The Effects of Different Concentrations of Bay Leaf Extract on Shelf Life of Preserved Scad Fish
Authors: Fuaidah Pramaziyah , Triastuti Juni , Pramono Heru
Published: October 2021

Scad fish (Decapterus kurroides) is the most productive fish species. To provide the added value, fishermen can process scad fish into various forms of processed products, such as preserved fish, which extend the shelf life. In order to extend the shelf life of canned fish, natural preservatives could be used that contain antimicrobial agents, such as bay leaves. The present study aimed to determine the effects of bay leaf extract in different concentrations on the shelf life of preserved scad fish. In the present study, the completely randomized design was used as an experimental research method. The treatments given differed in terms of the concentration of the bay leaf extract. The groups were treated as the scad fish without bay leaf extract (A), scad fish soaked in 6% of bay leaf extract (B), scad fish soaked in 7% of bay leaf extract (C), scad fish soaked in 8% of bay leaf extract (D), and scad fish soaked in 9% of bay leaf extract (E). The analyzed parameters included the total plate count, pH, and water level test using Analysis of Variance (ANOVA). The supportive parameters observed included an organoleptic test. The results indicated that the lowest total bacterial count from the beginning to the end of the experiment (18 hours) occurred on treatment C (7% of bay leaf extract addition), which was 1.54 × 103 to 5.85 × 106. Regarding the water level test from the beginning to the end of the experiment, treatment A (control) was not significantly different from other treatments. The difference in the concentration of bay leaf extract on scad fish effectively inhibited the growth of bacterial colonies. In conclusion, adding bay leaf extract to scad fish could inhibit bacteria for up to 12 hours. Treatment C (7% of bay leaf extract) gave the best results since this concentration level could inhibit the bacteria on scad fish.

Published: October 2021

Marine fish, particularly the red snappers, are often exposed to helminth parasitic infestation. As a result of the parasitic infestation, the fish population, the fish weight, and the morphological changes in the fish are shrinking. The present research aimed to find out the intensity and predilection of the helminth ectoparasites over the infection of the red snapper (Lutjanus argentimaculatus) and employed the survey method for this purpose. The sampling was carried out by the purposive sampling technique. The sample obtained consisted of 30 fish, 20% of the total red snapper population of 150 fish reared in the floating net cages of Balai Besar Perikanan Budidaya Laut Lampung. The intensity of the fish infestation by a mixture of Haliotrema epinepheli and Benedenia epinepheli was 132.5 individuals/fish. Neobenedenia girellae and Haliotrema epinepheli infected fish with an intensity of 149.41 individuals/fish. The 66.7% of Benedenia epinepheli had a predilection for the dorsal fin, and 33.3% for the anal fin. In Neobenedenia girellae, 57.1% had a predilection for the body surface, 37.2% for the head surface, and 5.7% for the dorsal fin. In conclusion, all sampled fish were positively infected with helminth ectoparasites, including Neobenedenia girellae, Haliotrema epinepheli, and Benedenia epinepheli.

Themelimi i Normales shënon një ngjarje të madhe dhe pikë referimi në historinë e arsimit dhe të shkollës kombëtare shqipe. Ajo ishte shkolla e parë e mesme profesionale, pedagogjike shqipe në gjeografinë shqiptare. Ishte shkollë kombëtare, jo vetëm nga forma dhe përmbajtja, por edhe për faktin se nxënësit, mësimdhënësit dhe veprimtarët e saj ishin nga vise të ndryshme të Shqipërisë etnike dhe nga ngulimet e diasporës shqiptare. Ishte institucion iluminist me të cilin u bashkua dhe identifikua një komb i tërë. Normalen e Elbasanit, Luigj Gurakuqi fillimisht e përkufizoi si “shkollë të madhe për mësonjës”. Zyrtarisht u quajt Shkolla Normale e Elbasanit, u mbiquajt “Normalja e Xhuvanit” (për nder të drejtorit, ideatorit dhe profesorit shumëvjeçar të saj, Aleksandër Xhuvanit), ndërsa studiuesit e mëvonshëm, duke iu referuar kontekstit historik, funksionit dhe rëndësisë së saj për arsimin e shqiptar, atë e cilësuan “akademi pedagogjike”, përkatësisht “universiteti i parë shqiptar”.
Towards a Multiple Language Shift in Cameroon
Authors: Safotso Gilbert Tagne
Published: October 2021

This paper examines Cameroonians’ use / attitudes to French, English, Cameroon home languages, and other variables to better project the future of those languages in Cameroon. The data analysed were collected through a questionnaire administered to 349 secondary school learners of three regions of Cameroon and 943 students  of the Universities of Dschang, Douala, Buea and Maroua (N=1292). The findings show that a few young Cameroonians speak their mother tongues, but would like their future children to speak them and to be multilingual. This is a quite contradictory situation as those children will have nobody to acquire those languages from. An important number of young French-speaking Cameroonians would prefer English as language of instruction and would like to abandon French in future.
