Abstract

The Talakayya Farmers’ Group in Mandalle Village, West Bajeng Subdistrict, Gowa Regency, South Sulawesi, uses combine harvesters during the rice harvest to improve cost efficiency and reduce labor requirements. This study aims to analyze the dynamics of farmers’ adoption of combine harvesters in terms of knowledge, attitudes, skills, and the economic and social impacts resulting from their use. This study employs a qualitative case study approach. There were eight informants, all of whom were members of the Talakayya farmers’ group. Data were analyzed descriptively through observation, interviews, and documentation. Specifically, social impacts were analyzed through coding and visualized using NVivo version 12. The results indicate that farmers understand the machine’s functions and benefits and hold a positive attitude toward it, as the machine saves harvesting time and reduces labor costs from an economic perspective. However, in terms of skills, they are not yet able to operate the machine independently. The social impact has led to a decline in mutual assistance and social interaction. The conclusion of this study is that farmers’ adoption of the combine harvester is limited to their knowledge and attitudes toward its use in agricultural mechanization and has not yet reached the level of technical skills required to operate it. The government is seen as needing to facilitate technical assistance and training.

Abstract

Cayenne pepper is a high-value horticultural commodity, but farm income is sensitive to output-price and production-cost changes. This study analyzed cost structure, revenue, income, profitability heterogeneity, financial feasibility, and switching values for cayenne pepper farms in Bululoe Village, Jeneponto Regency. The survey involved 34 farmers selected by simple random sampling from a population of 137; sample size was determined using Slovin's formula with a 15% error tolerance. Individual one-season observations were analyzed using descriptive statistics, the R/C ratio, simple accounting break-even points, unit production cost, and switching values. The pooled R/C ratio was 3.07, while the mean individual R/C was 3.34 (SD 0.63; range 2.62-4.95); all 34 farms had R/C > 1. Mean individual farm income was IDR 24.39 million per season, ranging from IDR 8.49 to 53.77 million. Re-summing individual land records produced 13.14 ha and an aggregate productivity of 4.68 t/ha. Pooled production cost was approximately IDR 6,525/kg, while individual unit costs ranged from IDR 4,040 to 7,647/kg. Labor accounted for about 78% of recorded total cost. Holding other factors constant, the pooled selling price could fall by 67.38% or total cost could rise by 206.52% before R/C reached 1; individual price-decline thresholds ranged from 61.77% to 79.80%. Results should be interpreted as financial feasibility based on recorded costs because the same IDR 20,000/kg price was used for all respondents and family labor was not fully valued at opportunity cost.

Abstract

Seagrass ecosystems are part of the components of tropical coastal ecosystems that have high ecological and economic functions. They provide habitat for marine biota, act as sediment stabilizers, and are very effective blue carbon storage. This study aims to analyze the structure of seagrass communities in the waters of Sembilan Island, Sinjai Regency, South Sulawesi. Data collection was conducted at six stations using quadrat transect and line transect methods to identify species and calculate ecological indices. These indices include Shannon-Wiener Diversity, Pielou Evenness, and Simpson Dominance. The identification results showed that there were seven seagrass species, namely Enhalus acoroides, Thalassia hemprichii, Syringodium isoetifolium, Cymodocea rotundata, Halodule pinifolia, Halophila minor, and Halophila ovalis. The diversity index value was 1.579 (moderate category), uniformity 0.811 (high), and dominance 0.244 (low), describing a relatively stable and ecologically balanced community. Inter-station correlation analysis showed r values ranging from 0.89 to 1.00, indicating high spatial homogeneity and strong ecological connectivity between observation sites. The resulting community structure is a combination of long-lived climax species (E. acoroides, T. hemprichii) and short-lived pioneer species (H. pinifolia, and H. ovalis), which together maintain regeneration dynamics and ecosystem function. These findings indicate that the seagrass meadows on Sembilan Island are healthy, stable, and functioning optimally as a blue carbon ecosystem, playing a crucial role in storing carbon, stabilizing sediments, and supporting coastal resilience to the impacts of climate change.

Abstract

The habit of consuming less nutritious snacks among children remains a contributing factor to low protein and essential nutrient intake. The development of healthy snacks based on local fishery resources is one effort to improve children's nutritional quality. This study aims to evaluate the nutritional content and acceptance level of tilapia-based fish sticks (Oreochromis mossambicus) as a healthy snack alternative. The study used a Completely Randomized Design (CRD) with one factor, namely the addition of tilapia fish meat of 0%, 15%, 30%, and 45% with three replications. The parameters observed included water, protein, fat, ash, and carbohydrate content, as well as the level of panelist acceptance through a hedonic test. The results showed that the addition of tilapia fish meat had a significant effect (P<0.05) on increasing protein levels, with the highest value being 23.78% in the 45% treatment, and reducing carbohydrate levels to 49.43%, while water, fat, and ash levels did not differ significantly between treatments. The hedonic test results showed that all formulations were well-received by the panelists, with the formulation with 45% tilapia fish being the most acceptable for appearance, aroma, taste, and texture. This formulation has the potential to be developed as a healthy snack alternative with good nutritional quality and consumer acceptance to support children's nutritional status.

Abstract

This study aims to analyze the morphometry of Dillenia in West Sulawesi and its relationship with abiotic factors in the Buttupuang Protected Forest. This species has ecological, economic, and cultural value, but its population in nature is thought to be declining due to overexploitation and low natural regeneration, putting it at risk of local extinction. Understanding morphological variation and response to environmental factors is important as a basis for taxonomic identification, conservation, and sustainable use. The research methods included measuring the morphometry of leaves, fruits, and stems, as well as abiotic factors, using a sample size of 9 with three replicates, then analyzed using PCA with the PAST application. The dendrogram results showed that the Dillenia population was divided into two clusters, namely cluster I (area A, separated as a distinct group) and cluster II (areas B–C with a similarity index of 96.7%). Biplot analysis revealed that the main abiotic factors associated with morphometric diversity were temperature, air humidity, and soil pH, with growth parameters more closely related to humidity. Area A was influenced by temperature, area B by humidity and growth, while area C was more inclined towards edaphic factors (soil pH) and leaf size.

Abstract

Skipjack tuna (Katsuwonus pelamis) is a pelagic fish that has oceanic characteristics that always migrate from one water to another that has oceanographic, biological and meteorological conditions that suit its habitat. Currently the use of geographic information system (GIS) technology is widely used in obtaining information about oceanographic characteristics, one of which is the use of satellite imagery data. With the collaboration between GIS and the latest satellite, namely Sentinel-3, it can determine potential fishing zones. The purpose of this study is to examine the effect of sea surface temperature parameters on catches to determine the potential zone for skipjack tuna fishing in the Makassar Strait Waters. This study uses a quantitative method, namely using primary data, namely collecting coordinate points of fishing and catches of skipjack tuna in the Makassar Strait Waters and secondary data, namely oceanographic parameter data in the form of sea surface temperature data obtained from Sentinel-3 satellite imagery during January and February, data analysis through a histogram of the relationship between skipjack tuna catches and SST oceanographic parameters, making a map of potential areas for skipjack tuna fishing using ArcGIS 10.8 software. The results of the study showed the optimum sea surface temperature range for catching skipjack tuna is 29 - 30oC with a catch of 841 - 1010kg and is at the coordinate point 118.1o - 118.3o East Longitude and 2.2o - 2.5o South Latitude. The optimum chlorophyll-a range is 0.1 - 0.4 mg/m3 with a catch of 655 - 738kg located at the coordinate point 117o - 118o East Longitude and 2.4o - 2.5o South Latitude.
