Judul: Pengembangan Produk Patty Vegetarian Berbahan Dasar Tempe Kacang Merah (Phaseolus vulgaris L.) dan Jamur Tiram (Pleurotus ostreatus) dengan Penambahan Daun Torbangun (Coleous amboinicus L.).
Abstrak: Tren konsumsi pangan vegetarian saat ini semakin diminati oleh masyarakat dengan berbagai penyebab seperti kepercayaan, kebutuhan untuk hidup sehat, hingga alergi terhadap pangan hewani tertentu. Vegetarian adalah seseorang yang tidak mengonsumsi daging, unggas, atau ikan. Tujuan utama penelitian ini adalah mengembangkan patty vegetarian berbahan dasar tempe kacang merah (Phaseolus vulgaris L.) dan jamur tiram (Pleurotus ostreatus) dengan penambahan daun torbangun (Coleous amboinicus L.) sebesar 0% (F0), 2% (F1), 2.5% (F2), dan 3% (F3). Patty vegetarian formula terpilih yaitu dengan persentase penambahan daun torbangun sebesar 2.5% (F2). Patty vegetarian formula terpilih mengandung kadar air 65.16% (b.b), kadar abu 3.31% (b.k), kadar lemak 8.13% (b.k), protein 15.67% (b.k), karbohidrat 72.86% (b.k), serat pangan 12.67% (b.k), zat besi 1.24 mg, kalsium 46.39 mg dan magnesium 24.21 mg. Asam amino pembatas pada patty vegetarian formula terpilih adalah metionin dengan kadar sebesar 0.5 mg protein.

Judul: Development of Vegetarian Nugget Based on Red Beans Flour (Phaseolus vulgaris L.) and Soybean Tempeh
Abstrak: Diet vegetarian merupakan salah satu diet populer berisiko tinggi kekurangan zat gizi protein, zat besi, seng serta B12 yang dapat menyebabkan anemia. Kacang merah memiliki keunggulan pada zat besi dan serat pangan, sedangkan tempe memiliki keunggulan pada B12 dan keduanya merupakan sumber protein nabati yang baik. Tujuan penelitian ini untuk melakukan pengembangan vegetarian nugget berbasis tepung kacang merah dan tempe kedelai berdasarkan formula terbaik. Metode yang digunakan yaitu Rancangan Acak Lengkap (RAL) dengan perlakuan variasi konsentrasi penambahan campuran tepung kacang merah dan tempe kedelai. Nugget formula terpilih yaitu F1 (tepung kacang merah 20%, tempe kedelai 80%) berdasarkan uji organoleptik, analisis fisik, dan kandungan gizi. Hasil analisis fisik (kekerasan) nugget terpilih memiliki kekerasan terendah dibanding formula lainnya sejalan dengan uji mutu hedonik kekerasan yaitu lunak. Kontribusi nugget terhadap ALG kelompok umum yaitu energi 7,7%, protein 21,9%, lemak 4,0%, karbohidrat 6,9%, serat 23,8%, zat besi 85,7%, serta B12 8% dari total kebutuhan sehari. Kandungan gizi nugget formula terpilih yaitu air 49,85 g/100g, abu 2,38 g/100g, lemak 3,36 g/100g, protein 16,36 g/100g, karbohidrat total 28,04 g/100g, zat besi 23,56 mg/100g, serat pangan 8,94 g/100g, dan B12 0,24 μg/100g. Produk ini memenuhi klaim sebagai makanan sumber protein, tinggi serat pangan, dan tinggi zat besi., Vegetarian diet is one of the popular diets with a high risk of nutritional deficiencies of protein, iron, zinc and B12 which can cause anemia. Red beans have advantages in iron and dietary fiber, while Tempe has advantages in B12 and both are good sources of vegetable protein. The purpose of this study was to develop vegetarian nuggets based on red bean flour and soybean tempeh based on the best formula. The method used is Completely Randomized Design (CRD) with the concentration variation of the addition of a mixture of red bean flour and soybean tempeh. The selected formula was F1(20% red bean flour: 80% soybean tempeh) based on organoleptik tests, physical analysis, and nutritional content. The results of the physical analysis (hardness) of the selected nugget have the lowest hardness compared to other formulas in line with the hedonic quality test of hardness, which is soft. The contribution of nuggets to general group RDI is 7,7% energy, 21,9% protein, 4,0% fat, 6,9% carbohydrate, 23,8% fiber, 85,7% iron, and 8% B12 of daily needs. The nutritional content of the selected formula nugget is water 49,85 g/100g, ash 2,38 g/100g, fat 3,36 g/100g, protein 16,36 g/100g, total carbohydrates 28,04 g/100g, iron 23,56 mg/100g, dietary fiber 8 ,94 g/100g and B12 0,24 μg/100g. This product fulfills the claim of being a high-protein, high-fiber, and high-iron food.

Judul: Algorithm construction of HLI hash function
Abstrak: Cryptography is a study of mathematical techniques related to aspects of information security regarding on confidentiality, data integrity, entity authentication, and data origin authentication. Data integrity is a service, which is associated with the conversion of data carried out by unauthorized parties. To maintain data integrity, one can use hash functions. An hash function is a computationally efficient function to map an arbitrary length bitstring to a fixed length bitstring called as hash value. The use of hash function in maintaining the information integrity and authentication is in digital signatures, virus protection, and software distribution. Illustration of the hash function in the integrity and authentication of information that is emailed as follow. The sender sends the information and hash value to the recipient. If the hash value of the information is equal to the hash value that is sent by the sender, then information has not been changed. Otherwise the information has been changed. An hash function has two properties, one way and collision resistance. An hash function is called one way if it is computationally infeasible to find any input such that when given any hash value . Meanwhile an hash function is called collision resistant if it is computationally infeasible to find any two inputs where such that . The purpose of this study is to construct a HLI hash function algorithm, to analyze the speed and security of the hash functions as a results of construction. Furthermore, it is to compare it with SWIFFT. Hash function is constructed based on the result of algebraic operations on modular polynomial ringwith . Modular polynomial ring noted as is a set of all polynomials of degree at most with coefficients in . can be represented as a set of integer vector of modulo in dimension . So, it is simple to implement in a computer. In vector operations, is lattice . Furthermore, alattice that is defined from certain polynomial ring is called ideal lattice. HLI hash function is consists of addition and multiplication algorithm in the ring. Addition algorithm consists of sumation operations of modulo and multiplication consists of multiplication operations of modulo . Generally, algorithm of HLI hash function consists of multiplication operations of modulo and addition operations of modulo . However, if the input is binary number then multiplication algorithm only consists of multiplication operation of modulo , so algorithm of HLI hash function consists of multiplication operations of modulo and addtion operations of modulo . An hash function is secured if it has two properties, i.e., one way and collision resistance. HLI hash function hash is one way, it is following the proof of Micciancio. It is has collision resistant because of polynomial is irreducible over and monic. Moreover, it is proved that for every unit vector , the vector is small vector. If the input of hash function is a binary number then HLI hash function only involves addition operations of modulo . So the time that used almost same with SWIFFT. The excellence of HLI hash function is the key size smaller than SWIFFT. This effect on
