Documenting lab activity promotes safety, provides data useful in safety analysis and planning and creates a paper trail that can be used as evidence of compliance with local, state and federal regulations. Whether in academia or industry, the chemical laboratory must operate in compliance with a large number of regulations. Laboratory records play a large part in incident and accident investigation. Records and documents should be created with very specific goals in mind. They should be designed to meet these goals, preferably by those who ultimately will use them and be “standardized,” as much as possible. They should be subject to change control and retained for a prescribed period of time under conditions that will maintain their integrity. Having approved, written standard operating procedures (SOPs) in place for routine laboratory unit operations provides lab management with another way to leverage safety at the bench level.

The Chemical Hygiene Officer must play an active role and have a strong presence in the lab, providing feedback and expertise and keeping lines of communication open between lab workers and management. The efficient facility run with good administration reflects a superior understanding of division of labor and conflict of interest. Although the operation may be seen from the outside as a large, well-lubricated machine, it is made up of many smaller parts and “safety” is one of the key lubricants.

AbstrakKeberadaan laboratorium kimia dan biokimia di FIK-UI diperlukan sebagai perangkat penunjang akademik dalam proses belajar mengajar, sebagai wadah penelitian dan pelatihan, serta untuk melakukan aktivitas yang berorientasi profit. Untuk membangun sebuah laboratorium kimia yang sehat dan aman perlu diadakan studi kelayakan perencanaan dalam merancang laboratorium kimia dan biokimia di FIK-UI. Metodologi yang digunakan dalam penelitian ini adalah studi pustaka dan observasi lapangan berupa kunjungan pada beberapa laboratorium kimia dan biokimia. Hasil penelitian menunjukkan bahwa dalam membangun laboratorium kimia dan biokimia yang sehat dan aman diperlukan prosedur pengoperasian baku yang memperhatikan kesehatan dan keselamatan kerja di laboratorium, ventilasi dan perlengkapan pelindung yang berfungsi baik, penataan bahan kimia dan peralatan laboratorium, serta adanya prosedur pengelolaan pengolahan limbah laboratorium sehingga tidak mencemari lingkungan. AbstractThe existence of chemical and biochemical laboratory at the Faculty of Nursing Science, University of Indonesia become important, because it’s function as academic supporting tool in the process of studying, as a place for lecturers and college student to do the researches and exercises and also can be used to do the activities which have profit orientation. In order to build a chemical laboratory which health and safety, it needs the feasibility study about planning in designing the chemical and biochemical laboratory at the Faculty of Nursing Science, University of Indonesia. The methodology which is used in the research is literature study and observation to some chemical and biochemical laboratories. The result of the research showed that to build a chemical and biochemical laboratory which health and safety, it needs to have standard operating procedures that consider about health and safety work in the laboratory, the ventilations and protective equipments which have good function, the arrangement of chemicals and laboratory equipments, and the management of laboratory waste treatment procedure to prevent the environment to be contaminated.

In this paper we present a comprehensive description of the design, fabrication and operation of an electrified Lab-on-a-Disc (eLoaD) system. The smart platform is developed to extend conventional Lab-on-a-Disc applications with an electronic interface, providing additional flow control and sensing capabilities to centrifugal microfluidics platforms. Wireless power is transferred from a Qi-compliant transmitter to the eLoaD platform during rotation. An Arduino-based microcontroller, a Bluetooth communication module, and an on-board SDcard are integrated into the platform. This generalises the applicability of the eLoaD and its modules for performing a wide range of laboratory unit operations, procedures, or diagnostic assays, all controlled wirelessly during spinning. The lightweight platform is fully reusable and modular in design and construction. An interchangeable and non-disposable application disc is fitted with the necessary sensors and/or actuators for a specific assay or experiment to be performed. A particular advantage is the ability to continuously monitor and interact with LoaD experiments, overcoming the limitations of stroboscopy. We demonstrate the applicability of the platform for three sensing experiments involving optical, electrochemical, and temperature detection, and one actuation experiment involving controlled heating/cooling. The complete electronic designs and example programming codes are extensively documented in the supplementary material for easy adaptation.

Abstract: Fat as a source of the greatest energy than carbohydrates and protein, and also serves as a source of vitamin A, D, E, and K. Fat consumption in excessive amounts can cause a coronary heart disease, high blood pressure, cholesterol, and atherosclerosis. Fatty level in fast food is high, such as the fried chicken and the current public interest on the fried chicken is extremely high. The objective study was to know a difference of fatty level on fried chicken at fast food restaurant and street food. This research was comparative with analysis technique against 10 fried chickens at fast food restaurants and also 10 friend chickens from street food which were taken selectively around the area of East Surabaya by using Soxhlet method that conducted at the Chemical Laboratory Unit of Surabaya Health Polytechnic. The analysis result was obtained the average value of the fatty level on fried chicken at fast food restaurant was 19.71% and street food of 25.29%. It can be concluded that there are differences in the levels of fat on fried chicken flour at fast food restaurants and street foods.Keywords: Levels of Fat; Fried Chicken Flour.

Enhancing the degree of functional multiplexing while assuring operational reliability and manufacturability at competitive costs are crucial components to enable comprehensive sample-to-answer automation, e.g., for use in common, decentralized “Point-of-Care” or “Point-of-Use” scenarios. This paper demonstrates a model-based ‘digital twin’ approach which efficiently supports the algorithmic design optimization of exemplary centrifugo-pneumatic (CP) dissolvable-film (DF) siphon valves towards larger-scale integration (LSI) of well-established “Lab-on-a-Disc” (LoaD) systems. Obviously, the spatial footprint of the valves and their upstream laboratory unit operations (LUOs) have to fit, at a given radial position prescribed by its occurrence in the assay protocol, into the locally available disc space. At the same time, the retention rate of rotationally actuated valve and, most challenging, its band width related to unavoidable experimental tolerances need to slot into a defined interval of the practically allowed frequency envelope. A set of design rules, metrics, and methods and instructive showcases for computationally assisted optimization of valve structures are presented.

Level Of Understanding

Abstract Response to Intervention (RTI) implementation is becoming more widespread due to the references of RTI components in the Federal Regulations. But everyone is not at the same level of understanding about RTI and its implementation. This article will answer several questions. What is RTI? Why are we hearing more and more about RTI? How are states implementing RTI components? How can the speech-language pathologist help in RTI implementation in the presence or absence of a specific RTI infrastructure? How is Florida Proceeding with RTI implementation? Are there any new resources available for principals and other educators who might want to learn more about RTI?
