Judul: Penambahan Ekstrak Daun Bandotan (Ageratum conyzoides) pada Transportasi Sistem Tertutup Ikan Komet (Carassius auratus)
Abstrak: Kegiatan transportasi ikan hidup dalam budidaya penting untuk diperhatikan karena mempunyai kaitan yang erat dengan tingkat stres ikan pasca transportasi yang mengakibatkan meningkatkannya biaya pemeliharaan. Penelitian ini bertujuan menganalisis pengaruh penambahan ekstrak daun bandotan (Ageratum conyzoides) pada transportasi sistem tertutup ikan komet (Carassius auratus) yang ditransportasikan selama 48 jam terhadap kualitas air, kelulushidupan, respons stres, pertumbuhan ikan pasca transportasi dan analisis keuntungan penggunaan ekstrak daun bandotan. Penelitian menggunakan rancangan acak lengkap (RAL) dengan 3 perlakuan dan 3 ulangan. Perlakuan terdiri dari kontrol dengan kode K0, penambahan esktrak sebanyak 0,25 ml L-1 dengan kode K025, penambahan ekstrak sebanyak 0,5 ml L-1 dengan kode K050. Penambahan ekstrak dengan dosis 0,25 ml L-1 mempunyai TKH sebesar 100% dibanding tanpa penambahan ekstrak dan memiliki nilai keuntungan paling tinggi., The transportation of live fish in aquaculture activities is crucial and deserves attention due to its close connection with the post-transportation stress levels of fish, resulting in increased maintenance costs. This study aims to analyze the effect of adding bandotan leaf extract (Ageratum conyzoides) to the transportation system of comet goldfish (Carassius auratus) transported for 48 hours on water quality, survival rate, stres response, post-transportation fish growth, and the analysis of the benefits of using bandotan leaf extract. The study used a completely randomized design (CRD) with 3 treatments and 3 replications. Treatment consisted of control with code K0, addition of 0.25 ml L-1 extract with code K0.25, addition of 0.5 ml L-1 extract with code K0.50. The addition of the extract at a dose of 0.25 ml L-1 has a TKH of 100% compared to without the addition of the extract and has the highest profit value.

Judul: Addition of Sweet Potato Leaf Extract (Ipomoea batatas) to Tilapia Fish Seed Transportation (Oreochromis niloticus) with a Closed System
Abstrak: Sistem transportasi merupakan hal yang penting dalam proses distribusi ikan karena berpengaruh dengan tingkat stres ikan selama transportasi dan pascatransportasi, kandungan ekstrak pada daun ubi jalar seperti polifenol yang bersifat sebagai pemberi efek relaksasi dan halusinasi selama proses transportasi. Penelitian ini bertujuan untuk menganalisis pengaruh penambahan ekstrak daun ubi jalar (Ipomoea batatas) pada transportasi benih ikan nila (Oreochromis niloticus) dengan sistem tertutup selama 24 jam terhadap kualitas air, glukosa darah, tingkat kelangsungan hidup, dan pertumbuhan pascatransportasi. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan tiga perlakuan dan tiga ulangan. Perlakuan terdiri dari perlakuan kontrol (K), penambahan ekstrak sebanyak 0,25% (A1), penambahan ekstrak sebanyak 0,5% (A2). Penambahan ekstrak dengan dosis 0,25% meningkatkan nilai tingkat kelangsungan hidup sebesar 92% dibandingkan perlakuan lainnya., The transportation system is important in the fish distribution process because it affects the stress level of fish during and after transportation, the extract content in sweet potato leaves such as polyphenols that act as relaxants and hallucinogenic effects during the transportation process. This study aims to analyze the effect of adding sweet potato leaf extract (Ipomoea batatas) to the transportation of tilapia seeds (Oreochromis niloticus) with a closed system for 24 hours on water quality, blood glucose, survival, and post-transportation growth. This study used a completely randomized design (CRD) with three treatments and three replications. The treatments consisted of treatment control (K), addition of 0.25% extract (A1), addition of 0.5% extract (A2). The addition of extract with a dose of 0.25% increased survival by 92% compared to other treatments.

Judul: The Exploration of Discrete Logarithm over Finite Field GF(3m)
Abstrak: The security of many public~key algorithms is based on the problem of finding discrete logarithms. The generalized discrete logarithm problem is the following: given a finite cyclic group G of order n, a generator a of G, and an element fl E G, find the integer x, 0 ~ x ~ n - 1, such that 0: = fl. Algorithm for discrete logarithm problem focused on Menezes et al. (1997) that consist of exhaustive search algorithm, the baby-step giant-step algorithm, Pollard's rho algorithm, Pohlig-Hellman algorithm, and index-calculus algorithm. These algorithms are explorated to be used in discrete logarithm problem over finite field GF(3m ). The exploration also produces some algorithms, i.e. naif negative algorithm, baby-step mother-step algorithm, baby-step mother free-step algorithm, and baby-step free-step algorithm. All algorithms implemented using Maple 11. The Pohlig-Hellman and baby-step giant-step algorithms are efficient enough to be used in discrete logarithm problem over finite field GF(3m ) for m < 20.
