Abstract

The International Union for the Conservation of Nature and Natural Resource (IUCN) Red List found that there are currently over 8.000 critically endangered species and the number seems likely to rise in the future. One of the species included in the IUCN Red List is Eos histrio, also known as the Red-and-blue lory, a bird endemic to Indonesia that inhabits Nusa Utara Islands, North Sulawesi. It lives in a forest with tall trees as its natural habitat. According to the Central Bureau of Statistics (BPS), the forest area is decreasing every year and has caused the bird to lose their habitats and its population is declining. IUCN also reported that there are 8.230 – 21.400 Eos histrio in 1999, however in 2016, it was only around 5.500 – 14.000. Its population will be declining due to extensive deforestation and poor conservation. Using Pontryagin maximum principle, this study found that one of the methods to protect the Eos histrio population is by reducing deforestation in North Sulawesi by at least 10% where the population of the bird could increase within a year.

Abstract

Abstrak. Aljabar Lie sl(n, C) merupakan salah satu jenis aljabar Lie klasik. Tujuan dari penelitian ini untuk melihat apa saja aljabar Lie lain yang dapat dihasilkan dari kontraksi pertingkatan aljabar Lie sl(n, C). Aljabar Lie yang diperoleh akan disebut sebagai solusi dari kontraksi pertingkatan. Secara khusus, akan ditinjau kasus pada nilai n = 3 dan pertingkatan yang ditinjau adalah pertingkatan Pauli. Pertingkatan Pauli pada sl(3, C) merupakan salah satu fine grading (pertingkatan yang terbaik) dari empat fine grading yang bisa dilakukan pada sl(3, C). Untuk kontraksi pertingkatan Pauli pada sl(3, C), terdapat 48 persamaan kontraksi yang dapat digunakan untuk memperoleh solusi dari kontraksi pertingkatan Pauli pada sl(3, C). Untuk menyelesaikan persamaan kontraksi tersebut, digunakan bantuan dari grup simetri pertingkatan Pauli sl(3, C). Di akhir, penulis memberikan sedikit hasil lain yaitu kasus ketika n = 2 dan n = 4 serta dekomposisi Levi pada kontraksi pertingkatan Pauli sl(3, C).

Abstract

Data yang diperoleh melalui survei pengguna dan studi pelacakan menunjukkan bahwa korelasi antara kepuasan pengguna dengan variabel seperti faktor organisasi, mata kuliah yang diambil selama dan setelah masa studi, peran institusi pendidikan tinggi, serta kompetensi alumni tidak dapat diabaikan. Berdasarkan analisis, kompetensi alumni dan kontribusi institusi pendidikan tinggi menunjukkan korelasi positif tertinggi (0,8). Kemampuan bahasa asing, pengetahuan lintas disiplin, penyelesaian masalah kompleks, negosiasi, kemampuan komunikasi, manajemen diri dan orang lain, pembelajaran aktif, serta inovasi dan/atau kreativitas merupakan keterampilan keras dan lunak yang masih perlu ditingkatkan oleh alumni ketika bekerja di sektor perbankan. Menurut pengguna, institusi pendidikan tinggi masih kurang dalam membekali lulusan dengan keterampilan seperti pemecahan masalah, pembuatan materi presentasi, praktik ilmiah, komunikasi, negosiasi, keterampilan interpersonal, sikap, dan kerja sama tim.Data obtained through user surveys and tracer studies indicate that the correlation between user satisfaction and variables such as organizational factors, courses taken during and after university, the role of higher education institutions, and alumni competencies cannot be overlooked. Based on the analysis, alumni competencies and the contribution of higher education institutions show the highest positive correlation (0.8). Foreign language skills, interdisciplinary knowledge, complex problem-solving, negotiation, communication abilities, self and people management, active learning, and innovation and/or creativity are hard and soft skills that alumni still need to enhance when working in the banking sector. According to users, higher education institutions fall short in equipping graduates with skills such as problem-solving, creating presentation materials, scientific practice, communication, negotiation, interpersonal skills, attitude, and teamwork.
