Abstract

This research was conducted in Sei Beras Sekata Village, Sunggal District, Deli Serdang Regency, North Sumatra Province. With an altitude of ± 25 meters above sea level. This study aimed to determine the response of rice growth (Oryza sativa L) to the provision of cow manure and liquid fertilizer. The design used was a Randomized Block Design (RAK) Factorial with the main treatment being solid organic fertilizer (A) with three treatments, namely L1 = (660 gr / Plot) 3 tons / Ha, L2 = (1100 gr / Plot) 5 tons / Ha, L3 = (1650gr / Plot) 7.5 tons / Ha. Organic fertilizer 3 treatments, namely, K1 = 2.5cc / liter, K2 = 5cc / liter, K3 = 7cc / liter. The parameters observed in this study were plant height per clump (cm), number of tillers per clump (stem), and number of productive tillers per clump (stem). The study showed that solid organic fertilizer treatment had no significant effect on all parameters. In contrast, liquid organic fertilizer significantly affected the number of productive shoots but did not significantly affect plant height per clump (cm) and number of shoots per clump (stems).

Abstract

This study aims to determine the effect of green fertilizer apu-apu and plant growth regulators on the growth and production of lettuce (Lactuca sativa L.). This study used a randomized block design (RAK) with two factors. The first factor is green fertilizer Apu-Apu with the symbol (K) consisting of 3 levels: K1 = 1 kg/plot, K2 = 1.5 kg/plot and K3 = 2 kg/plot. The second factor is plant growth regulators with the symbol (P) consisting of 4 levels: P0 = control (no treatment), P1 = 2 cc / l water, P2 = 4 cc / l water and P3 = 6 cc / l water. The results showed that green fertilizer apu-apu up to a dose of 2 kg/plot significantly increased the Height of fresh weight per plant, wet weight per plot and root weight per plot but did not affect plant height. The provision of plant growth regulators significantly increased plant height, wet weight per plant, wet weight per plot and root weight per plot. The administration of growth regulators up to a concentration of 6 cc/l of water resulted in the highest wet weight per plant and wet weight per plot. The interaction between apu-apu green manure and growth regulators did not significantly affect plant height, number of leaves, wet weight per plant, wet weight per plot and root weight per plot.

Abstract

This study analyzes the marketing strategy of banana chip products at the Keripik Ayu Ketaren MSME in North Sumatra. Although Indonesia is the largest banana producer in the world, the utilization of banana harvests is still relatively low. Banana chips, on the other hand, have significant market potential, especially as a healthy snack option. This study uses a SWOT analysis to identify MSMEs' strengths, weaknesses, opportunities, and threats. The results of the analysis show several strengths, such as good product durability and affordable prices, which can be utilized to expand the market. However, challenges such as limited capital and distribution networks must be addressed to support growth. Existing opportunities, including the increasing demand for healthy snacks and the potential of digital platforms, can help expand market reach. On the other hand, threats from larger competitors and lack of product innovation are risks that must be faced to overcome these challenges; the recommended strategies include improving packaging quality, flavor innovation to attract new consumers, and utilizing digital and e-commerce platforms to reach a wider audience. This study aims to provide valuable insights for MSME actors in developing effective marketing strategies, increasing the competitiveness of banana chip products, and supporting business sustainability in an increasingly competitive market.
