Abstract

Mackerel (Scomberomorus sp.) is a fishery commodity widely consumed by the public due to its high nutritional value and important economic value. However, fishery products have a high potential for contamination by heavy metals such as lead (Pb) and cadmium (Cd) originating from aquatic environmental pollution. This study aims to analyze the content of heavy metals lead (Pb) and cadmium (Cd) in mackerel and evaluate the level of food safety based on SNI 2354.5:2011. The research method was carried out by laboratory tests using instrumentation methods (AAS). The results showed that the lead (Pb) levels in the samples ranged from 0.000–0.176 mg/kg, while the cadmium (Cd) levels ranged from 0.031–0.047 mg/kg. All values ​​obtained were still below the maximum limits set, which are 0.3 mg/kg for lead (Pb) and 0.05–0.1 mg/kg for cadmium (Cd). Variations in heavy metal levels between samples are influenced by environmental and biological factors such as fishing location and fish size. Based on these results, it can be concluded that the mackerel tested still meets food safety requirements and is safe for consumption within reasonable limits.

Abstract

Tuna is a fishery commodity that is very susceptible to increased histamine levels because it belongs to the Scombridae family of fish that naturally have high histidine levels. Histamine is formed through bacterial enzymatic activity during handling and storage at inappropriate temperatures. This study aims to examine the technique of testing histamine levels in tuna (Thunnus sp.) circulating in Makassar, South Sulawesi, as an indicator of product quality and safety. The method used is quantitative descriptive analysis with High Performance Liquid Chromatography (HPLC) techniques that refer to the ISO 19343:2017 standard. The analysis procedure includes sample preparation, extraction using perchloric acid, derivatization with dansyl chloride, and purification before measurement using a UV detector at a wavelength of 254 nm. This technique was chosen because it has high sensitivity, selectivity, and accuracy in detecting histamine at low concentrations. The test results showed that histamine levels in the analyzed samples were in the range of 13.55 mg/kg to 48.78 mg/kg. This value is still below the maximum threshold of 100 mg/kg set in SNI 2729:2013, thus the product is declared safe for consumption. However, variations in histamine levels between samples indicate differences in post-harvest handling and distribution. Therefore, consistent implementation of a cold chain system and good handling practices are key factors in maintaining the quality and ensuring the safety of fishery products in the region.

Abstract

The climbing perch (Anabas testudineus) is a local freshwater fish with high economic value and strong adaptability to aquatic environments. The success of climbing perch culture is influenced by rearing conditions, particularly water source and water depth. Differences in water source characteristics and rearing water depth are presumed to affect water quality, growth, and fish survival. This study aimed to analyze the effects of water source, rearing water depth, and their interaction on the growth and survival of climbing perch (Anabas testudineus). The research was conducted in Murung Raya Village, South Banjarmasin District, Banjarmasin City, South Kalimantan Province, for 60 days. An experimental method using a 2 × 3 factorial Completely Randomized Design (CRD) with three replications was applied. The first factor was water source, consisting of tap water (A1) and river water (A2), while the second factor was water depth, consisting of 20 cm (B1), 30 cm (B2), and 40 cm (B3). A total of 270 climbing perch fingerlings measuring 3–5 cm were reared in tarpaulin ponds. Observed parameters included absolute weight gain, absolute length gain, survival rate (SR), and water quality parameters consisting of temperature, pH, dissolved oxygen (DO), and ammonia (NH₃-N). Data were analyzed using analysis of variance (ANOVA). The results showed that water source and rearing water depth had no significant effect on the weight gain and length gain of climbing perch at the 5% significance level (P > 0.05), although differences in mean values among treatments were observed. Water quality parameters remained within acceptable ranges for fish survival. It can be concluded that the use of different water sources and water depths can support the culture of climbing perch in household-scale tarpaulin pond systems.

Abstract

Male guppies Poecilia reticulata are more valuable than females because of their brighter coloration and greater market demand. The use of natural compounds for sex reversal has attracted increasing attention as a safer alternative to synthetic hormones. This study evaluated the effectiveness of celery Apium graveolens powder immersion on male sex ratio and larval survival of guppies. A completely randomized design was applied with four treatments and three replicates, consisting of a control (without immersion) and immersion in celery powder solutions at concentrations of 5, 10, and 15 mg L⁻¹ for 8 h. The larvae were reared for 45 days. The observed parameters included male sex ratio, survival rate, and water quality. Immersion in celery powder significantly affected the male sex ratio (P<0.05), whereas no significant effect was observed on larval survival (P>0.05). The highest proportion of males was obtained at 15 mg L⁻¹, reaching 63.33 ± 1.15%, while the control produced 23.33 ± 1.53% males. Larval survival remained high, ranging from 86 to 100%, and water quality was maintained within the optimal range throughout the experiment. These findings indicate that immersion of guppy larvae in 15 mg L⁻¹ celery powder for 8 h increased the proportion of males without compromising larval survival, suggesting that celery powder is a promising natural alternative for guppy masculinization.

Abstract

This study aimed to analyze the effect of different feeding-day schedules on the culture performance and business feasibility of red tilapia (Oreochromis niloticus). The experiment was conducted for 30 days using a Completely Randomized Design (CRD) consisting of three treatments and four replications, namely A (daily feeding), B (6 days of feeding followed by 1 day of fasting), and C (7 days of feeding followed by 1 day of fasting). The observed parameters included Survival Rate (SR), weight gain, length gain, Specific Growth Rate (SGR), Feed Conversion Ratio (FCR), Feed Utilization Efficiency (FUE), water quality, and business feasibility analysis, including profit, Break-Even Point (BEP), Revenue-Cost Ratio (R/C), Cost of Production (COP), and Payback Period (PP). Data were analyzed using Analysis of Variance (ANOVA) at a 95% confidence level. The results showed that different feeding-day schedules had no significant effect (P>0.05) on SR, weight gain, length gain, SGR, FCR, and FUE. Descriptively, treatment C produced the best growth performance, while the highest survival rate was observed in treatment B. Water quality remained within the optimum range throughout the study, with temperatures ranging from 27.83 to 28.00°C and pH values ranging from 7.82 to 7.89. The business feasibility analysis indicated that treatment B was the most feasible treatment, generating a profit of IDR 132,657.80, an R/C ratio of 1.11, a break-even point of IDR 652,271.67 or 65 fish, a production cost of IDR 8,995.02 per fish, and a payback period of 3.11 years. It can be concluded that different feeding-day schedules did not significantly affect the culture performance of red tilapia. However, the feeding regime of six consecutive feeding days followed by one fasting day provided better business feasibility than the other treatments

Abstract

This study aimed to determine the optimal formulation of carrageenan powder addition in tilapia (Oreochromis niloticus) nuggets to produce the product most preferred by panelists. An experimental method was employed with four treatment levels of carrageenan powder addition: 0%, 0.5%, 1%, and 1.5%. The parameters observed included hedonic preference levels (appearance, aroma, texture, and taste) and the fold test across all treatments. Chemical analyses—comprising moisture, protein, ash, carbohydrate, and fat contents—were conducted on the control treatment (0%) and the most preferred treatment based on organoleptic results. Sensory evaluations were performed by 20 semi-trained panelists and analyzed using the Friedman test, followed by a multiple comparison test where significant differences occurred. Fold test data were analyzed using the Kruskal–Wallis test, whereas the best treatment was determined using the Bayes method. The results indicated that the 1% carrageenan powder addition was the most preferred treatment by the panelists, yielding mean preference scores of 7.9 for appearance, 7.2 for aroma, 8.2 for taste, and 8.1 for texture. Chemical analysis of this treatment revealed a moisture content of 48.13%, ash content of 5.35%, fat content of 8.27%, protein content of 21.23%, and carbohydrate content of 17.02%. The fold test yielded average values ranging from 4.0 to 4.5, corresponding to Grade A (elastic texture). Keywords: Tilapia, carragenan, nugget, organoleptic

Abstract

Narrow-barred anchovy (Stolephorus spp.) is one of the important fishery commodities in Sumenep Regency and has considerable potential as a nutritious food source due to its high protein and mineral contents. Processing anchovies into fish flour can increase their economic value and expand their utilization as a functional food (superfood). The quality of fish flour is strongly influenced by the cooking method applied prior to drying. This study aimed to evaluate the effect of different cooking methods on the yield, moisture content, ash content, and calcium content of anchovy flour and to determine the most suitable processing method. A completely randomized design (CRD) with three treatments was employed, namely no cooking (C), boiling at approximately 100°C for 5 minutes (R), and steaming at approximately 100°C for 5 minutes (K), each with three replications. Data were analyzed using one-way analysis of variance (ANOVA) at a 95% confidence level followed by Duncan's Multiple Range Test (DMRT) when significant differences occurred. The results indicated that cooking methods significantly affected yield (p=0.040), moisture content (p<0.001), and ash content (p<0.001), but had no significant effect on calcium content (p=0.076). Boiling produced the highest yield (14.97±0.15%) and the lowest moisture content (8.84±0.03%), whereas the untreated samples had the highest ash content (9.96±0.03%) and calcium content (79.00±9.00 mg/100 g). These findings suggest that boiling is the most effective pretreatment for producing anchovy flour with desirable physical characteristics, while calcium content remains relatively stable regardless of the cooking method.

Abstract

Dodol is a semi-moist food product susceptible to quality deterioration during storage; therefore, packaging capable of maintaining product quality is required. This study aimed to analyze the quality and shelf life of dodol packaged using edible film made from *Kappaphycus alvarezii*, woka leaves, and a combination of both. A factorial Completely Randomized Design (CRD) was employed with two factors: packaging type (edible film, woka leaves, and a combination of edible film and woka leaves) and storage duration (0, 7, 14, and 21 days at room temperature). Observed parameters included fat content, Thiobarbituric Acid (TBA) value, and organoleptic characteristics (color, aroma, taste, and texture). Fat content and TBA value data were analyzed using Analysis of Variance (ANOVA), while organoleptic data were analyzed using the Kruskal–Wallis test, followed by the Dunn test if significant differences were found. ANOVA results indicated that fat content was not significantly affected by packaging type, storage duration, or their interaction (P>0.05). Conversely, TBA values ​​increased during storage and were significantly influenced by packaging type, storage duration, and their interaction (P<0.05). Kruskal–Wallis test results showed that packaging treatment and storage duration significantly affected organoleptic characteristics—color, aroma, taste, and texture (P<0.05)—with differences between treatments further identified via the Dunn test. Edible film packaging resulted in lower TBA values ​​and better maintained panelists' preference for organoleptic characteristics compared to woka leaf packaging and the combination of both. Based on chemical and organoleptic parameters, the use of edible film made from *Kappaphycus alvarezii* maintained dodol quality for up to 14 days of storage at room temperature. Thus, edible film made from *Kappaphycus alvarezii* has the potential to serve as an alternative packaging method to maintain quality and extend the shelf life of dodol.
