Abstract

The demand of oyster mushroom has increased. Hence the production should be improved as well. The purpose of research is to know the growth response and production of several varieties of oyster mushroom on the powder media of palm stem waste and sawdust. Research conducted in Sumatra mushroom oyster cultivation. The design used in this study is a Complete Random Design (CRD) factorial that is of 2 factors. The first factor is the composition of the planting media of palm oil and sawdust was conducted with 2 repeats. The Parameter of observation on the study is the percentage of baglogs covered by mycelium (%), the growth of mycelium on the substrate (cm), the age of the body of the fruit (DAI), Number of fruit body (fruit), diameter of the hood (cm2) The stem length of the fruit body (cm) and the wet Harvest weight (g). The results showed that the best treatment for the growth of mycelium and the age of fruit body in total saw dust amd and varieties jamur tiram 58.38 days formation of the first fruit body.

Abstract

To improve the quality of pepper products through organic cultivation using organic growth regulators. This Research aims to investigate concentration and long immersion effect of golden snail meat (Pomacea canaliculata L.) on the growth of pepper cuttings (Piper nigrum L.). the method was experimental with a randomized block design (RAK) Factorial design with two factors namely various golden snail meat concentrations and long immersion ranging from several hours. The parameters observed in this study was Growth Percentage (%), Bud Height (cm), Number of Leaves (Strands), Root Length (cm), and Root Volume (ml). The results showed that the treatment of snail meat zpt concentration did not significantly affect the shoot height parameters but significantly affected the percentage of growth, number of leaves, root length and root volume where the effective zpt concentration was 50%. The long immersion treatment significantly affected the percentage of growth and shoot height where the best treatment at w1 was 3 hours’ immersion. The treatment combination of ZPT golden snail meat (Pomacea canaliculata L.) and long immersion did not significantly affect all observations parameters.

Abstract

The Waste Utilization Of Jengkol Peel As Raw Material Compost And Biochar In Increasing Growth And Production Of Onion (Allium Ascalonicum L.). Guided by Dr.Ir. Sumihar Hutapea, MS and Ir.H.Abdul Rahman, MS. This research aimed to determine effect of giving compost jengkol peel on the growth and production of onion, effect of giving biochar jengkol peel on the growth and production of onion, and effect of the combination between compost and biochar waste of jengkol peel on the growth and production of onion (Allium ascalonicum L.). This research was conducted in the House Kasa Growth Centre Kopertis Region I North Sumateta-Nanggroe Aceh Darussalam from April until September 2016. The research was conducted by planting in polybags with soil weight 5 kg/polybag. This research was conducted by using Randomized Block Design (RBD) factorial with 2 factors treatment. The first factor is compost of jengkol peel that consists of 4 levels dose are : K0 = (control), K1 = (10 ton/ha or 25 g/polybag), K2 = (20 ton/ha or 50 g/polybag), K3 = (30 ton/ha or 75 g polybag). The second factor is biochar of jengkol peel that consists of 4 levels dose are : B0 = (control), B1 = (5 ton / ha or 12.5 g / polybag), B2 = (10 ton / ha or 25 g / polybag), B3 = (15 ton / ha or 37.5 g / polybag). The results of research showed that treatment of jengkol peel compost was very significant effect on plant height at of 2 and 3 MST observation, significant effect on the observation aged 4 and 5 MST, and it is not affected real to the age of 6 MST observation. To the observations on the number of leaves on the age of 2, 3 and 4 MST is very significant effect, significant effect on the age of 5 MST observation and not affected real on the age of 6 MST observation. On the number of cloves and tuber diameter is not affected real. Fresh weight of tuber and dry weight of tuber is significant effect. Treatment of jengkol peel biochar is not affected real on all parameters of observation. Interaction treatment of compost and biochar of jengkol peel is significant effect on leaf length 2 and 3 MST, number of leaf age 2 MST and it is not affected real on other parameters.
