Abstract. Purba JH, Sasmita N, Komara LL, Nesimnasi N. 2019. Comparison of seed dormancy breaking of Eusideroxylon zwageri from Bali and Kalimantan soaked with sodium nitrophenolate growth regulator. Nusantara Bioscience 11: 146-152. Eusideroxylon zwageri is a very strong and durable wood, which can be used as building materials. This wood plant needs 6-12 months to germinate, but it can be shorted with special treatment (e.g. cracking). Therefore, it is important to conduct research to stimulate E. zwageri seed germination using sodium nitrophenolate growth regulator. The purpose of this study was to analyze the comparison of the fastest time to breaking E. zwageri seed dormancy from the Bali and Kalimantan island. The research method was factorial randomized block design, using the X factor (soaking time) and Y factor (sodium nitrophenolate growth regulator). There were four soaking time treatment, i.e., immersed (soaked in a really short time), 12 and 24 hours soaking time. While the Y factor was the concentration of sodium nitrophenolate with 4 treatments: without sodium nitrophenolate solution or 0 mL (control), soaked in a 1 mL/L of water, 2 mL/L of water and 3 mL/L of water solution. The study results showed the best treatment of E. zwageri seeds germination speed was soaked for 24 hours, and by giving 0,3% sodium nitrophenolate concentration, while the interactions of both showed no significant effect. The soaked time treatment, sodium nitrophenolate concentration, and the interaction of both show no significant effect on germination percentage. The breaking of E. zwageri seed dormancy from Kalimantan has a shorter time to germinate than E. zwageri seeds from Bali.

Abstract. Purba JH, Wahyuni PS, Zulkarnaen, Sasmita N, Yuniti IGD, Pandawani NP. 2020. Growth and yield response of shallot (Allium ascalonicum L. var. Tuktuk) from different source materials applied with liquid biofertilizers. Nusantara Bioscience 12: 127-133. This research was to examine growth and yield of shallots using different sources of propagation material, namely true shallot seed (TSS) and bulbs. Soil biological fertility, which was generally low, was improved by the addition of liquid organic fertilizer. The purpose of this study a) to determine the differences in the propagation of plants from seeds and bulbs of shallot Tuktuk varieties, and b) to determine the effect of liquid biofertilizer maxigrow and rhizobacteria. The study used a one-factor randomized design. The results showed that the growth and yield of shallots propagated with bulbs were better than the origin of the seeds. The treatment of the two types of liquid biofertilizer produces tangible growth and yield, but there was no significant difference between the two kinds of liquid organic fertilizer.

Abstract

Urban farming has emerged as a strategic response to the challenges of land scarcity and food security in metropolitan areas. This study investigates the financial performance and internal marketing value of shallot (Allium cepa var. aggregatum) agribusiness cultivated hydroponically using Nutrient Film Technique (NFT) and Deep Flow Technique (DFT) systems across two planting cycles. Conducted as a case study at P4S Galih Jaya, the research employed a quantitative descriptive approach, combining direct observation, financial documentation review, and structured stakeholder interviews. Key metrics, production output, net income, Benefit-Cost (B/C) ratio, and Break-Even Point (BEP), were calculated using standard agribusiness financial formulas. Internal marketing indicators, including employee understanding, decision alignment, and motivation, were assessed through pre- and post-cycle surveys and integrated into participatory training sessions. Results indicated that the DFT system in cycle 2 yielded the highest net income (IDR 2,036,725) and B/C ratio (3.6), while the NFT system in cycle 1 incurred a financial loss (IDR -10,155) with a B/C ratio of 0.9. These findings were embedded into internal communication tools and stakeholder training sessions to foster data-driven decision-making. Internal marketing indicators showed marked improvement between periods, demonstrating the strategic value of integrating financial literacy into agribusiness operations. The study concludes that the selection of a hydroponic system not only affects profitability but also internal stakeholder engagement. The comparative study framework offers a replicable model for urban farmers seeking to align technical performance with internal adoption and strategic planning. Further research is recommended across successive planting periods to assess long-term viability and deepen internal marketing impact.
