Pendampingan Pelaporan SPT Tahunan Berbasis E-filing Bagi Pedagang Kelontong di tengah Wabah Covid-19
Government appeals to stay at home and restrictions on the delivery of public services do make people less comfortable in receiving public services, but this is a policy currently taken by the government is an effort to limit or stop the spread of Corona Virus. based on the instructions given, DJP (Direktorat Jenderal Pajak) then stop reporting directly and lead to the use of e-filing and extend the tax reporting period that should end on 31 March 2020 to 30 April 2020. Termination is what later became a problem experienced by taxpayers, especially the grocery traders in Gerung Market, Gerung District, West Lombok Regency, where the average trader was very unfamiliar with the use of electronics, especially the use of computers and the internet. By coordinating with an account representative, the servant provides assistance to traders who wish to report their annual tax return online while still paying attention to social distancing or maintaining a safe distance from participants. because of the adaptations made so that not all registered participants can be accompanied, namely only 50% of participants who successfully report online, 20% of participants are reported manually and the rest are still waiting for further policies
Pollen Viability and Microspore Culture in Three Broccoli Cultivars (Brassica oleracea L. var. italica Plenck)
Broccoli is a high value vegetable crop in Indonesia, however production is low due to limited number of suitable cultivars, so, breeding hybrid broccoli for warm climate is important. The first step in hybridization is providing homozygote parent plants which can be done efficiently via microspore culture. The objectives of this study were to determine 1) bud size that produce uninucleate microspore stage appropriate for culture; 2) pollen viability, 3) microspore development, in three broccoli cultivars (‘BL 10001’, ‘Royal Green’ and ‘Green Magic’). Various bud size (1 – 5 cm) was squashed and observed microscopically to determine bud size containing uninucleate microspore. Pollen viability was determined by IKI staining and pollen germination method. Chromosome number was counted on root tips using squash method with aceto-orcein stain. Various heat treatment schemes were conducted to induce microspreo development. Result showed uninucleate microspore derived from 2-3 mm and 3-4 mm bud length of ‘BL-10001’ and ‘Royal Green’ was responsive for microspore development in culture. Pollen viability varied among cultivars, 78-87% on IKI method and 15-16% on germination test. Microspore culture showed different embryogenesis response; pollen-like structure was produced by ‘BL 10001’
Genetic Diversity and Phylogenetic of Longtail Tuna (Thunnus tonggol) Landed in Pabean Fish Market, Surabaya
Indonesia is the biggest tuna exporter in Southeast Asia. With a high number of tuna catch, it is worried that the catch will decrease tuna population, specifically longtail tuna. To anticipate the decrease, there needs to be a conservation program to protect longtail tunas from scarcity. One method used to protect longtail tuna is by genetic conservation. The aim of this research is to understand the genetic and phylogenetic variety of the longtail tuna in Pabean Surabaya Fish Market. The polymerase chain reaction was used to amplify segment of the mitochondrial control region gene from members of these sample, used forward primer CRK 5’-AGCTC AGCGC CAGAG CGCCG GTCTT GTAAA-3’ and reverse primer CRE 5’-CCTGA AGTAG GAACC AGATG-3’. Based on the sequencing process, 28 out of 29 samples longtail tuna were analyzed successfully. The results of the 28 sample analysis of longtail tuna based on its genetic variety and phylogenetic tree reconstruction showed a haplotype variety (Hd) score of 1,00000, and nucleotide (π) variety of 0,1939. Genetic variety value showed that longtail tuna has great adaption capabilities toward environmental changes time to time. Phylogenetic tree reconstruction results showed 7 clades with a genetic range of 0,005 – 0,035, which shows that all samples are closely related. The results of this study can be used as basic information in forming regulations on longtail tuna sustainable management and genetic conservation

Optimasi Metode Cryotherapy untuk Mengeliminasi Virus pada Tunas Kentang In Vitro (Optimation of Cryotherapy Method to Eliminate Virus on In Vitro Potato Shoot Tips)
Penggunaan benih kentang generasi awal dan bebas virus merupakan kunci keberhasilan produksi kentang berkualitas. Cryotherapy (perendaman dalam nitrogen cair) merupakan teknik terbaru untuk mengeliminasi virus pada benih kentang. Salah satu kendala dalam penerapan teknologi cryotherapy ialah tingkat daya hidup eksplan yang masih rendah. Penelitian ini bertujuan untuk mengetahui efektifitas teknik enkapsulasi-dehidrasi untuk mendapatkan tunas yang sehat setelah perendaman dalam nitrogen cair. Ujung tunas in vitro ukuran 2–3 mm dari empat genotipe kentang di prakultur selama 3 hari secara bertahap pada media MS dengan penambahan gula 0,25 M, 0,5 M, dan 0, 75 M. Kemudian tunas dienkapsulasi, didehidrasi selama 5 jam, lalu direndam dalam nitrogen cair selama 60 menit lalu dihangatkan kembali dalam waterbath selama 3 menit. Tunas dalam kapsul kemudian dikulturkan pada media MS +30 g/l sukrosa + 8 g/l agar + 0,4 mg/l BAP + 1 mg/l GA3 untuk pemulihan, lalu dipelihara di ruang kultur dengan suhu 24oC. Daya hidup ujung tunas diamati pada minggu ke-8 dengan menggunakan kriteria skoring sebagai berikut: (1) pemutihan jaringan dan tidak ada respons pertumbuhan, (2) kalus mencokelat, (3) kalus hijau, (4) tumbuh tunas, dan (5) planlet sehat. Hasil penelitian menunjukkan daya hidup ujung tunas bervariasi antargenotipe. Skor daya hidup berkisar 1–2 (frekuensi 2–10) pada perlakuan nitrogen cair, yang menunjukkan tidak ada respons pertumbuhan tunas, beberapa memperlihatkan pertumbuhan kalus. Tunas pada perlakuan kontrol (tanpa perendaman dalam nitrogen cair) menunjukkan skor daya hidup 5 (frekuensi 1–7), di mana ujung tunas mampu beregenerasi menjadi planlet.KeywordsCryopreservation; Solanum tuberosum; Kultur jaringan tanaman; Eliminasi virusAbstractVirus-free, early generation seed is a key in the production of high quality potatoes. Cryotherapy (exposure to liquid nitrogen) is a new and promising method of virus elimination. One bottleneck in cryotheraphy method is survival of the explants after treatment with liquid nitrogen. This study investigated the effectiveness of enkapsulasi-dehidrasi method to obtain survival explants. Shoot tips were precultured for 3 days in MS media with sucrose addition of 0.25 M, 0.5 M and 0.75 M. Shoot tips were then encapsulate, dehydrate for 5 hours, expose to liquid nitrogen for 60 minutes and rewarm in waterbath for 3 minutes. Beads with shoot tips were then cultured in MS media + 30 g/l sucrose + 8 g/l agar + 0.4 mg/l BAP + 1 mg/l GA3 for recovery, and placed in 24oC culture room. Shoot tip survival was assessed at 8 weeks using the following scoring criteria: (1) tissue bleaching and no growth response, (2) brown callus, (3) green callus, (4) shoot growth, and (5) plantlet establishment. Survival was varied among genotypes. Survival scored between 1–2 (frequency 2–10) on liquid nitrogen treatment, showing shoot tips are mostly has no growth response, only some callus growth. Shoot tips on control treatment (without exposure in liquid nitrogen) shows survival scored 5 (frequency 1–7), i.e. shoot tips able to regenerate into plantlets
