Abstract

Research on the Effect of the Use of Organic Cow Manure and KCL on the Growth and Production of Shallots (Allium Ascalonicum L.) has been carried out in May-August 2021 at UPT. Parent Seeds of Kutagadung Berastagi Horticulture. The aim of the study was to determine the effect of the right combination of cow dung and KCL fertilizer on the growth and production of the Batu ijo variety of shallots. The results showed that the effect of KCL fertilizer on plant height was that K0 (19.97 cm) was significantly different from K1 (22.35 cm), K2 (27.35 cm), and K3 (30.41 cm), and the effect of cow manure O0 (21.97 cm) was significantly different from O2 (25.52 cm) and O3 (27.89 cm) but not significantly different from O1 (23.7 cm). The average leaf growth at 8 WAP with the effect of K level was K0 (26.75 cm), K1 (17.17 cm), K2 (27.08 cm), and K3 (26.75 cm). Meanwhile, the influence of the O factor is O0 (26.33 cm), O1 (27.08 cm), O2 (27.25 cm), and O3 (27.08 cm). Onion crop production per sample had the effect of K0 level (88.7 g), significantly different from K1 (106.2 g), K2 (125.5 g), and K3 (137.1 g) and the effect of cow manure O0 ( 106.9 g) was significantly different from O1 (112.7 g), O2 (115.5 g), and O3 (122.3 g). The number of tubers affected by KCL fertilizer was K0 (8.6) significantly different from K1 (10.2), K2 (14.2), and K3 (15.04), and the effect of cow manure O0 (9) was significantly different from O1 (11,2), O2 (13,6), and O3 (14,2). Onion bulb diameter was significantly different from KCL K0 (1.46 cm) fertilizer with K1 (1.96 cm), K2 (2.66 cm), and K3 (3.24 cm), and the effect of cow manure O0 (2, 01 cm ) was significantly different from O1 (2.21 cm), O2 (2.41 cm), and O3 (2.69 cm). Wet weight of tubers per plot of KCL K0 (1.07 kg) was significantly different from K1 (1.33 kg), K2 (1.83 kg), and K3 (2.18 kg), and the effect of cow manure O0 (1 .04 kg) was significantly different from O1 (1.49 kg), O2 (1.88 kg), and O3 (2 kg).

Abstract

Penelitian okupasi Hendersonia kepala sawit di pembibitan dan pasca-penanaman telah dilakukan di PTPN III Kebun Pulau Mandi dan Kebun Tanah Raja, Maret 2018-Januari 2020. Umur bibit 3 bulan digunakan GanoEF 50 gr/ pokok, umur bibit 6 bulan GanoEF 50 gr/ pokok, dan umur bibit 9 bulan GanoEF 50 gr/ pokok. Untuk tanaman di lapangan, Kontrol/ perlakuan I: kontrol, Perlakuan II: Bibit yang tidak menggunakan GanoEF saat pembibitan dan diberikan GanoEF sebanyak 500 gr di lubang tanam saat penananaman, Perlakuan III: Bibit yang telah diberikan 100 gr GanoEF saat dipembibitan dan diberikan GanoEF sebanyak 500 gr di lubang tanamsaat penanaman, dan Perlakuan IV: Bibit yang telah diberikan 150 gr GanoEF saat dipembibitan dan diberikan GanoEF sebanyak 500 gr di lubang tanam saat penanaman. Data dianalisis secara deskriptif yaitu dengan menghitung persentase jumlah potongan akar ditemukannya Hendersonia berbanding seluruh potongan akar yang diamati dikali 100%. Hasil penelitian ini menunjukkan, rata-rata okupasi Hendersonia di pembibitan setelah dua kali aplikasi (100 gr/ bibit) sebesar 36,7% dan setelah tiga kali aplikasi (150 gr/ bibit) adalah 70%. Hasil percobaan terhadap tanaman yang sama setelah tiga bulan ditanam di lapangan ditemukan adanya okupasi Hendersonia sebesar 57,32% untuk tanaman yang diberikan Hendesonia di lubang tanam (perlakuan II), 68% Hendersonia pada perlakuan III, dan 74,76% Hendersonia ditemukan pada perlakuan IV. Setelah tanaman berumur satu tahun di lapangan dilakukan pemeriksaan kembali kandungan Hendersonia di dalam akar dan ditemukan, terdapat 0% pada perlakuan I, 69,28% pada perlakuan II, 73,32%  perlakuan III, dan 77,3% pada perlakuan IV

Abstract

Research has been carried out using Mabar Compost and NPK Yara Mila 16:16;16 on lettuce (Lactuca Sativa L.). The aim of the study was to determine the effect of Mabar Compost Fertilizer, the effect of NPK Yara Mila 16:16:16, and the effect of the interaction between the two types of fertilizer on the growth and yield of lettuce plants. The study used a factorial randomized block design consisting of two factors. Factor I: Dosage of Mabar Compost with the symbol "K", namely K0: 0 Control (without treatment), K1: 350 grams/plot, K2: 550 grams/plot, and K3: 750 grams/plot. Factor II: Dosage of NPK fertilizer with the symbol "P", namely P0: 0 Control (without treatment), P1: 18 grams/plot, P2: 24 grams/plot, P3: 30 grams/plot. The results showed that Mabar Compost Fertilizer and NPK Fertilizer had no significant effect on the height and number of leaves of lettuce plants. Mabar Compost Fertilizer had a significant effect on the yield weight of fresh lettuce plants. The average yield weight of plants affected by compost was K0 (109.4 gr), not significantly different from K1 (120.2gr) but significantly different from K2 (125.4 gr) and K3 (165.2 gr). No interaction was found between the type of fertilizer and the dose of fertilizer on the research parameters.

Abstract

Research on the effect of plant spacing and weeding time on the growth and production of carrots (Daucus carota L) has been well carried out in February-May 2021 at UPT. Kutagadung Horticulture Parent Seeds. Berastagi District, Karo Regency, North Sumatra. The aim of the study was to determine the effect of spacing and weeding time on the growth and yield of carrots. The results showed that the average plant height affected by the distance between J1 18.5 cm and J2 16.4 cm and J3 15.2. cm and the average height of the influence of weeding, namely M0 (17 cm) was significantly different from M1 (16.5 cm), M2 (16.6 cm), and M4 (16.5 cm). The effect of spacing (J) on tuber length showed that J1 (17.51 cm) was significantly different from J2 (18.22 cm) and J3 (18.23 cm). The effect of spacing (J) treatment on tuber diameter showed that J1 (3.36 cm) was significantly different from J2 (3.79 cm), and significantly different from J3 (5.27 cm), the effect of weeding time (M0) 3, 52 cm was significantly different from M1 (4.14 cm), M2 (4.25 cm), M3 (4.34 cm), and M4 (4.47 cm), and the combination treatment J1M0 resulted in the smallest tuber size of 3.1 cm. and the largest in J3M4 is 5.75 cm. The combination of J3M4 produced the highest tuber diameter of 5.75 cm which was the optimum treatment. The effect of plant spacing on tuber weight per sample was found that J1 (86.47 gr) was significantly different from J2 (101.82 gr) and J3 (186.48 gr), the effect of the weeding time factor M0 (70.24 gr) was significantly different from M1 (135.41 gr), M2 (137 gr), M3 (137.88), and M4 (144.08 gr)

Abstract

Pestisida nabati yang dibuat dari daun papaya memiliki karakteristik yang mudah terurai di lingkungan, umumnya cukup aman terhadap makhluk bukan sasaran termasuk musuh alami hama dapat dipadukan dengan komponen lain PHT, tidak cepat menimbulkan resistensi, komponen ekstrak bisa bersifat sinergis, dan beberapa jenis dapat disiapkan sendiri oleh masyarakat. Kegiatan pengabdian bertujuan memberikan pengetahuan dan keterampilan kepada mitra yaitu Ibu ibu PKK Desa Perumnas Simalingkar agar dapat memanfaatkan pestisida nabati dalam mengendalikan hama tanaman di pekarangannya. Hal ini karena pestisida nabati memiliki kelebihan lebih aman untuk lingkungan dan dapat dibuat dari tumbuhan di sekitar. Kegiatan pengabdian kepada masyarakat berjalan dengan baik dengan diikuti 56 orang masyarakat Desa Perumnas Simalingkar, 10 orang dosen dari Universitas Quality, 1 orang dosen dari Universitas Quality berastagi, dan 5 orang mahasiswa dari Universitas Quality. Ibu-ibu PKK Desa Perumnas Simalingka merupakan bagian dari masyarakat sangat antusias dalam mendengarkan pemaparan dari tim pengabdian ditambah dengan adanya kegiatan penyuluhan “Pembuatan Pestisida Nabati”.
