Abstract

Patchouli (Pogostemon cablin Benth) is a tropical shrub that produces the most essential oil in Indonesia. Patchouli can produce 200-300 kg of dried leaves per hectare, which can be distilled into 15-20 liters of oil. The purpose of this study was to determineThe effectiveness of cow manure and liquid organic fertilizer of banana peel on the growth of patchouli cuttings and to determine the best dose of POC for patchouli plants. This study used a factorial Randomized Block Design (RAK) with 2 factors including cow manure and banana peel POC with doses of cow manure, namely: S0 (Control/No treatment), S1 (100 gr/polybag), S2 (200 gr/polybag), S3 (300 gr/polybag). Doses of banana peel POC include: P0 (Control/No Treatment), P1 (15 ml/liter of water), P2 (30 ml/liter of water), P3 (45 ml/liter of water). The parameters observed were plant height (cm), number of leaves (blades), leaf length, number of shoots, age of shoot emergence and percentage of plant survival. The results of the study with the administration of cow manure and banana peel POC gave an effect on plant height, number of leaves, leaf length, number of shoots and age of shoot emergence. However, it did not affect the percentage of survival. The best dose of cow manure is found at S1=100 g/polybag, while for banana peel POC it is found at P3= 45 ml/L water/plot

Abstract

This study successfully designed and implemented an IoT-based Maximum Power Point Tracking (MPPT) system using the Perturb and Observe (P&O) algorithm for a 100 Wp polycrystalline solar panel. The research aims to provide an integrated, cost-effective solution for optimizing solar energy extraction in Indonesia's tropical climate. The methods employed include mathematical modeling, system simulation in MATLAB/Simulink, and hardware implementation using an ESP32 microcontroller with sensors for voltage, current, irradiance, and temperature, integrated with the ThingSpeak IoT platform for real-time monitoring. System validation showed high accuracy with a Root Mean Square Error of 0.83 W. The hardware system achieved an average MPPT tracking efficiency of 95.36% with a response time of 2.05 seconds and power oscillation of 3.17%, contributing to a significant 24.8% increase in daily energy yield compared to a non-MPPT system. IoT performance metrics showed a data transmission success rate of 97.08%, average latency of 2.82 seconds, and system uptime of 99.12%. This integrated MPPT-IoT system offers a practical and affordable technological solution, contributing empirical baseline data for tropical conditions and supporting Indonesia's national energy transition and net-zero emission targets through improved data-driven decision-making.

Abstract

This study aims to analyze the effectiveness of community-based disaster mitigation policies in Lembang District, West Bandung Regency, a densely populated hilly area with a high risk of landslides. The method used in this research is descriptive qualitative, with data collection techniques utilizing in-depth interviews, field observations, focus group discussions (FGD), and documentation studies involving the Regional Disaster Management Agency (BPBD), village officials, and local volunteers. The results indicate that the community-based policy effectively increases the social capacity of residents significantly through the establishment of the Disaster Risk Reduction Forum (FPRB). The strengthening of social capital has successfully reduced independent emergency evacuation response times to less than 15 minutes through regular simulations and community-based patrol systems. However, the long-term effectiveness of this policy faces massive structural barriers in the form of uncontrolled conversion of hilly land for commercial tourism, as well as the operational failure of technical early warning systems (EWS) due to the absence of a consistent maintenance budget from the local government. This study concludes that social resilience at the grassroots level will not operate optimally without the integration of strict ecological spatial control and a sustainable operational budgeting commitment from the local government.

Abstract

Population growth and economic activity in Cimahi City have triggered a significant rise in urban waste generation, necessitating an adaptive and inclusive governance strategy. This study aims to analyze waste management policy in Cimahi City through a collaborative synergy approach involving various stakeholders. A descriptive qualitative research method was employed. The findings indicate that the implementation of waste management policy via collaborative synergy has not been optimal, as it remains dominated by a rigid, top-down government authority. This situation has fostered passivity within the private sector and caused fluctuations in public participation, driven by the absence of economic incentive systems and a lack of mutual trust. Structurally, governance is hindered by land constraints, reliance on regional landfills, overlapping regulatory and operational functions, and outdated local regulations. The study concludes that the success of collaboration hinges heavily on leadership commitment and clearly defined roles. The primary recommendation is the need to accelerate the establishment of a Regional Public Service Agency (BLUD) for waste management and to strengthen formal regulations that integrate the penta-helix model.

Abstract

Digital transformation through smart city policies represents a strategic move to enhance public service quality and the efficiency of local government governance. However, implementation often faces challenges regarding the alignment between infrastructure readiness and the bureaucracy's non-technical capacity. This study aims to conduct an in-depth analysis of the Cimahi City Government's readiness to implement digital transformation via smart city policies, focusing on the initiation phase of the "100 Smart Cities" movement. A descriptive qualitative research method was employed. The findings indicate that the Cimahi City Government possesses robust readiness in terms of formal regulations and physical ICT infrastructure, evidenced by the existence of a Smart City Masterplan, an inter-agency fiber-optic network, and a centralized local data center. Nevertheless, significant obstacles were identified regarding cultural dimensions and human resource capabilities; these include persistent sectoral ego among regional government agencies (silo mentality), a proliferation of overlapping applications, resistance from senior officials to shifting away from manual work systems, and stark disparities in employees' digital literacy. The study concludes that digital transformation readiness in Cimahi City remains uneven, necessitating a strategic shift toward a people-and-process-oriented approach—specifically through the implementation of single sign-on systems and structured digital training reforms for civil servants.
