Abstract

Many companies have been consuming natural resources and energy in unsustainable systems in recent years. This has released many greenhouse gases and has caused various problems, especially for the environment, social and economic, originating from waste disposal and climate change, especially at the local level. However, many organizations have started implementing their work system with Green Management. This is due to the growing concern over pollution, depletion of natural resources and global warming. The application of Green Management to the world of work currently has various obstacles. These bottlenecks can be reduced by prioritizing bottlenecks as critical so that higher priority constraints can be used first to address issues more effectively with resources. Priorities like this are crucial, especially for developing MSMEs with minimal resources. This paper specifically aims to identify the factors hindering Green Management's implementation. The TOPSIS fuzzy method is used in making decisions by prioritizing obstacles from an environmental, social, and economic perspective. The results of the investigation indicated that lack of awareness/information, technology risks and weak policies were obstacles to implementing GM. Prioritizing barriers with different perspectives is one way to assist in making decisions or policies, especially for industry and MSMEs, in mitigating these obstacles more effectively.

Abstract

Penelitian ini mangkaji pengaruh waktu fermentasi terhadap produksi bioetanol dari limbah kulit nenas dan kulit jeruk sebagai sumber selulosa. Percobaan dilangsungkan dengan metode sakarifikasi asam dengan menggunakan HCl dan fermentasi anaerobik menggunakan ragi saccharomyces cerevisiae.  Setelah proses pemurnian produk hasil fermentasi, kadar bioetanol yang paling tinggi dari kulit nenas didapat sebesar 3,3%. Nilai ini dicapai pada saat fermentasi dilangsungkan selama 5 jam dan massa ragi yang ditambahkan sebesar 15 g. Sedangkan kadar bioetanol dari kulit jeruk terttinggi juga diperoleh pada waktu fermentasi 5 jam dan variasi massa ragi seberat 15 g yaitu sebesar 1,7%. Demikian juga halnya dengan volume bioetanol yang dihasilkan setelah pemurnian, dimana volume bioetanol dari limbah kulit nenas lebih banyak diperoleh yaitu sebesar 3,5 mL dibandingkan dengan bioetanol dari limbah kulit jeruk jeruk yaitu hanya sebesar 3,3 mL. Hal ini disebabkan oleh kadar gula yang terkandung didalam kulit nenas lebih tinggi dibandingkan yang terkandung dalam kulit jeruk. Oleh karena itu, pemanfaatan kulit buah nenas dan jeruk dapat digunakan untuk produksi bioetanol melalui pendekatan bioteknologi dengan menggunakan ragi saccharomyces cerevisiae.

Abstract

Penelitian ini bertujuan untuk memproduksi sirup glukosa secara enzimatis dari ubi kayu ketan. Enzim yang digunakan adalah α-amilase yang dihasilkan dari Bacillus licheniformis dan glukoamilase yang dihasilkan dari Aspergillus niger. Sirup glukosa diperoleh dari hasil hidrolisis pati yang terdiri dari pencairan, sakarifikasi, pemurnian, dan penguapan. Hasil hidrolisis berupa hidrolisat yang mengandung gula reduksi monosakarida (glukosa). Metode Anthrone dan Lane Eynon digunakan untuk menganalisis persentase total glukosa dan dekstrosa ekuivalen (DE). Hasil penelitian menunjukkan bahwa perlakuan terhadap rasio pati dan rasio enzim berpengaruh terhadap peningkatan yield DE dan total glukosa yang diperoleh. Yield DE tertinggi adalah 91,75%, diperoleh pada rasio pati 40% b/b dan total glukosa 93,86 mg/L dengan kombinasi volume rasio enzim 0,1:0,08 mL α-amilase terhadap glukoamilase. Sedangkan perlakuan menggunakan 20 % b/b pati menghasilkan yield DE 68,98% dan total glukosa 90,95 mg/L dengan volume rasio enzim kombinasi 0,08:0,08 mL α-amilase terhadap glukoamilase. Oleh karena itu, dapat disimpulkan bahwa kombinasi rasio enzim α-amilase dan glukoamilase berbanding lurus dengan rasio pati dalam meningkatkan yield total gula pereduksi sirup glukosa.

Abstract

Stunting is a public health problem that receives special attention because it is related to human resources in the future. Many studies state that stunting is related to nutritional problems in toddlers, only a few studies show that environmental factors are an indirect cause of stunting in toddlers. The purpose of this systematic study was to describe the relationship between environmental factors and the incidence of stunting in toddlers.  This literature study used a scoping review method by searching through several search engines such as Scopus and nature and science direct databases supported by Diponegoro University.  The articles selected for review are articles that contain the results of observational studies (cross-sectional, cohort and case control) that analyze environmental factors with the incidence of stunting in toddlers. From 7 articles, only 1 study stated that environmental factors did not affect the incidence of stunting, 6 other articles stated that environmental factors were an indirect cause of stunting in toddlers. Environmental factors related to stunting are the source of drinking water, the practice of haphazard defecation, the presence of animal waste in the living environment, environmental enteric dysfunction, the availability of proper toilet, the practice of washing hands with soap when feeding children, exposure to cigarette smoke, exposure to PM 2.5, household waste and clean and healthy living behavior.

Abstract

The emergence of mosque architecture in Indonesia is inseparable from the development of Islam entering Indonesia. The development of Islamic civilization at all times has produced many forms and types of mosques, so that in Indonesia the forms of mosques are very diverse, especially in Aceh, the city of Lhokseumawe. The existence of Islam in Aceh is proven by the many historical mosques with Islamic architecture that have survived to this day, but in fact the function of mosques is more than that, mosques also act as centers of education, spread of Islamic symbols, and become centers of community empowerment. This research process combines field research (field research) and library research, namely using a qualitative descriptive research form. The mosque building itself is synonymous with Islamic architecture, which has seven important elements including gardens, courtyards, domes, pointed arches, muqarnas, minarets and mihrab, while not all elements of Islamic architecture are found in every mosque building.
