Abstract

The use of heavy equipment in construction work has become a key solution to improving project execution efficiency and effectiveness. One critical phase in construction is excavation for substructure elements such as tie beams and pile caps, which require precision and speed during implementation. This study discusses the application of a mini excavator for substructure excavation work in the Paddle Court development project located at Plaza 6 Pondok Indah. The aim of the study is to evaluate how far the mini excavator can offer advantages in terms of time, cost, labor, and accuracy of the work compared to conventional manual methods. The methodology includes direct field observation, visual documentation, and qualitative analysis of productivity and challenges encountered during implementation. The results show that using a mini excavator can accelerate execution time by up to 60% and significantly reduce labor needs. However, challenges such as limited maneuvering space in tight areas and the need for strict supervision to maintain excavation accuracy were also identified. These findings form the basis for recommendations to contractors in selecting excavation methods based on site conditions, project capacity, and time urgency. Therefore, the use of a mini excavator is an effective solution to enhance project productivity, particularly for large-volume substructure work in areas with adequate working space. This research is expected to serve as a technical reference for similar future construction projects.

Abstract

Criminal Law has the characteristics of a double-edged sword, because on one side it protects the victim but on the other side deprives the rights of the perpetrators. Therefore, the settlement of cases through criminal lines becomes ultimum remidium because Criminal Law is used as a last resort in solving criminal cases. One form that emerges today is the Penal Mediation effort which is used as a form of settlement of criminal cases, especially for insignificant crimes. The paper analyzes and looks deeper into the implementation of penal mediation at the Police level, in the Semarang City Police Department. The research uses an empirical juridical method with a research location in the city of Semarang. The research underlines that in the implementation of media penalties at the police level is carried out through a Progressive Law framework. In its implementation, the police must base on the principle of conflict resolution, process-oriented, and the process is informal. One of the penal mediation forms implemented and applied by Semarang City Police Department is on domestic violence cases, where the principle that is put forward is Victim Offender Mediation. This study concludes that the implementation of media penal is one form of restorative justice in Indonesia.

Abstract

A dangerous gas that is harmful to human health and is generally found in the room is carbon dioxide (CO2) gas, which is produced from the accumulation of cigarette smoke. In order to overcome the CO2 gas concentration in the room, it is necessary to develop a device that can control the CO2 gas concentration in the room and that processes the CO2 gas detection results from the MQ-2 sensor. In this research, a device simulation was created that can control the CO2 gas concentration produced by accumulated cigarette smoke in a simulation room measuring 15 cm long, 20 cm wide, and 15 cm high with two CO2 gas release ventilation holes, each with a diameter of 3.5 cm, using the exhaust fan rotation and a microcontroller type Arduino UNO as the control unit. The effectiveness of using a microcontroller of the type Arduino UNO to process the CO2 gas detection results from the MQ-2 sensor can be seen in how the exhaust fan works to release CO2 gas from the simulation room. From the results of this research, it can be seen that the effectiveness of the exhaust fan rotation in controlling the CO2 gas concentration detected by the MQ-2 sensor looks good where the CO2 gas concentration can be controlled under 350 ppm.

Abstract

IPTV merupakan protokol aplikasi TCP/IP yang menggunakan pengalamatan internet (IP Address) dalam suatu jaringan telekomunikasi untuk pengiriman konten multimedia berbentuk audio video, yaitu berupa layanan siaran televisi digital. Dalam perkembangannya, IPTV tidak hanya digunakan untuk mentransmisikan konten siaran televisi dari perusahaan siaran televisi (TV Broadcasting) yang sudah mapan, tetapi juga dapat digunakan untuk mentransmisikan konten siaran televisi lokal (Local IPTV) dalam cakupan terbatas. Agar dapat memberikan kenyamanan bagi pengguna Local IPTV, perlu adanya jaminan kualitas layanan (Quality of Service = QoS) yang dapat diukur dan dianalisa dari kemampuan jaringan lokal dalam mentransmisikan sinyal audio video dengan baik. Oleh karena itu, dalam penelitian ini akan diukur dan dianalisa parameter QoS Local IPTV dalam jaringan IEEE 802.11 (LAN Nirkabel), yaitu perbandingan jarak terminal client ke Access Point terhadap kecepatan data (bit rate), lama waktu memulai siaran (initial time), latency dan kualitas gambar. Metodologi penelitian yang digunakan adalah dengan membuat jaringan sederhana IEEE 802.11 (WLAN) dimana terdapat satu komputer sebagai Server Televisi yang terhubung secara nirkabel dengan dua smartphone, dua notebook dan dua tablet sebagai terminal client; membangun Server Televisi dengan men-setting VLC Media Player; menguji coba dan mengukur kecepatan data (bit rate), lama waktu memulai siaran (initial time), latency dan kualitas gambar pada unit penerima; serta kemudian menganalisa hasil pengukuran. Dari hasil penelitian ini menunjukkan bahwa perubahan kecepatan data (bit rate) dan jarak dapat mempengaruhi lama waktu munculnya file video streaming di terminal client (initial time), latency dan kualitas gambar, serta menunjukkan bahwa penurunan bit rate dapat membuat lama waktu munculnya file video streaming di terminal client (initial time) semakin lama sedangkan besarnya latency dapat dianggap stabil.

Abstract

Electric switches are vital components in railway signaling systems, responsible for directing train tracks. At Jakartakota Station, single electric switches are prone to disturbances caused by high reverse voltage, which can blow 4 A fuses and halt operations. Based on this issue, this study analyzes the effect of using a 10 Ohm 100Watt resistor as a reverse voltage suppression solution. The title was chosen to reflect the specific component specifications, the type of switch system studied, and the precise research location, ensuring a clear research focus. The methodology included measuring current and voltage before and after resistor installation, analyzing system performance under both normal and obstructed conditions, and evaluating effectiveness without major modifications to indoor systems. The results show that installing the resistor reduced detection current from 4.1 A to 1.9 A, preventing fuse failures. Detection voltage remained within the relay’s operating range, while power voltage was unaffected. Compared to previous studies, the novelty of this research lies in its direct testing within an active operational environment, the use of resistor specifications tailored for high-current loads and outdoor conditions, and a practical approach that can be implemented without overhauling the entire system design. Thus, the use of a 10 Ohm 100Watt resistor is proven effective in enhancing the stability and reliability of electric switch systems, extending component lifespan, and supporting operational safety in Indonesia’s railway sector.

Abstract

The public needs to know about safe and healthy use of the internet so that it can prevent harm to the public when accessing the internet. The public needs to be educated about security threats when using the internet, which are generally caused by viruses and phishing on the telecommunications devices they use, such as smartphones, tablets, or computers. Viruses are programs that can spread via the internet to damage the systems of the telecommunications equipment used. Meanwhile, phishing is a fake link in the name of an agency or organization to direct victims to a fake login page as a trap to steal personal data. Therefore, to educate the public about safe and healthy use of the internet, community outreach was held in Batulayang Village, Bogor. The material focused on recognizing the threat of viruses and phishing on the internet. By carrying out outreach about the threat of viruses and phishing in community service in Batulayang Village, Bogor, it is hoped that the community will better understand and be aware of the threat of viruses and phishing so that people in Batulayang Village, Bogor, will be more concerned and alert when using the internet.
