Indonesian Society for Fish Processing Technology or Masyarakat Pengolahan Hasil Perikanan Indonesia (MPHPI) held the 12th scientific meeting in 2020 by on-line system due to Covid-19 pandemic on September 1-2 2020. In this year BFPT UGM was appointed as the organizing committee.  Held together with Semnaskan UGM (an annual national seminar in fisheries science organized by Department of Fisheries UGM), BFPT successfully invited 4 keynote speaker related to fish processing technology and many researcher from various University and research Institute to disseminate their recent research activities. Dr. Nurfitri Ekantari as the chairman of the committee said that all achievement of this seminar activity could not be separated from the support of all committees and participants. read more

Abstract

One of an important quality parameter in tuna is the level of histamine content. The contamination of histamine in tuna is mainly due to the activity of histidine decarboxylase produced by the bacteria. A rapid growth of histamine producing bacteria is correlated with the practice of temperature abuse during handling. This study aimed to develop predictive growth modeling of two histamine-producing bacteria in the function of temperature. The growth and histamine production of Klebsiella sp. CK02 and Morganella morganii ATCC 25830 at various temperatures were measured in tryptic soy broth histidine (TSBH) and tuna fish infusion broth (TFIB) growth media. Broths were incubated at 4°C and 15°C for 7 days, and at 30°C and 40°C for 24 hours. The Baranyi and Roberts model was used with DMFit to determine primary growth kinectics, and the Ratkowsky square root model to describe bacterial growth rate as a function of temperature. Histamine production was enumerated by the apparent yield factor (pYhis/ CFU) value. Growth rate increased with temperature, with a maximum rate at 40°C for Klebsiella sp. CK02 (0.740 log CFU/h) and M. morganii (0.578 log CFU/h). The Tmin for Klebsiella sp. CK02 in TFIB was -8.9°C, indicating better survival in low storage temperature, compare to M. morganii ATCC 25830. In addition, Klebsiella sp. CK02 produced a lower pYhis/CFU at 15 and 30°C compared to M. morganii ATCC 25830.

Department of Fisheries held a 56^th anniversary on September 1st 2019 by organized an event for Department member including lecturer, staff and students. Starts with walked around the campus, the event continued with door prized draw and lunch with all fish menu.

As an annual event, this year on 22-23 August 2019, Department of Fisheries again Kenal Perikanan (introducing fisheries sector to new students) by visited Pekalongan City in Central Java. Students were introduced to brackish water aquaculture (shrimp commodity), fisheries home industries (nugget, otak-otak etc.), fish canning industry and fisheries auction spot at Pekalongan fishery port.

In the context of continuous improvement and increasing competitiveness at the national and international levels, the Bachelor in Fishery Product Technology (BFPT) is preparing to apply for ASIIN international accreditation. ASIIN which stands for Accreditation Agency for Study Programs in Engineering, Informatics, Natural Sciences and Mathematics or in Germany Die Akkreditierungsagentur für Studiengänge der Ingenieurwissenschaften, Informatik, Naturwissenschaften und Mathematik, is a non-profit association engaged in education and was founded in July 1999. ASIIN provide expert support to German and international universities in the implementation of accreditation procedures at the study program and institutional level in the fields of engineering, natural sciences, mathematics, computer science and medicine and economics. Until now, ASIIN has accredited 5382 study programs in 43 countries including Indonesia. read more
