Abstract

Nursery is the beginning of the process to reach optimum production, so proper treatment is necessary. To reduce side effects on the environment and higher fertilizing costs, we employ mycorrhyza that is expected to increase efficiency and effectiveness of the production process. The purpose of this research is to understand the effects of mycorrhyza application on the vegetative growth of palm oil at the main nursery. This research is using non-factorial Randomized Completely Block Design with 4 (four) treatments and six repetitions that used 24 samples by observing the growth of the tree trunk, its diameter, and number of leaves. The last observation was conducted to know the degree of mycorrhyza infection in every treatment. The results showed that mycorrhyza application had no significant effect on the growth of the plant and trunk diameter, but it has very significant effect on the growth of the leaves at the last week. The more significant result was observed at M3 with 75 gram dosage. The infection degree at the end of the research showed a very significant effect with average value of 6.00 at M3 compared to M1 with 4.00 value. Keywords: mycorrhyzae, oil palm, main mursery

Abstract

Perkembangan teknologi informasi yang pesat di era digital menjadi tantangan serius bagi generasi muda, terutama terkait masifnya penyebaran hoaks dan ancaman baru seperti deepfake. Permasalahan ini juga ditemukan di lingkungan SMKN 7 Pekanbaru, sebuah sekolah kejuruan berbasis teknologi, di mana para siswanya menunjukkan tingkat literasi digital yang rendah. Observasi awal mengidentifikasi minimnya pemahaman siswa terhadap teknologi deepfake serta rendahnya keterampilan dalam menggunakan alat verifikasi informasi yang kredibel. Menjawab tantangan tersebut, dilaksanakan kegiatan pengabdian kepada masyarakat berupa pelatihan teknis dengan dua fokus utama. Pertama, melatih siswa untuk mengenali dan menganalisis konten deepfake. Kedua, memberikan keterampilan praktis dalam menggunakan Google Fact Check Explorer untuk memeriksa kebenaran berita. Metode pelatihan dilakukan secara langsung di laboratorium komputer untuk memastikan penguasaan keterampilan. Hasilnya, kegiatan ini berhasil meningkatkan kesadaran dan pemahaman siswa terhadap manipulasi digital, serta membekali mereka dengan kemampuan verifikasi informasi secara mandiri. Pelatihan ini secara efektif berkontribusi pada penguatan kompetensi literasi digital, membentuk siswa menjadi pengguna teknologi yang lebih kritis, cerdas, dan bertanggung jawab

Abstract

Land utilization in immature palm oil is very helpful for oil palm farmers to get a source of income when their palm oil crops is still immature. In addition, these intercrops can also be used as ground cover plants, which can prevent erosion and evaporation of the soil. The research was conducted in the experimental garden of the Institut Teknologi Sawit Indonesia (ITSI). The research time was 3 months. The purpose of this research is to determine the feasibility study of soybean business as an intercrop in immature crop land whether or not this soybean crop is profitable. If it is profitable then farmers can receive income from this soybean intercrop before the palm oil plants can be harvested. The results of the research conducted are the production of soybean crops on immature palm oil land with a distance of 20 cm x 20 cm on 2 beds with a bed size of 4 m x 1 m is 10 kg. The total production cost of soybean intercrops in immature palm oil is Rp.86,861. Income on soybean crops in immature palm oil is Rp.130,000. The profit on soybean intercrops in immature oil palm is Rp.43,139. Soybean crops (Grobogan variety) in immature palm oil are financially and economically feasible, with an R/C value > 1, so the farming business is profitable. Break Event Point of soybean intercrops at immature oil palm, BEP production 6.68 kg BEP price Rp.8,686.
