چکیده

هدف از این پژوهش، بررسی میزان ضایعات حاصل از برداشت نیشکر در شرکت کشت و صنعت نیشکر امام خمینی (ره) واقع در منطقه شعیبیه بود. برای الویت‌بندی عوامل مؤثر بر میزان ضایعات از فرآیند تحلیل سلسله مراتبی استفاده شد. نتایج آماری حاصل از اندازه‌گیری ضایعات نشان می‌دهد که بین سن مزرعه و میزان ضایعات حاصل از برداشت نیشکر رابطه مستقیمی وجود دارد. این رابطه با دقت یک درصد بررسی شده است. همچنین با استفاده از اطلاعات ثبت شده، چهار معیار مؤثر به همراه 23 زیرمعیار در نظر گرفته شد. برای تعیین وزن معیارها و زیرمعیارها، پرسشنامه‌هایی بر مبنای مقایسه‌های زوجی تهیه و توسط مسئولین کشت و صنعت تکمیل گردید. با توجه به وزن‌ به‌دست آمده در معیارها، کمبود نیروی انسانی متخصص و ماهر (مهارت اپراتور) (426/0)، عدم مدیریت صحیح مزرعه (368/0)، عدم مدیریت صحیح برداشت محصول (229/0)، تنظیم نبودن دستگاه‌های برداشت و عدم مدیریت صحیح فنی (076/0)؛ به‌ترتیب رتبه‌بندی شدند. کنترل و هدایت نادرست سبد حمل نی (194/0)، فقدان آموزش کافی برای اپراتورها (176/0) و عدم قرار گرفتن محصول (استقرار گیاه) روی سطح کشت (148/0)، سه زیرمعیار مهم با توجه به بیشترین وزن به‌دست آمده می‌باشند. به‌دنبال محاسبه میزان ضایعات حاصل از برداشت نیشکر به برآورد درآمد حاصل از ضایعات پرداخته شد. این مورد برای تمام مزرعه‌های مورد بررسی در این مطالعه محاسبه گردید و نتایج اقتصادی نشان داد میانگین درآمد حاصل از ضایعات نیشکر معادل 70/123 دلار به ازای هر هکتار می‌باشد.

چکیده [English]

The aim of this study was to investigate the amount of sugarcane losses during harvesting at the Imam Khomeini Sugarcane Agro-Industrial Company located in the Shoaibiyeh region.  Analytical hierarchy process was used to prioritize the factors affecting the level of losses. The statistical results obtained from measuring the losses showed a direct relationship between the age of the farm and the amount of sugarcane losses during harvesting. This relationship was examined with an accuracy of one percent. Additionally, using the recorded information, four effective criteria along with 23 sub-criteria were considered. Questionnaires based on pairwise comparisons were prepared and completed by agriculture and industry officials to determine the weights of the criteria and sub-criteria. Based on the obtained weights of the criteria, the lack of skilled and expert human resources (operator skills) (0.426), improper farm management (0.368), improper crop harvesting management (0.229), and the lack of adjustment of harvesting machines and improper technical management (0.076) were ranked in order. Improper control and management of the sugarcane transportation basket (0.194), insufficient training for operators (0.176), and the lack of placement of the product (plant deployment) on the cultivation surface (0.148) were the three most important sub-criteria based on their highest weights. After calculating the amount of sugarcane losses, the revenue obtained from the losses was estimated. This was calculated for all the farms studied in this research, and the economic results showed that the average income obtained from sugarcane losses was equivalent to 123.70 $ ha-1.
