Abstract

Feed is the largest contributor to operational costs (50-60%) in intensive vaname shrimp (Litopenaeus vannamei) cultivation, so inefficient feed management can substantially erode profitability. This case study aims to analyze the technical and economic impact of the implementation of an Automatic Shrimp Feeder (ASF) integrated with Internet of Things (IoT) technology and powered by solar energy on PT's intensive shrimp ponds. Mina Balng Berkah, Sukabumi. The research uses mixed methods with qualitative descriptive analysis. The results show that ASF adoption has a significant positive impact. Feed efficiency increased sharply, as indicated by a decrease in the Feed Conversion Ratio (FCR) from 1.5 to 1.25. Apart from that, the use of ASF also has an impact on increasing the Survival Rate (SR) and cultivation productivity. From an economic aspect, feed efficiency and reduced labor requirements for feeding (from 3 to 2 people per cycle) result in reduced operational costs and increased production value, which leads to an increase in net profitability of more than twofold. The application of ASF based on IoT and solar energy has proven to be the optimal solution for achieving precision aquaculture, increasing resource efficiency, and being effective in increasing the productivity and sustainability of shrimp farming.

Abstract

Blue swimming crab (Portunus spp.) is a high-value demersal fishery commodity in Indonesia, yet increasing fishing pressure threatens its stock sustainability. This study aims to analyze the utilization level, determine optimum effort, and estimate economic rent of blue swimming crab fisheries at Karangantu Fishing Port, Banten within Fisheries Management Area 712. A bioeconomic approach using the Clark-Yoshimoto-Pooley (CYP) algorithm was applied to time-series data from 2015-2024. Results showed Biological parameter estimation yielded intrinsic growth rate (r) = 8.54/year, catchability coefficient (q) = 0.00053, and environmental carrying capacity (K) = 30.94 tons. Bioeconomic analysis revealed that actual conditions (production 86.5 tons, effort 12,283 trips, profit IDR 1,055 million) have exceeded the optimum level. The Maximum Economic Yield (MEY) regime offers the most optimal scenario with production of 58.8 tons, effort of 5,396 trips, biomass of 20.6 tons, and profit of IDR 1,573 million, increasing profit by 49% through 56% effort reduction. Total Allowable Catch (TAC) was set at 52.86 tons (80% of MSY), with quota allocation: set gill nets (45.20 tons), bottom trawls/dogol (3.87 tons), and pots/traps (3.79 tons). Policy recommendations include effort reduction towards 5,000-6,000 trips/year and implementation of input-output controls for sustainable blue swimming crab management in WPP 712.

Abstract

Increasing fishing pressure can lead to an imbalance between exploitation rates and the carrying capacity of fishery resources. Globally, more than 30% of fish stocks are overfished, while most others are fully exploited. At the national level, Fisheries Management Area of Indonesia (WPP-NRI) 572, covering the Sunda Strait and Lampung waters, has an estimated potential of 1.22 million tons per year, with most pelagic stocks already fully to over-exploited. Indications of excessive fishing pressure are reflected in declining catch per unit effort (CPUE) and the capture of fish below their length at first maturity. These conditions may lead to stock degradation, reduced fishery productivity, and long-term economic losses for local fishers in Tanggamus Bay. This study aims to evaluate the utilization of pelagic fishery resources in Semangka Bay following the establishment of a fisheries conservation area. A bioeconomic analysis using the Fox model was applied, based on data collected from 55 fishers in October 2024. The estimated parameters include intrinsic growth rate (r = 0.388), catchability coefficient (q = 0.000086), and environmental carrying capacity (K = 212,234.135 tons per year). The results indicate that the optimal effort at Maximum Sustainable Yield (MSY) is 2,263 trips per year, producing 20,614.67 tons, while at Maximum Economic Yield (MEY) the optimal effort is 2,260 trips per year, yielding 20,614.63 tons with an economic rent of 516,157 million rupiah. However, during 2015–2023, actual fishing effort exceeded both biological and economic optimum levels, indicating overfishing. Therefore, quota-based management through the implementation of Total Allowable Catch (TAC) and effort control is recommended to ensure the sustainability of pelagic fishery resources.

Abstract

The high demand for shrimp in the global market, along with national production growth targets, requires continuous improvement in shrimp pond productivity. However, production performance at the farm level remains suboptimal due to limitations in operational management, particularly in feeding systems that are still largely carried out manually. This condition highlights the need for technological adoption to support more optimal production performance in shrimp farming. This study aims to examine efforts to increase the productivity of intensively cultivated whiteleg shrimp brackish ponds (Litopenaeus vannamei) owned by PT Mina Balong Berkah through the use of shrimp feeders, a device that can automatically provide feed. The study was conducted using qualitative and simple quantitative to compare shrimp production performance, water quality, and farmer experience from ponds using shrimp feeders with ponds where feeding is done manually. The results obtained showed that the production performance of ponds using shrimp feeders was higher than that of ponds where feeding was done manually. Average Daily Growth (ADG) of shrimp feeder ponds was 0.2 and 0.22 g/day, while manual ponds were 0.18 and 0.19 g/day. Average Body Weight (ABW) of shrimp feeder ponds was 15.84 and 14.39g/head, while manual ponds were 13.44 and 14 g/head. Survival Rate(SR) of shrimp feeder ponds was 78.1 and 84.2%, while manual ponds were 69.9 and 72.3%. The Feed Conversion Ratio(FCR) of shrimp feeder ponds was 1.48 and 1.6, while that of manual ponds was 1.71 and 1.79. The productivity of shrimp feeder ponds was 36.58 and 38.21 tons/ha, respectively, while that of manual ponds was 30.59 and 31.94 tons/ha. Based on these results, shrimp feeders have the potential to be used as a support for increasing shrimp cultivation intensification in Indonesia.

Abstract

Time efficiency in longline operations is a crucial factor in improving productivity, reducing operational costs, and maintaining the catch quality in tuna fisheries in the Indian Ocean. However, time management at each stage of the fishing operation has not been systematically measured, potentially leading to inefficiencies. This study aims to identify the stages of longline operations on the KM Permata 99 and analyze the time distribution of each activity using the Critical Path Method (CPM). The study was conducted from January–April 2024 in the Indian Ocean waters with a fishing base at Benoa Harbor, Bali. Longline operations consist of 28 activities divided into two main stages: the preparation stage (7 activities) with a total time of 80 minutes and the operation stage (21 activities) with a total time of 1,400 minutes. Based on the Critical Path Method (CPM) analysis, the total time of one operating cycle is 1,480 minutes or equivalent to 24.6 hours per daily trip. All activities are on the critical path with a total float (TF) value of zero, so that delays in one activity will directly impact the entire process. Increasing the number of crew members from an average of 18 to 25 was found to improve operational efficiency. These findings highlight  the importance for Critical Path Method (CPM) based operational time standardization and optimization of the number and division of labor of crew members as part of fishing vessel operational management. This policy has the potential to increase business efficiency, reduce costs, and support sustainable fishing practices.

Abstract

The low protein content of traditional carbohydrate-based foods such as tiwul, along with the increasing demand for nutritious, practical, and locally sourced alternative foods, has become a significant concern. In addition, the utilization of fisheries by-products such as small shrimp (rebon) through protein hydrolysate technology presents substantial potential as a functional protein source that has not yet been optimally exploited. Therefore, this study aims to determine the effect of rebon shrimp protein hydrolysate fortification on the organoleptic quality and nutritional content of instant tiwul, as well as to identify the optimal fortification concentration. The study employed an experimental method using a non-factorial Completely Randomized Design (CRD) consisting of four treatment levels of rebon shrimp protein hydrolysate concentration, namely 0%, 5%, 10%, and 15%, each with three replications. The observed parameters included organoleptic tests (appearance, aroma, texture, and taste) and proximate analysis (moisture, ash, protein, fat, and carbohydrate content). testttttt

Abstract

The use of various types of sweeteners in herbal drinks is a strategy to increase consumer acceptance, especially for mangrove-based tea products that are rich in bioactives but have a tart taste and distinctive aroma. This study aims to analyze the effect of four types of sweeteners: white sugar, palm sugar, palm sugar, and honey on the physical characteristics and consumer preference levels for mangrove tea, while also determining the best treatment. The study was conducted using a formulation of 3 g of mangrove leaf powder brewed with 200 mL of water and added sweeteners according to the treatment, then tested for pH, color (L*, a*, b*), viscosity, total titratable acid, total sugar, and a hedonic test by 30 untrained panelists. The results showed that honey had the greatest effect on physical aspects, marked by the lowest pH (6.62), the highest viscosity (1.32 mPa·s), and the darkest color with an increase in the a* and b* components. Palm sugar and palm sugar produced caramel color characters due to the Maillard component, while white sugar showed the most neutral character in all parameters.The hedonic test showed that palm sugar obtained the highest scores in the attributes of taste (8.3±0.8), color (7.9±0.8), appearance (8.0±0.8), aroma (8.1±0.7), and overall (7.2±0.8), while white sugar had the lowest scores with values of taste (6.8±0.9), color (6.5±1.0), appearance (6.9±0.9), aroma (7.0±0.8), and overall (6.1±0.9). The type of sweetener was proven to have a significant influence on physical quality and consumer preferences. The most effective treatment in improving the sensory quality of mangrove tea was the use of palm sugar.

Abstract

Nypa palm is one of the mangrove commodities widely distributed in Indonesia. Nypa fruit has the potential to be used as a food ingredient, one of which is flour. This study aims to examine the characteristics of nypa fruit flour produced from nypa fruit with different levels of maturity, namely young ripeness (NM), medium ripeness (NS), and old ripeness (NT). This study used an experimental method using a Completely Randomized Design (CRD) design. The parameters observed included organoleptic, proximate, and dietary fiber. The highest yield of whole fruit was obtained at NT, namely 30.13%. The highest flour yield was obtained at NS at 86.97%. The results of the hedonic test showed the highest values for color, aroma, and texture parameters were obtained at NS. The highest water content was obtained at NM at 7.89% and the lowest at NT at 4.72%. The highest ash was obtained at NM at 3.10% and the lowest at NT at 1.61%. The highest protein was found at NT at 8.70% and the lowest was found at NM at 5.80%. The highest dietary fiber content was found in NT (20.94%), and the lowest in NM (11.89%). Generally, the best flour is obtained from medium ripeness (NS) nypa However, when referring to the SNI for wheat flour (SNI 3751:2018), tapioca flour (SNI 3542:2011), and cornstarch flour (SNI 3727:2020), the ash content parameter does not meet the maximum threshold.

Abstract

Herbal coffee based on local natural ingredients has the potential to become a functional beverage innovation with high nutritional and bioactive value. This study aimed to formulate and evaluate the physical, chemical, and sensory characteristics of mangrove herbal coffee (Avicennia marina) using four types of natural sweeteners: palm sugar (GS), coconut sugar(GA), honey (GM), and refined sugar(GP). The herbal coffee powder was prepared from A. marina fruit through soaking, drying, and roasting at 120–150°C, followed by blending with each sweetener formulation. Analyses included physical parameters (color, solubility, moisture content, bulk density), chemical composition (total phenolics, total sugar, pH), proximate composition (carbohydrate, protein, fat, and energy), and sensory evaluation using a 9-point hedonic scale. The results indicated that sweetener type significantly affected product quality. The palm sugar formulation showed the highest total phenolic content (16.87 mg GAE/g) and the most balanced taste, whereas the honey formulation had the highest total sugar and energy values (34.77 g/100 g; 191.7 kcal/100 g). Sensory evaluation revealed that mangrove coffee with palm sugar and coconut sugar achieved the highest preference scores for color, aroma, and taste (mean scores 7.2–7.4). Formulations with palm-based sweeteners exhibited the best balance between physical quality, bioactive content, and consumer acceptability. This study highlights the potential of A. marina as an innovative local raw material for functional beverage development that supports sustainable utilization of coastal resources.
