Abstract

Penggunaan pupuk NPK pada lahan pertanian secara berlebihan mengakibatkan banyak pupuk tidak terserap sehingga terbawa masuk ke perairan oleh limpasan air permukaan saat hujan dan menyebabkan eutrofikasi. Unsur hara anorganik Nitrogen (N) dan Fosfor (P) menjadi nutrisi bagi alga sehingga menyebabkan tumbuhnya alga yang berlebihan pada perairan atau biasa disebut algae bloom. Penelitian ini bertujuan untuk mengkaji seberapa besar pengaruh jenis dan tinggi lapisan media pada non-vegetated swale dalam menyaring parameter Nitrogen (N) dan Fosfor (P) yang berasal dari larutan pupuk NPK komersial. Metode yang diterapkan adalah dengan menyiramkan aliran air larutan pupuk NPK melalui non-vegetated swale dengan dua ketebalan lapisan yang berbeda. Konsentrasi masuk larutan NPK yaitu 123,77-124,77 mg/l fosfat, 16,54-16,72 mg/l amoniak serta kandungan nitrat dan nitrit yang kecil. Aliran air larutan pupuk NPK sebelum dan sesudah melalui non-vegetated swale diambil sampelnya yang kemudian diuji dengan alat spektrofotometer untuk mengetahui perbedaan kandungan fosfat, nitrat, nitrit dan amonianya. Hasil penelitian menunjukkan bahwa kedua non-vegetated swale memiliki kemampuan menyaring konsentrasi fosfat pada larutan air pupuk NPK yang sangat baik, keduanya mampu mengurangi konsentrasi fosfat hingga 120 mg/l. Hasil pengukuran nitrat dan nitrit menunjukkan kenaikan sekitar 5 mg/l, sedangkan kandungan amoniak turun sekitar 16 mg/l. Hal ini menunjukkan terjadinya proses nitrifikasi dan menunjukkan bahwa kedua non-vegetated swale pada penelitian ini memiliki kemampuan penyaringan N yang belum optimal.

Abstract

Surface mining, including tin mining, is the most common mining practice in Indonesia. The existence of mining ore or minerals close to the surface soil is the reason for carrying out this mining method. The process of mining surface resulted in the change of land landscape, which may cause soil erosion and even flood. It has caused various ecological and environmental problems, including soil degradation. This study describes soil physio-chemical properties impacted by surface tin mining in Bangka, Indonesia. Soils were collected from three different land use in natural forest, agroforestry, and post tin mining area in Bangka Regency, Province of Bangka Belitung Island. Five-spot soils were sampled from each site. Each site had three replication of the sampling area. The plot size for each site is about 200-500 m2. Soil texture, pH, total N, available P, exchangeable K, organic carbon, C/N ratio, CEC, Al3+, and H+ were analyzed. The results showed that mining decreased organic carbon, total N, available P, exchangeable K, and CEC. Mining changed the soil texture to be dominated by quartz sand. These results indicate that mining significantly deleterious soil fertility, therefore, potential as a limiting factor for plant growth, which could be a hamper for restoration efforts of post tin mining areas.

Abstract

Tin mining produced massive tailings which dispersed across the land in the post-tin mining area, transforming the landscape into a hilly or basin landscape. The dominated white silica sand in this area is prone to erosion from water and wind, resulting in soil nutrition deficiency, meanwhile, heavy metal levels were found to be elevated. This condition makes it difficult for organisms to live in such a degraded post-tin mining area. Phosphate solubilizing microorganisms (PSM) contribute to phosphate availability by dissolving both fertilizers and bounded P in soil. This study aimed to select indigenous PSM collected from post-tin mining areas. Zea mays spp., the tested plant, was grown in sterilized sand to avoid the possible nutrient content, particularly phosphate, in the soil. Rock phosphate Granufos (containing 20% P2O5) was applied in sterilized sand (v: v= 1:100) as the source of limited and insoluble P. The 17 indigenous PSM were tested by inoculating them into Zea mays spp. growing in sterilized sand. Non-inoculated Zea mays spp. were prepared as well as control. Inoculation of 17 indigenous PSM significantly had higher soil available phosphor in comparison to control. Two PSM of P7 and P15 significantly had higher shoot concentrations among treatments. The isolate of P5 had the highest shoot dry weight among treatments. Overall, all PSM inoculations improved growth performance due to increased soil available P and improved shoot P uptake. These findings suggest that indigenous PSM potentially fills nutrient deficiencies, particularly P as a macronutrient needed to rehabilitate degraded post-tin mining areas.

Abstract

Abstract Inorganic nutrient types such as nitrates (N), phosphates (P), and silicates (Si) are widely absorbed by phytoplankton. All three types of nutrients are very important for their growth. Through the process of photosynthesis, the three nutrients are converted into food reserves in the form of organic compounds such as carbohydrates. The results of the photosynthesis process are used by other organisms in the tropics to grow. The purpose of this study was to analyze the distribution of inorganic nutrients of type N (nitrate), P (phosphate), and Si (silicate) for phytoplankton life. The research was carried out from June to October 2021 at three stations in the coastal waters of Tompotana, Tanakeke Islands District, Takalar Regency, South Sulawesi. At the three stations, water sampling was carried out for the purposes of phytoplankton identification and measurement of physico-chemical parameters of the waters. Activities carried out in the laboratory such as phytoplankton identification, nitrate, phosphate and silicate measurements. Based on the analysis of variance, nitrate and phosphate concentrations were not significantly different (p > 0.05) between stations, on the contrary silicate concentrations actually differed significantly (p < 0.05). N, P, and Si nutrients can still be absorbed and used by phytoplankton to grow even though they are not optimal. A total of 4 classes and 24 types of phytoplankton were identified. The four classes in question are Bacillariophyceae, Dinophyceae, Cyanophyceae, and Coscinodiscophyceae. From the results of the Pearsons correlation analysis, only nitrates had a significant effect on phytoplankton abundance in Tompotana waters (p<0.05).

Abstract

Banjar river in West Banjar Village, Gapura District, Sumenep Regency, is used by the local community for bathing, washing and toilet activities. This activity was carried out directly into the river, causing river water pollution. In addition to the bathing and washing activities in the river, there was tofu wastewater deliberately dumped directly into the Banjar River. Pollution load increased in river. Under these conditions, research is needed to determine the amount of pollution in the Banjar River and determine the status of water quality to describe the level of water pollution. Quantitative descriptive method is the approach used in this test using the paraThe quantitativ OD,BOD, COD, pH, TSS. Water quality standarts is guided by PP RI Number 22 of 2021 while the regulations for determining water quality status using the storet method are guided by KepMen LH No.115 of 2003. The Banjar River is divided into 4 segments based on pollutant sources and the characteristics of the Banjar river. Segment determination characteristics include kilometers from downstream, length and geographic coordinates. All water quality parameters were analyzed for ,trends in concentration changes and correlations between parameters. The test results show that based on the COD, TSS and pH parameters in the Banjar river meet the quality standards while the ,DO and BOD parameters for each sampling point produce values ​​that exceed the quality standards. Water quality status based on the storet method at points A, B, D, and E scores between -8 until -10 with the status of "Slightly Polluted" while point C has a value of -12 with the status of "Moderately Polluted".
