Abstract

The objective of this research was to determine the potential effects of Sargassum hystrix extracts (SHE) on the glucose levels, lipid profile, and pancreas of streptozotocin (STZ)-induced diabetic rats. SHE at 200, 300, and 400 mg/kg was administered orally to STZ-induced diabetic rats once daily for 15 days. Glucose levels, lipid profile, and weight of rats were measured in the normal state and on the 15th day. The histology of the pancreas was observed on the 15th day. The results showed that the preprandial and postprandial glucose levels in the group treated with SHE at 300 mg/kg were significantly reduced compared with those of the diabetes group. Additionally, the levels of triglycerides and cholesterol in the 300 mg/kg SHE group were significantly different from those in the diabetes group. However, the levels of high-density lipoprotein cholesterol and low-density lipoprotein cholesterol across the treatment groups did not have significant differences. Necrosis was found in all STZ-induced rats. SHE at a dose of 300 mg/kg had the best capability to lower the levels of preprandial and postprandial glucose and to prevent necrosis in diabetic rats. read more

Padukuhan Temanggal II yang berada di Desa Purwomartani Kecamatan Kalasan
Kabupaten Sleman merupakan sebuah wilayah dengan potensi sangat baik untuk
pelaksanaan kegiatan perekonomian, khususnya pertanian dan perikanan. Suasana
kehidupan pedesaan yang masih sangat terasa, di area pemukiman yang dikelilingi
persawahan serta dilewati oleh saluran irigasi yang mengalir hampir sepanjang hari
sangat mendukung untuk pelaksanaan kegiatan pertanian dan perikanan. Rumah tinggal
penduduk rata rata masih memiliki sisa lahan kosong dalam bentuk halaman pekarangan
yang bila dimanfaatkan dengan baik, khususnya untuk kegiatan yang produktif di bidang
pertanian dapat sangat berperan dalam menyediakan sumber pangan mandiri bagi
keluarga dan warga di lokasi tersebut, misalnya kegiatan penanaman sayuran, budidaya
ikan dalam skala rumah tangga dan lain-lain. Kegiatan usahatani akan dapat menjadi
sumber tambahan untuk meningkatkan pendapatan keluarga, selain dengan
tercukupinya sendiri kebutuhan pengeluaran untuk pembelian bahan makanan, tidak
menutup kemungkinan sisanya dapat dijual untuk memenuhi kebutuhan warga lain atau
dijual ke pasar sehingga ada tambahan pendapatan yang berujung pada peningkatan
kesejahteraan warga. read more

Padukuhan Temanggal II located in Purwomartani Village, Kalasan District Sleman Regency is an area with very good potential for implementation of economic activities, particularly agriculture and fisheries. Except for farming/paddy field, Purwomartani also have a big potency in aquaculture or fish farming since the area has a good irrigation and water supply. Kelompok Wanita Tani or Women Farming Group answer the potencies by inviting Bachelor in Fish Product Technology (BFPT) to guide and train the group to utilize their surrounding yard as fish pond and further process the fish into value added product. For this program, BFPT conducted a series of training to teach a good fish processing methods. In the first training, the women group were exposed by the potency of fish as a food source, the kind of processing and fish products, good manufacturing practices, the zero waste processing concepts, economical value of products, and group institution development. In the second training, BFPT gave a processing practice for fish processing especially for dried base products. read more

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

Mahasiswa diperkenalkan dengan budidaya air payau (komoditas udang), industri rumahan perikanan (nugget, otak-otak dll), industri pengalengan ikan dan tempat pelelangan perikanan di pelabuhan perikanan Pekalongan.

Growth Rate and Histamine Production of Klebsiella sp. CK02 Isolated from Skipjack Tuna Compared with Morganella morganii ATCC 25830 at Various Incubation Temperatures

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.
Keywords: growth rate, temperature, histamine, Klebsiella sp. CK02, M. morganii ATCC 25830 read more
