Abstract

Sweet corn is one of the agricultural commodities that is widely consumed because it contains various nutrients that are needed by the human body. Sweet corn production is strongly influenced by several things, including the adequacy of nutrients in the soil. To meet the needs of plant nutrients can be done through fertilization activities. The effectiveness of fertilization is strongly influenced by the dose, type, method and time of application. This study aims to determine the growth and yield of sweet corn plants due to the application of Urea, SP36, and KCl  fertilizers with different doses. The results showed that the treatment using Urea, SP36, and KCl fertilizers with different doses had a significant effect on the variables of plant height, weight of cobs with beans, and weight of cobs without beans. However, there was no significant difference in the number of leaves, ear diameter, dissolved solids, and yield per hectare

Abstract

Natural latex is an agricultural product that has a lot of benefits human needs. The efforts to increase latex production have to be continually done in order to meet the requirement. Paying attention to the time of latex taking and giving latex stimulant treatment are the important efforts. Both the efforts have to be taken care very well to prevent the damage on the coutchouc. The objective of the study is to know the effect of applying ethepon and the time of latex taking to word latex production on the coutchouc and the interaction between both of the factors. The research took place in Dharma Agung Village sub-distric of Seputih Mataram, Central Lampung regency on May—July, 2013. The ingredients used in the research are: coutchouc clone PB 260, ethepon with Cepha 100 PA brand (1,5% and 2,5% of concentration), acetic acid and aquades.  The research is in factorial pattern which is arranged in complete randomized block design by three repetitions. The first factor is the application of ethepon (A) divided into three treatments: non ethepon application (a1), ethepon application with 1,5% concentration (a2), and ethepon application with 2,5% concentration (a3). The second factor is the time of latex taking (T) at 05.00 a.m. (t1), at 07.00 a.m. (t2), and at 09.00 a.m. (t3). Based on the finding of the research, it can be concluded that the use of ethepon with 2,5% concentration and the earliest time latex taking (at 05.00 a.m.) produce the highest amount of latex than others treatments.Keywords: Latex, Ethepon, Latex Taking Time

Abstract

Kimchi is a food that has a distinctive taste, which is sour due to the fermentation process.  Kimchi made from vegetables and various spices in the form of spices.  This research is about salt concentration and fermentation time on vitamin C content and organoleptic quality of kimchi pakcoy.  The research method used is the method of description (single factor; two replications) by presenting the results of observations in the form of a histogram, then discussed descriptively.  The treatment factor is a combination of salt concentration and fermentation time. Salt concentration (K) which consists of 3 levels, namely: K1 (2%), K2 (4%) and K3 (6%) and the duration of fermentation (L) which consists of 3 levels, namely: L1 (2 days), L2 (4 days) and L3 (6 days).  The parameters analyzed were vitamin C content and organoleptic quality related to taste, aroma, color and texture.  Salt concentration and fermentation time greatly affect the content of vitamin C and organoleptic quality.  The highest vitamin C content was found in the K3L3 sample, namely 6% salt concentration and 6 days of fermentation time with a vitamin C content of 0.7320 mg / gr.  Organoleptic quality using the hedonic test, related to taste, aroma, color and texture, yielded successive values, namely 5.2 (K3L2); 5,6 (K2L3); 5.9 (K1L1); 6.1 (K1L1)

Abstract

The effectiveness of Arbuscular Mycorrhiza Fungi (AMF) colonization depends on the type of AMF, plant species and phosphorus fertilization.  The aims of this study were to determine: the best type of AMF and the appropriate dosage of P fertilizer for the growth of oil palm seedlings, and whether the oil palm seedling responses to the application of AMF type is determined by the dosage of phosphorus applied. The experiment was arranged in a Randomized Complete Block Design (RCBD) with two factors and 5 replications. The first factor was the types of AMF (m), consisting of without mycorrhiza inoculation (m0), Gigaspora sp. MV16 isolate (m1), Glomus sp. MV7 isolate (m2), Gigaspora sp. MV16 isolate + Glomus sp. MV7 (m3) isolate.  The second factor was phosphorus fertilization (SP-36), consisting of 3 levels: 1/3 recommended dosage (p1), 2/3 recommended dosage (p2), full recommended dosage (p3). The results showed that the application of all AMF types resulted in the same effects on the growth of oil palm seedlings, however the seedling growth in the inoculated plants were better than in uninoculated plants (control). The application of the recommended dosage of P fertilizer produced the highest seedling growth. The response of seedlings to the application of AMF type was not determined by doses of phosphorus fertilizer applied.

Abstract

Yards are generally planted with various types of plants, ranging from high crown plants to low crownplants. However, choosing the wrong types of plants actually makes land use not optimal because notall plants planted can produce. Banana is a commodity that is widely grown around the house and inmixed gardens. The existence of vacant land in the yard of the KWT Rukun Tani member's house, AdiWarno Village, Batang Hari District, East Lampung Regency has the potential to be planted withbananas. Although some members have planted bananas in their yards, their growth and productivityis still low due to limited knowledge and skills in banana cultivation. The purpose of community serviceactivities is to transfer knowledge from tertiary institutions (service teams) to the community (KWTRukun Tani), through counseling activities and banana cultivation demonstration plots for the use ofyard land and increasing the income of KWT members. Based on the activities that have been carriedout, members of KWT Rukun Tani feel that the service activities carried out are very useful becausethey get new knowledge about good and correct banana cultivation. Currently the bananas planted indemonstration plots, in the yard and in the collective garden, are growing very well and some of theplants have started to bear fruit.
