Abstract

Providing manure can not only increase the availability of nutrients but also support the growth of microorganisms. Zeolite has a high CEC, which results in the media being able to bind water and nutrients added to the soil. This study aims to get the best type of manure on cocoa seedling growth, get the effect of zeolite smoothness on the growth of cocoa seedlings, and find out the interaction of the composition of manure and zeolite on the growth of cocoa seedlings. The research was conducted at Experimental Garden of Politeknik Negeri Lampung, from December 2017 to May 2018. The method used was the factorial pattern randomized block design (RBD) which consisted of two factors. The first factor consists of three levels, namely without manure, 200 g chicken manure, and 200 g goat manure. The second factor consisted of three levels, namely zeolite size (without zeolite, zeolite size 30 mesh, and zeolite size 16 mesh). Observation variables were plant height, leaves number, stem diameter, shoot dry weight, soil pH, and soil CEC. The results showed that manure did not show an effect on plant height, stem diameter, and leaves number, but had an effect on soil pH and soil CEC. The level of zeolite smoothness does not affect plant height, stem diameter, leaves number, and soil pH, but affects soil CEC the 16 mesh size of compared to 30 mesh size. There is no interaction on types of manure and size of zeolite fineness of plant height, stem diameter, leaves number, shoot dry weight, soil soil pH, and soil CEC.

Abstract

This study aims to obtain the best slurry dosage for the growth of cocoa seedlings. This reaserch was conducted in the experimental garden, chemical analyzed laboratory, and soil laboratory of Politeknik Negeri Lampung on November 2017 until March 2018. The method used was a Completely Randomized Design (CRD) with 6 doses of slurry (0 ml, 80 ml, 160 ml, 240 ml, 320 ml, and 400 ml). Observation variables in the form of premilinary observations abd observations during the study. Preliminary observations analyzed the levels of N, P, K, pH, and C-Organic on topsoil and slurry. Obsevation during the study were plant height, stem diameter, number of leaves, dry weight of shoot dry weight, root dry weight, and moisture content. The results showed that slurry doses did not affect on the cocoa seedling growth.
Respons Pertumbuhan dan Rendemen Minyak Klon Nilam (Pogostemon cablin Benth) terhadap Aplikasi Berbagai Dosis Urea (Growth Response And Yield Of Patchouli Clones (Pogostemon Cablin Benth) On Dose Urea Various Applications) Retno Ayu Diah Pangestu; M. Tahir; Fatahillah Fatahillah

Abstract

Patchouli (Pogostemon cablin Benth) is a plant known to produce essential oils, and is also an important foreign exchange earner for Indonesia. However, the use of superior clones and appropriate fertilizers tend to drastically increase product yield. This research aims to obtain species with the best response to urea fertilizers, and the right dosage for optimum performance. The study was conducted at the Politeknik Negeri Lampung’s teaching farm from December 2018 to May 2019, using a factorial randomized block design (RBD). This consisted of two treatment factors, including the 2 level clone consisting of The NPL 9 and Lhokseumawe, and 4 level urea dose control at, 250 kg.ha-1, 300 kg.ha-1, and 350 kg.ha-1. Furthermore, variables observed included plant’s height, bough, diameter, number of leaves, stalk angle, chlorophyll content, wet weight of plant, wind dry weight of plant, and yield.  The results shows NPL 9 clone has a superior appearance and the urea value of 350 kg.ha-1  was attributed as the optimal dose, yielding a 2,3%  increase compared to the control treatment.

Abstract

Limbah kulit singkong merupakan salah satu limbah yang memiliki potensi besar untuk dapat dimanfaatkan sebagai pupuk kompos. Kompos dapat digunakan sebagai pengganti pupuk buatan dengan biaya yang sangat murah. Kompos berfungsi dalam perbaikan struktur tanah, tekstur tanah, aerasi, dan peningkatan daya serap air tanah. Tujuan dari program ini adalah menjadikan kompos kulit singkong sebagai solusi pemanfaatan limbah sisa tanaman yang melimpah di desa mitra. Metode yang digunakan dalam penelitian ini adalah deskriptif kualitatif, yaitu keberhasilan pengomposan dinilai berdasarkan warna, aroma, dan tekstur yang dihasilkan. kegiatan mulai dari penyiapan bahan baku kulit singkong, pencacahan menggunakan enumerator, penyiapan dan pembibitan aktivator, tahapan pembuatan kompos mealui; susun, pengiriman EM4, pembalikan, pematangan, penyaringan, pemeliharaan dan kontrol dalam proses pengomposan, pengemasan dan penyimpanan. Hasil penelitian menunjukkan bahwa kompos singkong yang sudah matang mengalami penyusutan hampir 50%, teksturnya gembur saat dipegang, lembab, berwarna coklat kehitaman, dan tidak berbau (bau tanah).
