This research aimed to analyze potential supply and removal of biomass and soil nutrients induced by different vegetation on peatlands. The research was carried out in peats dome of the catchment area of the Sibumbung River and the Burnai River in Pedamaran Sub-Districts, OKI South Sumatra. The research method used field survey of case studies of four natural phenomena (swamp grass, bush swamp, pulai peatlands, and peat forest). The research resulted that the highest production and harvest of biomass came from peat forest, pulai peatland, bush swamp and swamp grass. The highest biomass supply to the soils were given by the peat forest, pulai peatland, bush swamp and swamp grass (around 12,545; 11,593; 7,491 and 5,313 kg/ha/year respectively). The more varied the vegetation type, the higher the supply of soil nutrients. Swamp grass and bush swamp have low vegetation diversity and are mostly dominated by alang-alang. Swamp grass and bush swamp showed the same pattern and the order of nutrient supply in the highest sequence is K, Ca, N, Mg, Ca, and P. The supply order of soil nutrients (peat forest and pulai peatland) showed a similar pattern, namely from the highest content of Ca, N, K, Mg and P. Pulai vegetation can be recommended for a paludiculture system because it resembles almost the peat forest in producing biomass and soil nutrient supply to the soils and is originally native plant from peatland.

“Do We Care Enough?”- A Critical Analysis of the Legal Duty of Care Contained in the National Environmental Management Act and Its Application to Wetland Restoration Bramley Jemain Lemine

AbstractSouth African wetlands are disappearing at a rapid rate. Considering the vital functions they provide, they require optimal protection and, where appropriate, restoration. In line with protecting and restoring the environment, section 28 of South Africa’s National Environmental Management Act 107/1998 (NEMA) makes provision for the duty of care and remediation of environmental damage (DOC). This enforceable duty rests upon every person (natural and juristic) to, amongst others, prevent pollution or degradation of the environment or to stop, minimise, and rectify such pollution or degradation by taking certain measures. For wetlands, this duty is bound to the idea of 'ecological restoration’ (ER), which is defined as “the process of helping to recover an ecosystem that has been degraded, damaged or destroyed”. This paper, through the selected theoretical framework for ER, sets out the literature to provide the foundation for 1. the international obligation of restoration; and 2. a critical analysis of section 28 of NEMA through the selected ER framework for wetlands ecosystems. The research reveals the gaps in support of the argument that the DOC principle may lack in addressing the full embodiment of ER and providing the consequences of such failure. Thus, calling for the amendment of section 28 of NEMA (DOC) to include the appropriate provisions and the removal of superfluous and confusing provisions such as ‘significant’. However, there is scope for the improvement and development of ER for the 2024 proposed National Joint Wetland Management Policy..

Tidal lowland reclamation aims to extend food agricultural area. Land clearing was done at Delta Telang II, Kabupaten Banyuasin District, South Sumatra I period of 1981-1982. Most area of Delta Telang II had land typology of B/C and almost half of it already been changed into palm oil plantation. Therefore, the field study had been conducted to determine the potentials and constraints for development of paddy field. The research method was applied study and field experiment. Soil physical properties analyzed were texture, volume weight, and hydraulic conductivity. Rice used in this study was Inpara 3 variety. The research results showed that soil physical properties was appropriate for development of paddy field rice. Controlling of water level in tertiary level by farmers was a key succeeds to provide water for crops. Model of water gate is flap gate type and it is operated dominantly as drainage during rice growth period and only functioned as supply when crops entering generative phase. Average rice production was 7.5 t ha-1. This condition was showed that using proper water management, balance fertilizer application, and adaptive rice variety resulted in successful rice crops cultivation at tidal lowland area and subsequently prevent land functional shifting. Key words: Tidal lowland reclamation, water management, rice.

Greywater is categorized as domestic wastewater with a light pollutant concentration. The discharge of untreated greywater into the environment will decrease the environment quality, especially water bodies. This study aimed to investigate the performance of the combined vertical and horizontal sub-surface constructed wetlands in removing pollutants and recycling the greywater for a clean water alternative. The greywater sample was taken from the discharge point of the Rectorat Building of the Universitas Negeri Malang. The water bamboo plant (Equisetum hymale) was used in the experiment. The vertical sub-surface constructed wetlands dimensions were 50 cm in length, 50 cm in width, and 80 cm in height. While the horizontal one has dimensions 50 cm of length, 30 cm of width, and 30 cm of height. The water flowrate was designed to be 30 ml/min with a residence time of 3 days. The results showed that the hybrid constructed wetlands could reduce the pollutant concentration to meet the discharge consent. The efficiency of removal was TSS by 88% and BOD by 85%.

In general, the credit period is a reflection of the credit risk that may arise provided by the bank to MSMEs to return principal and interest on the loan. The longer the credit term, the higher the risk that may arise, then the bank will charge higher interest compared to short-term credit. The existence of the phenomenon then the method to answer the above problems in the form of field surveys using questionnaires to 93 respondents in the form of Likert scale. The analysis technique used was multiple linear regression analysis. Result showed that MSMEs can manage debt or credit management from BMT Muamalat for its business activities. Each MSMES has different managing abilities. What is meant by the ability to manage credit here is the ability to manage his business after obtaining loan funds from BMT Muamalat.

The Potential of Hand Wash Liquid from Galam (Melaleuca cajuputi) Muh Azhari; Sri Marlina
Journal of Wetlands Environmental Management Vol 10, No 2 (2022): July-December, 2022
Publisher : Center for Journal Management and Publication

Galam (Melaleuca cajuputi) is a typical plant of the peat environment in Central Kalimantan. Galam is used by the community to meet the needs of boards, bridges and other functions. Utilization of Galam (Caulis) causes the accumulation of certain biomass such as leaves. Waste of Leaf Galam can be used to isolate the volatile through the distillation process. These essentials can be used as active ingredients for making liquid hand soap. The liquid hand soap can be an alternative to hand washing soap in the era of the COVID-19 pandemic. The results showed that the organic compounds contained in the volatile using the Gas Chromatography Mass Spectrometry (GCMS) method, such as 1,8-Cineole, 1-Phellandrene, 2 Beta-Pinene, 3-Cyclohexen-1-ol, 8-Cineole, Alpha Terpinene , Alpha-Humulene, Alpha-Selinene, Alpha-Terpinolene, Alpha-Thujene, Benzene, Beta Fenchyl Alcohol, Beta â€“Selinene, Beta-Elemene, Beta-Myrcene, DI-Limonene, Gamma-Terpinene, Ledene, R(+)- Limonene, and Trans-Caryophyllene. Seeing the content of volatile organic compounds in galam leaf waste, hand soap from galam leaf waste has the potential to inhibit the activity of microorganisms.

We are losing wetlands three times faster than forests. Many efforts have been made to ensure its protection and conservation, including rehabilitation. Rehabilitation measures have been adopted in policies of various jurisdictions. In South Africa, however, these efforts are all over in pieces of different legislation (see Table 1). Paper 1 expressed the extent of the fragmentation through a situational analysis and the effect of such fragmentation. Recommendations were made to bolster rehabilitation provisions for inclusion in South Africaâ€™s envisaged National Joint Wetlands Policy. This paper aimed to address two issues: 1. To learn lessons by focusing on three countriesâ€™ rehabilitation provisions and their method of inclusion; and 2. designing a rehabilitation goal and policy objectives that adequately fits South Africaâ€™s system. The findings are that a SciProfPol objectives are required for wetlands rehabilitation due to the nature of South Africaâ€™s legal system, and the lessons by other jurisdictions may not fully apply but find relevance, along with relevant adjustments.

Peatland is a unique, marginal, and fragile ecosystem. Its utilization must be based on thorough research and planning, and it needs supports from everyone. Yards, fields, and gardens are the forms that the community generally uses to utilize peatlands. This research aims to assess community's activities in the peatlands as their source of living and income. This research was conducted in Indonesia, specifically in the Province of South Kalimantan within an area with the biggest peatland contour. Descriptive data research was analyzed using thematic, socio-economic, and SWOT analysis. Research finding showed that farming is the suitable source of livelihood in the peatlands, besides plantation and other fields. The highest income from non-land activities on the peatlands are from entrepreneurship, physical service, and animal husbandry. People's general livelihood are as farmers whose prior commodity is with bigger average income than the province minimum wage per month. This is expected to describe that income from peatlands can make the ends meet of the community. This can also increase farmer's knowledge in cultivating their lands, the choice of plant type that is suitable with biophysical conditions of the peatlands. To work on the limit of the community's knowledge, activities and solutions from the experts on how to deal with farmer's problems in cultivating peatlands, are needed. Agroforestry technique is very suitable to analyze the source of livelihood. As forms to reserve lands in a farming world, the use of husk charcoal is also suggested. It has abundant benefits. It is often used for soil loosening, even for composting. Farmers make use of it for making compost, bokashi, Takakura, planting media, and seedbed media.
