Abstract

Walking Rice Transplanter merupakan salah satu alat dan mesin pertanian (alsin) pengembangan mekanisasi pertanian. Alsin ini banyak terdapat di Kabupaten Tangerang, tetapi pemanfaatan alat tersebut masih sangat rendah karena petani masih menggunakan tanam padi dengan sistem konvensional yaitu tandur (tanam mundur). Penelitian ini bertujuan untuk mengidentifikasi dan mengetahui kapasitas kerja lapang dan teoritis alsin tanam, serta efisiensi lapang alsin tersebut. Metode yang digunakan dalam penelitian ini adalah eksperimental lapangan dan analisis deskriptif menggunakan alsin tanam padi walking rice transplanter 4 baris dengan sistem tanam jarwo 2 : 1. Penelitian ini dilakukan dengan 4 lahan di BPP Sepatan, Kabupaten Tangerang, Banten dengan data yang diperoleh adalah luas lahan, lebar kerja, kecepatan, waktu, jumlah dapog (tray) dan konsumsi BBM. Hasil penelitian ini menunjukkan bahwa kecepatan 2,3 km/jam dapat menghasilkan kapasitas lapang teoritis (KLT) adalah 0,120 ha/jam atau setara 8,32 jam/ha, sedangkan kapasitas lapang efektif (KLE) diperoleh 0,123 ha/jam atau 8,04 jam/ha dengan efisiensi lapang sebesar 96,5%. Hasil ini dipengaruhi oleh 3 (tiga) faktor yaitu luas lahan, kondisi lahan dan keterampilan operator.

Abstract

Harvesting of cassava is still mostly done manually by pulling cassava stems that are ready to be harvested. This study aimed to determine the amount of force required to pull cassava stems. The research was conducted on farmer's land in Bandar Agung Village, Bandar Sakti District, Central Lampung Regency. A sample of 50 cassava trees was selected to represent the center and four edges of 1-ha area sizing of 50-m x 200-m. Measurement of the pulling force of cassava was carried out using a winch supported by a triangular frame of iron pipe and equipped with a 100-kg chicken scale and rope. Parameters included force to uproot cassava stem, soil moisture content, soil hardness, stem circumference, plant height, and cassava tuber weight. The results showed that the uprooting force of cassava stem ranged from 20 kg (196 N) to 70 kg (686 N) with an average of 44.9 kg (440.2 N). The results also showed that the pulling force of cassava decreased with increasing soil moisture content with a range between 196 kN at soil moisture 15,9% and 686 kN at soil moisture 10%. Factors of plant height, stem circumference, and tuber weight also had a positive effect on the pulling force of cassava.

Abstract

Mini combine harvester is a modern machine used for cutting rice, threshing and cleaning grain while walking in the field. This machine helps farmers where, time and energy to harvest more efficiently and does not require a large amount of labor like traditional (manual) harvesting. This study aimed to calculate and determine the working capacity of the mini combine harvester machine and calculated the work efficiency of the mini combine harvester machine. The method used in this research was experimental using a mini combine harvester type Yanmar model YH150 with Ciherang 32 rice varieties ready to harvest. The results of this study indicated that the effective field capacity is 0.125 ha/hour or 8.028 hour/ha, while the theoretical field capacity was 0.234 ha/hour so that the field efficiency is 53.23%. Keywords: field efficiency, field capacity, rice, mini combine harvester
