Abstract

Pandemi Covid-19 yang disebabkan oleh virus Corona telah menjadi permasalahan global, tidak terkecuali di Pekanbaru. Hampir seluruh lokasi di Pekanbaru telah terdampak akibat adanya pandemi Covid-19, salah satunya di Kelurahan Sumahilang, Kecamatan Pekanbaru Kota, Kota Pekanbaru. Untuk mengatasi masalah Covid-19, pemerintah menghimbau masyarakat untuk rajin mencuci tangan dengan sabun. Namun terkadang jika kita bepergian, tidak di semua tempat dan ruangan terdapat air dan sabun, maka hand sanitizer atau cairan antiseptik bisa menjadi alternatif untuk mencuci tangan yang bisa diandalkan. Alkohol sebagai komponen utama hand sanitizer, berfungsi sebagai antiseptik pada permukaan kulit. Alkohol pada pemakaian berulang menyebabkan kekeringan dan iritasi pada kulit. Agar penggunaan alkohol efektif tanpa menimbulkan dampak bagi penggunanya, maka perlu dilakukan inovasi produk antiseptik handsanitizer dengan menggunakan ekstrak tanaman yang mengandung sifat antibakteri. Ekstrak daun sirih dan jeruk nipis dapat memberikan solusi akibat yang ditimbulkan dari hand sanitizer yang menggunakan alkohol. Kegiatan Pelatihan Pembuatan Handsanitizer Alami di Kelurahan Sumahilang dilakukan pada hari Rabu 18 Agustus 2021. Kegiatan ini diikuti 20 peserta yang berasal dari ibu-ibu Posyandu dan PKK Kelurahan Sumahilang. Hasil kegiatan menunjukkan pengetahuan peserta pelatihan mengenai pembuatan hand sanitizer alami meningkat dari 20% menjadi 85% Kata kunci: Covid-19, hand sanitizer alami, jeruk nipis, kelurahan Sumahilang, sirih

Abstract

This study aims to observe the response of nyamplung seedling to various of flooding levels, using a randomized block design with a single factor of five inundation treatments (control, 0 cm or equal the solil surface, 4 cm, 8 cm, 12 cm). Flooding treatment was carried out for 30 days. The observed parameters were growth rate, morphological adaptation, and injury index. Data were analyzed using ANOVA and Duncan Multi Range Taste (DMRT) in the level of 5%.  The results showed that flooding treatment reduce the growth of nyamplung seedling (fresh weight, height, stem diameter, number of leaves, leaf area, and fesh root weight). Seedling of nyamplung able to survive on equal ground flooding level and 4 cm above the soil surface, classified as moderately tolerant plants. Seedlings were not able to survive in the flooding level of 8 cm and 12 cm, classified as sensitive plants. Morphological adaptations such as lenticels formed by 20% on equal ground surface flooding level and 60%  on the flooding level of 4 cm.

Abstract

Nyamplung (Calophyllum inophyllum L.) is a plant that has many functions, almost all parts of the plant can be used and have high economical and ecological functions.The purpose of this study were to test the growth ability of nyamplung at various periods of flooding and observe the morphological adaptations due to this treatments.This research was carried out for 30 days using a randomized block design (RBD) with a single factor, i.e. period of flooding which consisted of 4 treatments as follow P0: control (no flooding), P1 5 days of flooding periods, P2 10 days of flooding periods, and P3 continuous floding. The flood height from the soil was 2 cm. The results of this study indicated that the flooding periods did not significantly affect the plant fresh weight, the plant height as well as the number of leaves.The flooding periods significantly affected the percentage of root growth and root fresh weight. The morphological adaptation of Nyamplung in the period of flooding was by forming lenticels.While the seedling on continuously flooding treatment also formed adventitious roots. The 4 month nyamplung seedling could grow at all of the flooding periods with injury index at 5, 10 day flooding periods and continuously flooding period were 0, 0.09 and 0.58, respectively.

Abstract

Padang island is one of the islands that has the high Sago germplasm (Metroxylon sagu) in Kepulauan Meranti, Riau Province. This region has abundant sago bark waste called sago uyung but it has not been used properly. Sago uyung potentially produce a strong and termite resistant wood that can be used as handcraft raw material. This study aimed to analyze the effectiveness of wood soaking in three water types to the strength of uyung spined-sago of Padang island based on fiber characters. The uyungs of spined-sago were collected from three different habitats of sago, i.e. peat habitat, transition zone of peat and clay habitat as well as clay habitat, and treated in three water types, i.e. peat, sea and fresh water. The measurement and observation of fiber characters used a maseration method. This result showed that based on the treatments, uyung that soaked on the sea water gave the best result due to the longest and widest fiber. Moreover, based on the types of habitat, uyung from the transition zone of peat and clay habitat had the longest and widest fiber. The interaction of uyung from the transition zone of peat and clay habitat with sea water soaking was more effective in producing a strong sago uyung.

Abstract

Durian (Durio zibethinus Murr.) is a widely cultivated fruit crops in tropical region, especially in Indonesia. The nickname of this plant is King of tropical fruit. Kampar district is one of the largest producers of durian in Riau Province. Geographical location and high rain season of this region cause flooding, therefore Kampar often has periodic flooding. The purpose of this research was to determine the growth response of five cultivars of durian seedling from Kampar in various periods of inundation. Seedlings of five cultivar durian (Malukuik, Terong, Tembaga, Jantung and Kunyit) were given periodic inundation of 5 days and 10 days for 60 days with the same recovery period (5 days with 10 cm inundation height). The results showed that inundation 5 and 10 days significantly reduced all of the durian seedling growth with the observed parameters were the durian seedling height (52% and 70%), number of leaves (64% and 72%), total wet weight (27 % and 22%), root volume (43% and 33%), and root dry weight (45% and 38%). However the ratio of roots shoots increased while the interaction among durian cultivars did not show significant differences.
