Abstract

Shredded meat milkfish is one of fishery products made from steamed milk fish meat, making meat, seasoning, frying  and squeeze that will produce shredded meat. This study aimed to identification of the waste types and the application of the  zero waste concept in the processing of milkfish shredded meat in Shefish business group located at  Bumi Agung 1 Residence Serang Banten Province.   In the process of making milk fish shredded meat waste is generated in the form of liquid and solid wastes. Liquid wastes include water fish washing results, steaming water and the juice of the fish meat. While the solid waste generated from the gills, guts, fish heads, skin and fins of fish, fish bones and condiments such as leather waste of onions and garlic skins.  The application of zero waste concept through waste utilization optimizing the milkfish shredded meat  processing can be done either on liquid and solid wastes. Utilization of liquid wastes such as water washing and boiling water containing soluble protein can be used as an ingredient in  feed ducks pasta  and flavor products. Utilization of solid wastes in the form of fish bones and spines can be used to fish bone meal, fish head waste can be processed into crackers calcium, and use of the intestines and gills can be used as raw fish silage or bekasang product.  Milkfish skins and spins becomes to crispy product.  Waste generated in the milkfish shredded meat processing of Shefish business groups are  used yet. The application of  zero waste concept by optimizing the utilization of waste is one of the effective and efficient solutions to prevent in the fish processing waste.Keywords:  milkfish shredded meat, zero waste, waste, optimizing

Abstract

Leaftail croaker fish (Johnius sp) is one of less economically important demersal bycatch, abundant yet underutilized. Efforts to increase the economic value into surimi product, since it has tender, white and thick texture of meat. As an important factor in surimi production process, this study aimed effects of different leaching frequency on chemical and physical characteristics of product in order to obtain its optimum frequency. Completely randomized design was used with 3 different leaching frequency and 3 repetitions. Further, each sample were analysed chemically using proximate analysis (water content, protein content and fat content) and physically using sensory analysis (folding and cutting test). Statistical non parametric Kruskal Wallis test was conducted to have significance level of folding and cutting test. More leaching frequency increases water content value, but decrease protein and fat content value in surimi. Statistical analysis suggested that optimum characteristics of surimi resulted from 2 times leaching with water content of 82.61%, protein content of 15.58% and fat content of 0.36%. Although, sensory analysis showed that leaching frequency positively correlated to the value of folding and cutting test, 2 times leaching was also optimum for surimi production process.

Abstract

Sumenep is one of Madura's regency, which has many islands with a wealth and diversity of natural resources, especially in its marine and coastal areas. With many islands owned, sea transportation in Sumenep is of great importance in the regency. One of the crucial aspects that must be considered related to this transportation is tidal information. This study aims to determine the tidal characteristics in the South and North Coast of Sumenep Regency using the Least Square method. The tide data used in February and September 2020 were obtained from the Geospatial Information Agency (BIG) with an observation interval of one hour. This time was chosen because it represents monsoons' occurrence in Indonesia in the annual season, namely the dry and rainy seasons. The results of this study indicate that the southern coastal area (Giligenting District) has a mixed tidal type, tends to be semi-diurnal with Formzahl numbers of 0.86 and 1.29 (0.25 <F £ 1.5). In comparison, the North coast (Dasuk District) has a Diurnal tidal type with Formzahl numbers of 3.64 and 4.30 (F > 3.0). The different tides are due to the sampling's location representing different geographical conditions, namely open waters (North Coast) and closed waters (Pesisir Selatan). The elevation parameters obtained still need supporting data such as waves, currents, and bathymetry used by policymakers for safety in using sea transportation.

Abstract

The highest fish production in Labuan Coastal Fishing Port (LCFP) is mackerel tuna which reached 41,953 ton (22.1%) of total production. Mackerel tuna is economical and perishable commodity. Therefore, it requires a good marketing chain to maintain its quality. The purpose of this research is to determine the marketing chain of mackerel tuna landed at LCFP; determine the marketing margins of each marketing agent; and analyze the quality of mackerel tuna from unloading ship to the consumer. This research was conducted in March-April 2019 at LCFP. This study used the survey method. While the methods used for quality testing of tuna are sensory (visual observations) or by organoleptic tests by parameters in the form of eye conditions, gills, meat and odor texture of fresh fish standards using a score sheet based on BSN. Checking the quality of fish is done at every marketing chain. Data analysis was carried out descriptively. The result show that there are four types of marketing chains in LCFP. The highest marketing margin obtained by outside trades (IDR 5,000 or 20%) on the fourth channel and the lowest margin sales obtained by main collectors on the second and third channels (IDR 2,000 or 8%). The longer the marketing chain, the lower the quality of mackerel tuna.

Abstract

The combination of natural ingredients derived from the sea and land for cosmetics has not been done much. Natural ingredients that are known to have good properties for the skin are jicama and seaweed so the objective of this study was to formulate seaweed (Kappaphycus alvarezii) and jicama (Pachyrhizus erosus) as a body lotion. The objective in this study was to determine the best body lotion preparations from seaweed (K. alvarezii) and jicama (P. erosus). The combination of seaweed and jicama as much as 15% with the formulation of seaweed and jicama were F1 (1:2), F2 (1:1), and F3 (2:1) with Completely Randomized Design, respectively. Organoleptic test results from body lotion including aroma, color, texture, and absorption in all treatments were not significantly different, except in controls. In all treatments, the type of emulsions was O/W and homogeneous. The pH values at F0, F1, F2, and F3 were 7.82; 7.97; 8.04 and 8.09. The viscosity test results found that the best treatment was F1 (16,941 cPs), while for antioxidant activity was the F3 treatment (1,656 µg/ml). Based on antioxidant performance, it was best to treat F3 for body lotion from K. alvarezii seaweed and jicama powder.

Abstract

Secchi disk has long been used as a measure of water transparency because of its simplicity. Brightness is a portion of the light transmitted into the water. This study examines the differences in the brightness of the water with a combination of black and white case study in the Ciwaka reservoir, Walantaka, Serang – Banten Province. The study was conducted in May 2015. The observation point are in the inlet, middle and outlet area. Observations secchi brightness using four different colors: black (Hi), white (Pu), 2 black-and-white shaded (A2) and 4 shaded black-and-white (A4). The experimental design used was completely randomized factorial design with color factor secchi and observation points. Secchi disk affect the value of color brightness or Secchi depth, a good color to use for the waters of the reservoir is a combination of black and white either 2 or 4 shaded. The central region and the outlet has a low brightness value, this is due to the accumulation of organic and inorganic materials in the region.
