Abstract

The existence of weeds on agricultural land causes competition with cultivated plants in obtaining nutrients, water, and sunlight. Therefore, it is necessary to carry out weed control so as not to interfere with the growth and development of cultivated plants. This study aims to find out the types of weeds that grow in the disc area and to find out the most effective herbicides based on the content of active ingredients in controlling weeds in the oil palm disc area. Sampling was carried out by purposive sampling technique. Based on this technique, 2 blocks were obtained as research locations, namely block 73B and block 68A with a sample area of 351 m2 in each block. In this area, 9 sample plots were made with the size of each plot 1 m x 1 m. The object of the study was in the form of weeds in the sample plots that were given different treatments, namely using a single herbicide using a Kenfosat herbicide with the active ingredient isopropyl amine glyphosate with a dose of 2 liters/ha in block 73B and a mixed herbicide consisting of a Kenfosat herbicide with the active ingredient isopropyl amine glyphosate + Mitsufuron herbicide with the active ingredient methyl metsulfuron + agristick with the active ingredient alkyllaril polyglycol ether with a dose of 2 liters/ha + 0 each, 075 gr/ha + 0.1 liters/ha in block 68A. The results showed that the types of weeds that grew in the oil palm disk area were broad-leaved weeds such as Ageratum conyzoides, Asystasia intrusa, Clidemia hirta, Phyllanthus urinaria and narrow-leaved weeds such as Setaria plicata. Based on the content of the active ingredient, the most effective herbicide in controlling weeds in the oil palm disc area is a mixed herbicide because it is able to kill weeds completely (100%) on the 15th day after the herbicide application.

Abstract

Many accidents in oil palm plantations are caused by risks such as harvesting activities. Even though the K3 system has been implemented, accidents still occur because there is a high potential risk of work accidents, so companies need to manage them so that the level of work accidents can be reduced. Research objectives: identify potential dangers and risks of work accidents for harvest employees, carry out an assessment and analysis of the level of value of the risk of harvesting work activities using the HIRARC method and recommend ways to control the potential risk of work accidents during harvesting based on the K3 risk management hierarchy, namely substitution, elimination, PPE and administration. Activities identified as having potential dangers and risks are sharpening tools, cutting fruit, cutting midribs, transporting fruit to TPH, and arranging fruit in TPH. There are 2 levels of risk assessment, namely low risk low risk (sharpening tools, cutting fruit at risk of being injured by thorns and the risk of material waste being exposed to sore eyes, arranging fruit in TPH), medium risk, medium risk (cutting the fronds at risk of falling fronds, swelling from wasp stings and fever, transporting fruit to TPH), and controlling risks such as substitution, elimination, using PPE, administration and being careful when working and paying attention to land conditions.

Abstract

Weeds frequently present challenges in agricultural settings, leading to crop damage and diminished yields.  The size of the current weed population is often closely linked to these issues.  The primary factor at play is the competition between crops and weeds for space, nutrients, and light essential for growth.  Given that weeds are considered undesirable, their control represents a significant area of focus.  A method to assess effective weed control strategies involves vegetation analysis, offering insights into weed distribution and density.  The data aids in formulating an effective control strategy to reduce the adverse effects of weeds on oil palm yield. This investigation seeks to analyze the composition and structure of weeds, as well as evaluate the efficacy of weed control measures on ex-burned land.  This study employs field surveys to catalog the types and quantities of individual weeds, alongside vegetation analysis to assess weed structure through relative density, frequency, and dominance metrics. The findings revealed a total of 275 distinct weed compositions, encompassing 15 species across 10 families.  The prevalent weed species identified included Eleocharis dulcis, Paspalum conjugatum, and Fimbristylis miliacea.  The density, frequency, and dominance values of these three weeds were notably high.  The weed diversity index in the peatland was measured at 2.13, indicating a high classification.  The approach to weed management involves an integration of both physical and chemical techniques.

Abstract

This research is motivated by the processing of palm oil, transportation factors get special attention.The transportation of palm fruit from the garden to the factory should be as fast as possible so that thefruit harvested today can be processed directly so that free fatty acids are not high. Extensive oil palmplantations and garden conditions far from the factory, it will be more difficult to regulate the entry ofFresh Fruit Bunches (TBS) to the Palm Oil Factory (PKS), so that the company must have a goodmanagement system that can run effectively and efficiently so that it needs proper transportation forperushan so that it can transport all tbs harvested by minimizing time, cost and maintain the quality ofTBS.From the description above, the formula that can be formulated in this study is to know the time oftransportation, the needs of transport equipment and what obstacles are encountered at the time of TBStransportation. While the limitations of the problem there is tbs transport research contained in fadelingBrafo, Alfah and Delta with different distances (near, medium and farthest). The purpose of this researchis to know the process of planning the needs of TBS conveyances, as well as knowing the obstacleswhen transporting TBS.The results of research conducted at PT. Berau Karetindo Lestari shows that tbs transportationplanning includes the production of TBS per day, TBS transport time, availability of conveyance,transportation needs and constraints in transportation. In Bravo afdeling requires 2 units of tarktor, forafdeling Alfah 4 units taktor, and afdeling Delta requires 3 units of tractor. As for the needs of the truckon Loading ramp 1 as many as 10 units and Loading ramp 2 to 8 units. This is obtained after calculatingthe number of transport equipment needs to transport TBS every day. For the overall needs of thecompany, tractors are needed as many as 17 and DT as many as 18 units. As for the obstacles at thetime of tbs transportation, namely, the road conditions in TPH are not good and the distance of thefactory is so far that it takes so much time to get to the factory.
