It is necessary to carry out replanting  activities  to increase  the production and productivity of oil palm plants.  Rejuvenation of oil palm plantations can be done through an inserting system  and totally rejuvenation system. The population propagation of horn beetles  growed faster  in oil palm plantations with inserting rejuvenation system than in totally rejuvenation system. This study aimed to obtain an accurate information on the population of horn beetles in oil palm plantations. The research has been conducted on  July-August 2020  in Talang Bukit Village as an inserting system area Talang Datar Village as a totally rejuvenation area, Bahar Utara District, Muaro Jambi Regency, Jambi Province. An unformated trial was carried out as an experimental design and the location determination was purposively chosen  for there were plants under study and showed a uniform condition at that location.  the sampling locations based on oil palm plantation rejuvenation systems, namely: (1) inserting rejuvenation system, and (2) totally rejuvenation system. There were 15 / Ha population at oil palm plantation with inserting rejuvenation system,  while there were 3 horn beetles/Ha in totally rejuvenation system. The percentage of horn beetle attacking was 22,22 in  inserting rejuvenation system while it was only 3.70%. in the  totally rejuvenation system.Key words: population, horn beetle,  rejuvenation, oil palm

Oil Palm Plantation

Purpose The purpose of this paper is to develop strategies for potential environmental impacts as a result of institutional arrangement and development of oil palm downstream industry both regionally and nationally. Design/methodology/approach The research location is in the areas potential for oil palm plantation development, either by plasma through BUMN and BUMS or self-supporting by the society. The research location will be divided into two parts, namely, the land area and the coastal area. The Riau land areas are Regency of Kampar, Rokan Hulu, and Kuantan Singingi, while Riau coastal areas are Regency of Pelalawan, Siak, Bengkalis, Indragiri Hilir, Indragiri Hulu and Rokan Hilir. Both research areas have different productivity due to the different soil fertility levels. The sustainability level of oil palm plantation from the socio-economic and environmental aspects is analyzed using the multi-dimensional scaling approach modified into Rapid Appraisal-Index Sustainability of Palm Oil Management. Findings In Riau Province, the development of oil palm is quite rapid. This is reasonable for several reasons which include the following supporting factors: the geographical condition of the Riau region is very supportive; the high demand for palm oil derivative products; the existence of market guarantee for oil palm farmers; the higher income oil palm generates than other plantation crops; and the relatively flat area. Most of the problems faced by oil palm farmers are the use of less good seeds, the length of the fruit laying at the location of the plantation, the inadequate production road, the relatively far distance to palm oil mill (POM) (National Agency of Drug and Food Control), the tendency of determining the unilateral revenue of the POM, the collectively measurement of revenue and the general revenue information. The development of oil palm plantations has created an entrepreneurial capability for farmers who are able to capture business opportunities in the agricultural sector, especially the plantation sub-sector. Originality/value The originality of this paper shows the comprehensively control strategy, potential of environmental impact and palm oil plantation. The method used for data collection was rapid rural appraisal method because accurate information is needed in a limited time as it relates to decisions related to village development that must be taken immediately. The study area was conducted in Riau Province because Riau Province is one of the biggest palm oil producers in Indonesia. The study sites will be divided into two, namely, the land area and the coastal area.

Oil Palm Plantation

Nowadays, there are more women workers occupying various types of works, and it expands to the area of oil palm plantation. One of which  is women workers who work at fertilization section in oil palm plantation. This condition is vulnerable for the women workers due to the dust exposure from urea fertilizer. There are some likely possible risk jobs encountered by the women workers such as pulmonary function impairment indicated by lung vital capacity. From pre observation, it was found out that there were 60% of women workers who committed to respiratory disorders. About 80% from the women workers did not use proctected mask during the process of fostering the plantation. As a result, the long term goal of conducting this research is to get accurate information on the determinant factor of lung vital capacity of women worker at fertilization section which can be grounded as basic recommendation for the arrangement of Occupational Health and Safety (OHS) at oil palm plantation.Based on the problem identification, this research was designed by employing quantitative method of research with cross-sectional design. The observed and analyzed variables were the characteristics, the description of lung vital capacity of women workers, and influential factors to the lung vital capacity. This research was conducted to 50 women workers at fertilization area in oil palm plantation, Kebun Gunung Emas Kalimantan Barat. The data were analyzed through 2 phases of analyses namely univariable analysis and bivariable analysis using chi square test and prevalence ratio (PR). The findings of the research revealed that the associated factors with the lung vital capacity of women workers on fertilization area were the dust exposure (p value = 0,000 ; r = -0,650**) while the age variable, years of service, and nutrional status were not related to the lung vital capacity of women workers on fertilization area. The unanalzyed variables resulted from the homogeneity data were the length of exposure, and the use of personal protective equipment (PPE). All women workers rarely used PPE with its length of exposure 4 hours per day. As a result, it is recommended to the management of the oil palm plantation to make a policy on the obligation of using PPE for women workers at fertilization area because the amount of dust exposure exhaled by the workers is the main factor. It is also expected that the company can promote a counselling for the workers to do fertilization safely.

The aim of this study was to reveal the increase of farmer family income at oil palm plantation and dairy farm in supporting the comodity of plantation in Indonesia especially Riau Province. Survey method was applied in this study in which the samples were collected as the purposive sampling. Result of the experiment showed that integratiob system of raising cow within oil palm plantation might have a good petency in supporting the development of the oil palm plantation. Cows would provide organc fertilizer and improve the soil tecture and this integration system could reduce the production cost. Selection of farmer could be based on location determination, program socialisation, participative plan, development activity and evaluation of program. This program could contribute to the farmer income that could be an alternative side income  especially during low oil palm price. The farmer income  was around  Rp 3.600.000 ha-1 farmer-1 from at oil palm plantation and Rp 4.819,500,- month-1 farmer-1. The total farmer income was around Rp 8.419,500,-

Oryctes rhinoceros L. and Xylotrupes gideon L. (Coleoptera: Scarabaeidae) are known to attack palms. O. rhinoceros is a major pest in oil palm while X. gideon is a minor pest found in certain areas with a relatively few numbers. Collecting these beetles by hand picking and trapping are intended to reduce their population. Objectives of this study were to describe an intimacy of shared existence of O. rhinoceros and X. gideon in the oil palm plantation, and to determine the effect of manual collection of the beetles from the decomposing trunks compared to those that were collected using attractant traps. The study was conducted in Asahan Regency, North Sumatera, in Sei Silau PTPN III oil palm plantation. Five traps (2 Ha/trap) containing the pheromone ethyl-4-methyloctanoate were installed randomly at a replanting area of immature palm. Beetle collection was performed daily for 30 consecutive days using two methods, i.e. (a) hand-picking of beetles on the decomposed trunks at surrounding the trap for 2 hour per day, and (b) using pheromone traps. Simple regression and correlation model was used for data analysis. Results showed that coexistence of O. rhinoceros and X. gideon was observed at the breeding sites of decomposing trunks, but not in the traps, and their coexistence showed a weak relationship (r = 0.12). Number of collected O. rhinoceros (221 beetles) was much more than X. gideon (82 beetles). Natural sex ratio (male: female) was approximately 0.5 for O. rhinoceros and 0.4 for X. gideon. Collection of the beetles in the decomposed trunks showed a moderately positive relationship (r = 0.43) with, and significantly influenced (18.73%) to the collection of beetles using pheromone traps.

Eddy Covariance Measurements

<p>In tall vegetation canopies, such as forest or oil palm monoculture plantations, the below-canopy airflow can be influenced by the local topography and thereby cause horizontal exchange of the below-canopy air. Especially during night time, calm weather conditions may result in the formation of an isolated layer near the surface, which is decoupled from the above-canopy air layer. When decoupling and below-canopy horizontal air flow occurs, there is a high potential that above-canopy measured carbon dioxide (CO<sub>2</sub>) fluxes based on eddy covariance measurements might not represent the true ecosystem CO<sub>2</sub> flux as below-canopy respiration might be undetected by the eddy covariance system. Nevertheless, eddy covariance data are frequently used as the reference for fluxes of tall vegetation ecosystems or for validation of modelling approaches estimating gross primary production (GPP) and net ecosystem exchange (NEE). It is therefore important to have accurate information on air mixing, decoupling and sub-canopy drainage flow to understand the complex CO<sub>2</sub> exchange behaviour in tall vegetation ecosystems.</p><p>In this context, we investigate wind and micrometeorological dynamics of a mature oil palm monoculture plantation (tropical lowland, Jambi Province, Sumatra, Indonesia). We use data from above- and below-canopy eddy covariance and micrometeorological measurements within the oil palm plantation to assess the wind dynamics and the strength of the turbulent mixing as an estimator for the degree of coupling. Further, we explore the potential implications of decoupling and horizontal below-canopy flow on the above-canopy derived NEE.</p><p>Preliminary results show that wind is generally weak in the oil palm plantation. Using a breakpoint analysis, the correlation of below- and above-canopy standard deviation of vertical wind speed (σ<sub>w</sub>) derived from sonic eddy covariance measurements below (2.4 m height) and above the canopy (22 m height), we identified a site-specific σ<sub>w</sub> threshold of 0.11 m s<sup>-1</sup> (below-canopy) and 0.26 m s<sup>-1</sup> (above-canopy) above which the atmospheric conditions are in fully coupled state. During the day, unstable conditions dominate over stable conditions while in the twilight hours and during the night, the reverse is the case. Below-canopy wind comes mostly from south-eastern directions during both day and night, and tends to blow independently from wind above the canopy for conditions with above-canopy u* < 0.3 m s<sup>-1</sup>. Based on the above-canopy eddy covariance NEE measurements and on the direction difference (ΔWD) between above- and below-canopy wind, we observe a threshold of ~70° ΔWD above which the two layers might be decoupled. Below-canopy air flow might therefore influence the above-canopy NEE detections, biasing carbon balance estimates.</p>

Cultivation of oil palm is inseparable from pests. One of the main pests that attack oil palm plants is  the rat class which can cause  oil palm plantations get a high losses. The aim of this study was to determine the attacktion  intensity of  the bush rat (Rattus sp) in   Oil Palm smallholder at  Suko Awin Jaya Village, Muaro Jambi Regency. The research was carried out from February to April 2021 at the oil palm smallholder specifically  farmer group“Ridho Ilahi”. The experimental design was  unformated trials, and the location was purposively  chosen. The location determination of the sample was based on to  the initial survey that there was found     rats attacktion in this place. Sampling was carried out concurrently at the time  fresh fruit bunches harvesting,   fruit counting in the bunch, counting the number of fruits eaten by rats, counting good fruit (free from rat pest attacks), and weighing the weight of fresh fruit bunches. Parameters observed were the attacktion  level in the land, attacktion  intensity, production per hectare, environmental sanitation conditions. The rats attacktion  rate of  100%, means that all sample  in one stretch of   plantation  have been   attackted by rats, it was indicated by a bite scars on the harvested fresh fruit bunches. The attacktion intensity of the bush rat pest was 23%. The average production was 21.6 tons/hectare/year. The sanitation conditions on the land was partially overgrown with weeds and there were piles of midrib in the area between the certain two path of oil palm tree.

ABSTRAK   Indragiri Hilir is a district in Riau Province where around 70% of the population depends on coconut plantations. In 2018, a large population explosion of coconut beetles, Oryctes rhinoceros was reported in several regions in the Province. The population explosion that occurred in Sungai Nyiur Village, Tanah Merah Subdistrict, has caused conflicts between the community who own coconut plantations and oil palm plantation companies in the area related to the source of pest outbreaks. The regional government has formed an independent team to conduct scientific studies to examine this problem. The independent team in charge consisted of 12 personnel involving universities (UIR) and Riau BPTP agricultural institutions. The steps taken include surveys, interviews, field investigation, and trapping. The survey was conducted to determine the epicenter of the attack by evaluating the intensity of the damage visually and with the drone aid. Excavation and inspection of breeding sites were carried out to evaluate the presence and presence of beetles and larvae. Pheromone trap installation is intended to analyze the distribution of coconut beetles. Interviews were carried out both for coconut farmers and staff of oil palm plantation companies related to the chronology of beetle pest explosion and activities carried out on oil palm plantation companies.  The findings obtained from the study conducted were presented to both parties in dispute and also the Regional Government of Indragiri Hilir as described in this paper.
