This research aims to determine the optimal probiotic concentration and to analyze the effect of addition of fermented restaurant waste meal (FRWM) in feed to growth of nile tilapia. The research was carried out from February-June 2019 at Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. This research used experimental method with a Completely Randomized Design (CRD) consisting of five treatments and three replications. The treatments given consisted of addition of 0, 10, 20, 30 and 40% of FRWM in feed. The parameters observed included changes in the nutritional value of restaurant waste, daily growth rate, survival, feed conversion ratio, and water quality. Data were analyzed using analysis of variance. and was further analyzed using Duncan’s multiple range test 5%. The results showed that the addition of 8% probiotic concentration was able to provide the best change in the nutritional quality of restaurant waste by increasing feed protein by 50.83% and decreasing crude fiber by 30.74%. The use of 30% fermented restaurant waste meal in feed gave the highest daily growth rate of 1.57% and the best feed conversion ratio of 0.57 with a survival rate ranging from 75-90%.
Organic material produced from domestic food waste can be functionalized as useful product such as fish feed by fermentation process. The fermentation process changed several properties such as nutrition content and particle size. Here, we reported the effect of fermentation process on physical properties of organic material from domestic food waste. In this study, fermented product will be conducted to become fish feed. The fermentation was performed by using commercial probiotic BIOM-S with various levels of probiotic from 0 to 10% using solid substrate fermentation method. The physical properties including nutritional content, particle size, distance between particles, and functional group of fermented organic material from domestic food waste were investigated. After fermentation, it is found that the best level of probiotic use is 8%, which are crude protein increased from 15.58% to 26.16% and crude fiber content decreased from 4.88% to 3.71%. The average particle sizes and distance between particles of fermented domestic food waste fermented by 8% probiotic were 147.723 µm and 1708.802 µm, respectively, while the functional group did not change after fermentation. The present result indicated that fermentation process effected to improve the quality of organic material from domestic food waste.
This study aims to evaluate the physical quality of fish feed pellets formulated with different concentration of fermented restaurant waste meal (FRWM). The treatments given consisted of treatment A (control, without adding FRWM), treatment B (adding FRWM 10%), treatment C (adding FRWM 20%), treatment D (adding FRWM 30%) and treatment E (adding FRWM 40%). The study was conducted from July to October 2019 at the Aquaculture Laboratory and Hatchery in Ciparanje of the Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. The parameters observed include the breaking rate test, sinking rate test, durability test, and stability test. Results showed that the use of FRWM given significant difference (p<0.05) for breaking rate and stability value. However, result showed that the sinking rate and durability value generally did Sandra et al.; AJFAR, 5(3): 1-7, 2019; Article no.AJFAR.53180 2 not show significant difference (p>0.05). The FRWM can be used up to a concentration of 30% which gives effect to the sinking rate of the fish pellet which is similar to the control fish pellet namely 0.38 cm/s while the concentration of the meal of the FRWM gives the closest value of breaking rate and stability control as much as treatment B (adding FRWM 10%) with a break rate for 19.93 hours and stability in water for 10 minutes by 91.66%, 30 minutes by 87.60%, and for 60 minutes by 75.26%. The different adding concerntration of FRWM gives effect to the quality of fish pellet while more than 10% can decrease its quality. The difference were show in all treatment in some parameters observed. Original Research Article
Pengolahan sampah merupakan wujud dari tindak lanjut dari permasalahan yang timbul dari sampah dan dapat menghasilkan produk yang bermanfaat bagi masyarakat. Produk yang dihasilkan ini dapat mempermudah pekerjaan manusia dan dapat menjadi salah satu sumber pendapatan. Untuk pengolahan limbah organik sendiri dapat menghasilkan beberapa produk seperti biogas, pupuk organik, dan maggot. Dari hasil pengolahan limbah organik menjadi maggot dapat digunakan sebagai produk pakan ikan. Penelitian ini bertujuan untuk mengetahui potensi dan pengaplikasian masyarakat Desa Gudang, Kecamatan Tanjungsari dalam mengolah limbah organik menjadi komoditas bermanfaat. Metode yang digunakan dalam mengolah data pada penelitian ini adalah analisis deskriptif dengan pendekatan kuantitatif berupa pengumpulan data dengan kuesioner. Berdasarkan data kuesioner yaitu sebanyak 30 responden yang telah berpartisipasi, mayoritas responden mengetahui apa itu limbah organik yang ditandai dengan diketahuinya pengertian, contoh, manfaat, dampak, pengolahan sampah, dan minat terhadap pengolahan sampah, tetapi pengolahan limbah organik yang dilakukan masyarakat Desa Gudang, Kecamatan Tanjungsari belum banyak dilakukan secara mandiri, dan lebih berminat untuk mengolah limbah organik menjadi pupuk kompos daripada produk lainnya karena dinilai lebih mudah dan lebih umum dibandingkan dengan produk lainnya.
Limbah pertanian lokal berupa daun ubi jalar dan ampas tahu yang berada di Desa Gudang berpotensi sebagai bahan pakan penguat untuk meningkatkan performa domba. Oleh karena itu untuk penerapannya perlu dilakukan penyuluhan dan demosntrasi plot agar dapat diadopsi oleh peternak. Kegiatan ini dlakukan secara bertahap, yaitu 1) observasi lapangan dan menghimpun kepustakaan, 2) penyuluhan, 3) demonstrasi plot. Penyuluhan telah dilakukan di SD Cikupa Desa Gudang Kecamatan Tanjungsari yang dihadiri oleh 24 orang peserta, lalu dilanjutkan dengan demonstrasi plot. Hasil menunjukkan bahwa terjadi peningkatnya pengetahuan peternak dan masyarakat tentang potensi bahan pakan terurama bahan pakan penguat berupa daun ubi jalar dan ampas tahu. Uji coba di lapangan telah menunjukan bahwa domba yang diberi daun ubi jalar dan ampas tahu terjadi peningkatan bobot badan harian sebesar 55,8 g/hari. Kesimpulan, penyuluhan dapat meningkatkan pengetahuan peserta tentang bahan pakan dan performa domba meningkat dengan pemberian daun ubi jalar dan ampas tahu sebagai bahan pakan penguat.
