Abstract

Swamp land is a natural resource that can be utilized to improve community welfare, because swamp land is one of the potential natural resources and can be used as agricultural land development. The aim of this research is to analyze the tidal water movement patterns of rivers and channels in the swamp irrigation area of Palingkau. The stages in this research included the installation of an Automatic Water Level Recorder (AWLR) to collect real-time water level data, then modeling the tidal movement of river water level using HEC–RAS modeling. The results of this research showed that the pattern of tidal water flow movement in the swamp irrigation area of Palingkau is diurnal tide, characterized by the existence of one high tide and one low tide in one day. Furthermore, HEC–RAS modeling can be used to describe the tide of water levels in the swamp irrigation area of Palingkau. Validation of the HEC–RAS model shows that the tidal flow modeling simulation is good and very suitable for use. Based on the hydrotopography class, the land at the research location is classified into 3 classes, namely hydrotopography classes of B, C, and D. Keywords: Agriculture, HEC–RAS Modeling, Hydrotopography, Land, Swamp.

Abstract

Farmers play an essential role in producing food and meeting the community's food needs. However, they often face various obstacles and challenges in efforts to increase crop yields to boost agricultural income. One approach to increasing agricultural productivity is by understanding the Efficiency and Profitability of Rice Farming with the transplanting system (TAPIN) and the direct seeding system (TABELA) in Padang Mentoyo Village, Kapas District, Bojonegoro Regency. This study used the Data Envelopment Analysis (DEA) method, with 74 respondents consisting of 37 TAPIN farmers and 37 TABELA farmers, to determine the level of efficiency and profitability between TAPIN and TABELA. The results showed that TABELA farmers are more efficient than TAPIN farmers because as many as 97.3% of TABELA farmers are included in the High and Full Efficient categories. This is because implementing the TABELA system is able to reduce the time needed to move seedlings, so that the planting process is faster. Keywords: Direct seeding system (TABELA), Transplanting system (TAPIN), Rice farming income, Yield.
