Abstract

Abstract : Acoustical design as part of the audio comfort influences the architectural design strategy of a mosque significantly. As belonging to the speech room criteria, a mosque should meet some acoustic room requirements to deliver the solemnness to the worshipper during the prayer. Concerning this, the study aims to assess the indoor acoustics performance of Baiturrahman Grand Mosque, Banda Aceh. Baiturrahman grand mosque is an important place of worship for Acehnese and becoming a landmark of Banda Aceh City. The mosque which contains a lot of history of Aceh was built in heavy construction, i.e. concrete wall, marble coated floor, and concrete dome ceiling. Due to its significance, the room acoustics of the mosque as the primary design considerations in a speech room type is evaluated. The acoustics parameters estimated are Noise Criteria (NC), Sound Pressure Level (SPL), Reverberation Time (RT), and Rapid Speech Transmission Index (RASTI). The background noise was recorded for delivering the noise criteria and being the primary data carried out in the acoustic simulation. The study utilised CATT-Acoustic v7.2 software for simulating predicting SPL, RT, and RASTI.Abstrak : Desain akustik merupakan bagian dari parameter audio yang mempengaruhi desain arsitektur masjid secara signifikan.

Abstract

Abstract : The rapid development of the internet has an impact on the security of data sent using internet media. One government agency that uses the internet as data transmission includes the KPU. Data transmission becomes very risky especially the data sent is very important and even confidential. In the internet world, there are many threats and ways to change or retrieve data sent via the internet. Indonesia in particular has conducted direct elections but the data that are in the regions which are the results of recapitulation of the elections will be sent via the internet with a system provided by the KPU. Data from the recapitulation of regional elections becomes very important because it can be changed by intruders. Secure the data sent, methods such as cryptographic techniques that can minimize interference from intruders are needed. One algorithm that can be applied as data security is the GOST algorithm. The GOST algorithm is designed to take a balance between data efficiency and security. Cryptographic techniques that use the GOST algorithm are expected to be able to increase the security of sending election results from various threats without reducing the performance of sending data.

Election result data that was conducted during the testing was the Ogan Ilir regional election recap data. Tests that have been carried out using the GOST algorithm using WireShark produce stream files sent over the network are not easily identified because they are converted into random strings, so it takes a long time to analyze them.Abstrak : Perkembangan internet yang sangat cepat mempunyai dampak diantranya keamanan data yang dikirim menggunakan media internet. Salah satu instansi pemerintahan yang menggunakan internet sebagai pengiriman data diantaranya KPU. Pengiriman data menjadi sangat beresiko terlebih data yang dikirimkan sangat penting bahkan bersifat rahasia. Didunia internet terdapat banyak ancaman serta cara dalam mengubah atau mengambil data yang dikirimkan melalui media internet. Indonesia pada khususnya telah melakukan pemilu secara langsung tetapi data-data yang berada pada daerah yang merupakan hasil rekapitulasi dari pemilu akan dikirimkan melalui internet dengan sistem yang telah disediakan oleh KPU. Data hasil rekapitulasi pemilu suatu daerah menjadi sangat penting dikarenakan bisa diubah oleh intruder. Untuk mengamankan data yang dikirimkan diperlukan metode seperti teknik kriptografi yang bisa meminimalisir gangguan dari para intruder. Salah satu algoritma yang bisa diterapkan sebagai keamanan data yaitu algoritma GOST. Algoritma GOST dirancang agar mengambil keseimbangan antara efisiensi dan keamanan data. Teknik kriptografi yang menggunakan algoritma GOST mampu meningkatkan keamanan pengiriman data hasil pemilu dari berbagai ancaman tanpa mengurangi performansi dari pengiriman data. Data hasil pemilu yang dilakukan saat pengujian ialah data rekap pilkada Ogan Ilir. Pengujian yang telah dilakukan menggunakan algoritma GOST menggunakan wireshark menghasilkan stream file yang dikirim melalui jaringan tidak mudah diidentifikasi dikarenakan diubah menjadi string acak sehingga membutuhkan waktu yang lama untuk menganalisanya.

Abstract

Abstract : This study was designed to evaluate the anti-diabetic activity of the ethanol extract of Syzygium cumini leaves in alloxan-induced diabetes mice. The anti-diabetic activity of EDS was investigated in mice (Mus musculus SW.) Alloxan-induced diabetes. The effect of ethanol extract of Syzygium cumini leaves on normal blood glucose levels and oral glucose tolerance tests were studied in normoglycemic mice while the anti-diabetic effect was evaluated in alloxan-induced hyperglycemic mice. Ethanol extract of Syzygium cumini leaves (200 and 400 mg/kg) is given orally for 21 days. Glibenclamide (5 mg/kg, oral for 21 days) is used as a reference standard. Giving ethanol extract of Syzygium leaves causes a significant decrease in blood glucose levels in normoglycemic and hyperglycemic mice and also increases glucose tolerance test. Ethanol extract of Syzygium leaves reduces glycosylated hemoglobin levels, lactate dehydrogenase, and creatinine kinase in alloxan-treated mice. Ethanol extract of Syzygium leaves also improves TBARS oxidative stress parameters, catalase and superoxide dismutase activity and glutathione levels. The ethanol extract of Syzygium cumini leaves shows anti-diabetic activity through increased insulin secretion and this effect can be attributed to the content of flavonoids and phenolic compounds present in the ethanol extract of Syzygium cumini leaves.Abstrak : Penelitian ini dirancang untuk mengevaluasi aktivitas anti-diabetes dari ekstrak etanol daun Syzygium cumini (L) Skeels (EDS) pada mencit diabetes yang diinduksi aloksan. Aktivitas anti-diabetes EDS diselidiki pada mencit (Mus musculus SW.) diabetes yang diinduksi aloksan. Pengaruh ekstrak etanol daun Syzygium cumini (EDS) pada kadar glukosa darah normal dan uji toleransi glukosa oral dipelajari pada mencit normoglikemik sedangkan efek antidiabetik dievaluasi pada mencit hiperglikemik yang diinduksi aloksan. EDS (200 dan 400 mg/kg) diberikan secara oral selama 21 hari. Glibenclamide (5mg/kg, oral selama 21 hari) digunakan sebagai standar referensi. Pemberian EDS menyebabkan penurunan signifikan dalam kadar glukosa darah pada mencit normoglikemik dan hiperglikemik dan juga meningkatkan uji toleransi glukosa. EDS mengurangi kadar hemoglobin glikosilasi, laktat dehidrogenase, dan kreatinin kinase pada mencit yang diberi aloksan. EDS juga memperbaiki parameter stres oksidatif TBARS, aktivitas katalase dan superoksida dismutase dan kadar glutathione. Ekstrak etanol daun Syzygium cumini (EDS) menunjukkan aktivitas antidiabetik melalui peningkatan sekresi insulin dan efek ini dapat dikaitkan dengan kandungan flavonoid dan senyawa fenolik yang ada dalam ekstrak daun.

Abstract

Abstract : This study aims to determine the antidiabetic activity and toxicity of the acetone extract of Tristaniopsis merguensis Griff leaf. The antidiabetic test was the α-glucosidase inhibition method, while the toxicity test used the Brine Shrimp Lethality Test (BSLT) method. The acetone extract possessed antidiabetic activity with an IC50 value of 8.83 ± 0.31 (μg/mL). This value is not much different from the positive control of quercetin which has an IC50 value of 6.04 ± 0.14 (μg/mL). The characteristics of the FT-IR spectrum of acetone extract showed that Tristaniopsis merguensis leaf has the groups Ar-OH (phenolic), -OH (hydroxyl), C=O (ketone) and C=C (aromatic). Based on the toxicity test, the Tristaniopsis merguensis leaf acetone extract has an LC50 value of 959.25 ppm which means that the acetone extract is toxic. Therefore, the acetone extract of Tristaniopsis merguensis might be the potential agent of antidiabetic.Abstrak : Penelitian ini bertujuan untuk mengetahui aktivitas antidiabetes dan toksisitas dari ekstrak aseton daun Tristaniopsis merguensis Griff. Uji aktivitas antidiabetes ditentukan berdasarkan metode inhibisi enzim α-glucosidase, sedangkan toksisitas ditentukan berdasarkan metode Brine Shrimp Lethality Test (BSLT). Ekstrak aseton memiliki aktivitas antidiabetes dengan nilai IC50 8,83 ± 0,31 (μg/mL). Nilai ini tidak jauh berbeda dengan kontrol positif quersetin yang memiliki nilai IC50 6,04 ± 0,14 (μg/mL). Karakteristik spektrum FT-IR ekstrak aseton menunjukkan bahwa daun Tristaniopsis merguensis memiliki gugus fungsi Ar-OH (fenolik), -OH (hidroksil), C=O (keton) dan C=C (aromatik). Berdasarkan uji toksisitas, ekstrak aseton daun Tristaniopsis merguensis memiliki nilai LC50 sebesar 959,25 ppm yang berarti bahwa ekstrak aseton bersifat toksik. Oleh karena itu, ekstrak aseton dari Tristaniopsis merguensis berpotensi untuk dijadikan agen antidiabetes.
