Abstract

Making acid sulphate soils as paddy fields is a wise choice because it can prevent the soil from oxidizing which occurs in acidification of the soil. The use of biochar as an amendment to the land has long been known since the discovery of terra preta since 1870 in the Amazon Basin as the Amazon dark earth. Because biochar soil amendments are rich in C-organics, have a buffering capacity and can increase soil acidity, are able to absorb heavy metals, and are able to retain water and nutrients for soil organisms. Meanwhile, lime has also been known as an acid sulphate soil amendment in Rome 2000 years ago to balance the acidity in agricultural land. This has been practiced for centuries until now. Though compost or organic soil can be traced more than 2000 years ago. Soil organic matter (SOM) is formed from the remains of animals and plants. It contains C and many nutrients such as N, P, and K. Based on the description above, the author wants to combine the three ingredients in the review, especially in relation to acid sulphate soils.

Abstract

Cultivating of melon particularly in Central Kalimantan has been widely undertaken by farmers, however, the yields have not been able to meet the melon needs of Central Kalimantan's community. One of the breakthroughs in overcoming the problem is by growing melons on swamp floating beds, namely ambul technology. Ambul is growing media from decomposed floating aquatic plants, constructed with bamboo or wooden as a frame, that is let floating on waters. The ambul based on the consideration that the community lacks access to land for most of the year, which reduces opportunities for growing crops. The research design used was Split Plot Design with three kinds of aquatic plants as the main factor namely Eichornia crassipes, Salvinia molesta, Eleocharis palustris, and two melon varieties as subplot factors specifically Action 434 and Amanta. The results showed that the Amanta variety grown on S. molesta media produced the highest value of crop length on 1, 2, 3 weeks after planting (WAP). S. molesta was the best planting media for enhancing flowering by 11.43 days after planting (DAP) and weight of fruit (3.18 kg per plant. The variety of Amanta also had the highest value of root dry weight of 1.33 g per plant and fruit weight of 2.08 kg per plant.

Abstract

Swamp areas provide basic needs for local communities living in wetland areas, especially in the Banjar regency, South Kalimantan. Indigenous people called Banjarese or the Banjar are consuming wild swamp vegetables and processing them into traditional food combined with rice. The potential use of swamp plants for vegetables by Banjarese was investigated through an ethnobotanical study. The vegetables were obtained from three selected lowland swamps located in three villages of Banjar regency namely Panjambuan, Sungai Batang and Sungai Tuan Ilir. Wild swamp vegetables were identified using a semi structured questionnaire technique and the 72 key respondents were selected by a purposive sampling based on their interaction with swamps. Then they were classified into gender, and 4 groups based on their ages to determine knowledge level (Mg) in utilizing wild swamp vegetables. After that, their level knowledge was tested based on gender and ages using Kruskal Wallis test. Mann Whitney U-test was applied to distinguish the difference of knowledge level from ages and sex. The findings observed were six wild swamp vegetables used by Banjarese such as water spinach Ipomoea aquatica, genjer Limnocharis flava, hairy water lily Nymphaea pubescens, water mimosa Neptunia oleracea, taro Colocasia esculenta and swamp fern Stenochlaena palustris. All parts of the plants were used except for the roots. Leaves were preferably cookedwith 44,5% in comparison toother parts of plants like stem, flower, tendril and corm. Water spinach was frequently consumed by Banjarese compared to other plants. The knowledge level of local people was 67,84 categorized as a middle level and an elderly more than 60 years old had the highest knowledge level in using swamp plants compared to other groups. Moreover, women had better knowledge rather than men to utilize wild swamp plants for food.

Abstract

Tidal lowland has a great prospect due to its vast area to support the improvement of national food security and the development of agribusiness system. Based on these potentials, it is necessary to study water management the physical dan chemical characteristics of soil on tidal land at Telang Jaya, South Sumatra. The aim of the study is to develop micro water management in the field level  for rice cultivation, and to evaluate the soil fertility in relation to the rice production.  The soil properties can be used to determine the level of soil fertility and the land management problem at the area. Research method was done by experimental research in combination with survey and monitoring. Rice was cultivated in tertiary block and the ground water table fluctuation was record in daily bases. Soil samples were taken from 0-20 cm depth (the root depth for common food crops) and then analyzed at the laboratory. The result had showed that the soil fertility status at Telang Jaya was low to moderate. The limiting factors of soil fertility found in this study were consisted of low nitrogent content, low C-organic content and acid soil condition (low bases and pH). Ground water taken at  February to March was maintained on 10 to (-10) cm related to the soil surface. It was sufficient for crop water requirement. Water management objective for second rice was mainaly for control drainage during the intial stage, and retain rainfall water. Pumping irrigation was required during Elnina climatic condition at generative phase. By proper water management system rice production could achive 5 ton/ha.

Abstract

fires in Indonesia. About thirty percent of the total fires are spread in Central Kalimantan Province. Symptoms of climate change in the form of increasingly frequent weather and extreme climate phenomena support the severity of forest and land fires which results in increased release of air pollution gases. In 2015, the peak fire months had emitted a high concentration of air pollutant gasses and causes hazardous air pollution. This study aims to investigate the latest severe fire occurrence and haze conditions in Central Kalimantan. Hotspot data was from 2006 to 2017, visibility data were from four times of El Niño event, Particle Matter Size 10 (PM 10) data and Pollution Standard Index (PSI) was from very strong El Niño in 2015 comparison to La Niña in 2016/2017. The results showed that the top incidents occurred not only very strong in 2015 but also weak El Niño in 2006. The most of dense hotspots density in the last twelve years (> 50% of fires in the area) found in peatlands in Pulang Pisau, Palangka Raya and Kapuas.  Palangka Raya's case, dangerous of APSI with PM10 concentrations of more than 500 µg m-3 occurred for 2 (two) months, from the end of August to the early of November 2015. The maximum peak concentration of PM10 is as high as 3000 μg m-3, which is higher than other fire years. Based on the data obtained, the haze was blanketed Palangka Raya was getting thicker at the end of October. As a result, visibility is decreasingly limited, only around 200 to 900 m during the peak season and air pollution-related-peat fire. Thus, this severe condition could rose multiple effects, which will exacerbate climate change, environmental sustainability and the livelihoods of thousands of peoples.

Abstract

Successful restoration and fire prevention in peat landscapes require full rewetting and permanent revegetation for optimal water retention. The ecological and socio-economic heterogeneity of these landscapes calls for integrated approaches based on participatory zonation and locally appropriate business models. Primary activities in deep-peat core zones are blocking of drainage canals and revegetation; in shallow-peat buffer zones, forestry and agroforestry on fully rewetted peat, aquaculture, and duck farming; while on surrounding non-peat mineral soils, more intensive tree plantations and agriculture. Community-oriented enterprises require private investment, including microfinance. Blended public and private investment is needed for core-zone restoration. Assuming restoration costs of USD 250-1,000 per ha on moderately drained peat, with emissions of 40tCO2/ha/year, carbon finance could pay for the cost of restoration in under 10 years if emissions are fully or largely abated. To stimulate investment in multiple peatland landscapes we propose a provincial ‘enabling platform’ to support participatory zoning, project design, and monitoring based on common standards and methodologies; technical assistance and incubation for project start-up; multi-stakeholder support for enabling policies, plans and institutions; strengthened finance mechanisms and bundled investments for large and small enterprises; and robust scientific support and knowledge exchange.
