“…Soaking using HCl obtained germination, the height of seedlings, and long roots with the maximum average. Strong acid solutions such as HCl are often used with varying concentrations depending on the seed needed, making the coat soft [16][17][18]. The administration of HCl given to sugar palm seeds caused a speedy increase in the percentage of germination growth [19][20].…”

Palm oil is a dormant plant. The main cause of oil palm seed dormancy is the hard and thick seed coat or shell, inhibiting the effective absorption of water and gases. The presence of a seed coat barrier causes the germination process of oil palm seeds to be hampered. This study aims to determine the effect of chemical treatment on breaking palm oil dormancy by immersion in a solution of strong acids, namely H2SO4, KNO3, and HCl. This study used a completely random design (CRD) with three treatments, four observations, and five replications. The results of the following study were analyzed using MANOVA with the parameters observed were germination rate, germination rate, seedling height, and most extended root length. Based on the analysis results, it was found that immersion with a solution of a strong acid, namely H2SO4, KNO3, and HCl, had different effects on breaking palm oil dormancy. The highest average germination rate was through immersion with HCl, which produced an average of 65.24. The highest average germination was through immersion in H2SO4 with an average of 8.52. In contrast, the average seedling height and most extended root length were soaked in HCl with an average of 35.28, and 15, respectively. Based on the results obtained, the best chemical treatment for breaking palm oil dormancy is through soaking with HCl.

“…Hasil uji BNT pada Tabel 1 juga menunjukan bahwa perendaman benih aren dalam larutan KNO3 konsentrasi 0.5% menghasilkan persentase yang lebih tinggi yaitu sekitar 76%. Menurut (Nengsih, 2017) larutan KNO3 mampu berinteraksi dengan suhu sehingga dapat merangsang dan menstimulir perkecambahan benih. Hasil penelitian (Lasut et al, 2022) yang melakukan perendaman benih aren dalam larutan KNO3 dengan konsentrasi 1%, 1.5%, 2%, dan 2.5% tidak berpengaruh nyata terhadap persentase perkecambahan dengan persentase yaitu sekitar <11%.…”

Sugar palm (Arenga pinnata) is one of the non-timber forest product that has many benefits and still had high economic demands, therefore it is necessary to be cultivated and due to the farmers still utilizing sugar palm stands that grow naturally. The cultivation of sugar palm is so difficult to be done because there was no efficient and effective technology that can break the dormancy problem yet. The objective of this research was to determine the effect of sanding and seeds submersion in various concentration of KNO3 to break the dormancy of sugar palm seeds. The experiment was performed in Greenhouse of Agriculture Faculty of Mataram University from June to September 2015. The experiment was conducted in 2x3 factorial experiments on Completely Randomized Design (CRD) with five replications. First factor was sanding (A): A1 = without sanding dan A2 = sanding and second factor was submersion in various concentration of KNO3 (N): N1 = 0.4%, N2 = 0.5%, and N3 = 0.6%. Results of this study indicated that both treatments gave significant effect in breaking the dormancy of sugar palm seeds. Sanding and submersion in 0.5% KNO3 resulted in single significant effect on all parameters except embryonic axis. The interaction between both treatments only showed significant effect on rotten seeds.

Kopi memiliki masa dormansi yang cukup lama karena memiliki kulit biji yang keras, sehingga perkecambahan membutuhkan waktu lama. Salah satu upaya untuk mempercepat masa dormansi benih kopi adalah menggunakan benih matang secara fisiologi dan aplikasi cendawan endofit. Penelitian ini bertujuan untuk mengetahui tingkat kematangan buah dan jenis cendawan dapat mempercepat perkecambahan dan pertumbuhan benih kopi. Penelitian ini disusun menggunakan Rancangan Acak Kelompok (RAK) dengan 2 perlakuan yaitu tingkat kematangan buah (berdasarkan warna buah kopi) dan jenis cendawan endofit. Tingkat kematangan buah kopi (warna kulit buah kopi) terdiri atas 4 taraf yaitu: buah kopi berwarna cokelat, merah, orange dan kuning. Faktor kedua yaitu jenis cendawan endofit dengan 2 taraf yaitu: isolate CE-1, isolate CE-5, dan sebagai tanpa perlakuan. cendawan endofit sebagai kontrol. Parameter yang diamati adalah persentase kecambah (%), pecahnya kotiledon (hari), daun Lembaga terbuka sempurna (hari), munculnya daun pertama (hari), tinggi bibit (cm), jumlah daun (helai), panjang akar (cm), bobot segar tanaman (gr), bobot segar akar (gr), bobot sekar daun (gr), bobot kering tanaman (gr), bobot kering akar (gr), bobot kering daun (gr). Hasil penelitian menunjukkan bahwa tingkat kematangan buah kopi berpengaruh nyata terhadap persentase kecambah, munculnya daun pertama dan bobot segar tanaman. Tingkat kematangan buah terbaik untuk persentase kecambah adalah warna merah dengan persentase kecambah 98,5%, munculnya daun pertama (44 hari), dan bobot segar tanaman (0,25 gr). Jenis isolate cendawan endofit berpengaruh nyata terhadap persentase kecambah, daun lembaga terbuka sempurna dan munculnya daun pertama. Jenis cendawan endofit CE-5 menunjukkan hasil terbaik pada parameter persentase kecambah (93,06%), daun lembaga terbuka sempurna (28 hari) dan munculnya daun pertama (46 hari). Penggunaan buah kopi berwana merah dengan aplikasi cendawan endofit dapat digunakan untuk meningkatkan perkecambahan dan pertumbuhan bibit kopi.
