No full textABSTRAK Fadilah, Mira . 2018. Pengaruh Variasi Suhu dan Perbandingan Massa NaOH pada Sintesis Karboksimetil k-Karagenan (CMKC) dengan Asam Trikloroasetat (TCA). Skripsi, Jurusan Kimia, Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Negeri Malang. Pembimbing: (I) Dr. Irma Kartika K, S.Si., M.Si., (II) Dr. Siti Marfu’ah, M.S. Kata Kunci: k-karagenan, karboksimetilasi, suhu, NaOH, alkalisasi, fisikokimia. Karboksimetil kappa-Karagenan (CMKC) merupakan produk hasil karboksimetilasi k-karagenan. Konversi gugus hidroksil menjadi gugus karboksimetil pada proses karboksimetilasi berpengaruh pada karakter k-karagenan antara lain viskositas, kelarutan dan kemampuan mengikat air. Banyaknya gugus –OH yang dapat disubstitusi dinyatakan sebagai derajat substitusi (DS). Peningkatan nilai DS dapat dilakukan dengan cara mengoptimasi suhu alkalisasi serta massa NaOH yang ditambahkan pada proses karboksimetilasi. Penelitian ini adalah penelitian eksperimental dengan tujuan mengoptimasi metode pembuatan karboksimetil kappa-karagenan yang dilakukan dengan cara memvariasi suhu alkalisasi dan massa natrium hidroksida yang ditambahkan. Penelitian dilakukan dalam dua tahap, yaitu (1) pembuatan karboksimetil k-karagenan (CMKC) dengan beberapa variasi jumlah NaOH dan suhu reaksi pada tahap alkalisasi, (2) karakterisasi sifat fisikokimia produk yang dihasilkan meliputi nilai derajat substitusi (DS), FTIR, kadar air, kelarutan, kemampuan swelling dan viskositas. Hasil penelitian ini adalah karboksimetil k-karagenan yang disintesis menggunakan agen eterifikasi asam trikloroasetat (TCA) ditandai dengan munculnya serapan FTIR pada bilangan gelombang sekitar 1650 cm-1 dan 1410 cm-1 (serapan gugus karbonil). Selain itu juga ditunjukkan dengan perubahan sifat fisikokimia yang berbeda dari molekul awalnya. Suhu alkalisasi optimum pada proses karboksimetilasi k-karagenan adalah 40oC dengan nilai DS yang diperoleh adlaah 0,87, kadar air 0,9650%, kelarutan dalam air sebesar 8,83 g/L dengan % terlarut 87,5124 %, suhu gelling pada 60oC serta viskositas sebesar 3 cP. Peningkatan suhu alkalisasi dapat menurunkan nilai DS, juga berpengaruh pada kadar air dan kelarutan CMKC yang dihasilkan. Sedangkan massa NaOH optimum yang ditambahkan pada proses karboksimetilasi k-karagenan untuk memperoleh nilai DS yang paling besar (1,6) adalah 6,0011 g, dengan kadar air sebesar 1,0350%, kelarutan dalam air sebesar 9,55 g/L dengan %terlarut 95,1195%, suhu gelling pada 70oC serta viskositas sebesar 3,5 cP. Penambahan yang lebih banyak dari 6,0011 g NaOH dapat menurunkan nilai DS produk dikarenakan semakin banyaknya produk samping yang terbentuk
The ecological and socio-economic impacts of the lionfish invasion in the Southern Caribbean
No full textThe Indo-Pacific lionfish (Pterois volitans) is a venomous, voracious predator with a high dispersal capactity. In the space of 30 years, it has infiltrated an array of habitats, inhabited a depth range of > 300 m and exceeded the size and density reported in the native range, demonstrating the difficulty of effective lionfish management. If left unmanaged, lionfish pose a significant, but still uncertain, threat to Caribbean ecosystems thereby warranting the need for effective and efficient, tailored management schemes. Since their confirmation in Bonaire and Curacao in October 2009, an extensive monitoring program was established by the author in collaboration with CIEE Research Station Bonaire whereby >11,000 lionfish were documented and their population dynamics, reproductive and feeding ecology analysed in relation to local management strategies. The types of education and management strategies applied were evaluated based on their benefits and limitations to make recommendations for areas early in the invasion timeline. Finally efficiency of removal activities in Bonaire and Curacao were assessed and suggestions made on when and how often to remove lionfish. Socio-economic questionnaires were conducted to determine the profile and motivations of lionfish hunters, and a cost-benefit-analysis performed to assess economic effects of the invasion. Knowledge gained from this research is beneficial for tailoring future management through recommendations of which lionfish to remove, how often and which tools, methods and groups are most effective. This work revealed that dusk was the most effective time for lionfish removal and that by focusing removal efforts in the 15 – 25m depth range, this allowed for the depletion of a higher proportion of individuals in the 101 - 200mm size class. This research also revealed how valuable a prepared and rapid response to management was and how important a dedicated volunteer removal effort is to controlling the lionfish
populations in the future

Tindakan Bullying di Sekolah : Perspektif Sosiologi Pendidikan
Get PDFBullying merupakan suatu kenyataan universal yang ada sepanjang sejarah peradaban manusia. Pada dasarnya memang bullying sudah lama dikenal, terjadi dan berkembang mengikuti perkembangan zaman dan peradaban manusia. Tindakan bullying dapat dilakukan oleh siapa saja, di mana saja, kapan saja dan dengan berbagai bentuk. Tindakan bullying ini termasuk ke dalam penyimpangan dan kenalan remaja yang dilakukan oleh para pelajar. Teori kontrol oleh Hirski menyatakan bahwa penyimpangan dan bahkan kriminalitas atau pelaku kriminal merupakan bukti kegagalan kelompok-kelompok sosial konvensional seperti keluarga, sekolah atau kelompok-kelompok dominan lainnya dalam mengikat individu agar tetap conform. Untuk itu diperlukan kontrol/pengendalian dari keluarga yaitu orang tua, pihak sekolah dan komunitas ekstrakulikuler, sehingga kenakalan pelajar tidak terjadi lagi dalam dunia pendidikan. Sosiologi pendidikan sebagai suatu kajian yang mempelajari hubungan antara masyarakat, yang di dalamnya terjadi interaksi sosial dengan pendidikan. Sosiologi mencakup masyarakat baik secara makro (masyarakat keseluruhan), meso (proses belajar di sekolah), hingga bagian masyarakat terkecil yaitu mikro (individu di dalam masyarakat). Sekolah sebagai salah satu institusi pendidikan juga dipercaya oleh masyarakat sebagai proses pembudayaan sekaligus wahana pengembangan potensi kemanusiaan. Namun sayangnya dalam sejumlah kasus, justru menunjukkan bahwa sekolah dapat menjadi tempat berlangsungnya verbal dan nonverbal, seperti bullying. Salah satu kejadian yang sekarang sedang menjadi perhatian di dalam dunia pendidikan adalah terkait bullying di sekolah, bullying di sekolah adalah masalah yang sering terjadi dan berdampak buruk pada tatanan sosial di sekolah. Tujuan dari adanya penelitian ini adalah untuk mendeskripsikan tentang bullying di Sekolah dalam tinjauan perspektif Sosiologi pendidikan. Metode yang digunakan dalam penelitian ini adalah menggunakan studi kasus dan literature review. Dalam konteks sosiologi pendidikan, bullying dianggap sebagai fenomena sosial yang terjadi di lingkungan sekolah. Sosiologi pendidikan juga menyempurnakan pentingnya peran sekolah, keluarga dan masyarakat dalam mencegah bullying. Baik keluarga, Sekolah maupun lingkungan masyarakat dapat memberikan pendidikan dan pelatihan tentang pentingnya nilai akhlak mulia, moral, sopan santun, toleransi, penghargaan terhadap yang lebih tua dan kepada sesama. Beberapa kontrol sosial dan upaya untuk mengatasi perilaku bullying yang dapat diberikan oleh sekolah yaitu dengan cara membuat konsultasi layanan konseling dan melakukan pengawasan dengan ketat, memberikan teguran dan ancaman, dan bisa juga dengan dengan cara pemberian sanksi

KETERBELAHAN HASRAT KEBEBASAN MASYARAKAT TURKISTAN DALAM NOVEL LAYALI TURKISTAN
Get PDFDesire always accompanies the subject throughout his life. Subjects
always identify something outside of themselves to find a complete identity.
From these desires the subject has a need (need), and a desire that becomes
a desire. However, symbolic reality necessitates the existence of a split and
divided subject, because after all desire involves consciousness (ego) which
is disrupted by the desires of others. This reality also occurs in the novel
Layālī Turkistān by Najīb al-Kailānī which describes the free structure of
Turkistan Society as a whole, and then crumbled when China and Russia
came to colonize. The process of subject division in literary texts represents
the author, how the author cannot be separated in the text process. This study
aims to see how the divided freedom of the Turkistan Society occurs in the
novel Layālī Turkistān.This study uses a descriptive qualitative research
method with Lacanian psychoanalysis reading, where the reading is to see
the divided freedom of the Turkistan Society in the novel Layālī Turkistān
and see the desires that shape the subject of the novel character who is also
the subject of the author himself. This research also needs to use the
historical reading of the author's subject as a whole.From the novel Layālī
Turkistān, using the psychoanalytic perspective of Jacques Lacan, the
researcher finds how the subjects in the novel are underprivileged due to the
colonial acts carried out by China and Russia to take advantage of Turkistan.
The resistance of desire that every character in Layālī Turkistān's novel does
is a re-satisfaction of the jouissance that has been captured by others in him.
The action is a choice that they identify continuously to find the 'ideal ego'.
The discourse on the divided desire for freedom of the Turkistan Society in
the novel is also a form of resistance by the author Najīb al-Kailānī to fulfill
his desires. It can be seen how his background and concern for Muslims
around the world are trying to be discriminated against by communist
movements
