Judul: Hubungan Penerapan Kurikulum Sistem Mayor-Minor dengan Prestasi Belajar Mahasiswa Institut Pertanian Bogor
Abstrak: Institut Pertanian Bogor merupakan salah satu perguruan tinggi terbesar di Indonesia, oleh karena itu IPB memiliki peran yang cukup besar dalam membentuk SDM yang berkualitas. Sumber daya manusia berkualitas dapat terbentuk melalui jalur pendidikan yang berkualitas pula. Hal ini mendorong IPB untuk menyusun kurikulum sistem mayor-minor yang mampu mewujudkan tujuan tersebut. Penelitian ini bertujuan untuk (1) Mengidentifikasi penerapan kurikulum sistem mayor-minor di Institut Pertanian Bogor, (2) Menganalisis persepsi mahasiswa terhadap penerapan kurikulum sistem mayor-minor yang diterapkan di Institut Pertanian Bogor, (3) Menganalisis hubungan penerapan kurikulum sistem mayor-minor dengan prestasi belajar mahasiswa Institut Pertanian Bogor. Penerapan kurikulum sistem mayor-minor yang diteliti adalah perkuliahan mayor, pemilihan minor atau Supporting Course yang mendukung pemahaman mayor dan praktikum sebagai penunjang mayor. Ketiga komponen tersebut kemudian dihubungkan dengan indikator prestasi belajar yaitu kognitif, afektif dan psikomotorik. Analisis hubungan dilakukan dengan menggunakan uji korelasi Rank Spearman. Gambaran tentang penerapan mayor-minor di IPB diperoleh dengan menggunakan analisis deskriptif. Berdasarkan hasil penelitian diperoleh bahwa Pelaksanaan kurikulum sistem mayor-minor di Institut Pertanian Bogor meliputi penerapan mayor-mayor, mayor-minor, mayor-minor dan Supporting Course, serta mayor dan Supporting Course. Pelaksanaan kurikulum sistem mayor-minor dinilai positif oleh mahasiswa namun dalam penerapannya dirasakan masih perlu dilakukan perbaikan terutama pada aspek pengaturan jadwal, ketersediaan sarana dan prasarana yang memadai seperti ruang kelas, sistem teknologi informasi dan fasilitas penunjang lainnya. Persepsi mahasiswa tentang Penerapan Kurikulum Sistem mayor-minor secara keseluruhan memiliki hubungan yang positif dengan peningkatan pengetahuan, sikap pada penguasaan mayor dan pemilihan minor, serta keterampilan pada penguasaan mayor dan pelaksanaan praktikum/praktek lapang. Hal ini berarti penerapan mayor-minor oleh Institut Pertanian Bogor baru dapat memfasilitasi mahasiswa secara optimal pada peningkatan pengetahuan dan belum optimal dalam memfasilitasi mahasiswa pada peningkatan sikap dan keterampilan yang sesuai dengan disiplin ilmu.

Judul: Penjadwalan Mata Kuliah Mayor-Minor: Studi Kasus di FMIPA IPB
Abstrak: A curriculum called a major-minor curriculum has been used at Institut Pertanian Bogor (IPB) in the last six years. Several problems have been identified during the implementation of curriculum, one of them is related to the course scheduling. The problem on course scheduling has become a main problem in the implementation of the curriculum, because it has been found that students from a particular major would not be able to take courses from his/her chosen minor, since the courses are scheduled at the same time. This study addresses the problem on course scheduling for the major-minor curriculum. This problem is modeled as an integer linear program. The model is implemented for scheduling case at FMIPA IPB. The development of the model is initiated by identifying the necessary requirements for the course scheduling. All of these requirements are then formulated as linear equalities and or inequalities. The objective function is to minimize the rejection indicators of lecturers related to the days and time period of courses in the schedule. Several assumptions are used in this model for simplification, one of them, for example all of the classrooms are assumed to be homogen (capacity, equipment, etc.). The model can be improved later by relaxing these assumptions. The solution of the model is obtained using LINGO 11.0. This study produces a scheduling for the course that fulfills all of the requirements for major-minor curricullum at FMIPA IPB. The scheduling minimizes the rejection indicators of lecturers related to the days and time period of courses in the schedule.

Judul: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
