Abstract

Learning outcomes Based on the observations of the current researchers Practice Experience (PPL) and interviews with subject teachers Building Construction SMK 1 Palangkaraya, obtained information that the majority of students are less eager to absorb the lessons Building on the material type and classification steel. This is due to the tendency of teachers presenting the material directly, so that learners are not actively involved in learning. This can be seen from the value of student learning outcomes in subjects Building Materials class X Architecture Engineering SMK 1 Palangkaraya Academic Year 2014/2015 on the material type and classification of steel which is still relatively low. From some of these problems, so in this study used a model of learning discovery learning in hopes of making learning material types and classification of steel more meaningful and fun. So as to make students actively involved during the learning process and the classification of the type of steel in the classroom so that student learning outcomes increases. This study used a quasi-experimental research designs Nonequivalent type Control Group Design. The population in this study were all students of class X engineering drawings SMK- 1 Palangkaraya totaling 28 students. Sampling was carried out using saturated sampling technique in which all members of the population being sampled. Design approach used is a quantitative approach. This study was conducted in December to February 2015. The data is taken from the data of student learning outcomes obtained through the covers pretest and posttest. Based on the results of research conducted in class X drawing technique building with 28 students, there is a difference between the experimental class and the control class. It can be seen from the average value of students being taught by learning discovery learning model is better than being taught by conventional learning, where the average value of the experimental class at 90.19, while the average value of 74 control class.

Abstract

The pineapple waste increased by the rise of production in pineapple, one of increasing pineapple waste is pineapple pulp (bromelain litter). The bromelain litter will be disadvantage for the environment, this matter could be solved by converting bromelain litter into compost. The composting process in this study used ligninolytic fungus (Trichoderma sp.). Composting technology which currently has rapidly developed is Aerated Compost Tea (ACT) or a derivate product of compost. The use of this study was to ensure the best incubation period of ACT bromelain litter which induced by Trichoderma sp. fungus on the growth of tomato (L. esculentum Mill.). The study was conducted using a completely randomized design (CRD) with 7 treatments and 3 replications, namely: P0= control (without ACT), P1= ACT bromelain 24 hours, P2= ACT bromelain 48 hours, P3= ACT bromelain 72 hours, P4= ACT bromelain and leaf litter 24 hours, P5= ACT bromelain and leaf litter 48 hours, and P6= ACT bromelain and leaf litter 72 hours. The variables observed were number of leaves and plant chlorophyll content. The data obtained were analyzed with ANOVA at the level of 5 % and tested for the Least Significant Difference (LSD) at the level of 5 %. The results of this study showed that ACT was induced by Trichoderma sp. fungus which effective for the vegetative growth of tomato (L. esculentum Mill.) is ACT bromelain litter with incubation period up to 72 hours (P3).

Abstract

Cassava (Manihot esculenta Crantz) is a plant that is widely cultivated in Indonesia, this is because cassava is one of the staple food sources and sources of income throughout the tropics, but in the planting process, farmers are often constrained by attacks by pathogenic fungi that cause fusarium wilt disease and cause the quality of cassava plants to decline. One way to control this disease is by selecting cassava plants in the planting medium in vivo through salicylic acid infiltration to increase resistance to pathogens and improve the quality of cassava plants. The purpose of this study was to determine the effect of salicylic acid on the number of leaves, leaf stomatal index, and phenol content of cassava plants resistant to Fusarium oxysporum compared to controls. This study used a one-factor Completely Randomized Design (CRD) with 5 levels of salicylic acid concentration, namely 0 ppm, 80 ppm, 100 ppm, 120 ppm and 140 ppm. Data analysis using Analysis of Variance (ANOVA) and further testing with Tukey test at the 5% level. The results showed that the concentration of salicylic acid that was tolerant for cassava plant selection with optimum growth was 100 ppm which was indicated by an increase in the number of leaves and leaf stomata index while the most optimum concentration of salicylic acid for increasing phenol levels was 140 ppm Keywords: salicylic acid, cassava, Fusarium oxysporum, induced resistance

Abstract

Large red chili (capsicum annuum L.)  is a herbaceous plant that has a spicy taste and is one of the types of chili that is most widely used by the Indonesian people, especially on a household scale by 61%. Therefore, increasing the production of large red chili needs to be done, one of which is through the administration of gibberellin and Local Microorganisms (MOL) from Batu banana corms. This study aims to determine the effect of administering gibberellin (GA3) and MOL from Batu banana corms on the growth of large red chili plants, determine the most effective concentration, and observe the interaction between the two. The study was conducted from February to March 2024 at the Botany Laboratory, FMIPA, University of Lampung, using a factorial Completely Randomized Design (CRD). The first factor was gibberellin with two concentration levels (0% and 10%), and the second factor was MOL from Batu banana corms with three concentration levels (0%, 10%, and 20%) with five replications, resulting in 30 experimental units. The parameters observed included plant height, root length, fresh weight, dry weight, relative water content, chlorophyll content, and leaf visualization. Data were analyzed using ANOVA followed by a 5% Tukey test. The results showed that the combination of 10% GA3 and 20% MOL affected fresh weight, dry weight, and chlorophyll a, b, and total, while the control affected plant height, root length, and relative water content.

Abstract

Red chili (Capsicum annuum L.) is an important horticultural crop that is widely used as a cooking spice. However, this fruit has a short shelf life and is susceptible to Colletotrichum sp. infection which causes anthracnose disease. One effort to extend the shelf life and suppress fungal infection is the use of natural coatings. Sweet orange peel(Citrus aurantium L.) which contains pectin has the potential to be used as a base material for natural coatings to increase the resistance of red chili. This study aims to determine the effect and determine the effective concentration of natural coatings from sweet orange peel on the quality of red chili and its resistance to Colletotrichum sp. The study used a Completely Randomized Design (CRD) with six treatment concentrations: 0%, 1%, 2%, 3%, 4%, and 5%, each repeated four times. The parameters observed included texture, weight loss, incubation period, disease incidence, disease severity, and number of conidia. The results showed that a concentration of 5% gave the best results in maintaining fruit texture and weight, extending the incubation period, and inhibiting disease development and reducing the number of Colletotrichum sp. conidia.
