Abstract

Seedlings which look prima is a prerequisite for the success of oil palm cultivation. Besides, because of the factors in the pre-nursery genetic, the provision of nutrients in early growth seedlings has an important role performance determine the appearance of the seedlings thoroughly. This study aims to determine the influence of the growth of oil palm seedlings at each concentration of organic fertilizer tithonia and fertilizer of urea for pre-nursery. The experiment was carried out from Oktober 2023 to April 2024 in the Experimental Garden of the Faculty of Science and Technology, the University of Labuhanbatu Rantauprapat with a height of 13 meters above sea level. The experimental design used was a Randomized Block Design with a factorial pattern that is repeated three times. The experimental design used was a Randomized Block Design with a factorial pattern that is repeated three times. The first factor includes the dose of Organic Fertilizer Tithonia (ton/ha) comprising of three standards, namely T0 = 0 ton/ha, T1 = 10 ton/ha, T2 = 20 tons/ha and the second factor was fertilizer dosage Uera which consists of four levels, namely U0 = 0 kg/ha, U1 = 100 kg/ha, T2 = 200 kg/ha, U3 = 300 kg/ha. The experimental results show that there are significant interactions of organic fertilizer Tithonia with fertilizers urea on plant height (cm) and leaf area of oil palm seedlings (cm2). Treatment of organic fertilizer tithonia 20 tons/ha with fertilizer urea 300 kg/ha yield plant height and leaf area of oil palm seedlings the best for pre-nursery.

Abstract

Gunung Leuser National Park (GLNP) is one of Indonesia's most important conservation areas. Around GLNP, there are a group manages bamboo forests in Pamah Simelir Hamlet. This activity aims to carry out outreach activities to increase the institutional capacity of sustainable bamboo communities to support the management of GLNP buffer areas in mitigating climate change. The activity methods include lecture methods, group discussions, brainstorming, role-playing, collective problem-solving, questionnaires and interviews with groups, and Focus Group Discussions (FGD). The results of the training activities showed that the group's technical skills had improved, especially in managing bamboo forests as part of conservation and climate change mitigation efforts. They can apply the techniques taught, such as planting and maintaining bamboo in a sustainable manner, as well as using bamboo as a raw material with economic value. Increasing these skills can reduce pressure on forest areas and improve the welfare of local communities. The training carried out has succeeded in positively boosting the institutional capacity of the Bambu Lestari Community, both in technical, managerial, and collaboration aspects. This activity can become a reference for local governments and stakeholders in adopting an inclusive and sustainability-oriented approach while involving local communities as partners in preserving the environment and facing the challenges of climate change.

Abstract

Oryctes rhinoceros L. merupakan salah satu hama penting pada tanaman kelapa sawit. Hama ini dapat menyebabkan turunnya produksi tandan buah segar (TBS) pada tahun pertama hingga 69%, bahkan sampai menyebabkan 25% tanaman muda mati. Tujuan dari penelitian ini adalah untuk mengetahui pemanfaatan sari buah nanas dan air aren sebagai perangkap alernatif dalam mengendalikan hama kumbang tanduk. Penelitian dilaksanakan dilaksanakan pada bulan Januari 2022 di Perkebunan kelapa sawit LTJ , Kecamatan Tanjung Medan, Kabupaten Rokan Hilir, Provinsi Riau. Perlakuan memiliki 3 perlakuan dengan masing-masing perlakuan diulang sebanyak 10 kali, perlakuan yang di uji, (a) perangkap dengan No = 500 gram buah nanas. (b) N1 = 500 gram buah nanas + 1 liter air nira, (c) N2 = 1 kg buah nanas + 2 liter air nira.Selanjutnya digantungkan pada tiang kayu/bambu dengan tinggi 2,5 m, dengan jarak antar perangkap 25 meter, Masing-masing perangkap diturunkan setiap pagi hari selama 7 hari pengamatan. Hasil penelitian menunjukkan kumbang tanduk tertangkap paling tinggi yaitu pada pemberian perlakuan N2 sebanyak 46 ekor dengan rataan 6,5 ekor/ hari dan paling rendah pada perlakuan No yaitu sebanyak 19 ekor dengan rataan 2,7 ekor/hari. Persentase jenis kelamin kumbang tanduk yang tertangkap paling tinggi adalah berjenis kelamin jantan yaitu sebesar 62,5%, dan jenis kelamin betina sebesar 37,5%. Dengan demikian, pemanfaatan sari buah nanas dan air nira dapat dijadikan sebagai perangkap ferotrap alternatif untuk mengendalikan hama kumbang tanduk.

Abstract

Oil palm (Elaeis guineensis Jacq.) is one of Indonesia's leading plantation commodities and plays a strategic role in the national economy. The purpose of this study was to determine the effectiveness of EFB compost as an alternative source of potassium, analyze its effect on potassium nutrient uptake, and assess its impact on oil palm yields at PT Evans Group. This research method used a field experiment approach by comparing two treatments: a control treatment without EFB compost and a treatment with EFB compost at a dose of 50 kg per plant. The results showed that compost application had a positive effect on plants, as indicated by increased leaf potassium content in the compost treatment compared to the treatment without compost. Although the difference was not significant, these results indicate that compost plays a role in increasing potassium availability and uptake by plants, thus supporting better plant growth.

Abstract

Oil palm (Elaeis guineensis Jacq.) is a tropical plantation crop with high economic value and is one of Indonesia's mainstay commodities. The purpose of this study was to determine the level of basal stem rot (Ganoderma boninense) infestation in oil palm plants at the Pangkatan Plantation of PT. Evans Group, the magnitude of the resulting fresh fruit bunch (FFB) yield losses, and the relationship between disease severity and the decrease in FFB yield. The research method used was a survey method with a quantitative descriptive approach. The results showed that the level of ganoderma infestation in Block A1 was relatively low at 8.7%, but had a significant impact on oil palm productivity. Trees attacked by ganoderma produced lower fresh fruit bunch (FFB) weights than healthy trees, thus indicating that plant health significantly affects production results.

Abstract

This study aimed to determine the effect of fertilizer application with a concentration of 5 grams per liter on the vegetative growth of immature oil palm plants (TBM). The study was conducted for 4 weeks with observation intervals once a week, using two treatments: control and application of 5 grams per liter fertilizer, each with 10 replications. Observed parameters included plant height, number of leaves, stem diameter, and leaf length. Data were analyzed using ANOVA test and continued with DMRT test at the 5% level. The results showed that the application of 5 grams per liter fertilizer had a significantly different effect on all growth parameters compared to the control in each observation week. This treatment consistently resulted in higher growth, so it can be concluded that the application of 5 grams per liter fertilizer is effective in increasing the vegetative growth of immature oil palm plants.
