Abstract

Phosphorus (P) and potassium (K) solubilizing microbes have an important role in accelerating the solubility process of P and K sources which are difficult to dissolve. The purpose of this research was to study the effect of gamma irradiation on the growth rate of P and K solubilizer multifunctional microbes. The microbes used in this study were P and K solubilizer multifunctional bacteria (Staphylococcus pasteuri) and the P and K solubilizer multifunctional fungi (Aspergillus costaricaensis). The microbes were irradiated with gamma rays at a dose of 0; 1; 2.5 kGy. Tests for the rate of bacterial growth were observed through the results of optical density and Total Plate Count (TPC), while fungi were observed through measurement of colony diameter and TPC. Gamma irradiation effects increasing the growth rate of P and K solubilizer multifunctional bacteria (1.0 BPK 5 and 2.5 BPK 5) based on optical density values. At the time of calculating the population using TPC method, the increase in bacterial growth rate tended to be shown by isolates 2.5 BPK 5. The effect of gamma irradiation on the growth rate of fungi was indicated by the colony diameter of the isolate 1.0 BPK 5 which was wider than the wild type isolate or isolate 2.5 BPK 5. TPC results on fungi also showed that gamma irradiation affected the growth rate of fungi at 24, 96, 120, and 288 hours incubation time. Keyword: Gamma irradiation; microbe; growth and fertilizer

Abstract

This study analyzes the marketing strategies for cayenne pepper in Badung Regency, Bali, to support government policies aimed at enhancing horticultural competitiveness and farmer welfare. Conducted in the production centers of Mengwi, Abiansemal, and Petang, the research utilized a mixed-methods approach incorporating Internal Factor Evaluation (IFE), External Factor Evaluation (EFE), and Internal-External (IE) matrices, followed by a SWOT analysis. The results position the cayenne pepper agroindustry in Quadrant I (Strength–Opportunity), signifying robust internal capabilities and significant market potential. With an IFE score of 2.820 and an EFE score of 2.870, the study identifies high product quality and rising market demand as primary drivers, while production fluctuations and price uncertainty remain key challenges. To optimize this potential, the study recommends a multi-faceted strategy: stabilizing production through strengthened farmer groups, launching chili subscription programs for culinary businesses, and utilizing digital platforms. Furthermore, establishing weekly farmers' markets, fostering partnerships with supermarkets, and diversifying processed products are essential to stabilizing supply and improving the economic welfare of local farmers.
