Abstract

A better understanding of variability in plant populations is crucial for crop improvement which plant breeders can use through selection. This study aimed to determine selection criteria for the sixth generation of black rice through genetic variability, heritability value and genetic advance. This research was conducted from March to July 2018 at Pakahan Village, Jogonalan Sub-district, Klaten Regency, Central Java, using a Randomized Complete Block Design (RCBD). The variables observed were plant height, total number of tillers and productive tillers, panicle length, number of seeds per panicle, panicle intensity index, weight per panicle, 1,000 seed weight, seed weight per plant, flowering age, harvest age, plot yield, yield per hectare, rice color and total anthocyanin content. Variance analysis showed that there was a very significant difference (p <0.01) among the genotypes tested for all observed characters indicating variability. In this study, the phenotypic coefficient of variance (PCV) values was relatively higher than the genotypic coefficient of variance (GCV) for all traits. However, GCV values were close to PCV values in some characters such as plant height, flowering age, harvest age, rice color and anthocyanin content which showed a high contribution of genotypic effects to the phenotypic expression of these characters. The high heritability and high average value of genetic advance were indicated in the parameters of plant height, flowering age, harvest age, rice color and anthocyanin content. The characters of plant height, flowering age, harvest age, rice color and anthocyanin content can be used as sixth-generation black rice selection criteria.

Abstract

This study aims to determine the effect of kinds and dosage of manure application on the growth and yield of pakchoy. The experiment was conducted in a the field of Merapi Organic Farm, located in Balangan Wukirsari village, Cangkringan, Sleman Yogyakarta. The altitude is 500 meters above sea level with temperature of 23 0C - 29 0C and regosol soil type. This research was conducted in October through December 2016. The experiment was a factorial 2 x 3 and one control, arranged in a randomized complete block design. The treatment consists of two factors, the first factor consists of two kinds: namely  vermicompost and cow manure. The second factor is the dose of organic manure: 5 ton, 10 ton and 15 ton per hectare. Each treatment was repeated three times. Variables observed were plant height, leaf number, leaf area, plant fresh weight, root fresh weight, dry weight of plants, root dry weight and yield per hectare. The analysis showed that no interaction effect between the two factors on the growth and yield. Various kinds and dose of  manure showed no significant effect on the growth and yield, per hectare. The application of manure significantly affected plant height and plant fresh weight.

Abstract

Pemberdayaan kelompok tani dengan sasaran Kelompok Tani Cemerlang Desa Panca Mulya, Kecamatan Air Kumbang, Kabupaten Banyuasin, Sumatera Selatan merupakan program pengabdian kepada masyarakat yang didanai oleh LPPM Universitas Muhammadiyah Palembang melalui skema Bina Desa dengan mengatasi permasalahan yang dihadapi oleh kelompok tani Cemerlang yang berada di Desa Panca Mulya, kecamatan Air Kumbang, Kabupaten Banyuasin antara lain masih rendahnya ketrampilan petani dalam membuat pupuk organik cair denga bahan baku kotoran sapi serta terjadinya kelangkaan pupuk anorganik. Upaya yang dapat dilakukan untuk menjawab permasalahan kelompok tani tersebut yaitu dengan kegiatan pelatihan pemanfaatan kotoran sapi sebagai bahan baku pembuatan pupuk organik cair. Pupuk organik cair memanfaatkan sumber daya alam sekitar karena bahan baku yang digunakan relatif banyak di desa tersebut. Dengan adanya kegiatan pemberdayaan kelompok tani ini, anggota kelompok tani Cemerlang Desa Panca Mulya menjadi lebih terampil dan mampu membuat pupuk organik cair.

Abstract

Penelitian ini bertujuan untuk mengetahui dan menentukan komposisi media tanam dan konsentrasi pupuk organik cair yang tepat dalam meningkatkan hasil tanaman bawang merah (Allium ascalonicum L.). Penelitian ini telah dilaksanakan di lahan milik petani yang terletak di jalan Sukarela, Kelurahan Kebun Bunga, Kec. Sukarami,  Km 7 Palembang Sumatera Selatan. Penelitian ini telah dilaksanakan dari bulan April sampai Juli 2022. Penelitian ini menggunakan metode eksperimen dengan Rancangan Acak Kelompok (RAK) Faktorial terdiri dari 9 kombinasi perlakuan yang di ulang 3 kali. Adapun perlakuan yang dimaksud adalah sebagai berikut Faktor 1 : komposisi media (M) yaitu M1 = 1 : 1 : 1 ;  M2 = 1 : 2 : 1 ; M3 = 1 : 1 : 2 sedangkan Faktor 2 : pupuk organik cair (N) yaitu N1 = 3 ml/L ; N2= 5 ml/L ; N3= 8 ml/L. Peubah yang diamati dalam penelitian ini adalah jumlah umbi perumpun (umbi), berat umbi perumpun (g) dan berat umbi perperlakuan (g). Berdasarkan hasil  penelitian menunjukkan bahwa secara tabulasi perlakuan kombinasi komposisi media tanam 1 : 1 : 2 dan konsentrasi pupuk organik cair 8 ml/L memberikan hasil tertinggi sebesar 443,33 g. This study aims to identify and determine the composition of the planting medium and the appropriate concentration of liquid organic fertilizer to increase the yield of shallots (Allium ascalonicum L.). This research was carried out on farmer's land located on Jalan Sukarela, Kelurahan Kebun Bunga, Kec. Sukarami, Km 7 Palembang, South Sumatra. This research was conducted from April to July 2022. This research used an experimental method with a Factorial Randomized Block Design (RBD) consisting of 9 treatment combinations which were repeated 3 times. The treatment referred to is as follows. Factor 1: composition of the media (M), namely M1 = 1 : 1 : 1 ; M2 = 1 : 2 : 1 ; M3 = 1 : 1 : 2 while Factor 2 : liquid organic fertilizer (N), namely N1 = 3 ml/L ; N2 = 5 ml/L ; N3 = 8 ml/L. The variables observed in this study were the number of tubers (tubers), the weight of the tubers (g) and the weight of the treated tubers (g). Based on the results of the study, it was shown that in tabulation, the combination treatment of the composition of the planting medium 1: 1: 2 and the concentration of liquid organic fertilizer 8 ml/L gave the highest yield of 443.33 g.

Abstract

Lahan pasca tambang pada umumnya merupakan lahan yang telah mengalami kerusakan akibat kegiatan penambangan.  Kerusakan yang terjadi pada lahan pasca tambang antara lain terjadinya perubahan sifat fisik, kimia maupun biologi tanah yang mengakibatkan turunnya produktifitas lahan, terjadinya perubahan perubahan bentang alam lahan,  kedalaman efektif tanah menjadi dangkal, dan terbentuknya lapisan lapisan tanah yang baru yang berisi pasir, kerikil, sisa-sisa tailing yang nantinya akan terbentik lapisan cadas.  Salah satu cara untuk memperbaiki kerusakan lahan pasca tambang yaitu dengan mereklamasi dan mengalihfungsikan lahan pasca tambang menjadi lahan pertanian. Tujuan kajian ini untuk mengkaji berbagai lahan reklamasi pasca tambang yang dapat dialihfungsi menjadi lahan pertanian berdasarkan analisa tingkat kesuburan tanah. Metode penelitian yang digunakan adalah metode kualitatif analisis dan analisa komparatif yaitu dengan cara mengumpulkan, memilah dan membandingkan data yang didapat dari beberapa jurnal maupun buku (studi literatur). Hasil kajian menunjukkan bahwa beberapa lahan pasca tambang dapat diubah menjadi lahan pertanian, hal ini tergantung dari lokasi, kekhasan sifat dan karakteristik lahan pasca tambang, seperti lahan reklamasi pasca tambang batubara dengan tingkat kesuburan tanah yang cukup baik.Post-mining land is generally land that has been damaged by mining activities. Damage that occurs in post-mining land includes changes in the physical, chemical and biological properties of the soil which result in a decrease in land productivity, changes in land landscape changes, the effective depth of the soil becomes shallow, and the formation of new layers of soil containing sand, gravel, remnants of tailings which will later form rock layers. One way to repair damaged post-mining land is by reclamation and conversion of post-mining land into agricultural land. The purpose of this study is to examine various post-mining reclamation lands that can be converted into agricultural land based on an analysis of soil fertility levels. The research method used is qualitative analysis and comparative analysis, namely by collecting, sorting and comparing data obtained from several journals and books (literature study). The results of the study show that some post-mining land can be converted into agricultural land, this depends on the location, the specific nature and characteristics of post-mining land, such as post-coal mining reclamation land with a fairly good level of soil fertility.
