Abstract

Abstrak : Pelaksanaan Pengabdian kepada masyarakat dilakukan untuk menjawab masalah petani dalam teknik budidaya padi lokal “Banga Laka” yang terindikasi menggunakan pestisida sintetik berlebih, selain itu petani tidak mengenal jenis hama yang menyerang tanaman padi sehingga cenderung penggunaan pestisida tidak tepat sasaran. Solusi yang ditawarkan oleh tim PKM yaitu menerapkan teknologi light trap yang terbukti efektif mengendalikan hama pada tanaman padi. Metode yang digunakan pada kegiatan ini adalah 1) penyuluhan berkenaan dengan pengenalan dan perawatan alat light trap dan 2) pengamatan langsung dilapangan untuk melihat jenis-jenis hama yang terperangkap pada light trap. Evaluasi efektivitas light trap dilakukan dengan metode partisipatif dimana masyarakat ikut melakukan pemantauan hama yang terperangkap pada setiap jenis perangkap dan melakukan perhitungan penghematan biaya produksi. Pemasangan light trap selama satu bulan dapat menekan penggunaan jenis pestisida sebesar 83,86% dengan penghematan biaya pengendalian hama sebesar Rp. 1.325.000/musim tanam, berdasarkan pengamatan diketahui bahwa light trap berhasil menangkap 7 jenis hama (881 ekor) dengan proporsi tertinggi pada jenis cahaya ungu (49%).Abstract: The implementation of community service is carried out to answer farmers' problems in the local rice cultivation technique "Banga Laka" which is indicated to use excess synthetic pesticides, besides that farmers do not know the types of pests that attack rice plants so that they tend to use pesticides not on target. The solution offered by the PKM team is to apply light trap technology which is proven to be effective in controlling pests on rice plants. The methods used in this activity are 1) counseling regarding the introduction and maintenance of light traps and 2) direct observation in the field to see the types of pests trapped in light traps. Evaluation of the effectiveness of light traps is carried out using a participatory method where the community participates in monitoring pests trapped in each type of trap and calculating production cost savings. Installing a light trap for one month can reduce the use of pesticides by 83.86% with a pest control cost savings of Rp. 1.325.000/planting season, based on observations it was known that the light trap managed to catch 7 types of pests (881 individuals) with the highest proportion in the type of purple light (49%).

Abstract

Counseling of Soil Fertility, Organic Fertilizers, Pests and Plant Diseases for Baranuri Farmers Group. The Baranuri Farmers Group (KT. Baranuri) is one of the providers of vegetables for the people of Ende City. The results of interviews with farmers obtained several problems, namely, there is no data on soil fertility and lack of understanding of soil fertility, organic fertilizers, pests and plant diseases. The solution given is to analyze soil pH and organic-C to be used as a reference for soil fertility conditions as well as counseling about soil fertility, organic fertilizers, pests and plant diseases. This service activity aims to provide information on soil fertility, increase farmers' knowledge regarding soil fertility, organic fertilizers and plant pests and diseases. The counseling method used is a group approach. Purposive soil sampling, samples were taken diagonally. The organic-C content was analyzed in the laboratory by Walkley and Black method, while soil pH was measured directly on the field using 4 in 1 Soil Survey Instrument and then matching with the criteria of assessment of soil analysis results by the Indonesian Soil Research Institute. The results obtained were the soil pH was 4-5 (very acidic-acidic) and soil organic C was 2.03-2.37% (moderate). The extension activities were succeeded in increasing public knowledge from 46.7% to 86.7% (an increase of 85.7%). The recommendation from this activity is to create a demonstration field to apply an organic fertilizer that can be observed directly by farmer groups.

Abstract

Preparation and characterization of Fe3O4 magnetized natural zeolite adsorbent for adsorption of methylene blue dye have been carried out. Natural zeolite/Fe3O4 adsorbent preparation was carried out using coprecipitation of Fe2+ and Fe3+ ions (1: 2 mol ratio) on the natural zeolite surface. Characterization was carried out using X-Ray Diffraction (XRD), Fourier Transform Infra-Red (FTIR), and Scanning Electron Microscopy (SEM) to determine the effect of Fe3O4 on the natural zeolite surface. UV-Vis spectroscopy was used to determine the concentration of methylene blue after the adsorption process. The characterization results showed that Fe3O4 was successfully embedded in the natural zeolite without damaging the natural zeolite's crystallinity. Natural zeolite/Fe3O4 adsorbent showed easy separation from water medium after the adsorption process. The optimum conditions for adsorption were achieved at the contact time of 60 minutes, and the initial concentration of methylene blue was 30 ppm with an adsorbent mass of 25 mg. Adsorption kinetics followed pseudo-second-order reaction kinetics, and adsorption isotherm followed Langmuir isotherm with an adsorption capacity of 32.258 mg/g.

Abstract

Penelitian ini dilakukan untuk mengetahui konsentrasi logam berat Pb di kebun hortikultura Kelurahan Rewarangga Selatan. Kontaminasi logam berat Pb diakibatkan oleh penggunaan pupuk fosfat secara terus menerus dan juga logam berat Pb berasal dari limbah domestik yang masuk melalui air irigasi. Logam berat Pb diekstraksi menggunakan metode destruksi basa dan hasil analisis dengan spektrofotometer serapan atom menunjukan konsentrasi Pb sebesar 52 ppm. Hasil analisi sifat kimia tanah menujukkan pH tanah bersifat netral dengan nilai pH 6,2-6,8. Nilai kapasitas tukar kation cukup tinggi yaitu sebesar 65,6 Meq/100g yang menunjukkan tingkat kesuburan tanah yang masih bagus. C-Organik juga menunjukan nilai yang tinggi yaitu sebesar 3,67 %. Hal ini  mengindikasikan banyaknya senyawa organik seperti asam humat dan asam fulfat yang dapat membentuk senyawa kompleks dengan logam berat Pb. Dari hasil analisis sifat kimia tanah diprediksikan bahwa logam berat Pb sulit teradsorpsi oleh tanaman, karena kondisi lingkungan yang tidak memungkinkan logam berat Pb berada dalam bentuk ion Pb2+ yang mudah diserap oleh tanaman.

Abstract

Since ancient times, woven fabric craftsmen in the Ende area have used tarum leaves as a dye in their woven fabrics. Extraction of color pigments in tarum leaves is carried out by soaking in water or seawater for a certain length of time so as to produce quality color pigments.This study aims to determine the stability of natural dyes in tarum leaves which are used as dyes for woven fabrics in the Ende area of ​​East Nusa Tenggara which were extracted using water and seawater as solvents. The research was carried out in the laboratory of the Faculty of Agriculture, University of Flores using the experimental method. The results showed that tarum leaves produced the optimum wavelength when soaked for 24 hours and there was a decrease in the color stability of the tarum leaf extract due to storage factors, increased temperature, duration of sunlight and increased concentrations of oxidizing agents.
