Blockchain is the core technology used to create cryptocurrencies, such as Bitcoin. As one part of the fourth industrial Revolution since the invention of steam engines, electricity, and information technology, blockchain technology has begun to be applied in areas such as finance, judiciary, and trade. Blockchain technology uses decentralized, distributed and transparency techniques for data security. This research aims to determine the implementation of blockchain technology in the field of education, especially in the Data Security section. The study uses two methods namely the mind mapping method and literature review. The results of this study showed that with the presence of blockchain technology, the data is more secure from attacks from both inside and outside because it passes through two levels of security, namely encryption and decentralized data.

At present, the process of validating documents for certain purposes cannot be done face-to-face because of the Covid-19 pandemic. Therefore, this research aims to maximize the existence of smart digital signature technology that guarantees its safety and validity without having to meet face to face. Encrypted digital signatures with RSA-SHA256 with cloud storage features that can share documents. The waterfall method for building systems, the collection of data generated for analysis by observation, and online questionnaires using Google Form.  Based on the characteristics of the system, the satisfaction factor analysis of the system with the Slovin formula processed by the SUS score resulted in a score of 95 > 70. The final result of this study is that the digital signature system has a significant impact on increasing motivation to facilitate authorization and secure documents.

Cloud computing is a technology that utilizes the internet services using a central server with the goal of maintaining a virtual nature of data and applications. The presence of cloud computing will obviously lead to changes in the workings of information technologysystems within an organization. This is because the concepts of cloud computing through virtualization, standardization and other fundamental features can reduce information technology costs, simplify the management of information technology services, andaccelerating service delivery. In general, cloud computing architecture consists of: (1) Infrastructure as a Service (IaaS), (2) Platform as a Service (PaaS), and (3) Software as a Service (SaaS). Characteristics of cloud computing are: (1) self-service (on demand self service), (2) broadband access (broadband access network), (3) clustered resource (resource pooling), (4) elastic (rapid elasticity), and (5) measured service (measuredservice). While the advantages of cloud computing is: (1) without any initial investment, (2) convert CAPEX into OPEX, (3) flexible and easily developed, (4) focus on the business, rather than information technology, and (5) of control and responsibility of service. Withcloud computing consumers free themselves from the responsibility for managing the stack of computing resources. Levels ranging from SaaS when it is completely free, PaaS while still must make an application, and IaaS are still busy with the operating system. Thiscontrasts with On-Premise to take care of all your own.

Giving rewards for good performance and achievement of tasks needs to be done as a form of recognition and appreciation by the organization/institution to employees, as well as being part of the process of achieving organizational goals. This study aims to develop a Decision Support System that uses the Technique for Order of Preference by Similarity (TOPSIS) method with the PHP programming language to select reward recipients at University. The data used came from 2 groups, namely educational staff (lecturers) and non-educative staff (employees). Determination criteria applied to the educative group are 10 things, namely: tenure, DP3 value, the value on the percentage of work attendance, value on the percentage of teaching attendance, value on lecturer functional position, value on research implementation, the value on implementation of community service, value on the results of the questionnaire by students, the value of employment status, and the value of sanctions. There are 5 determinant criteria used in the non-educative group, namely: tenure, DP3 value, percentage of work attendance, the value of employment status, and value of sanctions. The results of this study are in the form of an information system program as a decision-making tool for the process of selecting reward recipient employees.

Journal Publications in STMIK Raharja is a facility for students and lecturers in conducting research, the CICES Journal is one of the journals in STMIK Raharja, which was published 1 year 2 times in February and August, the problem that occurs is the absence of an online journal google scholar indexed, and there was no information summary to make a decision and the difficulty of the prospective writer getting information about the CICES journal. To overcome this problem, a research was carried out which developed a system for improving the governance of CICES journals on published quality and quality by using SWOT analysis and the Statistical Product and Service Solutions (SPSS) method which were felt to be able to assist in data management. then transformed in the form of iMe in STMIK Raharja, is expected to overcome the existing constraints, by providing information that supports the decision-making system in Journal Publications. This system was created in collaboration with Rinfo, Rinfo Sheet, Rinfo Form and iLearning Media which are part of the 10 IT STMIK Raharja Pillars. which is then implemented for the needs of journal publications on STMIK Raharja through web cices.ilearning.me.

In a scientific work, it is closely related to a writing management. Writing which is a writing activity is inseparable in the learning process. Writing can also be used as a management communication tool in conveying information. There are 4 (four) written communication elements as media tools. But recently a new paradigm has begun to develop that a management of scientific work does not have to be based on scientific research, but also a study of a problem that is analyzed professionally by experts. With the method of description using 5 (five) principles in the management of scientific writing to solve problems. So writing management is needed in compiling scientific papers in order to create good work by following the development of the industrial era 4.0. Thus, the task of intellectuals and intellectuals is not only able to read, but also must be able to manage writing about scientific writings and master the procedures for preparing scientific works. Utilization of Management of Writing Scientific Writing in the Learning Process in Higher Education. Keywords: management of scientific work, management of writing, scientific work.

Lette is one of the sub-districts in Mariso Subdistrict, Makassar City which has a suburban area and the community has a livelihood as a fisherman. The condition of the Tanjung Bunga coastal and coastal area has undergone a change, which used to be the territorial waters that are now largely transformed into land, this change is due to the ongoing coastal and coastal reclamation process in the area of Tanjung Bunga. To meet the need for urban space, Lette fishermen have no choice but to be relocated from their place of origin to the flats. This study aims to determine the spatial, cultural, socio-economic changes in the fishing settlement of Lette and the factors that drive these changes. This study uses an inductive-qualitative method with a phenomenological approach. The results of the study show that the changes that occur are changes in coastal space, changes in settlement space and the creation of a central business, tourism and entertainment area. Factors driving these changes are changes in fishing boat access and entry, dock circulation, catching areas that are not potential, domestic activities, spatial space utilization, bale-bale culture, informal fishing activities, and new economic space.
