Abstract

High levels of salt in the soil may cause the disruption of plant growth, especially the crops. Mustard greens (Brassica juncea L.) as the main vegetable commodity in West Kalimantan, is grown on soil with normally salinity level. The purpose of this research was to determine the growth response of mustard greens (B. juncea) against the exposure to the NaCl. The research was carried out from August to Oktober 2014. Research was carried out using the Completely Randomized Design (CRD), consisting of six treatment concentrations of NaCl i.e., 0 ppm, 2,000ppm; 4,000 ppm; 6,000 ppm; 8,000 ppm; 10,000 ppm respectively. The results showed real effects of the treatment onthe leaf area, length of the root, wet and dry weight, but had no real effect on the parameter of the number of chlorophyll. The whole treatment began to to affect the growth of mustard greens on the concentration of 4,000 ppm of NaCl. The range of tolerance of mustard green toward NaCl salt concentration was between 2,000 ppm – 10,000 ppm of NaCl.

Abstract

Kesehatan merupakan faktor kebutuhan utama manusia untuk dapat melangsungkan aktivitas hidup dengan sempurna. Kesehatan masyarakat terganggu bila terdapat kuman yang menginfeksi tubuh. Corona  atau Severe  Acute  Respiratory  Syndrome Coronavirus  2 (SARS- CoV-2) adalah virus yang menyerang  sistem pernapasan. Penyakit ini dapat menyebabkan infeksi paru-paru yang berat, hingga kematian. Data bulan April 2020, Kecamatan Pontianak Timur dilaporkan mempunyai angka kasus positif Covid-19 paling tinggi diantara kecamatan lain di Kota Pontianak.  Kelurahan di Kecamatan Pontianak Timur yang dilaporkan mempunyai angka kasus Covid-19 antara lain Kelurahan Tanjung Hulu, Kelurahan Parit Mayor, Kelurahan Banjar Serasan, Kelurahan Tambelan Sampit, Kelurahan Dalam Bugis dan Kelurahan Tanjung Hilir. Kurangnya kesadaran masyarakat tentang kesehatan dan cara mengatasi permasalahan kesehatan sangat perlu dilakukan  suatu bentuk sosialisasi dengan cara memberikan edukasi tentang permasalahan kesehatan dan cara mengatasinya. Cara yang sangat memungkinkan pada masa pandemi ini adalah dengan tidak langsung bertatap muka namun dapat dilakukan secara tidak langsung yaitu melalui leaflet dan contoh produk.  Tujuan dari kegiatan ini adalah memberikan edukasi kesehatan dalam mencegah Covid-19 kepada masyarakat. Metode yang dilakukan dalam kegiatan ini adalah memberikan edukasi dan penyuluhan melalui leaflet yaitu cara pembuatan hand sanitizer dan masker serta contoh  produk hand sanitizer dan masker yang diberikan kepada masyarakat. Sebelum pelaksanaan kegiatan, sebagian besar masyarakat (90%) di Kecamatan Pontianak Timur belum menerapkan protokol pencegahan Covid-19 yang benar. Setelah pelaksanaan kegiatan diperoleh hasil berupa peningkatan kesadaran dan pengetahuan masyarakat (100%, n=100 orang) mengenai upaya pencegahan Covid-19 serta cara pembuatan masker dan hand sanitizer.

Abstract

The use of plants in traditional medicine has been carried out by indigenous people around the forest on the island of Kalimantan. However, knowledge about the use of plants in traditional medicine by the Salako Dayak community who inhabit the buffer zone of the Raya Pasi Nature Reserve, West Kalimantan Province, has never been documented. This study aims to collect scientific information regarding the use of plants in traditional medicine by the Salako Dayak community in West Kalimantan Province. The research was conducted by conducting semi-structured interviews, and continued with a discussion of 18 respondents who were determined by purposive sampling. The data collected includes: the name of the plant, the part used, the disease/efficacy (medical) of each plant, the method of preparation of medicinal plants, and the dosage/dose rules. In addition, the frequency of citations/mentions (%) of each medicinal plant and the Informant Agreement Factor were also calculated. The results showed that the Salako Dayak community used 85 species of plants in traditional medicine. Piperaceae, Fabaceae, Rubiaceae, and Lamiaceae were the dominant plant families reported by respondents as medicinal plants. In general, the Salako Dayak community mostly uses the roots to be used as medicine, with the method of preparation by boiling or soaking. Callicarpa longifolia is the plant with the highest frequency of citations, and is commonly used to treat: internal fever, ulcers, wounds, abdominal pain, and postpartum medicine at a dose of 3 x 1. In addition, this study also obtained the number of taxa used by the Dayak community. Salako is more diverse in several categories of traditional medicine.

Abstract

Gunung Palung National Park is one of the orangutan habitats on the island of Borneo. Based on previous research, it was reported that the Kijang Pauh plant (Irvingia malayana Oliv.) grows in this conservation area. Currently, research related to plant ecology is still very limited. This study aims to determine the density and distribution pattern of the Kijang Pauh plant. Data collection was carried out from July to August 2021 in three types of orangutan habitat, namely: sandy rock habitat, alluvial habitat, and fresh water habitat. The type of research used is descriptive quantitative, where the data is presented in tabular form. Data collection was carried out by making plots measuring 50 m x 20 m with random sampling method in three types of habitat. The results showed that the density of Irvingia malayana in sandstone, alluvial, and freshwater swamp habitats was 18 individuals/ha, 10 individuals/ha, and 12 individuals/ha, respectively. The distribution pattern of Irvingia malayana in the three habitats is even or uniform. Based on the research results that have been obtained, it can be concluded that the highest density values are found in sandstone habitats, and the lowest density values are found in alluvial areas with an even or uniform distribution pattern.
