Abstract

AbstrakLalat buah telah diketahui secara luas sebagai hama utama pada komoditas buah di Indonesia sehingga menyebabkan kerugian ekonomi yang besar. Daun kersen (Muntingia calabura) telah diteliti mengandung beberapa senyawa yang berpotensi untuk mengendalikan serangan lalat buah. Penelitian ini bertujuan untuk mengetahui pengaruh ekstrak etanol daun kersen terhadap Bactrocera carambolae, salah satu jenis lalat buah yang menyerang berbagai buah-buahan sebagai inangnya. Ekstrak etanol daun kersen dengan konsentrasi yang berbeda yaitu 0%, 2,5%, 5% dan 7,5% disemprotkan ke permukaan buah jambu biji (Psidium guajava) dan diamati pengaruhnya terhadap lalat buah tersebut. Parameter dalam penelitian ini yaitu jumlah pupa dan jumlah lalat dewasa. Data dianalisis menggunakan uji analisis varians (uji F) α = 0,05 dilanjutkan dengan uji Beda Nyata Terkecil (BNT). Hasil penelitian menunjukkan semakin tinggi konsentrasi ekstrak yang diuji maka semakin kuat pengaruhnya pada penurunan jumlah pupa dan lalat dewasa. Berdasarkan hasil penelitian ini maka ekstrak etanol daun kersen diharapkan dapat menjadi alternatif untuk pestisida sintetis.Abstract Fruit flies are known as major fruit pest in Indonesia that cause economic losses. Muntingia calabura leaves has been observed to contain compounds that can potentially control the fruit fly. This research aimed to investigate the effect of ethanolic extract of M. calabura leaves againts Bactrocera carambolae, one of fruit flies which has wide range host. Ethanolic extract of M. calabura leaves with different concentrations of 0%, 2.5%, 5% and 7.5% that sprayed onto the surface of guava (Psidium guajava) and observed their effect on the fruit fly. Parameters observed are the number of pupae and the number of adult flies. Data were analyzed by analysis of variance (F test) α = 0.05 followed by Least Significant Difference (LSD). Results showed that the higher the concentration of extract tested, the stronger its effect on the number of pupae and adult flies. This research suggests that ethanolic extract of M. calabura leaves could perhaps be good alternatives to synthetic pesticides.

Abstract

Kombucha adalah minuman fermentasi yang terbuat dari teh manis dan difermentasi oleh koloni bakteri dan ragi, dikenal sebagai SCOBY (Symbiotic Culture of Bacteria and Yeast). Minuman ini dikenal memiliki berbagai manfaat kesehatan, seperti meningkatkan sistem pencernaan dan kekebalan tubuh. Dusun Gamping Lor, Sleman, Yogyakarta, merupakan pemukiman padat penduduk yang sebagian besar anggotanya adalah ibu rumah tangga. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memberdayakan ibu-ibu rumah tangga di Dusun Gamping Lor melalui pelatihan pembuatan kombucha. Pelatihan ini dirancang dengan kombinasi teori dan praktik, meliputi pengenalan kombucha, proses fermentasi, dan teknik pemasaran. Hasil pelatihan menunjukkan bahwa seluruh peserta (100%) merasa pelatihan ini bermanfaat, memberikan wawasan baru dalam pengolahan makanan, dan sebagian besar peserta (80%) tertarik untuk memperdalam pengetahuan mereka tentang kombucha. Selain itu, 75% peserta menunjukkan minat untuk menjual produk kombucha. Pelatihan ini berhasil meningkatkan pengetahuan dan keterampilan peserta, serta memotivasi mereka untuk mengembangkan potensi ekonomi keluarga melalui produksi kombucha.

Abstract

Botanical extracts have been reported as biopesticides, which act as antifeedants, insect growth regulators and repellents. As biopesticides, botanical extracts offer a more sustainable solution to pest control as chemical pesticides have a residual problem and are prone to pest resistance. The present study was conducted to evaluate the efficacy of waru leaves extract to control S. litura larvae in vitro conditions. The extract was prepared by maceration with methanol as a solvent. Third instar larvae of S. litura were randomly grouped into 6 treatments consisting of 0%, 3%, 6%, 9%, 12% and positive control (Lannate). Each treatment consisted of 3 replications. Leaf Dipping method was used in the treatment. Observations were made for up to 4 days. The parameters observed were changes in larval morphology, mortality, LC50 and LT50. Data were analyzed using One Way ANOVA (followed by LSD) and Probit analysis. The results showed that the highest activity of waru leaf extract was found at a concentration of 12%, which caused a mortality of 53% larvae. The LC50 value was at a concentration of 11.72%, and the LT50 value was 3.287. It can be concluded that the leaf extract has the potential to control S. litura larvae.

Abstract

The application of botanical pesticide is a positive long term approach to control S. frugiperda. Shallot leaves contain acetogenin compound, hence it has the potential to become botanical pesticide. This study is aimed at finding out the effects of ethanolic extract of shallot leaves on S. frugiperda larvae in vitro. Extract is prepared using maceration method with ethanol solvent. The method of treatment is Leaf Dipping. The study applies Completely Randomized Design with concentration of shallot leaf extract as treatment at 0 ppm, 250 ppm, 500 ppm, 750 ppm dan 1000 ppm. Each treatment consists of four repetitions. Examination is conducted for 24 hours. Examination parameter is mortality of larvae and LC50. Data are analyzed with One Way ANOVA (proceeded with LSD) and Probit analysis. The results suggest that shallot leaf extract at the concentration of 1000 ppm appears to be the most effective on the mortality of larvae. The obtained LC50 value is 263,02 ppm. The study indicates that shallot leaf extract can be applied as an alternative synthetic insecticide to control ini S. frugiperda.

Abstract

Productivity and quality of crops can be increased through polyploidy plants induced by antimitotic compounds such as vinka alkaloids.The use of vinka alkaloids has never been applied to Sword bean (Canavalia ensiformis), a tropical legume belonging to the Fabaceae family. This study aimed to determine the effects of vinka alkaloids treatment on the morphological characters of Sword bean. The treatment consist of four different vinka alkaloids concentrations (0.5%, 1.00%, 1.50%, 2.0%, and untreated (0.0%) act as control. The plants were arranged in a completely randomized design. Treated plants were characterized based on morphological traits such as plant height, leaf area and dry seed weight. The results obtained revealed significant difference (p≤0.05) in the morphological traits of the treated plants when compared with the control. Overall, 2.0% vinka alkaloids concentration resulted in higher average plant height by 193.8 ± 1.86, leaf area increments by 88.6 ± 5.1 (left leaf), 115.1 ± 4.7 (middle leaf), 86.2 ± 3.8 (right leaf) and the dry seed weight by 1.7 ± 3.6. The improvement of the traits is concentration dependent and increases with increment in vinka alkaloids concentration. Thus, we suggested that 2.0% concentration should be employed in improving Sword bean growth and yield.

Abstract

Fungal diversity is high in Indonesia, one of which is Scleroderma sp. Scleroderma forms a symbiotic relationship with Gnetum gnemon. Its fruiting body is puff-ball shaped, and its gleba can be consumed because of its taste and nutritious. Study on the Scleroderma’s diversity in Purworejo Regency has not been done. In this study, morphological characteristics were used as main identification character. Scleroderma samples were collected from Grabag, Kemiri, and Kaligesing and then observed their morphology and spore characteristics. Morphological traits observed on fruit body shape (globose and kidney-shaped); and ornamentation on peridium layer (cracked, nodule and peeling). Chemical content, temperature, and humidity of the soil were also observed as supporting data.
