Abstract

The use of entisol soils can be maximized by adding organic matter. One ingredient that is able to maintain water availability and water resistance is biochar which is added to Tithonia as biochar plus. This study aims to determine the benefits of biochar plus on coastal entisol soils and mustard greens (Brassica juncea L.). The study used a Completely Randomized Design (CRD) with 6 treatments and 3 replications, namely 0% coconut shell biochar + 0% Tithonia compost (O); 100% coconut shell biochar + 0% Tithonia compost (A); 75% coconut shell biochar + 25% Tithonia Compost (B); 50% Coconut Shell Biochar + 50% Tithonia Compost (C), 25% Biochar Coconut Shell + 75% Tithonia Compost (D), 0% Biochar Coconut Shell + 100% Tithonia Compost (E). Data from observations were analyzed with variance (F test), if F count was greater than F table at 5% significance level followed by Duncan's Multiple Range Test (DMRT) at 5% significance level. The parameters observed include soil analysis which includes, pH, N-total, P-available and K-dd as well as plant observations including plant height, number of leaves and root length. The results showed that Biochar plus affected the Entisol soil and the growth of mustard plants, namely the most influential formulation was 75% coconut shell biochar + 25% Tithonia compost which was seen in the height parameters of mustard greens.

Abstract

Pemanfaatan lahan kering pada kawasan pesisir untuk budidaya tanaman padi gogo mempunyai potensi besar untuk pemantapan swasembada pangan maupun untuk pembangunan pertanian kedepan. Keterbatasan kesuburan yang dimiliki lahan di kawasan pesisir dapat diatasi dengan menggunakan teknologi yang tepat seperti penggunaan varietas yang unggul dan pupuk hayati serta biokompos. Penelitian ini bertujuan untuk mengetahui karakteristik biologi dan kimia tanah serta pertumbuhan padi gogo di kawasan pesisir. Rancangan percobaan yang digunakan adalah rancangan petak terbagi dengan petak utama adalah 3 varietas padi gogo yang didapatkan dari BPTP Bengkulu yaitu varietas Inpago 10, Serantan, dan Lokal Bengkulu, dengan anak petak yaitu inokulan ganda mikroba pelarut P (pf) + mikroba pelarut K + mikroba pemfiksasi N, inokulan ganda mikroba pelarut P (fma) + mikroba pelarut K + mikroba pemfiksasi N, biokompos dengan dosis 10 ton ha-1, dan pupuk anorganik rekomendasi BPTP yaitu 200 kg Urea/ha, 100 kg SP36/ha, 100 kg KCl/ha, diulang 4 kali. Hasil penelitian menunjukkan bahwa aplikasi pupuk hayati maupun biokompos yang ditanami padi gogo varietas Inpago 10 di area pesisir mampu meningkatkan karakter biologi dan kimia tanah. Padi gogo varietas Serantan dengan aplikasi inokulan ganda mikroba pelarut P + mikroba pelarut K + mikroba pemfiksasi N di area pesisir mampu menghasilkan jumlah anakan tinggi dengan tinggi tanaman rendahKata kunci: adaptabilitas, lahan pesisir, padi gogo, pertumbuhan, pupuk hayati.

Abstract

This study aims to determine the appropriate thickness of cassava skin and durian skin in reducing the levels of Fe and Mn contained in dug well water. The study was designed using a single factor complete randomized design, namely the thickness of the waste cassava skin and durian skin which included 0 cm (control), 15 cm, 30 cm, and 60 cm. Each treatment was repeated 3 times to obtain 12 experimental units. Water samples were taken by a dug well from one of the residents' houses in RT 08, Padang Serai Village, Bengkulu City. Furthermore, the water samples were taken to the Bengkulu Ministry of Health Poltekkes Environmental Health Workshop. Observational data will be analyzed statistically using ANOVA level of 5%. Then if the data is significantly different, it will be tested further with the Least Significant Difference (LSD) Test. The results showed that the application of cassava peels and durian peels reduced Fe and Mn levels compared to controls. Application of cassava skin waste and durian skin with a thickness of 30 cm in water treatment of dug wells because they are able to reduce Fe and Mn levels below the threshold and is more economical.
