Abstract

Bigo Live is a broadcast application in the form of the most popular live streaming video for IOS and ANDROID operating systems with the number of users in Indonesia reaching 10 million users. This research was carried out using the mixed method, which combines qualitative and quantitative methods. The case study of this study was carried out in 2 locations covering Indonesia, namely Medan and DKI Jakarta. The results showed that there was a significant impact between Pornography and Porn Content Action on Bigo Live on Child Morality in Indonesia. The picture of deviant morality in adolescents in Indonesia shows that there are deviant behaviors, although it is dominated by the light deviant behavior of 53 respondents (68.8%). Thus the results are accepted, so it can be said that the cultivation theory of exposure to mass media towards changes in the behavior of viewers is proven to have an effect between the frequency of watching pornography and pornography on Bigo Live social media on the deviant (sexual) morality of teenagers in Indonesia. Research implications, it is expected for teachers, parents, guardians and community leaders from the results of this study to be used as an evaluation material to build the personality of adolescents and teachers and lecturers always provide information to students to use the internet only for positive things. The existence of this research is expected to be one of the considerations for Bigo Live's Social Media to be disciplined again, by adding an automatic and applicable filter system for users who abuse Bigo Live's social media applications so as not to damage the morality of Indonesian children.

Abstract

Phosphate is an essential nutrient for plant growth and development. However, most of the phosphate in the soil is in a form that is not directly available to plants. In increasing the availability of phosphate in the soil, more environmentally friendly microbes such as Rhizobia sp. One interesting approach is through the interaction between plants and bacteria Rhizobia sp. Recent research has shown that Rhizobia sp. can also have an important role in increasing the utilization of phosphate by plants. Rhizobia sp has the ability to produce phosphatase enzymes. The role of Rhizobia sp in increasing the utilization of phosphate in plants, it is hoped that more effective methods can be found in increasing the availability of phosphate and optimizing the use of phosphate resources in agriculture. The purpose of this research is to understand in depth the role of Rhizobia sp in increasing the utilization of phosphate by plants. This research was conducted at the Experimental Field of the Nusantara Technology University. The research method used in this study was a randomized block design with 2 variables, namely liming and isolates of Rhizobia sp. The results showed that the application of Rhizobia sp isolate had a significant effect on P levels and P uptake of soybean plants. Isolate Rhizobia sp. the best was treatment I9 (BGR 3), thus the isolate was effective in increasing the availability of phosphate and could be absorbed by plants effectively. Giving Rhizobia sp can increase phosphorus indirectly due to interactions between plants and Rhizobia sp. which produces the enzyme phosphatase.

Abstract

The high phosphate retention in Andisols causes the availability of P to be low, can not be absorbed by plants. Actinomycetes are capable of solubilizing bound phosphates. This research aimed to identify Actinomycetes in Andisols Namanteran, assess their ability to increase phosphate availability, and understand how they work to increase phosphate availability in this soil. The research design used a factorial randomized block design with 2 factors; factor 1 was Actinomycetes isolate, consisting of A₀ = No Inoculant, A₁ = Inoculant A₁₃₂ (vegetable crops; 32 × 10⁸ CFU mL⁻¹), A₂ = A₄₆₈ (forest plants; 41 × 10⁸ CFU mL⁻¹), A₃ = A₄₅₈ (forest plant; 58 × 10⁸ CFUmL⁻¹), A₄ = A₄₇₁ (coffee plant; 35 × 10⁸ CFU mL⁻¹), A₅ = A₄₅₉ (forest plant; 63 × 10⁸ CFU mL⁻¹), A₆ = A₃₂₁ (hibiscus plant; 37 × 10⁸ CFU mL⁻¹), and A₇ = A₃₅₆ (vegetable plant; 33 × 10⁸ CFU mL⁻¹), and factor 2 was soil water content, consisting of K₁ = 50%, K₂ = 75% and K₃ = 100% of field capacity. The results showed that the availability of P in Andisols increased due to the application of Actinomycetes from 42.46 ppm to 159.20−266.60 ppm. The population of Actinomycetes in Actinomycetes treatment ranged from 27.33−31.58 × 10⁸ CFU mL⁻¹), with a soil pH of 4.41. Water content of 100% was the best in increasing soil pH and Actinomycetes population, but not having significant effects on the available P of the soil. The results of molecular identification of Actinomycetes that have the best potential in dissolving P include A₃>A₅>A₂>A₄>A₁.

Abstract

This study investigates the potential of Black Soldier Fly (BSF) larvae in managing organic waste through rapid decomposition and nutrient-rich compost production. The primary objective was to evaluate the efficiency of BSF larvae in waste reduction and compost quality, particularly within urban environments, and to explore their scalability in urban waste management systems. The methodology involved controlled experiments to measure bioconversion rates at varying larval densities, temperature, and moisture levels. The compost produced by BSF larvae was analyzed for key nutrients, including nitrogen, phosphorus, and potassium. The results demonstrated that BSF larvae effectively reduced organic waste by up to 86% within a few days, outperforming traditional composting methods. The compost produced was rich in essential nutrients, making it suitable for urban farming. Factors such as optimal larval density, temperature, and moisture content were crucial for maximizing decomposition efficiency and compost quality. However, the study also identified several challenges, including space constraints, public perception, and the logistical difficulties of scaling BSF larvae systems in urban areas. In conclusion, this research highlights the potential of BSF larvae as a sustainable solution for organic waste management, compost production, and urban farming. The findings contribute to the growing knowledge on sustainable waste management and urban agriculture, offering insights into integrating BSF larvae systems into existing waste management frameworks. Future research is needed to address scalability challenges and optimize the operational efficiency of BSF larvae systems in urban environments.
