Abstract

Sorghum is one of the cereal crops that has good growth adaptation and production on dry land so that it has the potential to be developed in Indonesia. Besides being able to produce in dry areas, sorghum has a higher protein content compared to corn and cracked rice, but lower than wheat. Local sorghum used in this study included local Jember, local Demak, local Nganjuk, and local Majalengka. The level of genetic diversity of sorghum in Indonesia is still relatively low. Therefore, it is necessary to test the genetic diversity of sorghum with plant breeding. To obtain genetic diversity, this research conducted identification using RAPD molecular markers with 9 primers, namely OPA- 01, OPA-02, OPA-03, OPA-04, OPA-05, OPA- 06, OPA-11, OPA 17, and OPA 18. Based on the results of RAPD, the results of DNA bands were obtained which were continued with the NTSYSpc program to produce a kinship tree between local sorghum plants. From the results of the phylogenetic tree, it is known that the local sorghum of Majalengka and Lamongan have a parallel kinship, which means that the sorghum is genetically the same. Meanwhile, the genetic diversity of local sorghum in Jember and Demak is far compared to Lamongan and Majalengka. Nganjuk local sorghum has a genetic diversity line position in the middle (Jember, Demak) and (Majalengka, Nganjuk).

Abstract

Plants have natural compounds that can stimulate plant growth and development called phytohormones. Phytohormones can be produced endogenously by plants themselves and are not optimal. Therefore it requires exogenous phytohormones that come from outside the plant. In some cases, non-pathogenic bacteria can promote plant growth and be used in agriculture as biofertilizers. Soil rhizospheres from crops are suspected that the soil in the root area (rhizosphere) contains bacteria that stimulate plant growth. Hormones that play a role in plant growth function in division, enlargement of sprout cells, and division of cells at the root growth point. This research aims to determine bacteria that potentially produce the hormone auxin. This research identifies bacterial isolates from microscopic and macroscopic characterization. Screening isolates of auxin-producing bacteria using colorimetric methods and spectrophotometric methods. The results of characterization and screening from 5 samples showed that the bacterial samples that had the potential to produce auxin were samples isolated from eggplant soil (e) with a concentration of 6.5 ppm. The auxin produced is auxin IBA (Indole-3-butyric acid). The IBA auxin content is high enough to be applied as a plant growth-promoting bacteria.

Abstract

indonesia is a country known for its abundant biodiversity. however, the majority of its people still make rice as a daily staple food, making the price of rice continue to increase until it is difficult to reach by low-income people. therefore, it is necessary to develop alternative local food to replace rice to avoid a food crisis. One of the alternative plants is sorghum. Because sorghum has many benefits besides as food as well as bioenergy. That way it is necessary to make efforts to develop sorghum, one of which is by means of embryogenic callus tissue culture techniques by adding a concentration of 2,4-D. This research was conducted in the Laboratory of Nutraseutical and Pharmaseutical Division of Center for Development of Advancd Science and Technologies (CDAST) UPA Waste Management and Integrated Laboratory, University of Muhammadiyah Jember by using Completely Randomized Design (CRD) with a single factor namely A0 (control), A1 1 ppm, A2 2ppm, A3 3ppm, A4 4 ppm which was repeated 3 times. The variables under observation are the callus's color, texture, percentage, and time of formation. According to the study's findings, the application of 4 ppm 2,4-D produced the best results when compared to other 2,4-D treatments. These treatments were able to produce callus at a rate of 4.11 his, 100% of the total number of callus, crumbly texture, and pale yellowish color.

Abstract

Bondowoso is the best tape-producing region in East Java, with a production of 435,969 kg in 2018 . One of the tape production centers in Bondowoso is UD. Raja Tape. This study aims to identify the quality attributes of Raja Tape products and determine the operational policies needed to improve product quality at UD. Raja Tape. The Quality Function Deployment (QFD) method is used to identify and understand customer needs and desires into relevant technical specifications for the production process. This research was conducted over three months, using primary data obtained through field observations and interviews, as well as secondary data from related literature. The research stages include identifying products and competitors, conducting product surveys to gather the voice of the customer, identifying technical parameters, analyzing the relationship between customer importance and technical parameters, and constructing the House of Quality (HoQ). The results indicate that the application of QFD can identify key areas that need improvement in the tape production process, such as raw materials, fermentation techniques, and packaging. Implementing the recommendations from the QFD results led to significant improvements in tape product quality, marked by increased customer satisfaction and reduced complaints. This study demonstrates that the QFD method can be an effective strategy for improving product quality in the traditional food industry.

Abstract

Crackers available in the market only provide a small portion of daily protein needs. Tuna (Euthynnus affinis) belongs to the Scombridae class and is an important commodity in Indonesia. The high nutritional value of tuna fish includes a considerable amount of protein, ranging from 22.6-26.2 g/100 grams of meat. Of the various ingredients that can be added to increase the protein content of crackers, one option is to use tuna flour due to its high protein content. This study aims to identify the optimal ratio and drying period for certain chemical properties as well as considering color, aroma and taste preferences by panelists as well as the shelf life of popular tuna crackers. The parameters used in this study include moisture content, ash content, fat content, protein content which measures the nutritional value; pH which indicates the level of acidity; swelling strength as an indication of textural quality along with organoleptic tests (taste, color, aroma and overall preference) which enables sensory evaluation analysis. The results showed that crackers with the addition of tuna flour have met the quality requirements of SNI 2973-2018. The tuna flour crackers formulation has a moisture content of 0.4%, ash content of 0.2%, protein content of 7.11%, fat content of 16%, pH of 6.48-6.50 and expandability of 0.6%.
