Abstract

This study was conducted to analyze the effect of composting from oil palm fronds and soil type variations, as well as the interaction of these two factors on the development of oil palm seedlings at the main nursery stage at the Education and Research Garden (KP2) Instiper, Wedomartani Village, Sleman, Yogyakarta. The research method uses a factorial design with two factors arranged in a Complete Random Design (RAL), where the first factor is the dose of palm frond compost consisting of four levels, namely 0 grams as a control, 100 grams, 200 grams, and 300 grams, while the second factor includes three types of soil with different characteristics, namely regosol, latosol, and grumusol. Data analysis was carried out using ANOVA for treatments that showed significant differences. Based on the results of the analysis carried out, there was no significant interaction between the application of oil palm frond compost and soil type on the growth of seedlings in the main nursery, but separately it was found that the application of the highest dose of compost of 300 grams per polybag had a real effect on the growth of oil palm seedlings, while on the other hand, the use of latosol type soil showed a significant positive effect. Especially on the dry weight parameter of oil palm seedlings at the main nursery stage, which indicates that these two factors independently have an important role in optimizing the growth of oil palm seedlings

Abstract

Literature research has been carried out on the use of fertilizer on oil palm plants with several types of fertilizer. The aim of this research is to see the effect of several types of fertilizer on palm oil yields. The method used in this research is a literature review. Research results show that the fertilizers often used are chicken manure, goat manure, compost and cow urine. Providing animal manure fertilizer at doses of 0, 50, and 100 g/polybag had the same effect on the development of the upper seedlings, while a dose of 50 g/polybag had the best effect on the development of the lower seedlings. Fertilizer greatly influences the level of soil fertility, thereby increasing the number of leaves, the health of palm stems and palm harvest yields.

Abstract

Weeds are nuisance plants that compete with the main crop, namely oil palm plants, in absorbing nutrients. If not controlled, the presence of weeds can cause a decrease in oil palm plant productivity. Inventory of dominant weeds in the highlands facilitates weed control at an altitude of 600-1000 meters above sea level (MDPL). The study was conducted at PT. Perkebunan Nusantara IV Kebun Bah Birung Ulu in Afdeling I, the research time started in February to March 2025. This study used a quantitative descriptive method with a direct weed identification method. The weed identification study in the highlands was at an altitude of 950 masl. The parameters observed were weed grouping, obtaining the Summed Dominance Ratio and the Important Value Index. From the results of the observations, it can be concluded that there are 12 types of weeds with the highest INP of 87%, namely Murdannia Nudiflora. The Summed Dominance Ratio analysis shows that Murdannia nudiflora has the highest dominance, while Spermacoce Ocymifolia has the lowest dominance.

Abstract

Kelapa sawit merupakan tanaman monoecious yang memiliki bunga betina dan bunga jantan yang terdapat pada satu pohon. Biasanya perkawinan silang terjadi dengan bantuan agen polinasi (Elaeidobius kamerunicus) untuk menghasilkan tandan buah kelapa sawit. Fenologi merupakan ilmu yang mempelajari fase-fase alami pada tanaman. Fenologi pembungaan merupakan jenis tanaman yang menjadi karakter penting dalam siklus hidup tanaman untuk berkembang biak. Pengamatan siklus perkembangan bunga hingga buah dapat menjadi acuan saat panen dan diperlukan untuk mengatasi permasalahan terkait rendahnya produksi buah. Penelitian dilaksanakan di kebun praktik Institut Teknologi Kelapa Sawit Indonesia (ITSI) Medan. Waktu penelitian dimulai dari bulan September 2021 sampai dengan Maret 2022. Penelitian ini bertujuan untuk mengetahui dan mengkaji bagaimana tahapan pembungaan tanaman kelapa sawit pada dua varietas yang berbeda sebagai perkembangan bahan tanaman kelapa sawit dengan karakteristik pembungaan yang berbeda pada dua varietas yang berbeda. Metode yang digunakan adalah deskriptif dengan model kualitatif dan kuantitatif. Hasil penelitian menunjukkan bahwa penggunaan varietas yang berbeda memberikan hasil perkembangan yang berbeda terhadap pertumbuhan generatif dan vegetatif tanaman kelapa sawit. Fase pertumbuhan generatif dan vegetatif sangat dipengaruhi oleh bibit unggul yang digunakan. Pengamatan vegetatif dilakukan sebagai penunjang perkembangan tanaman kelapa sawit. Hasil uji T-Test menunjukkan bahwa nisbah kelamin, tinggi tanaman, jumlah helaian daun, panjang rachis, tebal tangkai daun, penampang melintang tangkai daun (PxL), jumlah anak daun sepihak, lebar anak daun, luas daun dan luas daun total berpengaruh terhadap penerimaan H0 (perbedaan tidak nyata) sedangkan uji T-Test pada keliling batang, lebar tangkai daun dan panjang anak daun memberikan pengaruh menolak H0 (berbeda nyata)

Abstract

The growing interest in urban farming has led to an increased use of non-soil planting media. With land becoming increasingly scarce and expensive, alternative media are being explored for plant cultivation. In parallel, urban waste, particularly styrofoam waste, has emerged as a major issue that demands effective solutions. This paper reports on a continuation of our previous research concerning the development of growing media using styrofoam fibers. Styrofoam waste was collected, cleaned, and processed into fibers using a Rotary Forcespinning apparatus. The resulting fibers were white, durable, long, and had an average diameter of 8 mm. The fibers formed clumps with inter-fiber porosity, and when accumulated in volume, they could be applied as a non-soil planting medium. To be considered a viable planting medium, the styrofoam fiber must be evaluated across several performance parameters, one of which is wettability. Results showed that the water absorption performance of styrofoam fiber was lower compared to that of rockwool and PET fiber media. Future research will focus on improving the water absorption capacity of the styrofoam fiber

Abstract

Tandan kosong umumnya dimanfaatkan sebagai pembenah tanah, disisi lain potensi tandan kosong kelapa sawit dapat dimanfaatkan menjadi berbagai produk yang memiliki nilai ekonomi yang tinggi. Limbah dapur berupa nasi, buah dan sayur banyak ditemukan di tempat pembuangan sampah yang berasal dari pemukiman maupun pasar. Limbah tersebut diklaim sebagai salah satu sumber gas rumah kaca. Penelitian bertujuan untuk mengetahui potensi tandan kosong kelapa sawit dan limbah dapur sebagai pakan maggot pada tiap fase perkembangbiakannya. Penelitian dilakukan di Basmallah BSF Farm Kabupaten Deli Serdang, menggunakan rancangan acak lengkap faktorial, dengan dua faktor perlakuan yaitu tandan kosong kelapa sawit yang disusun tiga taraf (tandan kosong utuh, tandan kosong dipotong menjadi empat bagian, tandan kosong yang telah dicacah) dan faktor limbah dapur dengan dua taraf (tanpa limbah dapur, menggunakan limbah dapur), masing-masing 3 ulangan. Hasil pengujian parameter disusun pada daftar sidik ragam dan hasil yang berbeda nyata diuji dengan DMRT taraf 5%. Hasil penelitian menunjukkan baby maggot tidak dapat hidup pada pakan kering seperti pada tandan kosong tanpa bahan tambahan yang lembab. Tandan kosong utuh yang dicampur dengan limbah dapur sangat berpotensi dijadikan sebagai pakan baby maggot. Massa maggot, pra pupa, pupa dan lalat dewasa yang dihasilkan lebih besar pada pakan campuran tandan kosong utuh dan limbah dapur dibanding perlakuan lainnya. Semakin besar massa maggot, semakin besar kemampuan maggot mengkonversi pakan menjadi bahan organik
