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. Degradasi kandungan fenolik dapat dilakukan secara enzimatik oleh bakteri pendegradasi fenol. Tujuan penelitian ini adalah membandingkan kandungan fenol, tanin, dan total koloni bakteri pendegradasi fenol pada lahan pertanian campuran hulu dan hilir sekat kanal yang dibangun melalui program restorasi hidrologi. Penelitian dilaksanakan pada bulan September 2022 hingga Januari 2023. Sampel tanah diambil pada dua transek (hulu dan hilir sekat kanal) dengan menggunakan alat bor gambut. Sampel dianalisis untuk mengukur kandungan fenol, tanin, dan bakteri. Hasil penelitian menunjukkan adanya perbedaan yang tidak signifikan kandungan fenol dan tanin pada sampel gambut yang dikumpulkan dari kedua transek. PH, kadar air, dan kandungan C-organik ditemukan dalam pola yang sama. Total koloni bakteri pendegradasi fenol cenderung lebih tinggi pada transek yang terletak di bagian hulu dibandingkan di bagian hilir sekat saluran. Kata kunci: fenol, bakteri pendegradasi fenol, tanin

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

Diarrhea in East Mempawah has increased in the last four years. Data from 2017 to 2021 shows an increase of 76% in diarrhea cases. This study aims to determine the relationship between using clean water, healthy latrines, washing hands,and knowledge on preventing diarrhea in six villages and two sub-districts in East Mempawah. This study was a case-control study that observed 43 cases and 43 controls aged 1-4 years old children with research instruments in the form of questionnaires. Data analysis used the chi-square test. The results showed that clean water sources were not related to the incidence of diarrhea with a p-value = 0.065, OR = 2.376 (95% CI=0.9361-6.0309). Defecation behavior was not related to the incidence of diarrhea with p-value=0.88, OR=1.222 (95% CI=0.459-3.255). The habit of handwashing was the incidence of diarrhea with a p-value = 0.023, OR = 5.161 (95% CI=1.339-19.895). Knowledge was related to the incidence of diarrhea with p-value = 0.003, OR=2.877 (95% CI=1.194-6.934).This study concludes that there is a relationship between handwashing and knowledge of the incidence of diarrhea.The handwashing habit is related to the incidence of diarrhea due to low awareness and willingness to do it. The Health Service needs to hold joint cross-sector and cross-program socialization activities about the importance of handwashing,as well as provide handwashing facilities in public places so that people can easily access them.

Abstract

Pabrik kelapa sawit menghasilkan limbah cair yang berpotensi mencemari lingkungan apabila tidak dikelola dengan baik. Instalasi Pengolahan Air Limbah (IPAL) pada PT. X di Kecamatan Sintang, Kabupaten Sintang, Provinsi Kalimantan Barat dirancang untuk menurunkan kadar pencemar utama, seperti Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Total Suspended Solids (TSS), pH, minyak dan lemak, serta nitrogen total. Penelitian ini bertujuan untuk mengevaluasi tingkat efisiensi pengolahan limbah cair pada unit IPAL, khususnya kolam anaerobik dan aerobik dengan menganalisis penurunan parameter COD, BOD, TSS, pH, minyak dan lemak, serta nitrogen total. Metode yang digunakan adalah analisis deskriptif kuantitatif berdasarkan hasil uji laboratorium terhadap sampel yang diambil dari kedua kolam tersebut. Hasil penelitian menunjukkan bahwa sistem IPAL mampu menurunkan COD sebesar 90,11%, minyak dan lemak sebesar 88,89%, BOD sebesar 86,59%, dan TSS sebesar 76,53%, yang dikategorikan sebagai sangat efisien hingga efisien. Namun, pengolahan terhadap parameter nitrogen total belum menunjukkan hasil yang optimal, dengan tidak efisiensi atau kurang <20%. Ketidakefektifan ini disebabkan oleh faktor teknis, seperti rusaknya sebagian aerator dan pendangkalan kolam akibat akumulasi lumpur, yang berdampak pada waktu tinggal limbah yang tidak mencukupi. Oleh karena itu, perbaikan sistem aerasi dan pemeliharaan kolam secara berkala diperlukan guna meningkatkan efektivitas pengolahan secara menyeluruh.

Abstract

Tidal land has great potential for agricultural development, but the characteristics of its soil physical properties can be affected by seawater fluctuations. This study aims to examine the physical properties of soil in two types of land use, namely mixed gardens and tidal rice fields in Wajok Hilir Village, Mempawah Regency. The parameters analyzed include field capacity water content, bulk density, porosity, and soil texture. The sampling method was carried out in full at five replication points in each land, and the analysis was carried out in the laboratory of the Faculty of Agriculture, Tanjungpura University. The results showed that the highest field capacity water content was found in tidal rice fields at 199.73%, while mixed gardens only 76.98%. The bulk density of paddy soil was lower (0.4 g/cm³) than mixed gardens (0.72 g/cm³), indicating that the paddy soil was looser. The porosity of paddy soil was also higher (78%) than mixed gardens (65.27%). Both types of land have the same soil texture, namely silt loam, which supports the ability to store water and nutrients. These findings indicate that water management and organic matter content greatly influence the physical properties of soil in supporting land productivity.
