Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh variasi formulasi pakan Black soldier fly (BSF) Hermetia illucens yang terdiri dari limbah ikan dan sayuran terhadap kandungan nutrisi larva BSF. Jenis penelitian ini adalah eksperimen dengan menggunakan 4.000 larva BSF yang telah memasuki fase instar dua. Pemeliharaan larva BSF dilakukan selama 15 hari. Pemberian pakan dilakukan sekali dalam 2-3 hari. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 3 perlakuan dan 3 kali ulangan. Perlakuan A yaitu 10% limbah ikan : 90% limbah sayuran, B yaitu 20% limbah ikan : 80% limbah sayuran, C yaitu 30% limbah ikan : 70% limbah sayuran. Parameter yang diamati yaitu Kandungan nutrisi dalam tubuh larva BSF dianalisis menggunakan analisis proksimat. Data hasil analisis proksimat dianalisis menggunakan analysis of variance (ANOVA) dan Uji lanjut Duncan dengan taraf kepercayaan 95%, Hasil penelitian menunjukkan perlakuan C dengan 30% limbah ikan dan 70% limbah sayur memberikan hasil yang terbaik dengan kandungan protein tertinggi dibandingkan perlakuan A dan B. Maka dapat disimpulkan bahwa variasi formulasi pakan berpengaruh signifikan terhadap kandungan nutrisi larva BSF Hermetia illucens. Kata kunci: Formulasi pakan, Nutrisi, Hermetia illucens.This study aims to determine the effect of variations in the feed formulation Black soldier fly (BSF) Hermetia illucens consisting of fish and vegetable waste on the nutritional content of BSF larvae. This type of study is an experiment using 4,000 BSF larvae that have entered the instar phase two. The maintenance of BSF larvae is carried out for 15 days. Feeding is carried out once in 2-3 days. This study used a Randomized Group Design (RAK) with 3 treatments and 3 repeats. Treatment A is 10% fish waste: 90% vegetable waste, B is 20% fish waste: 80% vegetable waste, C is 30% fish waste: 70% vegetable waste. The observed parameters, namely the content of nutrients in the body of BSF larvae was analyzed using proximate analysis. The data from the proximate analysis were analyzed using analysis of variance (ANOVA) and Duncan's advanced test with a confidence level of 95%, the results of the study showed that the behavior ofC with 30% of fish waste and 70% of vegetable waste gave the best results with the highest protein content compared totreatments A and B.   to the nutritional content of the larvae of BSF Hermetia illucens.Keywords: Feed formulation, Nutrition, Hermetia illucens.

Abstract

Abstrak. Tujuan penelitian ini: mengembangkan media pembelajaran tutorial pada mata pelajaran Graphic Design pada siswa yang mengikuti pembelajaran tutorial, mengetahui  kepraktisan dan keefektifan dari media pembelajaran tutorial yang telah dihasilkan. Jenis Penelitian ini adalah penelitian dan pengembangan. Model pengembangan yang digunakan dalam penelitian ini adalah model ADPE yang terdiri dari empat tahapan yaitu: analisis, desain,pengembangan danevaluasi. Model  ini merupakan hasil modifikasi ADDIE dan Borg&Gall. Data dianalisis menggunakan statistik deskriptif dengan cara mendeskripsikan data yang telah terkumpul dari hasil pengembangan, penilaian validator dan hasil pengamatan melalui instrumen. Data instrumen diperoleh dari hasil uji coba produk yang terbagi dalam tiga kategori, uji coba one to one dengan subjek sebanyak tiga orang merupakan tahap pertama. Hasil revisi berdasarkan data analisis ujicoba tahap pertama  selanjutnya dilakukan ujicoba kelompok kecil dengan subjek sebanyak sepuluh orang. Ujicoba terakhir adalah uji coba diperluas yang melibatkan subjek penelitian sebanyak dua puluh lima orang untuk mendapatkan data akhir dari penelitan terhadap media hasil pengembangan.Hasil penelitian menunjukkan bahwa:Berdasarkan hasil validasi ahli dengan rerata presentase 100% menunjukan hasil pengembangan media pembelajaran tutorial di SMK berada pada kategori sangat valid, hasil analisis respon gururerata presentase 94,44% dan peserta didik dengan rerata presentase 84,18% menunjukkan  pengembangan media pembelajaran tutorial pada mata pelajaran Graphic Design berada pada kategori praktis digunakan, sedangkan media pembelajaran tutorial menunjukkan efektif digunakandi SMK Negeri 2 Gowa berdasarkan hasil tes belajar siswa kelas X TKJ yang mengalami peningkatan. Kata Kunci: Media, Pengembangantutorial, Valid, Praktis Dan Efektif

Abstract

This study aims to determine the effect of the addition of mealworm frass and molasses on the proximate value ofwhite oyster mushrooms. This type of research was an experiment using a completely randomized design (CRD)consisting of four treatments with three replications each. Test parameters include water content, ash content, crudeprotein, crude fat and crude fiber. Proximate data on water content, ash content, crude protein, crude fat and crudefiber were analyzed using analysis of variance (ANOVA) and Tukey's follow-up test with a 95% confidence level.The results showed that treatment with frass and frass molasses had an effect on water content, ash content, crudeprotein, crude fat, and a decrease in fiber content. Therefore, it can be concluded that the addition of mealwormfrass and molasses affects the proximate value of the resulting oyster mushrooms.

Abstract

Nitrogen-fixing bacteria are bacteria that have an important role in the process of nitrogen assimilation in the soil. Nitrogen-fixing bacteria consist of symbiotic and non-symbiotic nitrogen-fixing bacteria found abundantly in the rhizosphere. This research seeks to isolate, characterize, and evaluate the ability of rhizosphere bacteria in maize on tropical marginal soils to excrete ammonium. Isolate nitrogen-fixing bacteria using nitrogen-free bromothymol blue (NFB) medium. Soil samples were inoculated on solid NFB medium using the spread method and then incubated at 30˚C  for 6-7 days to observe nitrogen-fixing bacterial growth and were then characterized. The physiological characteristics of nitrogen-fixing bacterial isolates from the maize rhizosphere that were observed include temperature, pH, and salinity. A temperature resistance test was conducted to determine the resistance of nitrogen-fixing bacterial isolates to temperature. Ammonium excretion test using the spectrophotometric method. Six nitrogen-fixing bacteria isolates had been identified molecularly were Rhizobium pusense (LC585441.1), Beijerinckia fluminensis (MG547695.1), Microbacterium neimengense (LC430078.1), Microbacterium binotii (MN428150), Rhizobium pusense (MK542929.1) and Rhizobium sp. strain FNF3 (MH910714.1). The results of the ammonium excretion test showed that the highest concentration was produced by Microbacterium binotii at 42.0 μM, Microbacterium neimengense at 41.0 μM while for Beijerinckia fluminensis species, Rhizobium sp strain FNF3, and 2 Rhizobium pusense isolates respectively 38.8 μM, 38.6 μM, 38.0 μM, and 36.2 μM.
