A group of viruses that can cause disease in humans are coronavirus disease (Covid-19). Several types of COVID-19 are capable of causing infections in the human respiratory tract through coughing and colds such as SARS and MERS. The spread of Covid-19 has become so widespread that the WHO has declared it a world pandemic. The increase in the number of sufferers can be caused by a lack of public awareness of healthy living behavior. This training is carried out so that the people of the Kuanheum village can know and be able to prevent the spread of Covid-19. This activity uses community education methods in the form of socialization and training to the community. The activity was carried out actively and enthusiastically, attended by 29 community representatives, especially young people, housewives and village officials. Training on making disinfectant liquid using household materials that are easy to obtain and inexpensive. Activities are carried out in 4 stages: 1) site survey; 2) the implementation was carried out at GMIT Horeb, Kuaheum; 3) evaluation by the PkM team. Based on the evaluation carried out, it can be seen that of the 29 respondents who gave feedback on activities for understanding the manufacture of disinfectant liquid before being given training materials (P1) were in the sufficient (28.6%) and very good (61.9%). This activity has a positive impact on the understanding and skills of the Horeb Kuanheum congregation about preventing the spread of Covid-19. Keywords: Disinfectant, Practice, Respondent, Socialization, Virus.

Sandalwood (Santalum album L.) which grows in East Nusa Tenggara is an endemic plant known as hau meni. Sandalwood is used as a base for carving and perfume containing essential oils that have a distinctive aroma. The superiority that is owned causes the selling price is very expensive. This causes exploitation which results in a diminishing number of Sandalwood trees. Efforts to replant have been carried out through seedlings and nurseries but the success rate is still low. Efforts through invitro are expected to help conserve this plant. To determine the effect of giving Liquid Organic Fertilizer (LOF) on the growth of Sandalwood and the best concentration in promote germination. The study was conducted by adding different types of LOF with concentration variation. The addition of Nasa with a concentration of 2 mL which is the optimal concentration in promote the germination with the response at 14 Days After Planting (DAP) on Murashige and Skoog (MS) medium while on the addition of lontar the concentration of 2 mL shows the response of the appearance of plumula. The addition of base type LOF on MS medium affected 82% germination percentage while lontar type LOF stimulated vegetative growth of Sandalwood plants.

Application of activated charcoal in agriculture will give advantage for plant growth because will enrich nutrients, mantain soil properties, enhance root development and increase microorganism propagation and activities that would support the plant growth. The objective of this research is to examine the effect of Saboak shell (Borassus flabellifer L.) activated charcoal addition into culture medium on growth of Gude plants (Cajanus cajan L.). Saboak shell (Borassus flabellifer L.) was carbonised in drum kiln to produce charcoal, then activated charcoal using H2SO4 for 180 minutes at 110 0C. The activated charcoal produced is then applied as a component of growing media of Gude plants (Cajanus cajan L) with levels of 5, 10 and 15% of the media weight. The results showed that addition of activated charcoal to the growth media could significantly increase the growth rate, growth rate and root length when compared to the control. The best addition of activated charcoal for Gude growth media is 10%, which with this level can increase growth height of 27.33 cm growth rate of 0.79 cm / day and root length of 15.13 cm for 30 days.

Telah dilakukan penelitian tentang pemanfaatan biochar dan arang aktif dari sumber biomassa tempurung lontar dan seresah (biomassa yang berpotensi sebagai limbah organik). Biomassa yang dihasilkan dimanfaatkan untuk pemurnian minyak jelantah di Kota Kupang. Tujuan penelitian ini adalah memanfaatkan biochar dan arang aktif dari 2 jenis biomaterial untuk pemurnian minyak jelantah pada variasi waktu 20 jam, 22 jam, dan 24 jam. Ukuran partikel biomaterial yang digunakan adalah 65 mesh. Hasil penelitian menunjukkan bahwa biomaterial yang digunakan berperan sebagai biosorben yang ramah lingkungan (eco friendly). Uji kualitas meliputi bilangan peroksida, kadar asam lemak bebas, bilangan asam, dan pH dilakukan sebelum dan setelah pemurnian. Hasil uji sebelum pemurnian untuk minyak jelantah menunjukkan sampel 2 (M.1x.P.GO) layak digunakan dengan nilai kualitas secara berturut-turut meliputi bilangan peroksida adalah 13.94 meq/kg dan 19.268 meq/kg; asam lemak bebas adalah 0.128% dan 0.519%; bilangan asam adalah 0.200 mg KOH/g dan 0.811 mg KOH/g; pH adalah 4. Uji kualitas minyak setelah dimurnikan menggunakan ke-4 jenis biosorben yaitu arang tempurung lontar amorf, arang seresah amorf, arang aktif tempurung lontar, dan arang aktif seresah menunjukkan hasil optimum terjadi pada jam ke-22 dan ke-24 untuk sampel 2 (M.1x.P.GO). Secara berturut-turut nilainya adalah bilangan peroksida pada biosorben amorf dan arang aktif seresah yaitu 3.987 meq/kg; asam lemak bebas dan angka asam pada arang aktif seresah selama 22 jam secara berturut-turut yaitu 0.364% dan 0.569 mg KOH/g; serta pH pada biosorben arang aktif tempurung lontar selama 24 jam yaitu 5.927. Stabilitas biosorben perlu ditingkatkan agar kualitas minyak setelah dimurnikan bisa dipertahankan.
