Published: October 2017

Makalah ini melaporkan hasil studi tahap pertama tentang kelayakan pengembangan Jurusan Diploma IV Perhotelan, di Fakultas Ekonomi, Undiksha. Riset ini dimulai dari hasil analisis awal tentang keberadaan Jurusan Diploma III Perhotelan di mana jumlah mahasiswa dari tahun ke tahun bersifat stagnan, yaitu satu kelas saja. Hal ini menunjukkan tidak adanya pertumbuhan yang signifikan dan berarti dari segi jumlah mahasiswa, padahal industri perhotelan dan pariwisata di Bali khususnya, terus berkembang bahkan dengan pesat. Riset ini dilaksanakan guna menjawab kesenjangan tersebut, yaitu dengan memahami bagaimana potensi Jurusan DIII perhotelan menjadi DIV. Pada tahap pertama, riset dilakukan dengan menggali kelebihan dan kekuatan serta peluang dan tantangan DIII menjadi DIV Perhotelan. Riset pada tahap kedua akan mmelibatkan industri dan pemangku kepentingan lainnya. Adapun responden penelitian tahap ini adalah civitas akademika internal. Sementara itu, pendekatan yang digunakan adalah metode kualitatif, dengan menggunakan Analysis SWOT. Hasil analisis menunjukkan beberapa kekuatan dan kelemahan serta peluang dan tantangan jurusan. Hal yang menarik adalah bahwa mayoritas responden yang adalah dosen menyarankan belum perlunya dilakukan pengembangan DIII menjadi DIV. Dengan kata lain, jurusan DIII Perhotelan dibiarkan saja sebagaimana adanya untuk saat ini. Sementara itu, kebanyakan responden mahasiswa menyatakan setuju, tanpa mengeskpresikan atau menambahkan argumentasi atau alasan. Lebih jauh, secara menyeluruh, responden cenderung memilih  pengembangan S1 Pariwisata. Selanjutnya, hasil riset ini memberi arah bagi kelanjutan riset tahap II.

Tujuan kegiatan pengabdian ini adalah untuk melatih Siswa SMK di Singaraja tentang product knowledge hotel pada bagian housekeeping dan food and beverage service. Hotel sebagai salah satu industri pariwisata dalam praktiknya sangat memerhatikan sikap pelayanan yang diberikan oleh pelayan hotel kepada konsumen yang datang. Dalam hal ini, semua pelayanan di hotel dituntut memiliki kualitas yang baik dan mampu memuaskan konsumen yang datang, terlebih lagi jika konsumen yang dilayaninya adalah wisatawan mancanegara yang menuntut standar pelayanan tinggi yakni standar internasional. Oleh sebab itu, seluruh karyawan yang  bekerja di industri hotel baik pada level training, kontrak maupun karyawan tetap dituntut untuk memiliki keterampilan (skill), pengetahuan (knowledge) dan sikap (attitude) yang baik. Berdasarkan temuan di industri, salah satu kelemahan lulusan SMK (Sekolah Menengah Kejuruan) adalah kurangnya pemahaman tentang product knowledge hotel. Sebagaimana yang dikemukakan oleh salah satu manajer hotel yang berlokasi di daerah Memahami permasalahan tersebut, maka pada kesempatan ini, program pelatihan product knowledge hotel diberikan kepada siswa SMK Singaraja, yakni SMK N1 Singaraja dan SMK Melalui pelatihan dan pendampingan ini diharapkan dapat meningkatkan pemahaman siswa SMK terhadap product knowledge di hotel, khususnya bidang housekeeping dan food and beverage service.

Published: October 2017

A Educação ambiental possui uma perspectiva interdisciplinar, segundo Dias (1992), e perante tantos problemas ambientais, é uma necessidade no ensino fundamental. Os jogos pedagógicos servem de apoio durante o processo de aprendizagem e por terem caráter lúdico, proporcionam atividades educacionais que podem ser mais criativas e motivadoras. O presente trabalho tem por objetivo apresentar a elaboração de um jogo ecológico-pedagógico que envolve design gráfico e de produtos que visa conscientizar seus jogadores sobre o meio ambiente e sensibiliza-los por essas questões. O jogo aborda algumas questões do meio ambiente na cidade de São Paulo, a escassez de recursos naturais, destacando a água, o descarte inadequado de dejetos e a poluição do rio Pinheiros, utilizando as capivaras que habitam as margens deste rio como recurso lúdico para contextualizar o objetivo. Por meio do jogo de tabuleiro cooperativo, propõem-se despertar o interesse e a preocupação nos participantes sobre a condição em que o rio Pinheiros se encontra e sobre a escassez de recursos naturais na cidade de São Paulo. Além do ensino de Ecologia e Educação Ambiental, o projeto visa a integração e a colaboração entre os jogadores, motivando-os de tal modo que possam participar ativamente da melhoria desse quadro.

AbstractAcetosolv process is one of making pulp alternative which friendly environmental. Making pulp of banana stem with a solution of acetic acid cooking (CH3COOH) and catalyst sulfate acid (H2SO4) are expected to take place simultaneously, either delignification process or degradation of polisakarida. The variable process is looked in this research is concentration of acetic acid (70%-wt, 80%-wt, 90-wt%) with cooking time (1 hour, 2 hours, 3 hours), whereas constant variabel in this research in liquid to solid ratio (20/1), concentration catalyst (0.6%-wt), and measure of raw materials (±1,5cm). The result of the study exhibit banana stem may become as raw material in making pulp which using acetosolv. Yield pulp around 50.64 % -57.13% with content of lignin pulp 12.5% -19.42%, and content of cellulose pulp 80,85%-82,28%, which is variation according to process. The best condition which produce yield with high cellulose level and low lignin are gotten at concentration of cooking 90%-wt with time of cooking 3 hours. The result shows that banana stem pulp have yield of 50.64%, lignin 12.5% and cellulose 87.49%. Implementation knowledge of student senior high school 1 Tembilahan to exploiting banana stem in making pulp categorized as "very good" because the final results show the percentage obtained 86.78% which lies in the range of 81% -100%, this percentage is in the category of "very good ''. Keywords:  Banana stem, Acetosolv, Yield pulp, Lignin, Cellulose, Implementation.

AbstrakMeningkatnya penggunaan plastik diikuti dengan besarnya kepedulian terhadap isu lingkungan mengenai pembuangan produk plastik sintetis yang sulit terurai. Salah satu alternatif untuk mengatasinya adalah dengan memodifikasi plastik agar bersifat biodegradabel. Plastik biodegradabel (plastik ramah lingkungan) dirancang mampu terdekomposisi di alam. Tingkat di biodegradasi yang terjadi tergantung pada kondisi tanah seperti suhu, kadar air, tingkat aerasi, keasaman dan konsentrasi mikroorganisme sendiri. Berdasarkan hal diatas, maka dilakukan penelitian dengan tujuan mengetahui efektifitas penguraian plastik ramah lingkungan dengan metode pengomposan dalam tanah gambut (TG) dan tanah sampah, serta faktor pH. Dari hasil penelitian kami mendapatkan bahwa pada semua perlakuan uji pada hari ke-20 sampai hari ke-60 terjadi peningkatan persentase penurunan berat plastik ecoplas dan oxium. Sedangkan persentase perubahan berat plastik terbesar dari proses biodegradasi terhadap semua perlakuan uji adalah pada  TG3pada hari ke-60 yaitu 0,45%. Secara umum, jika pH tanah dibuat semakin asam, maka menyebabkan penguraian plastik semakin bertambah.Kata Kunci : Plastik, Mikroorganisme tanah, lahan gambut.
