Abstract

The Micro Hydro Power Plant of Gunung Halu was established in 2007. While electricity from the national power grid is available in the village of Gunung Halu, not all hamlets receive a consistent power supply, particularly those with hilly topography and areas surrounded by forests like Dusun Tangsijaya. The existence of the micro hydro power plant in Tangsijaya is supported by a stable water flow from the river. However, one of the challenges faced by the operator is the lack of a monitoring system for the micro hydro power generator that can provide information about its condition, such as power output and electric current. Until now, the operator has checked the data by visiting the location of the micro hydro power plant directly, which is located outside the residential area. Manual recording relies on the existence of human resources and produces results with a low level of accuracy. In this community service activity, a monitoring system was installed at the Tangsijaya's micro hydro power plant. Leveraging Internet of Things (IoT) technology, this system can display data in real time, so that data visualization can be monitored by relevant parties. With a monitoring system, micro-hydro operators can control the usage and distribution of the generated electricity. In addition to obtaining records of daily electricity usage data, recorded data provide very valuable information in assessing current and potential electricity usage for making decisions related to electricity production. After the implementation of the monitoring system, the main benefits are felt by microhydro operators where the work processes they do become more efficient. Efficiency is obtained in terms of travel distance where operators do not need to visit the PLTMH location directly, and also efficiency in the recording process which no longer needs to be done manually.

Abstract

Topoppie, an MSME operating in the food and beverage sector in Bogor, Indonesia, faces challenges including low revenue, limited human resources, underutilised production capacity, and limited digital marketing initiatives. This study aims to evaluate and redesign Topoppie’s business model using the Business Model Canvas (BMC) framework, supported by SWOT analysis and financial simulation. Data were collected through interviews, observations, and literature review. Strategies were formulated using the TOWS matrix and further refined using the Value Proposition Canvas to improve alignment with customer needs. The redesigned business model introduces improvements in customer segments, value propositions, and distribution channels. Financial simulations project a 10% annual sales growth, resulting in a Net Present Value (NPV) of IDR 54,374,131 and a payback period of 1.3 years. This redesigned model is expected to enhance business sustainability and serve as a replicable reference for other MSMEs undergoing digital transformation. Keywords: Business Model Canvas, MSME Topoppie, Digital Marketing, Strategic Planning, Business Transformation, Financial Simulation

Abstract

This study presents a System Dynamics model integrating maritime chokepoint risk in the Strait of Hormuz with mineral-fertilizer supply-chain dynamics, applied to PT Pupuk Indonesia. The problem addressed is that Indonesia's compound-NPK production depends on imported sulfur, phosphate, and potassium, leaving it exposed to a disruption of the Strait of Hormuz through which most of its sulfur supply transits. A continuous-time stock-and-flow model of four raw-material subsystems with first-order sourcing delays, a normalized logistic production response, and a downstream agricultural submodule is validated structurally, parametrically, behaviorally, and under extreme conditions, then analyzed across 2,000 Monte Carlo runs. Under a 180-day total blockade, urea remains fully insulated by domestic gas while NPK is drawn to a critical near-miss trough of 64% as the sulfur buffer falls to 21 equivalent days. Blockade duration and sulfur dependency dominate risk, with 20% of scenarios reaching production halt by day 240, while buffers exceeding 180 days preserve output above 97%. A combined strategy of extended strategic buffer and accelerated alternative sourcing sustains output across all scenarios. We quantify working-capital, fiscal-subsidy, and real-option dimensions and propose a Strategic Sulfur Reserve of about 180 days of consumption as the principal policy contribution for strengthening national food-security resilience.
