Abstract

Calcarosol merupakan istilah yang merujuk pada tanah-tanah yang terbentuk di atas formasi batuan kapur (limestone). Permasalahan utama yang ditemui dalam kegiatan budidaya jagung di tanah Calcarosol adalah ketersediaan hara fosfor (P) yang rendah. Aplikasi pupuk organik dan pupuk hayati diketahui dapat meningkatkan hara P pada tanah Calcarosol melalui beberapa mekanisme. Penelitian ini dilakukan dengan tujuan untuk menguji keefektifan paket pemupukan organik dan hayati (PPOH) dalam menekan penggunaan pupuk P-anorganik (SP-36) pada Calcarosol di Timor Barat. Penelitian dilaksanakan melalui kegiatan percobaan di lahan milik petani di Kelurahan Penfui, Kecamatan Kelapa Lima Kota Kupang dengan menggunakan rancangan acak lengkap (RAL).  Perlakuan yang dicobakan meliputi: tanpa aplikasi pupuk (P0); PPOH tanpa penambahan pupuk sintetis (P1);  PPOH + 50 kg/ha SP 36 (P2);  PPOH + 100 kg/ha SP-36 (P3); PPOH + 150 kg/ha SP-36 (P4); PPOH + 200 kg/ha SP-36 (P5); dan PPOH + 250 kg/ha (P6). Hasil penelitian menunjukkan: (1) kandungan hara P jaringan tanaman pada perlakuan aplikasi PPOH + 50 kg/ha SP-36  yang tidak berbeda secara signifikan dengan perlakuan PPOH + 250 kg/ha SP-36 membuktikan bahwa dengan aplikasi PPOH, penggunaan pupuk SP-36 dapat dikurangi hingga 80% dari dosis yang umum digunakan oleh petani untuk memenuhi kebutuhan hara P tanaman; (2) bobot biji pipilan kering jagung pada perlakuan PPOH saja yang tidak berbeda secara signikan dengan perlakuan PPOH + 250 kg/ha SP-36 membuktikan bahwa aplikasi PPOH mampu mensubtitusi penggunaan pupuk SP-36 di tanah Calcarosol pada musim tanam pertama pasca aplikasi.

Abstract

Kesuburan tanah yang rendah menjadi salah satu faktor pembatas rendahnya produksi jagung di Pulau Timor. Hal ini terutama terkait dengan ketersediaan unsur hara fosfor (P) yang rendah yang umumnya diatasi oleh petani melalui penggunaan pupuk P-anorganik. Namun demikian, kondisi tanah yang berkapur dapat menurunkan ketersediaan hara P bagi tanaman sehingga pupuk P-anorganik memiliki efisiensi yang rendah. Tujuan penelitian ini untuk mendapatkan dosis pupuk fosfor (P) anorganik dan inokulasi kelompok FMA yang memberikan pengaruh terbaik terhadap serapan hara P, pertumbuhan dan hasil tanaman jagung. Penelitian dilaksanakan di lahan pertanian di Desa Penfui Timur, Kabupaten Kupang dan Laboratorium Fisika dan Kimia Tanah Fakultas Pertanian Universitas Nusa Cendana Kupang. Penelitian ini dirancang dalam percobaan faktorial 2 faktor menggunakan rancangan lingkungan berupa rancangan petak terpisah (spit plot design) dengan 3 ulangan. Petak utama adalah inokulasi FMA (M) yang terdiri dari 3 taraf: tanpa inokulasi FMA (M0), inokulasi satu jenis spora FMA (M1), dan inokulasi spora FMA campuran (M2). Anak petak adalah dosis pupuk P (SP-36) (P) yang terdiri dari 4 taraf: 25% (P1), 50% (P2), 75% (P3), dan 100% (P4) dosis anjuran. Variabel yang diamati adalah kandungan hara P-jaringan tanaman, tinggi tanaman dan bobot 100 butir jagung pipilan kering. Hasil penelitian menunjukkan: (1) interaksi perlakuan inokulasi FMA dengan perlakuan dosis pupuk P-anorganik tidak berpengaruh nyata terhadap semua variabel pengamatan; perlakuan tunggal inokulasi FMA berpengaruh nyata terhadap tinggi tanaman dan bobot 100 butir jagung pipilan kering namun tidak berpengaruh nyata terhadap kandungan hara P jaringan tanaman; perlakuan tunggal dosis pupuk P-anorganik hanya berpengaruh nyata terhadap kandungan hara P-jaringan tanaman namun tidak berpengaruh nyata terhadap tinggi tanaman dan bobot 100 butir jagung pipilan kering, (2) inokulasi FMA baik tipe spora tunggal maupun tipe spora campuran belum mampu meningkatkan kandungan hara P jaringan tanaman namun mampu meningkatkan tinggi tanaman dan bobot 100 butir jagung pipilan kering; tidak terdapat perbedaan nyata antara perlakuan inokulasi FMA tipe spora tunggal dengan perlakuan tipe spora campuran dalam meningkatkan tinggi tanaman dan bobot 100 butir jagung pipilan kering sehingga tidak didapatkan perlakuan inokulasi FMA terbaik dalam penelitian ini, dan (3) tidak didapatkan perlakuan dosis pupuk P-anorganik yang memberikan pengaruh terbaik dalam meningkatkan serapan hara P, pertumbuhan, dan hasil tanaman jagung pada penelitian ini berkaitan dengan efisiensi pemupukan P-anorganik yang rendah pada lahan berkapur.

Abstract

This research was conducted at the Dryland Laboratory of Nusa Cendana University Kupang from September to December 2022. The purpose of this study was to determine the effect of interaction of doses of solid bokashi fertilizer made from a mixture of kirinyu and banana stem and hormonic concentration on the growth and yield of Cauliflower and determining the combination of those interaction that provides the best growth and yield of Cauliflower plants. This research was a factorial experiment, using Randomized Complete Block Design (RCBD) with three blocks and consisting of nine treatment combinations per blocks. The observed variables were plant height increse (cm), increase in leaves number, increase in stem circumference (cm), gross weight (g) and net weight (g). The observation data were analyzed by analysis of variance (ANOVA) and and followed by DMRT test (significant level 0.05%). The results showed that the interaction between the application of doses of bokashi and hormone concentration significantly affected the increase in height, increase in leaf number, and net fresh weight of cauliflower plants. The combination of treatment doses of bokashi at 10 tons/ha with a hormone concentration of 8 cc/L was the best interaction, with a net fresh weight of cauliflower plants reaching 265.71 g/ plant.

Abstract

Increased plant productivity can be achieved through the development of organic fertilization technology that utilizes local organic matter that is easily accessible to farmers. An example is the use of manure from cow and goat manure, as well as forage such as kirinyuh and gamal. This approach offers a solution to the low productivity of rice in drylands. The use of organic fertilizers in various doses is expected to improve soil nutrient status while increasing rice productivity in dry land. This research was carried out on farmers' land in Ponu Village, Biboki Anleu District, North Central Timor Regency, East Nusa Tenggara, which is located in the RI-RDTL border area, precisely the Oekusi section. The experiment in this study was designed in a Group Randomized Design consisting of 10 treatments. The treatment is No Fertilization (P0D0), 10 tons of cow manure fertilizer (PsD1), 20 tons of cow manure fertilizer (PsD2), 30 tons of cow manure (PsD3), 10 tons of goat manure (PkD1), 20 tons of goat manure (PkD2), 30 tons of goat manure (PkD3), 10 tons of forage (PhD1), 20 tons of forage (PhD2), and Forage fertilizer with a dose of 30 tons (PhD3). Each treatment was repeated 4 times so that there were 40 experimental plots. The results showed that the combination of goat manure treatment with a dose of 30 tons/ha (PkD3) had a better effect than other treatment combinations. This combination of treatments was able to provide the best observation value on several parameters, namely plant height growth, the number of saplings and the number of panicles per clump as well as the production of dry grain weight harvested per plot.

Abstract

Around 20% of mangrove forests in Indonesia are in a degraded condition, which has a negative impact on the potential for blue carbon storage. When mangroves are damaged or degraded, carbon stored in the soil and vegetation can be released back into the atmosphere as CO2, ultimately increasing greenhouse gas emissions and exacerbating climate change. Mangrove forests can store up to four times more carbon per hectare, around 8001,200 tons per hectare, than terrestrial tropical forests. This research was conducted in the Wini mangrove forest area, North Central Timor, East Nusa Tenggara (NTT) which directly borders Timor Leste. The determination of the location of the observation station was based on a map of changes in mangrove forest land use obtained from the Geospatial Information Agency. The parameters measured included organic carbon, mangrove area and sediment type. Organic carbon was analyzed using the Loss on Ignition (LOI) method, and sediment grain size was measured using a particle size analyzer. The results of the study showed that the average organic carbon stock in mangrove forests reached 570,600843,600 tons per hectare, with an average change in the area of mangrove forests from 2013 to 2023 of 181.29 hectares and the type of sediment dominated by sandy mud. This change in area is caused by the conversion of mangrove land into ponds, rice fields, and settlements.Keywords:MangroveCarbonSedimentborder Area

Abstract

Soybean production in Indonesia has not shown a satisfactory trend, compounded by drought problems that adversely affect plant growth and metabolism. One of the various solutions offered is the use of drought-resistant/tolerant soybean varieties. This study aims to examine how drought-resistant/tolerant varieties differ from drought-susceptible varieties in their morphophysiological response to drought. The study was conducted in a plastic house in Aras Kabu Village, Beringin Subdistrict, Deli Serdang Regency, North Sumatra, using a randomised block design with two factors and three replicates. The first factor was soil moisture conditions, consisting of 80% field capacity (FC) and 40% FC. The second factor was the testing of the Grobogan and Dering varieties. The observation parameters consisted of the number of leaves and leaf K uptake. The results showed that there was a significant interaction between the use of varieties and drought conditions, where the Dering variety significantly reduced the number of leaves, while the Grobogan variety, which is susceptible to drought, increased leaf K uptake to survive. Keywords: soybean, drought, stress, varieties
