Abstract

Diversity of fruit flies (Diptera: tephritidae) attracted by me lure in CSG-BG germplasm carambolae plantation. Germplasm Garden (KPN) Cibinong Science Center-Botanical Garden (CSC-BG) is one of the gardens that conserve and utilizes Indonesian local germplasm, one of which is carambolae. The current problem in KPN is the attack of fruit flies (Bactrocera spp.). This study was conducted to determine the diversity of fruit flies in the KPN carambola plantation area. A total of eight traps were placed randomly in the plantation area. Each trap contained 1 mL of methyl eugenol pheromone solution. Identification of fruit flies was carried out based on three morphological differences, they were wings, abdomen, and hind legs. There were 317 fruit flies collected and separated into three species, namely Bactrocera carambolae, B. papayae, dan B. umbrosa, of which B. carambolae had a dominance index of 0.74 and abundance index of 85%. Data on the types of fruit flies can be used as primary data to determine the preparation of pest prevention efforts.

Abstract

Cheese whey, as a by product of cheese processing, contains high levels of protein and lactose, which can be utilized as a substitute medium for the growth of lactic acid bacteria (LAB) to produce flavor compounds, thereby enhancing its economic value. This study aims to identify the volatile flavor compounds present in the product resulting from de Man Rogosa and Sharpe Broth (MRSB) media with partial substitution of cheese whey (5, 15, and 30% v/v) as a source of carbon and nitrogen. The analysis was carried out using gas chromatography-mass spectrometry (GC-MS) while other observed parameters included pH, total acid, and carbon nitrogen content. The results of the study showed that the substitution of cheese whey at 5% showed the best results, and produced bioflavor compounds such as 2(5H)-furanone (almond) and benzenacetaldehyde (rose) with pH 4.57±0.012, total acid 0.88%, total carbon 15.86±0.292%, and total nitrogen 1.39±0.177%. These findings indicate that cheese whey can serve as an effective substitute for carbon and nitrogen sources in growth media to produce volatile compounds with potential flavor properties by Lactobacillus sp.

Abstract

Tandan kosong kelapa sawit (TKKS) merupakan limbah biomassa yang jumlahnya melimpah namun belum dimanfaatkan secara optimal. TKKS berpotensi dimanfaatkan kembali melalui proses pengomposan menjadi pupuk organik. Akan tetapi, kandungan lignin yang tinggi dalam TKKS menyebabkan proses pengomposan berlangsung lama, sehingga diperlukan upaya untuk menurunkan kadar lignin melalui proses biodelignifikasi. Penelitian ini bertujuan untuk mengetahui proses biodelignifikasi TKKS melalui pemanfaatannya sebagai media pertumbuhan jamur tiram putih (Pleurotus ostreatus) dan mengevaluasi efektivitas sisa baglog hasil budidaya tersebut sebagai pupuk organik. TKKS diformulasikan dalam berbagai komposisi dan digunakan sebagai bahan baglog jamur. Sisa baglog yang telah terdekomposisi selanjutnya diuji kandungan lignin, selulosa, hemiselulosa, dan rasio C/N, kemudian diaplikasikan ke tanaman cabai dan terong. Hasil menunjukkan adanya penurunan kadar lignin dan C/N rasio yang mengindikasikan terjadinya proses biodelignifikasi dan pengomposan. Aplikasi pupuk organik dari sisa baglog pada tanaman cabai dan terong menunjukkan pertumbuhan yang baik, terutama pada perlakuan dengan kandungan TKKS 75–100%. Hasil ini menunjukkan bahwa sisa baglog TKKS berpotensi besar sebagai pupuk organik yang efektif dan ramah lingkungan.
