Global fish oil production is between 1 to 1.25 million tones and primarily exploiting fatty fish such as menhaden, herring, pilchards, anchovy, and sardine among others. The main producing countries include Japan, USA, Chile and Peru. Yet, fish oil from developing countries end up as bio waste since only the flesh is utilized. This paper discusses a simple approach for utilizing the fish bio waste to produce oil andhow the oil quality and quantityis impacted by the extraction process. The visceral organs were collected from fish filleting factory and markets in Kisumu town and oil extracted by modified wet pressing method adopted from Blight and Dyer (1959). The effect of temperature and serial washing on the oil quality and quantity was assessed from extraction temperatures at800C, 900C, 950C and 970C, while employing three serial washing using distilled water and pineapple juice. The quality of the oil produced was then determined based on the proportion of omega -3, vitamin A and E, peroxide value, iodine value and free fatty acids. Statistical analysis was conducted using R-data analysis software at P<0.05 and ANOVA to determine significance. Results indicate that maximum extraction efficiency was achieved at 800C for 30 minutes where 157.66g of oil was extracted, when compared to 156.56g at 90ºC,156.49g at 95ºC,155.84g at 97ºC from a tissues of 171.25gin each case. It was concluded that the temperature manipulation procedures as per this study was reliable to produce maximum yield and can be adopted by oil producing plants.

Locally-sourced armourstone is used extensively in the construction of new sea defence structures throughout Bahrain, with hundreds of thousands of tonnes being placed on single reclamation projects. This armourstone is won almost exclusively from the local quarry, which outputs limestone of variable quality. An evaluation has been made into the quality of local rock for usage as armourstone, using observations on sites and at the quarry, as well as compliance test results from various projects undertaken in recent years. Attempts are made to quantify potential losses in-service, by using the two degradation models described in the CIRIA Rock Manual, which give markedly different estimates. The envisaged loss of mass is difficult to predict with great accuracy due to the high sensitivity of the models to material and site parameters. Plots of estimated mass loss over time are presented for different rock sizes and different levels of rock armour mobility.

Fish oil is a source of omega-3s, specifically EPA (Eicosapentaenoic acid) and DHA (Docosahexaenoic acid). These fatty acids play an important role for human health. Commercial fish oil production is increasing, but most of the products do not meet IFOS standards. This is a challenge for producers to produce standardized fish oil. The aim of this research was to identify and determining quality of softgel commercial fish oil in Central Java areas based on International Fish Oil Standards (IFOS). The method used was the treatment of differences in the area of origin of commercial fish oil purchases followed by testing the peroxide value, anisidine value, and total oxidation, fatty acid profile, and analysis of free fatty acids. The results showed that the percentage of free fatty acids, peroxide values, anisidine values, and total oxidation values that met IFOS standards were 37 % (3 of 8 samples), 17 % (1 of 8 samples), 83 % (7 of 8 samples) and 50 % (4 out of 8 samples). The best fish oil that fulfil all IFOS parameters has been the sample fish oil E from Tegal. Fish oil D from Tegal has the highest content of omega-3, EPA, and DHA, with values<br />of 83.65%, 56.57%, and 26.74% respectively.

Cooking oil is one of the essential ingredients of everyday life. Cooking oil is made from the mother's acid ester with glycerol. Cooking oil that is used repeatedly can harm health. The use of recurrent oil results in oil damage and affects the quality where the indicator of damage to cooking oil can be seen from the levels of free fatty acids and peroxides. To determine the effect of repeated frying on the quality of cooking oil in terms of the parameters of the levels of free fatty acids and peroxides. The research design used in this study is quantitative with experiments. The cooking oil used is bulk cooking oil and packaged cooking oil used to fry vegetable food ingredients, namely tofu. Numbers of peroxide and free fatty acids can be known through the titration method. The peroxide number test results have increased from the repetition of the third frying to branded oil and second repetition of bulk oil. Peroxide numbers obtained are higher than required by SNI (1.00 mg O2/100g). Examination of the levels of free fatty acids in samples of branded oil and bulk oil shows that all samples are by the oil quality requirements set by SNI (Max. 0.30% b/b).
