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: Optimization of Fertilization Dose in Eggplant Cultivation using Fertigation through Drip Irrigation
Abstrak: Terung banyak dibudidayakan di Indonesia namun masih memiliki angka produktivitas nasional yang cukup rendah. Peningkatan produktivitas dapat dilakukan dengan menyediakan unsur hara secara tepat melalui analisis tanah dan irigasi tetes. Penelitian bertujuan mendapatkan dosis optimum rekomendasi pemupukan tanaman terung berdasarkan uji analisis tanah Mehlich 1. Penelitian dilakukan di lahan terbuka Kebun Percobaan Cikarawang, Institut Pertanian Bogor selama bulan Juni sampai November 2022. Penelitian ini menggunakan rancangan kelompok lengkap teracak (RKLT) dengan satu faktor yaitu perlakuan 5 dosis pemupukan (0% X, 50% X, 100% X, 150% X, dan 200% X di mana X merupakan rekomendasi dosis pupuk Ferads) dengan 5 ulangan. Pemberian pupuk N, P, dan K melalui irigasi tetes mampu meningkatkan tinggi tanaman, diameter batang, jumlah buah, dan bobot buah, serta mempercepat waktu antesis, waktu buah masak, dan growing heat summation. Dosis optimum pemupukan untuk tanaman terung varietas Yuvita F1 di tanah latosol tercapai pada taraf 137,74% dosis pada taraf P-tersedia sangat rendah (Mehlich 1) dan K-tersedia sedang (Mehlich 1). Dosis pupuk rekomendasi Ferads 100% dapat digunakan karena peningkatan dosis pupuk optimasi tidak meningkatkan produksi secara signifikan., Eggplant is widely cultivated in Indonesia but still has a relatively low national productivity. Productivity can be increased by providing the right nutrients amount through soil analysis and drip irrigation. The objective of this study was to find optimum fertilization recommendation dose for eggplant based on Mehlich 1 soil analysis test. The study was conducted on open field at Cikarawang, Experimental Farm, Bogor Agricultural University from June to November 2022. This study used a randomized complete block design (RCBD) with one factor that consisted of 5 doses of fertilization (0% X, 50% X, 100% X, 150% X, and 200% X where X is the recommended fertilizer dose from Ferads) with 5 replications. Application of N, P, and K fertilizers through drip irrigation can increased plant height, stem diameter, number of fruits, and fruit weight, as well as speed up anthesis time, fruit ripening time, and growing heat summation. The optimum dose of fertilizer for eggplant variety Yuvita F1 on latosol soil was reached at the level of 137.74% from recommended dose at very low available P (Mehlich 1) and medium available K (Mehlich 1). 100% Ferads fertilizer recommendation dose can be used because increased fertilizer optimum dose does not significantly produce higher yield.

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.
