Along the river, many people live. As a result, many people dispose of their household or industrial waste in bodies of water. On the other hand, community groups are concerned about the river's environment. The study will take place along the Ciliwung River. Social capital data includes togetherness, mutual trust, sharing, cooperation, resource mobilization, and the principle of reciprocity. A survey of 30 people who live along the Ciliwung River. The collected data were processed descriptively, and a dynamic system created a model. According to the findings, the community's social capital of the participatory response is high, at 64.17%. 36% is the average level of reciprocity. The percentage of trust is 37%. Aspects of norms (a set of customary or local rules that apply): 58.5% is a high percentage. Aspects of values are 64% high. The statistical testing results in Fcount > Ftable (39.983 > 3,372) show that the percentage composition in each aspect of social capital differs significantly. When the system dynamics model is built with community social capital (citizens, NGOs, and entrepreneurs) and the role of the government, the quality of the river environment can be achieved in 18 years.

Hand soap is essential during the COVID-19 pandemic for cleaning hands that are frequently used for activities such as touching the face, eyes, and nose. Hand soap contains mangrove leaf extract (Rhizophora mucronata L.), which contains a substance that weakens bacteria. This study aimed to determine the quality of hand soap production by performing organoleptic tests, pH tests, viscosity tests, and foam height measurements. The data were analyzed using one-way ANOVA with a significance level of 5%. In an experimental research method, four formulas were used. The results were tested by 15 Muara Gembong residents using an organoleptic test. It demonstrates that there are differences in the effect of different percentages of mangrove leaf extract (Rhizophora mucronata L.) on the quality of hand soap, namely organoleptic tests (texture, smell, color, and aroma) with a p-significance < 0.05 (0.008 < 0.05). SNI standards are met by the quality of hand soap as measured by pH (8.27), thickness (2216.25 cPs), and foam height (78.71 mm). Hand soap containing 0.02% mangrove leaf extract (Rhizophora mucronata L.) has a better organoleptic quality, according to Muara Gembong respondents, with an average score of 4.26.

This study aims to develop a device that uses DC lamps as a notification of a telephone ringing in a noisy room. The research method involves observing the Cikande electronic ambassador shop and proposing the use of a DC lamp as a replacement for the speaker output of the telephone. The device includes a PNP transistor type as an amplifier and multiple LEDs to ensure visibility in a noisy environment. The result is a functional device that uses DC lamps to notify the ringing of a telephone in a noisy room. The implication of this research is that it provides a solution for situations where conventional ringing tones from telephones are not audible due to noise pollution. The device can be useful in various settings, including busy offices, factories, and public spaces.

This study aimed to develop a child supervision tool with a sound system to help parents quickly detect and locate danger to their children. The tool utilizes a Push Button or a microphone that, when activated by the child saying "Danger," sends the GPS coordinates to a NodeMCU ESP8266 microcontroller that sends location signals and notifications to the parent’s smartphone. The buzzer on the device also activates to alert the parent of danger. The study found that Voice Recognition as a sender of Blynk notifications and activating the buzzer function properly, and the GPS U-Blox Neo 6m accurately captured locations with an accuracy rate above 99%, with a sensor reading error rate below 0.1%. The implication is that this tool can help parents supervise their children and prevent them from becoming victims of kidnapping.

A manipulator robot is a robot that has a mechanical system consisting of an arrangement of arms and joints that can produce controlled movements. A robotic arm usually consists of several joints including the base, shoulder, elbow, roll, gripper, and pitch of the gripper. Robot movement is generated from mathematical calculations performed in the controller. The motion of the manipulator robot follows a motion trajectory. The motion trajectory is made based on a collection of stop points and effectors. This study aims to create a robot motion trajectory design system using Lagrange interpolation. Lagrange interpolation is engineered to be embedded in precise microcontroller control systems. In this study, an Arduino Uno R3-based microcontroller was used as a data acquisition module. Prediction of the robotic arm's trajectory has been successfully made using Lagrange interpolation. The rise time is 15 seconds, the delay time is 12 seconds, the steady-state time and the peak time are 21 seconds. While the second experiment increased 9 seconds, 7 seconds of delay, steady-state time, and 13 seconds of peak time. Then for the third experiment, the rise time is 17 seconds, the delay time is 14 seconds, the steady-state time and the peak time are 22 seconds, the overshoot value and the steady-state error value is 0% where the output value produced is by the input value.
