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: Pengembangan Produk Nugget Jamur Tiram Tinggi Protein Dan Kaya Serat Melalui Pemanfaatan Tepung Tempe Kacang Merah
Abstrak: Penelitian ini bertujuan untuk mempelajari pengaruh penambahan tepung tempe kacang merah dalam pembuatan nugget jamur tiram. Penelitian ini terdiri dari dua tahap. Tahap pertama penelitian pendahuluan untuk mempelajari pembuatan nugget dengan tambahan tepung tempe kacang merah yang menghasilkan produk terbaik. Tahap kedua merupakan dilakukan uji sifat fisik dan kimia, uji kandungan gizi, dan uji organoleptik. Penelitian ini menggunakan desain rancangan acak lengkap (RAL) dengan 4 taraf. Perlakuannya adalah subsitusi tepung tempe kacang merah terhadap nugget jamur tiram dengan taraf 0%, 15%, 30%, dan 45%. Berdasarkan uji organoleptik, sifat kimia dan skor penerimaan produk terpilih adalah nugget jamur tiram dengan penambahan 15% tepung tempe kacang merah. Nugget jamur tiram dengan penambahan tepung tempe kacang merah memiliki kadar air 58.68%, kadar abu 2.50%, kadar lemak 8.19%, kadar protein 7.80%, kadar karbohidrat 22.83%, kadar serat kasar 1.26% dan kadar serat pangan 7.38%. Kontribusi zat gizi nugget jamur tiram dengan penambahan tepung tempe kacang merah memberikan kontribusi energi 9.8%, protein 13 %, lemak 13.2%, karbohidrat 7.6% dan serat pangan 31.3%. Produk ini dapat diklaim sebagai pangan kaya serat.

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
