Pengembangan Sari Nanas Tinggi Aktivitas Antioksidan Menggunakan Pendekatan Half Factorial Design
Get PDFNanas (Ananas comosus L.) subang memiliki potensi untuk dibuat menjadi pangan fungsional sari nanas yang memiliki aktivitas antioksidan. Untuk menghasilkan produk yang tahan lama dan memiliki aktivitas antioksidan, maka sari nanas dibuat dengan melewati empat faktor perlakuan yaitu pemilihan bahan, penambahan gula, blansing, dan pemasakan dengan masing–masing terdiri dari dua variabel yaitu positif dan negatif. Penelitian ini bertujuan untuk menganalisa pengaruh empat faktor perlakuan tersebut terhadap aktivitas antioksidan dari sari nanas. Pembuatan sari nanas didesain melalui pendekatan half design experiment. Uji aktivitas antioksidan dilakukan dengan metode peredaman radikal bebas 2,2-diphenyl-1-picrylhydrazyl (DPPH). Hasil penelitian menunjukkan bahwa seluruh sampel yang disimpan pada suhu kamar mengalami fermentasi kurang dari 7 hari pengujian, sedangkan seluruh sampel yang disimpan pada suhu dingin lebih tahan lama sehingga dilanjutkan pada pengujian selanjutnya. Diagram pareto menunjukkan pemilihan bahan, konsentrasi gula, dan durasi waktu blansing secara nyata memberikan pengaruh terhadap peningkatan aktivitas antioksidan dari sari nanas. Namun demikian, durasi waktu pemasakan masih perlu dianalisis lebih lanjut

HKSA secara In-Silico Senyawa 1-Benzil-3- Benzoilurea dan Analognya sebagai Penghambat Reseptor Bruton Tyrosine Kinase (BTK)
Get PDFAbstract—In this study, a new anticancer drug design for non-Hodgkin’s lymphoma was carried out, with a molecular docking approach from the compound 1-benzyl-3-benzoylurea parent and its analog as an anticancer compound. The purpose of the study was to obtain the best quantitative structure-activity relationship (QSAR). The in-silico activity test was carried out on the new 1-benzyl-3-benzoilurea and its analog compound against the Bruton Tyrosine Kinase receptor (BTK) PDB code (5FBN) by using the Molegro Virtual Docker 5.5 program and producing a RS (Rerank Score) value for the test compound and Acalabrutinib was used as a comparison. This study also conducted bioavailability by predicting the value of F (intestinal human absorption) in the pkCSM program and toxicity studies by predicting LD50 values using the Protox II program. Correlation and regression were performed using the RS, F, and LD50 values that we obtained on the physicochemical properties of the test compound using the IBM SPSS version 24 program. The best equation is obtained as follows: (1) F = 0.851 Es Taft - 6.116 σ - 1.969 π² + 3.620 π + 90.809; (2) RS = 4.376 Es Taft - 88.802; (3) LD50 = 672.518 CMR - 669.385 ClogP - 813.806. From the results of the best equation is obtained that the activity is influenced by the parameters of steric physicochemical properties (Es Taft).

Studi Toksisitas Akut dari Herbisida Senyawa Aktif Parakuat, Glifosat, dan Metsulfuron pada Cacing Tanah (Eisenia fetida)
Get PDFAbstract—Earthworm plays important role in the terrestrial ecosystem as decomposer and sensitive to environmental changes. Herbicide application as an effort to improve farm productivity may produce some effects on earthworms. The objective of this study was to find the toxicity level of paraquat, glyphosate, and metsulfuron, the three most common active ingredients of herbicide, on earthworm, Eisenia fetida. Three hundred adult earthworms, weighed between 300 to 600 mg, were divided evenly into one control group and four treatment groups for each herbicide. A dose of 0, 500, 1000, 2000, 4000 mg/kg for paraquat; 0, 2500, 5000, 10000, 20000 mg/kg for glyphosate; and 0, 750, 1500, 3000, 6000 mg/kg for metsulfuron was sprayed and mixed evenly on medium of earthworms medium. Each treatment was replicated 4 times. The mortality rate was recorded daily for 14 days and used as data to calculated LC50 of each herbicide. LC50 of paraquat, glyphosate, and metsulfuron was 951.93 ± 115.63 mg/kg, 5456.36 ± 514.62 mg/kg, and 2599.96 ± 211.85 mg/kg, respectively. On the other hand, the weight of earthworm has a negative correlation with the dose of herbicide applied to the medium. Based on this study, paraquat was the most toxic herbicide followed by metsulfuron and glyphosate.

Abstrak— Cacing tanah memiliki peran yang penting di ekosistem terestrial sebagai dekomposer dan peka terhadap pengaruh lingkungan. Penggunaan herbisida sebagai sarana peningkatan produksi lahan pertanian kemungkinan memiliki dampak terhadap cacing tanah. Penelitian ini bertujuan untuk menentukan LC50 (15 hari) dari herbisida kelompok parakuat, glifosat, dan metsulfuron pada Eisenia fetida dan pengaruhnya terhadap perubahan berat cacing tanah. Pada penelitian ini digunakan tiga ratus cacing tanah dewasa (sudah terbentuk klitelum) dengan berat masing-masing antara 300-600 mg yang dibagi menjadi satu kelompok kontrol dan 4 kelompok perlakuan untuk tiap kelompok jenis herbisida. Herbisida didedahkan ke dalam media tempat tinggal cacing sebanyak 0, 500, 1000, 2000, 4000 mg/kg untuk parakuat; 0, 2500, 5000, 10000, 20000 mg/kg untuk glifosat; dan 0, 750, 1500, 3000, 6000 mg/kg untuk metsulfuron. Masing-masing perlakuan dilakukan empat kali pengulangan. Jumlah cacing tanah yang mati dicatat selama 14 hari pengamatan dan pada akhir pengamatan ditentukan nilai LC50 dari setiap herbisida. Nilai LC50 yang didapat pada kelompok parakuat, glifosat, dan metsulfuron adalah sebesar 951.93 ± 115.63 mg/kg, 5456.36 ± 514.62 mg/kg, dan 2599.96 ± 211.85 mg/kg. Berat cacing tanah didapatkan menurun seiringan dengan meningkatnya konsentrasi herbisida. Dengan demikian, dapat disimpulkan bahwa herbisida dari kelompok senyawa aktif parakuat memiliki toksisitas paling tinggi, disusul oleh herbisida dari kelompok senyawa aktif metsulfuron dan glifosat.

Perancangan Inovasi Drone Pencegah Penyebaran Covid-19 Menggunakan Integrasi Model Kano dan HOQ
Get PDFAbstract—COVID-19 be a concern in all countries because of its rapid spread through droplets or airborne. The COVID-19 Task Force recorded that 1.4 million Indonesians were exposed to the virus. The government has established health protocols, one of which is social distancing. However, as time goes by, people's awareness of the dangers of COVID 19 is decreasing. Many people violate health protocols and crowd in various places. Based on these problems, a disease transmission prevention tool is designed to reducing the spread of the virus. The method used in this research is Kano Model. From the results of the voice of customer and Kano Model analysis, it was found that the drone that consumers want is have a disinfectant in the form of 360⁰ UVC rays, sound transmission in the form of a mic along with speakers, both of which are included in the attractive category, while the one-dimensional category is a temperature gauge in the form of infrared rays to help detect the symptoms of the COVID-19 virus. The presence of PATRON is expected to help the COVID-19 Task Force in an effort to prevent the transmission of the COVID-19 virus.

Abstrak—Virus COVID 19 menjadi perhatian di berbagai negara dikarenakan penyebaranya yang cepat melalui droplet atau airborne. Berdasarkan data SATGAS COVID 19 tercatat sejumlah 1,4 juta penduduk indonesia terpapar virus. Pemerintah menetapkan berbagai protokol kesehatan untuk mengurangi risiko penyebaran virus, salah satunya yaitu menjaga jarak. Namun, seiring berjalannya waktu kesadaran penduduk akan bahaya COVID 19 semakin berkurang. Banyak masyarakat yang melanggar protokol kesehatan dan berkerumun di berbagai tempat. Sebagai langkah mengurangi jumlah kerumunan, dibutuhkan sebuah alat untuk membubarkan kerumunan dengan tujuan mengurangi penyebaran virus. Berdasarkan permasalahan tersebut, maka dirancang disease transmission prevention tool. Metode yang digunakan dalam perancangan desain alat adalah Model Kano. Dari hasil voice of costumer dan analisis Model Kano, didapatkan hasil bahwa drone yang dihendaki oleh konsumen yaitu memiliki disinfektan berupa sinar UVC 360⁰, transmisi suara berupa mic beserta speaker, kedua hal tersebut termasuk kedalam kategori attractive, sedangkan kategori one dimensional yaitu pengukur suhu berupa sinar infrared untuk membantu mendeteksi gejala virus COVID-19. Kehadiran PATRON diharapkan dapat membantu membantu SATGAS COVID-19 dalam upaya pencegahan penularan virus COVID-19.
