Abstract

Penggunaan pupuk kimia dengan dosis yang tinggi dan dalam jangka waktu yang panjang berdampak terhadap penurunan kesuburan lahan pertanian. Hal tersebut menyebabkan kondisi tanah menjadi asam, padat, dan mengurangi aktivitas mikroorganisme di dalam tanah, sehingga diperlukan upaya untuk mengatasi masalah kesuburan tanah, yaitu dengan penambahan bahan organik seperti pemberian pupuk kandang, kompos padat maupun pupuk organik cair (POC).  Penelitian ini bertujuan untuk : (1) mengkaji pengaruh POC daun gamal pada pertumbuhan dan produksi jagung manis, (2) mendapatkan dosis POC yang terbaik untuk  meningkatkan pertumbuhan dan produksi jagung manis.  Penelitian dilaksanakan di Kelurahan  Walian Kota Tomohon Sulawesi Utara, pada bulan April 2019 sampai dengan Agustus 2019. Penelitian disusun dengan  menggunakan Rancangan Acak Kelompok (RAK). Faktor yang diteliti adalah konsentrasi POC daun gamal, yang terdiri atas : 0,50, 100, 150, dan 200 ml per liter air. Variabel yang diamati meliputi : tinggi tanaman, jumlah daun, panjang tongkol, diameter tongkol, dan bobot tongkol.  Data dianalisis dengan analisis ragam dan dilanjutkan dengan uji beda nyata terkecil (BNT) 5%.  Hasil penelitian menunjukkan bahwa pemberian POC daun gamal berpengaruh terhadap tinggi tanaman, jumlah daun, panjang tongkol, diameter tongkol, dan bobot tongkol. Nilai tertinggi dicapai pada pemberian 200 ml POC daun gamal, dengan kenaikan panjang tongkol, diameter tongkol, dan bobot tongkol masing-masing sebesar 18,51% ; 8,03% ; 6,55% ; 5,36% dan 24,52% dibandingkan dengan kontrol.

Abstract

With an agroecological philosophy, the SRI (System of Rice Intensification) technique is a rice production technology approach that prioritizes soil, plant, and water management through local expertise and group empowerment based on environmentally beneficial activities. The purpose of this study is to investigate lowland rice growth and yield by using composted straw instead of NPK fertilizer. Implemented in Tara-Tara II village, West Tomohon sub-district for 5 (five) months with one factor treatment, namely the ratio of NPK fertilizer dose and straw compost dose: 100% NPK + straw compost 0% straw compost (P0), 75% NPK + 25% straw compost (P1), 50% NPK + 50% straw compost (P2), 25% NPK + 75% straw compost (P3), and 0% NPK + 100% straw compost (P4). The variables observed included: plant height, number of fodder, number of panicles/clumps, weight of 100 harvested dry grains, number of grains/panicles, percentage of smooth grains/clumps and harvested dry grain yield. Substitution of NPK fertilizer with compost straw has no effect on the height of lowland rice plants using the SRI (System of Rice Intensification) method, but does affect the number of productive tillers. The highest number of productive tillers was found in P2 (50% NPK + 50% straw compost), P3 (25% NPK + 75% straw compost) and P4 (0% NPK + 100% straw compost), with an average value of 31, respectively. 27; 28.20 and 27.53 tillers, while treatment P3 (25% NPK + 75% straw compost) and lower values in treatments P0 (100% NPK + 0% straw compost) and P1 (75% NPK + 25% straw compost ) with an average value of 25.83; and 25.67 offspring. Keywords: System of Rice Intensification (SRI), rice, straw compost.

Abstract. Edy Lengkong1*, Friska Malintoi 1, Jemmy Najoan1, Frangky J. Paat1, Tommy B. Ogie1, , Ronny Nangoi1. The Effectiveness Of Liquefied Organic Fertilizer (LOF) Market Waste On Increased Growth and Red-Spinach Production (Amarathus tricolor. L). Ekoton   11. 44-6. Red spinach (Amarathus tricolor L.) is a commodity that has very high development, it is proven that the number of requests tends to increase. Not inferior to other horticultural crops, red spinach plants have a fairly high economic value. Apart from being consumed every time, red spinach also contains nutrients needed by the body (Irwan et al., 2005). According to the Central Statistics Agency (BPS) in 2017, the total harvested area of ​​spinach in Indonesia in 2017 reached 40,608 hectares with a production of 160,248 tons ranks 9th out of 18 commercial vegetables cultivated and produced in Indonesia. There are 3 traditional markets in Manado City, namely Bahu Market in Malalayang District, Karombasan Market in Wanea District, and Bersehati Market in Wenang District. Can giving market waste POC affect the growth and yield of red spinach? The purpose of this study was to determine the effectiveness of giving market waste POC to the growth and yield of red spinach. And knowing the best POC concentration for the growth and yield of red spinach. It is hoped that this research can provide information on the use of market waste as a source of nutrients for the growth and yield of red spinach in the form of liquid organic fertilizer (POC). This research was arranged using a Randomized Block Design (RAK) with 5 treatments of POC concentration of market waste on red spinach plants. P0: control, P1: 25%, P2: 50%, P3: 75%, P4:100%. Each treatment consisted of 5 plant samples and was repeated 3 times to obtain 75 samples. Market waste POC with a concentration of 75% is the best concentration on the variable height of red spinach plants. Keywords: POC, Red Spinach, Market Garbage

Abstract

Jagung (Zea mays L) adalah salah satu tanaman pangan yang merupakan sumber karbohidrat utama kedua setelah beras. Metode modifikasi lingkungan mikro dapat meningkatkan produksi jagung. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh waktu pemangkasan daun di bawah tongkol terhadap tingkat produksi jagung. Studi ini dilakukan di Desa Padang, Kecamatan Bintauna, Kabupaten Bolaang Mongondow Utara, Sulawesi Utara, dari Desember 2023 hingga April 2024. Metode penelitian adalah rancangan acak kelompok dengan lima perlakuan dan tiga kali ulangan. Penelitian menemukan bahwa perlakuan pemangkasan daun di bawah tongkol adalah tanpa pemangkasan (P0), pemangkasan 60 hari setelah tanam (P1), pemangkasan 70 hari setelah tanam (P2), pemangkasan 80 hari setelah tanam (P3) dan pemangkasan 90 hari setelah tanam. Hasil penelitian menunjukkan bahwa komponen produksi pada panjang tongkol, yaitu ukuran tongkol 19,26 cm dengan diameter 5,00 cm, berat biji sekitar 241.92 g, dan jumlah biji sekitar pertongkol 617.42, meskipun berdasarkan hasil analisis sidik ragam, pengaruh tanaman jagung hanya terbatas pada panjang dan diameter tongkol.
