Public street lighting, also known as street lighting, refers to the outdoor lighting systems used to illuminate public roads. An effective street lighting system plays a crucial role in enhancing safety and security for pedestrians, cyclists, and motorists by providing improved visibility of the road and surrounding terrain during nighttime hours.  The primary focus in street lighting planning is on economic factors. An analysis of light sources has highlighted the economic advantages of utilizing light emitting diodes for public street lighting. This choice proves to be more efficient when implemented in a sustainable manner. The installation of public street lighting can be the optimal solution to address the issue of inadequate lighting in the village of Pedurenan Gunung Sindur Bogor, ensuring enhanced comfort and security during nighttime activities. The lighting installation process commences with a thorough examination of the site, followed by diligently arranging and design of the electrical installations for the lighting system. Finally, the planned design was carried out and implemented. The implementation of public street lighting is a collaborative effort between college students and youth residents in the village. The outcome of this community service initiative is the implementation of public street lighting installations that offer optimal illumination, ensuring the convenience and safety for all people accessing the roads.

Technology has the potential to be employed within the realm of electronics and informatics, particularly for the purpose of securing household doors using a smartphone through an internet connection. The Internet of Things (IoT) embodies a concept where internet-enabled devices can communicate with each other and their surrounding objects. This endeavor seeks to create a prototype using key components, including NodeMCU Esp8266, Servo Motor, and Fingerprint Module, with the ultimate goal of simplifying daily tasks and alleviating concerns about leaving the door unlocked upon leaving the house. The mechanism of this device entails utilizing a smartphone app to establish an internet connection, enabling users to seamlessly close and lock their house door. The underlying intention behind developing this tool is to provide assistance in managing both indoor and outdoor activities, addressing the issue of inadvertently leaving the door unlocked, and substituting traditional door locks with fingerprint recognition. By employing this innovation, individuals can conveniently regulate their house door via smartphone, saving time and effort and seamlessly integrating it into their daily routines.

Historically, the outer space structure of the Sentani traditional defense settlement is an ancestral formation aimed at protecting its citizens from outside intervention and defending themselves from tribal wars. The phenomenon of this ancestral formation is maintained until now as a pattern of traditional Sentani defense settlements. From the previous research has been stated, research on traditional settlement patterns on the meaning of defense and the sacredness of outer spatial planning has never been carried out. No research reveals that the sacred outer space in the traditional Sentani settlement is a phenomenon formed by a sacred defense space to protect indigenous peoples from intervention and tribal wars. The research method used is a qualitative approach using the Intrisic Case Study Approach model with the nature of descriptive research. Data analysis in this study used the method of Discovering Cultural Themes. The locus of this research is the oldest village written in historical references and the Sentani traditional village on Lake Sentani today. The data collection method used observation, in-depth participant interviews, measurable pictures, and photographs. The study results found that the structure of the sacred outer space of the traditional settlements formed by the ancestors is still maintained today as a pattern of traditional Sentani defense settlements. The structural pattern of the sacred space forms a defense space in the traditional Sentani settlement forming a sacred outdoor layout for the Sentani indigenous people with one entrance for visitors or guests to the traditional village, namely a wooden pier for the boat landing. The sacred outer spatial arrangement is indicated by the position of the "Obe Imae" traditional house as the center of activity and customary activities are located at the very front, the two customary zones as the seat of tribal chiefs (traditional devices), the third community zone as the residential space of indigenous peoples, the fourth zone ancestors (traditional graves) and the fifth highest worship zone, namely the church as a place of worship to God.

The occurrence of the '19 covid pandemic requires people to reduce activities, and even stop outdoor activities as an effort from policies carried out by the government to stop the spread of '19 covid. But of course, this policy makes people confused, especially people who have jobs that require them to leave the house and do outdoor activities. Not only that, the country's unstable economic condition also makes many companies in Indonesia decide to terminate their cooperation with employees unilaterally to maintain the financial stability of their companies. Therefore, during the pandemic, so much new unemployment was caused by layoffs. But because of this, many people have lost their jobs and those who lack the ability and skills in a field of work are forced to enter a job, or maybe it cannot also be called a job, namely begging, and one form of beggar today is street clowns. This research will focus on the figure of street clowns at the Mastrip Roundabout Red Light, as well as the background that makes them eventually become street clowns. This research is a research that uses qualitative methods with a phenomenological approach, and the theoretical basis used is the theory of Social Action proposed by Max Weber. Data collection using observation, interviews, and documentation.
