Pertumbuhan Tunas Ubi Kayu (Manihot Esculenta Crantz.) Genotipe Jame-jame secara In Vitro

The continuous supply of true-to-type seedling through in vitro technique is very important for cassava (Manihot esculenta Crantz.) as the demand for seedlings is increasing. The research consisted of two experiments and they were conducted from February 2013 to February 2014. The first experiment was in vitro shoot multiplication to evaluate the effect of culture medium and single node position on growth and shoot multiplication of cassava Jame-jame genotype. This experiment was arranged in a randomized complete block design with two factors and four replications. The first factor was culture medium (MS0 and MSB3) and the second factor was single node positions used as explant (basal, middle, and top section of the stem). The result showed that middle section of the stem cultured on MS0 medium had the highest shoot height, number of leaves, and number of nodes. The second experiment was the acclimatization to evaluate the effect of culture period on the success of the acclimatization. This experiment was arranged in a completely randomized design with culture period prior to acclimatization as treatment. The results showed that seedlings from period of 12 and 24 weeks after culture showed higher survival rates (80%) than seedling from period of 36 and 48 weeks after culture (50 and 40%). Culture period prior to acclimatization had no significant effect on plant height and number of leaves

POTENSI KALIANDRA (Calliandra calothyrsus) DAN GAMAL (Gliricidia sp.) DI DAERAH ISTIMEWA YOGYAKARTA UNTUK PENGEMBANGAN PELET KAYU

Negara-negara di dunia, khususnya Eropa, Jepang, Korea Selatan dan China, mulai beralih ke penggunaan energi terbarukan yaitu pelet kayu. Indonesia dengan iklim tropis, keanekaragaman jenis tanaman dan ketersediaan lahan untuk pengembangan sumber energi ini, berpeluang menjadi salah satu produsen utama pelet kayu, baik untuk memenuhi permintaan nasional atau internasional. Daerah Istimewa (DI) Yogyakarta merupakan salah satu provinsi di Indonesia yang memiliki hutan rakyat dan berpeluang untuk dikembangkan sebagai produsen pelet kayu. Penelitian ini bertujuan untuk memperoleh informasi awal tentang jenis tanaman kayu potensial di DI Yogyakarta. Pengambilan data dilakukan dengan studi pustaka dan survey kepada Kelompok Tani Hutan (KTH) di Kabupaten Bantul (22 KTH), Gunungkidul (15 KTH), Kulonprogo (15 KTH) dan Sleman (19 KTH). Cabang dan ranting kering merupakan sumber bahan bakar kayu utama bagi KTH di DI Yogyakarta, tanpa melihat jenis tanamannya. Jenis kaliandra (Calliandra calothyrsus) dan gamal (Gliricidia sp.) sebagai jenis potensial untuk pelet kayu ditanam sebagai sumber hijauan makanan ternak, sumber nektar untuk peternakan lebah madu dan untuk konservasi tanah. Kedua jenis ini ditanam sebagai tanaman tepi di pinggir lahan, diantara tanaman pertanian dan atau tanaman berkayu, bukan sebagai tanaman utama. Jumlah yang ditanam sangat variatif berkisar antara 0 - 2000 pohon kaliandra/ha dan 0 - 3000 pohon gamal/ha. Berdasarkan hasil tersebut diketahui bahwa jenis potensial untuk produksi pelet kayu, kaliandra dan gamal sudah ditanam di 4 kabupaten tersebut. Namun penanaman kedua jenis tersebut perlu dikembangkan agar dapat mendukung produksi pelet kayu

Managing Oil Palm Plantations More Sustainably: Large-Scale Experiments Within the Biodiversity and Ecosystem Function in Tropical Agriculture (BEFTA) Programme

Conversion of tropical forest to agriculture results in reduced habitat heterogeneity, and associated declines in biodiversity and ecosystem functions. Management strategies to increase biodiversity in agricultural landscapes have therefore often focused on increasing habitat complexity; however, the large-scale, long-term ecological experiments that are needed to test the effects of these strategies are rare in tropical systems. Oil palm (Elaeis guineensis Jacq.)—one of the most widespread and important tropical crops—offers substantial potential for developing wildlife-friendly management strategies because of its long rotation cycles and tree-like structure. Although there is awareness of the need to increase sustainability, practical options for how best to manage oil palm plantations, for benefits to both the environment and crop productivity, have received little research attention. In this paper we introduce the Biodiversity and Ecosystem Function in Tropical Agriculture (BEFTA) Programme: a long-term research collaboration between academia and industry in Sumatra, Indonesia. The BEFTA Programme aims to better understand the oil palm agroecosystem and test sustainability strategies. We hypothesise that adjustments to oil palm management could increase structural complexity, stabilise microclimate, and reduce reliance on chemical inputs, thereby helping to improve levels of biodiversity and ecosystem functions. The Programme has established four major components: (1) assessing variability within the plantation under business-as-usual conditions; (2) the BEFTA Understory Vegetation Project, which tests the effects of varying herbicide regimes; (3) the Riparian Ecosystem Restoration in Tropical Agriculture (RERTA) Project, which tests strategies for restoring riparian habitat; and (4) support for additional collaborative projects within the Programme landscape. Across all projects, we are measuring environmental conditions, biodiversity, and ecosystem functions. We also measure oil palm yield and production costs, in order to assess whether suggested sustainability strategies are feasible from an agronomic perspective. Early results show that oil palm plantation habitat is more variable than might be expected from a monoculture crop, and that everyday vegetation management decisions have significant impacts on habitat structure. The BEFTA Programme highlights the value of large-scale collaborative projects for understanding tropical agricultural systems, and offers a highly valuable experimental set-up for improving our understanding of practices to manage oil palm more sustainably

Respon Pupuk Guano dan Pemangkasan terhadap Hasil Jagung Manis (Zea Mays Saccharata L.)

Penelitian ini bertujuan untuk mengetahui respon pupuk guano dan pemangkasan serta interaksinya terhadap hasil jagung manis (Zea mays saccharata L.). Penelitian ini dilaksanakan pada bulan Mei sampai Juli 2019 sejak persiapan sampai pengambilan data terakhir. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan analisis faktorial 4 x 3 dengan ulangan sebanyak tiga kali. Faktor pertama adalah pemangkasan daun (P) yang terdiri atas 4 taraf, yaitu p0 = tanpa perlakuan (kontrol), p1 = 1 helai daun, p2 = 2 helai daun, dan p3 = 3 helai daun. Faktor kedua adalah aplikasi pupuk guano yang terdiri atas 3 taraf yaitu g0 = tanpa pupuk (kontrol), g1 =  20 ton ha-1 (12 kg petak -1), dan g2 = 40 ton ha-1 (24 kg petak -1). Hasil penelitian menunjukkan bahwa perlakuan pupuk guano dan pemangkasan daun serta interaksinya memberikan pengaruh yang tidak nyata terhadap semua parameter pengamatan. Hasil tertinggi rata-rata bobot tongkol berkelobot per hektar untuk perlakuan pupuk guano, pemangkasan, dan interaksinya berturut-turut yaitu pada perlakuan g0 (28,55 ton ha-1), p1 (29,83 ton ha-1), g0p0 dan g1p1 (32,40 ton ha-1). Sedangkan hasil terendah pada perlakuan g2 (26,62 ton ha-1), p0 dan p3 (26,23 ton ha-1), dan  g1p3 (23,14 ton ha-1)

Meanwhile, the lowest intensity of plant damage was obtained in treatment b2 (40 g Beauveria bassiana L-1 water) which was 13.33%, p2 (42 ml LOF L-1 water) was 15.56%, and treatment combination b1p2 (20 g Beauveria bassiana L-1 water and 42 ml LOF L-1 water) was 8.33%

PORTOFOLIO DAN INVESTASI

Portofolio adalah istilah yang cukup familiar bagi mereka yang terjun di bidang investasi. Portofolio sendiri erat kaitannya dengan diversifikasi investasi. Istilah Portofolio Investasi adalah sekumpulan investasi yang dimiliki oleh suatu institusi ataupun perorangan. Bentuknya bisa bermacam-macam, seperti obligasi, reksa dana, properti, saham, dan instrumen investasi lainnya. Bagi orang-orang yang melakukan investasi saham, ada pula istilah Portofolio Saham, yaitu kumpulan aset investasi yang berbentuk saham. Dalam portofolio, seorang investor dapat melakukan diversifikasi pada berbagai produk investasi untuk menghasilkan return yang optimal & meminimalkan risiko. Hal ini sesuai dengan nasihat untuk tidak menaruh semua telur dalam satu keranjang, supaya semua telur tidak pecah jika keranjang tersebut jatuh. Dengan diversifikasi, risiko yang ditanggung dalam sebuah investasi dapat berkurang karena seluruh uang tidak dimasukkan ke satu instrumen investasi saja. Semakin banyak aktiva (keranjang), maka risikonya semakin rendah. Adapun aset yang tersimpan di dalamnya dapat berupa real estate, karya seni, perhiasan maupun bentuk penanaman modal lain yang bisa mendatangkan keuntungan di masa mendatang. Berdasarkan hal tersebut maka, buku ini menyajikan segala yang dibutuhkan oleh para pengelola perusahaan dalam menjalankan roda perputaran perusahaan agar dapat menciptakan kualitas dan kuantitas prusahaan yang baik. Oleh sebab itu buku ini hadir kehadapan sidang pembaca sebagai bagian dari upaya diskusi sekaligus dalam rangka melengkapi khazanah keilmuan dibidang Analisis Investasi, sehingga buku ini sangat cocok untuk dijadikan bahan acuan bagi kalangan intelektual dilingkungan perguru tinggi ataupun praktisi yang berkecimpung langsung dibidang Analisis Investasi
