Abstract

Water quality is the nature of the water and the content of living beings, substances, energy, or other components in the water. Water quality in general is shown by the quality or the condition of the water that is associated with an activity or specific purposes. Water quality will be different from one activity to another. The quality of the water for purposes of irrigation with different water quality for drinking water purposes. The irrigation water used for agriculture should meet the quality standards of irrigation water according to Government Regulation No. 82 years 2001 is included in class IV so that the quality of irrigation water deserves to be watering for plants. Keywoards:  irrigation; water.  AbstrakKualitas air adalah sifat air dan kandungan makhluk hidup, zat, energi atau komponen lain di dalam air. Kualitas air secara umum ditunjukkan oleh mutu atau kondisi air yang dikaitkan dengan suatu kegiatan atau keperluan tertentu. Kualitas air akan berbeda dari suatu kegiatan ke kegiatan lain. Kualitas air untuk keperluan irigasi berbeda dengan kualitas air untuk keperluan air minum. Air irigasi yang digunakan untuk pertanian sebaiknya memenuhi baku mutu air irigasi sesuai Peraturan Pemerintah Nomor 82 tahun 2001 termasuk dalam kelas IV sehingga kualitas air irigasi layak dijadikan pengairan untuk tanaman. Kata kunci:  irigasi; air.

Abstract

   Land kale (Ipomoea reptana poir) is one of the horticultural plants that are very popular among Indonesians because of its savory taste. This plant belongs to a group of plants a short-lived season and does not require a large area so that it allows cultivated on limited land for example by using polybags. NASA POC is one type of fertilizer that can be given to leaves and soil, containing complete macro and micro nutrients. The purpose of this study was to look at the influence of NASA POC and obtain the best concentration for the growth and production of land kale plants (Ipomoea reptana poir). The research was conducted in Lebani Village, North Sangalla District, Tana Toraja Regency, South Sulawesi Province starting from April-May 2021. The design used is a Complete RandomIzed Design (RAL) with 4 treatments namely A0, A1, A2 and A3 with 4 replays so that 16 experimental plants are obtained. The results showed that statistically the concentration of treatment has no real effect, but visually NASA POC fertilizer affects the growth of plants, namely the height of plants, the number of leaves, the length of leaves and the production of land kale plants that is fresh weight and the treatment of NASA POC concentration of 1 ml /100 ml of water is visually the best concentration for the cultivation of kale plants in polybags.Keywords: NASA POC and Land Kale Plant AbstrakKangkung darat (Ipomoea reptana poir) merupakan salah satu tanaman hortikultura yang sangat digemari oleh masyarakat Indonesia karena rasanya yang gurih. Tanaman ini termasuk kelompok tanaman semusim berumur pendek dan tidak memerlukan areal yang luas sehingga memungkinkan dibudidayakan pada lahan yang terbatas dengan menggunakan polybag. POC NASA adalah salah satu jenis pupuk yang bisa diberikan ke daun dan tanah, mengandung unsur hara makro dan mikro lengkap. Tujuan penelitian ini adalah untuk melihat pengaruh POC NASA dan memperoleh konsentrasi yang terbaik untuk pertumbuhan dan produksi tanaman kangkung darat (Ipomoea reptana poir). Penelitian di dilaksanakan di Desa Lebani, Kecamatan Sangalla Utara Kabupaten Tana Toraja Provinsi Sulawesi Selatan mulai dari bulan April-Mei 2021. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan yaitu A0,A1,A2 dan A3 dengan 4 ulangan sehingga di peroleh 16 tanaman percobaan. Variabel pengamatan yang diukur adalah tinggi tanaman (cm),jumlah daun (helai),panjang daun (cm) dan berat segar pada saat panen (gr). Hasil penelitian menunjukkan bahwa secara statistik konsentrasi perlakuan tidak berpengaruh nyata, namun secara visual pupuk POC NASA berpengaruh terhadap pertumbuhan tanaman yaitu tinggi tanaman, jumlah daun, panjang daun dan produksi tanaman kangkung darat yaitu berat segar dan perlakuan konsentrasi POC NASA 1ml/100 ml air secara visual merupakan konsentrasi yang terbaik untuk budidaya tanaman kangkung pada polybag.Kata kunci : POC NASA dan Tanaman Kangkung Darat

Abstract

This Zingiberaceae plant is widely used as medicine, including temulawak. Because curcuma (C.xanthorrhiza) is a medicinal plant that has many benefits and includes plants needed in large quantities compared to other medicinal plants. Traditionally rhizomes Temulawak is used to treat stomach ailments, liver disorders, constipation, diarrhea, dysentery, fever, hemorrhoids, hypotriglyceridaemic, and anti-inflammatory. Study about plant Curcuma local ignite still not enough researched so that not yet get information compounds which contained in the local curcuma of North Sulawesi for the development for biopharmaceutical development, mapping in the distribution of plants, ecology, plant conservation and protection to maintain local wisdom. Histochemical Test is a method to determine the content of chemical compounds in a plant tissue qualitative. Testing can be done by adding a special reagent or solution to the incision organ plant and will give color which Specific. Activity study this will test curcumin compound group on local ginger from North Sulawesi by histochemical method. research that done is study non experiment with design descriptive qualitative. The results showed that North Sulawesi local white temulawak powder contained curcumin in a sample with a sample weight of 0.10 g at a sample spotting volume of 20 µl with a sample spotting volume of 2040 nanograms, curcumin levels were <0.10 nanograms/mg. Curcumin biosynthesis is influenced by site conditions, agro-climate, genotype, and plant cultivation.

Abstract

Indonesia has a variety of medicinal plants that are efficacious for preventing or treating various diseases. Each region has unique medicinal plants, such as in North Sulawesi, there are many medicinal plants with local names of "Jarak" (Jatropha curcas), "Jarak Merah" (Jatropha multifida), "Miana" (Coleus Scutellarioide), and "Sesewanua" (Clerodendron Squmatum Vahl). This research applies the Convolutional Neural Network (CNN) method to identify the types of medicinal plants of North Sulawesi based on leaf images. Data was collected directly by taking photos of medicinal plant leaves and then using the augmentation process to increase the data. The first stage is conducting training and validation processes using 10-fold cross-validation, resulting in 10 classification models. Evaluation results show that the lowest validation accuracy of 98.4% was obtained from fold-4, and the highest was 100% from fold-2. The third stage was to run the testing process using new data. The results showed that the worst model produced a test accuracy of 80.91% while the best model produced an accuracy of 87.73% which means that the identification model is quite good and stable in classifying types of medicinal plants based on its leaf images. The final stage is to develop a web-based system to deploy the best model so people can use it in real-time
