Frond base fracture is an increasingly common phenomenon in oil palm plantations caused by various stress factors. This study aimed to determine the incidence of frond base fracture in the plantation where different nutrient sources were applied (palm oil mill effluent, oil palm EFB, and organic fertilizers) in relation to the dynamics of oil palm inflorescence. The incidence of frond base fracture and the production of male and female inflorescences were observed in 30 sample trees for each nutrient source. Observations were made three times with an interval monthly. To reveal the research objectives, it used descriptive analysis. The results showed that the routine application of POME increased the susceptibility of oil palms to fractured fronds and the sex ratio was higher other than that of EFB; the lowest incidence was found in the palm that was given inorganic fertilizers. frond base fracture trees produced fewer female inflorescence, although the number of male ones did not differ between frond base fracture palm and healthy ones.

Basal stem rot caused by Ganoderma boninense is the main disease of oil palm plantations. The disease decreases yield, causes plant death, shortens economic life, and accelerates replanting. The purpose of this study is to compare the development of this disease in third-generation oil palm plantations in peat soil and mineral soils. Observations were made to verify secondary census data for 4 years on affected (endemic) rotten stems. Observations were made on each of the 3 blocks for peat soil and mineral soil with palm oil planting year 2011-2012. The results showed that stem base rot develops faster with a higher severity in peat soil than yellow-red podsolic soil. The availability of organic matter in both soil and oil palm plant residues becomes an important source of nutrients for pathogenic fungi in completing the cycle of disease in plantations.

Replanting of smallholder oil palm plantations is carried out to replace plants that have passed the economic age of 25 years and / or plants whose productivity is less than or equal to 10 tonnes of FFB / ha/year. In order for this replanting policy to be realized, support for the development of human resources is needed to increase the knowledge, skills, and abilities of farmers in carrying out sustainable oil palm cultivation and to grow, develop and strengthen smallholder institutions. This study aimed to analyse the readiness of farmers for oil palm replanting programs. The data used in this study are primary data and secondary data. Primary data collection techniques obtained through direct interviews with respondent farmers using a questionnaire and direct observation. Secondary data is obtained from data on the agronomic character of oil palm and related institutions or agencies such as the plantation office and BP3K as well as other literature such as journals, theses, publications, and other literature related and relevant to the research. From this research, information regarding the replanting model, replanting cost, and agronomic character carried out by the farmers will be obtained.

Bahan baku dan proses sterilisasi dalam pengolahan minyak sawit mempunyai peranan sangat penting terhadap sifat minyak sawit. Sampai saat ini bahan baku berupa tandan buah sawit dan proses pemanasan menggunakan uap panas. Penelitian ini bertujuan untuk mengetahui karakteristik minyak sawit dari metode pemanasan berbeda dengan bahan baku buah sawit yang lepas dari tandannya (brondolan). Metode penelitian menggunakan rancangan percobaan faktorial dengan 2 faktor. Faktor I adalah metode pemberian panas terdiri dari 3 taraf ; P1 = pemanasan dengan cara dikukus, P2 = pemanasan dengan udara panas, P3 = pemanasan dengan steam dari sterilizer. Faktor II adalah waktu pemanasan terdiri 3 taraf ; t1 = 30 menit, t2 = 60 menit, t3 = 90 menit. Parameter pengamatan meliputi kadar asam lemak bebas (ALB), kadar minyak mesokarp, deterioration of bleachability index (DOBI), dan kadar kotoran. Hasil penelitian menunjukkan lama waktu pemanasan berpengaruh terhadap ALB, DOBI, dan kadar minyak mesokarp, tetapi tidak berpengaruh terhadap kadar kotoran. Semakin lama pemanasan semakin meningkatkan ALB dan menurunkan DOBI. Metode pemanasan brondolan buah sawit berpengaruh pada ALB dan DOBI, tetapi tidak berpengaruh terhadap kadar kotoran, kadar minyak mesokarp dan metode dikukus memberikan hasil yang lebih baik.

The productivity of Fresh Fruit Bunch (FFB) in Indonesia is relatively low with an average productivity of below 15 tonnes.ha-1.year-1,which is still very far below its potential, which is around 25 tonnes.ha-1. year-1, one of the contributing factors is the application of fertilizers. neither the type nor the dose has been done precisely. Research on Determining Fertilizer Dosage Based on FFB Â tonnage data for oil palm plantations has been carried out from March to October 2022 at a private oil palm plantation company located in Nunukan Regency, North Kalimantan Province. The research was carried out on an area of â€‹â€‹812 ha which was divided into 28 blocks, consisting of 7 treatments each carried out in 4 blocks as repetition. The soil pH conditions are relatively neutral, namely between 6.0-6.9. Fertilizers used are also of various kinds, namely Urea, Rock phosphate, Muriate of potash, Kieserit and Dolomite. The dosage of fertilizer is determined based on the tonnage of fresh fruit bunches produced and compared with the dose of fertilizer according to the recommendations from the leaf sampling unit. This study uses monthly data for each block from March to October 2022 which includes: average stem weight (BJR), number of stems per tree (JJG/PKK), and productivity (tons.ha-1.month-1). The data obtained were then analyzed for variance and continued with Duncan's multiple range test. The results showed that in March, April and October there was a significant difference between the treatments where in March there was a difference in the productivity of fresh fruit bunches where the application of Urea-Rph-MOP-Kieserite fertilizer was 4.3-2.5-1 respectively. .9-2.9 respectively in kg.principle-1.year-1 (P1) shows the highest productivity. In April and October there was a significant difference in the yield per tree where in April the Urea-Rph-MOP fertilizer application treatment was 2.4-1.6-1.8 respectively in kg.principal-1 year-1 (P5) showed that the number of shoots per tree tended to be higher than the other treatments, whereas in October the number of stems per tree tended to be higher in treatment P1. However, there was no significant difference in average length weight from March to October. Thus the dosage of fertilizer can be determined based on fresh fruit bunch tonnage data as an option other than based on the results of leaf sampling units to be implemented in the field.

La Nina is a climate anomaly that can cause extreme weather. La Nina is marked by a decrease in the sea surface temperature of the Pacific Ocean at the equator. La Nina can cause a prolonged rainy season for Asia including Indonesia. From mid-2020 to the end of 2022, Indonesia has experienced La Nina events. This study aims to determine changes in rainfall patterns and the number of rainy days during La Nina events. This research was conducted descriptively, using Pacific Ocean sea surface temperature (SST) data and rain data originating from the BMKG Climatology Station of Sultan Syarif Kasim II Pekanbaru from data for the last 10 years 2013-2022. The results of the study show that La Nina occurred from October 2020 to December 2022 with a weak to moderate level of La Nina strength. La Nina has increased the amount of rainfall 54-90% from normal conditions and increased the number of rainy days 11-70% compared to climate with normal conditions. Monthly rainfall is in the low to high category, while daily rainfall is included in the heavy rain category. The La Nina event has caused a prolonged rainy season for almost 3 years and has increased the amount of rainfall and rainy days.
