Abstract

Banyak fenomena-fenomena di kehidupan nyata dapat diinterpretasikan ke dalam model matematika yang diformulasikan secara matematis dan membentuk suatu persamaan diferensial. Persamaan diferensial biasa pada umumnya mempunyai orde bilangan bulat. Persamaan diferensial yang berorde pecahan disebut persamaan diferensial fraksional. Salah satu persamaan yang sering digunakan dalam kehidupan nyata yaitu persamaan diferensial Riccati. Pada penelitian ini, penulis akan mencari solusi dari persamaan diferensial fraksional Riccati menggunakan metode Dekomposisi Adomian Laplace dan analisis kekonvergenannya. Metode ini mengombinasikan antara transformasi Laplace dan dekomposisi Adomian. Sehingga, akan didapat kesimpulan bahwa barisan orde dari sebuah persamaan diferensial fraksional Riccati yang konvergen ke suatu bilangan akan mengakibatkan barisan fungsi solusi dari persamaan diferensial fraksional Riccati tersebut konvergen ke fungsi solusi persamaan diferensial fraksional Riccati dengan ordenya adalah bilangan itu sendiri.

Abstract

Simple hydroponic technology plays a role in increasing human capacity and capacity to deal with the impacts of climate change and contribute to sustainable development. Dealing with the impacts of climate change means reducing significantly or eliminating negative effects on society and the natural environment, this activity can be started through simple things such as reforesting the immediate environment in the community. The principle of sustainable development is an important guide to ensure that the use of simple technologies such as hydroponics to reduce climate change by recycling materials also has an impact on increasing the ability of future generations to meet their own needs. I Green Project, We Grow Communityis a community service initiated by LPPM Universitas Informatics and Bisnis Indonesia in collaboration with the International Student Organization AIESEC focuses on the role of academics in mitigating climate change by adopting actions to mitigate the impacts of climate change. Because climate and environment are interrelated, this community service also considers the role of hydroponics as greening the environment in helping individuals understand the environment around them, which is a prerequisite for overcoming the problem of climate change. Pengabdian located in Baranang Siang, Bandung City, West Java, 2018 has provided an understanding of the steps needed to reduce climate change, including several policy issues that need to be addressed, changing environmental conditions to be greener and activating community participation to have additional income from the program. Hydroponics so that people with weak economies are more helped to be independent. This program is implemented for 1 month in August with the number of community members as executors of 30 (thirty) people.

Abstract

In Indonesia the delaying of electronic ID card recording and rareness of E-ID card raw material mostly happened for past two years. This situation shown there’s implementation failure. Government acceleration of procurement policy has been released but still doesn’t solve the main problem itself. The delivery of blank ID card doesn’t spread evenly, many Indonesian citizen have to wait for more than 1 (one) year only for their electronic ID card being recorded and printed. For citizen this become disadvantages, there’s no proper supply chain management in delivering this blank ID from central government to province, city or district. Based on the phenomenon, the researcher aims to research whether the procurement policy, implementation of electronic ID card recording and its impact on Indonesia public trust or not. The analysis of the research problem is based the theory of policy implementation of Edwards in Subarsono (2005: 90) [1], theory effectiveness approach by Mahmudi (2005: 92) [2] adapted from Steers (1985: 53) [3] and for trust based by theory Flavian dan Giunaliu (2007) [4]. Methods used in this research are explanatory while the source and method for data collect use questionnaire and simple random sampling. The data was processed with partial least square. Result of this research showed a positive and significant impact of The Procurement Policy, Effectivity Implementation of Electronic ID card Recording on Citizen Trust. Thus the hypothesis proposed in this study was tested with PLS-SEM. Result shown procurement policy impact directly on citizen trust with path value 0,2882 greater than path value indirect impact through effectiveness implementation as much as 0,1765.
