Judul: Pertumbuhan Vegetatif dan Produktivitas Tanaman Kesum (Persicaria odarata) pada Kombinasi Media Tanam dan Jenis Pupuk Kandang yang Berbeda
Abstrak: Kesum (Persicaria odorata) adalah tanaman rempah yang memiliki banyak manfaat dan mudah dalam proses pembudidayaannya. Dalam sebuah pembudidayaan tanaman termasuk kesum, peran dari media tanam dan penyedia unsur seperti pupuk kandang sebagai pendukung pertumbuhan menjadi sangat penting. Tujuan dari penelitian ini mempelajari pertumbuhan vegetatif dan mengetahui produktivitas tanaman kesum (Persicaria odorata) pada kombinasi media tanam dan jenis pupuk kandang yang berbeda. Penelitian dimulai dari bulan Januari 2023 hingga bulan April 2023 di Gunung Batu, Bogor. Penelitian menggunakan metode rancangan kelompok lengkap teracak dua faktor. Faktor pertama yakni kombinasi media tanam, yaitu: topsoil, topsoil + arang sekam (1:1 v/v), topsoil + kompos (1:1 v/v), dan topsoil + cocopeat (1:1 v/v). Faktor kedua yakni jenis pupuk kandang, yaitu: tanpa pukan, pukan sapi, pukan kambing, pukan ayam pedaging, dengan dosis pukan 100 g/polybag. Penelitian menggunakan tiga ulangan, dan hasilnya dianalisis ragam menggunakan ANOVA serta uji lanjut DMRT dengan α 5%. Hasil percobaan menunjukkan seluruh jenis kombinasi media tanam baik menggunakan pupuk kandang ataupun tidak, dapat digunakan untuk membudidayakan tanaman kesum., The Kesum plant (Persicaria odorata) is a spice with many benefits and is easy to cultivate. In the cultivation of plants, including kesum, the role of the planting medium and providers of elements such as manure as growth support is very important. This study aims to study vegetative growth and determine the productivity of kesum plants (Persicaria odorata) in different combinations of planting media and types of manure. The study runs from January 2023 to April 2023 in Gunung Batu, Bogor. The study used the design of a randomized complete group with two factors. The first factor is the combination of planting media, namely: topsoil, topsoil + rice hull charcoal (1:1 v/v), topsoil + compost (1:1 v/v), and topsoil + cocopeat (1:1 v/v). The second factor is the type of manure fertilizer: without manure, cow manure, goat manure, and chicken manure, with a dosage of manure fertilizer 100 g/polybag. The study used three repeats, and the results were analyzed variously using ANOVA, and DMRT further tests with α 5%. The result showed that all types of combined planting media, whether using manure or not, can be used to cultivate kesum plants.

Judul: The Effect of Goat Manure Fertilizer on The Growth and Yield of Kesum (Persicaria odorata)
Abstrak: Tanaman kesum (Vietnamese mint) merupakan tanaman terna yang dimanfaatkan masyarakat sebagai bumbu penyedap dan obat. Peningkatan produksi tanaman kesum harus didukung budidaya optimum, salah satunya pemberian dosis pupuk kandang yang tepat. Penelitian ini bertujuan untuk mempelajari pengaruh dosis pupuk kandang kambing terhadap pertumbuhan dan hasil tanaman kesum. Penelitian dilaksanakan pada bulan Februari hingga April 2024 di Gunung Batu, Bogor Barat, Jawa Barat (6°35'36"S 106°46'21"E) dengan ketinggian ± 231 mdpl. Rancangan percobaan yang digunakan yaitu rancangan acak kelompok (RAK) faktor tunggal dengan 3 ulangan. Perlakuan dosis pupuk terdiri dari 5 taraf yaitu 0, 10, 20, 30 dan 40 g tanaman-1 sehingga terdapat 15 satuan percobaan. Hasil penelitian menunjukkan bahwa perlakuan dosis pupuk kandang kambing berpengaruh nyata terhadap pertumbuhan dan hasil tanaman. Dosis pupuk organik kandang kambing sebesar 40 g tanaman-1 memberikan pengaruh terbaik dalam meningkatkan produksi kesum. Tidak didapat dosis optimum karena kurva respons antara dosis 0–40 g tanaman-1 dengan semua peubah masih linier positif. Perlu penelitian dengan dosis pupuk kandang kambing lebih lanjut untuk didapat dosis optimum., The Effect of Goat Manure Fertilizer on The Growth and Yield of Kesum Plants (Persicaria odorata). Supervised by Sandra Arifin and Ahmad Junaedi. Vietnamese mint is a terna plant used by the community for seasoning and medicine. Increasing the production of Persicaria odorata must be supported by optimum cultivation, one of which is giving the right dose of manure. This research aims to study the effect of goat manure doses on the growth and yield of kesum plants. The research was conducted from February to April 2024 at Gunung Batu, West Bogor, West Java (6°35'36 "S 106°46'21 "E) with an altitude of ± 231 meters above sea level. The experimental design used was a single-factor randomized group (RAK) with 3 replications. The fertilizer dose treatment consisted of 5 levels, namely 0, 10, 20, 30, and 40 g plant-1 so there were 15 experimental units. The results showed that the dose treatment of goat manure significantly affected plant growth and yield. The dose of goat manure organic fertilizer of 40 g plant-1 had the best effect in increasing kesum production. The optimum dose was not obtained because the response curve between 0–40 g plant-1 doses with all parameters was still linear. Further research with goat manure doses is needed to get the optimum dose.

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
