Abstract

Negara Kepulauan merupakan rezim hukum baru dalam UNCLOS 1982. Berdasarkan ketentuan dalam UNCLOS 1982, negara kepulauan harus mengakomodasi hak negara lain untuk melintasi perairan kepulauan. Indonesia sebagai negara kepulauan memiliki kewajiban untuk melaksanakan ketentuan dalam UNCLOS 1982 melalui hukum nasionalnya. Melalui UU No. 6 tahun 1966, PP No. 36 tahun 2002 dan PP No. 37 tahun 2002, Indonesia mengatur tentang hak dan kewajiban bagi negara lain untuk menggunakan hak lintas dalam perairan Indonesia

Abstract

PT FNG is an industry engaged in the glassware industry in Indonesia. In implementing the distribution of PT FNG often experience problems in distribution of its products. Among others, the shortage or excess stock products. Which in turn has an impact on the overall cost performance. With the existence of bullwhip effect, profits earned by the company does not reach its maximum. The method used is forecasting to predict demand for one next year as an input for analysis of inventory performance. By using the model for seasonal products, the inventory of existing demand variability can be reduced by giving large values of the optimal echelon orders so the company gets the maximum profit. This study has obtained the most proper forecasting method for glassware production, and by determining optimal Q, has given influence to conduct coordination or involvement of previous echelon to obtain maximum profits

Abstract

ABSTRACTLearning difficulties from the students is influenced by several factors, such as internal and external factors of the school. The aims of this research to know the factors that cause learning difficulties of the students in the biology subjects. This research is a descriptive research. The population in this research was students of class X, XI IPA, IPA XII Senior  high school 1 Padang gelugur Pasaman who registered in 2012/2013 academic year that amounted of 475 students. The members of the population that used as sample were 25 % of the 475 students, who amounts 120 students, and implemented in February 2013. From the result of the research, the percentage of data obtained from internal factors on intelligence indicators of students in learning, the students attitudes in learning, the talent of students to develop their hobby in learning, the students interest give priority to their desire in learning, the students motivation in learning, with a value of 54.52 % with criteria quite influential. While the percentage of external factors that influence the students in learning difficulties on biology subjects with indicators of how the parents educate the children , the relationship between the family , the situation of house , economy of the family , the teachers teaching methods , curriculum , library , the condition of school buildings , school discipline , playmate , mass media with a value of 52.12 % with criteria quite influential. From the research it can be concluded that the internal and external factors enough to affect learning difficulties of the students.

Abstract

Rafflesia spp. (Rafflesiaceae) have a strategic value from both scientific and conservation viewpoints. To date only very few attempts have succeeded in growing the species ex situ and the main protection measures have been by in situ conservation. More detailed studies are required to understand the relationships between Rafflesia spp. and their host plants in order to improve their management and conservation. Studies on the anatomy, in vitro culture and seed germination in connection with conservation have been conducted in the Bogor Botanic Gardens. Effort to transfer Rafflesia patma to an ex situ conservation area has produced some flowers. However, we encountered a bigger challenge to maintain the long term presence of R. patma in ex situ conservation, since a high number of individuals is required to make the viable population.

Abstract

Perkecambahan secara simbiotik pada anggrek Papilionanthe hookeriana dan Taeniophyllum obtusum dilakukan dengan menginokulasi jamur mikoriza dari kedua jenis anggrek ke biji dari anggrek yang sama dan anggrek yang berbeda. Jamur mikoriza diisolasi dan ditumbuhkan pada media isolasi jamur (FIM) dan perkecambahan dilakukan pada media Oat (OM). Empat jenis jamur diisolasi dari akar P. hookeriana, tetapi hanya dua yang tergolong mikoriza anggrek dan hanya satu jenis dari T. obtusum. Ketiga jenis jamur mikoriza tersebut adalah Ceratobasidium sp. yang penampilannya pada kultur murni agak berbeda. Perkecambahan secara simbiotik pada biji dan jamur mikoriza dari jenis yang sama menghasilkan respons yang sama. Akan tetapi inokulasi silang dari jamur mikoriza T. obtusum pada biji P. hookeriana ternyata memberi hasil yang lebih baik ditinjau dari persentase perkecambahan maupun jumlah rata-rata daun dan akarnya dan keduanya berbeda nyata pada taraf p = 0,05. Inokulasi silang sebaliknya tidak memberi hasil yang memuaskan. Bibit anggrek hasil perkecambahan secara simbiotik mempunyai peran penting dalam konservasinya di alam.

Abstract

A study on epiphytic orchids in three locations (Senturan Forest, Mount Sidi and Mount Jarang) in Malinau District showed that most epiphytic orchids were found in location with moderate light intensity rather than in low and high light intensities. Many orchids were found on parts of trees covered by thin mosses rather than on thick mosses. Three hundred and seventy one orchid specimens were collected from the three locations and at least 71 specimens were new collections to Eka Karya Botanic Garden, Bedugul.

Abstract

Amorphophallus titanium Becc. atau bunga bangkai memperbanyak diri secara alami melalui bijinya, tetapi karena pemasakan bunga betina dan jantan tidal bersamaan waktunya, maka jarang dijumpai buah/bijinya. Perbanyakan secara vegetatif diharapkan dapat dimanfaatkan untuk mempertahankan keragaman genetiknya. Eksplan dari tunas samping umbi Amorphophallus titanum yang berasal dari Lembah Anai, Sumatera Barat ditumbuhkan pada media Murashige-Skoog (MS) and Gamborg B5 dengan penambahan 0,1 mg/I NAA and 1 mg /IBA, dengan dan tanpa 1 mg/I 2,4-D atau 0,1 mg/I NAA dan 0,01 mg/I Kinetin. Penambahan arang aktif tidal< mempengaruhi pertumbuhan tunas dan daun. Selanjutnya kultur yang ditumbuhkan pada media MS dengan penambahan berbagai kadar trans-Cinnamic Acid (t-CA) dan Kinetin dapat menumbuhkan tunas tunggal ataupun ganda dari pucuknya. Kultur yang berasal dari kalus, akar atau potongan pelepah daun pertumbuhan tunasnya terbatas. Media terbaik untuk pertumbuhan tunas akar dan umbi pada media mengandung 0,3 mg/I NAA dan 0,03 mg/I Zeatin.

Abstract

Induksi poliploidi pada bibit Phalaenopsis amabilis telah dilakukan menggunakan kolkisin secara in vivo. Induksi poliploidi dilakukan dengan meneteskan kolkisin pada pucuk bibit P. amabilis.  Tujuan penelitian ini adalah untuk mendapatkan konsentrasi kolkisin yang efektif untuk induksi poliploidi bibit P. amabilis dan  menghasilkan bibit P. amabilis poliploid. Percobaan disusun dalam rancangan kelompok lengkap teracak dengan satu faktor, yaitu konsentrasi kolkisin. Pucuk bibit P. amabilis ditetesi 0,01 ml kolkisin (0, 1000, 2000, 3000, 4000, dan 5000 mg L-1). Hasil percobaan menunjukkan bahwa peningkatan konsentrasi kolkisin dari 1000 sampai 5000 mg L-1 tidak berpengaruh nyata terhadap persentase hidup dan pertumbuhan bibit pada 24 minggu setelah perlakuan (24 MSP). Bibit P. amabilis poliploid dapat dihasilkan pada penetesan kolkisin 1000, 3000, 4000, dan 5000 mg L-1 dengan konsentrasi kolkisin paling efektif adalah 5000 mg L-1. Bibit poliploid memiliki ukuran stomata lebih besar dari bibit diploid sebaliknya kerapatan stomatanya lebih rendah.
