Produksi dan Kandungan Nutrisi Maggot (Chrysomya Megacephala) Menggunakan Komposisi Media Kultur Berbeda

Tujuan dari penelitian ini yaitu : 1. Mengetahui jumlah produksi maggot dari perlakuan limbah ikan dengan komposisi media kultur yang berbeda. 2. Mengetahui nilai nutrisi yang terkandung dalam maggot. Penelitian ini telah pada bulan November sampai bulan Desember 2015 di kampus C Fakultas Perikanan Universitas PGRI Palembang, Kecamatan Sematang Borang Palembang. Dari hasil identifikasi siklus pertumbuhan maggot, maggot akan melalui tahapan pertumbuhan yang dimulai dari telur (24 jam), maggot instar 1 (18 jam), maggot instar 2 (3 hari), maggot instar 3 (3 hari), pupa (7 hari) dan lalat deawasa. Dari tahapan tahapan-tahapan siklus pertumbuhan maggot yang dimulai dari telur sampai menjadi lalat dewasa membutuhkan waktu 14 hari 18 jam. Produksi maggot tertinggi terjadi pada perlakuan D (limbah ikan 3 kg + ampas kelapa 3 kg) dimana maggot yang dihasilkan mencapai 1.149,88 gram. Biaya produksi pada perlakuan D sebesar Rp.72/gr dengan rendemen sebesar 8,2347%.Untuk produksi berat maggot terendah terjadi pada perlakuan A (limbah ikan 6 kg), maggot yang dihasilkan hanya 494,08 gram dengan biaya produksi Rp. 72/gr dan rendemen sebesar 8,2347%. Kandungan nutrisi kandungan protein maggot tertinggi diperoleh pada perlakuan C. Pada perlakuan C kandungan protein yang terkandung pada maggot sebesar 41,22% dan protein terendah terjadi pada perlakuan A dimana protein yang terkandung sebesar 25,22%.

A general framework for improving electrocardiography monitoring system with machine learning

As one of the most important health monitoring systems, electrocardiography (ECG) is used to obtain information about the structure and functions of the human heart for detecting and preventing cardiovascular disease. Given its important role, it is vital that the ECG monitoring system provides relevant and accurate information about the heart. Over the years, numerous attempts were made to design and develop more effective ECG monitoring system. Nonetheless, the literature reveals not only several limitations in conventional ECG monitoring system but also emphasizes on the need to adopt new technology such as machine learning to improve the monitoring system as well as its medical applications. This paper reviews previous works on machine learning to explain its key features, capabilities as well as presents a general framework for improving ECG monitoring system

Fungal peritonitis in Iranian children on continuous ambulatory peritoneal dialysis: a national experience.

INTRODUCTION. Fungal peritonitis (FP), causing catheter obstruction, dialysis failure, and peritoneal dysfunction, is a rare but serious complication of peritoneal dialysis. In this study, the frequency and risk factors of FP are evaluated in children who underwent peritoneal dialysis. MATERIALS AND METHODS. A retrospective multicenter study was performed at the 5 pediatric peritoneal dialysis centers in Iran from 1971 to 2006, and FP episodes among 93 children were reviewed. Risk ratios were calculated for the clinical and demographic variables to determine the risk factors of FP. RESULTS. Ninety-three children aged 39 months on average were included in study. Sixteen out of 155 episodes of peritonitis were fungi infections, all by Candida albicans. The risk of FP was higher in those with relapsing bacterial peritonitis (P = .009). Also, all of the patients had received antibiotics within the 1 month prior to the development of FP. Catheters were removed in all patients after 1 to 7 days of developing FP. Six out of 12 patients had catheter obstruction and peritoneal loss after the treatment and 5 died due to infection. CONCLUSIONS. Fungal peritonitis, accompanied by high morbidity and mortality in children should be reduced by prevention of bacterial peritonitis. Early removal of catheter after recognition of FP should be considered

Study of Solvent Debinding Parameters for Metal Injection Moulded 316L Stainless Steel

Solvent debinding is one of a crucial stage in Metal Injection Moulding (MIM) process. This process begins with the removal of the soluble binder components by using solvents such as heptane or hexane. In solvent debinding process, unsuccessful to achieve maximum binder removal will cause a defect to the compact such as crack and swelling. So to have an optimum solvent debinding parameters are very important to improve the quality of the compact. Optimisation of solvent debinding process parameters for MIM of Stainless Steel 316L has been testified in this study. Gas atomised stainless steel 316L powder was mixed with a multicomponent binder in a twin blade mixer at a temperature of 150 °C for 90 minutes. The feedstock was successfully injected at the temperature of 150 °C. The green compacts were kept in n-heptane for eight different debinding times ranging between 30 to 240 minutes at temperatures of 40, 50, 60 and 70 °C to remove the primary binder components. From the result, the optimum temperature and time for solvent debinding were recorded at 60 °C and 240 minutes. Solvent debinding temperature and time give a significant effect on the rate of paraffin wax removal
