Abstract

The purpose of this research is to get plant medium, dosage of NPK fertilizer and its interaction suitable for growth of cuttings of rose plants. This research has been conducted in Experimental Garden of Faculty of Agriculture, University of Riau. This research took place from October 2016 until January 2017. This research was conducted experimentally using Completely Randomized Design (RAL), Factorial and 3 replications. Factorial consists 2 factors. The first factor of planting medium (M) consists of 3 levels: M1 = Incepticol soil, M2 = sawdust, M3 = rice husk. The second factor of NPK (P) consists of 4 levels: P0 = without NPK, P1 = NPK 1 g/plant, P2 = NPK 2 g/plant, P3 = NPK 3 g/plant. Each unit consists of 2 plants of roses. Parameters those observed shoot lengths, number of shoots per plant, number of leaves per plant, age of first flower appeared, the number of flowers per plant and root length. The results obtained were analyzed using anova and HSD  of 5%. The results showed rice husk medium, the dose of NPK 1 g / plant fertilizer and better interaction in improving plant growth. Keywords:Setek roses, Medium plants, NPK Fertilizer.

Abstract

One of the disease that can significatly decrease the red chili productivity is virus complex. The disease can be controlled by the utilization of microorganism such as Trichoderma koningii Rifai formulated in a biofungicide. The dose of biofungicide given to the plants can determine the effect of virus complex disease. The research aims to obtain the best dose of biofungicide of     T. koningii to increase the resistance of red chili to virus komplex and to study its effect on the growth and yield of the red chili. This research has been conducted at Plant Pathology Laboratory and Agribusiness Incubator Green House, Agriculture Faculty of Riau University from October 2015 to February 2016. The research was carried out experimentally using a completely randomized design consisted of 5 doses (0, 25, 50, 75 dan 100 g/polybag) and 3 replication. Data obtained were statistically analyzed using analysis of variance and continued with Duncan’s New Multiple Range Test (DNMRT) at 5% level. The result showed that the virus complex infection in red chili which were applied with some doses of biofungicide of T. koningii had different effect on the first time of symptom appeared, disease intensity, plant growth and yield. Biofungicide of T. koningii at 100 g/polybag can increase the resistance of red chili and the growth and production. Keywords: Biofungicide, Trichoderma koningii, virus complex, red chili

Abstract

Sweet corn is one of the plants that have a big role in providing the nutritional needs of the community. One effort that can be done to increase the growth and production of sweet corn is fertilization. The purpose of this research is to know the effect of Sludge palm oil mill combination with N, P and K fertilizer on the growth and production of sweet corn and get best treatment from Sludge combination of oil palm factory with N, P and K fertilizer to increase plant growth and production sweet corn. This experiment was conducted experimentally using Randomized Block Design (RAK) consisting of 12 treatments and 3 replications to obtain 36 experimental units. The treatment is a combination of solid waste (Sludge) of oil palm factory with N, P and K (Urea, TSP and KCl) fertilizers. Observation parameters consisted of plant height, stem diameter, female flowering time, harvest age, weight of cobweb and no weight, length of cob, diameter of ear, and production / m2. The result of this research showed that the combination of sludge treatment with N, P and K fertilizer had significant effect on all observation parameters. The best combination of sludge was found in a combination of 15 tons / ha sludge and N, P and K fertilizer (150 kg Urea, 100 kg TSP and 75 kg KCl) / ha. Keywords: Sweet corn, Sludge, N, P and K fertilizer

Abstract

The purpose of this research was to evaluate know the position of the best banana chips products and attributes of various kinds of banana chips. This objective of this study was  to determine the level of consumer preference to a product that was banana chips. At this time which was still the lack of efforts of producers in developing their products.  This research were carried out experiments using seven producs (brand of banana chip), which consists of KP1: Wahana, KP2: Alfamart, KP3: Mekar Jaya, KP4: Sumber Hidup,  KP5: Winda, KP6: Elsa Snack, and KP7: Yadi Bersaudara.  Data were analyzed statistically by using a Preference Test Mapping with assistance XL STAT software version 2014. Test hedonic and descriptive test analyzed were using Principal Component Analysis(PCA). Agglomerative hierarchical clustering (AHC) was used to see all grades of banana chips. Based on the descriptive analysis using PCA and hedonic analysis using the AHC showed that banana chips KP7 and analysis of the main components of the descriptive (PCA) test were then analyzed by using the preference mapping technique, with the sensory attributes used in banana chips products are banana flavor, saltiness, sweet taste, burnt, savory, crunchy, yellow, brownish yellow, banana scent, vacancy rate, texture crispness. The most preferred product in the study were Winda banana chips, Elsa Snack, and Yadi Bersaudara most favored by panelists. Keywords:Banana chips, consumer preferences, PCA, AHC.

Abstract

This study aims to determine the abundance (type and amount) soil mesofauna and rubber tree growth (Havea brasiliensis Muell. Arg) in peat soil with different conditions of Mucuna bracteata. This research has been conducted in peat soil at social plantation area of PT. RAPP Teluk Meranti from January to March 2016. Analysis soil mesofauna and analysis soil carried out in the laboratory of soil science, Faculty of Agriculture, University of Riau. This research used purposive random sampling namely in rubber contained Mucuna bracteata life, Mucuna bracteata dead and without Mucuna bracteata. Determining the plant sample was randomly with diagonal method in order to get 5 rubber trees that are Mucuna bracteata life, 5 Mucuna bracteata dead and 5 without Mucuna bracteata. Data obtained from the calculation and interpretation of the data be stated in tables and analyzed statistically descriptive. The research show that in stands of rubber trees in the peat soil contained Mucuna bracteata life shows number of individual, family and population density (Kp) soil mesofauna is highest compared with Mucuna bracteata dead and without Mucuna bracteata. Abundance of soil mesofauna highest in rubber tree stands on peat soil which are Mucuna bracteata life dominated by the family Macrohelidae, Mucuna bracteata dead dominated by the family Macrohelidae and without Mucuna bracteata dominated by the family Hirudisomatidae. The rubber tree that is Mucuna bracteata life having the average circle stems is larger compared with Mucuna bracteta dead and without Mucuna bracteata.

Abstract

The study was purposed to get the best combination of rosella flower petals (Hibiscus sabdariffa L.) and seaweed (Euchema cottoni).  The research used a Complete Randomized Design (CRD) with 5 treatments and 3 replications. The treatments were rosella flower petals 90% : seaweed 10%, rosella flower petals 80% : seaweed 20%, rosella flower petals 70% : seaweed 30%, rosella flower petals 60% : seaweed 40%, and rosella flower petals 50% : seaweed 50%.  The data obtained were analyzed statistically using Anova and DNMRT at 5%.  The research showed that rosella flower petals and seaweed significant on water content, ash content, degree of acidity (pH), reducing sugar, and sensory evaluation for descriptif and hedonic test. The best treatment of jelly bean from this research was rosella flower petals 60% and seaweed 40% which have water content 16,59%, ash content 0,24%, degree of acidity (pH) 5,81, reducing sugar 23,14%, reddish orange color, a little bit rosella flavour, sweet little sour taste, the texture was little springy and overall assesment of jelly beans was  rather preferred by the panelist’s. Keywords: Jelly beans, rosella flower petals and seaweed.
