Adapting IMOI for Information Systems: Toward a Cyclical and Mediated View of System Design
No full textThe Input–Process–Output (IPO) framework has long guided organizational and Information Systems (IS) research. While valued for its clarity, IPO reduces process to a black box and treats outputs as final rather than cyclical, limiting its usefulness in dynamic IS environments where iteration and socio-technical integration are essential. This paper conceptually adapts the Input–Mediator–Output–Input (IMOI) model, first developed in organizational science, for IS system design. A layered comparison with IPO, data flow diagrams (DFDs), and CRUD logic situates IMOI within the IS development stack, and the conceptual analysis is supported by a case vignette of a university mobile system. IMOI reframes process into three families of mediators (technical, cognitive, and affective) that can be observed, measured, and adjusted across cycles. Outputs, including prototypes, user analytics, and stakeholder feedback, are explicitly treated as inputs for subsequent iterations. The findings suggest that IMOI preserves IPO’s clarity while adding diagnostic depth and cyclical adaptability. By emphasizing mediators and feedback, IMOI offers a stronger conceptual foundation for designing, evaluating, and governing modern information systems

No full textThe DKI Jakarta and Banten Load Management Implementation Unit is one of the load control areas in the Java Bali system which participates in load regulation and has 10 subsystems. However, in the current conditions, the Gandul 1.3 - Muarakarang - Kembangan 2 subsystem has several system vulnerabilities. the most transmitted is on the Durikosambi-Kembangan cable channel which has an OCR setting of 1100 A (800 A limitation related to cable capacity and cable age factor at the request of the asset owner). This channel is the main route connecting the Muarakarang generator with IBT Gandul and IBT Kembangan2. For the Durikosambi IBT defense setting scheme, it uses the setting pattern that was previously applied to the Durikosambi-Kembangan SKTT with the same load target, only commissioning from the Durikosambi-Kembangan SKTT to Durikosambi IBT 1 and 2, with it being two new subsystems, there is no need to worry anymore about taking on Durikosambi-Kembangan SKTT so that electricity services can be optimal and the No Outage Zone can be maintained properly. With the operation of GISTET Durikosambi, the operational pattern for the Muarakarang Power Plant has changed, namely Muarakarang Block 1 and PLTU Muarakarang 4-5 can be positioned on standby (Reserve Shutdown). So the generating unit operating is only in Muarakarang Block 2 with an assumed operating pattern of an average of 680 MW in 24 hour

Desain Aplikasi Biaya Sebagai Penetapan Tarif Praktek Bidan Swasta
No full textAs long as this fee has not been calculated on a unit cost basis, the rates for midwives differ from one to another, even though they are in the same area. Tariff calculation is only based on the price of goods prevailing in the market. As a result of these differences in rates, people tend to choose private practicing midwives who provide lower rates for the same type of service. The practice of private midwives has not yet calculated the unit cost as the basis for setting tariffs. The purpose is to find out whether the rates currently used are appropriate or not with the unit cost. The data collection technique uses case studies because it only involves one partner unit, namely the midwife. The data collected was then analyzed through descriptive qualitative, namely explaining and explaining the conditions of partners in implementing the excel application regarding practice rates. The location of the community service partner at Midwife Anggraeni Linda Silfyani A.Md.Keb at Babakan Ciparay Bandung. After attending this training, private practice midwives were able to formulate a tariff pattern based on the unit cost that would be used at their practice site. From the explanation above, this dedication to the community is entitled Design Cost Application as the Basis for Determining Tariffs for Private Midwife Practice. From the community service that is carried out, it is hoped that it can minimize problems from partners and become a pilot project for other midwives who have the same problems
