Analysis of water availability of the Singkoyo River for the irrigation needs in the Banggai Regency, Indonesian

Indonesia relies on its food security by expanding the area and productivity of agricultural land. This condition requires water to irrigate existing rice fields, such as in the Singkoyo area. This study aims to determine the study area’s surface water availability (Q80), irrigation needs, and water balance. Some methods are applied, such as Penman-Monteith for the evapotranspiration calculation, and the FJ Mock method for the dependable flow and water need based on the annual cropping plan. The result shows that the Singkoyo River, with a catchment area of 408.55 km2, has an average flow rate for Q80 is 6.24 m3sec-1, whereas the most significant discharge occurs in July 15.48 m3sec-1 and the smallest occurs in November at 2.86 m3sec-1. On the other hand, applying the worst scenario with three times of planting per year with rice, the need for three irrigation areas vary according to the NFR during the plantation phase from 7.20 m3sec-1 at the 3rd planting season in October, and the lowest is 2.0 m3sec-1 at the 2nd planting season in February. The water balance is mostly surplus from December to August, but then deficit during September to November by -1.34 m3 sec-1 on average.

Geologically, Indonesia is located at the confluence of three of the world's main plates, namely the Indo-Australian Plate, the Eurasian Plate, and the Pacific Plate, which often cause disasters, for example drought. Central Lombok Regency is one of the regencies in West Nusa Tenggara, with these two seasons, most often hit by drought disasters, considering that the rainfall in Central Lombok is very small. So that disaster education and preparedness are needed for residents. This article uses qualitative research methods. The results of the study show that climate field schools have an important role in disaster education. Climate field school is a form of education for farmers that is very useful especially in understanding the weather and climate combined with new agricultural techniques that will allow farmers to plant different crops at different times of the year. Meanwhile, for preparedness, it is carried out through several programs in the form of urging and asking farmers to be disciplined in carrying out cropping patterns according to the zoning in which they are located (rice-padi-palawija or padi-palawija-palawija), mapping of land related to cropping patterns, planting rice parity that requires little water, namely the Situpagendit variety, and urges farmers to insure their rice plants, which is Rp. 36.000/ Ha for one planting season at PT. JASINDI. Keywords: Indonesia's geological location, disaster, disaster education.

Soil fertility classification for sugarcane in supply areas of a sugar mill

Objective. To prepare the fertility classification for the sugarcane-cultivated soils in the Pujiltic Sugarcane Mill (PSM) supply area in order to improve decision-making. Design / methodology / approach. The soils were classified according to their fertility (FCC), using a system based on the quantifiable parameters of the upper soil layer and some characteristics of the subsoil directly linked to the growth of sugarcane. Results. Six factors limited the agricultural potential of the PSM soils: alkalinity, water excess or deficit, clay content, erosion, nutritional deficiencies, and low CEC, which alone or in groups act in detriment of soil fertility. Limitations / implications. Solving these problems requires a comprehensive analysis that considers crop type, planting season, and technology availability. Findings / conclusions. The soil fertility classification system enabled the classification of 11 soil subunits of the PSM area.

Adoption of integration systems of rice and cattle in Serdang Bedagai, North Sumatra

The integrated rice and cattle system (SITT) is an innovative technology package to increase agricultural production and encourage zero waste fulfillment. The technology components introduced include new HYV, fertilization, young seedlings, organic fertilizers, Jajar Legowo, IPM, bio urine, and compost. Although it has been implemented at the farmer level, there are insufficient details of its adoption performance; therefore, it is necessary to measure the adoption to evaluate the technology dissemination. This research objective was to analyze the farmers’ adoption level, adoption period, and technology application frequency. The research was conducted in Serdang Bedagai, North Sumatra, in 2018. The respondents were 40 farmers (cooperator and noncooperator), and the respondents’ selection was made purposively. The data obtained were analyzed using qualitative and quantitative descriptive approaches. The results showed that the adoption of technology by cooperator farmers was higher than noncooperator farmers, both from the perspective of each technology component and the level of adoption. The average duration of technology adoption by farmers was 44,0% require more than one planting season, 28,4% require one planting season, and 27,6% require less than one planting season. The frequency of technology application showed that farmers who apply SITT technology more than two planting seasons were 66,0%, exactly two planting seasons were 24,5%, and one planting season was 9,5%. Thus, to increase farmers’ adoption of technology, the technology should be suited to farmers’ preferences and needs, increase profits and ensure that the technology is available in the field. Moreover, providing continuous assistance during the introduction of technology.

The effect of planting season on physical and chemical characteristics of local rice varieties

The season is the time interval with the most frequent weather. The rainy season is the time when it rains a lot, while the dry season is the time when it rains a little. Planting season is one of the factors that affect the quality of the grain, which directly determines the quality of rice. This study aims to determine the effect of the growing season on the physical-chemical characteristics of rice. The sample observed was the Bujang Marantau rice (local variety) which was taken from two seasons (dry season and rainy season) in the same location, which is Nagari Singkarak, X Koto Singkarak District, Solok Regency, West Sumatra Province. The physical characteristics examined were head rice, broken rice, and groats. Chemical characteristics analyzed were amylose content determined by the IRRI method (1971). Meanwhile, water content and ash content were analyzed by the gravimetric method. In addition, fat content was determined by the Soxhlet method with Weibull modification. Furthermore, protein content was determined by the Kjeldahl method. The results showed that the growing season did not affect the ash content, fat content, and carbohydrates of the Bujang Marantau rice, but affected the water, protein, and amylose content. Based on the quality requirements (SNI 6128:2015), Bujang Marantau rice is included in the medium quality class 1.
