This study aims to create a CFD model aligned with lab test results from previous studies, conduct simulation tests using several types of biomass as input and optimize the operating parameters of various types of biomass to produce optimum syngas. The method used in this research is literature study and modelling using Ansys Fluent software. The results of this study indicate that biomass is a source of new and renewable energy (EBT) which has abundant potential in Indonesia, but its use could be more optimal. Biomass gasification is one of the most promising techniques used to convert solid fuels into useful gaseous fuels, which can be widely used in many households and industrial applications such as power generation and internal combustion engines. This research implies that it can help determine the optimum equivalence ratio and feed rate for a gasifier that utilizes various types of biomass. By finding the optimal combination, the composting process can achieve higher energy efficiency, resulting in more energy being generated from the biomass used. Additionally, by knowing the appropriate equivalence ratio and feed rate, this research can assist in optimizing the biomass composting process in the gasifier.

Expression of The Human Imagination and Creative Ability in Visual Form 人的想象力和创造能力在视觉形式中的表现
IF 2.1 Pub Date : 2023-06-30 DOI: 10.58344/jws.v2i6.292

Art is a visible manifestation of human creativity and imagination. A song, a sculpture, or a painting, for example, are all the products of human expressions, as are all other forms of art. They are typically admired for their beauty or emotional impact, much like in art. The human eye will appreciate the skill and beauty of an artist when they are able to depict reality in paintings in such a realistic manner. Therefore, it indicates that an artist is experimenting with realism when we talk about portraying subject matter so truly and without any artificiality. In the visual arts, realism refers to the precise representation of live forms, perspective, and the nuances of light and color. Viewing the work of a realistic artist using a conventional media and style is extremely uncommon in Pakistani contemporary art. Viewing works that explore only methods, drawing, composition, and accurately duplicating reality is even more uncommon. This chance came about as a result of Ali Azmat's recent solo exhibition at the Canvas Gallery in Karachi. Despite his past vivid and stunning work, a series of large-scale, realistic black and white portraits of women stood out.
艺术是人类创造力和想象力的可见表现。例如,一首歌、雕塑或一幅画,就像所有其他形式的艺术一样,都是人类表达的产物。他们通常因其美丽或情感影响而受到赞赏,就像在艺术中一样。当一个艺术家能够在绘画中以如此逼真的方式描绘现实时,人类的眼睛就会欣赏他的技巧和美丽。因此,当我们谈论如此真实地描绘主题而没有任何人为因素时,这表明艺术家正在尝试现实主义。在视觉艺术中,现实主义指的是对生活形式、视角以及光线和色彩的细微差别的精确表现。在巴基斯坦当代艺术中,使用传统媒体和风格观看现实主义艺术家的作品是极不寻常的。只探索方法、绘画、构图、准确复制现实的作品更是罕见。这个机会源于阿里·阿兹马特最近在卡拉奇的帆布画廊举办的个展。尽管他过去的作品生动而令人惊叹,但一系列大规模的、现实主义的黑白女性肖像却脱颖而出。

This study aims to determine the factors that influence the production of field rice farming in Kalamus Village, Paku District, East Barito Regency. The research location is in Kalamus Village, Paku District, East Barito Regency. Location determination using a purposive sampling method. The sampling technique in this study uses the Saturated Sampling Technique, where the number of samples is equal to the total population, namely 35 farmers. Data analysis using multiple linear regression. The results showed that field rice farming activities were still carried out subsistence to support food security for farmers and their families. Based on the results of multiple linear regression analysis, partially, the factors that significantly influence the production of upland rice are planting area, seeds, and labor. In contrast, the pesticide factor has no significant effect on production. Swid management has been carried out permanently or no longer moving, and pesticides have been used in clearing land and handling pests and diseases of Paddy Field plants. So it can be concluded that although the results of the Multiple Regression Test show that pesticides do not have a significant effect on the production of upland rice, this may occur because, in general, the cultivators did not carry out maintenance on their land, only relying on the generosity of nature. Still, now with permanent land conditions, without burning, farmers must be able to manage their land with technology, especially clearing land and weeds, as well as pests and diseases using pesticides.
本研究旨在确定东巴里托县巴库区卡拉穆斯村稻田种植生产的影响因素。研究地点在东巴里托县Paku区Kalamus村。使用有目的的抽样方法确定位置。本研究的抽样技术采用饱和抽样技术,样本数量等于总人口,即35名农民。数据分析采用多元线性回归。结果表明,稻田种植活动仍在维持生计,以支持农民及其家庭的粮食安全。多元线性回归分析结果显示,部分影响旱稻产量的因素为种植面积、种子和劳动力。相比之下,农药因素对产量影响不显著。实行永久或不再移动的Swid管理,并在清理土地和处理水田植物病虫害时使用农药。由此可以得出结论,虽然多元回归检验的结果表明,农药对旱稻生产的影响并不显著,但这可能是因为一般情况下,耕种者没有对土地进行维护,只是依靠大自然的慷慨。尽管如此,现在有了永久的土地条件,没有焚烧,农民必须能够用技术管理他们的土地,特别是清除土地和杂草,以及使用杀虫剂防治病虫害。

The Significant Effects of Agricultural Systems on The Environment 农业系统对环境的重大影响
IF 2.1 Pub Date : 2023-06-15 DOI: 10.58344/jws.v2i6.291

The sustainability of our world and the ecological balance are significantly shaped by agricultural systems. The main environmental implications of agricultural practices are highlighted in this research with an emphasis on both the detrimental effects and proposed remedies to lessen these effects. By supplying food, fiber, and different raw materials, agricultural systems are essential for maintaining human populations. These systems, though, have the potential to have a significant negative or positive impact on the environment. An overview of the main environmental impacts of agricultural systems is given in this research First, agricultural systems play a significant role in the production of greenhouse gases. The release of carbon dioxide (CO2), methane (CH4), and element oxide (N2O), all of which are powerful greenhouse gases that contribute to climate change, is influenced using synthetic fertilizers, intensive livestock production, and changes in land use. Second, agricultural practices have an impact on water resources. The overuse of irrigation water can cause groundwater aquifers to be depleted and rivers and lakes to dry up. Additionally, the fertilizer and pesticide-contaminated runoff from agricultural fields can contaminate water sources, leading to eutrophication and harming aquatic ecosystems. Adopting sustainable agricultural practices is necessary to meet rising food demands while reducing adverse effects. These methods include organic farming, agroforestry, precision agriculture, and improved water management strategies. By putting such practices into practice, one can encourage a more resilient and sustainable food production system while also reducing the negative environmental effects of agriculture.
我们世界的可持续性和生态平衡在很大程度上取决于农业系统。本研究强调了农业实践的主要环境影响,重点是有害影响和减少这些影响的拟议补救措施。通过提供食物、纤维和不同的原材料,农业系统对维持人口至关重要。然而,这些系统有可能对环境产生重大的消极或积极影响。本研究概述了农业系统对环境的主要影响。首先,农业系统在温室气体的产生中起着重要作用。二氧化碳(CO2)、甲烷(CH4)和氧化元素(N2O)的释放都是导致气候变化的强大温室气体,它们受到合成肥料、集约化畜牧业生产和土地利用变化的影响。第二,农业生产对水资源有影响。过度使用灌溉水会导致地下水含水层枯竭,河流和湖泊干涸。此外,农田中被化肥和农药污染的径流会污染水源,导致富营养化,危害水生生态系统。要满足不断增长的粮食需求,同时减少不利影响,必须采用可持续的农业做法。这些方法包括有机农业、农林复合、精准农业和改进的水资源管理策略。通过将这些做法付诸实践,人们可以鼓励建立一个更具抵御力和可持续性的粮食生产系统,同时还可以减少农业对环境的负面影响。

The Cultural Conflicts on E.M. Forster a Passage to India: From Post - Colonial Perspective 后殖民视角下E.M.福斯特《印度之行》中的文化冲突

A Passage to India is an outstanding English novel from the early 20th century. This is the most successful novel written by EM Forster. Unlike other writers of fiction on colonial or postcolonial matters, Forster attempts to enrich the anti-hostile communication between British colonialists and colonized Indians in this acclaimed novel. The purpose of this study was to find out the beliefs and attitudes of British people towards non-English people that reflect cultural conflicts.This research uses a quantitative research type. Personal relations between Britain and India at the level of equality are difficult to encourage due to the superiority complex of the British and the nationalist sentiments of the Indians. The novel A Passage to India by EM Forster shows how cultural conflicts between British and Indians occurred repeatedly in India during the colonial period. The English in this novel see themselves as superior and treat the Indians with complete injustice. Finally, a British colonial presence in India was considered a very real possibility and gave rise to an ongoing cultural conflict. The novel A Passage to India, EM Forster illustrates the cultural clash between the British colonizers and the Indian colonized. The belief of British superiority over Indian culture creates a barrier to establishing personal relationships based on equality. This superiority complex and nationalist sentiment lead to cultural conflicts in India, emphasizing the damaging effects of colonialism on both colonizers and the colonized.
《印度之行》是20世纪初一部杰出的英国小说。这是EM福斯特写的最成功的小说。与其他殖民或后殖民题材的小说作家不同,福斯特试图在这部广受好评的小说中丰富英国殖民者和被殖民的印度人之间的反敌对交流。本研究的目的是找出反映文化冲突的英国人对非英国人的信仰和态度。本研究采用定量研究类型。由于英国人的优越感和印度人的民族主义情绪,英印之间在平等层面的个人关系很难得到鼓励。EM福斯特的小说《印度之旅》展示了殖民时期英国人和印度人之间的文化冲突是如何在印度反复发生的。小说中的英国人自认为高人一等,对待印第安人完全不公正。最后,英国在印度的殖民存在被认为是一种非常现实的可能性,并引发了持续的文化冲突。EM福斯特的小说《印度之旅》描述了英国殖民者和被殖民的印度人之间的文化冲突。认为英国文化比印度文化优越的信念,为建立基于平等的个人关系制造了障碍。这种优越感和民族主义情绪导致了印度的文化冲突,强调了殖民主义对殖民者和被殖民者的破坏性影响。
