Judul: The Potential Of Maggot Protein Hydrolyzate (Hermetia illucens) As Antihyperglicemia
Abstrak: Penelitian ini bertujuan mendapatkan hidrolisat protein maggot terbaik dan menguji kemampuan efek hipoglikemik serta menentukan dosis optimumnya. Hidrolisat protein maggot dibuat menggunakan reaksi hidrolisis enzimatis tripsin selama 3, 5 dan 7 jam. Kemudian hasil ke 3 jenis hidrolisat protein maggot diidentifikasi menggunakan LC-MS/MS dan dibandingkan jumlah asam amino insulinotropiknya untuk memperoleh satu jenis sampel terbaik. Hidrolisat terbaik adalah yang dihidrolisis selama 7 jam karena mengandung 6 jenis asam amino insulinotropik tertinggi dari pada ke 2 sampel lainnya, sehingga dapat dilanjutkan ke uji efek hipoglikemik pada tikus hiperglikemia. Pengujian tersebut menggunakan metode oral glucose tolerance test. Sejumlah 21 ekor tikus jantan galur Sprague dawley telah digunakan pada penelitian ini, yang dikelompokkan menjadi tujuh kelompok perlakuan. Kelompok perlakuan meliputi kontrol positif, kontrol negatif, kontrol obat akarbose dan 4 kelompok perlakuan hidroliat protein, mulai dari dosis 100, 200, 300, dan 400 mg/kg berat badan. Penelitian ini menggunakan rancangan acak lengkap yang selanjutnya dianalisis dengan ANOVA dan uji beda Duncan jika terdapat pengaruh perlakuan. Pemberian hidrolisat protein maggot dengan dosis 100, 200, 300, dan 400 mg/kg bobot badan tikus menunjukkan penurunan kadar glukosa darah. Dosis 300 mg/kg berat badan merupakan dosis terbaik karena menunjukkan pengaruh hipoglikemik optimum pada tikus hiperglikemia., This study aims to obtain the best maggot protein hydrolyzate and test the ability of the hypoglycemic effect and determine the optimum dose. Maggot protein hydrolyzate was prepared using trypsin enzymatic hydrolysis reaction for 3, 5 and 7 hours. Then the results of the 3 types of hydrolyzate were identified and compared using LC-MS/MS. The best hydrolyzate is the one that is hydrolyzed for 7 hours because it contains the highest 6 types of insulinotropic amino acids, so that it can be continued to test the hypoglycemic effect in hyperglycemic rats. The test uses the oral glucose tolerance test method. A total of 21 male Sprague dawley rats were used in this study, which were divided into seven treatment group. Each treatment group had 3 replications. This study used a completely randomized design which was further analyzed by ANOVA and Duncan's difference test, if there was an effect of treatment. The administration of maggot protein hydrolyzate at doses of 100, 200, 300, and 400 mg/kg body weight of the rats showed a decrease in blood glucose levels. The dose of 300 mg/kg body weight is the best dose because it shows the optimum hypoglycemic effect in hyperglycemic rats.

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: Analisis dan Implementasi Certificate Authorities (CA) pada Public Switched Telephone Network (PSTN)
Abstrak: Secure Telephone Protocol has ability to authenticate involved party and keep the secrecy of the message sent over the protocol. The secrecy of the message archieved by using symmetric key cryptographic scheme, and authentication archieved using public key cryptographic scheme. One of several party involved in the protocol and hold an important function called Certificate Authorities or CA. CA responsible for generating public key pair for other party involved in the protocol. When CA generates public key pair, several primitive cryptographic scheme used for guarantee the security of the key. Two of them are hash function SHA-1 and El-Gamal public key scheme embedded in Digital Signature Algorithm scheme. The prototype implementing the scheme above developed using Java programming language with JCE addition from Bauncy Castle. The analysis towards implemented prototype indicates that the prototype still has some flaws to be implemented in real world.
