The demand of purple eggplants increased significantly every year, but it is often not matched by an increase in production caused by poor cultivation. The increased production can be achieved through several efforts, one of which is fertilization with organic materials. This research aims to determine the optimal combination and concentration of each treatment for the application of liquid organic fertilizer (LOF) and biological fertilizer which can provides the best influence on plant growth and yield of purple eggplant.&nbsp;<strong>Methods:</strong> This research used a completely randomized design (CRD) consisting of 2 factors. The first factor was the concentration of liquid organic fertilizer (N) divided into 3 levels, consists of 0 ml/l (N0), 4 ml/l (N1), and 8 ml/l (N2). The second factor was the concentration of bio-fertilizer (P) divided into 4 levels, consists of 0 ml/l (P0), 10 ml/l (P1), 20 ml/l (P2) and 30 ml/l (P3). <strong>Results: </strong>The result indicated that the concentration of 8 ml/l LOF and 30 ml/l bio-fertilizer was able to increase the number of leaves, total flowers per plant, total fruits per plant, and total fruits fresh weight per plant.&nbsp;<strong>Conclusions:&nbsp;</strong>This Research can be concluded that the concentration of 8 ml/l LOF and 30 ml/l bio-fertilizer gave the best effect on purple eggplants.</p> Arsarizky Arief Didik Utomo Pribadi Ramdan Hidayat Copyright (c) 2024 BIOEDUSCIENCE https://creativecommons.org/licenses/by/4.0 2024-08-31 2024-08-31 8 2 146 153 10.22236/jbes/14552 Application of Biopesticide Fobio Against Moler Disease (Fusarium oxysporum) on Three Varieties of Shallots in Probolinggo City https://journal.uhamka.ac.id/index.php/bioeduscience/article/view/14435 <div> <p class="6abstracttext"><strong>Background: </strong>Shallots (<em>Allium Ascolonicum </em>L)<em>. </em>is a seasonal crop that is widely grown by farmers intensively. Although the demand for productivity of this crop continues to increase, domestic production is still not enough to meet market demand because shallots are a seasonal crop. The low productivity of onion plants can be influenced by various factors, one of which is <em>Fusarium attack</em>, which if not controlled can cause crop failure. The use of chemical pesticides to control <em>Fusarium </em>sp. often causes dependence and pollution, so alternative controls are needed. The purpose of this study was to determine the potential of Fobio Biopesticide against three onion varieties in increasing growth and reducing the intensity of <em>Fusarium </em>sp. attack.<strong>Method: </strong>The method used is RAKF with a factor of 1 consisting of three varieties of shallots (Biru Lancor, Tajuk, and Batu Ijo), factor 2 in the form of farmer treatment and concentration levels of Biopesticide Fobio 5 and 10 ml / l. <strong>Results: </strong>The results showed that treatment with a concentration of Biopesticide Fobio 5 ml / l and Blue Lancor varieties was able to increase the best results in various variables such as plant height, wet weight, dry weight, disease intensity, and incubation period. <strong>Conclusion: </strong>Based on the research that has been done, it can be concluded that Fobio Biopesticide has the capacity to increase the resistance of onion plants to moler disease.&nbsp;Treatment with Biopestiisda Fobio concentration of 5 ml / l in the Lancor Blue onion variety showed the best results in various variables compared to other treatments, it was shown an increase in plant height up to 5 – 6 cm, wet weight up to 2.8 g / tuber, dry weight up to 1.7 g / tuber, disease intensity up to 8% at 42 HST, and the longest incubation period up to 23 days.</p> </div> <div> <p class="6abstracttext"><em><strong>Keywords: </strong></em>Shallot, Biopesticide Fobio, <em>Fusarium </em>sp.</p> </div> Yola Salsabila Shafa Sri Wiyatiningsih Endang Tri Wahyu Prasetyawati Copyright (c) 2024 BIOEDUSCIENCE https://creativecommons.org/licenses/by/4.0 2024-08-30 2024-08-30 8 2 169 176 10.22236/jbes/14435 The Effect Of Coconut Water, Onion Extract and Bamboo Boobs Extract on Robusta Coffee Seed Germination (Coffea canephora) https://journal.uhamka.ac.id/index.php/bioeduscience/article/view/14419 <p><strong>Background: </strong>Robusta (<em>Coffea canephora</em>) is one type of coffee widely cultivated in Indonesia and is one of the leading commodities. Coffee seeds include seeds that have a long dormancy period that inhibits the germination process. Breaking dormancy can be done by several methods, one of which is soaking in natural growth regulators. Soaking treatment with natural growth regulators can be combined with soaking time treatment to break dormancy. This study aimed to determine the combination of natural growth regulator treatment and the right soaking time for Robusta coffee seed germination. <strong>Methods:</strong> This research is a 3-repeat Complete Factorial Randomized Design Experiment with the first factor of natural growth regulators type, which consists of 4 levels, namely: Z0 = control; Z1 = coconut water; Z2 = onion extract and Z3 = bamboo shoots, and the second factor is the length of soaking which consists of 3 levels, namely P1 = 12 hours; P2 = 24 hours and P3 = 36 hours. <strong>Results:</strong> Natural growth regulators' treatment of shallot extract with 24 hours of soaking time gave the best results on all parameters. <strong>Conclusions:</strong> Using natural growth regulators from coconut water, shallots, and bamboo shoots with several soaking times affects all parameters observed, both in single and combined administration.</p> Aldila Putri Selsha Kirani Didik Utomo Pribadi Nova Triani Copyright (c) 2024 BIOEDUSCIENCE https://creativecommons.org/licenses/by/4.0 2024-08-31 2024-08-31 8 2 234 243 10.22236/jbes/14419
