Background: Indonesia is rich in plants, one of which is leaf drop shit (Tagetes erecta) which has the potential as a vegetable insecticide. Diverse local plants will be very good if integrated in learning through modules so that they can help preserve local plants. The objectives of this study are: (1) to determine the effect of Tahitian Kotok (T. erecta) leaf extract on the mortality of Aedes sp. Mosquitoes. (2) determine the concentration of leaf extract of Tahitian Kotok (T. erecta) which can influence the mortality of Aedes sp. (3) compile teaching materials in the form of modules. Methods: This research is an experiment that is giving treatment and observation of Aedes sp. with 3 extractions of Kotok Tahi (T. erecta) leaves and 1 control treatment. The study was conducted with 4 replications, each: treatment 1 (0.5%), treatment 2 (1.3%), and treatment 3 (2%). The results of experimental research are then used as a basis for making modules and their feasibility tested.  Results: Based on the research data there is a very significant effect on mortality resulting from each given extraction concentration. Based on research at a concentration of 2%, the highest mortality effect from Aedes sp. that is, with an average of 92.5% with 37 deaths from 40 mosquitoes. Kotok (T erecta) leaf extraction can be used as an alternative in controlling Aedes sp. Conclusion: The results of the study can be used as learning resources in the form of modules and are feasible to use with the validation results of 85.2%.

Разработан новый быстрорастворимый продукт (кисель) с определенным фазовым составом и строением на основе молочной сыворотки и местного растительного сырья – черноплодной рябины (Aronia melanocarpa). Разработана модель технологии производства быстрорастворимого гранулированного продукта (кисель) на основе молочной сыворотки и черноплодной рябины. Исследована сохраняемость киселя в трех температурных режимах: 1-й (21 ± 1)°С; 2-й с низкой плюсовой температурой (5 ± 1)°С; 3-й с повышенной (39 ± 1)°С при влажности окружающей среды 80%. По окончании годичного исследования сохраняемости при температурных режимах (21 ± 1)°С и (5 ± 1)°С изменений в органолептических показателях продукта не наблюдали. Скорость растворения продукта при температурных условиях хранения (21 ± 1)°С и (5 ± 1)°С не изменялась на протяжении 9 мес. Установлено, что при хранении в условиях пониженных положительных температур 4–6°С и в режиме комнатной температуры (21 ± 1)°С исследуемый пищеконцентрат по окончании 6 мес. хранения не изменил свойств по показателям качества. Сроки испытания продукта превышали по длительности в 2 раза заданный срок хранения (коэффициент запаса). Результаты испытаний явились основанием для разработки технической документации на производство быстрорастворимых гранулированных плодово-ягодных киселей. A new fast – soluble product (kissel) with a certain phase composition and structure based on whey and local plant raw materials Aronia melanocarpa. A model of technology for the production of a rapidly soluble granular product (kissel) based on whey and Aronia melanocarpa has been developed. The stability of kissel in three temperature modes was studied: 1st (21 ± 1)°C; 2nd with a low plus temperature (5 ± 1)°C; the 3rd with the increased (39 ± 1)°C at 80% ambient humidity. At the end of a year-long study at temperature conditions (21 ± 1)°С and (5 ± 1)°С, no changes in the organoleptic characteristics of the product were observed. Dissolution rate of the product under storage temperature conditions (21 ± 1)°C and (5 ± 1)°C did not change for 9 months. It is established that when stored at low positive temperatures 4–6°C. With and at room temperature (21 ± 1)°C. At the end of 6 months of storage, the food concentrate under study did not change its properties in terms of quality. The product testing period was 2 times longer than the specified storage period. The test results were the basis for the development of technical documentation for the production of instant granulated fruit and berry kissel.

The main proposal of the circular economy is to change the concept of "garbage" fromWaste that was structured in this project and replaced by a continuous and cyclical vision of the production, in which resources are no longer just explored and discarded and are now reused in a new Cycle. The Circular Economy encourages new management practices, creating opportunities and value for organizations in harmony with the environment. This article aims to analyze the feasibility of implementing Circular Economy methods, with an emphasis on controlling scrap disposal in the Açu Port Complex (São Joãoda Barra/RJ), bringing sustainable alternatives to Waste Management. In addition to evaluating its environmental and economic efficiency, it proposes to end the linear production process and reinsert waste into the production cycle to minimize environmental treatment and the extraction of raw materials. The investigation will start through specific exploratory research, bringing as a consequence, possible economic alternatives for the reuse of these materials. The research is also classified as descriptiveand case study since a survey of real information on waste management in the Açu Port Complex will be carried out. It is hoped through this research to demonstrate how the circular economy can contribute to economic, social, and environmental development when used in an interdisciplinary way by productive activities.

The aim of this study was to determine the physical and mechanical properties of Cross laminated timber (CLT) made from oil palm (Elaeis guineensis. Jacq) stem waste combined with thinned platinum teak (Tectona grandis ) wood. CLT was made into two types, namely CLT type A (teak-palm-teak) and CLT type B (teak-teak-teak). The CLT was 150 cm in length and 20 cm in width, with variation of the thickness of 3,0 cm, 4,5 cm, and 6,0 cm, and the glue spread of 300 g/m². The results showed that CLT type B has better physical and mechanical properties than CLT type A. Generally, CLT made of lamina with a thickness of 4,5 cm showed the best performance of physical and mechanical properties. Platinum teak and palm oil stem waste have the potential to be used as a source of CLT raw materials because of the moisture content, flexural modulus (MOE), and fracture modulus (MOR) that meet the JAS 1152 standard.Keywords: Cross laminated timber, platinum teak, oil palm stem, physical properties, mechanical properties

Studies on women in informal sector have not sufficiently addressed their challenges and support mechanisms. This study was conducted among women in informal sector in Iwo, Osun State. Social network and liberal feminist theories were adopted. This exploratory research was conducted in three locations in Iwo town namely; Adeeke, Odori and Boku Soro. The selection of respondents was purposive, based on type and duration of involvement in business. Twenty in-depth interviews were conducted with respondents to elicit information on reasons for entry into business, challenges faced, support mechanisms available and awareness and utilization of loans from financial institutions. Data were analysed using content analysis and verbatim quotations. Reason for entry into the businesses included; interest, economic purpose, inability to get jobs, support to family and supplementing spouse income. Financial supports were from various trade associations and cooperative societies they belonged, while nonfinancial supports were close family members like children run errands and assist in processing raw materials to semi or finished products. Most respondents were aware of loans provided by various financial institutions, however, they hardly utilized them. There is the need to carry out adequate enlightenment and education women in accessing soft loans provided by microfinance banks in sustaining, improving and expanding their businesses.
