-Individuals Owned Enterprises as a partnership can possibly develop and create in the event that it can adjust to essential business law. Business begins from advertise that implies no market, no business. In this way, People-Owned Enterprises model methodology starts with advertise the board both broadly and universally or exchange as a significant exertion to deal with a powerful market. It is the business as well as enormous scope business that decides the nature of crude material supplies sourced from makers (rancher gatherings, anglers, skilled workers, and so on.), which is facilitated in the structure and the executive’s arrangement of People-Owned Enterprises. Individuals Owned Enterprises as an establishment of monetary entertainers will empower expanded creation and efficiency as the premise of monetary development and comprehensive money related which is solid and reasonable. A comprehensive economy and account lifts individuals or society from the base of the pyramid position. The nation’s financial strategy and even governmental issues have not been benevolent to the general public. In addition, the limit of neighborhood authorities to manufacture a comprehensive people’s economy is still constrained. Other than physical and non-physical framework including the board abilities from the legislature and nearby networks is restricted.

Abstract
This study aimed to determine the effect of rice straw compost and rice husk ash on some chemical properties of an Ultisol soil under sweet corn plant. This study was conducted at the Labuhan Batu Rantau Prapat University Campus Land and the PT. Socfindo Laboratory. The design used in this study was a randomized factorial design consisting of two factors with two replications. The first factor was the application of rice husk ash with four dose levels (g 5 kg-1 of soil), i.e. P0 (0), P1 (10), P2 (20), and P3 (30). The second factor was the application of rice straw compost with four dose levels (g 5 kg-1 of soil), i.e. J0 (0), J1 (25), and J2 (50), J3 (75). Results of this study indicated that the application of rice straw compost significantly increased soil organic-C and available P contents, as well as plant height, plant dry weight, N and P uptake by the plant. The treatments, however, did not significantly increase soil pH and total-N content. The application of rice husk ash significantly increased soil organic-C content and N uptake by the plant, but it did not significantly increase pH, available P content, and total N content of the soil.

Abstract
Maize is a cereal commodity that has an important role in supporting food security and food
diversification programs. The application of organic and inorganic fertilizers is one of the efforts to increase national maize productivity. This study was aimed to explore the effect of the application of organic and inorganic fertilizers on N, P and K uptake by maize in an Ultisol. Treatments tested were combinations of five levels of organic fertilizer application (0%, 100%, 75%, 50%, and 25% of recommended organic fertilizer dose), and five levels of inorganic fertilizer (0%, 100%, 75%, 50%, and 25% of recommended inorganic fertilizer dose). The twenty-five treatments were arranged in a factorial randomized block design with two replications. Results of the study showed that there was a relationship between N, P and K uptake by maize with maize shoot dry weight, root weight, and shell weight. The highest plant height, shoot dry weight, and root dry weight of the maize were obtained by the treatment of 100% of organic fertilizer. The highest maize shell dry weight and uptake of N, P was obtained by the in the treatment of 75% organic fertilizer.

Abstract
There are three main things to survive in a change: tri-strategy, namely reorientation, restructuring, and alliance. In every business organization, management usually puts these three management strategies to survive any difficulties. Nowadays, the management of public organizations, or governments, or the bureaucracy must learn from the business sector in order to maintain its function and – again – be able to create value to society.This trilogy is actually a derivation of “reinventing” or “reengineering”. The principle is that defending yourself by only maintaining efficiency and effectiveness is not enough. Government organizations need “adaptive capacity”. Focusing solely on efficiency and effectiveness is like how to fight the last war. After we know how to do that, we find that the next war is quite different-and that we are not prepared for it.

 Abstract

This study aims to determine the response of robusta coffee plant nurseries to Arbuscular Mycorrhizal Fungi and chicken manure. This research was carried out in the experimental garden of the Indonesian Community Development University. This research was conducted in July and ended in September 2019. This study used a randomized block design (RBD). There are two factors studied, namely Arbuscular Mycorrhizal Fungi and Chicken Cage Fertilizer. The first factor was giving Arbuscular Mycorrhizal Fungi (C) with 4 treatment levels, namely C0 = 0 g / plant, C1 = 10 g / plant, C2 = 20 g / plant, C3 = 30 g / plant. The second factor is the provision of chicken manure (A) consisting of 4 levels of treatment, namely: A0 = 0 tons / ha, A1 = 5 tons / ha, A2 = 10 tons / ha, A3 = 15 tons / ha. The parameters observed were seed height, number of leaves, stem diameter, root length, number of roots, and root wet weight. The results showed that the treatment of arbuscular mycorrhizal fungi had a significant effect on seed height, root length, and root wet weight, but had no significant effect on the number of leaves, stem diameter, and number of coffee seedlings until the age of 15 WAP. The higher the arbuscular mycorrhizal dose that was given up to 30 g / plant, the higher the seeds were 23.10 cm, the roots were about 13.95 cm long, and the wet weight of the roots the heavier was about 11.95 g. Chicken manure treatment had a significant effect on seed height, root length, and root wet weight, but had no significant effect on the number of leaves, stem diameter, and number of root seedlings of coffee seedlings up to the age of 15 WAP. The higher the dose of chicken manure given up to 15 tonnes / ha, the taller the coffee seeds are about 23.18 cm, the roots are about 13, 98 cm long, and the weight of the wet roots is about 11.65 g. The interaction of arbuscular mycorrhizal fungi treatment with chicken manure had no significant effect on seed height, number of leaves, stem diameter, root length, number of roots, and root weight.
