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 NPK Fertilizer on The Growth and Yield of Vietnamese Coriander (Persicaria odorata)
Abstrak: Kesum (Persicaria odorata) merupakan tanaman terna tahunan yang memiliki banyak manfaat dalam bidang kesehatan dan kuliner. Pembudidayaan tanaman kesum tidak lepas dari peran media tanam sebagai penyedia hara untuk menyokong pertumbuhan tanaman kesum. Salah satu cara untuk memenuhi ketersediaan hara adalah dengan menambahkan pupuk anorganik. Tujuan dari penelitian ini mempelajari pertumbuhan vegetatif dan produktivitas tanaman kesum dengan dosis pupuk NPK 16:16:16 yang berbeda. Penelitian dimulai dari bulan Januari hingga bulan April 2024 di Gunung Batu, Bogor. Penelitian menggunakan metode rancangan acak kelompok dengan satu faktor. Faktor perlakuan berupa dosis pupuk NPK 16:16:16 yang berbeda, yaitu: 0 (kontrol), 2, 4, dan 6 g/polybag. Penelitian menggunakan tiga ulangan setiap satuan percobaan terdiri dari dari tiga polybag dan hasil analisis ragam menggunakan ANOVA serta uji lanjut DMRT dengan a 5%. Hasil penelitian menunjukkan pemberian dosis pupuk NPK yang berbeda tidak memberi pengaruh nyata terhadap pertumbuhan vegetatif dan produksi tanaman kesum. Pemberian dosis pupuk tertinggi dengan dosis 6 g per polybag memiliki hasil tertinggi pada semua peubah kecuali jumlah daun pada 8 MST., Vietnamese coriander is a perennial herb known for its numerous benefits in both health and culinary applications. Vietnamese coriander cultivation is inseparable from the role of growing media as a nutrient provider to support the growth of Vietnamese coriander. One way to meet nutrient availability is by adding fertilizer. The research aims to study the growth and productivity of Vietnamese coriander with different doses of NPK 16:16:16 fertilizer. The research started from January to April 2024 in Gunung Batu, Bogor, Indonesia. The study used a randomized complete block design with one factor. The treatment NPK fertilizer, namely: 0(control), 2, 4, and 6 g/polybag. The research used three replications, each unit consisted of 3 polybags, and the results were analyzed for variance using ANOVA and further tested with DMRT at a 5% significance level. The research showed that giving 6 g/polybag NPK significantly increased the leaf area and color of the Vietnamese coriander as a leaf vegetable plant. NPK fertilizer at a dose of 6 g/polybag had the highest results for all variables except the leaf number at 8 WAP. However, giving different doses to Vietnamese coriander did not affect the overall weight of Vietnamese coriander plants.

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
