These substances can be produced by plant metabolites and are also the results of metabolites produced by endophytic fungi. Endophytic fungus is an organism that is associated with healthy host tissues without causing disease symptoms. Endophytic fungi from betel leaf are used as biocontrol agents against Fusarium oxysporum causes wilt disease that attacks Chili (Capsicum annuum L.), which is one of the main agricultural commodities in Indonesia. Fusarium wilt disease is a disease that significantly reduces crop yields based on crop yields. This research was conducted in a chili farm in Cangkringan, Sleman, Yogyakarta. This study aimed to test the antagonism of endophytic fungi with the dual culture technique. Three types of green betel leaf endophytic fungi were used for dual culture test against Fusarium oxysporum. The observation result show...

The media used for culturing bacteria is a zobel synthesis medium with a mixture of seawater. The results of the isolation and extraction of color pigments obtained a red color with a characteristic wavelength of 535 nm and has a variety of chemical content results. Pigment immersion trials using 3 types of fabric, namely cotton, primisima and dobby fabric. The results of immersion with ethanolic solvent obtained optimum results for 12 hours and with the addition of mordant (Fe.H2O4S.7H2O), the color of the fabric is strong enough to withstand washing with detergent and sunlight. From the results of the study, data showed that the dyed primisima fabric gave a reduction or inhibition of the growth of E. coli bacteria by 9% while the inhibition of S. aureus bacteria was 116%. The pigment has the potential to be used ...

Chrysanthemum has a high economic value and potential to be developed. The diversity of morphological and anatomical characters is not currently widely practiced. This study aims to determine the morphological and anatomical characteristics of C. morifolium Ramat. var. puspitanusantara, and var. tirtaayuni and C. indicum L. var. mustikakaniya. Sampling by purposive random. The study was conducted in May - June 2017 in Kenteng Village, Bandungan District, Semarang District. The results showed that the results showed that C. morifolium Ramat var. puspitanusantara and var. tirtaayuni and C. indicum L. var. mustikakaniya have variations of morphology, especially on leaves and flowers, variations in leaf organ form, and base. Variations of flowering organs include the number of flowers per stem, the number of ribbon flowers, and the freshness of the flower. Anatomical characters based on tissue arrangement of ...

The liquid waste of processing cassava chips contains organic compounds that are easily decomposed and cause unpleasant odors. If the liquid waste is discharged directly into the environment, it will cause pollution and damage the environment. One of the steps that can be used to overcome this problem is phytoremediation. The purpose of this study was to determine the best treatment in the processing of cassava chips industrial wastewater so that the liquid waste is safe to dispose of into the environment. In this study, using two types of aquatic plants, namely water hyacinth (Eichhornia crassipes) and kiambang (Pistia stratiotes) and using alum to remediate liquid waste. This research was conducted experimentally using a jar with a diameter of 15 cm and a height of 25 cm with 3 repetitions of each treatment. The data obtained were analyzed descriptively to de...

Penelitian ini termasuk jenis penelitian Quasi Experimental (eksperimen semu). Desain penelitian yang digunakan adalah Pretest and postest control group design. Populasi penelitian adalah semua siswa kelas X SMA Negeri 2 Banguntapan. Sampel penelitian terdiri dari dua kelas yang diambil secara random (acak), yaitu kelas X3 sebagai kelas eksperimen dan kelas X4 sebagai kelas kontrol. Data penelitian berupa angket minat belajar siswa di analisis dengan Test Mann-Whitney U, hasil belajar kognitif siswa berupa Pretest dan postest di analisis menggunakan Independent Samples t Test, dan angket tanggapan siswa di analisis dengan analisis deskriptif. Hasil penelitian menunjukkan bahwa, pembelajaran proyek berbasis JAS lebih efektif daripada model ceramah ditinjau dari minat siswa, berdasarkan hasil Test Mann-Whitney U dengan signifikansi sebesar 0,024 (pada tingkat signifikansi 0,05), pembelajaran proyek berbasis JAS lebih efektif daripada model ceramah ditinjau dari hasil belajar siswa, berdasarkan Independent Samples t Test dengan signifikansi 0,048 (pada tingkat signifikansi 0,05), penerapan pembelajaran proyek berbasis JAS pada sub materi bryophyta dan pteridophyta mendapat tanggapan positif terbukti dari hasil analisis deskriptif dengan persentase rata-rata semua aspek memperoleh tanggapan 81,51% dengan kategori baik. Kata Kunci: model proyek, jelajah alam sekitar, minat siswa, hasil belajar

Mrs. Muryati, a resident of Kedungbulus Village, Gembong Subdistrict, Pati, was one of the residents who was moved to campaign for the use of Moringa leaves. The purpose of this study was to determine public perceptions about the potential of Moringa plants in the village of Kedungbulus Gembong Pati. This research uses survey methods which include: literature study, field observations, interviews using questionnaires, semistructure interview techniques and using random sampling techniques and purposive sampling. Random sampling sampling from the community taken randomly, while purposive sampling sampling from community leaders such as informants of production houses, village heads, shamans etc. The results obtained from the relationship between community and Moringa plants are explained from interviews with the public perception of Moringa plants.
