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.

The study aimed to determine the rendement of charcoal and wood vinegar and to identify wood vinegar chemical compounds made from ironwood deliquent waste. The study was carried out by using charcoaling facilities at the charcoaling center in the village of Asam – Asam. The charcoal and wood vinegar rendements were determined after ironwood delinquent waste was heated for 21 days with a temperature of approximately 400 - 600 oC. The results showed that the rendement of the charcoal and wood vinegar were 14.02% and 0.05%, respectively. The research with wood vinegar characteristic before purification was pungent, however after purification, the results did not sting; color pH before purification was blackish-brown, however after purification it was pale brown yellow; the specific gravity before purification was 1.012 and after purification, it was 0.97; the pH before purification is 3.63 and after purification 3.41; and acid content before purification was 3.73% and after purification it was 3.66%. As a whole, the physics test of wood vinegar is categorized in Japan standard, however, the color only before purification is not standard. There are five chemical compounds identified in wood vinegar both before and after purification.

The objectives of this study were to determine the heavy metals contents (Cd, Pb, Cu and Zn) in the body of some freshwater fish and to examine the histopathological changes of some organs. The fish were obtained from Payau River located in Anggana, Kutai Kartanegara District, East Kalimantan, Indonesia. There were four (4) species examined namely: Glass Fish ( Chanda sp), Croaker ( Micropogenias undulatus ), Lais ( Kryptopterus cryptopterus ), and spotted catfish ( Arius maculatus ). Lead (Pb), Cadmium (Cd), Copper (Cu), and Zinc (Zn) were being analysed in the gills, livers, and the muscles of the fish. The results showed that Pb and Cd were still low and fulfilled the the quality standard based on Indonesian National Standards Agency (INSA, 2009) and Directorate of Drug and Food Control No. 03725/B/SK/VII/89. Cadmium concentration in the fish organ was < 0.003 mg/kg (Max. limit of Quality standard is 0.1 mg/kg) and Pb concentration was <0.002 mg/kg (Quality standard is 0.3 mg/kg).

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 Nino event, Particle Matter Size 10 (PM 10) data and Pollution Standard Index (PSI) was from very strong El Nino in 2015 comparison to La Nina in 2016/2017. The results showed that the top incidents occurred not only very strong in 2015 but also weak El Nino 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.

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.

The water demands for agricultural purposes are increasing along with the population growth. Unfortunately, the water source is not sufficiently available nowadays. Furthermore, the quality of available water is more deteriorated due to the contamination from many sources such as households, industrial areas and other activities. Water board Scheldestromen handles 16 wastewater treatment plants located in Province of Zeeland in The Netherlands. The total production of treated effluent water from 16 wastewater treatment plants is 50 million annually. Quality of the effluent is relatively good, however, some potential risks related to the number of pathogenic microorganism and some trace metals are still there. The treated effluent is mostly discharged to river near to the treatment plant. The high amount of effluent discharge would potentially to be re-used for fulfill the demand for agricultural water. Therefore, this study aims to evaluate the feasibility of treated effluent from one of Walcheren wastewater treatment plants located in Ritthem, Province of Zeeland. This study uses the method of Multi Criteria Analysis (MCA) for looking the best way to re-use the effluent for agricultural purposes. The MCA questionnaire was developed based on the thorough literature review of effluent reuse. There are 6 criteria that need to be weighted and 6 scenario alternatives that need to be scored for the MCA questionnaire. The result show that the effluent water contained pathogenic bacteria (E.Coli) and some trace metals (Ni and Cu) more than suggested by FAO standard.

Micro, small and medium entrepreneurs are the economic drivers at the lower levels and they generally rely on the ability of human resources. Nevertheless, they will be extraordinary if all their potential is nurtured, explored and developed because the factors that trigger success are not only determined by external conditions, but also internal conditions. Among the internal factors that spur one's success are locus of control, learning, and adversity quotient. This study aims to examine the partial and simultaneous effects of locus of control, learning, and adversity quotient on business success. The research respondents were a foster group of entrepreneurs under Banjarmasin, total 1881 people. With the Slovin formula, 100 respondents appear. The results of the study showed partially that the t value of the effect of locus of control on business success was 3.046. T value calculated the effect of learning on business success was 2,150. T value calculated the effect of adversity quotient on business success was 4.924. Thus, adversity quotient had the most dominant influence on business success. The correlation coefficient of 51,944 and the probability value between variables of 0,000 indicate a significant effect between locus of control, learning, and adversity quotient on business success simultaneously. Finally, it was found that R square 0.619 means 69.1% where business success can be explained by the locus of control, learning, and adversity quotient variables; the remaining 30.9% was explained by other factors. The research findings that the guidance provided must be ongoing, not only with training, but also need to foster mental and spiritual change as a true entrepreneurship through strong locus of control, continuous learning, and high adversity quotient.

The research findings that the guidance provided must be ongoing, not only with training, but also need to foster mental and spiritual change as a true entrepreneurship through strong locus of control, continuous learning, and high adversity quotient.","PeriodicalId":30661,"journal":{"name":"Journal of Wetlands Environmental Management","volume":"19 1","pages":"21-32"},"PeriodicalIF":0.0,"publicationDate":"2020-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90146949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Understanding the population structure is one of the best ways to recognize the population in a plant as a whole. The riverside Maluka of Tanah Laut District is the swamps and river found herbs having an important role to play in maintaining the structure of the soil from the erosion of the river running on the area. Employing the descriptive method, this research attempts to describe population of structure plants of the riverside Maluka. The sample of structure plants are those on both edges of the riverside, namely: 1500 meters long and 2 meters wide. The data were collected by using the transect The results showed that there were 13 plants species trees with the different population structure. There are four plants with population structure of polygonnamely; Mangifera indica , Flacourtia rukam , Antidesma Ghaesembilla , and Melaleuca cajuputi . There are six plants of width-based population structure of width, namely; Gluta renghas , Acacia auriculiformis , Syzygium sp., Syzygium guineense , Pisonia sp., Cassia alata . There are two plants in the forms of basin or pitcher, namely; Mangifera casturi and Fagraea crenulata . Plants that have population structure of reversed polygon is called Lagerstroemia speciosa.

Agriculture productivity of tidal lowland reclamation areas in South Sumatra is still low. It leads to the increasing of agricultural land conversion into plantation areas. Controlling the water table is the main factor in the tidal lowlands; this research aimed to develop micro drainage system in tertiary block for controlling water table under wet condition. Watermelon was used as a crop indicator and planted in mid- March 2015. The location of the research was in a tidal lowland agriculture with land typology B, where the tide can only be as irrigation during the rainy season. The method of this research was surveying and monitoring. Groundwater observation, measurement value hydraulic conductivity and land drainage applications were included in the field activities. The design of land drainage used an intensive shallow drainage concept; the effect of the depth of the water table to water status was evaluated by the UPFLOW model. A micro drainage on tertiary block was used by 8 m drain spacing, with channel depth of 20 cm. The results showed that the tertiary gate operation was maximum drainage option. The water table depth was 25 cm in soil depth.The watermelon crops grew well and production reached 20 t ha-1 .
