Gen SMT 1 merupakan gen kunci didalam biosintesis hormon brasinosteroid yang berperan dalam pertumbuhan dan pertambahan batang tanaman. Teknik yang digunakan untuk mengidentifikasi gen yang memiliki karakter unggul tersebut adalah PCR (Polymerase Chain Reaction). Dalam proses PCR, desain primer merupakan hal yang sangat penting karena primer tersebut akan menentukan keberhasilan dalam proses amplifikasi PCR. Tujuan dari penelitian ini untuk mendapatkan kandidat primer yang akan digunakan dalam analisis keragaman genetik terkait pertambahan tinggi batang berdasarkan situs SNP. Data sekuen DNA kelapa sawit diperoleh pada laman NCBI. Pensejajaran sekuen DNA dilakukan pada sofware geneious prime untuk mengidentifikasi situs SNP. Desain primer dilakukan pada perangkat lunak WebSNAPER. Hasil penelitian menghasilkan dua kandidat pasang primer yang akan digunakan untuk melakukan analisis keragaman genetik terkait gen pengendali pertambahan tinggi batang melambat. Masing- masing primer terdiri dari primer reference dan alternate dan memiliki ukuran amplikon yang berbeda pada setiap pasang primer. The character of growth inhibitor stem is one of the goals of oil palm plant breeding to increase the economic life of the plant, reduce the replanting cycle and simplify the harvesting process. The SMT 1 gene is a key gene in the brasinosteroid hormone which plays a role in the growth and addition of plant stems. The technique used to identify genes with superior characters is PCR (Polymerase Chain Reaction). In the PCR process, the design of the primer is very important because the primer will determine the success of the PCR amplification process. The aim of this study was to obtain primer to be used in the analysis of genetic diversity related to stem height gain. Oil palm DNA sequence data were obtained in terms of NCBI. DNA sequence alignment was performed on geneious prime software to obtain SNP sites. Primer design was performed on WebSNAPER software. The results of the study obtained two candidate pairs of primers to be used for the analysis of genetic diversity related to the increase in the height of the stems of the stem. Each primer consists of reference and alternate primers and has a different amplicon size for each pair of primers.","PeriodicalId":122744,"journal":{"name":"MEDIA PERTANIAN","volume":"71 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139196867","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 dilakukan di Kebun Percobaan Fakultas Pertanian Universitas Siliwangi Kampus Mugarsari Kecamatan Tamansari Kota Tasikmalaya pada bulan April sampai Juli 2022. Penelitian ini menggunakan Rancangan Acak Kelompok dua faktor yang diulang sebanyak 3 kali dengan dosis inokulum Rhizobium sebagai faktor pertama yaitu (i0 = kontrol, i1 = 10 g kg-1 dan i2 = 15 g kg-1), dan faktor kedua dosis vermikompos yaitu (v0 = kontrol, v1 = 10 t ha-1 dan v3 = 20 t ha-1). Analisis data menggunakan variansi dengan uji F dan uji lanjut menggunakan uji jarak berganda Duncan pada taraf signifikansi 5%. Hasil penelitian menunjukkan tidak ada interaksi antara inokulasi Rhizobium spp. dan vermikompos pada pembentukan bintil akar dan hasil kacang tanah. Secara mandiri inokulasi Rhizobium spp. berpengaruh terhadap semua parameter, sedangkan vermikompos berpengaruh terhadap jumlah polong, jumlah polong bernas, bobot polong bernas basah, bobot polong bernas kering per tanaman, dan hasil polong per petak.  Fertilization is one of the intensification efforts to increase peanut yields. Peanut are less responsive to nitrogen fertilizer due to existence of Rhizobium. It provides nitrogen for plant by fixing N2 from the atmosphere. The aims of this study is to determine the interaction between the doses of Rhizobium inoculum and vermicompost on the root nodules formation and peanut yield. This study was conducted at the Experimental Garden of the Faculty of Agriculture, Universitas Siliwangi, Mugarsari Campus, Tamansari District, Tasikmalaya on April to July 2022. This study used 2 factors randomized block design which was repeated 3 times with the dose of Rhizobium inoculum as the main factor (i0 = control, i1 = 10 g kg-1 and i2 = 15 g kg-1), and the second factor was the dose of vermicompost (v0 = control, v1 = 10 t ha-1 and v3 = 20 t ha-1). Data analysis used variance with the F test and follow-up test using Duncan's Multiple Range Test at a significance level of 5%. The results showed that there was no interaction between Rhizobium spp. inoculations and vermicompost on the root nodules formation and peanut yields. Independently inoculated Rhizobium spp. affected all the parameters. Meanwhile vermicompost affected the number of pods, the number of pithy pods, the weight of the wet pithy pods, the weight of the dry pithy pods per plant, and the yield of pods per plot.","PeriodicalId":122744,"journal":{"name":"MEDIA PERTANIAN","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123487159","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}
