Abstract

This study aims to determine the level of farmers' perceptions of Alsintan Service Enterprises (UPJA) and the factors that influence farmers' perceptions of UPJA. The research was conducted using survey techniques, descriptive analysis and inferential statistics. The research location was determined purposively, namely Gunungkidul Regency, Yogyakarta Special Region. The UPJA sample was determined purposively, namely UPJA Tirtosari. The sample of farmers was determined purposively, namely UPJA customer farmers as many as 30 respondents, both members of the UPJA group and not members of the UPJA group. Analysis of the level of farmers' perceptions of UPJA statistically quantitative descriptive using a Likert scale with a score of 1 - 5, and the factors that influence farmers' perceptions using multiple linear regression analysis with the Ordinary Least Square (OLS) method. The results showed that farmers' perceptions of UPJA with a score of 4.31 were in the very good category. Perception-forming factors, namely length of formal education, age, farming experience, land area, access to information, the role of extension workers and the role of farmer groups simultaneously influence farmers' perceptions of UPJA significantly. The factor of the role of farmer groups influences farmers' perceptions of UPJA very significantly.

Abstract

Meningkatnya permintaan pangan di Indonesia menuntut peningkatan efisiensi dalam proses pertanian, khususnya dalam penanganan pasca panen. Salah satu solusi yang dapat diterapkan adalah penggunaan alat mekanis seperti grain handler berbasis sistem screw conveyor. Tugas akhir ini bertujuan untuk merancang grain handler berbasis screw khusus untuk gabah, jagung dan kedelei menggunakan perangkat lunak SolidWorks serta melakukan simulasi struktural pada desain rangka. Proses yang dilakukan meliputi studi literatur, pengukuran, pembuatan sketsa, pemodelan 3D bagian, perakitan, dan simulasi pembebanan. Hasil simulasi menunjukkan tegangan maksimum sebesar 55,69 MPa, perpindahan maksimum sebesar 1,147 mm, dan factor of safety (FOS) minimum sebesar 6,374, yang mengindikasikan bahwa struktur tersebut cukup aman. Proyek ini menghasilkan desain grain handler yang dapat dijadikan referensi untuk pengembangan alat pascapanen di sektor pertanian.
