Mesin pengiris singkong dengan sistem crankshaft ini dirancang bertujuan untuk mempermudah meningkatkan nilai tambah dan efisiensi dari sebuah proses pembuatan singkong terhadap hasil irisan singkong. Mesin ini digunakan untuk membantu para petani kecil untuk menghasilkan produk yang besar, hemat waktu dan tenaga kerja. Pada dasarnya prinsip kerja mesin pengiris singkong ini berawal dari sebuah motor listrik yang menghasilkan daya dan putaran yang ditransmisikan ke poros. Dalam prosesnya kami mengalami masalah mengenai variasi hasil kualitas dan kuantitas dari mesin pengupas ini yang bertujuan untuk meningkatkan performa mesin. Untuk dapat mengatasi variasi hasil tersebut dapat dilakukan pengujian dalam tiga kali pengujian dengan 1 kg tiap pengujian dengan 3 variasi diameter puli yaitu 115 mm (6 inch), 87 mm (3 inch) dan 79 mm (3,425 inch). Hasil pengujian dengan menggunakan daya motor listrik sebesar 0,5 HP dan efisiensi tertinggi didapat sebesar 18 detik.

“…In recent years, multi-objective optimization methods have demonstrated significant advantages in addressing the optimization problems of cascading hydroelectric power stations. Research in references [12][13][14][15] indicates that these methods employ multiple objective functions to comprehensively consider performance indicators from various aspects, providing a more comprehensive perspective for decision making. This comprehensive performance assessment helps decision makers gain a comprehensive understanding of the trade-offs and compromises between various factors, enabling the formulation of more effective optimization strategies.…”

There exists a temporal and spatial coupling effect among the hydropower units in cascade hydropower stations which constitutes a complex planning problem. Researching the multi-objective optimization scheduling of cascade hydropower stations under various spatiotemporal inflow impacts is of significant importance. Previous studies have typically only focused on the economic dispatch issues of cascade hydropower stations, with little attention given to their coupling mechanism models and the uncertainty impacts of inflows. Firstly, this paper establishes a coupled optimization scheduling model for cascade hydropower stations and elaborates on the operational mechanism of cascade hydropower stations. Secondly, according to the needs of actual scenarios, two types of optimization objectives are set, considering both the supply adequacy and peak-shaving capacity as indicators, with the total residual load and the peak-valley difference of the residual load as comprehensive optimization objectives. Subsequently, considering the uncertainty impact of the inflow side, a stochastic optimization model for inflow is established based on a normal distribution probability. Finally, case study analyses demonstrate that the proposed model not only effectively achieves supply stability but also reduces the peak-valley difference in load, and can achieve optimized scheduling under the uncertain environment of inflow.
