It is believed that the agro-industrial sector, which uses cassava as a raw material, has more advanced farming technology for improving cassava production. Lampung province in Sumatra Island, Indonesia, is one of the cassava production centers for industrial raw materials, with a planted area of 256,632 ha in 2018. The planting areas are acid soils of Ultisols, Inceptisols, and Oxisols with pH levels ranging from 4.5 to 5.0. Acidic soils have a complicated set of plant growth-limiting constraints. Essential nutrients for plant growth, such as N, P, and K, as well as other cations, are often low due to leaching, nutrients fixed by Fe/Al oxides of clay minerals, and low soil cation exchange capacity. In these acid soils, cassava production ranges from 8 to 15 t ha−1 for traditional farming, 20–24 t ha−1 for semi-developed farming to 25–35 t ha−1 for advanced farming. Meanwhile, with numerous technological advan...

The food sovereignty of a nation would be viable provided that the natural resources essential for plant growth are available and one of them is water. However, the increase of water demand far exceeds its availability, thus water shortage for agriculture with, as water is also needed by other organisms. As a tropical country, Indonesia has sufficient water supplies from both rainfall and groundwater. With good water management and conservation strategy, it should suffice the demand. Therefore, save the water movement as part of water sustainability program would highly contribute in achieving sustainable food production hence food sovereignty in the long run.

Today nutmeg is one of the region's export commodities. The quality is an important factor in global nutmeg trade. The aim of this study was to assess nutmeg development prospect by analyzing the land characteristics and the quality of nutmeg. The study utilized a survey method to characterize the land and performance of smallholder nutmeg plantations, to communicate with farmers and to sample some nutmeg seeds for quality analysis. The survey was carried out in four subdistricts of the main nutmeg producing areas in Tanggamus Regency, namely Kota Agung-Timur, Gisting, Semaka, and Air-Naningan, in each area, 2-3 smallholder nutmeg plantations were assessed. The areas suitable for nutmeg development are Kota Agung-Timur, Gisting, and Semaka. The main supporting factor is water availability throughout the year, whereas the limiting factor are air humidity >75%, low organic C and CEC ≤16 cmol (+)/kg of soil, and erosion hazard due to a slope of >15%. Nutmeg productivity has potentials to be improved through technological innovation as current nutmeg cultivation is still conventional and does not use superior seeds, fertilizer and postharvest technology. On the other hand, the nutmeg seeds qualities have met SNI standards such as specific gravity, refractive index, optical rotation, soluble in alcohol, and chemical properties such as myristicin, α-pinene, sabinene, and safrole. Methyl eugenol is below the threshold of the European Pharmacopoeia standard and the α-pinene is better than nutmeg essential oil of produced from other regions.
