Mini trawl fishing gear has a positive impact as a source of livelihood, but it also has a negative impact on marine biodiversity due to its non-selective nature. This condition requires wise management of aquatic resources in maintaining the sustainability of the marine ecosystem, especially in the waters of Kampung Nelayan Village. The purpose of this study is to determine the diversity of catches in Mini Trawl fishing gear (Mini bottom trawl) in Kampung Nelayan Village, Tungkal Ilir District, Tanjung Jabung Barat Regency. The research method used is the survey method, a method of determining respondents using simple random sampling of 10% from 50 people to 5 fishermen for 10 arrests. The data analysis used was the Diversity Index, Uniformity Index and Dominance Index. The results of the study were obtained that the diversity index value of 3.19 was included in the high category (H'>3), the uniformity index of 1.06 was included in the high category (E>0.6), and the dominance index of 0.06 was included in the low category (C'<0.4). The conclusion of this study is that the value of the diversity index is high, uniformity is high and no species dominate

Plastic in the aquatic environment poses a new problem, namely microplastics. Microplastics are widespread in marine waters and sediments. Seawater has been widely used by humans, one of which is as raw water for making salt, but the presence of microplastics in marine waters is feared to affect the quality of salt production. The aim of this study was to analyze water quality and identify the quantity and type of microplastic polymers in raw water sources of salt ponds and sediments in Pamekasan. Water quality data for pH, temperature, and DO in Pamekasan salt ponds were in the ranges of 7.5 ± 0.02 - 7.8 ± 0.02; 29.3 ± 0.03 - 31.9 ± 0.09 °C; 6.83 ± 0.26 - 9.42 ± 0.21 mg/L. Microplastics found in salt pond raw water reached 2.06-3.32 particles / L. Microplastics found in sediments were 2,65 ± 0,14 partikel/L and 0,82 ± 0,02 particles/gram. The forms of microplastics found are fibers, fragments, and films. The microplastics in water and sediments influence as much as 44,58% or quite significantly. The types of polymers found in the samples are Polypropylene (PP), Polyethylene (PE), Polyamide (PA), and Low-Density Polyethylene (LDPE).

Kuri Beach Tourism Nisombalia Village has great potential in attracting tourists, management and development. Management that does not pay attention to the carrying capacity aspect of the area causes environmental quality to decrease, this is the main attraction. This study aims to assess the land suitability and carrying capacity of Kuri Beach tourism in Nisombalia Village, Marusu District, Maros Regency, South Sulawesi. The research method employed land suitability and carrying capacity analysis through field observations and measurements of beach biophysical parameters. Results indicate that Kuri Beach has a suitability level of 71.25% for beach recreation activities (S2 category), 76.47% for relaxation activities (S2 category), and 79.48% for swimming activities (S2 category). The area's carrying capacity can accommodate 400 people per day for relaxation, 106 people for beach recreation, and 40 people for swimming. Tourist perceptions reveal that 90% consider the beach beautiful and 79.20% feel comfortable. The research recommends enhancing tourism promotion, developing tourist facilities, and limiting visitors during weekends to ensure area sustainability. The success of tourism development depends on government policy support and active community participation in preserving the beach environment.

This study aims to determine the market share and type of marketing channels, as well as the proportion of marketing volume of mackerel (Rastrelliger sp) at the Kendari City Ocean Fisheries Port (PPS). This study was conducted in January-February 2024. The method used in this study was purposive sampling with descriptive analysis using a nominal and percentage approach. The types of data used were primary data and secondary data. Research data were obtained through observation, direct interviews, documentation and literature studies. The results of the study showed that the market share consists of two, namely the local market and the domestic market. The type of local market marketing channel consists of three types and the domestic market consists of one type. The highest proportion of marketing volume is in the local market in marketing channel II with a value of 73% and the lowest in marketing channel III with a value of 5%. The proportion of domestic market marketing volume has the same value in 2016-2019 at 100% while in 2020 it was 0% due to Covid-19. The highest proportion of market share is in the local market at 73% and the lowest in the domestic market at 27%.

PERTUMBUHAN DAN PRODUKSI Caulerpa lentillifera YANG DIBERI MIKROORGANISME LOKAL (MOL) ECENG GONDOK

Caulerpa lentillifera seaweed is a seaweed that has high economic value and is widely loved by people in the country and abroad. However, the production of Caulerpa lentillifera itself has not been sufficient because it is seasonal. Therefore, it is necessary to make efforts to increase the production of Caulerpa sp. by applying fertilizer in its cultivation. This study aims to determine the dosage (MOL) of water hyacinth that can provide the best growth and production as well as to determine the nutritional quality of Caulerpa sp. This study used a Complete Randomized Design (RAL) with 4 treatments and 3 replicates, with each MOL administered; Treatment A (control), Treatment B (5 mL MOL/L water), Treatment C (6 mL MOL/L water), and Treatment D (7 mL MOL/L water). The data was analyzed by the ANOVA Test and continued by the Duncan Test. that the administration of MOL water hyacinth with a dose of 6 mL MOL/L of water was the best dose for the growth, production, and nutritional quality of Caulerpa lentillifera. Water hyacinth in Caulerpa lentillifera can exert markedly different effects on absolute growth, specific growth rate, production, moisture content, protein, crude fat, crude fiber, BETN, and ash. The best treatment is C treatment (6 ml MOL/L water).
