Abstract

The palm oil industry is the largest economic supporter for the Indonesian economy from the agricultural sector. Behind the success story of this activity, there are environmental consequences regarding the decline in land quality as a result of improper land management. To study the effect of oil palm plantation management on soil fertility, a study was conducted in three locations, Dharmasraya Regency (Kanhapludult), South Solok (Dystrudepts) and South Coast (Haplohemists) in West Sumatra. Research data were collected from 2017 to 2022 respectively, and analyzed. The results showed that soils from Dharmasraya (DM) and South Solok (SS) experienced a decrease in pH value during the study period, while opposite results were found at the PS location. Total Carbon (C) and Nitrogen (N) content at the DM and SS locations were found to be similar, while at the PS location these parameters were much higher because the soil came from organic matter. Comparable results were also found for KTK, where the DM and SS research locations were lower compared to the PS location. The content of macro nutrients (nitrogen, phosphorus and potassium) in the soil describes the PS location much better compared to DM and SS. Because the PS location is organic soil, the higher nutrient content can be harmful to the environment because it can easily leak into water bodies which can trigger eutrophication

Abstract

The development of ecotourism in Kapalo Banda, Limau Manis, Padang, has potential to be expanded into agro-ecotourism through multi-stakeholder involvement. Key attractions include the scenic of river flows, agricultural cultivation, and stingless bee keeping, which support environmental sustainability and the local economy. With high vegetation diversity, the potential for stingless bee (galo-galo) breeding as a creative economic initiative offers new opportunities. This program aligns with the West Sumatra Provincial Government’s efforts to establish the area as a honey production center. However, challenges such as low colony production due to limited knowledge of farming techniques and the availability of flowering feed hinder its development. Through community engagement, empowerment activities were conducted from June to September 2024, including socialization, demonstrations, and training in bee farming techniques, supported by expert teams. Education focused on the potential of galo-galo and marketing strategies for local products. The results of this program indicate improved community skills and knowledge, supporting local economic sustainability and biodiversity conservation. Kapalo Banda partners have the potential to serve as a model for community empowerment based on natural resources, effectively enhancing community welfare. Multi-stakeholder involvement in developing Kapalo Banda Ecotourism has resulted in a series of activities ranging from cultivation preparation, colony propagation techniques, harvest preparation, to downstream processing and product marketing.

Abstract

This study investigates the relationship between sea surface temperature (SST) and chlorophyll-a concentration in relation to the catch results of mackerel fish (Rastrelliger kanagurta) in Pulau Tikus Beach, Bengkulu City. Remote sensing data from the Aqua MODIS satellite sensor were analyzed over a 12-month period (May-April 2025) to assess monthly fluctuations in SST and chlorophyll-a as indicators of marine productivity. SST values ranged from 28.9°C to 31.2°C, matching the optimal thermal range for mackerel spawning. Chlorophyll-a concentrations ranged from 0.5 to 3.4 mg/m³, indicating a high abundance of phytoplankton and biologically fertile waters. Fishing coordinate data showed that the highest mackerel catches occurred around Pulau Tikus, with Robin-type boats operating approximately 7-8 nautical miles offshore. The relationship between SST and chlorophyll-a revealed that increasing SST was associated with elevated chlorophyll-a levels at depths of 8-15 meters, thereby increasing the probability of mackerel presence.

Abstract

Frigate tuna (Auxis thazard) is a pelagic and neritic fish resource that has economic value. Fish diet is one of the important information in monitoring the sustainability of fisheries resources in the future. This study aims to determine the composition of food and determine the Index of Preponderance of frigate tuna caught by fishermen in West Sumatra waters. The method used in this study was random sampling by taking 98 samples of frigate tuna obtained from the catch of fishermen in West Sumatra waters landed at the Air Bangis Fish Landing Center, West Pasaman Regency, and Gaung Fish Auction Site, Padang. The analysis used the Index of Preponderance to determine the main food, additional food, and complementary food. The results showed the composition of food in the stomach of frigate tuna consisted of 3 groups of organisms, namely zooplankton (61.04%), phytoplankton (31.82%), and pisces (7.13%). The main food of frigate tuna is zooplankton (62.10%), while the additional food are phytoplankton (27.73%), and pisces (10.16%). The availability of frigate tuna food in West Sumatra waters supports the sustainability of the frigate tuna population in these waters.

Abstract

The frigate tuna (Auxis thazard) is important to the fishing industry in West Sumatra. The increasing demand for frigate tuna causes this fish to continue to be exploited. Exploitation carried out continuously can reduce frigate tuna production, so research needs to be done. The research was conducted to: (1) Know the growth pattern and factor condition of frigate tuna (A. thazard) in West Sumatra waters; (2) Know the reproductive biology of frigate tuna (A. thazard). Samples were collected from fishermen's catch in the waters of West Sumatra. Random sampling was conducted, and samples were measured for length and weight, followed by dissection to ascertain sex ratio, gonadal maturity level, gonadal maturity index, and fecundity. The results indicated that the fish's length ranged from 350 to 475 mm, with an average of 401.48 mm, and their weight ranged from 408 to 1,339 grams, with an average of 755.8 grams. The growth pattern is identified as positive allometric (b>3), indicating that weight gain surpasses length increases. The condition factor is in stable condition with an average of 1.24. The sex ratio is in an unbalanced condition with a ratio of males and females of 0.9: 1. The level of gonad maturity obtained is GML III and GML IV. The gonad maturity index of male fish ranged from 1.71 to 3.04 and female fish from 1.28 to 2.50. Estimated fecundity ranged from 261,468 to 2,775,590 grains. Based on several factors included in this study, the reproductive biology of frigate tuna in the waters of West Sumatra is favorable.

Abstract

Otters (subfamily Lutrinae) consist of 13 species distributed worldwide; however, their populations have been steadily declining due to land-use changes and hunting, while information on their presence in the rice fields of 2x11 Kayu Tanam District remains undocumented. This study was conducted with the objective of identifying and document tracks and signs of otter presence in the rice fields of 2x11 Kayu Tanam District. The research was conducted from November 2023 to February 2024 using a field survey method by observing tracks, spraints, and prey remains to determine the distribution of otter signs. Based on the distribution of tracks and signs found, it is suspected that only one species occurs in the area, namely Aonyx cinereus (small-clawed otter). The presence of Aonyx cinereus in the rice fields of 2x11 Kayu Tanam District was confirmed through tracks and other signs of activity. These findings provide a foundation for further research on otter ecology in rice field ecosystems and highlight the importance of conservation efforts to sustain their habitats.
