The distribution of water and the billing of user consumption remain a major difficulty that the Régie de Distribution d’Eau of the Democratic Republic of Congo, REGIDESO in acronym, has been trying to overcome for several years, because this does not allow the Congolese State to maximize revenue on the one hand, and on the other hand, users are victims of over-invoicing, classified in the category of flat-rate invoicing, given that REGIDESO has no effective means of management of water distribution and users. In the context of the province of Lualaba, in the city of Kolwezi which presents a fast demographic growth, and which knows many problems related to the management of water consumption, this study relates to the installation of a system of distribution and monitoring of water consumption using Internet of Things sensors to control and manage installations remotely.

Currently, the clocking of agents in public companies in the DRC and in particular in the province of Lualaba remains one of the areas that require a lot of attention from managers because the manual clocking that is done to date in Lualaba revenue department, does not allow to maximize the productivity of the company given that the agents who constitute the main workforce, come to the service always in delays sometimes exaggerated for lack of a mechanism of control of the time of arrival of the agents at the service following a clocking in which is done on a sheet where all the agents personally complete the time of arrival at the service and the time of departure, sometimes by filling in the wrong information. Then, exits from the company’s facilities are not controlled, an agent can leave the workplace as many times without a valid reason and for an unacceptable period, which causes several agents to abandon their posts during working hours. because the existing system cannot accurately determine when an agent comes into the office and when an agent leaves the office. The existing system does not know how to manage the cases of absence of agents either, because certain agents can sign the presence on behalf of the other absent agents, which leads the company to pay even the absent ones, which causes a problem of payroll management which takes into account the number of days worked, handicapping the productivity of the organization given that human resources constitute the basic workforce of this department. The use of RFID electronic badge clocking nevertheless remains an effective solution for solving the problems of agent clocking management.

Currently, the DRC wants to be an important place in agriculture, it has set up several support structures for farmers, more particularly in the province of Haut-Katanga. Despite all these efforts, this agriculture is still facing several difficulties related to global warming which has disrupted the usual short rainy season, which forces vegetable gardeners to re-examine the traditional irrigation system taking into account the requirements of each culture. It is in this context that our study will focus on the automation of the irrigation system in the context of market gardening.

After a long observation and analysis the process of receiving and sending mail, we opted the computerization the system for managing internal and external mail of the public sector company that is the subject of our study, which is the General Directorate of Customs and Excise of Haut Katanga, in the Democratic Republic of the Congo. This phase explains the ultimate concern that motivates us to conduct research in a given environment while explaining the rationale for choosing this study to meet the needs of the DGDA/DRC. The major concern that motivated us to approach this study is none other than to see the DGDA properly manage its mail, thanks to a computer tool consisting of a database that it can update daily. This study would be useful to companies with managerial character to hold well their management on the mail in the concern to ensure the perenniality of the data and to fight against the waste of time in the search and the location of the old mail.

The choice of this study theme is related to the object that attracted our attention as scientific researchers. It all started with an exchange and observation of the functioning of the control and payroll service of the teachers of the province of Haut-Katanga (SECOPE in the acronym), so we were driven by the desire to improve the process to allow good management and the smooth running of the operations related to the transfer of the agents as well as their pay. This study will serve to bring a computerized solution to the Ministry of Education and more precisely to the service of control and pay of the teachers by a management tool based on the functioning of the process of transfer of the agents and to better manage these last ones to maximize the receipts. This work has led to the following results (Know the number of all agents for a given period in relation to their task, Quickly exchange data between different positions involved, Make each agent’s information accessible through a shared database that offers better data storage and access techniques while eliminating the loss of records of all transferred agents).

The stimulus of our choice in this study, remains the observation made at the time of the declaration of the tax on the rental income by various taxpayers. The present work was beneficial to us taking into account first of all our scientific orientation and the desire to set up a better-computerized solution to palliate the administrative difficulties of the Directorate of the Revenues of Haut-Katanga (DRKAT in the acronym) to provide to the various services the possibility to communicate between them without moving, to carry out operations in the fiscal field of tax collection on rental income by the integration and implementation of a computer tool within the concerned services, which will allow the reduction of the greatest number of risks that this process of tax collection on rental income runs. This implemented system will include computer resources that will allow users to collect, process, save on removable media and share data without running many risks. The development of a computer tool that will allow proper monitoring by the Directorate of Revenue of Haut-Katanga for the collection and payment of rental income tax.

The approach to new information and communication technologies spares no area of ​​life; road surveillance is one of the activities that requires special attention given the significant increase in the number of motor vehicles in circulation involving regular checks of on-board documents by elements of the traffic police.In the context of the town of Kolwezi in the Democratic Republic of Congo where we observed numerous traffic jams caused by elements of the Road Traffic Police who, to identify the vehicles in order with the on-board documents, they must check for each vehicle stopped piece by piece, and this causes delays for the drivers in order who sometimes undergo the same check several times in a day at several checkpoints, to this is added the hassle during the check, which causes many incidents on the road. public highway.Thus, through this study, we are proposing the computerization of the road traffic police service to solve the problems related to the control of on-board documents.

The Geographic Information System ranks among the flagship tools in the approach of new information and communication technologies, and this in land management which, currently, is at the center of several studies especially with the document digitization project. Cadastral in the Democratic Republic of Congo. In the context of the province of Haut-Katanga, through its land division of Haut-Katanga which presents a rapid demographic growth, and which knows a lot of requests for land which sometimes cause land conflicts following spoliations, encroachments and attributions multiples of the plots to several applicants following the mismanagement of the subdivisions which does not guarantee the security of the title deeds. To respond to land management concerns, we are proposing through this study the Geographic Information System and its means of implementation to assess the degree of resolution of land disputes.
