Abstract

ABSTRACTwaxy corn or glutinous corn is a special type of corn that has a delicious taste, is more savory, fluffier andsofter. Seed quality consists of three components, namely: physical quality, physiological quality, geneticquality. This study aims to determine and study the quality of waxy corn seeds in Bolaang MongondowRegency. The research was conducted in Manado. This research took place from September to October 2020.This experiment used a completely randomized design (CRD), with 3 (three) treatments, namely the source ofwaxy corn seeds from several villages in Bolaang Mongondow Regency consisting of treatment P1 = seedsfrom the village Treatment Threshold P2 = Seed from Pusian Village Treatment P3 = Seed from Insil Village.Each treatment was repeated 4 (four) times in order to obtain 12 experimental units. Result of the experimentshowed The waxy corn in Ambang Village has a different quality from the quality of the seeds from PusianVillage and Insil Village. The quality of seed in Desa Ambang was characterized by germination rate of 88%,vigor index of 79%, synchronous growth of 86% and germinating speed of 28.44% / etmal. The seed qualityof Pusian Village is characterized by germination rate of 99%, vigor index of 83%, synchronous growth of98% and germinating speed of 31.53% / etmal and Village of Insil which has 100% germination, vigor indexof 83%, synchronous growth of 99% and speed of germination of 31.86 % / etmal.Keywords: Seed Quality, Pulut Corn

Abstract

Jagung pulut (Zea mays var. ceratina L.) merupakan salah satu jenis varietas tanaman jagung, yang memiliki keunikan tersendiri dibandingkan varietas tanaman jagung lainnya yaitu memiliki pati dalam bentuk amilopektin sebesar 95,75%. Penerapan teknologi dapat digunakan untuk membantu meningkatkan mutu benih yang mengalami penyimpanan. Salah satu upaya yang dapat dilakukan untuk meningkatkan viabilitas dan vigor benih yaitu dengan menggunakan Zat Pengatur Tumbuh (ZPT). Ekstrak bawang merah memiliki kandungan ZPT diantaranya adalah hormon auksin dan giberelin. Penelitian ini bertujuan untuk mengkaji adanya pengaruh pemberian ekstrak bawang merah dalam bentuk perendaman benih selama 6 (enam) jam terhadap viabilitas dan vigor jagung pulut. Penelitian ini menggunakan metode Rancangan Acak Lengkap (RAL) dengan 5 (lima) taraf perlakuan dengan 5 (lima) kali ulangan. Setiap satuan percobaan menggunakan 25 butir benih sehingga diperoleh 625 butir benih. Hasil penelitian menunjukkan bahwa respon viabilitas dan vigor benih jagung pulut yang telah mengalami penyimpanan selama 1,5 tahun berpengaruh nyata terhadap pemberian ekstrak bawang merah. Pemberian 20% ekstrak bawang mampu memberikan respon terbaik dalam meningkatkan daya berkecambah (96,8%), kecepatan tumbuh (27,4%), keserempakan tumbuh (96,8%) dan indeks vigor (95,2%) pada benih jagung pulut yang mengalami penyimpanan.

Abstract

This Zingiberaceae plant is widely used as medicine, including temulawak. Because curcuma (C.xanthorrhiza) is a medicinal plant that has many benefits and includes plants needed in large quantities compared to other medicinal plants. Traditionally rhizomes Temulawak is used to treat stomach ailments, liver disorders, constipation, diarrhea, dysentery, fever, hemorrhoids, hypotriglyceridaemic, and anti-inflammatory. Study about plant Curcuma local ignite still not enough researched so that not yet get information compounds which contained in the local curcuma of North Sulawesi for the development for biopharmaceutical development, mapping in the distribution of plants, ecology, plant conservation and protection to maintain local wisdom. Histochemical Test is a method to determine the content of chemical compounds in a plant tissue qualitative. Testing can be done by adding a special reagent or solution to the incision organ plant and will give color which Specific. Activity study this will test curcumin compound group on local ginger from North Sulawesi by histochemical method. research that done is study non experiment with design descriptive qualitative. The results showed that North Sulawesi local white temulawak powder contained curcumin in a sample with a sample weight of 0.10 g at a sample spotting volume of 20 µl with a sample spotting volume of 2040 nanograms, curcumin levels were <0.10 nanograms/mg. Curcumin biosynthesis is influenced by site conditions, agro-climate, genotype, and plant cultivation.

Abstract

This study aims to evaluate the antioxidant activity, total phenol, yield and evaluation of the panelists' preference level including color, taste and aroma of instant sarabba. Sarabba is processed into an instant drink to extend the shelf life of the sarabba drink and is practical.  The research method used was a completely randomized design (CRD) method with 4 treatment levels of the proportions of red ginger extract and cinnamon extract namely A (100% : 0%), B (95% : 5%), C (90% : 10%) ) and D (85% :15%) with 3 repetitions. The analytical method used in this research is the Folin Chiocalteau method for the total phenol test, the DPPH (1,1-diphenyl, -2 picrylhydrazyl) method for the antioxidant activity test. The results showed that the IC50 of instant sarabba ranged from 662.13 - 886.93 ppm and total phenol ranged from 2.21 - 6.75 mgGAE/100 g sample. Treatment of the proportion of 100% red ginger extract and 0% cinnamon extract had the strongest antioxidant activity with IC50 of 662.13 ppm and total phenol with a value of 6.75 mgGAE/100 g simple
