Abstract

The production of Cocoa in Indonesia is still relatively low, reached an average of 532.17 kg ha-¹, while Ivory Coast has reached 1.5 tons ha-¹ in 2013. One of the efforts to support the development of the cocoa plant is a breeding use of organic fertilizers, Vermicompost is an organic fertilizer that has a lot of nutrients and safe for plants and contains many microorganisms that needed land. While of effort to improve the performance of microorganisms in the soil by terralyt-plus. The research was conducted at the experimental farm of the Faculty of Agriculture and Animal Husbandry, University of Muhammadiyah Malang with an altitude of 560 meters above sea level, which held for 3 months. Research compiled using factorial randomized design consisting of two (2) factors. The first factor is vermicompost consists of 3 levels, namely: D0 = 0g/plant; D1 = 200g/plant and D2 = 400g/ plant. The second factor is Terralyt-plus comprises 3 levels: T0 = 0 ml/polybag, T1 = 20 ml/polybag, and T2 = 40 ml/polybag continued BNJ test with a level of 5%. Vermicompost fertilizer dosage of 400g/plant with the addition of Terralyt-plus 40ml / plants is the best treatment in all parameters of the cocoa plant (Theobroma cacao L.). Results from this study are in treatment plant height, a number of leaves and total leaf area were significantly different interactions occur while the stem diameter and the amount of chlorophyll there is no real interaction.

Abstract

This study evaluated the interaction between mushroom species (ear mushrooms and oyster mushrooms) and growing media (with the addition of coffee peels) on mushroom growth and yield. The results showed that oyster mushrooms were superior to ear mushrooms in various parameters, including mycelial growth, time to first primordia emergence, harvest wet weight, and dry weight. The use of media with the addition of 20% coffee skin showed good results, with significant mushroom growth and yield. This research was conducted at the Production Unit of the Integrated Land Biotechnology Development Center, Faculty of Agriculture and Animal Husbandry, Muhammadiyah University of Malang from November 2019 to January 2020. This research used an experimental method with two types of mushrooms and three different compositions of growing media. The results of data analysis showed significant differences between treatments, with oyster mushrooms showing better results than ear mushrooms. These results can be a guideline for oyster mushroom cultivation by utilizing coffee skin waste as an effective growing medium.

Abstract

The study conducted at the Integrated Laboratory of the Faculty of Agriculture and Animal Husbandry, University of Muhammadiyah Malang, aimed to formulate granule and liquid biofertilizers for corn cultivation on dry land in Indonesia, covering 144.47 million hectares. Corn is a crucial agricultural commodity in the country, aligning with the Sustainable Food Self-Sufficiency Policy program. Fertilizers, especially biological ones with plant growth-promoting rhizobacteria (PGPR), play a pivotal role in enhancing both the quality and quantity of corn production. The research utilized a Nested Split Plot Design, considering varying levels of drought stress (100%, 70%, and 40% of field capacity) and bacterial density (control, 10^9, 10^8, and 10^7). Results indicated no significant interaction between granular and liquid fertilizer densities across different field capacities. While the PGPR consortium in both fertilizer types showed limited effectiveness in boosting maize growth and yield, the highest average performance was observed at a density of 10^7. Additionally, certain stress levels did not contribute to increased maize growth and yield, except for the 100% field capacity treatment. It was noted that extreme temperatures, reaching up to 54°C in the plastic house, might have hindered the expected interaction. Plant growth tends to decrease drastically below 15°C or above 40°C, as these temperatures activate physical and chemical processes in plants. The study underscores the importance of considering environmental factors in optimizing biofertilizer effectiveness for sustainable corn cultivation on Indonesian dry land.

Abstract

The study conducted in Cikajang District, Garut Regency from February 20 to June 15, 2023, aimed to assess the impact of different compositions of organic mulch, derived from water hyacinth and banana stems, combined with a blend of chicken and cow manure on lettuce growth and yield. Employing ANOVA analysis at a 5% significance level, with a DMRT follow-up test, the research involved seven treatments and two controls. The treatments included organic mulch without manure mixture (M1), and organic mulch with 5% (M2), 10% (M3), 15% (M4), 20% (M5), 25% (M6), and 30% (M7) cow and chicken manure. Positive control was Black Silver Plastic Mulch, and negative control was without mulch. The study revealed significant effects of organic mulch treatments on plant height, leaf count, and crop diameter during the initial vegetative growth stage. Specifically, treatment M5, comprising organic mulch from water hyacinth with a 20% mixture of cow and chicken manure, demonstrated a notable increase in net head weight per plot at harvest. This suggests the potential of this particular mulch composition for enhancing lettuce yield. The findings emphasize the practical application of organic mulch, particularly M5, as a beneficial strategy in lettuce cultivation, promoting growth and ultimately increasing harvest yield.

Abstract

Functional food is increasing along with the increasing number of people with degenerative diseases and the elderly population, the development of commercial products, scientific evidence of the benefits of functional food components, and the development of food technology. The purpose of this research is. The research was conducted in Tegalgondo Village, Karangploso District, Malang Regency, East Java Province. The research was conducted in March – June 2022. The research was arranged in a Split-Plot Design consisting of 4 main plots (PGPR Concentration) and 4 subplots (crosses). Based on the results, it was concluded that there was an interaction between the administration of PGPR and the reciprocal cross of Pulut-purple corn x sweet corn on the observation of sugar content characters. PGPR treatment with PGPR concentration of 45 ml/l water (V45) can increase growth and yield characteristics. The results of the reciprocal crosses (JPUM) of pulut-purple corn♀ x sweet corn and (JMPU) sweet corn♀ x pulut-purple corn showed that the female parent was more dominant than the male parent.
