Nowadays, milk is one of the favorite drinks for Indonesian people. This relates to the awareness of society about healthy food is increasing. At the same time, there are many milk retail that are appearing. The purpose of this study was to detect the presence and level of contamination of Salmonella sp. in processed milk from milk retail around the students settlement area of ​​IPB University. In Indonesia the standard for identifying Salmonella sp. refer to Indonesian National Standard 2897: 2008. This method consists of 5 stages: pre-enrichment, enrichment, selective media planting, confirmation based on biochemical and serological tests. Milk samples in this study came from 14 milk retail in the students settlement area of the IPB University. The milk samples were taken are plain milk (milk that has not added flavor (flavorings), sugar, and ice). The selection of milk retail is taken within a radius of 2 km from the midpoint of the IPB campus in the Dramaga and Cilibende areas. Based on the results of this study, it was found that all milk samples examined showed negative results which means no Salmonella sp. contamination was found. From this study it can be concluded that the quality of processed milk sold in milk retail around the student settlement area of IPB University is good.

The aim of the present study was to investigate the production of extracellular enzymes in a number of twenty six autochtonous Saccharomyces and nonSaccharomyces strains selected in Dealu Mare region for wine production. The strains were screened for the production of extracellular b-glucosidase, esterase, pectinase and protease activity by inoculation the yeast strains onto selective media. All Saccharomyces tested strains showed at least two enzymatic activities while nonSaccharomyces strains showed activity at least for one enzyme. The weakest activity was recorded in case of β-glucosidase. Most of the tested strains exhibit more or less intense activity for polygalacturonase/pectinase and protease. This study put into evidence the potential of autochtonous and especially of non-Saccharomyces strains as source of production of secondary compounds which can play an important role in improving the quality of wines.

The present study was conducted to know the chemical qualities and adulteration of fresh raw milk collected from local markets (Bhangnamari bazaar, Sutiakhali bazaar, Vabokhali bazaar, Shombhuganj bazaar and Mymensingh sadar bazaar) of Mymensingh sadar, Bangladesh. Milk samples were analyzed for chemical parameters (contents of acidity, total solids, solids-not-fat, fat, protein and ash) and adulteration (presence of formalin, sugar or starch). Also, lactometer reading was recorded to monitor the specific gravity of the collected milk samples. Result showed that the specific gravity of milk from different sources differed non-significantly. The total solids, fat and protein contents of all the samples were in normal range except the milk fat content collected from Shombhuganj bazaar (32.66±4.04 g/Kg) and Mymensingh sadar bazaar (30.66±4.51 g/Kg) which had less (p<0.01) than the minimum legal standard of milk fat (35.00 g/Kg). The solids-not-fat content of the milk samples collected from Bhangnamari bazaar (72.93±8.78 g/Kg) and Vabokhali bazaar (79.33±6.81 g/Kg) were less than that from Mymensingh sadar bazaar (95.67±11.72 g/Kg). Developed acidity was detected in the samples from Bhangnamari bazaar (0.180±0.03), Sutiakhali bazaar (0.187±0.04%) and Mymensingh sadar bazaar (0.180±0.02%), while other samples were found to the fresh (0.150-0.157%). All of the adulteration tests showed negative results. The results suggested that though there were some fluctuations in quality among the bazaars regarding the standard of parameters, the raw milk samples were of acceptable quality.Bang. J. Anim.

Assessing scientists using exploitable metrics can lead to the degradation of research methods even without any strategic behaviour on the part of individuals, via ‘the natural selection of bad science.’ Institutional incentives to maximize metrics like publication quantity and impact drive this dynamic. Removing these incentives is necessary, but institutional change is slow. However, recent developments suggest possible solutions with more rapid onsets. These include what we call open science improvements , which can reduce publication bias and improve the efficacy of peer review. In addition, there have been increasing calls for funders to move away from prestige- or innovation-based approaches in favour of lotteries. We investigated whether such changes are likely to improve the reproducibility of science even in the presence of persistent incentives for publication quantity through computational modelling. We found that modified lotteries, which allocate funding randomly among proposals that pass a threshold for methodological rigour, effectively reduce the rate of false discoveries, particularly when paired with open science improvements that increase the publication of negative results and improve the quality of peer review. In the absence of funding that targets rigour, open science improvements can still reduce false discoveries in the published literature but are less likely to improve the overall culture of research practices that underlie those publications.

The article discusses the reasonsfor an expert to participate in legal proceedings. The gnoseological reason for that consists of the bad quality of materials subject to examination that renders the examination either completely impossible or compromises objective, reasoned and reliable assessment of the findings. The procedural reason consists ofa proscription for an expert to collect evidence himself or herself. The author investigates into the ways of how an expert can participate in legal proceedings. If the defense invites an expert to participate in the proceedings, then it is recommended that his or her involvement should be in the presence of attesting witnesses and recorded in the protocol. In the course of the legal proceedings an expert has the following tasks: adding initial data, acquiring new initial data, understanding the situation of the incident, acquiring new objects to be studied, including samples for examination. An expert’s participation in legal proceedings differs from the participation of a specialist or an examination on the scene of the incident. The author describes the tasks that an expert solves in the course of legal proceedings, the peculiarities ofan investigation experiment practices, the selection of samples for an examination, inspection, interrogation.

Voice over Internet Protocol (VoIP) is a telecommunications technology that is able to pass the communication service in Internet Protocol networks so as to allow communicating between users in an IP network. However VoIP technology still has weakness in the Quality of Service (QoS). VOPI weaknesses is affected by the selection of the physical servers used. In this research, VoIP is configured on Linux operating system with Asterisk as VoIP application server and integrated on a Raspberry Pi by using wired and wireless network as the transmission medium. Because of depletion of IPv4 capacity that can be used on the network, it needs to be applied to VoIP system using the IPv6 network protocol with supports devices. The test results by using a wired transmission medium that has obtained are the average delay is 117.851 ms, jitter is 5.796 ms, packet loss is 0.38%, throughput is 962.861 kbps, 8.33% of CPU usage and 59.33% of memory usage. The analysis shows that the wired transmission media is better than the wireless transmission media and wireless-wired.

This study implements the auto start control system on an electric motor 3 phase C4Feeding pump when the discharge pressure is low-low (4.3 kg /cm²). The C4 feeding pumpmotor was initially manually operated from the local control station, this was very ineffectiveand inefficient because it still relied on the field operator to operate the pump motor and whenthe plant was in normal operating it is very risk if the field operator late to operate motor then itwill impact to quality of the product, and if the delay time to operate motor is too long then planthave to shut down, therefore improvement is needed in the C4 feeding pump motor controlsystem. In this paper, various types of 3-phase motor control are explained which allow it to beapplied to the C4 feeding pump motor that are on-off, inverter, and variable speed drive andefficient selection of the three systems control of the motor. Software and hardware used in thisthesis work are DCS CENTUM VP Yokogawa.
