“…This study is a follow-up study conducted by Budiarso et al, [16], and it verifies the study conducted by Gaiser et al, [23]. The Turgo turbine designed by Budiarso et al, [16] exhibits a hydraulic efficiency of 44.3% and an investment cost of USD 48. On the other hand, the turbine designed by Gaiser et al, [23] exhibits a hydraulic efficiency of 63.4% and an investment cost only of USD 30.…”

“…Hence, the boundary conditions proposed by Gaiser et al, [23] are appropriate for use in the design of a pico-scale Turgo turbine. Moreover, the investment cost required to manufacture a Turgo turbine using coconut shell material is USD 29, which is more cost-effective than those reported by Budiarso et al, [16] and Gaiser et al, [23] (see Table 5). This price does not include all of the cost, if the including the DC generator and piping system the total price for manufacture is USD 85.…”

“…On the other hand, the turbine designed by Gaiser et al, [23] exhibits a hydraulic efficiency of 63.4% and an investment cost only of USD 30. However, the reliability of the Turgo turbines designed by Budiarso et al, [16] and Geiser et al, [23] for applications is still doubtful because the reported efficiency is the hydraulic efficiency and not the total efficiency (electrical power). To clarify this doubt, the design of the runner dimension utilizes the boundary conditions proposed by Gaiser et al, [23], with the only difference being the bucket material, and this turbine is connected to the DC generator.…”

“…Based on the assessment by multi-criteria analysis, an impulse-type pico-scale Turgo turbine is recommended for applications in remote areas [15]. Turgo turbines are suitable in remote areas due to their low investment costs, portable, easy to operate and easy maintenance [15,16].…”

“…The use of materials that are widely available in the market as raw materials for the Turgo turbine buckets has been carried out. For example, stainless-steel spoon materials have been used for making Turgo turbine buckets due to their cost-effective [16,23]. Such examples provide new ideas from local Indonesia people for the application of pico hydro.…”

villages in Indonesia, deemed as remote areas, still did not have access to the national grid electricity. To resolve this issue, the use of independent power plants is an appropriate solution. The use of a pico-scale Turgo turbine, which is an independent power plant, is recommended in Indonesia due to its mini-, micro-, and pico-scale water energy potential of 19 GW. As the Turgo turbine is intended for use in remote areas, the use of local materials, e.g., coconut shells, is proposed as the bucket material. From static compressive strength tests revealed that the maximum pressure points a coconut shell proportional to the water pressure with a potential power of 3300 W. The size of a coconut shell spoon, which is not uniform, can be overcome by its curvature angle. The curvature angle represents the relative angle of the incoming and outgoing jets, while this is a represents of the depth and length of the spoon. Thus, to ensure the performance of the Turgo turbine under maximum conditions, the curvature angle of the coconut shell spoon is ~90°. Moreover, the total efficiency of the turbine is 34.94%, with a possibility of reaching higher values.
