Abstract

The development of seaweed cultivation by farmers cannot be separated from production factors such as capital, seeds, labor, and land area, which greatly support the success of seaweed cultivation. This study aims to analyze the factors affecting seaweed production and how to return to scale. The research was conducted in Pantai Amal Village. The number of samples in the study was 59 seaweed farmers using the incidental sampling method. The data analysis technique used multiple linear regression analysis in the form of the Cobb-Douglas function logarithm using the SPSS 26 software. The results showed that simultaneously the capital factors (X1), seeds (X2), labor (X3), and land area (X4) jointly affect the production (sig=0.00). Only the farmer's capital partially showed a significant effect (0.00) smaller than the significance level of = 0.05. The business scale has shown increasing returns to scale with a coefficient value of 1.15, which means that all inputs used in production are increased by 1. The resulting production will be increased by 1, and the resulting production will increase by a more significant proportion, namely 1.15. Thus, seaweed farmers’ use of production factors is efficient

Abstract

As much as 90% of the fisheries industry in Dumai City comes from capture fisheries. The capture fisheries industry is a crucial industry that requires more attention from the government because of its enormous potential. Every year, there is a decrease in the number of fishing households in Dumai City. The reason is the uncertainty of income received and the existence of other business sectors. Fishing communities depend on fisheries resources for their livelihoods. However, the fishing profession in Dumai City is susceptible to changes around it, including changes due to the development of the CPO industry. This study was conducted to analyze the economic impact of the CPO Industry's development on the Lubuk Gaung Village fishing community. This research uses a quantitative survey method, followed by quantitative descriptive data analysis and hypothesis testing with a paired sample t-test.

Abstract

Spirulina sp is one of the organisms used because it has twice the chlorophyll content of the alfalfa plant, the chlorophyll of which has previously been explored. Chlorophyll-a is a photosynthetic pigment, and light is very influential in photosynthesis in microalgae cultivation because light is a crucial part of the photosynthetic pigment as a source of energy for microalgae life. The purpose of this research is to get the best light intensity. This research started in September 2022 at the Aquaculture Environmental Quality Laboratory, Faculty of Fisheries and Marine, Universitas Riau. This study used a one-factor, Completely Randomized Design (CRD) method with five treatments and three replications. The treatment in this study was the light intensity consisting of P0: without giving light, P1: 2.974 lux, P2: 4.274 lux, P3: 5.575 lux, P4: 6.877 lux. The results of this study indicate that light intensity affects the locking of Spirulina sp. The best treatment was a light intensity of 4.274 lux with a cell density of 327.176,2 ind/mL with a chlorophyll-a content of 0.4 µg/mL with a range of water quality parameters that were optimal for the growth of Spirulina sp temperature value 28-31, pH 7-8.5, DO 5-7.5

Abstract

This study aims to determine the perceptions of local communities towards marine sand mining activities in the Kepulauan Riau Province. Considering the region's dominance, Kepulauan Riau has great potential for sand mining in terms of quality and quantity. The population dynamics and high development today encourage an increased need for sand. Therefore, sand mining businesses have become social, economic, and ecological. This research uses a descriptive qualitative approach with an interview method with 60 respondents. Multiple linear regression analysis was used to predict perceptions based on social, economic, and ecological variables. The results showed that social aspects (coefficient value of 0.809) strongly influenced the sustainability of mining activities compared to ecological aspects (0.271) and economic aspects (-0.045). This finding shows that if mining activities can create good social conditions in local communities, sand mining activities can continue. However, these social conditions are related to the ecological impacts caused by mining
