Anthocyanins are compounds that are responsible for giving color to the fruit skin, these compounds are regulated by the MYB transcription factor genes. Single Nucleotide Polymorphism (SNP) mutations in the exon region of the MYB gene can change amino acids that affect enzyme activity, resulting in phenotypic variations in fruit color among individuals in the same species. This study aims to find SNP in MYB genes from mango peel varieties Arum Manis, Gedong Gincu, Manalagi, Golek, and Cengkir. The research was conducted in three main stages, namely isolation of mango peel DNA, Polymerase Chain Reaction (PCR), and sequencing process by Macrogen Inc (Singapore). The results of multiple sequence alignment of the amino acid MYB transcription factor genes showed a base difference which resulted in the appearance of a stop codon from SNP 337 A→T and SNP 338 A→G which affected the phenotype of fruit skin color. The SNP that raises the stop codon can be recommended to differentiate the anthocyanin pigmentation phenotype on the red skin of the mango Gedong Gincu from the skin color of other mangoes. The presence of SNP causes premature stop codon that occurs in the MYB transcription factor gene and is thought to have an effect on anthocyanin pigmentation. ","PeriodicalId":420744,"journal":{"name":"Jurnal Hortikultura","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123438886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Penelitian dilaksanakan pada bulan November 2018 sampai Januari 2019 di Desa Alasmalang, Kemranjen, Banyumas. Percobaan yang dilakukan merupakan percobaan pot dengan rancangan faktorial. Perlakuan pada penelitian ini adalah kombinasi antara zat pengatur tumbuh (kontrol, ekstrak tauge, air kelapa, IBA, dan BAP) dan jumlah daun entres (2, 4, dan 6 helai). Rancangan penelitian yang digunakan yaitu Rancangan Acak Kelompok Lengkap dengan 15 perlakuan dan diulang tiga kali. Hasil penelitian menunjukkan perlakuan ZPT IBA dan BAP memberikan pengaruh nyata terhadap jumlah tunas sambung pucuk tanaman durian, yaitu sebesar 2,711 dan 2,822 dan perlakuan jumlah daun entres dua helai memberikan pengaruh yang nyata terhadap waktu pecah tunas, jumlah tunas, dan pertambahan jumlah daun sambung pucuk tanaman durian, yaitu sebesar 2,3 helai.KeywordsSambung pucuk durian; Daun entres; Zat pengatur tumbuhAbstractVegetative propagation of plants using shoot grafting can be used as an alternative to produce quality seeds. The problem that often occours in top grafting is the failure to graft. This experiment aims to obtain the type of plant growth regulator, the number of scion’s leaves, and the combination that give the best results for growth of top grafting in durian. The research was conducted in November 2018 to January 2019 in Alasmalang Village, Kemranjen, Banyumas. The experiment was a pot experiment with a factorial design. The treatment was a combination of growth regulator (control, bean extract, coconut water, IBA, and BAP) and number of scion leaves (2, 4, and 6 strands). The research design used was a RCBD with 15 treatments and three replications. The results showed that the treatment of PGR IBA and BAP had a significant effect on the number of grafted shoots of durian plants, namely 2.711 and 2.822 and the treatment of the number of leaves of two leaves had a significant effect on shoot break time, the number of shoots and the increase in the number of grafted leaves of durian plants, namely amounting to 2.3 strands.","PeriodicalId":420744,"journal":{"name":"Jurnal Hortikultura","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129888872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Penelitian ini bertujuan mengidentifikasi karakteristik industri dan merancang upaya perbaikan rantai pasok bahan baku keripik kentang industri rumah tangga di Jawa Barat. Penelitian dilaksanakan di Garut dan Pangalengan, Jawa Barat pada bulan Agustus 2016. Pengumpulan data dilakukan melalui metode survey dan focus group discussion (FGD). Survey dilaksanakan melalui wawancara 19 responden prosesor keripik kentang skala rumah tangga. Focus group discussion diarahkan untuk mengelaborasi kondisi aktual dan potensi perbaikan rantai pasok bahan baku keripik kentang. Alat analisis yang digunakan adalah statistika deskriptif, analisis strengths, weaknesses, opportunities, and threats (SWOT,) matriks strategic position and action evaluation matrix (SPACE), dan analisis quantitative strategis planning matrix (QSPM). Hasil penelitian menunjukkan bahwa rata-rata pasokan bahan baku per industri adalah 2,8 ton per bulan. Sistem pembelian bahan baku adalah spot market. Kapasitas produksi keripik kentang per bulan berkisar antara 15–540 kg (84,2%). Spesifikasi bahan baku masih belum terstandarisasi dan bersifat ekstrinsik kualitatif. Analisis SWOT dan pemetaan faktor-faktor eksternal-internal menunjukkan bahwa perbaikan rantai pasok dapat ditempuh dengan menggunakan strategi agresif. Penyusunan prioritas strategi melalui analisis QSPM menyarankan agar strategi promosi masif varietas alternatif kentang prosesing non-Atlantik (termasuk Median) dan kemudahan akses petani terhadap benihnya, serta strategi perbaikan sistem pembelian bahan baku dapat diimplementasikan secara simultan.KeywordsKeripik kentang; Industri rumah tangga; Rantai pasok bahan baku; Analisis kekuatan-kelemahan-peluang-ancamanAbstractOne important factor that could maintain production sustainability of agro-processing industry is the availability of raw material. The study was aimed at examining potato chips household industry characteristics and designing strategies to improve the raw material supply chain in West Java. The study was conducted in Garut and Pangalengan in August 2016. Data collection was carried out through survey of 19 household industries. Meanwhile, FGD involving relevant participants was conducted to elaborate household industries’ existing conditions and potentials for improvements. The analytical tools used were descriptive statistics, analysis strengths, weaknesses, opportunities, and threats (SWOT),  strategic position and action evaluation (SPACE) matrix, and quantitative strategic planning matrix (QSPM) analysis. The results showed that the industry was characterized by average raw material demand of 2.8 tons/firm/month, spot market purchasing system, and production capacity of 15–540 kg/month.
