    East Kalibaru River is one of the thirteen rivers flowing through Jakarta. East Kalibaru River has an important role in development of the region. Considering the increasing activities of people, settlements and number of industries along the East Kalibaru River, it is necessary to calculate contaminants load that discharged into the water body East Kalibaru. This study conducted to determine the point source and domestic waste pollution loads, using parameters of BOD, COD and TSS. The analysis showed that the total pollution loads such are calculated as 43.714 kg/day for BOD, 60.107 kg/day for COD and total 41.529 kg/day for TSS. Total pollution load discharged into river from point source effluent is amounted of 249 kg/day for BOD, 1.505 kg/day for COD and total 411 kg/day for TSS. Effect of domestic waste is very insignificant compared to the effect of point source that went into the river. The result suggest that approach that need to be done to reduce the burden of domestic waste water pollutants is by performing additional production or communal Wastewater Treatment Plant (WWTP) in densely populated areas

    Growing number of Indonesian Batik SMEs has been started since UNESCO announced batik as world heritage from Indonesia in 2009. However, this condition also brings negative impact related to water pollution. Huge variety of dyestuff always has been a challenge in estimating total pollution load from this sector. This study aim to estimate pollution load of some key parameters (BOD5, COD and TSS) of wastewater generated by Batik SMEs in Trusmi cluster. By calculating pollution load factor per unit product (PLU) trough analyzing waste water quality and quantity in every step of batik making process and considering type of fabric (cotton and silk) and type of dyestuff (Naphtol and Indigosol) as variable, it can be concluded that the PLU factor for BOD5 and TSS is associated to the type of fabric, meanwhile COD parameter is associated to the type of dyes. By multiplying the PLU factor with total production capacity from all SMEs in Trusmi cluster, it can be estimated that the total pollution load range in Trusmi area for BOD is at 5,9 – 39,5 ton/year; COD at 112-426 ton/year; and TSS at 4,88-16,3 ton/year

    Penelitian dilakukan di sekitar keramba apung Waduk Cirata (KJA), Purwakarta, Jawa Barat. Penelitian bertujuan untuk mengetahui fluktuasi ketersediaan oksigen terlarut dalam perairan, melalui percampuran massa air yang diambil dari beberapa kedalaman. Konsentrasi DO di lokasi KJA di Waduk Cirata menurun seiring bertambahnya kedalaman dengan kisaran rata-rata adalah 0,3 - 0,5 mg/l (lapisan dasar) hingga 8,0 - 8,4 mg/l (permukaan). Distribusi vertikal oksigen terlarut menggambarkan tipe perairan clinograde. Kedalaman zona eufotik mencapai 3,81 m. Terdapat variasi ketersediaan oksigen terlarut dari pencampuran massa air meromictic dan holomictic. Pada perlakuan 1 (meromictic hingga 12 m) nilai rata-rata DO yaitu 7,00 - 7,41 mg/l. Perlakuan 2 (meromictic hingga 24 m) nilai rata-rata DO 5,28 - 5,48 mg/l. Perlakuan 3 (holomictic hingga 42 m) memiliki nilai rata-rata DO sebesar 2,44 - 2,84 mg/l. Jika terjadi percampuran meromictic hingga kedalaman 12 m dan 24 m maka kegiatan budidaya ikan masih dianggap layak, karena nilai DO >5 mg/l. Akan tetapi, pencampuran holomictic mengakibatkan DO melewati ambang batas, sehingga tidak dapat menopang budidaya perikana

    The research was one part of oil spill contingency plan (OSCP) developed for Delta Mahakam area, where oil & gas exploration and exploitation linked with rich biodiversity supporting coastal community livelihood. Environmental sensitivity analysis for OSCP only do two early stages of OSCP scope, which integrated with the dangers of coastal vulnerability. This analysis mapped environmental component from oil pollution become sensitivity rangking as an effort to support response development strategies and priorities for the coastal resources protection. The aims of this research were (1) to establish environment sensitivity rank and (2) to identify primary factor supporting the environmental sensitivity for OSCP in south Delta Mahakam area. The result of analysis showed environmenal sensitivity was 62.37% (517.52 km), its mean very high sensitivity. Then the high sensitivity criteria was 11.31% (94 km). The criteria of medium sensitivity was 11.92% (99 km). While for low sensitivity and very low sensitivity respectively were 1.78% (15 km) and 12.64% (105 km). Based on Principal Component Analysis (PCA), 36.01% variability was explained by axis of factor 1. The others variability 18.53% and 13.93% were explained by axis of the factor 2 and factor 3. Axis of factor 1 for coastal exposure (EK), oil residence index (OR), coastal type (TP), and biological resources (SH) had a quite large linear combinations coefficient, amounted to 0.94 (EK&OR), 0.83 (TP) and 0.75 (SH). This indicated a very high contribution for environmental sensitivity OSCP level drafting. On axis of factor 2, the linear coeffisien combinations for the resource utilization of port (PL) was 0.83 and settlement (PM) was 0.85. Axis of factor 3 contributed 0.75 and 0.66 on migas platform (PO) and placement of passive fishing gear/catchment area (AT). However, the utilization of coastal resources for PL, PM, PO and AT were on axis of factor 2 and factor 3 had a considerable distance with its SI variable. This possible caused by each variable percentage distribution which the value was very minor ranged 0.001-0.52%, so its not representated coastal resources elements closeness with SI variable in the study area

    Bioplastik adalah plastik yang dapat didegradasi oleh mikroba yang ada di dalam tanah karena adanya kandungan pati di dalamnya. Bioplastik diharapkan merupakan salah satu solusi dari masalah lingkungan yang disebabkan oleh penumpukan sampah kantong plastik belanja yang menjadi beban lingkungan. Secara komersial sudah ada bioplastik yang diproduksi dengan variasi jumlah penambahan pati singkong atau pati jagung, namun kendalanya adalah harga produk masih mahal jika dibandingkan dengan harga kantong plastik konvensional pada umumnya, karena tepung dan pati tersebut masih dibutuhkan di sektor pangan dan energi. Pada penelitian ini bioplastik dibuat dengan menggunakan pati yang diekstraksi dari biji durian yang selama ini merupakan limbah, untuk dicampur dengan biji plastik LDPE pada variasi konsentrasi pati 0% sampai 50%. Sebagai pembanding dipakai pati dari empulur sagu, sehingga karakteristik fisik seperti warna dan sifat mekanik dari bioplastik seperti kekuatan tarik, perpanjangan putus, dan kekerasan dapat dibandingkan. Uji penurunan berat bioplastik dilakukan dengan pemendaman di dalam tanah selama 8 minggu. Hasil uji Anova menunjukkan perlakuan jenis pati dan konsentrasi pati yang ditambahkan tidak beda nyata (p>0,05) terhadap kehilangan berat plastik. Analisis SEM dilakukan untuk membandingkan rongga diantara molekul pati dengan polimer plastik pada perbesaran 2500x yang menyebabkan kekuatan mekanik plastik menjadi berkurang dan rapuh ketika ditarik. Pati biji durian 10% terbukti optimal dapat digunakan sebagai substitusi polimer tanpa penambahan aditif dalam pembuatan bioplastik, dengan karakteristik mekanik yang dapat dibandingkan dengan pati sagu dan pati singkong, namun memiliki laju degradasi yang lebih rendah
