Abstract

Investment development for oil palm plantation in Indonesia was increasing and it clear away into peat land area. Land clearing activities without considering peat ecological function may have impact on environmental degradation. The objective of this research was to study development potential of oil palm plantation at peat land by using land evaluation approach. The field survey method was observation scale and land suitability assessment was based on FAO standard with adjustment. Assessment results showed that land had peat thickness higher than 3 m covering 28% of total area so that it can be opened for oil palm plantation. The main constraint factors for the clearing of feasible area were soil reaction, flooding condition and nutrients status. These parameters could be potentially improved. However, final assessment of land showed that it was classified as less feasible (S2) due to relatively high investment.  Cultivation can only be conducted with provision of drainage facility. Caution should be taken in designing open channel in order to prevent excessive water drainage. Therefore, hydrologic analysis can be based on 5 years return period only. Computer simulation of DRAINMOD was applied to determine the operational effect of control structures in elevating of water table during dry season. Simulation results showed that during the opening operation of open channel without control structures at dry season, water table was dropped up to 90 cm below soil surface. Water retention effort in tertiary channel at 70 cm level could elevated water up to 30-40 cm below soil surface. The key success for oil palm plantation development at peat land was highly depended on availability of control structure at tertiary channel. Flap water gate type from fibre material was very suitable for field application. Retention system by using soil sack or stoplog water gate could be implemented at initial stage in order to economize the cost.

Abstract

Sebagian besar produktivitas pertanian di lahan pasang surut masih rendah. Hal ini disebabkan oleh permasalahan utama pada tingkat kesuburan dan kecukupan airnya. Penelitian ini bertujuan untuk menilai status kesuburan tanah dan menyusun rekomendasi perbaikan kualitas lahan pada berbagai kelas hidrotopografi di lahan rawa pasang surut. Penelitian dilaksanakan pada bulan Agustus-Oktober 2022 pada pertanaman padi di areal lahan reklamasi rawa pasang surut desa Sri Mulyo, Sri Katon dan Sido Harjo Kecamatan Air Salek, Kabupaten Banyuasin, Sumatera Selatan. Metode yang digunakan adalah survei dengan tingkat semi detail, area pengambilan sampel meliputi lahan kelas hidrotopografi A (basah, potensi irigasi pasang surut pada musim hujan dan musim kemarau), B (irigasi pasang surut hanya untuk musim hujan), dan C (kering, tadah hujan). Data lapangan meliputi karakteristik sifat fisik tanah, kedalaman air tanah dan lapisan pirit. Analisis tanah dilakukan di Laboratorium Kimia, Biologi dan Kesuburan Tanah serta Laboratorium Fisika dan Konservasi Tanah, Fakultas Pertanian, Universitas Sriwijaya meliputi analisis tekstur, bobot isi tanah, pH, C-organik, N-total, P-tersedia dan K-dd. Hasil penelitian menunjukkan bahwa status kesuburan tanah tergolong sedang dan tidak terdapat pengaruh yang nyata antara kelas hidrotopografi dengan status kesuburan tanah. Namun, kedalaman pirit di lahan tipe C lebih rendah daripada di tipe A dan B. Kondisi ini mengharuskan pengelolaan lahan yang lebih hati-hati di tipe C untuk tetap menjaga kedalaman air tanah berada di zona akar agar terhindar dari oksidasi pirit serta pengelolaan air untuk meningkatkan retensi air hujan dan menjaga kedalaman air tanah tetap berada di atas lapisan pirit. Selain itu, operasi pintu di saluran tersier disarankan untuk lebih banyak ditutup sehingga air di saluran tidak hilang selama budidaya tanaman padi dilakukan. Pemberian bahan amelioran seperti sekam padi juga sangat dianjurkan untuk memperbaiki kualitas tanah pada lokasi tersebut.

Abstract

Pathogenic microorganisms present in river water pollution are a serious health risk. Escherichia coli is a pathogen commonly found in water. Escherichia coli is an indicator of water contaminated with feces. These pathogens have an impact on human health. Aur River is one of the tidal rivers in Palembang City. From the observations, many people dispose of domestic waste into river bodies, so the river is at risk of being polluted by pathogenic microorganisms. When it recedes, the water looks pitch black, and when it is high, many people bathe, brush their teeth, and wash their clothes in this river. Thus, this study aimed to monitor water quality, including total coliform, of the Aur River Palembang City. The results of this monitoring can be used as the basis for making a policy and strategy to control the quality of this river water. This study was carried out on the Aur River, which is 2.5 km long. Measurements were made at three stations, namely at the upstream, middle, and downstream. Based on measurements of the pH, BOD, COD, DO, and total coliform concentrations, it is concluded that the Aur River has been polluted because the BOD, COD, DO, and total coliform were above the quality standards. The pH is still at the quality standard.

Abstract

Soils that are acid sulfuric have low productivity, because the physical and biological conditions of this land are characterized by high acidity. Based on the problem of acid sulphate soil, micro remediation research is carried out to fulfill objectives such as the formation of good and sustainable cultivation land. Acid sulphate soil was taken from at Mesuji Ogan Komering Ilir in January 2023. The method in this study was field observation by taking samples using a belgi drill at several points of the land. The study used a pot with a size of 12 cm x 15 cm which was washed 5 times to remove the acid content in the soil. The pot contains 40% soil, 40% sugarcane husk and 20% rice husk biochar. The object used in this study is the ginger plant. High levels of soil acidity can trigger the dissolution of toxic elements and increase the cause of nutrient deficiencies. Adsorption of complexes in the soil will offer sufficient nutrients for plant development if the soil is rich in soluble bases. Conversely, the soil will tend toward acid if Al and H dominate the adsorption complex. The results of this study can be concluded that micro remediation using sugarcane pulp and biochar has a very real impact. The use of sugarcane bag and biochar in this study helped reduce the initial Al of 9.97 Cmol+/kg to 1.65 Cmol+/kg in the soil and lowered the soil acidity level in the initial soil with a pH of 3.26 to a soil pH of 4.94.

Abstract

Tidal lowland is a marginal land characterized by low pH, deficient  nutrients, and salinity. Despite these challenges, El Niño phenomenon often occurs during the second planting season, resulting in long droughts. However, tidal lowland must be used for cultivation due to the need for rice and the land should be treated accurately. Therefore, this research aimed to address the issues by improving the efficiency of rice cultivation on tidal lowland through precision farming practices. A survey and land analysis were conducted in tidal lowland of B typology in Delta Saleh, Indonesia, from March 2023 to June 2023. In this precision farming practice, water management was highly prioritized, starting from tertiary channels such as optimizing sluice gate operations and monitoring water levels in channels and groundwater. Additionally, pH, CEC, and C-Organic analysis were also carried out in rice cultivation, as showed by the  equation Y = 0.15 - 0.001 pH + 0.000 CEC + 0.000 C-Organic. The highest production yield was 2.05 tons/ha in P5, with the SEW-10 value during cultivation activities being 778 cm and the number of days above -10 reaching 84. Moreover, the efficiency of rice cultivation was improved through precision agricultural practices by using valve sluices and levees.

Abstract

Peat formation is the main key to carbon sequestration in the Peat Swamp Forest (PSF). The research aims to analyze alternative possibilities for peat formation based on the available soil nutrients and dried biomass. In a complete randomized block design, a factorial trial was applied using two treatment combinations in three blocks: factor A (sampling plots, land cover) and Factor B (dried biomass). Data were analyzed using two-way ANOVA and Tukey Honestly Significant Difference test at a significance level of 5%. A high supply of dried below-ground biomass did not follow the production of rooting litter at high soil nutrients. Most of the biomass was transported upwards into above-ground biomass. All land covers produced above-ground biomass which had the potential to form peat with significant differences for all parameters studied. The potential for peat formation was highly dependent on the various types of land covers (e.g. peat forest), environmental factors, the composition of the seed bank, and the species ability to compete. Restoration actions (revegetation, rewetting, and revitalization) aim to stimulate the development of peat-forming species. The research benefits are expected to enrich PSF's ecological restoration thinking so that PSF can be restored and returned to near its initial condition.

Abstract

Flooding is one of the causes of environmental damage worldwide. Several things that can affect flooding in urban areas, Palembang experiences periodic flooding problems, especially every rainy season. The data in this article consists of primary data obtained from location surveys in retention ponds, including: documentation, topography, depth of retention ponds and secondary data from related agencies, including: location maps, climatology, regional topography. Palembang City has varying levels of flood vulnerability: high (Jakabaring, Kertapati, Plaju, and Seberang Ulu), medium (Ilir Barat and Sukarame), and low (Alang-Alang Lebar). Lowland areas with poor drainage systems require more attention. Retention ponds play an important role in managing rainwater runoff, such as the Jakabaring Sports Hall (200,000 m²), Ogan Permai Indah (22,217 m²), and Brimob Demang Lebar Daun (30,000 m²). The city's topography, which is mostly flat and low, especially around the Musi River, further increases the risk of flooding.

Abstract

Abstract Pelands play a crucial role in human life as they are significant carbon (CO2) storage systems. The El Nino phenomenon impacts peatlands by causing them to dry out and become highly to fire. For the surrounding communities, peatlands can be utilized for income-generating activities such as gardening. However, due to a lack of education and financial resources for land development, the community often resorts to burning, which they perceive as an easier and more efficient method. In reality, the consequences of forest and peatland fires are substantial, affecting social, economic, and health aspects. Restoring burned peatlands requires a long time and several efforts; restoration cannot be accomplished in just a few years. This research assesses the impact of forest and land fires. Based on data obtained using Landsat-8 imagery from 2015, 2019, and 2023, significant changes in land cover have occurred. However, forest and land fires in other land use areas, which are community lands, continue to show dynamics during each El Nino season. Integration among various stakeholders is essential to educate the community on the importance of preserving peatlands.

Abstract

Tidal marshlands have significant potential for agriculture, despite being affected by fluctuations in sea and river water. This study aims to analyze changes in vegetation density on agricultural land in Sri Mulyo Village, Air Saleh Sub-district, Banyuasin Regency, South Sumatra, using Sentinel-2A satellite imagery and the NDVI (Normalized Difference Vegetation Index) method. Observations were conducted in February, during the wet season, recorded a rainfall of 381 mm, while August, in the dry season, recorded a rainfall of 17 mm, based on data from the BMKG Climatology Station in Palembang for the year 2024, focusing on land cover changes in vegetation density under two different seasonal conditions. The analysis showed a decrease in the area with high vegetation density in August (56.01%) compared to February (63.97%), due to low rainfall and decreased soil moisture in the dry season. In contrast, the medium vegetation category increased in August. These findings suggest that seasonal variations significantly affect vegetation cover and productivity of tidal marshlands. as a consequence, during the dry season, increased drainability and reduced soil moisture contribute to a decline in  vegetation density, with the percentage of areas categorized as “High Greenness” decreasing to 56.01% and those categorized as “Moderate Greenness” increasing to 36.17%. These findings emphasize the crucial role of rainfall in sustaining vegetation in tidal marshlands, particularly under varying seasonal conditions.

Abstract

Palembang City frequently experienced flooding during the rainy season, necessitating effective urban water management strategies such as the development of retention ponds. This study employed several analytical methods, including erosion level assessment using the Universal Soil Loss Equation (USLE), sediment yield estimation through bedload traps and suspended sediment samplers, dead storage volume analysis by comparing storage capacities before and after sedimentation, sediment thickness rate calculation based on total erosion per unit area, and retention pond lifespan prediction using dead storage capacity, sediment discharge, and sediment specific weight. The results indicated extremely severe erosion rates ranging from 3,241 to 4,593 t/ha/year (>480 t/ha/year) and very high sediment yields between 4,368 and 7,018.5 t/year (>500 t/year). Sediment accumulation reduced storage efficiency, with dead storage volume reaching 44–61.11%. Siti Khadijah, RC reservoir, Talang Aman I, and IBA retention ponds were classified as having very large dead storage volumes, while Talang Aman II retention pond was in a large category. Sediment thickness rates ranged from 227.2 to 397.9 mm/year (>50 mm/year), indicating a very high sedimentation rate. Consequently, the estimated operational lifespan of the ponds was very short, between 1.86 and 6.36 years (<10 years). In conclusion, the retention pond areas in Palembang exhibited critical erosion and sedimentation issues, resulting in high sediment accumulation, reduced storage capacity, and significantly shortened pond lifespans. These findings highlight the urgent need for sustainable sediment management and maintenance strategies to enhance the effectiveness and longevity of urban retention ponds.
