Lindi sampah kota memiliki kandungan unsur hara makro dan mikro essensial bagi tanaman. Namun, kandungan senyawa pada lindi belum memenuhi standar sebagai pupuk organik cair, sehingga perlu upaya pemekatan agar lebih berdayaguna. Penelitian ini bertujuan untuk mengetahui pengaruh peningkatan dosis pupuk granular berbahan dasar lindi sampah kota terhadap kandungan nitrogen pada media pembibitan lada (Piper nigrum L.). Penelitian disusun menggunakan Rancangan Acak Kelompok Lengkap (RAKL). Perlakuan terdiri dari lima taraf dosis pupuk granular lindi sampah kota yaitu: tanpa pupuk (P0); 10 gram/polibag (P1); 20 gram/polibag (P2); 30 gram/polibag (P3); dan 40 gram/polibag (P4). Penelitian dibagi lima kelompok yang sekaligus menjadi ulangan, sehingga terdiri dari 25 satuan percobaan dan setiap satuan percobaan terdiri dari lima media pembibitan tanaman lada. Untuk mengetahui pengaruh pelakuan dilakukan analisis kesamaan ragam data dengan uji Bartlett dan keaditifan data dengan uji Tukey. Data dianalisis dengan analisis ragam dan dilanjutkan dengan uji Beda Nyata Terkecil, Perbandingan Ortogonal, dan Ortogonal Polinomial pada taraf pengujian 5%. Hasil penelitian menunjukan bahwa pupuk granular berbahan dasar Lindi sampah kota mampu meningkatkan kandungan nitrogen dalam media pembibitan tanaman lada. Dosis pupuk granular lindi sampah kota 20 g/polibag merupakan dosis terbaik dengan kandungan N 0,35%. Namun kandungan N media pembibitan lada tanpa pupuk tidak berbeda nyata dengan dosis 10, 30, dan 40 g/polibag. Peningkatan dosis pupuk granular lindi sampah kota mampu meningkatkan kandungan nitrogen mengikuti pola kuadratik, dengan persamaan y = -0,00009x2 +0,0035x +0,2828; R2= 0,3106.

The last nutrient management review of black pepper was done in 1968. There is, therefore, a need to develop new technology to improve pepper production and transfer that technology to production site. This experiment was carried out to study the effect of newly developed biochemical fertilizer on some physiological characteristics, yield and soil fertility of pepper. The treatment consisted of T1 (BS): chemical fertilizer (N:12%, P:12%, K:17%); T2 (BK1): biochemical fertilizer F1 N:15%, P:5%, K:14) and T3 (BK2): biochemical fertilizer F2 (N:13%, P:4%, K:12). The biochemical fertilizer F1 out-yielded chemical and biochemical fertilizer F2 by 75.38% and 16.45% respectively with the higher yield being associated with various phonotypical alterations, which are reported here. Significant measureable changes were observed in physiological processes and plant characteristics, such as large leaf area index, more chlorophyll content and high photosynthesis rate coupled with lower transpiration rate in biochemical fertilizer F1(BK1) treatment compared with other treatment. The high fertility level in biochemical fertilizer F1 and biochemical fertilizer F2 (BK2) reflected the important of organic material in improving soil quality. In conclusion, the achieve high growth performance and yield in pepper, chemical fertilizer alone is insufficient whilst combination of organic and inorganic fertilizer with balance nutrient content gave a significant increase in yield and growth of pepper.

Research studies were carried out to evaluate insecticidal action of two plant products and a synthetic insecticide on a major stored-product insect, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae). The plant species studied were, Piper nigrum and Eucalyptus camaldulensis, whereas methoprene used as synthetic insecticide. Two formulations viz., powder and ethanol extract of each plant and four concentrations (5ppm, 10ppm, 15ppm and 20 ppm) of methoprene were tested. Repellency was tested using the filter paper test whereas mortality, weight loss protection and anti-feedant potential of all treatments was evaluated by using whole maize grains. Our results were highly significant as compared to control however; P. nigrum was more effective as compared to E. camaldulensis. The investigation of cumulative effects of botanical and synthetic insecticide and isolation of active ingredients of botanicals are further issues to be investigated for their inclusion in. I. P.

Oil Performance

Vietnam is the world's leading country in growing and producing pepper trees. In this study, we attempted the optimization of white pepper essential oil extraction. The obtained oil was then subject to determination of constituent composition via GC-MS method. The essential oil performance achieved 3.6% by hydro-distillation process with optimal conditions (25 grams of fresh pepper, size 18, 120 minutes extraction, 130°C). A total of 23 volatile constituents were identified from the white pepper essential oil, with the major components being 27.4% of Limonene, 3-Carene 22,928%, Sabinene 17,622%, β-pinene 10.068%, α-Pinene 5.426%.
