Abstract

TITLE : VERTISOLS N-MINERAL DYNAMICS IN SEVERAL LITTER QUALITY COMBINATION AND N-SWEET MAIZE UPTAKE. Problems are often found on farms in humid tropics that lack of balancing between number and availability of nutrients. The imbalance will lead to nutrients leaching, especially NO3- to the bottom layer. NO3- is the result of oxidation of NH4+ through a process called nitrification, hence it is important to control over the process as it. The purpose of this study was to determine the effect of litter quality Trimmings (based on the content of polyphenols and lignin) to the dynamics of N-NH4+ and N-NO3- land. This study is a field experimental with basic use Completely Group Randomized Design. The first factor is addition of Chromolaena odorata litter which represent high quality (lignin content 4.27 %, 17.12 % polyphenols), Tectona grandis litter representing low quality (lignin content of 14.54, 11.92 % polyphenols), and litter mixtures (Chromolaena odorata+Tectona grandis). The second factor dose of 5 Mg/ha, 12.5 Mg/ha, 20 Mg/ha. Analysis of the data using the F test, if the results of analysis of variance is significant, it forward to Duncan Test at α level = 0.05. The results showed that the addition of various quality litter significantly ( P

Abstract

Anggur (Vitis vinifera) adalah salah satu buah paling populer di dunia, dan dapat dikonsumsi mentah atau diolah menjadi berbagai produk seperti jus atau selai. Anggur dapat tumbuh di berbagai jenis tanah, budidaya anggur harus memperhatikan faktor lingkungan utama yang mempengaruhi pertumbuhan serta perkembangan budidaya tanaman diantaranya adalah suhu, kelembaban tanah dan udara, intensitas cahaya serta status kesuburan tanahnya. Anggur merupakan tanaman merambat dengan sistem penanaman khusus, seperti menggunakan tiang atau kawat sebagai penyangga. Pengabdian masyarakat ini bertujuan untuk memberikan edukasi pada masyarakat cara mengembangkan kebun anggur dengan menerapkan teknologi modern IoT untuk membudidayakan anggur yang pada akhirnya dapat meningkatkan kemandirian keluarga. Metode yang digunakan dalam pengabdian ini adalah deskriptif. Pelaksanaan program pengabdian masyarakat ini dilakukan dalam beberapa tahapan, meliputi persiapan bahan dan materi, penyuluhan dan pengenalan, praktik/demplot budidaya anggur, penerapan IoT, pendampingan, seminar dan publikasi, pelaporan. Tahap persiapan melibatkan pencarian mitra, pengumpulan informasi tentang status mitra, dan merekomendasikan tindakan. Pelaksanaan melibatkan komunikasi dan pelatihan di lokasi mitra. Selain itu, pemantauan dan evaluasi berkala akan dilakukan untuk memantau perkembangan mitra pasca kegiatan. Melalui program pengabdian masyarakat ini, diharapkan minat masyarakat terhadap budidaya anggur akan meningkat, yang pada akhirnya berujung pada peningkatan kemandirian ekonomi. Adapun target luaran adalah sebagai berikut: publikasi pada jurnal nasional ber-ISSN yang dapat diakses secara online, publikasi pada media cetak / online, peningkatan daya saing perekonomian masyarakat dan penerapan iptek di masyarakat serta produk inovasi teknologi tepat guna yang dapat dimanfaatkan oleh masyarakat.

Abstract

The use of organic fertilizers and growth stimulants in the form of natural PGR is the main solution to support sustainable coffee cultivation. This research aims to determine the best treatment combination, the best dose of goat manure, and the best concentration of moringa leaf extract for vegetative growth of robusta coffee TBM 1. The research was conducted in Kemuning Village, Ngargoyoso District, Karanganyar Regency in October 2023-April 2024. The method used was a Randomized Complete Group Design (RCBD) consisting of two factors and three replications. The first factor was goat manure (0, 3, 4, and 5 kg.plant-1) . The second factor was moringa leaf extract (0, 150, 200, and 250 g.L-1concentration). Data analysis used analysis of variance (ANOVA) at the 5% error level then continued with Duncan's Multiple Range Test (DMRT) at the 5% error level if there were significant results. The observed variables include plant height, stem diameter, number of leaves, number of branches, leaf area, and total chlorophyll. The results showed that the application of goat manure and moringa leaf extract affected the vegetative growth of robusta coffee plants. The combination of goat manure 4 kg.plant-1and moringa leaf extract at a concentration of 250 g.L-1had an effect on increasing chlorophyll b and total chlorophyll. Goat manure had no effect on all variables. Without the moringa leaf extract had better effect on plant height and the moringa leaf extract concentration of 250 g.L-1affected the increase in leaf area 6 weeks after application.

Abstract

The demand for rice in Indonesia continues to increase but production has decreased. Efforts that can be made are the use of local varieties of mentik wangi rice. Mentik wangi rice has the disadvantages of long life, high stems, and low crop production. As a solution, plant breeding is carried out in the form of mutation by giving gamma irradiation which can improve unwanted genetic traits and produce superior varieties with the dose used of 200 gray. This study aims to evaluate the yield potential of promising mutant strains with 200 gray gamma irradiation on mentik wangi rice and get mutant strains that have superior criteria for short-stemmed, short-lived, and high-yielding. This research was conducted in the rice field of Ngampel Hamlet, Gentungan Village, Mojogedang, Karanganyar, Central Java. The research was conducted in June-October 2023. The design used was a Randomized Complete Group Design (RCBD) with a single factor, namely strains consisting of 14 mutant strains and 1 control strain with 3 repetitions. The results of observations were analyzed by Analysis of Variance (ANOVA) at the 5% level and continued with Duncan Multiple Range Test (DMRT) at the 5% level. All tested strains produced the expected superior criteria, namely short stem, short age, and high productivity.
