Abstract

Pak Pon's chicken noodle SME is a business that sells chicken noodles located in Surabaya. This SME operates by selling only one menu item, chicken noodles, with an average of 200 kg of noodles sold per month, and it still purchases its noodle ingredients from suppliers. Therefore, none of the processes in this SME use machines to prepare the ingredients for the chicken noodles. Given this situation, the researcher has an idea to create a tool that can help streamline the production process in this SME with the aim of increasing sales profit. This research uses cost analysis methods to determine the cost of production, followed by the NPV method to assess whether the equipment purchased by the SME is feasible. The results of this research show that there is a comparison between making the ingredients in-house versus purchasing them. The investment in equipment for the SME is considered feasible, as the payback can be achieved in a few months. This study recommends that the SME increase its sales beyond 200 kg per month in order for the project to proceed as planned. Keywords: Cost analysis, Noodle Dough Tool, NPV, Profit

Abstract

  UMKM Banjar Biscuit "Bu Min" in Sumber Nongko Village, Jombang Regency produces traditional snacks made from sticky rice using manual methods, especially at the dough-pounding stage. This manual process causes physical fatigue in workers, affects production efficiency, and threatens product hygiene. With increasing market demand, UMKM faces major challenges in meeting consumer needs. To overcome this problem, an ergonomic dough-pounding tool was designed with dimensions of 140 cm high, 50 cm wide, 50 cm long, and a mortar diameter of 30 cm. This tool successfully reduced the Work Heart Rate (WHR) of workers from 118-149 to 93-124 beats/minute, indicating a significant reduction in cardiovascular load. In addition to increasing production efficiency, this tool maintains product hygiene and reduces the risk of worker injury. From a financial perspective, the cost of making the tool of Rp 5,306,000 has proven to be economical with an IRR of 5.26% per month (51.2% per year), a Profitability Index of 6.04, a positive NPV, and a Payback Period of only 2 months. This innovation helps MSMEs improve the quality and quantity of production while strengthening competitiveness in a competitive market.

Abstract

Hydroponic systems require precise control over nutrient levels and water flow to ensure optimal plant growth. Manual management is still widely used, which often leads to imprecise nutrient delivery, water wastage, and inefficiency. This study aims to develop an intelligent system based on the Internet of Things (IoT) and fuzzy logic to automatically regulate pH and TDS levels in a Nutrient Film Technique (NFT) hydroponic setup. The methodology includes the integration of pH, TDS, ultrasonic, and flow sensors with an ESP32 microcontroller and the Blynk application. Sensor data is processed using fuzzy logic to produce outputs in the form of liquid volume (liters) and pump activation duration (seconds). The system is designed to control pH UP/DOWN and fertilizer pumps are automatically based on the delta and error values of the measured parameters. Implementation results indicate that the system effectively maintains nutrient stability and reduces water and fertilizer wastage. Additionally, it enables real-time remote monitoring via a mobile application. Therefore, this intelligent system offers an efficient and adaptive solution for supporting sustainable hydroponic farming.
