Abstract

The pepper plant (Piper nigrum L.) is Indonesia's leading spice commodity. Bangka Belitung as a producing center still has problems in cultivation, including nutrient availability. Nutrients N, P and K are macro elements that really determine the growth of plants, including pepper. This research aims to identify the status of macro nutrients, namely N, P and K in pepper plants in Simpang Katis Village, Central Bangka Regency, through observing growth status, leaf visuals, nutrient analysis and plant tissue analysis. This research was carried out in Simpang Katis Village, Central Bangka Regency in July-September 2023. The experimental method used in this research was observation and laboratory analysis methods. The results of the observation data show that NPK nutrients in land with very good growth criteria have N-total of 0.22%, P2O5 available is; 383.2 mg/kg and available K2O of; 6.4 mg/kg. Plant growth with poor growth criteria has a total N content of 0.20%, P2O5 of 115.1 mg/kg and K20 of 7.1 mg/kg. kg. while plant tissue has an N-Total content of 2.41%, P-Total of 0.26 percent and K-total of 2.47 percent for plants with very good growth criteria and N-total, P-total and K-total respectively - respectively .2.79, 0.32 and 3.95 mg/kg for plant tissue with poor growth criteria.

Abstract

Dilakukan perhitungan laju pertumbuhan relatif tanaman dan laju asmilasi tanaman selada yang ditanam dimedia hidroponik dengan ABmix yang disubstitusi pupuk organic cair (POC) asal limbah bulu ayam, untuk mengetahui dosis pemberian hara yang berimbang. Metode penelitian dilakukan dengan menggunakan Rancangan Acak Lengkap (RAL) tunggal yang terdiri dari 5 (empat) taraf perlakuan yaitu: K0 = nutrisi AB mix (kontrol) 5 ml/L , K1 =Abmix 4 ml/l + 1 ml/l POC bulu ayam, K2 = Abmix 2,5 ml/l + 2,5 ml/l POC bulu ayam, K3 = Abmix 2 ml/l + 3 ml/l POC bulu ayam, K4 = Abmix 1 ml/l + 4 ml/l POC bulu ayam. Hasil penelitian menunjukkan perlakuan POC bulu ayam mampu menyamai pertumbuhan Selada dengan sumber nutrisi dari hara sintetis ABmix. Hasil anova menunjukkan jenis perlakuan POC bulu ayam dan AB mix tidak berpengaruh nyata terhadap peubah tinggi tanaman, luas daun, jumlah daun, berat kering, laju asimilasi bersih, laju tumbuh relatif, laju tumbuh tinggi tanaman relatif, laju tumbuh luas daun relatif, dan laju tumbuh jumlah daun relatif. POC bulu ayam mampu mengimbangi pertumbuhan yang diberi hara AB mix pada pertumbuhan selada system hidroponik.
