Abstrak: Garis-Garis Besar Haluan Negara (GBHN, 1993), menyatakan bahwa pertanian dalam arti yang luas perlu terus dikembangkan agar makin maju dan efisien dan diarahkan untuk meningkatkan kuantitas dan kualitas produksi serta keanekaragaman hasil pertanian, melalui usaha diversifikasi, intensifikasi, ekstensifikasi dan rehabilitasi pertanian dengan memanfaatkan ilmu pengetahuan dan teknologi. Disebutkan pula bahwa pembangunan kehutanan terus ditingkatkan dan diarahkan untuk menjamin kelangsungan penyediaan dan perluasan keanekaragaman hasil hutan bagi pembangunan industri, perluasan lapangan kerja dan kesempatan usaha, sumber pendapatan negara dan pemicu pembangunan daerah serta menjaga fungsi-nya sebagai salah satu penentu ekosistem untuk memelihara tata air, plasma nutfah, kesuburan tanah dan iklim. Pembangunan pertanian dan kehutanan berjalan selaras dan saling mendukung serta sangat berperan besar dalam penyediaan lapangan kerja. Pada kedua bidang tersebut diupayakan adanya peningkatan keanekaragaman hasil untuk pemenuhan kebutuhan masyarakat. Perpaduan antara pertanian dan kehutanan dikenal dengan istilah Agroforestry.

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: Fullerenes C20, C28, C60, C78, C84 Molecular Docking Study with Spike Glycoprotein SARS-CoV-2
Abstrak: Spike glycoprotein pada SARS-CoV-2 berperan penting dalam proses infeksi virus. Carbon based nanomaterials memiliki banyak alotrop seperti graphene, carbon dots, dan fullerene yang memiliki peran dan interaksi tertentu pada spike glycoprotein. Penelitian ini menggunakan fullerene sebagai ligan dan spike glycoprotein SARS-CoV-2 sebagai reseptor dan mempelajarinya dengan metode molecular docking. Hasil docking didapatkan nilai energi ikat paling negatif dari semua ligan yaitu fullerene C84 dengan nilai -15,9 kcal/mol. Jenis interaksi yang didapatkan yaitu interaksi hidrofobik. Variasi ukuran fullerene mempengaruhi interaksi dan potensi fullerene dalam menginhibisi spike glycoprotein. Berdasarkan targeted docking presentase moda pengikatan sisi aktif reseptor pada fullerene C20 dan C28 sebesar 0%, fullerene C60 sebesar 85%, fullerene C78 dan C84 sebesar 100%. Semakin besar ukuran fullerene maka semakin kuat ikatannya dan potensinya dalam memblok sisi aktif pengikatan ACE2., The spike glycoprotein in SARS-CoV-2 plays an important role in the viral infection process. Carbon based nanomaterials have many allotropes such as graphene, carbon dots, and fullerenes that have specific roles and interactions in spike glycoproteins. This research used fullerenes as ligands and spike glycoprotein SARS-CoV-2 as receptors and studied them by molecular docking method. The docking results obtained the most negative binding energy value of all ligands, namely fullerene C84 with a value of -15,9 kcal/mol. The type of interaction obtained is a hydrophobic interaction. Variations in the size of fullerenes affected the interaction and potential of fullerenes in inhibiting spike glycoproteins. Based on targeted docking, the percentage of the active site binding mode of the receptor on C20 and C28 fullerenes are 0%, C60 fullerenes are 85%, C78 and C84 fullerenes are 100%. The larger the size of the fullerene, the stronger the bond and its potential to block the active site of ACE2 binding.
