Ekstrak buah semu jambu monyet (EBSJM) sebagai bumbu marinasi menjadi salah satu aplikasi pemanfaatan jambu monyet di bidang pangan. Tujuan penelitian ini adalah menentukan level optimum EBSJM sebagai pensubstitusi saus tomat dalam formula bumbu marinasi ditinjau dari karakteristik fisikomikia dan hedoniknya. Empat level konsentrasi EBSJM dengan lima kali perulangan (0, 5, 10, dan 15%) dari proporsi saus tomat (v/v) ditetapkan dalam formula bumbu marinasi untuk menu steak. Produk bumbu steak untuk masing-masing formula selanjutnya dikarakterisasi fisikokimianya. Uji hedonik dilakukan dengan mengaplikasikan bumbu pada daging ayam yang diolah sebagai steak. Substitusi EBSJM pada saus tomat mempengaruhi karakteristik fisikokimia (viskositas, pH, kadar air, dan total padatan) bumbu marinasi dan karakteristik hedonik (rasa dan tekstur) pada steak sebagai hasil aplikasi dari bumbu tersebut. Viskositas dan total padatan makin meningkat sedangkan kadar air makin menurun pada substitusi lebih dari 5% (p<0,05). Penurunan pH bumbu makin bertambah seiring dengan penambahan substitusi hingga 10% (p<0,05). Uji hedonik menunjukkan substitusi 5% menghasilkan steak ayam yang paling disukai dari segi tekstur dan rasa (p<0,05). Substitusi saos tomat dengan EBSJM 5% menghasilkan produk bumbu marinasi untuk steak yang kental, asam, pekat dan paling disukai. Kata kunci : Ekstrak; bumbu; jambu monyet; marinasi Optimation on the Substitution of Tomato Sauce with Cashew Apple Extract in Formulation of Steak Marinade Seasoning ABSTRACTExtracts of cashew apple (EBSJM) as marinade seasoning is one of the applications of cashew apple utilization in the food sector. Study was aimed to determine the optimum level of EBSJM as a substitute for sauce in the marination seasoning formula reviewed from its physical and hedonic characteristics. Four levels of EBSJM concentration with five iterations (0, 5, 10, and 15%) of the sauce proportion (v/v) was defined in the marinade seasoning for steak. Steak seasoning products for each formula were further characterised by physicalochemistry. EBSJM substitution to tomato sauce affected the viscosity, pH, moisture content, and total solids of marinade seasoning and hedonic characteristics (taste and texture) in the steak as a result of the application of the seasoning. Viscosity and total solids increased while water levels decreased at substitutions by more than 5% (p<0.05). The decrease in seasoning pH increased in line with the addition of substitutions up to 10% (p<0.05). Hedonic tests showed a 5% substitution resulting in the most preferred chicken steak in terms of texture and taste (p<0.05). The substitution of tomato sauce with EBSJM 5% obtained the marinade products for steaks that were dense, sour, concentrated, and most preferred.

This study aimed to: 1) identify fish species found in Bayawan River; 2) determine fish abundance and species composition in three segments of the river; 3) characterize physico-chemical and hydrological parameters of the river; and 4) correlate fish abundance and diversity with the physico-chemical and hydrological characteristics of Bayawan River. The fishes of Bayawan River in Negros Oriental, central Philippines were assessed for three sampling months (December 2018-February 2019). Abundance and diversity of fishes were quantified in relation to physico-chemical and hydrological parameters. The data were analyzed using Shannon-Wiener Diversity Index (Hˈ), Margalef’s Index (species richness), Principal Component Analysis (PCA), and Canonical Correspondence Analysis (CCA). The Shannon-Weiner Diversity Index (Hˈ) across sampling months ranged from 2.3-3 showing a relatively diverse ecosystem. However, the number of species decreased from December 2018 to February 2019 (27 to 15 species). Twenty six (92.9%) of the fish species are marine species that spend only part of their life in freshwater while two species (7.1%) are truly freshwater species. Generally, the ichthyofauna consists of 28 species belonging to 20 families and were dominated by families Leiognathidae and Carangidae (14.3%). Most abundant species were Deveximentum megalolepis (125), Eubleekeria jonesi (107) followed by Oreochromis niloticus (48) and the rest were represented by 40 individuals and below. It is recommended that future studies should cover temporal differences, covering the wet and dry season.Keywords: diversity; fishes; limnology; lotic; Negros Island KELIMPAHAN DAN KEANEKARAGAMAN IKAN DI SUNGAI BAYAWAN, NEGROS ORIENTAL, FILIPINAABSTRAKPenelititan ini bertujuan untuk: 1) mengidentifikasi spesies ikan yang ditemukan di Sungai Bayawan; 2) menentukan kelimpahan ikan dan komposisi spesies di tiga segmen sungai; 3) mengkarakterisasi parameter fisika-kimia dan hidrologis sungai; dan 4) mengkorelasikan kelimpahan dan keanekaragaman ikan dengan karakteristik fisika-kimia dan hidrologis Sungai Bayawan.

Penelitian ini bertujuan untuk mengevaluasi intensitas serangan akibat hama pemakan daun setelah aplikasi ekstrak daun kirinyuh pada tanaman sawi. Penelitian ini dilaksanakan di lahan percobaan di Kelurahan Lansot Kecamatan Tomohon Selatan Kota Tomohon pada bulan Desember 2018 – Februari 2019. Penelitian ini menggunakan rancangan acak lengkap (RAL) yang terdiri dari 4 perlakuan konsentrasi ekstrak daun kirinyuh yaitu K0 (kontrol) = 0 g/L air, K1 = 100 g/L air, K2 = 200 g/L air, dan K3 = 300 g/L air. Intensitas serangan diamati berdasarkan luas area daun yang dirusak oleh hama pemakan daun pada daun sawi setelah aplikasi ekstrak daun krinyuh. Hasil penelitian menunjukkan bahwa pemberian ekstrak daun kirinyuh berpengaruh nyata terhadap intensitas serangan pada tanaman sawi dan konsentrasi ekstrak daun kirinyuh yang dapat menekan serangan hama pemakan daun yaitu yang tertinggi pada perlakuan K3 (300 g/L air).Kata kunci: Tanaman sawi (Brassica juncea L.), intensitas serangan, tumbuhan kirinyuh (Chromolaena odorata) THE ATTACK INTENSITY DUE TO LEAF-EATING PESTS AFTER APPLICATION OF KIRINYUH (Chromolaena odorata L.)
