Harvesting is one of the major labor intensive works in rice cultivation. Appropriate harvesting machinery is urgently needed to reduce labor and production costs. Production cost of rice becomes high due to labor shortage and high wage rate during harvesting time. Techno-economic performance of Korean self-propelled reaper (KR), China self-propelled reaper (CR) and BRRI reaper (BR) were evaluated in order to identify the field constrains and problems of the reapers at Mithapukur of Rangpur, Bangladesh during Aman season of 2013. The actual field capacities of the KR, CR and BR were found 0.18, 0.17 and 0.15 ha h–1with the corresponding field efficiency of 55, 68 and 56%, respectively. The variation of field capacity among the models was due to turning time losses, weight of the reaper and operator’s skill. The fuel consumption of the reapers was 4.11, 2.61 and 8.39 l ha–1 for KR, CR and BR, respectively. The shattering loss of paddy harvesting was 1.66, 1.50 and 1.45% for KR, CR and BR, respectively. The break-even area of the reapers was 9.15, 7.82 and 8.43 ha yr-1 for KR, CR and BR, respectively. It is evident that the reaper could be used successfully as labor saving and user friendly technology to eliminate post-harvest problems in Bangladesh.J. Bangladesh Agril.

The experiment was conducted to study the performance of Kukje self-propelled rice transplanter and to study the economic feasibility of mechanical transplanting method over manual transplanting method. Each of the transplanting method had three unit plots of sized 20 m x 10 m. The field efficiency and planting efficiency of the transplanter were 83.33% and 95%, respectively. Percent damaged (3.33%) and missing (5.33%) hills were higher in mechanical transplanting method and percent floating (4.33%) hill was higher in case of manual transplanting method. The average labor input in mechanical transplanting was 1.4 man-day/ha where 25 man-day/ha was in case of manual transplanting. The total production costs were 53612 tk/ha and 49304 tk/ha for manual transplanting and mechanical transplanting methods, respectively. Crop established with mechanical transplanting method resulted in higher average grain yield of 6.66 t/ha than manual transplanting method resulted average grain yield of 5.83 t/ha. The net return of manual and mechanical transplanting method were 42310 and 61080 tk/ha, respectively. The benefit cost ratios (BCR) were 2.24 and 1.78 for mechanical transplanting method and manual transplanting method, respectively. Kukje self-propelled rice transplanter should have break-even area coverage more than 10 ha/yr for economic transplanting. The above result showed that the mechanical transplanting method is more economic than the manual transplanting method. DOI: http://dx.doi.org/10.3329/jbau.v12i1.21406 J. Bangladesh Agril.

Bangladesh has an agrarian economy in which paddy is the dominant crop. A significant amount of field losses of paddy occurs every year due to natural calamities and a shortage of time during the harvesting period. During this study, a modification was done on locally developed BAU self-propelled reaper and its performance was compared with manual harvesting system of paddy. Several experiments were conducted in Boro paddy (April–May 2017) and Aman paddy harvesting (November–December 2017) at BAU farm of Bangladesh Agricultural University after necessary modification works in the workshop. An experiment was also conducted on Aman paddy in 2017 at BAU farm for determining manual harvesting cost. The technical and economic performances of the modified BAU self-propelled reaper were determined based on the field experiments. Results reveal that average fuel consumption, effective field capacity and field efficiency were 2.71 L/ha, 0.255 ha/h and 77.27%, respectively for the modified BAU self-propelled reaper and 2.88 L/ha, 0.25 ha/h and 75.76%, respectively for the existing BAU self-propelled reaper. These results indicated that field performances of modified BAU self-propelled reaper were better than that of the existing BAU reaper. Paddy harvesting cost was found 916 Tk/ha for modified BAU self-propelled reaper and 9200 Tk/ha for manual harvesting system. The benefit-cost ratio of the modified BAU self-propelled reaper was 2.18. Considering the technical and economic performances, modified BAU self-propelled reaper was found suitable than the existing BAU reaper.  So, the modified BAU self-propelled reaper may be introduced in Bangladesh in the commercial basis.J.

The ginger (Zingiber officinale) rhizome is harvested manually by different types of spade, fork or bullock drawn plow. These methods consume more time, cause drudgery, losses and low field capacity. Therefore a tractor drawn digger was evaluated for ginger crop. The performance parameters (exposed, cut, bruised and digging efficiency) of the digger were studied at 3 forward speeds and 3 blade angles. The performance of the digger was found satisfactory in respect of digging efficiency of 98.01%, and undug crop of 2.38 % at an average depth of operation of 15.75 cm. The damage was 1.98 per cent which was much low as compared to manual digging of ginger crop (9.73%). The machine takes 7.4 hours to dig one-hectare area of ginger crop with field efficiency of 87.82%.

This paper will discuss about the immaterial costs and production yields at one of the refined sugar factory companies in Makassar, South Sulawesi. The theory is based on the fact that Immaterial is a cost that is almsgiving, meaning costs that are outside of the basic costs of the company in producing production, so this research aims to find out: (1) what is the production cost needed to produce this production, (2) the maximum level of production at company from 2013 to 2017. This type of research is a quantitative study because it uses a questionnaire in the form of values ​​that are processed using the marginal cost approach formula. The results of the analysis show that (1) the maximum level of production costs occurred in 2016 amounting to 6,912 with an Immaterial cost of Rp. 2,481,796,800 and the total production produced is 359,077.3 tons (2) The required workforce with the total production produced is 359,077.3 tones of 180 people including the maximum production point which means that the lowest value is achieved (optimal).
