Abstract
Malapari has great potential to produce biofuel, and is known as an energy source plant that many stakeholders are developing. The Malapari planting program needs information related to germination and how to produce seedlings that are ready for planting, have vigor, and can adapt to the planting area. This research aims to determine the effect of treatment with ultrafine bubbles (UFB) water and dark septate endophytes (DSE) fungi, which are invigoration technologies to increase the viability and vigor of malapari seeds and seedlings. The research design used a completely randomized factorial design with two factors, namely treatment of soaking seeds with UFB water with doses consisting of 0, 8 ppm, and 20 ppm, and DSE treatment using without DSE, DSE Dendrothyrium sp., DSE Cladophialophora nyingchiensis, and DSE Exophiala pisciphila. The results showed that malapari seed moisture content of 9.36% gave a high germination percentage, then the soaking of UFB water, which was not an effective method to be used. Giving DSE Exophiala pisciphila fungi to the seeds could maintain their germination percentage and improve the germination rate. In addition, it accelerates the mean of germination days and mean daily germination, furthermore, the seedling were studied more, resulting the higher seedling quality.

Abstrak
Malapari memiliki potensi yang besar untuk menghasilkan minyak nabati, dan dikenal sebagai tanaman sumber energi yang sedang dikembangkan oleh banyak pihak. Program penanaman jenismalapari perlu didukung informasi perkecambahan dan pembibitan untuk menghasilkan bibit yang siap tanam, vigor dan mampu beradaptasi di lahan penanaman. Penelitian bertujuan untuk menganalisis efektivitas pemberian air ultrafine bubbles (UFB) dan cendawan dark septate endophytes (DSE) sebagai salah satu teknologi invigorasi g meningkatkan viabilitas dan vigor benih, serta bibit malapari. Rancangan penelitian menggunakan faktorial dalam rancangan acak lengkap dengan dua faktor, yaitu faktor perendaman benih dengan UFB water terdiri 3 taraf (dosis 0 sebagai kontrol, 8 ppm, dan 20 ppm) dan faktor DSE 0,1% terdiri 4 taraf (kontrol, DSE Dendrothyrium sp., DSE Cladophialophora nyingchiensis, dan DSE Exophiala pisciphila). Hasil penelitian menunjukkan bahwa benih malapari
dengan kadar air 9,36% masih mempunyai daya berkecambah yang tinggi sehingga tidak efektif diberi perlakuan perendaman dengan UFB. Benih malapari yang diberi cendawan DSE E. pisciphila bisa mempertahankan daya berkecambah benih dan dapat meningkatkan kecepatan perkecambahannya. Cendawan DSE E. pisciphila juga mempercepat rata-rata hari berkecambah, meningkatkan perkecambahan harian, bibit lebih kokoh, dan indeks mutu bibit lebih tinggi
