Abstract

Firmansyah et al. 2012. Suitability of Tidal Swamp for Rubber Plantation in Three Villages of Ex Rice Mega Project, Pulang Pisau Regency, Central Kalimantan Province. JLSO 1(2):149-157. Since 1920, tidal swamp has been widely developed for rubber plantation. Land rehabilitation of ex Mega Rice Project has attracted local community to cultivate the land for rubber plantation. The purpose of this research was to determine land suitability classification for rubber in tidal lowland areas located in three villages (Anjir Pulpis, Jabiren, and Sigi) in Pulang Pisau Regency wherein several types of soil were found, namely Sulfaquept, Endoaquepts, Dystrudept, and Haplohemist. The results indicated that there were several limiting factors to rubber plantation in tidal lowland, i.e. rooting condition, toxicity, nutrient retention, and peat land fire hazard. Actual land suitability classification felt into not suitable (N1) except Dystrudept of Jabiren which was classified as marginally suitable (S3). Improvements to overcome these limiting factors were required up to medium-high level. Low improvement level might not enhance land suitability class. Medium improvement level enhanced marginally suitable (S3) to moderately suitable (S2). Whilst, for high management level, it could enhance moderately suitable (S2) to highly suitable (S1). However, the development of tidal lowland for rubber plantation needed support from the government, especially the costly improvement of poor drainage system.

Nurhayati, N., Swastika, S., Fahroji, F., Yuliani, N., Widyanto, H., Ritonga, E., Jubaedah, J., & Lbs, A. (2023). Peatland amelioration and productivity performance of various new superior varieties of corn (Zea mays L.). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang  21 Oktober 2023. (pp. 54-64).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Peatlands are organic soils that have varied characteristics and generally have low fertility. Corn plants growing on peat often experience problems in terms of nutrient availability. This research aimed to determine the productivity performance of several New Superior Varieties (NSV) of corn on peatlands treated with ameliorant. The research method used Factorial Randomized Block Design with 2 factors and 3 replications. The first factor is the corn variety and the second factor is the type of ameliorant. The ameliorant used was sourced from agricultural waste, namely empty palm fruit bunch compost, chicken manure compost and rice husk biochar. Observations made included peatland characteristics, plant growth, corn production, and farming business analysis. The thickness of the peat ranges from 40-60 cm, classified as shallow peat with sapric peat maturity level. The results of the study showed that there was no interaction between the provision of ameliorant and corn plant varieties on the vegetative growth of corn plants. The highest cob length was obtained for Nasa 29 and Bima 20 Uri varieties. The hybrid corn varieties Nasa 29, Bima 2, and Bima 20 Uri were able to adapt and produce on peatlands, respectively 2.8 t/ha; 3.2 t/ha, and 3.3 t/ha. NSV of corn technology and peatland amelioration can increase farmers' income.
