Editorial: Seed Science and Technology. Volume 49 Issue 3 (2021)

This issue of Seed Science and Technology is a good reflection of the wide scope of the field of study. Species of interest include major cultivated crops as well as wild and native species. Likewise, research topics span a wide array of subjects relevant to those interested in basic seed biology, production, testing, ecology, conservation and biodiversity. Understanding basic mechanisms of seed dormancy and germination remains a major topic of interest. Seed quality and its attributes are also of particular interest, as evidenced by research articles on seed vigour, health, genetic purity and physical characterisation.

PENGEMBANGAN GAME ACTION-ADVENTURE BERDASARKAN CERITA RAKYAT SULTAN SURIANSYAH BERMUATAN KEARIFAN LOKAL BANJARMASIN BERBASIS PERANGKAT BERGERAK

Sultan Suriansyah was the King of Bandarmasih (the First King of Banjar) who ruled from 1520-1540 and was the first king to embrace Islam. Tourism-related to the tomb of Sultan Suriansyah is very popular among the people of Banjar. However, the folklore that tells about Sultan Suriansyah is not as popular as his tomb, many young people today don't know it, even across Indonesia it is also not well known for this folklore from South Kalimantan. The purpose of this research is to design and build a folklore game with an action-adventure genre that adapts the story of Sultan Suriansyah to preserve Banjarmasin folklore and as a means to understand grammar in the Banjar language. The research method used is the Game Development Life Cycle with stages in the form of Pre-Production, Production, Testing, and Post-Production. The results show that the game design has been produced in the form of a storyboard and then developed using Godot Engine software with the output of the (.apk) extension application that can be installed on mobile devices. Then the Playtesting and Gameflow testing was also carried out which involved 50 respondents as players with an age range of 13-15 years, the results showed that the games built and tested had met the elements and criteria with an overall average value of 4.84 and no bugs were found in the game. Tests related to player knowledge and justification for using games as a media to preserve folklore and a means to understand the Banjarese language have also been carried out with very good results.

Inspection of Transparent Objects with Varying Light Scattering Using a Frangi Filter

This paper proposes a new machine vision method to test the quality of a semi-transparent automotive illuminant component. Difference images of Frangi filtered surface images are used to enhance defect-like image structures. In order to distinguish allowed structures from defective structures, morphological features are extracted and used for a nearest-neighbor-based anomaly score. In this way, it could be demonstrated that a segmentation of occurring defects is possible on transparent illuminant parts. The method turned out to be fast and accurate and is therefore also suited for in-production testing.

PENGEMBANGAN GAME MULTIPLAYER PENGENALAN BUDAYA GEBUG ENDE SERAYA KARANGASEM BERBASIS ANDROID

Tujuan dari pengembangan game ini yaitu sebagai media pengetahuan game berbasis budaya yang dapat membantu masyarakat untuk lebih mengenal budaya khususnya Gebug Ende Seraya Karangasem. Memperkenalakan budaya untuk melestarikan budaya bali sangat perlu deperhatikan karena banyak tradisi dan budaya yang jarang diketahui oleh anak-anak maupun orang dewasa, permasalahan dasar yang dihadapi dalam upaya pelestarian trasdisi ini adalah kurangnya kesadaran masyarakat akan pentingnya mengetahui warisan leluhur khususnya yang ada di Bali. Pengembangan game ini mengunakan metode GDLC (Game Development Life Cycle) yang terdiri dari enam tahap, diantaranya adalah Initiation, Pre-Production, Production, Testing, Beta dan Release. Terdapat empat jenis pengujian yang dilakukan yaitu uji black box, uji ahli isi, uji ahli media dan uji tingkat pengalaman pengguna menggunakan pengujian UEQ (User Experience Questionnaire). Hasil yang telah diperoleh dari pengujian yang telah dilakukan mendapatkan respon yang sangat baik.Kata Kunci : Games, Gebug Ende, GDLC

UNCONVENTIONAL FEED ADDITIVES: WHEY-MINERAL-VITAMIN SUPPLEMENT IN THE DIET OF YOUNG PIGS ON FATTENING DURING THE TESTING PERIOD

The article presents the data of production testing on young pigs on fattening when fed as part of a feed mixture of the best dosage of a serum-mineral-vitamin supplement in the amount of 30 g per day per head. The daily increase during the study period was 531 g in the control group and 548 g in the experimental group, or 3.2% more. The exchange energy costs per 1 kg of gain were 10.4% lower in the experimental group compared to the control group animals. The level of profitability of pork production was 1.6% higher in the experimental group.

Сentrifuging element gating system

The design of centrifuging element gating and feeding system for castings made of heat-temperature nickel alloys is proposed, method for calculating its main sizes is developed. The experimental and production testing showed the high effi ciency of this gating system in retaining of slag particles and blockages, which made it possible to signifi cantly reduce the level of rejected castings.

State, problems and prospects for the development of sugar beet seed production in the Krasnodar Territory

A retrospective analysis of the state of sugar beet seed production in the Krasnodar Territory has been carried out. The problems are reflected and the factors of intensification of the seed-growing process are named as a necessary condition for the restoration of domestic seedgrowing and an increase in the proportion of seeds of the Kuban selection in the crops of sugar beet in the North-Caucasian region. The results of production testing of sugar beet hybrids selected by the FSBSI “Pervomaysky Selection und Experimental Station of Sugar Beets” in 2019-2020 are presented.
