“…This can be due to PLB mutations which occur randomly and form pyrimidine dimers which have an impact on increasing their multiplicative ability although not as well as the wild type. Radiation with UV-C light (λ=100-280 nm) causes chromosome damage due to the wavelength energy absorbed by purines and pyrimidines which results in transitions between guanine-cytosine and adenine-thymine nitrogen base pairs (Yulianto et al, 2019).…”

Phalaenopsis sp. is the most-produced orchid species in Indonesia. Compared to conventional breeding, mutation induction by using mutagens, such as Ultraviolet Light-C (λ = 254 nm) (UV254) and Ethyl Methane Sulfonate (EMS), could probably result in new superior orchid variants. This research aims to get some mutants with phenotypes that have visual differences in the Phalaenopsis spp. hybrids wild type. There were 4 durations of UV254 irradiation: 5’ on, 85’ off; 10’ on, 80’ off (1 day and 7 days for each treatment); 4 concentrations of EMS used in this research: 0.05%; 0.06%; 0.07%; 0.08% for 6 hours of immersion; selected UV254 irradiation (5’ on, 85’ off (7 days)) combined with these concentrations. UV254 irradiation treatment (5’ on, 85’ off (1 day and 7 days); 10’ on, 80’ off (7 days)) resulted in some mutants with leaf phenotypes that were visually different from the wild type; 0.05% EMS treatment resulted in PLBs mutant with a visually larger size than the wild type; 0.08% EMS treatment and combination treatments (for EMS 0.05% and 0.08% for each treatment) resulted in non-growing albino PLBs. Hence, mutation induction using UV254 and EMS in this research produced several most likely mutants having visual differences that may be more desirable than the wild type.

Pengolahan kopi kering sangat berpengaruh pada kualitas kopi yang dihasilkan. Kendala yang dihadapi pada pengolahan kopi adalah waktu dan energi yang dibutuhkan masih terlalu besar. Selain itu hasil dari kapasitas pengupasan kulit kopi kering kurang baik karena terlalu lambat. Pengeringan merupakan hal yang sangat penting pada pengolahan kopi, tanpa pengeringan yang baik kualitas biji kopi tidak akan maksimal. Berdasarkan uraian masalah penerapan teknologi Smart Coffee Dry-Huller Machine bertujuan untuk mengupas dan mengeringkan biji kopi secara otomatis yang ramah lingkungan dengan biaya terjangkau bagi petani kopi serta biji kopi yang higienis. Metode yang digunakan dalam perancangan alat tersebut yaitu dengan melalui tahap praproduksi, tahap produksi dan tahap pasca produksi. Potensi energi yang digunakan pada mesin pengupas sebesar 2,04watt saat mode standby, 47watt saat mode low, 52watt saat mode medium, dan 55watt saat mode high, sedangkan potensi energi pada mesin pengering sebesar 357watt dan dapat menurunkan kadar air sebesar 10%/jam dengan suhu maksimal 53,9°C.

“…Radiasi sinar UV yang dibutuhkan untuk membunuh bakteri berada dalam rentang panjang gelombang sinar UVC, yaitu 220-290 nm. Pada rentang tersebut, nilai yang paling efektif adalah pada panjang gelombang 254 nm (Yulianto et al, 2019). Absorpsi sinar UV tersebut dapat menyebabkan mutasi sel (Yulianto et al, 2019) serta kematian agen biologis seperti mikroba dan virus (Muvianto & Yuniarto, 2020).…”

The number of people confirmed positive for Coronavirus Disease 2019 (COVID-19) in Indonesia reached 605,243 people as of December 11, 2020, of which 18,511 people died. COVID-19 is caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) which can spread rapidly through droplets and is viable under certain conditions. On the other hand, the Ministry of Education and Culture of the Republic of Indonesia plans to allow face-to-face lectures starting in January 2021. Of course this requires strict health protocols and facilities that support learning activities without increasing cases of COVID-19 transmission. Therefore, in this paper an innovation is designed in the form of a smart classroom consisting of a sterilization system based on ultraviolet C (UVC) light with a wavelength of 254 nm. Smart classrooms are also equipped with a security system in the form of automatic locks, contactless sensors for opening and closing doors, automatic lighting, and a real-time Internet of Things (IoT) based monitoring system. In this paper, a system simulation is carried out using Tinkercad and the Thingspeak web server. The sterilization process is designed to be carried out for 30 minutes with a UVC dose of 220 J / m2. For a classroom with an area of 64.17 m2, a dosage of 14,117.4 J is needed, so it takes 2 Philips UVC TMS030 1xTUV T8 18W HFP which has an irradiation of 0.09 W / m2.
