The contribution of taxes to development in Indonesia is very significant to support the government activity. Tax collection involves local government treasurers to carry out calculations to tax reporting. This study aimed to analyze the compliance of the government treasurer in terms of understanding the self-assessment system, service quality, education level, and tax sanctions. Determination of respondents using purposive sampling technique with the criteria that employees that acts as treasurer. The research method applies quantitative research using multiple linear regression models to test the proposed hypothesis(α= 5% : 0.05). The results of the t-test indicate that there is an effect of understanding, education level, and tax sanctions on taxpayer compliance partially (tcount> ttable; p<0.05) while Service Quality has no effect (p>0.05). The results of the F-test indicate that the independent variables have a simultaneous effect (Fcount>Ftable; p<0.05) on Taxpayer Compliance with an accuracy of 66.8% while the rest is influenced by other factors not studied. Government treasurers who understand their duties and are supported by quality tax service services and know the consequences of violations in carrying out their duties will facilitate the implementation of their tax obligations and increase their compliance as taxpayers.

Abstract. Kawan fish (Poropuntius tawarensis) is an endemic fish found in Danau Laut Tawar, Central Aceh, Indonesia. This species has been threatened by ecological partubation, unfrindly fishing practices and pollution. Cryopreservation is one of the ways to maintain the presence of these fish. Cryoprotectant (CP) is a critical material in the cryopreservation and DMSO is a common CP used in cryopreservation. Hence, the aim of the present study was to determine the optimum DMSO concentration for kawan fish sperm. The completely randomized design with 6 treatments and 3 replications were used in this study. The tested treatment was the difference of DMSO concentration, namely; 0, 3%, 6%, 9%; 12%, and 15% DMSO was combined with 5% egg yolk. The ratio of sperm to diluent is 1: 20. The cryotubes containing diluented sperm were evaporated at 5 cm from the surface of liquid nitrogen for 10 min, then stored in a liquid nitrogen container at -1960C for 2 weeks, then thawed and analyzed for the quality. The results showed that fresh sperm of kawan fish had motility of 48.67%, pH 7, milky white, with moderate consistency. The assessment of mass movements shows that the sperm has good quality. The ANOVA test showed that the addition of DMSO in diluents gavee significant effect on sperm motility, fertility and hatchability rates of fish eggs (P 0.05). The highest percentage of sperm motility and fertilization rates of fish eggs were found at concentration of 6%, respectively with the value of 46.67% and 45.67%, respectively. The highest percentage of hatching rate was also found in similar concentration of DMSO with the value of 19.33%. %. The DNA integrity test using the electrophoresis gel method showed that there was damage to DNA fish sperm after freezing, the the lower damage was found at 9% and 12% DMSO. It is concluded that the optimum concentration of DMSO for kawan fish sperm is at 6% of DMSO. Key words: kawan fish (Poropuntius tawarensis), cryopreservation, DMSO, DNA integrity Abstrak. Ikan kawan (Poropuntius tawarensis) merupakan ikan endemik yang terdapat di Danau Laut Tawar, Aceh Tengah, Indonesia. Menurut IUCN (International Union for Conservation of Nature), ikan ini termasuk ikan yang terancam punah oleh sebab kerusakan lingkungan, penangkapan tidak ramah lingkungan dan polusi. Salah satu cara untuk menjaga keberadaan ikan tersebut adalah dengan penerapan metode kriopreservasi sperma. Oleh karena itu, penelitian ini bertujuan untuk menentukan konsentrasi DMSO optimum dan melihat kerusakan DNA yang terjadi pada sperma ikan kawan(Poropontius tawarensis) pasca pembekuan.Metode yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 6 perlakuan dan 3 ulangan.Perlakuan yang diuji adalah perbedaan konsentrasi DMSO dengan konsentrasi 0; 3%; 6%; 9%; 12% dan 15%.DMSO tersebut dikombinasikan dengan 5% kuning telur. Perbandingan sperma dengan pengencer adalah 1 : 20. Semua cryotube yang berisi sperma dan pengencer diuapkan pada jarak 5 cm dari permukaan nitrogen cair selama 10 menit, selanjutnya, disimpan dalam kontainer nitrogen cair bersuhu -1960C untuk disimpan selama 2 minggu. Hasil penelitian menunjukkan bahwa sperma segar ikan kawan memiliki nilai motilitas sebesar 48,67%, pH 7, berwarna putih susu, dengan konsistensi sedang. Penilaian gerakan massa menujukkan bahwa sperma tersebut berkualitas baik. Hasil uji ANOVA menunjukkan bahwa penambahan DMSO dalam pengencer berpengaruh nyata terhadap motilitas, fertilitas dan daya tetas telur ikan kawan (Poropontius tawarensis) (P0,05) setelah pembekuan. Selanjutnya, uji lanjut Duncan menunjukkan bahwa persentase motilitas sperma dan pembuahan telur ikan kawan tertinggi terdapat pada penambahan DMSO dengan konsentrasi 6%, masing-masing sebesar 46,67% dan 45,67%. Persentase penetasan telur tertinggi juga dijumpai pada perlakuan 6% DMSO, dengan nilai 19,33%.

Indonesia merupakan negara kepulauan dengan terumbu karang yang tinggi dan keanekaragaman hayati laut yang kompleks. Namun, setidaknya 45% dari terumbu karang di Indonesia dalam kondisi terancam disebabkan oleh beberapa faktor seperti ulah manusia, perubahan iklim, lingkungan sekitar, lambatnya laju pertumbuhan dan lain sebagainya. Transplantasi karang telah menjadi salah satu pendekatan yang dilakukan untuk konservasi. Penelitian ini mengimplementasikan algoritma Mask Region-based Convolutional Neural Network (Mask R-CNN) dengan Pustaka Detectron2 dalam deteksi dan segmentasi objek untuk menghitung tinggi dan lebar karang transplantasi melalui citra. Metode penelitian melibatkan pengumpulan dataset, pembagian dataset, anotasi dataset, implementasi model, evaluasi model, dan mengitung laju pertumbuhan karang. Implementasi model melibatkan 7 backbone segmentasi instance dengan jadwal laju pembelajaran sebesar 3 kali. Hasil penelitian menunjukkan bahwa dari ketujuh backbone yang diuji X101-FPN dan R101-DC5 menghasilkan presisi dan recall yang lebih baik. Selisih Average Presision (AP) antara kedua model terbaik tersebut untuk segmentasi mask pada Intersection over Union (IoU) maksimum sebesar 2,2% sedangkan untuk deteksi box sebesar 5,8%. Sedangkan selisih Average Recall (AR) untuk segmentasi mask sebesar 8,3% dan deteksi box sebesar 5,2%. Hasil segmentasi X101-FPN dipilih untuk mengukur tinggi dan lebar karang yang telah di transplantasi, sehingga dapat digunakan untuk memantau laju pertumbuhan dari transplantasi karang.

Terumbu karang memiliki peranan penting bagi kehidupan di laut. Namun, ekosistem terumbu karang sangat rentan mengalami kerusakan karena sejumlah faktor seperti aktivitas manusia, perubahan iklim, lambatnya laju pertumbuhan dan sebagainya. Upaya pelestarian terumbu karang telah dilakukan, namun pemantauan masih minim. Oleh karena itu, pemantauan ekosistem terumbu karang perlu ditingkatkan untuk mengetahui kondisi terumbu karang sebenarnya. Persentase tutupan karang adalah indikator yang perlu diketahui sebagai penentuan tingkat kehidupan terumbu karang. Proses pemantauan terumbu karang saat ini masih dilakukan secara konvensional, sehingga proses pemantauan tidak efisien dan perolehan informasi mengenai persentase tutupan karang membutuhkan waktu yang panjang. Penelitian ini mengimplementasikan algoritma Mask Region Convolutional Neural Network (Mask R-CNN) pada library Detectron2 untuk melakukan deteksi dan segmentasi objek tutupan karang pada ekosistem terumbu karang dengan menggunakan citra terumbu karang sebagai input. Model yang digunakan untuk segmentasi instance pada citra terumbu karang ini dilatih dengan menggunakan backbone Residual Network (ResNet) dan Residual Networks Next (ResNeXt) yang terdapat pada library Detectron2. Model backbone dievaluasi berdasarkan matriks presisi dan recall. Hasil penelitian menunjukkan ResNeXt101-FPN merupakan backbone terbaik dalam menghasilkan segmentasi. Hasil proses segmentasi tersebut kemudian digunakan untuk menghitung persentase tutupan karang. Berdasarkan hasil perhitungan, persentase tutupan karang dengan data yang diuji adalah sebesar 86,06%. Dengan demikian, proses perhitungan persentase tutupan karang untuk memantau ekosistem terumbu karang dapat dilakukan dengan efisien dan informasi mengenai persentase tutupan karang dapat diperoleh dalam waktu yang singkat. Abstract Coral reefs have an important role for life in the sea. However, coral reef ecosystems are very vulnerable to damage due to a number of factors such as human activities, climate change, slow growth rates and so on. Efforts to preserve coral reefs have been made, but monitoring remains minimal. Therefore, coral reef ecosystem monitoring needs to be enhanced to assess their actual condition. The percentage of coral cover is an indicator that needs to be known as a determination of the life rate of coral reefs. The current coral reef monitoring process is still carried out conventionally, so the monitoring process is inefficient and obtaining information about the percentage of coral cover takes a long time. This study implements the Mask Region Convolutional Neural Network (Mask R-CNN) algorithm in the Detectron2 library to detect and segment coral cover objects in coral reef ecosystems using coral reef images as input. The model used for instance segmentation on coral reef images was trained using the Residual Network (ResNet) and Residual Networks Next (ResNeXt) backbones, which are available in the Detectron2 library. The backbone model is evaluated based on precision and recall matrices. The results show that ResNeXt101-FPN is the best backbone in producing segmentation. The results of the segmentation process are then used to calculate the percentage of coral cover. Based on the calculation results, the percentage of coral cover with the tested data was 86.06%. Thus, the process of calculating the coral cover percentage to monitor coral reef ecosystems can be carried out efficiently and information about the coral cover percentage can be obtained in a short time.
