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

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%.

Abstract

Kaliandra (Calliandra calothyrsus Meisn) is a plant capable of producing large amounts of biomass, potentially as a renewable energy source that supports the reduction of dependence on fossil fuels. The transition from fossil fuels to renewable energy is an urgent and long-term solution, as the use of fossil fuels as an energy source contributes to global warming and climate change.This study aims to evaluate the effect of compost fertilizer dosage and compost tea on the growth of height and diameter of kaliandra seedlings. Using a one-factor complete randomized design (CRD) method with treatment of compost fertilizer doses K0 (0 grams), K1 (60 grams), K2 (75 grams) and K3 (90 grams) and compost tea doses TK1 (0 ml), TK1 (50 ml), TK2 (75 ml) and TK3 (100 ml). Research results: 1. The treatment of compost doses and compost tea showed significant differences in the height growth of calliandra seedlings. 2. Compost fertilizer with a dose of 90 grams (K3) showed a better height growth rate than compost tea fertilizer with a dose of 100 ml (TK3), 75 ml (TK2), and 50 ml (TK1). 3. Compost tea fertilizer with doses of 50 ml (TK1) and 75 ml (TK2) showed a better height growth rate than compost fertilizer with doses of 60 grams (K1) and 75 grams (K2). 4. The compost fertilizer dose treatment showed a significant difference in the growth rate of Calandra seedling diameter, while the compost tea dose treatment did not show a significant difference. 5. Compost fertilizer with doses of 75 grams (K2) and 90 grams (K3) showed better diameter growth than compost tea fertilizer with doses of 75 ml (TK2) and 100 ml (TK3). 6.  The optimal dosage recommendation in this study is 90 grams of compost fertilizer and 75 ml of compost tea.

Abstract

radiation, fast food, limited exercise time, stress due to work cannot be avoided, and also from the results of oxidation processes in the body. The development of degenerative diseases caused by free radicals can be inhibited by antioxidant compounds which are able to ward off free radicals. Therefore, the body needs important substances - antioxidants - that help protect it from attacks by free radicals and radical compounds. At certain concentrations, antioxidants can inhibit or slow down the damage caused by oxidative processes. Brewing time has an important role in determining the taste, aroma and active compound content of tea. The need for clear guidance regarding brewing times is becoming increasingly important, especially with the increasing interest in premium tea drinks and the influence of healthy lifestyles. This research aims to know the relationship between brewing time and tea quality in terms of dissolved antioxidant bioactivity content.  This research activity tested the antioxidant activity of Sapar leaf tea with different brewing times, namely 3, 5, 10, 15, 20 and 30 minutes. Antioxidant activity testing uses the DPPH (1,1-Diphenyl-2-picrylhydrazy,) method. From the test results it was found that Sapar leaf tea (Fordia splendidissima (Miq) Buijsen) with a brewing time of 3 minutes had the highest antioxidant bioactivity with a radical inhibition value of 81.46% and the antioxidant bioactivity decreased as the brewing time for the leaf tea became longer.

Abstract

Red palm oil is a palm oil derivative product, where refining is simple without a bleaching process, so it has good nutritional content (carotenoids or as pro-vitamin A, vitamin E, tocopherols and tocotrienols), and also provides health benefits. However, there is no information on processing red palm oil by choosing a better separation method to produce red oil with maximum yield but still good quality. This research was carried out using 2 separation methods, namely centrifugation and sedimentation. The treatments consisted of different temperatures used during the process of homogenizing CPO (3 temperature variations), including P1 = 80℃, P2 = 70℃ P3 = 60℃. This research used a CRD. From the results of the studies, it was concluded that difference in fractionation method and temperature indeed had some effects on the yield and quality of red palm oil. Furthermore, the best yield results during the study were obtained by centrifugation at 80°C temperature The yield was 69% and the quality characteristics were free fatty acid content of 2.78%, water content of 1.61%, DOBI value of 2.03, and beta-carotene content of 423.05 ppm.
