Purslane (Portulaca oleracea L.) is a weed that can be used as a source of natural antioxidants. One of the ingredients in purslane is ascorbic acid (vitamin C). One of the preventive measures related to infections caused by the coronavirus is taking vitamin C to support the body’s immunity, which is proven to have a positive effect on the body’s immunity. Vitamin C can prevent susceptibility to reduce respiratory infections in certain conditions. The objective of this study was to get purslane plants (Portulaca oleracea L.) as a source of quality bioactive components of ascorbic acid (vitamin C) from various altitudes in East Java, Indonesia. The study conducted by taking purslane planting material in the lowlands 3 m above sea level (Rungkut, Surabaya); medium plains 593 m above sea level (DAU, Malang), and highlands 945 m above sea level (Bumi Aji, Batu Malang). Vitamin C analysis was carried out using LCMS (Liquid chromatography-mass spectrometry). The results of this study were the analysis of the content of purslane (Portulaca oleracea L). ascorbic acid (Vitamin C) from three altitudes was at highlands 9.24 mg/kg, medium plains 2.40 mg/kg, and lowlands 9.73 mg/kg.

<p>This study aims to obtain purslane plants as a source of local food and a quality bioactive component from various altitudes in East Java, Indonesia. Purslane planting materials were collected from the lowlands &lt;200 m asl in Surabaya, medium plains 200-800 m asl in Malang DAU, and highlands&gt; 800 m asl in Batu, Malang. Analysis of vitamin E was as total tocopherol. The results of the analysis of the content of <em>Portulaca oleraceae</em> L. of vitamin E were as followed: in the highlands 0.1056%, medium lands 0.1253%, and lowlands 1.162%. The analysis showed that <em>Portulaca oleraceae</em> L. could be a source of high quality local food and bioactive components because it contains vitamin E and antioxidants.</p><p>Keywords<strong>:</strong> bioactive components; local food; lowland.<strong></strong></p><p> </p>

Purslane has many benefits as food or raw material for medicine. It is rich in beneficial compounds, such as omega-3 and vitamins. However, it has not been cultivated yet. Organic input in cultivation is essential to ensure food safety for humans. Using organic inputs can avoid the yield from chemical and biological contaminants that can threaten health. Thus, the source of growing media and fertilizer must be considered. Because the use of synthetic chemicals has residues that are harmful to the environment and human health. This research sought to identify the best combination of growing media and organic fertilizer to increase purslane yield. The experiment was conducted with a randomized block design with 2 factors and 3 replications. Organic fertilizers (guano, cow urine, and rabbit urine) and planting media (soil, soil + husk charcoal, soil + compost, and soil + husk charcoal) were the treatments assessed. The observation variables were planting media analysis, the number of leaves and branches, growth diameter, and fresh weight. The results show that the planting medium and organic fertilizer did not significantly affect the measured growth parameters. The single variable of organic fertilizer made a difference in growth diameter and fresh weight. Rabbit urine produced in the highest growth diameter, and guano produced in the highest fresh weight The single variable of organic fertilizer made a difference in growth diameter and fresh weight. Rabbit urine produced in the highest growth diameter, and guano produced in the highest fresh weight The single variable of organic fertilizer made a difference in growth diameter and fresh weight. Rabbit urine produced in the highest growth diameter, and guano produced in the highest fresh weight

The problem is the abundance of untapped teak wood waste that has an impact on environmental pollution. The purpose of this community service activities is to develop an agro-industrial area and become a marketing platform for wood waste processing products. The service activities include: (1) programing preparation and socialization stage, (2) programing and to do exhibition assistance training, (3) monitoring and evaluation, (4) Marketing and promotion. The results obtained from processed teak waste are in the form of vehicle souvenirs such as cars, vespa, motorbikes, rickshaws, mineral water containers, fruit containers, and ashtrays which have been exhibited as superior products at the sub-district level. This program is implemented by UPN Veteran East Java together with Soerja Ngawi University and the Ngawi Food Security Agency. Activities carried out include comparative studies, mentoring, apprenticeship, procurement of tools and training for making souvenirs from waste, and marketing for groups of craftsmen. Waste processing is beneficial for the community in increasing knowledge and skills, increasing community income, and making the regional superior product of Ngawi Regency. Environmental pollution can be overcome by utilizing waste into superior products.

Mikoriza arbuskula adalah mikrobia tanah yang memiliki peran dalam meningkatkan ketersediaan air bagi tanaman melalui perpanjangan hifa sehingga dapat menjangkau pada daerah yang lebih luas. Mikoriza arbuskula merupakan mikrobia tanah yang dapat berkembang pada sistem agroforestri dan monokultur. Informasi mikoriza yang dapat bersimbiosis dengan Porang baik secara agroforestri dan monokultur belum banyak dipublikasikan. Oleh sebab itu perlu identifikasi spora yang ada di rizosfer Porang sehingga nantinya dapat dijadikan sebagai bahan baku pupuk berbasis mikoriza arbuskula untuk tanaman Porang. Penelitian ini bertujuan untuk mengidentifikasi mikoriza arbuskula yang berada di rizosfer Porang pada berbagai sistem pertanaman. Penelitian tentang fungi mikoriza arbuskula di rizosfer Porang dilakukan di lahan agroforestri dan monokultur yang memiliki jenis  tanah latosol. Lahan penelitian berada di Desa Mrayan, Kecamatan Ngrayun kabupaten Ponorogo Jawa timur Indonesia dan dilakukan pada bulan Desember 2020. Sampel tanah diambil secara acak di tiga lahan yang berbeda yaitu agroforestri berbasis pinus, agroforestri berbasis sengon dan monokultur. Sampel tanah diambil disekitar perakaran tanaman Porang. Sampel akar berupa akar halus porang. Spora mikoriza arbuskula diektrak dengan metode pengayaan basah dan kering. Identifikasi spora mikoriza arbuskula dilakukan dengan identifikasi morfologi. Hasil penelitian ini ditemukan 3 genera yang terdiri dari 9 species yaitu Glomus (5 species), Acaulospora (2 speies) dan Gigaspora (2 species).  Kepadatan  spora tertinggi berjenis Glomus dan yang terkecil adalah Gigaspora.  Rata rata kepadatan spora adalah 56-105 spora/100 g tanah. Kepadatan spora tertinggi pada agroforestri berbasis pinus. Persentase infeksi akar berkisar antar 24-50%.  Persentase infeksi akar tertinggi pada agroforestri berbasis sengon.
