Susanto D, Mulyati S, Purnomo H, Ruhiyat D, Amirta R. 2017. Growth, biomass production and nutrient accumulation of Macaranga gigantea in response to NPK fertilizer application. Nusantara Bioscience 9: 330-337. Research described in this paper investigated the effect of fertilizer application on the growth, biomass production and nutrient accumulation of mahang (Macaranga gigantea) plant components. The experiment was carried out in a research area of the Faculty of Forestry, Mulawarman University, Samarinda, East Kalimantan. The effects of five dose levels of an NPK (16-16-16) fertilizer on the growth rate of mahang seedlings planted in field conditions were compared. The treatments consisted of a control group (with no fertilizer), and dosages of 40 g, 80 g, 120 g and 160 g per plant. Fertilization at those levels was applied twice: the first application at four weeks after the planting and the second application at 6 months after the first. Growth rates between treatments were compared over a twelve month period. The research findings revealed that as the dosages of fertilizer increased, so the growth, biomass production and nutrient accumulation in components of the plants also increased. The best growth was found in the treatment in which fertilizer was applied (twice) at a dosage of 120 g per plant; at this dose level, by twelve months of age, the stem basal diameter had reached 45.24.9 cm, stem height 219.239.1 cm, number of leaves per plant 17.31.2, and canopy diameter 246.725.0 cm. The highest production of above-ground biomass was also found in the fertilizer treatment of 120 g per plant; the largest proportion of the biomass was in the leaves, followed by the wood, and then bark. The nutrient element that had accumulated most in plants at 1 year of age was potassium, followed by phosphorus and then nitrogen. The highest nitrogen uptake of stands was found in the NPK fertilization with a dosage of 160 g per tree, while the highest phosphorus and potassium uptake was found at a fertilizer dosage of 120 g per tree. The amount of nutrients accumulated in producing one tonne of above-ground biomass increased in response to different fertilization treatments. The fertilizer treatment of 120 g per plant (applied twice; the first soon after planting and the next after 6 months) resulted in the accumulation within the 1 year old plants of 2.38 kg of nitrogen, 6.36 kg of phosporus and 17.83 kg of potassium, with an N:P:K ratio of 13.3 : 35.6 : 100. The availability of the element potassium needs special attention when this species is cultivated.
Permasalahan yang mengakibatkan penurunan produktifitas hasil panen tanaman sayuran salah satunya akan adanya keberadaan hama. Pemasalakan keberadaan hama masih terus terjadi dilahan pertanian, salah satunya pada lahan sayuran. Penelitian ini bertujuan untuk mengetahui efektifitas pestisida alami kulit bawang merah terhadap pengendalian hama ulat tritip pada tanaman sayur sawi hijau. Jenis penelitian ini digunakan ekperimen murni dengan desain “Post test control group design” pecobaan terdiri dari 3 perlakuan konsentrasi pestisida alami kulit bawang merah (40%, 60% dan 90%), dan 1 perlakuan tanpa pestisida alami kulit bawang merah sebagai kontrol. Semua pelakuan disiapkan 3 pengulangan. Pengamatan hama pada tumbunhan sayur sawi hijau pada saat 13, 19 dan 25 hari setelah tanam. Hasil penelitian ini menunjukan bahwa pestisida alami kulit bawang merah efektif terhadap pengendalian hama ulat tritip pada tanaman sayur sawi hijau. Kulit bawang merah dapat dimanfaatkan sebagai alternatif pestisida alami baru dalam pembutaan pestisida alami karna tiding mengandung bahan kimia dan jauh lebih aman bagi lingkungan.
During the Covid-19 pandemic, education, which so far has been carried out directly, has switched to education through various online media, but the effectiveness of education through these applications needs to be evaluated. The aim of the study was to increase pregnant women's knowledge about exclusive breastfeeding and to find out the effect of android-based application programs on breastfeeding patterns. The research design was quasi-experimental with a pre and post-test control group design, subjects were grouped into intervention groups and control groups, selected by purposive sampling with a total of 30 people in each group. This research was conducted in 2022 in the Sindang Barang and Cipaku Health Centers, Bogor City. The independent variable is the Android-based ASI application program with the dependent variable being the pattern of breastfeeding. The statistical test uses the Wilcoxon and Mann Whitney tests. The results of the study showed that there was a significant increase in the average knowledge and attitude after exclusive breastfeeding education was carried out with Android-based application program, as well as a significant change in the pattern of breastfeeding after participating in the breastfeeding education program. The conclusion of the study is that there is a significant relationship between breastfeeding education and Android-based application program on increasing knowledge, attitudes of mothers and patterns of breastfeeding.
Demam Berdarah Dengue (DBD) adalah penyakit yang disebabkan oleh virus Dengue yang tergolong Arthropod-Borne virus genus Flavivirus, dan famili Flaviviridae. Daun salam (Syzygium polyanthum). Tujuan dalam penelitian ini adalah diketahui konsentrasi efektif daun salam (Syzygium polyanthum) sebagai larvasia nyamuk aedes sp. Metode Penelitian ini merupakan rancangan penelitian eksperimen sungguhan (True Experiment) dengan rancangan posttes dengan kelompok control (“ Posttes Only Control Group Design") dengan dianalisis secara deskriptif dan analitik. pengumpulan data secara langsung yang diperoleh dari jumlah kematian nyamuk dan observasi selama penelitian. Penelitian ini didapatkan hasil bahwa konsentrasi 2%, 3%, 4%, 5% paling efektif dalam membunuh larva nyamuk Aedes sp pada konsentrasi 5% mampu membunuh 89,6% larva nyamuk Aedes sp. Diharapkan masyarakat untuk menggunakan insektisida alami seperti ektrak daun salam (Syzygium polyanthum) dalam mematikan larva nyamuk Aedes sp sebagai pengganti insektisida kimiawi.
Kelurahan Kramas merupakan salah satu wilayah Binaan/Desa Binaan Jurusan Teknik Radiodiagnostik dan Radioterapi. Pengembangan kemitraan Desa Binaan ini dilakukan oleh civitas akademika Prodi D-IV Teknik Radiologi Jurusan TRR sebagai wujud pelaksanaan Tri Dharma PT, khususnya untuk Pengabdian kepada Masyarakat. Sinergi dari PT dan wilayah Binaan diharapkan dapat meningkatkan kesejahteraan bagi masyarakat di wilayah Binaan atau mengatasi permasalahan yang ada di dalam masyarakat. Oleh karena itu perlu adanya kegiatan pelatihan dan pendampingan guna meningkatkan produktivitas kegiatan pengolahan jamu tradisional berbahan dasar jahe dan temulawak ini nantinya diharapkan dapat membantu meningkatkan kesejahteraan bagi warga kampung tematik khususnya dan wilayah Kramas pada umumnya. Metode pengabdian masyarakat ini dilakukan dengan memberikan penyuluhan dan pendampingan terkait produksi makanan-minuman terkait industri rumah tangga dengan nara sumber dari Dinas Kesehatan Kota Semarang, cara pengajuan ijin PIRT, cara membuat produk memiliki brand/labelling. Mitra kegiatan ini adalah Kelurahan Kramas kecamatan Tembalang Kota Semarang dan Dinas Kesehatan Kota Semarang. Selain itu dilakukan pendampingan secara berkala di masyarakat Kramas yang merupakan kampung tematik Jahe-Temulawak di Kecamatan Tembalang Kota Semarang. Setelah dilakukan penyuluhan dan pendampingan tentang pengolahan bahan pangan-jamu tradisional, minuman dan makanan kemasan dan lain-lain warga sangat antusias mengikuti kegiatan ini. Dan semangat untuk mendaftarkan produknya yang berpeluang untuk pengajuan PIRT untuk produk yang tahan lama, sementara jamu minuman kemasan tidak membutuhkan PIRT. Dengan adanya pengolahan yang benar, labelling, dan packaging yang menarik yang diproduksi oleh warga kampung tematik Jahe-Temulawak ini diharapkan dapat memiliki daya ungkit untuk menambah nilai ekonomis, atau harga jual produk dengan pangsa pasar yang lebih luas.
