Buletin Loop of the Politeknik Pertanian Negeri Samarinda is one of the most active centres of scientific work in agriculture in the Samarinda. Problems are attacked from two distinct points of view: the economic, in which the object is to show how crops may be produced a little more cheaply than at present, and the scientific, the problem being investigated for the sake of the general principles it may bring out. Two sets of bulletins are therefore issued, the popular bulletin, intended for farmers, dealing mainly with local problems, and always from the local point of view, and the research bulletins. The popular bulletins are fully equal to any others in the United States, and much ahead of anything we publish here for farmers; in the series before us the subjects dealt with include land drainage, curing of seed corn, control of various weeds, draft-horse judging, a discussion of the methods of paying for milk at cheese factories, and so on. The research bulletins are the scientific papers of the staff; as usual in the Samarinda, each paper is published separately, and there is no common journal in which they all appear.

Abstract

Weeds growing wild among the staple crops cultivated by farmers have become a serious problem and must be immediately controlled, especially in forestry, agricultural and plantation areas. Therefore, practical knowledge is needed about how to manage the problem of weeds that grow undesirable and how to overcome them. Non-chemical weed control is carried out with physical activity. Physical activity carried out by workers while working is a physical workload that will affect their work productivity. The weight or lightness of work done by workers can be measured through direct measurements of human limbs or physique, among others, heart rate, blood pressure, body temperature, sweat rate, consumption of inhaled oxygen and chemical content in the blood. This study aims to identify the use of semi mechanical weed tools and brush cutter as well as analyze the physical workload experienced by workers. The stages and methods of research are carried out by measuring and testing tools in the field based on technical aspects including theoretical work capacity, effective work, field efficiency, fuel consumption, while ergonomic work aspects by measuring workload and fatigue levels directly on the operator's heart rate. From the measurement and calculation of the Increase Ratio of Heart Rate (IRHR), the lowest workload level was obtained with an index of 1.15 and the highest workload level of 1.51.

Abstract

Brondolan is an oil palm fruit that is separated from spikelets because it is too ripe during harvesting activities. Apart from that, brondolan is part of the fresh fruit bunch which produces maximum quality Crude Palm Oil (CPO). The aim of this research is to analyze losses from harvesting activities in the form of oil palm fruit stalks. The research method is to carry out quantitative and descriptive analysis. Loss of brondolan fruit during palm oil harvesting activities from the research sample was 10% of the sample block area in the disk area, pickle market area and yield collection area (TPH), amounting to 16,946 Kg/month of the total Kg/division oil palm fruit production. This occurs because the fruit is abandoned or left behind as a result of weak supervision and poor maintenance or maintenance activities in the plate area, pickle market area and TPH area which are not controlled by the growth of weeds, kentosan, this has an impact on the potential loss of 3,2% of total TBS production in the division.

Abstract

Durian peel is one of the agricultural wastes that has great potential to be processed into high-value products. However, its utilization is still not optimal due to the lack of information about the strategic location of this raw material. This article aims to discuss the use of Geographic Information System (GIS) and IT technology in identifying the optimal location of durian peel raw materials. GIS is a very effective tool for collecting, managing, and analyzing spatial data related to the location of raw materials, making it easier to determine strategic points for durian shell collection. Architectural design that considers aspects of sustainability, energy efficiency, and minimizing environmental impact, treatment facilities can operate more efficiently and environmentally friendly. Industrial engineering also plays an important role in improving the efficiency of the processing process. By applying the right industrial techniques, the production process can be optimized to produce high-value products at a lower cost. The use of GIS and IT technology, coupled with the principles of environmentally friendly architecture and industrial engineering, can provide a comprehensive solution to optimize the use of durian peel as a raw material for high-value products.

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

This research is motivated by the lack of optimal use of bamboo, where bamboo is a natural material that is relatively cheap, easy to obtain and is one of the plants whose use in society is less optimized. In its role as a plant, bamboo can also be used as a material for making liquid smoke for various food needs which can be used for preservation. Shrimp is also a food that people really like, but shrimp cannot last long so natural additives are needed so that shrimp can last longer. Therefore, this research aims to determine the effect of providing liquid smoke from bamboo on shrimp quality, including changes in the smell and texture of shrimp. Observations were carried out at the Non-Wood Forest Products Laboratory, Forest Products Processing Study Program, Samarinda State Agricultural Polytechnic. The research method was carried out by observing shrimp without preservation (control), preserving shrimp with different concentrations, namely 5%, 7% and 9%. Observations of changes in the smell and texture of preserved shrimp were carried out for 6 days. The research results showed that preserving shrimp using liquid smoke from grade 1 bamboo material at a concentration of 7% was more effective than the control, liquid smoke concentrations of 5% and 9%.
