Abstract

Rhizobia fixed nitrogen from the air and supplied legume and effected to soil fertility. The research was conducted in May 2017 until November at Soil Biology Laboratory and Screen House of Agriculture Faculty University of Sumatera Utara. This research was carried out with 2 stages: growth test at various pH with isolate tested (TJA 1, TJA 2, TJA 3, BGR 1, BGR 2, BGR 3, BGR 4, BALAI 1, BALAI 2, BALAI 3, LP 1, LP 2, LP 3, LP 4 and LAB) and the infectivity test and the effectivity of Rhizobia. The research used Randomized Block Design with 2 treatment: Lime (Without Lime and Lime 1 x Aldd) and Isolate Rhizobia (TJA 1, TJA 3, BGR 1, BGR 3, BGR 4, BALAI 2, BALAI 3, LP 1, LP 2, LP 4 and LAB). The application of Rhizobia’s isolate BGR 3 showed the infektively with root nodule amount criteria(124,00). The isolate Rhizobia’s BGR 3 effectively increased N plant level and N absorption (3,80 %; 31,08mg/plant). Application of isolate Rhizobia was not able to increase the level of P plants and P plant uptake. The best interaction was shown (Plant height 85.00 cm, stem diameter 3.93 mm, root nodule 127.50, N level of 3.80%, N absorption 30.16 mg / plant) by treatment of BGR 3 and Lime 1 x Aldd.

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

Organic waste management presents a significant challenge for many communities, especially in the agricultural and livestock sectors. The increasing amount of organic waste, particularly in urban areas, has led to environmental issues such as landfill overflow, methane emissions, and pollution. As an innovative solution, the use of Black Soldier Fly (BSF) larvae has proven effective in converting organic waste into animal feed and organic fertilizers. This study aims to develop a community-based training program focusing on the utilization of BSF larvae for organic waste management and the production of value-added products. The implementation method includes identifying suitable locations, designing the training program, and providing post-training support to participants. Results show that participants successfully applied BSF farming techniques using local organic waste, producing high-quality animal feed and organic fertilizers that enhanced agricultural productivity. Additionally, this technology reduced feed costs, lessened dependence on chemical fertilizers, and minimized the volume of waste disposed of in landfills. The discussion highlights challenges related to infrastructure and the availability of quality organic waste. The main conclusion of the study is that BSF farming provides a sustainable solution that can improve food security, reduce environmental impacts, and strengthen local economies through community empowerment.

Abstract

The community service that has been implemented in Lubang Buaya Village, Cipayung District, in 2023, aims to stimulate the use of used bottles as an innovative solution in overcoming the food crisis and strengthening local food security. This effort is in line with government initiatives to develop domestic food security and reduce dependence on food supplies from abroad. In addition, research and development related to urban farming practices using used bottles in Cipayung plays an important role in providing practical guidance to local communities to start and run urban farming practices effectively. This step is expected to help city residents produce their own food sustainably, reduce the burden of food imports, and improve community food security. Throughout the program, a continuous evaluation phase has also been conducted. This allows monitoring the long-term impact of this activity, including the improvement of the quality of life of the local community. In conclusion, this community service program has successfully improved participants' knowledge, skills, and insights related to the basic principles of hydroponic plant cultivation. It has also stimulated business development on a household scale and contributed to the improvement of the surrounding environment.
