Judul: Chemical and Physical Properties of Chemically Extracted Defatted Maggot
Abstrak: Penelitian ini bertujuan mengevaluasi kualitas kimia dan fisik dari maggot hasil ekstraksi dengan rasio pelarut yang berbeda sebagai bahan pakan alternatif sumber protein. Rancangan acak lengkap digunakan dalam penelitian ini dengan 4 perlakuan dan 3 ulangan. Perlakuan terdiri dari P0 = maggot kontrol tanpa perlakuan, P1 = maggot + larutan heksan 1:5 kg L-1, P2 = maggot + larutan heksan 1:7 kg L-1, P3 = maggot + larutan heksan 1:9 kg L-1. Parameter yang diukur pada uji fisik meliputi: warna, tekstur, bau, berat jenis, kerapatan tumpukan, kerapatan pemadatan tumpukan, sudut tumpukan, kelarutan dan pH. Parameter yang diukur pada uji kimia meliputi: kadar air, kadar abu, serat kasar, lemak kasar dan protein kasar. Data yang diperoleh dianalisis dengan ragam (ANOVA) dan dilanjutkan dengan uji Duncan jika terdapat perbedaan nyata. Penelitian ini menunjukkan hasil yang signifikan (P<0.05) pada uji kadar abu, protein kasar, lemak kasar, kerapatan tumpukan, kerapatan pemadatan tumpukan, sudut tumpukan dan pH, serta tidak signifikan (P>0.05) pada uji berat jenis dan kelarutan. Disimpulkan bahwa proses defatted maggot menyebabkan penurunan bobot rendemen, namun meningkatkan kualitas kimia dan fisik pada maggot. Proses defatted pada P1 paling efisien menghasilkan rendemen serta meningkatkan kadar nutrien pada maggot. Proses defatted juga mampu merubah karakteristik dan sifat fisik maggot pada kerapatan tumpukan, kerapatan pemadatan tumpukan, sudut tumpukan dan pH., This study aims to evaluate the chemical and physical quality of maggot extracted with different solvent ratios as an alternative feed ingredient for protein sources. Completely randomized design was used in this study with 4 treatments and 3 replications. The treatments consisted of P0 = control maggot without treatment, P1 = maggot + hexane solution 1:5 kg L-1, P2 = maggot + hexane solution 1:7 kg L-1, P3 = maggot + hexane solution 1:9 kg L-1. Parameters measured in the physical test include: color, texture, odor, true density, bulk density, tapped density, angle of repose, solubility and pH. Parameters measured in the chemical test include: ash content, crude fiber, crude fat and crude protein. The data obtained were analyzed for variance (ANOVA) and continued with Duncan's test if there was a significant difference. This study showed significant results (P<0.05) on the test of ash content, crude protein, crude fat, bulk density, tapped density, angle of repose and pH, and not significant (P>0.05) on true density and solubility tests. The defatted maggot process causes a decrease in yield weight, but increases the chemical and physical quality of the maggot. It is concluded that the defffated process in P1 is the most efficient in producing yields and increasing nutrient levels in maggot. The defffated process is also able to change the characteristics and physical properties of the maggot on the bulk density, tapped density, angle of repose and pH.

Judul: EVALUATION OF HIGH PROTEIN FEEDING IN IMPROVING MAGGOT PRODUCTIVITY
Abstrak: Maggot dapat dijadikan pakan alternatif sebagai pakan sumber protein hewani karena maggot memiliki kandungan nutrisi yang baik terutama pada kadar protein yang tinggi dan mudah ditemukan serta dikembangkan. Penelitian ini bertujuan membandingkan media tumbuh maggot dari bahan organik dengan formula pakan tinggi protein. Penelitian ini menggunakan rancangan acak lengkap dengan 2 perlakuan dan 4 ulangan. Perlakuan yang digunakan adalah P0 (pakan kontrol limbah buah dan limbah rumah tangga) dan P1 (pakan konsentrat protein tinggi). Pakan kontrol dan perlakuan protein tinggi diberikan sebanyak 13 kg selama pemeliharaan. Parameter yang diukur adalah konsumsi (gram), reduksi substrat (%), total biomassa akhir (g), jumlah maggot, bobot maggot (gram), indeks pengurangan limbah (%), FCR dan biokonversi (%). Data dianalisis menggunakan uji T sampel berpasangan. Hasil penelitian menunjukkan bahwa larva BSF yang diberi perlakuan protein tinggi berpengaruh nyata (P<0,05) dibandingkan dengan pakan kontrol untuk parameter FCR namun untuk larva yang diberi perlakuan protein tinggi nyata lebih rendah untuk parameter konsumsi pakan, reduksi substrat, total biomassa akhir, jumlah maggot, bobot maggot, WRI, dan biokonversi larva. Kesimpulan dari penelitian ini pemberian pakan maggot menggunakan media tumbuh organik dan ransum buatan protein tinggi menghasilkan performa, biokonversi, nilai pengurangan limbah yang sama. Perlakuan bahan organik dan ransum protein tinggi menghasilkan FCR yang berbeda., Maggot can be used as an alternative feed as a source of animal protein because maggot has good nutritional content, especially at high protein levels and is easy to find and develop. This study aims to compare maggot growing media from organic materials with high protein feed formulas. This study used a completely randomized design with 2 treatments and 4 replicates. The treatments used were P0 (fruit waste control feed and household waste) and P1 (high protein concentrate feed). The control feed and high protein treatment were given as much as 13 kg during maintenance. Parameters measured were consumption (grams), substrate reduction (%), final total biomass (g), maggot number, maggot weight (grams), waste reduction index (%), FCR and bioconversion (%). Data were analyzed using paired sample T test. The results showed that BSF larvae treated with high protein had a significant effect (P<0.05) compared to the control feed for FCR parameters, but the larvae treated with high protein were significantly lower for the parameters of feed consumption, substrate reduction, total final biomass, maggot number, maggot weight, WRI, and larval bioconversion. The conclusion of this study is that maggot feeding using organic growing media and high protein artificial rations produces the same performance, bioconversion, waste reduction value. The treatment of organic matter and high protein rations resulted in different FCR.

Judul: Simulasi Protokol Autentikasi Pelanggan pada Voice Privacy
Abstrak: Existing design of the telephone public network is susceptible to eavesdropping on its voice stream. Consequently, any wire taper can listen to supposedly private conversation. In order to prevent such eavesdropping, we propose a protocols and its implementation for end-to-end voice privacy authenticate as a service available for interested subscribers. Our protocols consist of customer enrollment system, customer authentication system and simulation voice privacy. Protocols that we made are adaptation from Sharif and Wijekesera journal with the title Providing Voice Privacy as a Service over the Public Telephone Network. The result of the process shows how the customer enrolls and how the system process the password, how the system authenticate customer simulate voice privacy.
