Application of Several Types of Rhizome Powder in Controlling Sitophilus Oryzae L. Pests in Local Siam Mutiara Rice
Full text linkRice is the staple food of the Indonesian population. Siam Mutiara is the preferred local variety of rice in South Kalimantan. Sufficient rice availability must be supported by a rice surplus as food reserves.The main problem with rice storage is the emergence of Sitophilus oryzae L. Therefore it is necessary to control the pest. Non-toxic botanical pesticides can be applied to control S. oryzae. This study aimed to determine the effect of the application of several types of rhizome flour on the mortality rate of S. oryzae, population development of S. oryzae, and weight of Siam Mutiara rice to obtain the most effective rhizome flour. The research was conducted in March 2020 - August 2020 at the Agroecotechnology Production Laboratory, Faculty of Agriculture, Lambung Mangkurat University. The one-factor Completely Randomized Design method (CRD) was used by treating z0 (control/without rhizome powder), z1 (red galangal rhizome powder), z2 (kencur rhizome powder), z3 (red ginger rhizome powder), and z4 (rhizome powder combination). The treatment was repeated 4 times so that there were 20 experimental units. The results showed that the application of red galanus rhizome powder, sling rhizome powder, red ginger rhizome powder, and rhizome powder combination was able to control the population development of S. oryzae and weight damage of Siam Mutiara rice due to S. oryzae pests. The rhizome powder that was most effective in controlling S. oryzae was z1 (red galangal rhizome powder) with a mortality percentage of 32.50%, population of 7 individuals, and rice weight of 99.96%; z2 (kencur rhizome powder) with a mortality percentage of 65%, population of 3 individuals, and rice weight of 99.97%; z3 (red ginger rhizome powder) with a mortality percentage of 62.50, population of 4 individuals, and rice weight of 99.96%; and z4 (rhizome powder combination) with a mortality percentage of 47.50%, population of 5 individuals, and rice weight of 99.95%
Soil Acidity Soil Acidity Mapping of A Swampland Planted with Rice in Ampukung Village, Kelua District, Tabalong Regency: Soil Acidity Mapping of Tidal Swamp Lands
No full textTidal swamp land is one type of wetland in South Kalimantan, where the water level is influenced by the season/rainfall. Based on the puddle level and duration, tidal swamp land has three typologies, namely shallow tidal swamp, middle tidal swamp, and deep tidal swamp. The wetlands in Ampukung village are classified in tidal swamps. Most of the tidal swamps have been utilized for agricultural activities, especially rice. Till now, rice farming in the tidal swamps of Ampukung village has not experienced any significant problems. In 2016, the rice harvest in Ampukung village exceeded the target of South Kalimantan. This success is considered to be increased by planting twice a year. However, some issues need to be addressed regarding the characteristics of the land in Ampukung village. Soil fertility, especially soil acidity, is one of the limiting factors in the utilization of tidal swamp land. Therefore, it is necessary to identify the acidity of the soil in the tidal swamp of Ampukung village. The acidity data is basic information to determine the condition of soil fertility to achieve the target of planting rice twice a year. This information will be presented in the form of a map to assist users in interpreting the research data. This study found that the soil pH in the tidal swamp lands of Ampukung Village, which was planted with rice, was highly acidic and homogeneously distributed

Production and Nutrient Quality of Rice Straw of Local Rice Varieties From South Kalimantan
Full text linkA survey and laboratory study was conducted to estimate rice straw production of local rice varieties from South Kalimantan. Two local rice varieties (Siam Adil and Pandak) cultivated in a tidal swamp paddy field in Tanah Laut regency were harvested at the same time to estimate the dry matter production of rice straws and to obtain the rice straws samples. Rice straws samples were analysed to determine the percentage of botanical parts and nutrient contents, including the contents of dry matter, organic matter, crude protein, and crude fiber. Results showed Siam Adil rice straw had a lower percentage of leaf but had higher percentage of stem compare to Pandak. The botanical fraction of Pandak was similar to the improved rice variety (Ciherang). Siam Adil produced higher rice straw dry matter (7.95 tonnes/ha) compare to Pandak (5.83 tonnes/ha). There were no significant differences in the contents of dry matter, crude protein, and crude fibre of both local varieties. However, local rice straws had lower crude protein and higher crude fiber contents compared to the improved rice straw. In conclusion, local rice varieties potentially produced higher rice straw biomass but had lower nutrient quality. Thus, pretreatment is necessary to improve the utilization of local rice straw as a ruminant feed
