Abstract

Based on the development of ornamental plant production of orchid plants. It continues to show vast numbers every year. This shows that orchid plants have the potential to be developed. The farmers' understanding of the prospect of farming and the economic value of Vanda orchid plants is minimal. It's often orchid business cannot be maximized. The purpose of this study is to analyze the financial feasibility of the vanda orchid ornamental plant business in Dd Orchid Nursery, Junrejo District, Batu City, using the R/C ratio, Break Event Point (BEP), Payback Period (PP), Net Present Value (NPV), and Internal Rate of Return (IRR). The population and sample of this study were all farmers in Dd Orchid Nursery, totalling 30 people. The research data was collected using questionnaires, interviews, and documentation techniques. Data analysis conducted includes R/C ratio, Break Event Point (BEP), Payback Period (PP), Net Present Value (NPV), and Internal Rate of Return (IRR). The data was analyzed using the Microsoft Excel program. The results showed an R/C ratio of 4.57. BEP business production is 645 bunches. BEP Price is Rp. 2.269. The payback period (PP) generated amounted to 1.19. Net present value (NPV) amounted to Rp. 27,909,153. And the IRR percentage value obtained is 84%. It can be concluded that the Vanda Orchid Business at DD' Orchid Nursery is a business that has excellent financial viability. Orchid farmers at DD' Orchid Nursery can continue to expand their target market and expand to other types of orchids with profitable profit values.

Abstract

This study profiles the phenotypic characteristics and production performance of Peranakan Ongole (PO) bulls in Bojonegoro Regency, an officially designated PO cattle breed-source site, and evaluates their capacity to support sustainable community-based breeding. A descriptive-quantitative survey was conducted over two months in three subdistricts (Tambakrejo, Sekar, and Kedungadem), selecting 180 purposively sampled bulls aged ≤50 months. Primary data comprised qualitative (coat color, horn shape, ear hair pigmentation, and other SNI–specified traits) and quantitative (heart girth, body length, height at rump) phenotypic measurements; secondary data on birth, weaning, and one-year body weights were obtained via farmer questionnaires, key-informant interviews, and official records. Descriptive statistics revealed that all sampled bulls met SNI qualitative standards, with the sole exception of progressive ear-hair graying in mature animals. Quantitative traits consistently exceeded Class I SNI minimum (such as mean chest girth 163–191 cm; body length 130–158 cm; withers height 130–141 cm). Mean production weights were 20.0 ± 3.3 kg at birth, 116.5 ± 9.0 kg at weaning, and 138.3 ± 13.6 kg at one year, surpassing or matching earlier reports. Observed genotype, environment synergy, driven by abundant local forage and traditional management, underscores the bulls’ preserved genetic merit and breeding potential. These findings furnish a strategic basis for selective male choice and policy interventions to enhance PO genetic improvement and breeder livelihoods in Bojonegoro.

Abstract

This study aims to analyze and empirically prove the effect of product quality, price, service quality, and convenience on customer satisfaction at Waroeng Steak and Shake in Malang City. The main focus is to identify the most contributing determinants in shaping positive customer experiences amidst intense competition in the culinary industry. A quantitative approach with a survey method was employed , using purposive sampling of 100 active customers. This sample size meets the statistical power criteria for regression analysis in the context of consumer behavior research. Data were analyzed using multiple linear regression. The results indicate that partially and simultaneously, product quality, price, service quality, and convenience have positive and significant effects on customer satisfaction. The findings reveal that service quality is the most dominant factor in increasing customer satisfaction, followed by convenience, price, and product quality. The coefficient of determination (R2) of 70.3% shows that this model has high predictive ability in explaining variations in customer satisfaction.
