Abstract

Abstrak. Akurasi dalam sistem pengisian cairan merupakan aspek krusial dalam berbagai industri seperti minuman dan farmasi. Penelitian ini bertujuan untuk membandingkan akurasi sensor flowmeter YF-S401 dan sensor load cell HX711 pada sistem pengisian botol berbasis mikrokontroler ESP32. Sistem dirancang untuk membaca volume cairan menggunakan dua metode, yaitu berbasis aliran dan berbasis berat, yang ditampilkan secara real-time pada LCD I2C. Pengujian dilakukan pada dua target volume, yaitu 500 mL dan 1000 mL, masing-masing sebanyak lima kali. Hasil menunjukkan bahwa sensor load cell memiliki akurasi lebih tinggi, dengan rata-rata error sebesar 2,92% pada 500 mL dan 1,85% pada 1000 mL. Sementara itu, sensor flowmeter mencatat error sebesar 35,49% dan 22,26%. Dengan demikian, sensor load cell lebih direkomendasikan untuk aplikasi pengisian cairan dengan kebutuhan akurasi tinggi, khususnya pada volume kecil.

Abstract

This research is based on the theory of farm household economics developed by Nakajima, modified by incorporating Miller’s concept of household investment. The aim of this study is to determine whether the Nucleus Estate Smallholder (PIR) Project has succeeded in developing farmers’ ability to invest at the household level. The research was conducted in the Sungai Bahar area, involving 100 independent smallholder respondents from the former oil palm PIR project. The collected data were processed descriptively. The findings show that during the middle period up to about two-thirds of the planting cycle, oil palm cultivation with a land area of 2 hectares still generates a surplus between revenue and costs, enabling farmers to make investments. However, after passing that period—entering the final stage of the planting cycle—there is an indication that 2-hectare oil palm farmers are no longer able to set aside income for replanting or other investments. Independent oil palm smallholders from the ex-PIR project who have successfully made investments are proven to be more resilient in maintaining oil palm plantations that have not yet been replanted, due to the availability of alternative sources of income. The findings of this study suggest that in the last phase of the planting cycle, when production decreases and maintenance expenses remain high, smallholder farmers do not have enough cash to replant. This highlights the need for state support (subsidies, soft loans, and revitalization initiatives) to keep smallholder farmers from becoming locked in a cycle of old, unproductive plantations. Furthermore, farmer empowerment programs should include household economic diversification, not simply palm oil output.
