Judul: Perbaikan Pertumbuhan Rhizophora mucronata Lamk. melalui Pemupukan dengan Teknik Semprot di Kawasan Jalur Hijau Tol Sedyatmo Angke Kapuk, DKI Jakarta
Abstrak: Pemupukan merupakan salah satu perlakuan silvikultur untuk meningkatkan pertumbuhan tanaman. Tujuan dari penelitian ini adalah mengkaji pengaruh pemberian pupuk daun dengan teknik semprot terhadap pertumbuhan tanaman bakau (R. mucronata Lamk.). Pemberian pupuk dan pengukuran parameter dilakukan satu kali dalam satu minggu dengan lama pengamatan 12 minggu. Parameter yang digunakan yaitu pertambahan dimensi diameter batang dan tinggi tanaman, serta kandungan unsur hara sebelum dan sesudah pemupukan. Perlakuan yang diberikan digolongkan berdasarkan perbedaan konsentrasi pupuk dan kontrol. Hasil sidik ragam menunjukkan bahwa pemberian pupuk tidak berpengaruh signifikan terhadap pertumbuhan diameter batang dan tinggi tanaman bakau. Secara umum kandungan unsur hara daun tidak jauh berbeda baik sebelum maupun sesudah pemupukan. Hal tersebut menggambarkan bahwa pemberian pupuk daun selama 12 minggu pada berbagai konsentrasi yang dicobakan tidak berpengaruh signifikan terhadap pertumbuhan tanaman bakau.

Judul: Pertumbuhan Bakau Merah (Rhizophora mucronata) di Persemaian Mangrove Desa Muara, Kecamatan Teluk Naga, Kabupaten Tangerang
Abstrak: The success of mangrove rehabilitations are influenced by various factors which one of them is the availability of seedling stocks over time. The knowledge about growth process and development of plants which will be used as seedlings are several factors of success of nursery development. Red mangrove (Rhizophora mucronata) is one species of plants which grows in mangrove forest. The conservation of this species is very important because its habitat is at the central zone of mangrove formation and has high reproduction over time so it can be easier to do rehabilitation. The aim of this research is to get the information about R.mucronata growth and development to get better cultivation technique. The treatments were planting of propagul that had pieces of fruit and planting of propagul without pieces of fruit. Based on this research, the planting of propagul without pieces of fruit gave significant effect toward the heigth and length of red mangrove (R.mucronata) propagules development.

Abstrak: Graphology or handwriting analysis is a method of identifying, analysing, evaluating, and understanding personality through the strokes and patterns revealed by handwriting. People who can analyze handwriting called graphologist. Graphologist can have a subjective assesment. Different graphologist can analyze the same handwriting but give different results. In addition, the accuracy of handwriting analysis depend on the graphologists ability. A system that can recognize handwrititng patterns is required to overcome these problems. Identification system which is implemented in this research uses Backpropagation Neural Network (BPNN). This research used 135 images of letter a and 150 images of letter t. This research is divided into three parts which are determining optimal combination of BPNN parameter, identifying personality based on letter a, and identifying personality based on letter t then classifies them into one of three character classes available. The results of this research is that the system has 98.15% accuracy for letter a and 73.33% for letter t. The result shows that Backpropagation Neural Network can be used to classify the personality
