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.

Rice is a major food crop in Indonesia, but its productivity fluctuates partly due to pest and disease attacks. Tungro disease, transmitted by the green leafhopper (Nephotettix virescens), can significantly reduce rice yield. This study aimed to determine disease incidence, disease severity index, and plant height reduction caused by tungro disease in different rice varieties and lines. The study was conducted in the greenhouse of the BRMP Aneka Tanaman Umbi, Lanrang, Sidenreng Rappang Regency, using a Completely Randomized Design with five rice genotypes: Tukad Unda, TN1, Mekongga, Ciherang, and MR219. Each genotype had three replications, resulting in 30 test plants. The results showed that Ciherang and TN1 had the highest disease incidence, reaching 100%, and were classified as highly susceptible to tungro disease. Mekongga had an incidence of 83.33% and was classified as susceptible, while MR219 showed an incidence of 50% and was classified as moderately resistant. Tukad Unda showed no disease symptoms, with 0% incidence, and was classified as highly resistant. The highest disease severity index was recorded in Ciherang (9.00), followed by TN1 (7.00), Mekongga (6.33), MR219 (4.67), and Tukad Unda (1.00). The greatest plant height reduction occurred in Ciherang (16.00 cm) and TN1 (9.00 cm), while Mekongga, MR219, and Tukad Unda showed reductions of 2.33, 0.33, and 0 cm, respectively. Overall, Tukad Unda showed the highest resistance to tungro disease among the tested genotypes.

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.

Respon Pertumbuhan dan Hasil Bawang Merah Terhadap Aplikasi Pupuk Organik Cair Dan Benzyl Amino Purine (BAP)

Enhancing shallot productivity should focus on efficient, environmentally sustainable cultivation practices. Innovations in cultivation, such as the use of liquid organic fertilizers and plant growth regulators like Benzyl Amino Purine (BAP), represent a promising approach to sustainably improving yield. This study aimed to evaluate the effects of liquid organic fertilizer and BAP on the growth and yield of shallot plants, and to examine the interaction between different liquid organic fertilizer doses and BAP concentrations. The experiment was arranged using a Randomized Complete Block Design (RCBD) with two treatment factors. The first factor consisted of four levels of liquid organic fertilizer: 0 mL L?¹, 50 mL L?¹, 100 mL L?¹, and 150 mL L?¹, applied to the growing media. The second factor was BAP concentration, with three levels (0 ppm, 100 ppm, and 200 ppm), applied via foliar spraying. The combination of these factors resulted in 12 treatment combinations, each replicated three times, yielding a total of 36 experimental units. Each unit consisted of two plants, resulting in a total of 72 plants. The results indicated that the application of 500 mL L-1 liquid organic fertilizer combined with 200 ppm BAP significantly affected plant height at 5 weeks after planting (WAP) and had a significant single-factor effect on root number. A significant interaction effect was observed on plant height at 5 WAP. However, no significant effects were found on the number of tillers, stomatal number, stomatal density, bulb diameter, and overall shallot productivity.

Farmers’ capability determines the effectiveness of resource management and the sustainability of smallholder beef cattle enterprises. This study aimed to assess farmers’ capability in managing beef cattle among livestock groups in Timoreng Panua Village, Panca Rijang District, Sidenreng Rappang Regency. A survey was conducted from July to August 2024 involving 17 farmers selected from 116 members of eight livestock groups. Primary data were collected through structured interviews using a questionnaire and field observations, while secondary data were obtained from village records and relevant agencies. Five aspects were assessed: farming experience, husbandry performance, farming success, capacity to cope with production constraints, and access to capital. Each aspect was measured on a five-point Likert scale and analyzed descriptively using frequencies, scores, and achievement indices. All aspects were classified as moderate. Farming experience obtained the highest score of 57, equivalent to 67.1% of the maximum score, followed by husbandry performance at 53 (62.4%), farming success and capacity to cope with constraints at 52 each (61.2%), and access to capital at 50 (58.8%). The overall capability index was 62.1%. These findings indicate that relatively long farming experience has not been fully accompanied by stronger capital access and business management. Capacity-building programs should prioritize financing access, farm record keeping, feed management, animal health, and continuous group-based extension.

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.
