ABSTRAK: Kerusakan terumbu karang merupakan permasalahan serius di laut saat ini. Kerusakan tersebut disebabkan oleh beberapa faktor salah satunya penggunaan pestisida. Salah satu jenis pestisida yang digunakan para petani yaitu pestisida triazofos. Penggunaan pestisida triazofos di sektor pertanian akan meninggalkan residu dan terbawa ke perairan melalui sungai dan saluran air. Residu pestisida triazofos diduga dapat menyebabkan kerusakan ekosistem terumbu karang. Tujuan dari penelitian yaitu untuk mengetahui potensi resistensi karang Porites sp. dan Galaxea sp. terhadap pestisida triazofos dari Perairan Pulau Panjang, Jepara. Metode yang digunakan untuk pengambilan sampel adalah purposive sampling method, untuk memperoleh isolat bakteri yang berasosiasi dengan karang Porites sp. dan Galaxea sp., dan metode experimental laboratoris untuk uji resistensi isolat bakteri. Kurva regresi larutan standar dengan persamaan y = 0,0057x + 0,1088 dipakai untuk menentukan konsentrasi pestisida triazofos. Nilai R² menunjukkan angka 0,8694 yang berarti secara umum data yang dihasilkan mempunyai validasi data yang baik. Konsentrasi pestisida triazofos digunakan dalam uji degradasi oleh bakteri sebesar 50 ppm. Nilai absorbansi yang dihasilkan sebanyak 0,5285. Hasil uji menunjukkan seluruh isolat yang digunakan bersifat resisten terhadap pestisida triazofos yaitu PPP 11, PPP 9, GPP 6, PPP 1, GPP 7, GPP 4. Isolat PPP 11 memiliki persen degradasi tertinggi sebanyak 99,67%, GPP 4 memiliki persen degradasi terenddah sebanyak 34,34%. Disimpulkan bahwa isolat bakteri asosiasi karang Porites sp. dan Galaxea sp. memiliki resistnesi terhadap pestisida triazofos. ABSTRACT: Damage to coral reefs is a serious problem at sea at this time. The damage is caused by several factors, one of which is the use of pesticides. One type of pesticide used by farmers is the triazophos pesticide. The use of triazophos pesticides in the agricultural sector will leave residues and be carried into the waters through rivers and waterways. Triazophos pesticide residues are thought to cause damage to coral reef ecosystems. The purpose of this study is to determine the potential of coral resistance Porites sp. and Galaxea sp. against triazofos pesticides from Panjang Island waters, Jepara. The method used for sampling is purposive sampling method, to obtain bacterial isolates associated with Porites sp. and Galaxea sp., and spectrophotometric methods for testing bacterial isolate resistance. Standard solution regression curves with the equation y = 0.0057x+ 0.1088 are used to determine the concentration of the triazophos pesticide. R² value indicates the number 0.8694 which means that in general the data generated has good data validation. The concentration of the triazofos pesticide used in the bacterial degradation test was 50 ppm. The absorbance value produced was 0.5285. The test results showed that all isolates used were resistant to triazophos pesticides namely PPP 11, PPP 9, GPP 6, PPP 1, GPP 7, GPP 4. PPP 11 isolates had the highest degradation percentages of 99.67%, GPP 4 had the lowest degradation percentages 34.34%. It was concluded that the bacterial isolates of Porites sp. and Galaxea sp. has triazofos pesticide resistance.

The Impact

Eleven billion microplastic particles are entangled in coral reef ecosystems in the Asia - Pacific Region. The presence of microplastics in coral reef ecosystems in Indonesia, especially in the Karimunjawa Marine National Park, was found as many as 22.7 and 12.8 particles / kilogram samples in two locations. The presence of microplastics in coral reef ecosystems allows threats to the health of coral reefs. Therefore, the importance of this study is to complement the data on the distribution of microplastics in the Karimunjawa Marine National Park as an initial step for conservation and mitigation of the impact of plastic/ microplastic pollution. Sampling using purposive sampling method. Sediment collection using SCUBA set and sediment grab at a depth of 3 - 5 meters. ± 1000 g of sediment was taken and stored in double zip lock plastic. The samples were then analyzed by microplastics in the Tropical Marine Biotechnology Laboratory, FPIK UNDIP. The results showed that the greatest abundance of microplastics was in the Karang Tengah area with the number of microplastics 96 particles / kilogram, and the farthest in the Ujung Gelam and Lego was 11 particles / kilogram. Research shows that the abundance of microplastics in areas with human activities such as tourism, ports, and boat routes has a high abundance compared to conservation areas or areas with little human activity. It is hoped that the available data from this type of research will be able to produce decisions on conservation measures in Karimunjawa Marine National Park.  Sebelas miliar partikel mikroplastik terjerat pada ekosistem terumbu karang di Kawasan Asia – Pasifik. Keberadaan mikroplastik pada ekosistem terumbu karang di Indonesia, khususnya di Taman Nasional Laut Karimunjawa, ditemukan sebanyak 22,7 dan 12,8  partikel/kilogram sampel di dua lokasi. Keberadaan mikroplastik di ekosistem terumbu karang memungkinkan adanya ancaman terhadap kesehatan terumbu karang. Oleh karena itu pentingnya penelitian ini untuk melengkapi data sebaran mikroplastik di Kawasan Taman Nasional Laut Karimunjawa sebagai langkah awal konservasi dan mitigasi dari dampak polusi plastik/mikroplastik. Pengambilan sampel menggunakan metode purposive sampling. Pengambilan sedimen menggunakan SCUBA set dan sediment grab pada kedalaman 3 – 5 meter. Sedimen diambil ± 1000 gr dan disimpan dalam plastik double zip lock. Sampel kemudian dianalisis mikroplastik di laboratorium Tropical Marine Biotechnology, FPIK UNDIP. Hasil menunjukkan bahwa kelimpahan mikroplastik terbesar pada daerah karang tengah dengan jumlah mikroplastik 96 partikel/kilogram, dan terkecil pada perairan ujung gelam dan lego yaitu sebanyak 11 partikel/kilogram. Penelitian menunjukkan bahwa kelimpahan mikroplastik didaerah dengan aktivitas manusia seperti pariwisata, pelabuhan, dan jalur kapal memiliki kelimpahan tinggi dibanding dengan daerah konservasi atau daerah dengan aktivitas manusia yang kecil. diharapkan dengan data yang tersedia dari penelitian sejenis ini, mampu menghasilkan keputusan terhadap langkah konservasi di Taman Nasional Laut Karimunjawa.

ABSTRACT This study examines the influence of audit tenure and auditor reputation on audit quality with operational complexity as a moderating variable. The Enron case involving Arthur Andersen led to the limitation of the audit tenure. Audit quality is measured by current accrual while audit lag is measured by calculating the year in which the same auditor has committed to the auditee, the auditor’s reputation is measured by the peer group amount and the operating complexity is measured using the number of subsidiaries. This study focused on manufacturing companies listed on the Indonesia Stock Exchange 2011 to 2015, using purposive sampling method obtained 225 research samples. Hypothesis testing in this study using multiple regression analysis. Test results show that audit tenure does not affect audit quality, auditor reputation does not affect audit quality while operating complexity affects on tenure audit relationship with audit quality and auditor reputation with audit quality. ABSTRAK Penelitian ini menguji pengaruh tenure audit dan reputasi auditor terhadap kualitas audit dengan kompleksitas operasi sebagai variabel moderasi. Kasus Enron yang melibatkan Arthur Andersen menyebabkan pembatasan tenure audit. Kualitas audit diukur dengan akrual lancar sedangkan tenure audit diukur dengan menghitung tahun dimana auditor yang sama telah melakukan perikatan dengan auditee, reputasi auditor diukur dengan menggunakan kelompok jumlah rekan dan kompleksitas operasi diukur dengan menggunakan jumlah anak perusahaan. Penelitian ini difokuskan pada perusahaan manufaktur yang terdaftar di Bursa Efek Indonesia tahun 2011 sampai dengan 2015, dengan menggunakan motode purposive sampling diperoleh 225 sampel penelitian. Pengujian hipotesis dalam penelitian ini menggunakan analisis regresi berganda. Hasil pengujian menunjukkan bahwa tenure audit tidak berpengaruh terhadap kualitas audit, reputasi auditor tidak berpengaruh pada kualitas audit sedangkan kompleksitas operasi berpengaruh pada hubungan tenure audit dengan kualitas audit dan reputasi Auditor dengan kualitas audit.
