Abstract

Tidal lowland is a marginal land characterized by low pH, deficient  nutrients, and salinity. Despite these challenges, El Niño phenomenon often occurs during the second planting season, resulting in long droughts. However, tidal lowland must be used for cultivation due to the need for rice and the land should be treated accurately. Therefore, this research aimed to address the issues by improving the efficiency of rice cultivation on tidal lowland through precision farming practices. A survey and land analysis were conducted in tidal lowland of B typology in Delta Saleh, Indonesia, from March 2023 to June 2023. In this precision farming practice, water management was highly prioritized, starting from tertiary channels such as optimizing sluice gate operations and monitoring water levels in channels and groundwater. Additionally, pH, CEC, and C-Organic analysis were also carried out in rice cultivation, as showed by the  equation Y = 0.15 - 0.001 pH + 0.000 CEC + 0.000 C-Organic. The highest production yield was 2.05 tons/ha in P5, with the SEW-10 value during cultivation activities being 778 cm and the number of days above -10 reaching 84. Moreover, the efficiency of rice cultivation was improved through precision agricultural practices by using valve sluices and levees.

Abstract

Tidal lowland productivity in type C is still low. Most of them have only been able to cultivate rice twice a year. The third cultivation of corn often fails due to a lack of water. The research objective is to determine an operational model for water management in the field for maize cultivation at several planting times. Model area is conducted at a tertiary block of reclaimed tidal lowland, Telang Jaya Village Primer 8 Delta Telang I, of  Banyuasin District. There are three planting times treatments: the fourth week of April, the second week of June, and the first week of July, 2021. A water management model was applied to control the drainage system, in which the water level in the tertiary channel is maintained at a depth of 50 cm. When groundwater drops below 70 cm, and there is no rain, pump irrigation is provided. Results of the field experiment showed that the maize crop showed similar growth quality at each phase. Land with a planting period of June and July still requires water addition using pump irrigation. It was applied on 14th and 18th August. Moreover, the maize cultivated at the end of April did not require pump irrigation. All treatments have generally similar production with an average magnitude of 8.0 Mg ha-1. The highest production is 8.73 Mg ha-1, which is planted in the first week of July.

Abstract

The agriculture sector in Indonesia contributes 14.5% share of gross domestic product (GDP) in 2012 and the number of farmer accounts for about 40% of total labor force population in Indonesia. However, many of the irrigation systems have seriously been deteriorated. Consequently, DGWR (Director General of Water Resources) cannot operate the irrigation systems properly and the farmers have been facing difficulties in obtaining sufficient irrigation water and rice production. Based on the results of “appraisal mission for Rentang Irrigation Modernization Project between Japan  International Cooperation Agency (JICA) and Government of Indonesia Represented by Ministry of Public Works and Housing and National Development Planning Agency” (August 2016), the Rentang Irrigation Modernization Project (hereinafter called RIMP) was started in August 2020. The RIMP consists of 15 packages for canal upgrading works, one (1) package for TM/TC system works, and one (1) package for Modernization Support Program (hereinafter called MSP). This paper mentions the land consolidation which is one of important and advanced activities in the RIMP, including background of the first introduction in Indonesia, site selection, socialization with benefit farmers, survey including geographical and cadastral and agricultural soil, design of irrigation canals and drains and farm roads, a land reallocation plan, issue of land certifications, improvement of soil, coordination with farmers during construction, introduction of IPHA (Water Efficient Rice Irrigation) and mechanization, and a knowledge movie. The implementation resulted in about a 90% increase in plot size and notable improvement in irrigation efficiency.
