Abstract

Solid waste management is an old problem in urban areas.  High population growth rates have caused the increasing amount of wastes generated. One of the efforts to solve the problem is to recycle the organic wastes by composting. The purpose of this research was to find out the influence of effective inoculants PROMI and EM4 on decomposition rate and compost quality from municipal waste in Ambon. This research used a Completely Randomized Design (CRD) in single factor experiment using 2 effective inoculants, i.e. PROMI (no Promi = P0, 24 gr Promi/10 kg organic waste = P1, 48 gr Promi/10 kg organic waste = P2) and EM4 (no EM4 = E0, 150 ml EM4/10 kg organic waste = E1, 300 ml EM4/10 kg organic waste = E2). The treatments consisted of the 2 types of inoculants with 3 dosages of each, and 3 replications. The result showed that the addition of effective inoculant EM4 with a dosage of 300 ml per 10 kg organic waste (E2) was more effective compared to the other treatments in accelerating the decomposition rate in 28 days. This was supported by decomposition rate indicators, such as compost physical characteristics, C/N ratio (11.56), and the increased compost quality, such as pH (8.03), Nitrogen (2.91%), Phosphorus (141.33 mg per 100g P2O5), Potassium (553.67 mg per100g K2O). This compost was in accordance to Indonesia National Standard (INS) or Standar Nasional Indonesia (SNI) of organic manure No. 19-7030-2004.

Abstract

Land degradation on the upper stream area in Ambon island has reduced the availability of fresh water for the peoples. An available fresh water supports only 19.14% of total population.  This research was carried out to solve the problem of water resources shortage in Ambon city which is sourced from Batugantung.  The objectives of this research were to evaluate the impact of land use changes on the income, hydrological characteristics, erosion and sedimentation in Batugantung watershed. The result of this research showed that the increasing density and coverage of vegetation can increase the sustainability of land and water resources.  The increasing vegetation density in agroforestry land use can imitate the role of forest in sustaining watershed hydrological function, decreasing runoff, controlling erosion as well as  increasing farmer’s  income.  By keeping  at least 30% forest in dusun land use management in  Batugantung watershed, it can sustain water yield about 75.66 liters.s-1, decrease erosion to 27.62 ton.year-1, and increase farmers income up to Rp. 15.64 million ha-1.year-1.   By applying  the result of this research to other watersheds in Ambon island, the availability water resources will be about 13.07 x 105 m3.day-1. This amount of water resources can fulfill present total requirement of fresh water for  380 thousand peoples in Ambon island which is only  6.08 x 104  m3.day-1.

Abstract

Jagung putih memiliki kemampuan untuk beradaptasi pada kondisi lingkungan yang sub optimum serta merupakan makanan pokok bagi masyarakat di kabupaten Maluku Barat Daya. Tujuan dari penelitian ini adalah untuk mengetahui (1) kemampuan jagung putih beradaptasi jika ditanam di luar habitat aslinya terutama pada tanah regosol dan kambisol; (2) dosis pupuk organik ela sagu terbaik bagi pertumbuhan dan produksi jagung putih yang ditanam pada tanah regosol dan kambisol; (3) dosis pupuk dan jenis tanah yang menghasilkan pertumbuhan dan produksi jagung tertinggi.. Percobaan faktorial ini menggunakan Rancangan Kelompok Lengkap Teracak terdiri dari dua faktor dan tiga ulangan. Faktor pertama adalah jenis tanah (A), yaitu rogosol (A1) dan kambisol (A2). Faktor kedua adalah dosis pupuk organik ela sagu (B), yaitu tanpa pemberian pupuk (B0); 7,5 t ha-1, (B1); 10 t ha-1. (B2); 12,5 t ha-1 (B3); 15 t ha-1 (B4). Peubah yang diamati antara lain tinggi tanaman, jumlah dan luas daun; panjang, diamater, dan berat tongkol per tanaman, berat pipilan kering per petak, serapan hara N, P, K. Data dianalisis menggunakan analisis varian taraf 5% dan uji berganda Duncan. Hasil penelitian menunjukkan bahwa semua peubah dari tanaman yang diberi 15 t ha -1 kompos baik pada tanah regosol maupun kambisol lebih tinggi dibandingkan dengan dosis lainnya. 15 t ha-1 kompos pada tanah regosol menghasilkan N, P, K tertinggi yang diindikasikan oleh pertumbuhan dan produksi jagung putih tertinggi dibanding dengan kambisol. Jagung putih lebih mampu beradaptasi pada tanah regosol
