Abstract

Plastic has a fairly wide distribution in human life. The use of microplastics is very difficult to avoid because it has reduced various human activities. The use of plastics on a large and wide scale raises a problem for the environment and ecosytem through the degradation of plastics into microplastics. Microplastics have the potential to pose a threat to the environment and organisms, especially in water areas. Their small size allows microplastics to be ingested by zooplankton up to a higher trophic level. Damas Beach is one of the marine tourism destinations in the Prigi bay area with a potential fishery sector in East Java. The high activity of tourism and fishing causes Damas beach to be potentially polluted by microplastics. This study aims to determine the type of plastic polymer in the digestive tract of lisong tuna obtained in the Damas beach area, Prigi Bay, Treanggalek Regency, East Java. This study used a purposive sampling method with two repetitions. Types of microplastic polymers were analyzed using FTIR. The results of the analysis showed that the types of plastic polymers found in the digestive tract of lisong tuna include High Density Polyethylene (HDPE), Polyvinyl chloride (PVC), nylon (polyamide, Polyethylene Terephthalate (PET), Polypropylene (PP), and Polystyrene (PS).

Abstract

Plastics can be degraded into microplastics and easily to dispersed in waters, including reservoirs as water damming locations. Lahor Reservoir is known to be used as a location for aquaculture, one of which is nile tilapia (Oreochromis niloticus) and is fed by the Lekso river, Lahor river, and Dewi river. This certainly increases the potential for microplastic contamination and has a negative impact on aquatic biota and humans. The purpose of this study was to determine the potential for microplastic contamination in the digestive tract of nile tilapia in Lahor Reservoir, Malang Regency, East Java. The study was conducted at 4 sampling stations including Lekso river inlet, Lahor river inlet and Dewi river, Residential area of Karangkates village, and Lahor Tourism Park. 5 Fishes samples were taken at each station and the repetition process was carried out 3 times. Sample preparation with 20 ml of 30% HzO2 solution and 20 ml of 10% KOH. Identification types and abundance of microplastics was carried out with a 40× magnification stereo microscope. The results showed the discovery of several types of microplastics which is fiber, filament, fragment, and film and the highest total abundance value of microplastics was found in the Lahor river inlet and Dewi river at 6.47 particles / individual.

Abstract

The purpose of the paper is to investigate role of the financial performance, ownership structure and number of syari'a supervisory board of Islamic banks in Indonesia on the sustainability of corporate social responsibilities (CSR) disclosure. Ownership structure and number of syari'a supervisory board of Islamic banks as proxy of implementation good corporate governance (GCG). There are seven (7) fully fledge Islamic banks in Indonesia. This study uses logic regression to test empirically whether the CSR is highly influenced by the factors identified earlier. Evidence was found that size, ROA and leverage do not have significant role in corporate social responsibilities (CSR) disclosure. Specifically, the results infer the fact that the CSR disclosures are significant and positively associated to bank size and ownership structure only. The result of the study has confirms the hypothesis that bank size and ROA has positive associated with CSR disclosure. This suggested that large and profitable banks have more resources to devote to social activities. Leverage negatively influences the disclosure of CSR. Thus, lowly leveraged banks will tend to make larger donations than highly leveraged banks. Ownership structure and number of syari'a supervisory board of Islamic banks have positive associated to CSR disclosure. These results also confirm the predictions that good corporate governance mechanism lead to the greater monitoring and thereby greater CSR disclosure.

Abstract

Rivers are a water source that has many roles in people's lives and is inhabited by many organisms. The quality of water can be seen from the number of organisms that live in that water. Organisms that can be used as biological indicators are macrozoobenthos. Macrozoobenthos are organisms whose movement characteristics tend to be limited and where they live permanently. The way to find indications of pollution in a river is to calculate the diversity of macrozoobenthos populations in the riverbed. The purpose of this study was to determine the diversity of macrozoobenthos in the Sumber Ngenep River, Karangploso District, Malang Regency. This research is quantitative research with an exploratory method. Sampling was carried out at 3 stations with 3 repetitions at each station. Identification using 3 literature and data analysis using the Shannon-Wiener Diversity Index (H') and Simpson Dominance Index (D). The research results obtained 10 macrozoobenthos genera. The diversity index value of station 1 (1.389), station 2 (1.638), station 3 (1.343). Dominance index value of station 1 (0.286), station 2 (0.262), station 3 (0.309).

Abstract

Pemanfaatan kotoran sapi, pakan ternak dan sekam padi sebagai kompos memerlukan waktu yang sangat lama, sehingga diperlukan bahan pembantu seperti cacing tanah dengan metode vermikomposting. Penelitian ini bertujuan untuk menganalisis pengaruh variasi bahan baku vermikomposting terhadap parameter kimia kompos (rasio C/N, P dan K) serta membandingkan kualitasnya dengan standar kualitas kompos SNI 19-7030-2004 dan Permentan No. 70 Tahun 2011. Metode yang digunakan adalah eksperimen dengan dua variasi perlakuan kotoran sapi : sisa pakan sapi : sekam padi (A 40% : 45% : 15% dan B 50% : 35% : 15%) serta penambahan 0,4 kg cacing tanah (Lumbricus rubellus). Hasil penelitian menunjukkan bahwa variasi bahan baku berupa penambahan kotoran sapi hanya berpengaruh signifikan (p < 0,005) terhadap peningkatan nilai Kalium dan tidak berpengaruh signifikan terhadap nilai rasio C/N dan Fosfor. Nilai parameter kimia terbaik yang memenuhi standar kualitas kompos berdasarkan SNI 19-7030-2004 adalah variasi kompos B dengan nilai Rasio C/N 16, Fosfor 1,23 % dan Kalium 0,76%. Nilai parameter tersebut telah sesuai dengan standar SNI 19-7030-2004, namun belum memenuhi standar Permentan No 70 Tahun 2011.

Abstract

Jumlah kendaraan di Indonesia meningkat setiap tahunnya sehingga menuntut adanya jasa pencucian kendaraan, peningkatan tersebut dapat menurunkan kualitas lingkungan. Limbah cair bekas pencucian kendaraan di Kramatwatu Kabupaten Serang dapat menimbulkan pencemaran limbah yang melebihi standar baku mutu air limbah yaitu pH dan methylene blue active substance (MBAS). Tujuan penelitian ini untuk mengetahui efektivitas serta efisiensi dari media filter Fly ash dan PAC untuk menurunkan kadar pH dan MBAS di dalam limbah pencucian kendaraan. Metode yang digunakan yaitu dengan cara filtrasi dengan variasi ketebalan media 750 g, 1000 g dan 1500 g. Hasil filtrasi MBAS menunjukkan bahwa nilai efisiensi rata-rata pada media filter fly ash 79,33 mg/L, 83 mg/L, dan 75,23 mg/L, sedangkan PAC 125,07 mg/L, 92,07 mg/L, dan 56,57 mg/L, dengan efektivitas rata-rata yang dihasilkan masing masing media yaitu fly ash 42,43%, 37,77%, dan 45,40%, sedangkan efektivitas rata-rata PAC 9,24%, 33,19% dan 58,95%, dan pH menurun dari 10,01 menjadi 8,25 untuk fly ash sedangkan 7,72 untuk PAC.
