Abstract

The potency of calabur tree (Muntingia calabura) leaf extract to control anthracnose of papaya fruit. The papaya anthracnose caused by Colletotrichum gloeosporioides is one of the factors causing a decrease in papaya production. The research aimed to determine the abilty of calabur tree leaf extract in inhibiting growth, sporulation, and viability of C. gloeosporioides as well as incubation period and disease severity on the fruit of papaya. The experiment was arranged in a nested design, the concentrations (0, 10, 20, 30, 40, 50, and 60%) were nested within the calabur tree leaf extract methods (boiling and fractionation). The results showed that boiled calabur leaves extract was more effective than fractionated calabur leaves extract to inhibit growth of C. gloeosporioides. Boiled calabur leaves extract and fractionated leaves extract at various concentration showed capability to inhibit the growth, sporulation and viability of C. gloeosporioides. Boiled calabur leaves extract at different concentration levels were able to suppress disease development of papaya anthracnose disease on papaya fruit. The higher concentration of calabur leaves extract, are more effective to inhibit C. gloeosporioides.

Abstract

Inhibitory effect of pace extraction on growth of pathogen and development of bacterial wilt of banana disease. Bacterial wilt of banana (Ralstonia solanacearum) is one of banana diseases that potentially destructs banana plants in some areas.  A study on the effect of extract of pace plant against bacterial wilt of banana were carried out in laboratory and experimental farm of Plant Protection Department, College of Agriculture, University of Lampung from May until October 2003. The study consisted of in vitro and intact plant experiments. The treatments for both in vitro and intact plants were (1) steril water (control), (2) extract of pace fruit, (3) extract of pace fruit leaves, (4) extract of pace roots and (5) bactericide (agrymycin sulfate). In vitro study was conducted by using completely randomized design, while intact plant study was conducted by using completely randomized block design. The results showed that extract of fruit, leaf and root of pace suppressed the growth of R. solanacearum in vitro. Fruit extract had the highest ability in suppressing the growth of bacterial wilt. However, the application of all kind of extiact did not suppress the incident of bacterial wilt of banana plant.

Abstract

Influence of Aglaia odorata L. leaf extract on in vitro growth of chilli antrachnose fungi (Colletotrichum capsici). Pacar cina (Aglaia odorata L.) is known as one of the potential herbs as fungicides. The objective of this study was to determine The effectiveness of various leaf extract fractions of pacar cina as a fungicide to suppress the in vitro growth of C. capsici, The causal agent of anthracnose disease on chili. This study consisted of two sub-experiments. The first experiment consisted of 12 treatments: leaf extract fractions with distilled water solvent, leaf extract fractions with ethanol solvent with a concentration of 10, 20, 30, 40, 50, 60, 70, 80 and 90%, propineb 0.2 % (synthetic fungicides) and control (without fungicide). The Second experiment consisted of 12 treatments: leaf extract fractions with distilled water solvent, leaf extract fractions with the solven of n-hexane at a concentration of 10, 20, 30, 40, 50, 60, 70, 80 and 90%, propineb 2% (synthetic fungicides), and control (without fungicides). The treatmentswerearranged by completely randomized design (CRD) with three replications. Variables measured in this experiment were colony diameter and density of spores of C. capsici. Data were analyzed by analysis of variance (ANOVA) and differences between the mean values was tested by Duncan Multiple Range Test (DMRT) with the level of 5% significant different. Additionally, leaf extract that effectively inhibited the growth of C. capsici was the fraction of the leak extract with 80% ethanol solvent and 10%, 60%, and 90% n-hexanesolvent. The result showed that the leaf extract fraction of pacar cina was potentially used as fungicide to inhibit the growth of C. capsici.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh strategi Segmentasi, Targeting dan Positioning Terhadap Keputusan Menjadi Nasabah pada PT. Bank Syariah Mandiri KCP Kuala Tungkal. Fokus penelitian adalah Segmentasi, Targeting dan Posioting pada Nasabah pembiayaan. Pendekatan yang digunakan pada penelitian ini adalah pendekatan kuantitatif. Riset ini menggunakan metode campuran (mixed Methods) yaitu campuran metodologi penelitian kuantitatif dan metodologi penelitian kualitatif. sumber data yang digunakan sumber data Primer dan sumber data sekunder. Subjek penelitian ini adalah Nasabah Bank Syariah Mandiri dalam periode waktu tahun 2016 sampai tahun 2019. Data akan diolah dengan menggunakan metode analisis regresi linier berganda menggunakan aplikasi spss versi 2.6. Hasil penelitian ini menunjukkan secara parsial variabel strategi segmentasi (X1) -0.465 < 1,968 yang artinya tidak terdapat pengaruh, variabel targeting (X2) 0,097 < 1.968 yang artinya tidak terdapat pengaruh, dan variabel potitioning (X3) 1.670 < 1.968 yang artinya terdapat pengaruh tidak signifikan pada alpa 10%. Maka hasil hipotesis yang diperoleh dari penelitian ini adalah terdapat pengaruh yang signifikan antara variabel strategi marketing (Segmentasi, targeting dan potitioning). Sedangkan secara simultan F hitung sebesar 0,931 d F tabel 2,64 yang artinya F hitung < F tabel sehingga H0 diterima yaitu secara simultan tidak terdapat berpengaruh terhadap variabel dependen. Secara parsial pengaruh variable segmentasi 0.003, variable targeting 0.001 dan variable potitioning 0.998 terhadap keputusan menjadi nasabah, jika dilihat dari nilai R adalah 0.100 yaitu berpengaruh sebesar 10%, sedangkan sisanya dipengaruhi oleh variabel lain yang tidak diteliti dalam penelitian ini.
