Salah satu cara alternatif yang efisien dan efektif untuk mengatasi cekaman garam yaitu dengan menggunakan varietas yang toleran terhadap cekaman garam dengan agen seleksi yaitu NaCl. Penelitian ini bertujuan untuk menentukan tingkat konsentrasi NaCl yang toleran terhadap anggrek bulan dan menentukan tingkatan resistensi anggrek bulan terhadap cekaman garam (NaCl) secara in vitro. Rancangan percobaan pada penelitian ini menggunakan Rancangan Acak Lengkap dengan 5 taraf konsentrasi NaCl 0 % ; 0,25 % ; 0,50 % ; 0,75 %, dan 1 % pada medium Vacin and Went. Parameter yang diamati yaitu, persentase jumlah planlet, visualisasi planlet, tinggi, jumlah daun, indeks stomata, berat basah, kandungan klorofil, dan indeks resistensi cekaman garam. Data kuantitatif dari setiap parameter dianalisis dengan menggunakan Analisis Ragam pada taraf nyata 5% dan uji lanjut dengan Uji Tukey pada taraf nyata 5%. Hasil penelitian menunjukkan bahwa tingkat konsentrasi NaCl 0,25% sampai 0,50% yang ditoleransi oleh tanaman anggrek bulan secara in vitro terdapat pada kisaran 0,25-0,5 dikategorikan cekaman sedang, sedangkan konsentrasi NaCl 0,75% sampai 1% terdapat pada kisaran 0,5-1,0 yang dikategorikan cekaman berat dan tingkatan resistensi anggrek bulan seluruh konsentrasi adalah resistensi moderat.\u0000 \u0000Kata kunci: cekaman garam, NaCl, Phalaenopsis amabilis (L.)

The experimental design of this research used completely randomized design with 5 concentration level NaCl 0%; 0,25%; 0,50%; 0,75%; and 1% in Vacin and Went medium. Parameters observed were plantlet percentage, plantlet visualization, height, number of leaves, stomata index, wet weight, chlorophyll content, and salt stress resistance index.

The aims of this study was to find the diversity of the large ruminants in Java in the 8th century based on the reliefs at Borobudur Temple. The research was conducted by observing various large ruminant images contained in the reliefs of Borobudur Temple. The results of the observations were interpreted and clustered based on their morphological characteristics. The results showed that there were ten relief panels containing images of cattle and nine relief panels containing images of buffalo.

Sintesis AIA ini memerlukan senyawa tambahan berupa triptopan. Namun beberapa bakteri mampu memproduksi AIA tanpa penambahan prekursor. Penelitian ini bertujuan untuk memperoleh isolat bakteri penghasil hormon AIA dari tanah Kebun Raya Liwa. Pada ini diawali dengan isolasi bakteri tanah asal Kebun Raya Liwa, selanjutnya dilakukan uji kemampuan produksi AIA secara kuantitatif tanpa penambahan triptopan. Pengujian produksi AIA secara kualitatif dilakukan dengan menggunakan media Nutrien Broth dengan metode spektrofotometri dengan penambahan reagen salkowsky dan dilakukan pengamatan setelah 72 jam inkubasi.

The goal of this study was to obtain isolates of AIA hormone-producing bacteria from the soil of the Liwa Botanical Gardens. This begins with the isolation of soil bacteria from the Liwa Botanical Gardens, then a quantitative test of AIA production capability is carried out without the addition of tryptophan. Qualitative testing of AIA production was carried out using Nutrien Broth media with spectrophotometric methods with the addition of Salkowsky reagent and observations were made after 72 hours of incubation. The data obtained are presented in tabular form. The results showed that 9 isolates were able to produce the AIA hormone at different levels.

One of the important nutrients in supporting fertility and plant growth is phosphate. The amount of dissolved phosphate in the soil that can be utilized by plants is very small, causing a deficiency. Indigenous phosphate solubilizing bacteria are needed to meet the needs of phosphate for plants. The purpose of this study was to obtain isolates of phosphate solubilizing bacteria that have the potential to dissolve phosphate. This research was carried out from March to June 2021 covering the isolation of phosphate solubilizing bacteria and testing the potential for dissolving phosphate on solid pikovskaya media. Potential phosphate solubilizing bacteria were determined based on the highest Phosphate Solubility Index (IPF) value. The results of soil isolation from Liwa Botanical Gardens obtained 10 isolates capable of dissolving phosphate and producing a clear zone. Isolates with the best phosphate solubilizing potential were isolates C1 and C3 with phosphate solubilizing index values of 2, 6 and 2.\u0000 \u0000 \u0000 \u0000\u0000\u0000\u0000","PeriodicalId":123546,"journal":{"name":"Jurnal Ilmiah Biologi Eksperimen dan Keanekaragaman Hayati (J-BEKH)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133419372","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}
