Abstract

Lack of the element Zn in the body was one of the serious problems of malnutrition in Indonesia because it reduces endurance, productivity and quality of human life, and was one of the factors causing stunting. Stunting is worrying because it can cause problems with a child's growth and development, which is characterized by the child's height being below standard. One of the factors causing stunting is reduced consumption of zinc (Zn), especially in pregnant women and children. Deficiency of the element Zn in the body can be corrected by consuming foods that contain Fe and Zn. This writing aims to inform and convey the idea that one of the efforts that can be made to reduce stunting rates is through the development of Biofortified rice which will produce nutritious rice. To evaluate the impact of rice development, an evaluation was carried out on rice production and its effect on reducing stunting in several districts in South Sumatra. The method used was interviews, recapitulation of primary and secondary data. Biofortified rice cultivation efforts had been carried out in South Sumatra since 2021 in South OKU (1000 ha), in 2022 in Lahat (1000 ha), and in 2023 in eight districts (8000 ha). In general, Biofortified rice production in South OKU Regency (5.28 tons dry Grain/ha) and Lahat Regency (5.08 tons Harvested Dry Grain/ha). Based on the 2021 Indonesian Nutritional Status Survey (INSS) saw a decrease in the average prevalence of stunting in South Sumatra in 2022 to 18.6%, which decreased from 24.8% in 2021, including in Biofortified rice development districts. Based on the fact that the development of Biofortified rice can be an effort to reduce stunting, The Regional Government was increasingly expanding rice cultivation in almost all districts/cities.

Abstract

One of the efforts to facilitate the way of taking rice seeds from the nursery media is to use plastic sacks instead of  directly from the soil.  To obtain the best planting media, experiments have been carried out on the no tidal swamp Rice   Fields, Pemulutan Village (3°05'42.7"S, 104°44'01.7"E), Ogan Ilir Regency, South Sumatra Province from June to August 2022.  The design method used was a Randomized Block Design. The treatments tested were four compositions of planting media mixtures, namely a mixture of soil with chicken manure, a mixture of black sand and chicken manure, a mixture of white sand and chicken manure, and black sand. The media composition ratio was 1:1 (V/V). All treatments were replicated three times to obtain 12 units. The seeds used are rice seeds of the Inpari 32 variety. The size of the seeding media made from plastic sacks was 160 cm x 100 cm, and the thickness of the entire planting media composition was 3 cm.  The plastic sacks used had a length of 180 cm and a width of 112 cm, and were used as a pad for a rice nursery which were 160 cm x 100 cm, and the thickness of all media compositions was 3 cm. The composition of the four treatments prior to the study showed that the pH was relatively the same (6.9-7.0) and the EC valuesvaried greatly (207-7734 mS), and at 14 day after plant (DAP) there was a decrease in pH to 4.3-5.3 and EC decreased drastically with narrow variations being (170-384 dS/cm).  Changes in the chemical properties of the media certainly had an impact on seed germination (70-90%) at 14 DAP of each media, and it turned out that the composiion of the type of planting media had  significant effect on sprout height, number of leaves, leaf length and sprout root length. In general, it can be concluded that the best media composition for rice germination is soil and chicken manure.

Abstract

In Indonesia, onion cultivation uses bulbs, which disrupts stocks of consumtion and trade quite significantly. One way to reduce the need for bulbs from onions is to use True Shallot Seed (TSS). Onion of TSS can reduce production costs, and is practical in shipping compared to bulbs. One of the activities in the cultivation of TSS is the preparation of strong, uniform and healthy of seedling. This study aims to examine the appropriate composition of organic matter as a planting medium to accelerate the germination time of various cultivars of TSS. The planting medium tested was a mixture of soil, rice husk, cocopeat and sawdust. This study used a complete randomized block design which was arranged in factorials. The first factor was the variety and the second factor was mixing of organic matter. Mixing organic matter with the soil before planting onion seeds led to an increase in soil pH from 0.77 to 1.51. Mixing soil with organic matter before implementation increased the pH of the media, CEC, WHC, and decreases the bulb density. After germination, the husk and cocopeat mixture showed a pH (5.9), CEC (1.62 mS.cm-1), bulb density (0.3 g/cm3) and WHC (162%). The combination of rice husk and cocopeat as the growing medium (4,9 days), the Sanren cultivar (7,3 days) exhibited the fastest germination and seedling growth rate compared to other cultivars and mixed growing media.
