Abstract

Public discussion of the Criminal Procedure Code Bill (RUU KUHAP) on X forms user-to-user relations that can be examined as a communication network. This study maps the #RUUKUHAP network structure and identifies actor positions using Social Network Analysis (SNA). Data were collected through Selenium-based web scraping, producing 654 records that were pre-processed into a directed graph. NetworkX was used to calculate density, reciprocity, modularity, in-degree, out-degree, betweenness centrality, and eigenvector centrality, while the network was visualized using a PyVis Force Atlas 2-based layout. The final graph contained 85 nodes and 79 edges, with density 0.0111, reciprocity 0.0506, modularity 0.8758, and 18 communities. @Haikal88651720 had the highest out-degree (11), while @kemenkum, @KPK_RI, @febridiansyah, and @TodungLubis shared the highest in-degree (4). Betweenness values were generally near zero. The network is sparse, strongly partitioned into communities, and weakly reciprocal; however, these structural findings alone do not establish ideological polarization or echo chambers without content and stance analysis.

Abstract

Public network services require a disturbance-monitoring process that connects customer reports, fault identification, technician assignment, and status updates in a structured workflow. This study analyzes WiFi.id disturbance-report monitoring using the Network Operation Support System Assurance (NOSSA) application at PT Telkom Regional I Sumatera. The study is positioned as a descriptive analysis based on documented workflows, service topology, ticket processes, and application interfaces available in the source manuscript. The analysis shows that NOSSA is used to display customer data, identify disturbance states such as AP DOWN, forward information to operational staff or field technicians, and record maintenance activity until the status is updated. This workflow reflects integrated ticketing and service-assurance functions at the operational level. However, the source manuscript provides no dataset on ticket volume, response time, resolution time, escalation rate, reopened tickets, or SLA achievement. Consequently, NOSSA effectiveness cannot yet be quantified. The study contributes a process map and identifies performance indicators required for subsequent evaluation.

Abstract

Perioperative hypothermia can be aggravated by the administration of low-temperature intravenous fluids, creating a need for controlled warming and monitoring. This study develops an Internet of Things (IoT)-based infusion fluid warmer prototype using a NodeMCU ESP8266, DHT11 sensor, 5 V DC relay, STC-1000 digital thermostat, an incandescent lamp as the heating element, and the Blynk application. A Research and Development approach was applied through circuit design, programming, prototype construction, thermal testing, and connectivity testing. The prototype used a 39-40°C control band, with the heater switched off at 40°C and reactivated at 39°C. Across seven initial conditions of 26.3-31.6°C, the recorded time to reach 40°C ranged from 5.7 to 21.45 minutes. NodeMCU connectivity tests at 1-10 m remained connected, with 0-second recorded delay at 1-9 m and 1 second at 10 m. The results demonstrate basic control and monitoring functionality; however, clinical suitability cannot be concluded because outlet-fluid temperature, sensor accuracy, long-term stability, electrical safety, and patient testing were not validated.

Abstract

Dust accumulation on photovoltaic surfaces can reduce incoming irradiance, making surface maintenance an important part of PV operation. This study develops an Internet of Things (IoT)-based solar panel cleaning robot prototype using a NodeMCU ESP8266, ultrasonic sensors, drive motors, a cleaning mechanism, and a 12 V power supply. The development process included hardware design, programming, cleaning-process testing, and distance-sensor validation. On a panel described in the source manuscript as “2 meters,” the cleanliness status changed from “dirty” at minutes 1–2 to “moderate” at minutes 3–5 and “clean” at minute 6, while the recorded system voltage remained 12 V. Ultrasonic-sensor measurements from 10 to 100 cm produced a mean absolute error of 1.3 cm and an MAPE of approximately 2.97% against ruler measurements. The results demonstrate basic navigation and cleaning functions. However, cleaning effectiveness on PV performance cannot yet be established because electrical output, dust mass, cleaned area, path completion, and IoT communication performance were not quantitatively measured.
