The honey samples were collected from the area of Bukit Goh, Kuantan, Pahang. Physicochemical analyses of parameters such as electrical conductivity and pH values have an important part in defining the overall properties of the honey and acquiring the quality of stingless bee honey in both type of pump. The data from the electrical conductivity shows that the honey samples from the diaphragm vacuum pump and peristaltic pump are 0.48 – 0.95 mS/cm and 0.25- 0.80 mS/cm respectively. Meanwhile, the data from the pH shows that the honey samples from the diaphragm vacuum pump and peristaltic pump are in range of 3.32 – 3.53 and 3.39 – 3.5 respectively. From the research, the value of electrical conductivity of honey sample from diaphragm vacuum pump is slightly higher than peristaltic pump but the pH values of the both pump are same in values. In conclusion, the peristaltic pump can maintain the physicochemical characteristics of stingless bee honey eventhough the both pumps have different in many ways. specialized Siti Nur Atikah Mohd Noor Faculty of Engineering Technology Project Paper (Bachelor Degree in Energy and Environment with Honors) -- Universiti Malaysia Pahang – 2019 Includes bibliographical references Faculty of Engineering Technology Dissertations Universities and Colleges Dissertations Theses THE0008610(Local) UMP 200217 20251125105521.0 eng
