ANALISA UNJUK KERJA AUDIO DAN VIDEO STREAMING PADA JARINGAN MPLS VPN BERBASIS IPSec

Saat ini makin banyak masyarakat di Indonesia yang menggunakan aplikasi audio dan video streaming dalam kehidupan sehari-harinya. Dengan adanya videostreaming bisa digunakan untuk berbagai kegiatan seperti pendidikan jarak jauh ataupun sebagai sarana monitoring. Pada jaringan publik mempunyai kelemahan yaitu kurangnya keamanan komunikasinya, untuk mengatasi hal itu maka digunakanlah teknologi VPN (Virtual Private Network) pada jaringan tersebut. VPN memungkinkan terbentuknya sebuah jaringan data privat pada jaringan publik dengan menerapkan autentikasi dan enkripsi sehingga akses terhadap jaringan tersebut hanya dapat dilakukan oleh pihak-pihak tertentu. Pada paper ini menganalisa Qos dari jaringan MPLS VPN, meliputi parameter Qos yaitu delay, jitter, packet loss dan troughput. Dengan analisa ini diharapkan para pengguna teknologi audio dan video streaming mengetahui sejauh mana performansi dari aplikasi tersebut melalui jaringan MPLS VPN

RANCANG BANGUN DAN ANALISA QoS AUDIO DAN VIDEO STREAMING PADA JARINGAN MPLS VPN

Today and more people in Indonesia to use audio and video streaming applications in daily life. With the streaming video we can use it for various activities such as distance education or as a means of monitoring. In the public network has security weaknesses are lack of communication, to overcome this, the technology is used VPN (Virtual Private Network) on the network. VPN allows the formation of a network of private data on public networks by applying authentication and encryption so that access to these networks can only be done by certain parties. Layers of additional security such as IPSec can be applied to data security, if necessary. Such methods, however, without any IPSec, VPN with MPLS can be used well. In this thesis analyzes the QoS of MPLS VPN network, the QoS parameters include delay, jitter, packet loss and throughput. Quality of Service (QoS) of video streaming is absolutely taken to ensure that users feel satisfied when using it. With this analysis are expected video streaming technology users through a VPN MPLS network is to know the extent to which the performance of videostreaming via MPLS VPN networ

Pertumbuhan, Produksi Biomassa, dan Kandungan Glikosida Steviol pada Lima Klon Stevia Introduksi di Bogor, Indonesia

Stevia rebaudiana Bertoni, a sweetener plant, has been cultivated in Indonesia since the early 1980s, but the yield is lower than in other countries. Five selected introduced stevia clones were planted at Megamendung, Bogor, Indonesia (6°39’ S, 106°56’ E, 800 m above sea level) on December 2014 until November 2015 to evaluate their growth and biomass yield. The growth and yield were observed from 6 to 12 months after planting. In addition, stevioside, rebaudioside A (reb A), and total steviol glycoside (TSG) contents of leaves were measured using high performance liquid chromatography (HPLC). At six months after planting, stem diameter was 8-11 mm, plant canopy diameter was 23-30 cm, plant height was 24-35 cm, and plant mortality was less than 5% except for clone BU at 30.7% due to Sclerotium attack. The plants flowered at different times, therefore had different harvest durations, from 4 weeks (clone BM) to 8 weeks (clone BP). The highest leaf yield was clone BM (6.04 ton ha-1 per year), followed by BX (4.91 ton ha-1 per year), and BP (4.38 ton ha-1 per year). From the five clones tested, clone BM was the best for leaf, TSG, and stevioside yields; whereas clone BS and BP were the best for reb A yield. Keywords: rebaudioside A, Stevia rebaudiana, stevioside, total steviol glycosid

ETNOBOTANI DAN AKTVITAS ANTIOKSIDAN PADA BIJI DAN TANGKAI BUAH HANJELI (Coix lacryma-jobi L.)

Etnobotani dan uji aktivitas antioksidan pada tumbuhan Hanjeli (Coix lacryma-jobi L.) terutama yang berasal dari Jawa Barat belum diteliti. Tujuan dari penelitian adalah untuk mengungkap sistem pengolahan, pemanfataan tumbuhan Hanjeli oleh masyarakat di Kampung Cekdam dan mengungkap aktivitas antioksidan pada biji dan tangkai buah Hanjeli liar maupun budidaya. Hanjeli liar diambil dari Dusun Ciawi, Kabupaten Sumedang dan Hanjeli budidaya diambil dari Kampung Cekdam, Kabupaten Sukabumi. Penelitian Etnobotani dilakukan dengan teknik pengambilan sampel purposive sampling. Teknik pengumpulan data dilakukan dengan wawancara semi terstuktur. Data kuantitatif diperoleh dengan menggunakan metode pendekatan nilai penting atau Use Value (UVs). Biji dan tangkai buah Hanjeli diekstrak menggunakan pelarut etanol 96% dengan metode maserasi. Pengujian aktivitas antioksidan dari masing-masing ekstrak dilakukan dengan metode pengukuran penangkapan radikal oleh 1,1-difenil-2-pikrihidrazil (DPPH). Hanjeli ditanam secara monokultur atau tumpang sari. Pengolahan dimulai dari pemilihan bibit, penanaman dan pemeliharaan. Tanaman tersebut dipanen pada usia 5-7 bulan dan dikeringkan dengan bantuan cahaya matahari. Hanjeli yang dibudidayakan di Kampung Cekdam dimanfaatkan sebagai bahan makanan, obat, kayu bakar, pakan ternak dan aksesoris. Nilai UVs tertinggi yaitu Hanjeli ketan (1,70) hal ini berkaitan dengan banyaknya pemanfaatannya oleh masyarakat. Ekstrak biji Hanjeli liar maupun budidaya memiliki aktivitas antioksidan yang sangat lemah karena memiliki nilai IC50 lebih dari 200 ppm. Ekstrak tangkai buah Hanjeli memiliki aktivitas antioksidan yang kuat dengan nilai IC50 berada di antara 50-100 ppm. Aktivitas antioksidan ekstrak tangkai buah jauh lebih tinggi dibanding biji. Hanjeli budidaya memiliki aktivitas lebih tinggi dibanding Hanjeli liar. Ethnobotany and antioxidant activities tests of job’s tears (Coix lacryma-jobi L.) especially from West Java have not been researched. The purpose of the research is to reveal the processing system, utilization of job’s tears by the community in Cekdam Village and to reveal the antioxidant activities of wild and cultivation seeds and fruit stalks of job’s tears. Wild job’s tears is taken from Ciawi, Sumedang and cultivation job’s tears is taken from Cekdam, Sukabumi. Ethnobotany research was conducted by using purposive sampling technique. Data collection techniques were carried out with semi-structured interviews. Quantitative data were obtained using the Use Value (UVs) approach. Seeds and stalks of job’s tears were extracted using 96% ethanol solvent by maceration method. The antioxidant activities test of each extract was carried out by measuring the radical scavenging method by 1,1-diphenyl-2-picrihydrazyl (DPPH). Job’s tears is planted monoculture or intercropping. Processing start from seed selection, planting and maintenance. These plants are harvested at the age of 5-7 months and dried with the help of sunlight. Job’s tears cultivated in Cekdam is used as food, medicine, firewood, animal feed and accessories. The highest UVs value is sticky rice of job’s tears (1.70) this is related to the many uses by the community. Both wild and cultivated job’s tears of seed extracts have very weak antioxidant activities because they have an IC50 value of more than 200 ppm. Fruit stalk extract of job’s tears has strong antioxidant activities with an IC50 value between 50-100 ppm. The antioxidant activities of the fruit stalk extract was higher than the seeds. Cultivated job’s tears has higher activities than wild job’s tears
