Abstract

Instant organoleptic test of ginger against three varieties of ginger (Zingiber officinale) is descriptive research. The purpose of this study is to examine the feasibility of processed ginger formulations and their effect on the level of preference of panelists as consumers for instant ginger as an herbal drink made from raw materials with three varieties of ginger. This research was conducted in May-July 2023 at the Production Laboratory of the Faculty of Agriculture-UWKS using a one-factor Complete Randomized Design (RAL) consisting of 3 levels. The treatment is the use of the main raw materials of ginger with 3 varieties, namely J1 = elephant ginger (2023 research results); J2 = red ginger; J3 = empirrit ginger. The observation parameters were carried out through Organoleptic tests on product properties, namely taste, aroma, texture, color, physical appearance, and knowing the level of preference of panelists for ginger instant drinks from 3 varieties of ginger, and each treatment was repeated three times with 10 panelists each repeat. This hedonic test with sensory analysis of instant ginger products is used to guess what products the panelists like the most with the level of liking. The method used in this Hedonic Test, consists of 5 levels: (1) very dislike, (2) dislike, (3) ordinary, (4) like, and (5) very like From the results of this study is expected to provide benefits to the public in consuming ginger as a healthy herbal drink, as well as for other researchers who are interested in similar research. Three levels in the treatment of the use of three varieties of ginger on instant results of ginger, from organoleptic tests give results that elephant ginger has advantages in aroma and color, empirrit ginger has the advantage of soft texture and red ginger has a good taste.

Abstract

The research consists of two stages, the first being the development of LOF production from water hyacinth and banana peel applied to ginger plants. The purpose of the study is to determine the extent to which the application of liquid organic fertilizer (LOF) can enhance the early growth of ginger plants. The second is the cultivation of ginger plants by applying various types of LOF compared to ginger plants without LOF application. The research was conducted from the end of August to November 2025 in Banjar Poh Village, Sidoarjo District, Sidoarjo Regency.  Research hypothesis: (1) It is suspected that different LOF applications will result in different early growth in ginger plants, (2) it is suspected that the use of banana peel LOF provides better early growth in ginger plants compared to other treatments. The study used a Randomized Block Design (RBD) method with one factor consisting of 4 treatments. The treatment involved the provision of types of LOF, namely P1 = without LOF; P2 = LOF water hyacinth; and P3 = LOF banana peel P4 = EM4 (Effective Microorganisms 4). Each treatment was repeated 3 times, and each repetition had 3 plant samples. Observations of the early growth of ginger plants include shoot height, number of shoots, and number of leaves. The obtained data were analyzed using analysis of variance, and if there were significant differences, it was followed by the Least Significant Difference (LSD) test at 5%.
