone of smooth muscle structures of organs and the transvascular transport system. MSM also can pass through placental barrier and intoxicate fetus, resulting in multiple organ damage. The goal of the work was to determine the level of endogenous intoxication in cow’s organism on the last trimester of pregnancy and under the influence of the “Prodovit-tetra” and “Nanovit” preparations, as well as calving process and after it. Experiment was conducted in LLC “Agroprodservice invest” of Ternopil oblast on the cows of Ukrainian black-and-white dairy breed. Biochemical studies conducted in the laboratory of veterinary obstetrics and gynecology of the Ternopil Research Station of the Institute of Veterinary Medicine of the NAAS. One control and two experimental groups of animals were used for this experiment. Cows of the first experimental group received 15.0 ml of “Prodevit-tetra” preparation intramuscularly on the 35–25 day before calving. Blood was taken from the observed animals before and after administration of the medicines. The level of endogenous intoxication of the cow’s organism were determined by the concentration of MSM in their blood and prooxidant/antioxidant index. Concentration of MSM in the blood of cows after administration of “Prodevit-tetra” reduced by 41.0% and after administration of “Nanovit” containing metal nanoparticles – by 61.0% that promoted increase of prooxidant/antioxidant index by 1.7 and 2.3 times (Р ≤ 0.001) compered to initial indicators and indicated the positive effect of preparations on the cow’s organism. Application of the “Nanovit” preparation showed better result, therefore we can recommend it to be used in scheme to reduce intoxication of the cows during the dry period and to prevent postnatal pathology. The results of the experiment suggest that multivitamin complex “Nanovit” could be used for reducing of intoxication in the body of cows during dry period and to prevent postnatal pathology. In the future, we will study effect of the “Nanovit” preparation on the humoral immunity of cows in dry period and after calving and possibility of “Nanovit” usage in the system of prevention of obstetric pathology as well.

Published: July 2019

One application of communication from the 5G network in the future is to implement Device to Device (D2D) into heterogeneous multi-tiered communication networks consisting of small cell communications between eNB, cellular and D2D. The application of D2D is useful for the future even though it has several problems with one of them being interference with the frequency of other devices in the same cell. This can affect Quality of Service (QoS) in D2D communication so that it requires the application of a resource allocation distribution that can increase data rate and reduce interference. One of the algorithms used for the distribution of resource allocation in communication network systems is the Auction allocation algorithm. The auction allocation algorithm introduced in this journal provides a solution to divide resources fairly for all D2D pairs. The data rate increases by increasing the number of resource blocks and decreasing the cell radius.

This substance is very important, especially in metabolic processes such as breaking protein into amino acids needed for the growth of babies, children, and also helps maintain the function of carbohydrates as an energy source. The purpose of this study was to determine the effect of extracts on nutrient levels of skipjack (Katsu wonu spelamis) fufu (smoke). This study used a completely randomized design, with two treatments (the use of preservatives and without preservatives) with 3 replications. Based on the results of the study it was found that the extract of the welch starfruit leaves did not significantly affect the protein and fat content but significantly affected the water content.

This study aims to analyze crediting procedures. The research method used in this research is the descriptive method to describe crediting activities conducted by Cooperative Rahastra Credit Union in Bandung. This research uses the qualitative approach. The data obtained by using the research instrument is through observation, in-depth interview and documentation study. The results of the study indicate that crediting procedures include credit administration, credit documentation, credit approval, and credit processing. Implementation of credit procedures undertaken by the Cooperative Rahastra Credit Union in Bandung has not been maximized because there is still one indicator of lending procedures that have not been met. Indicators that have not been met is the stage of credit documentation, that is when doing credit analysis not all prospective borrowers through the credit analysis phase. Cooperative Rahastra Credit Union still uses the element of subjectivity in assessing prospective borrowers. As a result of not applying this credit analysis resulted in the addition of bad credit.

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.

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)> 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.

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.

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.
