Rice 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%.

ABSTRACT   This research aimed to determine the effects of compost applications on ex-mining lands by using chinese cabbage as indicator. The experiments were conducted at the Faculty of Agriculture greenhouse and the soil and compost analysis were done at the Soil Chemistry and Fertility Laboratory for a duration of two months. The research employed a Completely Randomized Design method with 5 treatments repeated 3 times to get 15 experimental units. The analysis on ex-mining soil revealed that it contained only trace amounts of soil nutrients N, P, and K. The laboratory analysis on the compost sample resulted in a C/N ratio of 11.87 which suggested that the compost was mature and ready to be used. The Analysis of Variance on research data showed that compost applications did not affect plant height between treatments at each weekly observation, and similarly did not affect leaf quantity and fresh weight at harvest time.  However, the research found that the compost applications tended to improve plant height, leaf quantity, and fresh weight of plants at harvest time.  The minimal effect of compost applications between treatments suggested that the plants did not utilized the nutrients supplied by the compost in their early stages of development.  Moreover, it was also suspected that the compost applications had not been sufficient in supplying the soil nutrients needed by the plants to ensure proper growth which ultimately affected the fresh weight of the plants at harvest time.
