Judul: Kontribusi Pengelolaan Agroforestri Terhadap Pendapatan Rumah Tangga Petani (Studi Kasus Di Desa Sukaluyu, Kecamatan Nanggung, Kabupaten Bogor, Jawa Barat)
Abstrak: Agroforestry is a land use system which combines woody plants with agricultural crops. Various previous researches concluded that agroforestry can improve the household income of farmers. Sukaluyu Village became one of the villages that make agroforestry as a source of their economy. The research was conducted to provide information regarding the contribution of agroforestry management to the farmer households as well as information about the agroforestry system adopted by local farmers. The results of research showed that farmers implement agroforestry system who combined trees with crops and trees with medicinal plants in which land management with agroforestry systems contribute to farmer household income was 68.60%.

Judul: Sistem Pengelolaan dan Kontribusi Kebun Campuran terhadap Pendapatan Rumah Tangga di Desa Sukadamai, Kecamatan Cicantayan, Kabupaten Sukabumi, Propinsi Jawa barat.
Abstrak: INTRODUCTION.Agroforestry is one of community forest design which is combining forestry and agriculture sector in a solid management. Agroforestry also the name that stands for land use system and technology where solid wood plant (trees, perdu, palm-trees, bamboo, etc) planting together with agriculture crops or animals for distinctive goals. Mixed planting is one of agroforestry construction that traditionally implement by society that also can divided into homegarden and garden. Mixed orchard management that organized by society around Gunung Walat Educational Forest (HPGW) including solid wood plants, fruits plants and agriculture crops. Wood potency with minimum quantity is belief will be a leading factor towards forest sustainability in HPGW. Management system identification and income contribution of farmers from mixed orchard need to ensure as strong consideration from policy that will be taken in order to establish society empowerment around HPGW. METHOD.Research is taken place at Sukadamai Village, Kecamatan Cicantayan, Kabupaten Sukabumi, West Java on April through Mai 2009 with two different plot samplings, which is farmers (35 people) and mixed orchard (4 plots) which grouped according to spacious of mixed orchard. Data is analyzed with qualitative method (data gathering, grouping, farmer’s characteristic identification and income contribution). After that, data is grouped and presented in a tabulation of numbers and images based on gathered data information. RESULTS.According to the research result, custom is the factors for farmers to manage their mixed orchards (31 %), technique of management (6 %), economy (60 %) and ecology (3 %). Mixed orchard management that farmers accomplished are; land management (weeding and land fertilizing); seed foundation; planting; breeding (land cleaning, fertilizing and cleaning of pest/disease); cutting; and marketing. The contribution of mixed orchard is Rp. 6.933.274/year (60,6 %) with the income of solid wood plant is Rp.1.289.464/year (16,3 %). The capital problems of mixed orchard management in Sukadamai Village are economy (70 %), establishment the organization (23 %), security (6 %), and pest/disease attack (1 %). CONCLUSIONS.Organization establishment and forwarding research about strategy to improving farmer’s wood income in Sukadamai Village.

Judul: Pembuatan dan Karakterisasi Film Litium Tantalat (LiTaO3) terhadap Variasi Suhu dan Waktu Annealing
Abstrak: Pada penelitian ini telah berhasil ditumbuhkan film LiTaO3 murni dengan ketebalan film berkisar antara 1,07-3,80 m di permukaan substrat Si (100) tipe-p. Penumbuhan film LiTaO3 dibuat dengan menggunakan metode chemical solution deposition (CSD) dengan teknik spin coating pada suhu annealing 800 oC, 850 oC, 900 oC selama 1 jam, 8 jam, 15 jam dan 22 jam. Karakterisasi arus-tegangan dan sifat optik dilakukan terhadap variasi suhu dan waktu annealing. Hasil karakterisasi arus-tegangan menunjukkan bahwa film LiTaO3 dapat dijadikan sebagai fotodioda dan sensor warna dilihat dari perbedaan nilai arus pada kondisi gelap-terang serta menggunakan filter merah, kuning dan hijau. Energi bandgap dari pengukuran karakterisasi optik berkisar antara 2,62-3,43 eV. Berdasarkan hasil karakterisasi arus-tegangan dan optik, film LiTaO3 setelah proses annealing pada suhu 800 oC selama 8 jam merupakan yang terbaik karena perbedaan arus terang-gelap paling besar yang disebabkan energi bandgap yang besar. Struktur kristal LiTaO3 setelah proses annealing pada suhu 800 oC selama 1 jam, 8 jam, 15 jam dan 22 jam adalah rhombohedral. Terbentuk pula puncak LiTaSiO5 yang memiliki struktur kristal monoclinic.
