Judul: Capillary Irigation and Application of Fertilizer Effect on Growth and Yield of Eggplant.
Abstrak: Irrigation through proper capillary irrigation will provide enough available water for eggplant plants to grow and produce properly. The research was arranged in Randomized Complete Block Design of two factors with three replications. The first factor has 4 levels and the second factor has 5 levels. resulting in 20 combinations and repeated 3 times resulting in 60 experimental units. The first factor was the number of capillary wick in the existing PVC pipe that was 1, 2, 3, and 4 capillary wick with the distance between capillary wick was 3 cm. The second factor was the fertilizer application method that was P1 without fertilizer, P2 of fertilizer was given 0% through the water and 100% through the soil, P3 of fertilizer was given 33,3% through the water and the rest through the soil, P4 fertilizer was given 66,6% through the water and the rest trough the soil, P5 100% fertilizer through the water. The results of this study indicated that combination of K1P1 (one capillary wick and without fertilizers) gave the maximum production of marketable eggplant. The method of applying the fertilizer affected plant growth. Treatment without fertilizer produces the maximum number of leaves. The number of capillary wick give effect of plant to growth, one capillary wick give maximum number of leaves.

Judul: Growth of Water Spinach and Spinach Due to the Application of Inorganic Liquid Fertilizer in the Hydroponic System
Abstrak: Hidroponik adalah salah satu metode alternatif dalam budidaya sayur, metode ini tidak memerlukan area yang luas. Produksi dari hidroponik dapat ditingkatkan dengan pemenuhan nutrisi yang tepat. Penelitian ini bertujuan menganalisis efek penambahan pupuk anorganik cair pada larutan hara AB mix terhadap pertumbuhan tanaman kangkung dan bayam. Rancangan penelitian yang digunakan adalah Rancangan Acak Kelompok. Perlakuan yang diamati adalah konsentrasi larutan hara yang terdiri dari 3 taraf. Perbandingan air, larutan A, larutan B, dan pupuk cair (v/v) yaitu P0 (kontrol) = 1000:5:5:0, P1 =1000:5:5:5, dan P2 = 1000:5:5:15. Parameter yang diamati adalah tinggi tanaman, jumlah daun, jumlah cabang, luas daun, berat segar, berat kering, dilakukan juga uji kualitatif kandungan nitrat daun. Hasil penelitian menunjukkan bahwa perlakuan P0 memiliki pertumbuhan tercepat, sedangkan pertumbuhan paling lambat terlihat pada P2. Uji nitrat daun P2 menunjukkan hasil yang negatif. Perlakuan P0 juga memiliki berat segar dan berat kering tanaman yang paling tinggi dibanding dua perlakuan lainnya. Penambahan pupuk anorganik cair tidak dapat meningkatkan pertumbuhan pada kangkung dan bayam., Hydroponics is an alternative method in vegetable cultivation, this method does not require a large area. Hydroponics production can be increased with the fulfilment of proper nutrition. This research aimed to analyze the effect of adding liquid inorganic fertilizer to the AB mix nutrient solution on water spinach and spinach growth. This research used a Randomized Block Design. The treatments observed were the concentration of nutrient solution which consisted of 3 levels. The treatments were mixed of water, solution A, solution B, and liquid fertilizer (v/v), namely P0 (control) = 1000:5:5:0, P1 =1000:5:5:5, and P2 = 1000:5:5:15. The parameters observed were plant's height, number of leaves, number of branches, leaves area, leaves nitrate content, and plant fresh and dry weights. The results showed that the P0 treatment had the fastest growth, while the slowest growth was seen in P2. The leaf nitrate test of P2 plants showed negative results. The P0 treatment also had the highest fresh and dry weights per plant compared to the other two treatments. The addition of liquid inorganic fertilizer did not increase the growth of water spinach and spinach.

Judul: Pengembangan model markov tersembunyi pada identifikasi pembicara
Abstrak: Model Markov Tersembunyi merupakan suatu model yang tersusun dari dua buah proses stokastik, yaitu rantai Markov untuk menampung kemajuan temporal dan proses yang teramati untuk menampung variasi akustik. Model ini dapat digunakan sebagai metode pencocokan pola pada sistem identifikasi pembicaraan. Setiap model mewakili referensi pola dari seorang pembicara di dalam sistem identifikasi pembicara.
