Sea resources that open access are causing competitive competition among fishermen. This mainly affects 87.5% of small-scale fishermen in Indonesia who are commonly in poverty. The problems faced are the marketing and production institutions that have not been optimal also the mindset of fishermen who are still subsistence. One way that small-scale fishermen try to increase their income is processing fresh fish to become smoked fish (traditional methode). The purpose of this study was to analyze the level of food security of small-scale fishermen household who also do smoked fish processing activities (NKPA) compared to small-scale fishermen household who did not undertake smoked fish processing (NKNPA). The sampling method uses multi stage cluster sampling. Data analysis used an analysis of food security using the Desirable Dietary Pattern. From the results of the study on the quantity aspect, overall AKE and AKP values in NKPA were 100.71% (good category) and 119.35% (the conditions were very food-resistant) while the NKNPA were 82.58% (moderate category) and 101.50 % (the conditions were very food-resistant). In terms of quality, the calculation of Desirable Dietary Pattern consumption from NKPA had a score of 88.49 and NKNPA of 71.77 which means that the conditions are quite ideal.

Abstract Organoleptic assessment of fresh fish includes specifications for the quality of the eyes, gills, mucus, odor, texture and flesh (color and appearance). However, not everyone has knowledge about it. This research uses the tiny yolov2 to facilitate the determination of fish freshness levels (good quality, medium quality, poor quality) correctly and fast. There are a few stages in this research, included organoleptic test accompanied by taking fish eye image dataset every hour, processing organoleptic test data labeling, training, and validation. There are three types of fish used, consists of Rastrelliger, Euthynnus affinis, and Chanos chanos. Detection of fish freshness level for three species was successfully carried out with the result of average precision is 72.9%, average recall is 57.5%, and accuracy is 57.5%. The factors that affect the prediction results in this study is the collection of datasets before the training process is carried out consisting of fish samples obtained from traditional markets, which are considered inadequate so that it affects the organoleptic test process itself, the organoleptic test that was carried out as a reference for image sorting was considered inaccurate because it used less than 30 untrained panelists and dataset imbalance.

The present study evaluated the microbiological, chemical, and organoleptic aspects of irradiated fresh fish and its products to extend their shelf life. Fresh fish and its products were irradiated at three doses (1.5, 3.0, and 4.5 kGy) used for preservation to study the effects of irradiation on their microbiological properties, fatty acid composition, and organoleptic properties. Irradiated fresh bolti fish, smoked herring, and smoked mackerel were evaluated microbiologically, chemically, and organoleptically. Radiation treatment not only reduced the counts of aerobic bacteria, fecal streptococci, molds, and yeasts but also destroyed all the Staphylococcus aureus cells, improving the hygienic quality of the fresh and smoked fish samples. Irradiation increased the peroxide, acid, and thiobarbituric acid values, but they remained within acceptable levels. No new fatty acids or other artifacts due to irradiation were observed. Irradiation of 4.5 kGy greatly reduced the organoleptic quality scores of fresh bolti fish, indicating that the optimum radiation dose for this fish was 3.0 kGy. Smoked herring and mackerel could be irradiated with up to 4.5 kGy without adverse effects on their organoleptic properties.

The purpose of the study was to evaluate the relationship between the provision of food to public primary schools by FTC and the enrolment of pupils in Mara Ward of Narok West Sub-County, Narok County, Kenya. The study adopted descriptive survey research design. The target population was 131 public primary schools in Narok West Sub-County, 1460 teachers and 3150 pupils. A sample of 97 schools, 302 teachers and 344 pupils was drawn. Simple random sampling method in the numbers of schools, teachers and pupils was used. Findings of the study showed that provision of food increased the enrolment rate of pupils in school. This is because meals programmes offered in schools enables the pupils from far and humble backgrounds to have similar treatment to the pupils coming from better backgrounds and close to the schools. These programmes increased the level of admission of new pupils thus increasing the rate of enrolment in most schools. However, offering food in schools does not automatically increase the rate of enrolment for it was realized that quality of food matters the most as well. The findings can help the government to sensitize on the quality of food being offered to be increased. Meals programmes should be implemented in all schools in Mara Ward and even to other parts of the country. In addition, the quality of the food offered should be increased to reduce diseases associated with malnutrition.

Seaweed flour is a potential source of dietary fiber expected to improve the quality of fishery products. The purpose of this study was to determine the effect of addition of seaweed flour (Eucheuma sp.) on the quality and characteristics of tuna fish amplang. The research method was using a non-factorial completely randomized design (CRD) consisting of five treatments of varied amount of seaweed flour added (0, 0.5%, 1%, 1.5%, and 2% from the total dough weight). The variables to assess the quality were the organoleptic quality and characteristics (appearance, aroma, taste and texture), swelling degree, and proximate content. The results showed that the addition of seaweed flour can improve the proximate composition of fish amplang, especially the increase in crude fiber content. The addition of seaweed flour has an optimum concentration point of 1% to produce the best tuna fish amplang with the characteristic of bright colors, clean, smooth surface, not cracked, savory taste and a crunchy and dense texture. The score of the appearance was 8.3; aroma was 7.7, taste 8.2, texture 8.5, and the swelling degree was 384%. The best product was containing water 1.14%, ash 3.82%, protein 39.59%, fat 12.92%, and fiber 5.79%.

The purpose of this study was to determine how long the tuna smoking process takes and how long the quality of smoked fish lasts by conducting an organoleptic test. The material of this research is the organoleptic test of smoked tuna quality with the Efhilink fish fumigant and the simple cabinet type on smoking time. The method used in this study is an experimental method that is by using corn clams as fuel for smoking cobs. The conclusion of the different treatment of the Efhilink and the simple cabinet type with the analysis results can be seen that the fumigation process that is the fastest produced by the Efhilink rack 1 type fumigator is 56 minutes. This is because the working process of the Efhilink type smoker changes the shape of the smoke produced into liquid smoke by connecting the smoke pipe with the condenser so that the temperature of the Efhilink device can be hotter than the Simple Cabinet-type fumigator, besides that the position of rack 1 is very close to the smoke source. . Whereas the longest smoking process produced by a Simple Cabinet Type 3 rack smoking device is 325 minutes or 5 hours 25 minutes this is due to the working process of the Simple Cabinet Type smoking device which emits the smoke produced through the top funnel, so that the heat produced is lower. than the Efhilink-type fumigator. In addition, the position of shelf 3 is very far from the smoke source. Meanwhile, the best organoleptic test value was produced on day 3 of the two tools. Based on the results of the study, it is suggested that the fumigation process uses the Efhilink smoke device.
