The Effect of Growth Regulator Substance on Shoot Cutting of Jamblang (Syzygium cumini (L.) Skeels

Development of jamblang (Syzygium cumini) as medicinal plant currently constrained by the aspects of cultivation technology (vegetative propagation), so the provision of medicinal plants for the mass scale was very difficult. The objective of this research was to evaluate the effect of five doses of  growth regulator substance on growth of S. cumini’s shoot cuttings. The active ingredient composition of hormone/ Growth Regulator Substance (GRS) in this study were Naphthalene Acetic Acid (NAA) 3 percent and Naphthalene Acetamide (NAAm) 0.75percent. The experiment was arranged in Completely Random Design using 5 concentrations of growth regulator substance namely 0g.10ml-1(control), 2g.10 ml-1, 4g.10ml-1, 10g.10ml-1 and powder (not dissolved). The results of this experiment proved that  4g.10 ml-1of growth regulator substance produce the highest height growth (29.84 cm or 21.74 percent increment), the highest number of leaves (23.72 pieces or 4.63 percent increment), the heaviest dry weight of stem and leaves (3.36 gram or 43.59 percent increment) and the highest top-root ratio (6.55 or 10.08 percent increment). The highest survival percentage was resulted from GRS powder treatment (80 percent or 18.81 percent increment), but did not significantly different to GRS treatment of 4g.10 ml-1 (77.33 percent). The application of 4g.10 ml-1 is recommended to use to produce the better growth of cuttings planted on soil

Shott) under three species stands using  agroforestry system in community forest siteAbstractTaro (Colocasia esculenta L. Shott ) is a functional food plant. Based on Permenhut P.35/2007 with regard to Non Wood Forest Product, taro is categorized as a starch plant. According to the knowledge of local people, the agroforestry of taro has been applied on dry land of private forest. The objective of this research was to evaluate the growth and productivity of taro under three tree species of the private forest using agroforestry system. Survey and field observation were conducted in this research. Agroforestry systems were observed on sengon+taro, jabon+taro, manglid+taro, and monoculture of taro as a control. Growth and production of taro plants were measured, including height growth, number of leaves, wet and dry weight of leaves and stems. Wet and dry weight of tuber were recorded to calculate the taro production. Tree species showed significant effects on growth and production of taro plant in agroforestry system. The highest biomass of taro (366.57 g/plant) was found under jabon species, followed by sengon (266.15 g/plant), manglid (175.64 g/plant), and taro monoculture (182.98 g/plant), respectively. The light intensity under jabon tree in agroforestry system was 41.17%. The highest production of wet and dry weight of taro tuber were 2,333.0 g/plant and 884.3 g/plant, which was resulted under jabon stands, followed by under sengon stands (1,597.0 g/plant and 535.7 g/plant), under manglid stands (607.6 g/plant and 213.6 g/plant) and monoculture (739.4 g/plant and 256.3 g/plant), respectively.

COVID-19 Pandemic: Impacts, Craftsmen’s Living Strategies, and Economic Recovery of Bamboo Handicraft Enterprise in Gunungkidul, Indonesia

The COVID-19 pandemic has affected the household bamboo handicraft industry in rural areas. A comprehensive study was conducted to identify impacts, living strategies, and economic recovery; the findings will be used as a basis to recommend supporting policy to create a more resilient bamboo handicraft business. This study applied phenomenological approach to interpret the social impacts of the COVID-19 pandemic. In December 2021, 30 bamboo craftsmen in Semin Village, Gunungkidul, Yogyakarta Special Province were interviewed. Results show that 96.7% of bamboo craftsmen experienced a decrease in profit, with 46.6% reporting no order for a long period. The profit earned by craftsmen decreased by 76.50%. Bamboo craftsmen adapted to the COVID-19 pandemic by minimizing capital expenses, creating innovations marketing in options (i.e., direct sales, selling online) and focusing on alternative income sources (farming, hunting and gathering, selling food, and becoming laborers) to survive. As the spread of the virus was controlled, leading to the relaxation of restrictions on economic activities, the bamboo industry in Semin has entered an economic recovery phase. Currently, the average profit has reached 66.18%, compared to the profit earned in normal pre-pandemic situation. We believe the government should facilitate craftsmen to build their capacity in e-commerce, export mechanism, market network creation, tool acquisition, and English proficiency. This would enhance the bamboo handicraft industry in Semin to be more resilient facing future challenge

Germination of Jamblang (Syzygium Cumini) Seeds on Three Treatments of Pre-Germination and Sowing Media

Generative propagation was needed as one of efforts in developing jamblang as a medicinal plant. This study aims to improve the percentage and germination rate of jamblang seeds through pre-germination and sowing media treatments. The combination of treatments were (1) soil (T) x water (AB), (2) soil (T) x coconut water (AK), (3) soil (T) x control (without soaking treatment) (K), (4) sand (P) x water (AB), (5) sand (P) x coconut water (AK), (6) sand (P) x control (K), (7) mixed soil-sand (TP) x water (AB), (8) mixed soil-sand (TP) x water (AB), and (9) mixed soil-sand (TP) x control (K). The results revealed that the treatments of sowing seeds with mixed media soil + sand and pre-germination treatments by soaking the seeds for 12 hours in coconut water gave the highest percentage (70%) and germination rate (4.96%). Percentage of germination more than 50% only can be reached by the seeds that sowed on mixed soil + sand with pre-germination treatments soaked in coconut water for 12 hours and in water for 12 hours. The improvement in the percentage and germination rate of jamblang were achieved by using mixed sowing media soil + sand and pre-germination treatment by soaking in coconut water
