Abstract

Elephant grass (Pannisetum purpureum) can grow in various types of land conditions and produces and is resistant to environmental stress. The predominant sand tin tailing conditions and poor nutrients cause limited plant growth above them. This research tested some kind of fertilizer treatment on sand tailing media after tin addition by using elephant grass plants. The results showed that the type of fertilizer had significant effect on the specific leaf area variant, the ratio of leaf area and the leaf weight ratio. Overall growth were greatly depressed on the 100% tailings treatment. Lime applied in conjunction with NPK fertilizer was not show the total leaf weight that was different from the addition of NPK alone. NPK fertilizers better influence the growth of elephant leaves in tin tailings than organic fertilizers. The best treatment was obtained on organic fertilization with NPK inorganic fertilization. The association of total dry weight of elephant grass with specific area of elephant grass leaf was only visible in organic fertilization treatment together with NPK inorganic fertilizer. In the best condition of elephant grass growth, the specific leaf area had a significant role to increase the total weight of the plant with the value of r2 = 0.864 or LDS will affect the total dry weight of elephant grass in the tailings medium with the addition of organic and inorganic materials NPK of 86.4 percent the remaining 13.6% increase in total dry weight was influenced by factors other than specific leaf area.

Abstract

The existence of tree vegetation planted in coffee plantations as shade trees is believed to have a positive influence on the growth and production of coffee plants. This study aims to analyze the diversity of coffee plant vegetation in three age classes planted inside and outside protected forest areas included in the administrative area of North Dempo and Central Dempo Districts, Pagar Alam City, South Sumatra Province. The results of observations and calculations of Value IVI found that Albizia sumatrana was the dominant species in all coffee plantations at various age levels. The IVI values of Albazia Sumatrana in coffee plants aged < 5 years were 157.32 (inside PF) and 720.92 (outside PF), in coffee plants aged < 10 years, were 84.30 (inside PF) and 155.51 (outside PF), while in coffee aged > 10 years is 75.46 (inside PF) and 95.92 (outside PF). Assessment using the Shanon Index and Simpon Index showed the same results; coffee plantations at all age levels had a moderate diversity index, except for vegetation in coffee plantations aged < 5 years which were outside protected forest areas and had low diversity index values. Through the availability of this information, it is hoped that it will be used as initial information for selecting vegetation types that will be used to support restoration activities in areas around protected forests.

Abstract

Masyarakat Desa Tanjung Pering tidak memiliki usaha ternak ayam, sehingga kebutuhan pupuk organik kotoran ayam yang dibutuhkan untuk bertanam sayuran dipasok dari luar desa dengan harga yang cukup tinggi, akibatnya biaya produksi sangat tinggi. Disisi lain di Desa Tanjung Pering banyak terdapat tanaman pisang. Faktor-faktor tersebut menimbulkan persoalan yang dihadapi oleh masyarakat desa sebagai mitra yaitu 1] Mitra tidak memiliki sumber pupuk organik, dan 2] Belum ada pembinaan yang berkesinambungan cara membuat pupuk organik berbahan dasar tanaman dan aplikasinya pada budi daya sayuran. Tujuan kegiatan adalah melatih masyarakat tani di Desa Tanjung Pering untuk mampu membuat pupuk organik berbahan tanaman seperti batang pisang, sehingga dapat menyediakan sendiri pupuk organik. Manfaat kegiatan adalah 1] Masyarakat memahami cara membuat pupuk organik berbahan dasar batang pisang, 2] Masyarakat mampu mengaplikasikan pupuk organik berbahan tanaman pada budidaya Sayuran dan 3] Dapat mengurangi biaya produksi. Hasil kegiatan yang telah dilakukan masyarakat sangat antusias mengikuti kegiatan pengabdian pelatihan pembuatan kompos, dan hasil percobaan penggunaan kompos batang pisang sebagai campuran media tanam menunjukkan bahwa campuran media tanam yang tepat dari tanah, pupuk kendang dan kompos menghasilkan pertumbuhan beberapa tanaman sayuran yang lebih baik.
