Abstract

Abstrak: Pengabdian kepada masyarakat mengenai pengenalan penyakit Ganoderma dan penggunaan jamur endofitik Hendersonia pada kelapa sawit bagi Masyarakat di Desa Gunung Ambat Kec. Sei Bingei telah dilaksanakan pada 29-30 Oktober 2019. Kegiatan tersebut bertujuan untuk meningkatan pengetahuan, keterampilan, dan awareness para petani mengenai penyakit Ganoderma dan tindakan pengendaliannya. Hari pertama diisi dengan prensentasi meteri dan diskusi indoor; dan hari berikutnya dilakukan praktek lapangan pengenalan penyakit Ganoderma dan penggunaan jamur Endofitik Hendersonia untuk pencegahan penularan penyakit tersebut pada tanaman kelapa sawit. Semua proses, pencapaian, dan lessons learn dari kegiatan ini dicatat dan didomentasikan dengan baik yang digunakan untuk penulisan jurnal ini. Untuk mengetahui adanya peningkatan pengetahuan dan keterampilan petani, dilakukan observasi pasca-pelatihan yaitu kemampuan pengenalan Ganoderma pada tanaman yang terinfeksi dan penggunaan jamur Hendersonia oleh petani. Data dan informasi yang diperoleh dianalisis secara deskriptif dan dinarasikan secara kualitatif.  Hasil yang ditemukan adalah terdapat 76 persen atau 38 orang yang telah memahami ciri-ciri tanaman yang terkena Ganoderma dan 100 persen peserta mampu mengaplikasikan Hendersonia pada bibit kelapa sawit dengan baik. Telah terjadi peningkatan pengetahuan dan keterampilan petani dalam hal pengendalian Ganoderma pada kelapa sawit. Pengetahuan dan keterampilan yang diperoleh kemudian dipraktekkan di lahan masing-masing pada proyek replanting yang dibiayai oleh pemerintah Indonesia. Abstract:  Community understanding of Ganoderma disease and using fungus of Hendersonia in oil palm’s farmers in Gunung Ambat Village, Sei Bingei Sub-district held on 29-30 October 2019. This project aims to increase the knowledge, skills and awareness of farmers about Ganoderma disease. The first day was material presentations and indoor discussions; and the following day a field practice was using Hendersonia Endophytic fungus to prevent transmission. All processes, achievements, and lessons learned from this activity recorded and well documented which used for writing this journal. To determine the increase in farmers' knowledge and skills, post-training observations been made, specifically the ability to detect Ganoderma to infected plants and the use of Hendersonia fungus by farmers. The data and information obtained analyzed descriptively and qualitatively narrated. The results found were 76 percent or 38 people understood the characteristics of plants affected by Ganoderma and 100 percent being able to apply Hendersonia to oil palm seeds well. There had been an increase in the knowledge and skills of farmers in controlling Ganoderma in oil palm. The knowledge and skills acquired been then practiced on their own fields in the replanting project financed by the government of Indonesia.

Abstract

Advanced knowledge of candlenut deshelling machine is needed to obtain optimal whole round kernel. The objective of this study was to modify the rotor bar on a candlenut deshelling machine with a ripple mill system. The method was engineering or modification, were made in the form of processes and products. The number of grooves on the rotor bar was modified became 2, 4 and 6. Rotation speed of the rotor bar were varied to 15 rpm, 18.75 and 25 rpm. The number of grooves gave a very significant effect on the capacity of the machine, whole round kernel, broken kernel, sticky kernel and unbroken seeds. The rotational speed of the rotor bar gave a very significant effect on the capacity of the machine, broken kernel, and sticky kernel, and gave an insignificant effect on whole round kernel and broken kernel. Interaction between the number of grooves and the rotational speed of the rotor bar gave a very significant effect on the capacity of the machine and the sticky kernel and insignificant effect on the whole round kernel, crushed kernel and unbroken seeds.

Abstract

Guava is one of the fruits that easily rot after postharvest. With the nature of guava that is easy to rot, it is necessary to find a way to maintain the quality of guava by extending its shelf life and freshness. The purpose of this study was to determine the effect of hot water treatment on the control of anthracnose in guava, to determine the effect of beeswax treatment on the control of anthracnose in guava and to determine the effect of hot water treatment with beeswax to maintain the quality of guava fruit. The experimental design used in this study was a completely randomized design using 5 treatments. The first treatment was control treatment, that is, without any treatment. The second treatment used a concentration of 4% beeswax and 5 minutes of hot water immersion. The third treatment was using a concentration of 4% beeswax and 10 minutes of hot water immersion. The fourth treatment was using a concentration of 6% beeswax with 5 minutes of hot water immersion. The fifth treatment was using a concentration of 6% beeswax and 10 minutes of soaking. The treatment was repeated three times. The results of this study showed that the best treatment in inhibiting anthracnose on guava fruit was with a concentration of 6% beeswax and 10 minutes of immersion with 30% of disease attack.

Abstract

Pertumbuhan ekonomi setiap wilayah berbeda dengan wilayah lainnya. Oleh karena itu, perencanaan pembangunan ekonomi suatu wilayah harus memperhatikan aspek ekonomi, sosial, dan fisik wilayah tersebut, serta hubungannya dengan wilayah lain. Hal ini sangat penting bagi pembangunan ekonomi yang mengacu pada sektor unggulan, selain berpengaruh pada percepatan pertumbuhan ekonomi, juga akan mempengaruhi perubahan mendasar dalam struktur perekonomian daerah, untuk menciptakan pertumbuhan ekonomi dilihat dari perkembangan PDRB. Tujuan penelitian ini adalah untuk mengetahui pengaruh jumlah penduduk, luas lahan, produksi, dan pendapatan daerah terhadap PDRB subsektor tanaman pangan di Provinsi Sumatera Utara. Dari November hingga Desember 2021, penelitian dilakukan di Provinsi Sumatera Utara. Alat analisis yang digunakan adalah fungsi Cobb-Douglas. Hasil penelitian menunjukkan bahwa secara simultan (Uji F) variabel jumlah penduduk, luas lahan, produksi dan pendapatan daerah berpengaruh signifikan terhadap PDRB subsektor tanaman pangan di Provinsi Sumatera Utara. Variabel jumlah penduduk, produksi, dan pendapatan daerah berpengaruh signifikan secara parsial (uji t) terhadap PDRB subsektor tanaman pangan di Provinsi Sumatera Utara, namun luas lahan tidak berpengaruh signifikan terhadap PDRB subsektor tanaman pangan di Provinsi Sumatera Utara.

Abstract

Corn (zea mays) is one of the potential food crops aimed at improving the national economy. The increase made in corn production through the suppression of corn imports by the government so that the land for corn development can be utilized. Karo Regency is a corn production center in North Sumatra that has the potential to develop corn farming with a land area of 107,241 ha with a production of 715,940 tons. The purpose of this study was to analyze the corn farming development strategy and the internal and external constraints faced in corn farming activities. The research method used is descriptive method and data collection techniques are carried out using observation, interviews and questionnaires. There are two sub-districts as samples, namely Simpang Empat and Barusjahe Districts. The analysis technique used is descriptive and SWOT analysis. The results of the study indicate that the development strategies that can be carried out in corn farming in Karo Regency are (a) increasing the bargaining power of farmers in the context of industry/traders that impose strict quality requirements; (b) increase productivity to prepare for competition from imported corn products; (c) planning for weather variations to improve the quality of corn produced by farmers; (d) increase the knowledge and capacity of farmers in the context of controlling pests and diseases in maize; (e) reduce corn production costs to reduce fluctuations in production, quality, and price
