Judul: Analisis Kepuasan Konsumen Kecap Manis Bango di Kabupaten Bekasi
Abstrak: Kecap Bango merupakan salah satu pionir dalam industri kecap manis yang menguasai sebagian besar pangsa pasar. Berdasarkan survei Top Brand Award, indeks kecap Bango berturut-turut mengalami penurunan dari tahun 2020 hingga 2023. Perlu adanya upaya peningkatan kinerja untuk memenuhi kebutuhan konsumen dan meningkatkan daya saing sehingga dapat bertahan memimpin pasar. Kabupaten Bekasi merupakan wilayah dengan volume konsumsi kecap tertinggi di Jawa Barat. Penelitian ini bertujuan untuk mengidentifikasi karakteristik konsumen dan proses keputusan pembelian, menganalisis tingkat kepuasan, dan menganalisis kinerja atribut yang memengaruhi kepuasan konsumen kecap Bango di Kabupaten Bekasi. Penelitian ini menggunakan data primer yang diperoleh melalui survei daring dengan sampel 130 responden. Data dianalisis menggunakan analisis deskriptif, Customer Satisfaction Index (CSI) dan Importance Performance Analysis (IPA). Hasil penelitian menunjukkan sebagian besar responden adalah perempuan muda bersuku Jawa dan memiliki keputusan pembelian otonom. Nilai CSI kecap Bango sebesar 82.89 persen yang berada pada kriteria “sangat puas”. Berdasarkan hasil IPA, atribut keterjangkauan harga dan rasa manis merupakan atribut yang perlu perbaikan kinerja guna meningkatkan kepuasan konsumen., Bango is one of the pioneers in the sweet soy sauce industry which controls most of the market share. Based on the Top Brand Award survey, the Bango soy sauce index has decreased successively from 2020 to 2023. Efforts are needed to improve performance to meet consumer needs and increase competitiveness so that it can continue to lead the market. Bekasi Regency is the region with the highest volume of soy sauce consumption in West Java. This study aims to identify consumer characteristics and purchase decision processes, analyze satisfaction levels, and analyze performance attributes that affect consumer satisfaction of Bango soy sauce in Bekasi Regency. This study uses primary data obtained through an online survey with a sample of 130 respondents. Data were analyzed using descriptive analysis, Customer Satisfaction Index (CSI) and Importance Performance Analysis (IPA). The results showed that most of the respondents were young Javanese women and have an autonomous purchasing decision. The CSI value of Bango soy sauce was 82.89 percent which was in the "very satisfied" criteria. Based on the IPA results, the attributes of affordability and sweet taste are the attributes that need to be improved in order to increase customer satisfaction.

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
