Abstract

This study aimed to determine the Soil Quality Index (SQI) of peatlands where canal blocking was implemented. The research was conducted in two villages in Kubu Raya District, West Kalimantan Province e.g. Madu Sari and Teluk Empening. The sites in Madu Sari were impacted by permanent canal blocking with horticultural crops (M1) and corn (M2), while the sites in Teluk Empening had simple canal blocking with rubber (E1) and horticultural crops (E2). A total of 24 peat soil samples were collected from a depth of 0-20 cm. These samples were analyzed for nineteen physical, chemical, and biological indicators, including peat depth, water-table depth, bulk density, water content, total porosity, permeability, pH, organic carbon, total nitrogen, CN ratio, available phosphorus, exchangeable sodium, exchangeable potassium, exchangeable calcium, exchangeable magnesium, cation exchange capacity, base saturation, ash content, and earthworm. Statistical tests used ANOVA and brown-forsythe to determine the effect of location, as well as tukey test and howell games for further tests. The reduction from 19 to 13 indicators was based on the correlation of the constituent indicators with a value of r>0.5. There are 3 steps  to determine SQI, namely to identification of the minimum data set (MDS), (2) the scoring of the MDS indicators, and (3) the calculation of the SQI value. The SQI values for the sites were 0.64 (good) for M1, 0.56 (moderate) for M2, 0.50 (moderate) for E1, and 0.52 (moderate) for E2, reflecting varying levels of soil quality across the locations. The addition of organic matter from manure has a positive impact on soil quality compared to the application of inorganic fertilisers and intensive tillage.Received: 2024-08-19 Revised: 2024-11-15 Accepted: 2025-08-15 Published: 2025-08-19

Abstract

Provinsi Kalimantan Barat memiliki lahan gambut seluas 1,55 juta ha. Lahan gambut merupakan lahan marjinal yang digunakan untuk budidaya pertanian. Tingkat kesuburan lahan gambut rendah dengan kandungan senyawa organik seperti lignin, selulosa, hemiselulosa, dan tanin. Penelitian ini bertujuan untuk membandingkan konsentrasi senyawa tanin pada lahan gambut yang digunakan untuk budidaya pertanian hortikultura dan semak belukar. Penelitian dilaksanakan dari bulan Mei sampai Juli 2024. Sampel diambil dari 3 plot masing-masing lahan dengan jumlah 4 titik pengambilan. Pengukuran kandungan total tanin dilakukan menggunakan metode Folin-Denis dengan Spektrofotometer Uv-Vis pada panjang gelombang 740 nm. Hasil uji T taraf 5% menunjukkan bahwa konsentrasi senyawa tanin pada lahan budidaya dan lahan semak belukar berbeda tidak nyata. Hal ini diperkirakan karena kedua lahan sama-sama terindikasi telah terdekomposisi. Kesimpulan sementara penelitian bahwa konsentrasi senyawa tanin pada lahan budidaya sayuran dan semak belukar tidak berbeda signifikan.

Abstract

Phenolic compounds are one of the organic materials that can inhibit the decomposition process of peat, are toxic to plants, and difficult to degrade. Degradation of phenolic content can be done enzymatically by phenol-degrading bacteria. The purpose of this study was to compare the content of phenol, tannin, and total colonies of phenol-degrading bacteria on mixed agricultural land at upstream and downstream of the canal blocking built through the hydrological restoration program. The research was conducted from September 2022 to January 2023. Soil samples were taken from two transects (upstream and downstream of canal blocking) using a peat drill.  The samples were analyzed to measure phenol, tannin, and bacterial content.  The results showed insignificant differences in the content of phenol and tannin in peat samples collected from the two transects. The pH, water content, and C-organic content were found in a similar pattern. Total colonies of phenol-degrading bacteria tended to be higher in the transect located upstream compared to the downstream of canal blocking. Keywords: phenol, phenol-degrading bacteria, tannin.INTISARISenyawa fenolik merupakan salah satu bahan organik yang dapat menghambat proses dekomposisi gambut, bersifat racun bagi tanaman, dan sulit terdegradasi.

Abstract

This research aims to compare the methods of bulk density measurements in peat soils. The methods are ring sample, peat auger, and syringe. The research was conducted in peat soils in Pontianak City. The research was carried out from June to December 2023. Peat samples were the surface peat (0-10 cm). The samples were collected from five plots, and five replications. On average, the value of bulk density measured by the ring sample was 0.27 g cm-3, which is significantly different from bulk density values measured by the peat auger and syringe: 0.11 g cm-3 and 0.09 g cm-3, respectively. Bulk densities of peat auger and syringe are statistically indifferent. Soil compaction during sampling causes the ring sample's high bulk density value. Accordingly, carbon stock calculation based on ring sample bulk density is significantly higher than carbon stocks calculated by bulk densities of auger and syringe. The bulk density measurement with a peat auger took longer because a water displacement approach must measure the sample volume. Collecting bulk-density samples with a syringe is the easiest and fastest. The volume of the syringe sample is only 10 cm3, and the sample can be taken until the mineral substratum. The number of sample collected by syringe can be significantly increased at 5 cm sampling interval, or equals to 10 sub-samples per 50 cm peat core. Pearson linear correlations of these three methods are sufficiently strong.

Abstract

Plastic bag waste has the potential to be converted into alternative fuel oil through the pyrolysis method. This study applies the principle of thermal pyrolysis, conducted without oxygen, at the Edelweis Integrated Waste Management Site. The purpose is to analyze the characteristics of fuel oil derived from plastic bag waste based on parameters such as density, viscosity, calorific value, and acid number, as well as to estimate the potential fuel oil yield from plastic bag waste in Pontianak City. The results show that the density, viscosity, and calorific value of the produced fuel oil meet or closely approach standard requirements. However, the acid number measurements exceed the acceptable limits, 0.75 mg KOH/g for gasoline, 0.94 mg KOH/g for kerosene), and 0.50 mg KOH/g for diesel. This is likely due to high levels of chlorine (Cl) and silicon (Si) detected through X-Ray Fluorescence (XRF), which may originate from the plastic materials and red soil used as an adsorbent. Gas Chromatography-Mass Spectrometry (GC-MS) analysis confirms that the fuel oil contains hydrocarbon compounds similar to those found in commercial fuels, though in different proportions. Before the implementation of Circular Letter (CL) Number 43 of 2024, which prohibits businesses from providing plastic bags, the potential fuel oil production is estimated at 1,048,923.59 liters in 2024 and 1,259,375.52 liters in 2045. If this policy is fully implemented, fuel oil production is expected to decrease by approximately 16.52 percent in 2025 and 22.68 percent in 2045, due to the reduced use of plastic bags. This approach could be an effective way to reduce dependence on fossil fuels an estimated by 1 to 1.5 percent in 2025 and 0.8 to 1.7 percent in 2045. Although the results are promising, further testing is necessary to ensure full compliance with fuel standards.

Abstract

Presidential Regulation Number 72 of 2021 on the Acceleration of Stunting Reduction sets a national target of reducing stunting prevalence to 14% by 2024 through integrated programs across government levels, from ministries to villages. In line with this policy, Kubu Raya Regency has shown a decline in stunting rates from 7.9% to 6.8% based on e-PPGBM data, indicating improved implementation of stunting reduction programs. This study aims to analyze the sustainability status of the stunting reduction program in Kubu Raya Regency using the Rapfish (Rapid Appraisal for Fisheries) multidimensional scaling approach. Data were collected from ten Regional Apparatus Organizations (OPDs) through surveys and interviews. The analysis involved six stages: identifying dimension characteristics, scoring on an ordinal scale, determining sustainability status, conducting sustainability checks, performing a sensitivity analysis, and applying a Monte Carlo simulation to account for uncertainty. The results show that the social and economic dimensions are categorized as "quite sustainable" with scores of 60.04 and 51.86, respectively, while the environmental dimension is "less sustainable" with a score of 38.02. Key attributes influencing sustainability include increasing the number of Open Defecation Free (ODF) villages, improving the accuracy of beneficiary data for food assistance, monitoring fortified food products, enhancing nutritional knowledge among pregnant women at risk of chronic energy deficiency, and strengthening village budget planning and cadre development. These findings highlight the need for targeted interventions to improve program sustainability, particularly in the environmental dimension, to ensure long-term success in reducing stunting prevalence.

Abstract

Water quality is a key factor in maintaining ecosystem balance, public health, and the sustainability of the agricultural and industrial sectors. In Sambas District, particularly in the Seminis Sub-watershed, water quality degradation has become a crucial issue, driven by illegal gold mining and the expansion of oil palm plantations, which generate hazardous waste, including mercury, as well as industrial wastewater. This study aims to identify water quality characteristics in the Seminis sub-watershed and analyze the influence of various pollutant sources, particularly from illegal gold mining and oil palm plantations. The research method included surface water sampling at four representative points representing variation in pollutant sources: former mining land, the palm oil mill WWTP outlet, the plantation area, and the settlement. Physical (TSS), chemical (pH, BOD, COD, total nitrogen), and heavy metal (mercury) parameters were analyzed in accordance with national standards and government regulations. The results showed that most water quality parameters remained below the class II quality standards, except for BOD and COD at several points, which exceeded the thresholds due to organic pollutant loads from industrial and agricultural waste.
