Abstract

Abstrak Kelompok tani Sedyo Maju Bumiharjo, Kemalang, Klaten mendapat bantuan dari pemerintah yaitu mesin chopper atau mesin pencacah rumput yang saat ini sudah tidak digunakan karena penggerak mesin yang digunakan sulit dinyalakan, mata pisau yang sudah tidak tajam dan kapasitas yang rendah yaitu 50 kg/jam dan bahan bakar diesel yang boros yaitu dua liter per jam sehingga belum ideal untuk kegiatan peternakan di Sedyo Maju sehingga mesin ini tidak digunakan. Selain alasan tersebut penelitian ini dimaksudkan agar tercipta design mesin chopper yang optimal. Dalam memecahkan masalah tersebut, dilakukanlah uji kelayakan / usability menggunakan metode USE Questionnaire dengan menugaskan 32 responden melakukan uji coba mesin chopper dan memberikan kuisioner terhadap lima parameter, hasil kuisioner kemudian di tes dengan uji validitas dan reliabilitas sehingga didapat nilai learnability 83,4%, efficiency 65,9%, memorability 85,6%, errors 86,5%, dan satisfaction 73,4%, dan rata-rata parameter 78,96% karena nilai efficiency merupakan parameter yang terendah, maka di indikasikan bahwa mesin tidak optimal dalam memproses tenaga dan waktu secara ringkas, atas dasar tersebut dilakukanlah perbaikan mengganti penggerak dengan dynamo listrik, menambah corong input menjadi dua, dan mengganti mata pisau menjadi baja. Langkah selanjutnnya mengukur usability mesin chopper usulan dengan cara pemerolehan data yang sama sehingga didapat nilai learnability 88,4%, efficiency 77,5%, memorability 89%, errors 88,4%, dan satisfaction 85,9% dan rata-rata dari semua parameter 85,84%, sehingga mesin disimpulkan layak. Kata Kunci: Mesin chopper, usability, USE Questionnaire, validitas, reliabilitas. ABSTRACT The farmer group, Sedyo Maju Bumiharjo, located in Kemalang, Klaten, has received government assistance in a chopper machine or grass chopping machine. However, this machine is currently not being used due to several reasons. Firstly, the engine used is difficult to start, making it inconvenient for the farmers. Secondly, the blades of the machine have become dull over time, reducing its effectiveness. Additionally, the machine has a low capacity of only 50 kg/hour, which is not sufficient for the livestock activities in Sedyo Maju. Moreover, the machine consumes a wasteful amount of Diesel fuel, approximately two liters per hour. Considering these factors, the machine is not suitable for the intended purpose and has been left unused. In order to address this issue, a research study was conducted to develop an optimal chopper engine design. A USE Questionnaire method was employed to evaluate the feasibility and usability of the machine. A total of 32 respondents were assigned to test the chopper machine and provide feedback through a questionnaire based on five parameters. The results of the questionnaire were then subjected to validity and reliability tests. The learnability value was found to be 83.4%, efficiency 65.9%, memorability 85.6%, errors 86.5%, and satisfaction 73.4%. The average parameter value was calculated to be 78.96%. Notably, the efficiency parameter had the lowest value, indicating that the machine was not optimal in its processing capabilities. Based on these findings, several improvements were implemented. Firstly, the drive of the machine was replaced with an electric dynamo, which would facilitate easier starting. Secondly, the input funnel was increased to two, allowing for a higher capacity. Lastly, the blade of the machine was changed to steel, ensuring sharper and more efficient cutting. These modifications were made with the aim of enhancing the performance and usability of the chopper machine. The next step is to measure the usability of the proposed chopper machine by obtaining the same data to obtain a learnability value of 88.4%, efficiency of 77.5%, memorability of 89%, errors of 88.4%, and satisfaction of 85.9% and the average of all parameters 85.84%, so the machine is concluded to be feasible. Keywords: Chopper machine, usability, USE Questionnaire, validity, reliability.
