Rice is still a strategic commodity in Indonesia. The need for rice to fulfill staple food every year tends to increase in line with the rate of population growth in Indonesia Lampung Province government continues to strive for various programs to fulfill food. One of the efforts made is optimizing the use of marginal land in the swampland. The swampland area in Lampung is about 162,930 ha, consisting of 68,900 ha of tidal swampland and 94,030 ha of lowland swamps. Lampung potential swampland, has the opportunity to meet food needs, especially rice. Problems of swampland rice farming which commonly found are environmental stress related to water and land management, unadaptive rice commodities and applying appropriate cultivation technology. Swampland rice farming is expected to provide added value and benefits for farmers. This study aims to analyze rice farming in the tidal swampland of Tulang Bawang Regency, Lampung Province. The farm study was carried out by planting rice on a 1 ha tidal swampland. The rice planted is the existing local rice varieties. The study was carried out in the second planting season. The results of the study showed that the growth and production of rice is quite good. Rice farming in the tidal wetland provides an advantage over an R/C ratio of 1.46 and an R/C ratio of 1.72. So that rice farming in the tidal swampland is feasible.
This study aims to spatially analyze the suitability and availability of land for annual tropical fruit horticultural commodities using the criterion-weighted method. The highlands of Banjarnegara and Wonosobo Regencies, Central Java Province, Indonesia, with a total area of 93,955.60 hectares was used as the study area. The multi-criteria decision-making analysis with an analytical hierarchy process (AHP) structure was used to determine the important criteria for complex land suitability. The criteria consisted of soil great groups, elevation, land slope, rainfall, temperature, humidity, type of land use, distance to market, and road access. Meanwhile, the weight of the importance of each criterion was based on the opinions of seven experts and the results were integrated as the basis for map overlays using ArcGIS ver 10.8. The calculation of pairwise comparisons showed that the soil great groups have the highest weight in determining land suitability, with the majority of land being hapludands. Furthermore, it also showed that 32.81% of the area is suitable and available for the development of fruit areas with the largest proportion of 17.48% in the moderately suitable (S2) category.
Zigzag planting method technology was an alternative technology to increase plant population without affecting plant growth and development. The purpose of this study was to determine the productivity of corn with different planting methods, such as the zigzag and the linear planting method applied by farmers on acid dry land in the Lampung area. The research was conducted at the Natar Experimental Station in Negara Ratu Village, Natar District, South Lampung Regency, Indonesia from March to June 2020. The study used a two-factor randomized block design, namely the hybrid corn varieties (NK Sumo, NK 22 Jumbo, and NK Super) and the planting methods (zigzag and linear planting methods). Observations were made on ten plants per sampling plot, which were determined randomly. The results showed that the zigzag planting method produces a higher yield (8.16 tons/ha) compared to the linear planting method (4-5 tons/ha grain yield). Moreover, the zigzag planting method increased the plant population by 80% without disturbing plant growth and development. The zigzag planting method was able to increase corn production by 30-40%.
Soybean is a commodity which is less desirable for farmers to be planted yet it has an increasing high demand for processed food products made from soybean (tofu, tempeh, soy sauce, soy milk, etc.). As a strategic commodity,innovations are needed to provide solutions in order to maintain soybean production, especially in dry land. The purpose of this study was to assess the level of production of several soybean varieties grown using the intercropping system (turiman) with corn on suboptimal dry land. The study was conducted in East Lampung during the 2nd planting season from December 2019 to March 2020. The soybean varieties planted are Dena, Devon, Anjasmoro, and the local one (Tanggamus). The varieties of corn planted are the local existing one. The intercropping system used a corn-soybean pattern of 2 rows of corn and 7 rows of soybeans (Jale 2-7). The corn planted with zigzag pattern. The land area used for intercropping crops is 1 ha. The results showed that the intercropping system between soybeans and corn provided optimal soybean and corn production. The average soybean production was 1.548 kg/ha. The highest soybean production was the Devon variety (2,141 kg/ha) intercropping with corn (BS-18). Meanwhile, the Anjasmoro variety yielded 1.249-1.775 kg/ha, Dena variety yielded 1.428-1.541 kg/ha, and the local Tanggamus variety yielded 971-1.790 kg/ha. Corn production was 11.879-18.672 kg/ha of wet shelled corn. The average corn production was 15.110 kg/ha. The corn-soybean (Jale 2-7) intercropping system was able to optimize the use of dry land based on rainwater irrigation. This innovation contributed to the improvement of the cropping index from CI = 100 to 150-200.
