“…The physical and chemical characteristics of cassava flour as well as its functional properties from different cultivars have been reported by some studies (Iwe et al, 2017;Lagnika et al, 2019;Lu et al, 2020;Hasmadi et al, 2020). This shows that cultivar and growing conditions may affect the physical and chemical characteristics of the flour and subsequent quality of the products (Putri & Perdinan, 2018).…”

Cassava flour is promising to be used as a food ingredient substitute for wheat and rice flour-based food products. It can be also processed at a rural household level to ensure the income of farmers. This study was aimed at identifying the physical and chemical characteristics of cassava roots and the flour produced as well as the economic feasibility of its production at a small scale. The results showed that cassava flour prepared from Sembung, an Indonesian local variety had fairly good quality parameters according to the national quality standards for moisture, starch, and hydrogen cyanide (HCN) contents, while the physical characteristics were sub-optimal. The yield recovery of cassava flour processing was 20.16% or equivalent to 9.67 ton per year assuming the annual production capacity was 48.00 tons of fresh cassava. A home-scale industry of cassava flour can give a net profit of IDR 49,565,888 or about 3,440 USD per year with the revenue cost ratio of 1.52, net profit margin of 34.15%, return of investment of 51.81% and payback period of 1.02 year. Adjusting the harvest time with crop maturity as well as following proper processing methods would improve the flour yield recovery, quality and economic returns.

“…This information is required to calculate the availability of soil water content in the soil, during surplus and deficit conditions. Water balance method has been widely used for calculating domestic water demand in watershed areas (Putri and Perdinan, 2018), identifying root macroscopic parameter (Hupet et al, 2002), analyzing land water balance (Widodo and Dasanto, 2010), as well as analyzing crop water requirements based on their growth phase (Setiobudi and Sembiring, 2009;Sirait et al, 2020). After the calculation, the result is used as the basis for determining the optimum planting time and cropping pattern to achieve maximum potato production.…”

Many mountainous regions in Indonesia have been utilized for potato cultivation. But location for the cultivation is mainly a rainfed agriculture, which greatly depend on the weather condition. Lembah Gumanti in Solok, West Sumatra is a rainfed main potato-growing area, which faced a low productivity during dry season. Therefore, efforts to optimize potato production in rainfed area remains research challenge. This study aims to identify the optimum cropping calendar for potato and other horticultural commodities in Lembah Gumanti for 2018-2021. We used the water balance approach to derive daily water availability at field level. The approach was used to identify the planting time and pattern of potato and other horticultural commodities for 2018-2023 at dekadal (10-day) interval. The results showed that the most suitable planting time and cropping pattern varied annually. In 2018-2019, the cropping calendar was potato (in October 1st 10-day) – shallots (in April 1st 10-day) – chilies (in July 3rd 10-day). For 2020-2021, the best cropping calendar was shallots (in November 3rd 10-day) – potato (in March 3rd 10-day) – shallots (in August 1st 10-day). The findings reveal that water availability determined the cropping calendar of each commodity.

“…River water availability is an important hydrological indicator that influences the dynamics of daily socio-economic activities. In case of Java Island with dense residential areas, the availability of river water is essential because of the highly community dependency to water (Putri and Perdinan, 2018). However, the real condition shows that most of Java's rivers and their wathershed area are in critical condition (e.g.…”

Hydrological investigation for major Java rivers remains research challenge todays, particularly in identification of runoff characteristics situated in monsoonal climate. This study aims to investigate the value of baseflow index for Bengawan Solo river. We employed daily streamflow data for period 1980-2010 to derive baseflow index (BFI) based on the smoothed minima. We utilized different approaches comprising the non-overlapping 3 days (BFI3), 5 days (BFI5), and 7 days (BFI7) of streamflow to compute the index. We found the average BFI3, BFI5, and BFI7 for this study period are 0.67, 0.56, and 0.49, respectively. It revealed that higher number of non-overlapping days would produce lower BFI, which could be an indication of less baseflow contribution to total streamflow. Additionally, our findings show there is an increasing trend of BFI in the last decade that may be associated with decreasing forest cover in the catchment area. Furthermore, the BFI value will provide a valuable information for key leader in water sector in particular during dry season, and further research is needed to integrate this BFI into sustainable water management index.
