Chemical Education Study program S1 at Universitas Terbuka (UT) opened since 1986, provides laboratory works to ensure practical competencies of students with degree in chemical education. Accordingly, guidance is developed to manage the lab works which focus on step, materials, and support required for the lab works. While the guidance is developed in UT's main office, the lab works are conducted in (all 38) UT Regional Centre's. The UT Regional Centers have responsibility to provide lab schedule for all students registered in courses with lab work via all communication media, namely SMS, email and phone. Before starting the lab works. UT Regional Centers have to explain requirements and procedures of the lab works to the students. UT Regional Centers have also been responsible to recruit and employ qualified instructors based on requirement written in the guidance. After years of implementation, it is necessary to evaluate the effectiveness of the lab works. The study that reported here is aimed at analyzing student's perceptions of lab works' quality and constraints. The study was conducted and involved 24 persons from UT Regional Centers, student registered in the first and second semester of 2014 academic year, 8 of 38 UT Regional Centers (because students registered in courses only half of the total Regional Centers). Data were gathered through questioners. Analyzed using mix method qualitative. Qualitative with video conference. Results shows that students had positive perception toward lab work implementation. However, there was a tendency of students to work in groups, not individually as required, due to limited circumstantial situation. In some UT Regional Centers, lab work could only be conducted in place far away from the office that cause difficulty for students to attend. In term of the guidance, students perceived lab works to be good although not entirely helpful.

This paper presents a low-cost and disposable paper based microfluidic analysis system for point-of-care diagnostics. Detection is achieved by using a colorimetric or visual indicator. Immobilized specific reagent or enzymes designed for the parameter under consideration act as capture molecules on the surface of the detection zone. The sensor is integrated into a microfluidic system made of paper (cellulose). An additional component of the analysis system is a capillary unit which is used to introduce the analyte to the detection zone. For this purpose well- defined, millimeter-sized channel, comprising hydrophobic polymer bounded onto hydrophilic paper was created. Then the detection zone was coated with a sensitive reagent layer as a sensor region. The paper based microfluidics also called lab on paper, has been fabricated using screen printing technology as the basis for low-cost, disposable, portable and technically simple fabrication for mass production. Microfluidics in paper make it feasible to run single, dual or even multiple clinical analyses on one strip of paper while still using only small volumes of a single sample. The capability of lab on paper for detection of importance clinical analyte protein in urine, saliva and blood samples has been demonstrate successfully. Lab on paper as a diagnostic system is small, disposable, and easy to use and requires no external equipment, reagents, or power sources. This kind of diagnostic system is attractive for use in developing countries, in the field, or as a low-cost alternative to more-advanced technologies already used in clinical diagnostics. Keywords: Lab-on-a-paper, Point-of-care, Visual detection, Clinical diagnostic, Disposable sensor
