Assessment and Prediction of Canal Erosion on Tidal Swamp Delta Telang I, Banyuasin Regency, South Sumatra

Abstract Development of maize hybrid for tidal swampland was initiated by selecting and combinate some superior line genotypes that tolerate to the restrictions in target environment. This study aimed was to evaluate the capability of ten maize lines result of selection on tidal swamp acid sulphate soils to obtain GCU, GCA, and heterosis values based on parental yield averages. The experiment has consisted of ten fine line genotypes which have selected in 2019 at the tidal swamp. Each parent was crossed in half-diallel combination, resulting in 46 entries, including the inbred parents. The entries were planted in a randomized complete block design with three replications. The research was conducted on Bajeng Research Station Experiment 5°18’S and 119°30’E from September 2020 to January 2021. The result shows that GCA ability and SCA ability was significant to yield in the form of grain (15% moisture content), the number of ear per plot, ten ear weight, ten corncob weight, ear harvested weight, 1000 seeds weight, plant height, ear length and the number of seed per ear. Grain yield of W6xW9 crosses obtains the highest value of 9.36 tha−1, non-significantly different to hybrid check P35 (9.35 tha-1). The highest GCA value in the grain yield character was obtained on W9 parental line (0.64**). The highest SCA was obtained on the crossing of W7 x W8 (2.61). The highest heterosis value was revealed in W5 x W10 hybrid (4.80). However, W7 x W8 crossing heterosis value was 2.34, indicate that a high SCA effect did not usually generate high heterosis. To perform high heterosis value, W10 was good as female parental.

Tidal Swamp

Muara Sugihan is one of the tidal swamp areas for rubber plant cultivation in South Sumatera. A preliminary survey of the land suitability in 2012 described that there are two main problems, the shallow groundwater problem and low pH (2,87-3,05) between 40-100 depth that indicates the presence of pyrite layers. In the prior of planting, the water drainage has been done to maintain the water table. However, the water drainage was excessive so that water table reach 66 cm from soil surface hence aerobic condition resulted in oxidation of pyrite layer. The method used in this study was survey method consist of measuring the girth of 2 years old rubber plants and sampling of soil, leaves, and water on the trench and the river which indicated the presence of pyrite layers on tidal swamp area, Muara Sugihan. The result showed that the growth of the rubber plants was inhibited, where the girth was 10 cm, while on optimal dry land they normally reached 18 cm. Leaf nutrient analysis showed there was deficient of P, K, and Zn, while on soil analysis showed a low P content. The pyrite was leach from the soil and accumulate into water drainage will lead to low pH of water. This problem can be solved by water management improvement.

Abstract. Ikhsan Z, Hidrayani, Yaherwandi, Hamid H. 2020. The diversity and abundance of Hymenoptera insects on tidal swamp rice field in Indragiri Hilir District, Indonesia. Biodiversitas 21: 1020-1026. Hymenoptera is one of the four largest insect orders and it plays a vital role in human life as pollinators, parasitoids, and predators. Hymenoptera parasitoids are particularly important as agents of biological control of pest. The objective of this research was to study the diversity and abundance of Hymenoptera on tidal swamp rice field in Indragiri Hilir District, Riau Province, Indonesia. Samplings were conducted in 3 sub-districts of rice production centers, namely Batang Tuaka, Keritang and Reteh, using four trapping techniques (i.e. insect net, malaise trap, pitfall trap, and yellow pan trap). Shannon diversity index (H '), Krebs evenness index (E), and Jaccard similarity index (Is) were calculated. We found 4,701 individuals consisting of 39 families and 319 species of Hymenoptera at the three studied areas. Tidal swamp rice in Indragiri Hilir District had a high species diversity of Hymenoptera parasitoids and Hymenoptera predators, but a moderate species diversity of Hymenoptera pollinators. Species diversity and evenness of Hymenoptera parasitoids and predators were higher in Keritang than in Batang Tuaka and Reteh. The families of Formicidae, Braconidae, Ichneumonidae, and Scelionidae had the highest number of species, while Formicidae, Scelionidae, Diapriidae, and Braconidae had the highest number of individuals. Based on these findings, the abundance and diversity of Hymenoptera insects in Indragiri Hilir District have the potentials to be developed as biological agents to control pests on tidal swamp rice in this area.

The objective of this research is to analyses the allocation of farmer household resources in tidal swamp area. The survey method was used to collect farmer data located in tidal swamps land villages with acid sulphate land, peatyland,. and potential land typologies in South Kalimantan. Quantitative analysis of data was carried out using linear programming model and sensitivity analysis, utilizing the BLPX 88 program.The findings of the analysis showed that villages allocated resources differently with the implication that incomes earned by the villages differed from one village to the other. However, it was found out too that optimal solution showed the need for the continuation of rice growing in the areas. Farmers who were located in potential areas where tangerine were grown produce higher incomes than the other two villages. To replicate the cropping pattern farmers in potential land in acid sulphate land and peatyland, resulted into a drastic increase in income earned by farmers

Main Plot

Corn is one of the important food crops and feeds in the world. Conversion of agricultural land into non-agricultural land is one of the major causes of the decline in corn production. Saturated soil culture (SSC) is a cultivation technology that gives continuous irrigation and maintains water depth constantly and makes soil layer in saturated condition. This technology can prevent pyrite oxidation in the tidal swamp. This research aimed to study the effect of temporary fl ooding under saturated soil culture on the growth and productivity of corn. The research was conducted at Karya Bhakti village, Rantau Rasau, Tanjung Jabung Timur, Jambi Province, Indonesia. The experiment used a split plot design with three replications. The main plot is fl ooding condition, consisted of 1) saturated soil condition continuously, from planting until harvesting time (as control), and 2) saturated soil condition from 0 to 10 DAP (Days after Planting) + fl ooding from 11 to 13 DAP + saturated soil condition from 14 to 28 DAP + fl ooding from 29-31 DAP + saturated soil condition from 32 DAP until harvesting time. The subplot is corn variety, “Sukmaraga”, “Bisma”, “Pioneer 27”, and “Bima 20”. “Pioneer 27” had the highest productivity of 9.33 t.ha-1. Corn varieties with moderate tolerance to temporary fl ooding were “Sukmaraga” and “Bisma”, whereas “Pioneer 27” and “Bima 20” are sensitive to fl ooding.
