Judul: Kualitas Udara Selama Pengangkutan Sapi di Kapal Motor Camara Nusantara 3
Abstrak: Kapal Camara Nusantara 3 merupakan moda transportasi laut yang saat ini diterapkan untuk pengiriman ternak hidup ke berbagai wilayah. Informasi mengenai standar kualitas udara selama proses pengangkutan sapi menggunakan kapal di Indonesia belum banyak dilakukan. Penelitian ini bertujuan untuk menganalisis dan menginformasikan kualitas udara selama proses pengangkutan sapi, serta strategi peningkatan kualitas udara di KM Camaara Nusantara 3. Penelitian ini dilakukan di KM Camara Nusantara 3 dari Pelabuhan Tenau, Kupang menuju Pelabuhan Tanjung Priok, Jakarta. Lama perjalanan yang ditempuh selama lima hari. Selama proses pengangkutan berlangsung, pengamatan yang dilakukan antara lain kondisi lingkungan kapal, mikroklimat (suhu lingkungan, kelembaban relatif, THI, dan kecepatan angin), dan produksi gas (O2, CO2, CO, NH3, dan CH4). Berdasarkan pengamatan yang dilakukan, KM Camara Nusantara 3 merupakan jenis kapal dengan Combine Deck Vessels (geladak kombinasi). Tipe sistem ventiasi yang diterapkan ada dua, yakni supply-exhaust ventilation system pada geladak A dan exhaust ventilation system pada geladak B dan C. Kondisi mikroklimat yang diamati selama proses pengangkutan meliputi: suhu lingkungan sebesar (30.48-31.49 oC); kelembaban relatif sebesar (73.13-75.24 %); nilai THI sebesar (82,63-84,08) termasuk kategori stress sedang dan berat, dan kecepatan angin sebesar (0.2-0.8 ms-1). Tingkat konsentrasi gas yang diamati selama pengangkutan meliputi: gas O2 sebesar (20.5-20.6 %); gas CO2 sebesar (475.7– 497.4 ppm); gas CO sebesar (1.2–1.4 ppm); gas NH3 sebesar (2.9–3.3 ppm); dan gas CH4 sebesar (1.5-4.9 ppm). Hasil penelitian menunjukkan kualitas udara selama proses pengangkutan sapi dari Kupang menuju Jakarta di KM Camara Nusantara 3 masih dibawah nilai ambang batas. Strategi dari segi kualitas meliputi laju aliran udara dalam kandang perlu ditingkatkan sehingga distribusi gas dan proses pertukaran udara dapat berlangsung dengan baik.

Judul: Air Quality During Cattle Transport on Camara Nusantara Ship 3
Abstrak: Camara Nusantara 3 ship is a marine transportation mode that is currently being implemented for the delivery of live livestock to various regions. There is not much information about air quality standards during the process of transporting cattle by ship in Indonesia. This study aims to analyse and inform air quality during the process of transporting cattle, as well as strategies for improving air quality at Camaara Nusantara 3 ship. This research was conducted at Camara Nusantara 3 ship from Tenau Port, Kupang to Tanjung Priok Port, Jakarta. The length of the trip is five days. During the transportation process, observations made include the ship's environmental conditions, microclimate (ambient temperature, relative humidity, THI, and wind speed), and gases production (O2, CO2, CO, NH3, and CH4). Based on the observations made, Camara Nusantara 3 ship is a type of ship with Combine Deck Vessels (combination deck). There are two types of ventilation systems, namely the supply-exhaust ventilation system on deck A and the exhaust ventilation system on decks B and C. The microclimate conditions observed during the transportation process included: ambient temperature (30.48- 31.49 oC); relative humidity (73.13-75.24 %); THI values (82.63-84.08) including moderate and heavy stress categories, and wind speed of (0.2-0.8 ms-1). The level of gas concentration observed during transportation includes O2 gas (20.5-20.6 %); CO2 gas (475.7-497.4 ppm); CO gas (1.2-1.4 ppm); NH3 gas (2.9-3.3 ppm); and CH4 gas (1.5-4.9 ppm). The results showed that the air quality during the process of transporting cattle from Kupang to Jakarta at KM Camara Nusantara 3 was still below the threshold value. The strategy in terms of quality, including the rate of airflow in the cage, needs to be improved so that the gas distribution and air exchange process can take place properly., Kapal Camara Nusantara 3 merupakan moda transportasi laut yang saat ini diterapkan untuk pengiriman ternak hidup ke berbagai wilayah.

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
