Perairan Pulau Panjang dan Teluk Awur merupakan lokasi wisata dan dimanfaatkan masyarakat sebagai sumber mata pencaharian. Zooplankton berperan sebagai konsumen tingkat satu yang menghubungkan fitoplankton dengan organisme tingkat tinggi. Tujuan dari penelitian ini adalah  untuk mengetahui komposisi, kelimpahan, indeks keanekaragaman, indeks keseragaman, indeks dominansi zooplankton di perairan Pulau Panjang dan teluk Awur. Metode yang digunakan dalam penelitian ini adalah deskriptif eksploratif dan penentuan lokasi menggunakan metode purposif sampling. Penelitian ini terbagi atas 5 stasiun dengan 3 sub-stasiun di setiap stasiun. Pengambilan sampel zooplankton dengan cara aktif dengan menarik planktonet secara horizontal. Pengambilan sampel dilakukan pada bulan Januari 2017. Hasil penelitian diperoleh 31 genera zooplankton dari 8 fila di perairan Pulau Panjang dan 20 genera zooplankton dari 3 fila di perairan Teluk Awur. Kelimpahan rata-rata zooplankton berkisar antara 378 Ind/L – 892 Ind/L di perairan Pulau Panjang dan 341 Ind/L – 446 Ind/L di perairan Teluk Awur. Indeks Keanekaragaman zooplankton menunjukkan nilai  2,36 – 2,68 di perairan Pulau Panjang dan 2,29 – 2,62 di perairan Teluk Awur yang termasuk dalam kategori sedang. Indeks keseragaman zooplankton menunjukkan nilai 0,75 – 0,88 di perairan Pulau Panjang dan 0,89 – 0,94 di perairan Teluk Awur yang termasuk dalam kategori Tinggi. Indeks dominansi di kedua lokasi menunjukkan tidak ada genus tertentu yang mendominasi dengan nilai 0,12 – 0,25 di perairan Pulau panjang dan 0,07 – 0,11 di perairan Teluk Awur.  Panjang Island and Teluk Awur waters are a marine tourism places and both the waters are also utilized as a source of community livelihood. Zooplankton role is as the first-level consumer that connects phytoplankton with the high-level organisms.

ABSTRAKPenelitian ini bertujuan untuk menganalisis pengaruh manajemen laba akrual, leverage, good corporate governance terhadap penghindaran pajak pada perusahaan sektor industri dasar dan kimia. Populasi penelitian ini adalah seluruh perusahaan sektor industri dasar dan kimia yang terdaftar di Bursa EFek Indonesia periode 2015─2019. Sampel penelitian dipilih dengan metode purposive sampling dan diperoleh sebanyak 12 perusahaan. Analisis data dalam penelitian ini menggunakan analisis regresi berganda. Hasil analisis menunjukkan bahwa manajemen laba, kepemilikan institusional, dan proporsi dewan komisaris independen tidak berpengaruh terhadap penghindaran pajak, sedangkan leverage dan komite audit berpengaruh terhadap perilaku penghindaran pajak. Perusahaan sebaiknya lebih meningkatkan kinerja dewan komisaris khususnya dewan komisaris independen. Perusahaan harus memperhatikan level kompetisi, keahlian, dana pengalaman dari setiap anggota dewan agar terhindar dari tindakan kecurangan khususnya penghindaran pajak diantaranya dengan menambah jumlah dewan komisaris independen yang tidak terafiliasi dengan perusahaan dan memiliki pengetahuan lebih mengenai perpajakan perusahaan serta memiliki tingkat independensi yang tinggi. ABSTRACTThis study aims to analyze the effect of accrual earnings management, leverage, good corporate governance on tax avoidance in basic and chemical industry companies. The population of this research are all basic and chemical industrial sector companies listed on the Indonesia Stock Exchange for the period 2015-2019. The research sample was selected by purposive sampling method and obtained as many as 12 companies. Data analysis in this study used multiple regression analysis. The results of the analysis show that earnings management has no effect on tax avoidance, while leverage, institutional ownership, the proportion of independent commissioners, and audit committees affect tax avoidance behavior. The company should further improve the performance of the board of commissioners, especially the independent board of commissioners. Companies must pay attention to the level of competition, expertise, and experience of each member of the board to avoid fraud, especially tax avoidance, including by increasing the number of independent commissioners who are not affiliated with the company and have more knowledge about corporate taxation and have a high level of independence.

This research was aimed to develop and to evaluate the quality of the innovative multimedia through social lab to promote perception of good citizenship according to democratic values, to evaluate the perception results, to evaluate the sampling group’s satisfaction towards the development of innovative multimedia and to evaluate the feedback by the organizer. The sampling group in this study consisted of 2 groups. The first group was 30 state enterprise entrepreneurs from the Community under the Bridge Zone 1 at soi Pracha-Utit 76, the Community at the Back of the Suanthonburirom Park and the Community Moo 3 in the Bang Mod area. They were chosen using purposive sampling method out of those who were filmed in a short film and were willing to be models for a desk calendar and to fill out the questionnaires. The second group was 50 students from the ETM 358 Marketing Communication course and the ETM 361 Presentation Skill 2 course in the second semester of the academic year 2018. They were chosen using purposive sampling method out of those who participated in at least 2 social labs and participated in all the short film events at the cinema. The statistical methods in this research were mean score, standard deviation and feedback by the organizer. The results from the research and development were as follows: The results from the development of the innovative multimedia through social lab to promote perception of good citizenship according to democratic values contained 3 phases with the following major media, minor media and supporting media: short film, desk calendar and facebook page, vinyl banner for publicity with QR code and events to preview the short film and to screen the film at Major Cineplex cinema at Tesco Lotus Bangpakok. The quality of the media contents as evaluated by the expert panel was at a good level (x  = 4.25, S.D. = 0.72). The quality of the media presentation as evaluated by the expert panel was at a very good (x  = 4.61, S.D. = 0.32). The sampling group’s perception of the innovative multimedia was at a high level ( x  = 4.42, S.D = 0.68). The sampling group’s satisfaction towards the innovative multimedia was at a high level ( x  = 4.36, S.D = 0.72). These values confirmed the research hypotheses. The feedback or after action review by the learners showed that the majority had a good attitude towards service learning in conjunction with community-based learning in accordance with the research hypothesis. It was found that social work made students stronger and allowed them to think, analyze and engage in real work. They could communicate collaboratively through presentation and social media network for this course.
