Abstract

Utilization of land for other uses in Sigumpar District needs to be supported by information regarding land suitability. Therefore, an evaluation of the characteristics of the level of land suitability in the area was carried out, to analyze improvement efforts aimed at increasing productivity, as well as to create a map of actual land suitability and potential land suitability for durian plants in the district. The method used is the survey method. Land units are based on soil maps, slope maps, altitude maps, land cover maps, consisting of 6 land units and 18 points. The analysis method is the comparing (matching) method. The results of the research show that the level of land suitability for durian plants (Durio zibethinus Murr.) The actual land conditions suitable for durian cultivation in Sigumpar District are 1,856.22 ha. (2) Potential land conditions suitable for durian cultivation in Sigumpar District are 1,726.22 ha. Where limiting factors that cannot be remedied are temperature and soil texture, while limiting factors such as nutrient retention, nutrient availability, water availability and erosion hazards can be remedied in the form of: (1). Liming and fertilization adjusted to the results of soil tests on the land. Making drainage channels, planting parallel to contours, and making terraces. Keywords: land suitability evaluation, durian plant, utilizzation of other area, subdistrict of Sigumpar

Abstract

Peternakan Kambing Domba Arjuna di Desa Deli Tua, Sumatera Utara merupakan salah satu usaha yang dikembangkan masyarakat untuk untuk penyediaan kambing dan Domba sebagai pemenuhan permintaan kebutuhan  acara qurban, Akikah dan lain-lain di wilayah Sumatera Utara khususnya.  Limbah yang dihasilkan dari usaha ini adalah kotoran (inthil) yang mempunyai aroma yang tajam sehingga menimbulkan polusi udara.  Kegiatan pengabdian masyarakat ini bertujuan menambah wawasan peternak untuk mengelolah limbah dari kotoran ternaknya khususnya kambing menjadi produk yang dapat bermanfaat bagi kegiatan pertanian dan mengurangi polusi udara.  Pengelolaan inthil menjadi pupuk organik melalui proses pengomposan akan sangat membantu mengurangi bau yang tidak sedap dari limbah ternak kambing tersebut dan sekaligus menjadi produk yang dapat menambah pendapat petani.  Proses pembuatan pupuk organik inthil melalui proses fermentasi yang berguna mengurai unsur-unsur yang ada dalam inthil menjadi tersedia bagi tanaman.  Metode yang akan dilakukan dalam kegiatan pengabdian masyarakat ini berupa metode pendampingan (mentoring) dan metode partisipatory rural approach (PRA). Hasil kegiatan ini memberikan pemahaman dan kemampuan peternak dalam mengelola limbah ternak kambing dengan cara  pengomposan inthil sehingga anggota kelompok tani dapat menerapkannya.

Abstract

This research was conducted in Medan Marelan District, Medan City, North Sumatra. This research began in April 2024 until July 2024. The aim of this research was to determine the effect of administering several concentrations and methods of application of Paklobutrazol on the growth and production of beet plants. This research used a factorial randomized block design (RAK) consisting of two treatment factors, with the first factor being Paklobutrazol with the symbol (P) consisting of 3 treatment levels, namely: P0 = control, P1 = Paklobutrazol 0.5 grams/plant, P2 = Paclobutrazol 1 gram/plant. The second factor is the application method with the symbol (A) which consists of 2 levels, namely A1 = pour 100 ml of water/plant, A2 = sow. The parameters observed in this research were plant height (cm), number of leaves (strands), wet weight per plant (gr), tuber weight per plant (gr), and sugar content per plant (%). The results of the research showed that Paklobutrazol treatment had a very significant effect on plant height at 6 WAP and 7 WAP, wet weight per plant, tuber weight per plant. The application treatment had a very significant effect only on the tuber weight parameter per plant. The interaction of the two treatments had a very significant effect on plant height at 5 WAP, 6 WAP and 7 WAP, number of leaves at 5 WAP, 6 WAP and 7 WAP, fresh weight of plants, weight of tubers per plant, and sugar content per plant. The best treatment combination was in treatment P1A1 (Paklobutrazol 0.5 grams per plant) and (application method with cocor).
