Judul: Perlakuan benih untuk pengendalian penyakit busuk phytophthora, peningkatan hasil dan mutu benih cabai merah (Capsicum annuum L.), Seed Treatment for controlling phytophthora blight disease and improving yield and seed quality of hot pepper (Capsicum anmum L.)
Abstrak: Penggunaan benih bermutu rendah dan infeksi penyakit merupakan penyebab rendahnya produktivitas cabai di Indonesia. Busuk phytophthora termasuk salah satu penyakit yang mengakibatkan kehilangan hasil cabai di Indonesia., Low quality seds and infections diseases are the causes of low productivity of hot peppers in Indonesia. Phytophthora blight disease is one of the diseases that causes the yield loss of hot pepper in Indonesia. The disease is still difficult to control because, in addition to no resistant varieties available yet, it can be carried in seeds and also transferred from the soil.

Judul: Perlakuan Benih Cabai (Capsicum annuum L.) dengan Rizobakteri untuk Mengendalikan Phytophthora capsici, Meningkatkan Vigor Benih, dan Pertumbuhan Tanaman
Abstrak: Rhizobacteria seed treatment was an alternative way instead of using chemicals to combat plant disease. The objectives of this research were (1) to select rhizobacteria isolates which inhibiting Phytophthora capsici growth; and (2) to study the effect of seed treatment using rhizobacteria on P. capsici growth, seed vigor and plant growth of hot pepper. This research consisted of three experiments, all experiments were arranged in completely randomized design using one factor. The first experiment consisted of 24 levels of rhizobacteria i.e. 23 isolates of rhizobacteria and P. capsici isolate (control). The second experiment (on the seedbed) consisted of five levels of seed treatments i.e. ST116B rhizobacteria, ST156 rhizobacteria, E3 rhizobacteria, metalaxyl, and control. The third experiment (in the green house) consisted of six levels of seed treatments i.e. ST116B rhizobacteria, ST156 rhizobacteria, E3 rhizobacteria, metalaxyl, positive control, and negative control. Results of in vitro experiment showed that three of 23 isolates tested i.e. ST156, ST116B, and E3 obstructed P. capsici growth. Seed treatments using ST116B, ST156, and E3 rhizobacteria increased seed vigor (vigor index). The best seed treatment increasing plant growth (number of leaves) and potentially controlling phytophthora blight disease was using ST116B rhizobacteria

Judul: Konstruksi Persamaan Friedmann Alam Semesta Friedmann-Lemaitre-Robertson-Walker Termodifikasi Materi Gelap Superfluida
Abstrak: Kosmologi merupakan salah satu objek kajian dari teori relativitas umum. Salah satu model dalam kosmologi adalah model kosmologi Friedmann. Model kosmologi Friedmann dibangun berdasarkan asumsi bahwa materi dan energi terdistribusi secara homogen dan isotropik di alam semesta. Teori relativitas umum dapat dimodifikasi melalui pendekatan teori materi gelap superfluida (MGS). Persamaan medan Einstein untuk teori MGS dapat dirumuskan melalui prinsip aksi dengan memodifikasi Lagrangian pada aksi teori MGS. Selanjutnya dengan memilih metrik Friedmann-Lemaitre-Robertson-Walker (FLRW) datar dengan indeks kurvatur sama dengan nol, dapat dibangun suatu bentuk persamaan Friedmann yang dimodifikasi teori MGS.
