Penelitian ini bertujuan untuk mengetahui: aplikasi asap cair tempurung kelapa dan pemberian pupuk NPK yang mampu menekan pertumbuhan gulma, menurunkan intensitas serangan hama dan penyakit, serta mendukung hasil padi gogo yang optimal. Penelitian ini dilaksanakan di kebun Balai Benih Palawija Kalicacing yang berada di Desa Kalimandi, Kecamatan Klampok, Kabupaten Banjarnegara pada bulan April hingga Juli 2017. Rancangan yang digunakan adalah rancangan petak terbagi (Split Plot) dengan petak utama pupuk NPK: 1) P1 (dosis NPK 50% rekomendasi), 2) P2 (dosis NPK 100% rekomendasi), dan anak petak yaitu asap cair tempurung kelapa: 1) A0 (tanpa aplikasi asap cair tempurung kelapa), 2) A1 (asap cair tempurung kelapa 5%), 3) A2 (asap cair tempurung kelapa 2,5%), 4) A3 (asap cair tempurung kelapa 1,67%), 5) A4 (asap cair tempurung kelapa 1,25%), dan 6) A5 (asap cair tempurung kelapa 1%). Kombinasi perlakuan yang diperoleh sebanyak 12 unit dan diulang tiga kali sehingga ada 36 unit percobaan. Variabel yang diamati antara lain: Summed Dominance Ratio (SDR), indeks kesamaan gulma, intensitas serangan hama dan penyakit, jumlah malai per rumpun (helai), jumlah gabah per rumpun (butir), persentase gabah isi per rumpun (%), bobot gabah per rumpun (gram), bobot gabah 1000 biji (gram), bobot gabah per petak efektif (kilogram), dan bobot gabah per hektar per hektar (ton/ha). Hasil penelitian menunjukan bahwa pemberian pupuk NPK dan aplikasi asap cair tempurung kelapa belum mampu menekan pertumbuhan gulma, intensitas serangan penyakit 40 hst dan 70 hst serta belum mampu meningkatkan jumlah malai, jumlah gabah per rumpun, bobot gabah per rumpun, bobot gabah petak efektif dan bobot gabah per hektar (ton/ha).

The purpose of this research is to know: the effect of application coconut shell liquid smoke and dosage of NPK fertilizer that are capable of compressing weed growth, pest attack and disease intensity, and optimal rice yield. The research was conducted in Palawija Kalicacing Seed Garden located in Kalimandi Village, Klampok District, Banjarnegara Regency from April to July 2017. Reserach method that used was Split Plot with the main plot of NPK fertilizer: P1 (dosage of NPK 50% recommendation); 2) P2 (dosage of NPK 100% recommendation 100%); and sub plot of coconut shell liquid smoke 1) A0 (without coconut shell liquid smoke application); 2) A1 (coconut shell liquid smoke 5%); 3) A2 (coconut shell liquid smoke 2,5%); 4) A3 (coconut shell liquid smoke 1,67%); 5) A4 (coconut shell liquid smoke 1,25%); and 6) A5 (coconut shell liquid smoke 1%). The combined treatment obtained was 12 units and 3 times repetition so that there were 36 experimental units. The variables observed were: Summed Dominance Ratio (SDR), index of weeds, pest attack and disease intensity, amount of panicles (blade), amount of productive panicles per clumps (g), grain weight per clumps (g), content of grain presentation (%), weight of 1000 seeds (g), weight of effective grain plot (kg), and weight of grain per hectare (ton/ha). The results from this research show that application of NPK fertilizer and coconut shell liquid smoke had not been able to compress the disease intensity of 40 and 70 one day after planting and have not been able to increase the number amount of panicles (blade), amount of productive panicles per clumps (g), grain weight per clumps (g), content of grain presentation (%), weight of effective grain plot (kg), and weight of grain per hectare (ton/ha).
