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

Evaluation of Soil Fertility for Horticultural Plantings in Land Recovery After the Eruption of Mount Sinabung. Karo Regency. North Sumatra is known as a center for Horticultural production (vegetables, fruits and ornamental plants) where the livelihoods of the population are primarily food crop and horticulture farming as well as mixed plantations. Karo Regency also has a volcano that is active again in Indonesia, namely Mount Sinabung. Mount Sinabung after approximately 10 years after the eruption, namely the eruption on August 27 2010, after the eruption of Mount Sinabung that volcanic material deposits within a certain period of time will experience weathering. This weathering will produce fertile soil that can be used for horticultural crops. Minerals contained in volcanic eruptions will decay and release various nutrients that are fertile for plant needs. The purpose of this study was to determine the parameters of soil fertility in horticultural cropping land in Karo District after approximately 10 years of the eruption of Mount Sinabung in increasing horticultural crop production and influencing agriculture in the future. The research was carried out from April to December 2023 in Karo Regency. Soil analysis activities were carried out at the Research and Development Center Laboratory of PT. Nusa Pusaka Kencana Analytical & Oc. Laboratory of Baringan Tebing Tinggi Gardens, North Sumatra. Soil analysis tests in the laboratory were carried out to determine the soil fertility parameter values for horticultural plantings after the eruption of Mount Sinabung. Urgency This research determines the evaluation of soil fertility in horticultural crops, in Karo District after the Mount Sinabung Eruption for land recovery and food security in North Sumatra and can identify horticultural land that requires a special strategy in its management and land management in post-eruption land recovery of Mount Sinabung. The results showed that the status of soil fertility in Tigapanah District was that the land was not affected by the eruption of Mount Sinabung, namely Moderate, with the limiting factors for soil fertility being CEC with the Low and Medium categories, and soil Potassium content with very low criteria. The status of soil fertility in Nemanteran District with the condition of the land affected by the eruption of Mount Sinabung is Moderate with the limiting factor for soil fertility being KB in the Low category, and soil Potassium content with very low criteria.

Abstract

The aims of this research are (1) to see the extent of the development contribution provided by the existence of Gundaling Farmstead integrated agrotourism in Lau Gumba Village, (2) What is the impact of Gundaling Farmstead integrated agrotourism on the socio-economics of the surrounding community. The research steps begin with an initial identification process, then data collection (interviews and questionnaires), tabulation, data analysis, until finally producing conclusions and report suggestions. The community population in Jaranguda Hamlet, Lau Gumba Village, is 459 people based on the initial survey. Determination of the sample in this research was by using simple random sampling. For sampling, the Arikunto formula was used so that the sample taken was 45 people. The analytical method used is descriptive analysis and t-test statistical analysis. The results of this research show that there are real differences in social and economic conditions before and after the existence of the Gundaling Farmstead integrated agrotourism in Lau Gumba Village, Berastagi District, Karo Regency with the results of the t test. Social criteria: t table = 2.014 while t count = 31.737, then t count > t table, so H1 is accepted and H0 is rejected. Economic criteria: t table = 2.014 while t count = 23.991, then t count > t table, so H1 is accepted and H0 is rejected. The existence of the Gundaling Farmstead Integrated Agrotourism in Lau Gumba Village is proven by the results of hypothesis testing showing that there have been changes in social and economic conditions that are better than before the existence of this agrotourism.

Abstract

Character is something that happens to humans created in their childhood home environment. Character, on the other hand, is something that everyone is born with. Character education, including character education in schools, can help shape good character. Character education can be achieved through the development of character values ​​in students. One of the traits that must be created from an early age is the character of love for the environment. The “green and clean” program is one of the techniques to create an atmosphere of loving the environment. The “green and clean” program seeks to encourage children to appreciate their environment from an early age and be able to take care of the beauty of the environment, starting in the school environment. The “green and clean” strategy is implemented in the classroom through a pre-learning program that invites children to participate in activities that cover aspects of K3 (Cleanliness, Beauty, Neatness). The curriculum involves combining picket lines in and around the school, as well as learning to care for plants in front of the class. This program can also increase and increase students' knowledge that a clean and attractive atmosphere can increase students' comfort in carrying out school activities, especially in learning programs. This Community Service Activity (PKM) will be held at SD 020254 Binjai City.

Abstract

Pengabdian ini bertujuan untuk mengedukasi masyarakat khususnya Kelompok tani yang berasa di Desa Lau Gumba untuk memanfaatkan limbah tomat menjadi pupuk organik cair. Kabupaten Karo sebagai penghasil tanaman tomat yang melimpah seringkali menimbulkan permasalahan bagi lingkungan diakibatkan dari hasil panen dan menimbulkan sisa tomat yang tidak terjual menjadi limbah yang tidak termanfaatkan dengan baik. Tomat merupakan buah musiman yang memiliki masa simpan tidak akan bertahan lama sekitaran 3 hari dan akan mengakibatkan pembusukan. Sehinggga perlu dicari solusi untuk pemanfaatan tomat sebelum terbuang perlu, salah satu upayanya yaitu dengan melakukan pengolahan tomat menjadi pupuk organik cair. Pupuk organik cair dapat digunakan untuk memperbaiki bahan organik tanah, memperbaiki dan meningkatkan kesuburan tanah serta mewujudkan pertanian yang bebas dari pupuk kimia untuk masyarakat di Desa Lau Gumba, Kecamatan Berastagi, Kabupaten Karo. Lokasi Pengabdian ini merupakan lokasi yang masyarakatnya mayoritas memiliki lahan budidaya tanaman hortikultura yang luas. Kegiatan pengabdian ini diharapkan masyarakat di lokasi pengabdian dapat mengembangkan kegiatan ini untuk membuat pupuk organik yang ramah lingkungan dan bebas dari bahan kimia.
