Get PDFTitle : The Effect of Maturity Level of Empty Fruit Bunch Compost and Mulch from Palm Oil Waste to Tomato Productivity in Ultisol. This research was conducted to understand the effect of maturity level of empty fruit bunch compost and mulch from palm oil waste to tomato productivity in ultisol soil. This research used split plot design with mulch as main plot and maturity level of compost as sub plot. The mulch consists of four types: control, shell, fiber, and chopped of empty fruit bunch. The maturity level of compost consists of 5 levels: control, 4 weeks, 6 weeks, 8 weeks, and 10 weeks. Material used in this research was tomato Ratna variety. Compost of 8 weeks gave the lowest value of C/N ratio (35.16) than 4, 6, and 10 weeks. This compost also had the highest level of N-total, P and Mg: 1.34 %, 0.08 %, and 0.25 %. Compost containing the lowest C/N ratio and higher nutrition gave better vegetative growt. Compost of 8 weeks and fiber mulch provided the highest harvest weight and the highest number of fruit (436.56 gram and 16 fruits). Fruit number and fruit weight were lower than general tomato cultivation because of soil condition. Soil type was ultisol which had lower acidity level. The lower KTK level of this soil made distruption in nutrients uptake. Compost of 8 weeks could increase harvest weight 52.59 % higher than control and also could raise number of fruit 82.53 % higher than control. Shell mulch presented negative effect to growth and productivity of tomato.Penelitian ini dilakukan untuk mengetahui pengaruh tingkat kematangan kompos tandan kosong sawit dan penggunaan mulsa limbah padat kelapa sawit terhadap produksi tanaman tomat (Licopersicon esculentum Mill.) pada wilayah dengan tanah ultisol. Percobaan menggunakan rancangan petak terbagi (Split Plot Design) dengan mulsa sebagai petak utama dan kematangan kompos sebagai anak petak. Mulsa terdiri dari empat jenis yaitu tanpa mulsa, cangkang, fiber, dan cacahan TKS. Sedangkan tingkat kematangan kompos terdiri dari 5 taraf yaitu tanpa kompos, kompos 4 minggu, kompos 6 minggu, kompos 8 minggu dan kompos 10 minggu. Bahan yang digunakan adalah tomat (Lycipersicon esculentum Mill.) varietas Ratna. Kompos 8 minggu memberikan nilai C/N ratio terendah dibandingkan umur 4, 6, dan 10 minggu yaitu 35.16. Kompos umur 8 minggu menghasilkan nilai N-total, P, dan Mg tertinggi dibandingkan 3 kompos lainnya yaitu 1.34 %, 0.08 %, dan 0.25 %. Kompos dengan C/N rasio lebih rendah dan kandungan hara yang lebih tinggi memberikan pertumbuhan vegetatif tomat yang lebih baik dibandingkan kompos lainnya. Kompos 8 minggu dan mulsa fiber menghasilkan bobot panen dan jumlah buah terbanyak yaitu 436.56 gram dengan 16 buah. Jumlah dan bobot buah yang dihasilkan pada penelitian ini lebih rendah bila dibandingkan budidaya tomat pada umumnya karena kondisi tanah ultisol yang masam. Nilai KTK yang rendah mengakibatkan terganggunya penyerapan hara tanaman. Bila dibandingkan kontrol, penggunaan kompos 8 minggu meningkatkan bobot buah 52.59 % dan jumlah buah sebesar 82.53 %. Penggunaan mulsa cangkang menunjukan pengaruh negatif terhadap pertumbuhan dan produksi tanaman tomat

A study on optimization of dry land used the immobilized humic acid in seaweed as fertilizer supplement for maize plant (Zea Mays L) has been done in Bayan District North Lombok Regency Nusa Tenggara Barat Province. It was known that humic acid could increase availability and uptake of nutrient (N, P, K and Corganic) at maize plant in dry land of Bayan District. It was needed a modification technique that lower quantity of humic acid using without diminishing it’s utility, by immobilized humic acid in seaweed. Research design began with the preparation of immobilized humic acid in seaweed via entrapment technique (gel) and covalent bending (liquid). Immobilization result was characterized by infrared spectrophotometer. Agircultural land was mapped according to number of treatments, then each of them was analized physical and chemical properties before planting was done. Bayan agricultural land has sandy and loose texture, reddish brown colour, and neutral acidity (pH 6.97 at depth of 0-20 cm and a pH of 6.80 at depth of 21-40 cm). It has low availability nutrient of soil (Corganic, N, P, K) at 0-20 cm depth and 21-40 cm respectively are 2.950% and 2.860%, 0.067% and 0.076%, 0.001% and 0.004 %, 0.310% and 0.390%. While the cation exchange capacity value at a depth of 0-20 cm and 21-40 cm respectively are 20.95 and 22.16 me. Based on FTIR spectra, humic acid can be immobilized on seaweed as evidenced by absorption shift, especially in the carboxylic acid and amine groups. Humic acid was able to increase nutrient availability and uptake at maize plant through it’s ability in binding, adsorbing and exchanging nutrients. Application of humic acid in soil showed increasing of plant growth (plant height, weight and nutritional value of corn). Availability and uptake of N, P and K are highest in treatment 0.1% humic acid immobilized on seaweed 100 kg ha-1 (gel) and 0.1% humic acid immobilized in seaweed (liquid) with fertilizer 100% NPK dose.Suatu studi tentang optimalisasi lahan kering menggunakan asam humat terimmobil dalam rumput laut sebagai bahan pelengkap pupuk pada tanaman jagung di Kecamatan Bayan Kabupaten Lombok Utara provinsi Nusa Tenggara Barat telah dilakukan. Telah diketahui bahwa asam humat secara signifikan dapat meningkatkan ketersediaan dan pengambilan nutrien (N,P,K, dan C-organik) pada tanaman jagung di lahan kering Kecamatan Bayan. Diperlukan suatu teknik modifikasi yang dapat mengurangi jumlah pemakaian asam humat tanpa mengurangi manfaatnya yaitu dengan mengimobilisasi asam humat pada rumput laut. Rancangan penelitian dimulai dengan preparasi asam humat terimobilisasi pada rumput laut melalui teknik entrapment (gel) dan covalent bending (liquid). Hasil imobilisasi dikarakterisasi menggunakan spektrofotometer IR. Lahan pertanian dipetakan sesuai dengan jumlah perlakuan kemudian masing-masing pemetaan lahan dianalisis sifat fisik dan kimianya sebelum penanaman jagung dilakukan. Lahan pertanian kec. Bayan memiliki sifat fisik bertekstur pasir, struktur lepas dan berwarna coklat kemerahan dengan derajat keasaman netral (pH 6,97 pada kedalaman 0–20 cm dan pH 6,80 pada kedalaman 21–40 cm). Selain itu tanah ini mempunyai kandungan hara (C organik, N, P, K) tersediakan rendah pada kedalaman 0–20 cm dan 21–40 cm berturut-turut yaitu 2,950% dan 2,860%; 0,067% dan 0,076%; 0,001% dan 0,004%; 0,310% dan 0,390%. Sedangkan nilai KTK pada kedalaman 0–20 cm dan 21–40 cm berturut-turut yaitu 20,95 dan 22,16 me%. Berdasarkan hasil spektra FTIR, asam humat dapat diimmobilisasikan pada rumput laut yang dibuktikan dengan adanya pergeseran serapan terutama pada gugus asam karboksilat dan amina. Asam humat mampu meningkatkan ketersediaan dan pengambilan unsur hara bagi tanaman melalui kemampuannya mengikat, menjerap dan mempertukarkan unsur hara. Ketersediaan dan pengambilan N, P dan K tertinggi ditemukan pada perlakuan 0,1% asam humat terimobilisasi pada rumput laut 100 kg ha-1 (gel) dan 0,1% asam humat terimobilisasi pada rumput laut (liquid) bersama pupuk NPK dosis 100%

Fenomena of decreasing water supply and increasing water demand occurred at Konaweha watershed. Konaweha watershed shed is a priority watershed in Southeast Sulawesi Province due to its crucial function. Land use changes were suspected to be the cause of decreasing water supply. One effect of this condition was maximum discharge increase and minimum discharge decrease of Konaweha River resulted in water deficit. Research objectives were (1) to evaluate the effect of land use changes on hydrologic condition of Konaweha watershed; (2) to evaluate the water supply and water demand as well as supply and demand water balance at Konaweha watershed, and (3) to formulate land use alternatives and management policy of Konaweha watershed. This research had been conducted at Konaweha watershed for 10 months e.g. from June 2009 to March 2010. The average declining of forest width during 1991‐1999 was 1.25 percent/year, 2001‐2005 was 0.52 percent/year and 2006‐2011 was 0.90 percent/year. In the same time the availability of minimum discharge as a water supply was decrease. There was no deficit on annual water supply until 2050 but monthly distribution of hydrograph caused water deficit in September started from 2016. Proportion of maintenance cost for watershed function at Kendari Municipality was 35 percent while at the District of Konawe, South Konawe and Kolaka were 28 percent, 15 percent, and 22 percent respectively from total economic value of water at Konaweha watershed.
