Abstract

Smoking issue has become a major problem which need to adressed seriously by the Government, especially in Indonesia because smoking have killed millions of Indonesia children each years. The increase of smoking prevalence occurred in the age group15-24 years, from17.3% (2007) to 18.6% or increase almost 10 % in 3 years. The increase also occurred in the productive age group, that 25-34 years from 29.0% (2007) to 31.1% (2010). From these data it can be seen that most of teenagers are smoking. Adolescence is a period where a person wants to look fashionable. T-shirt is one of fashion trend which is much demand by teenagers. Above information make us innovate to open a business that also has a contribution in the control of smokers in Indonesia. We propose the effort of making T-shirts "TOBACCOREJECT TEES" which contains the message to quit smoking as well as smoking prevention messages. In the process we formed a partnership with Central Java Provincial Health Office, Store Entrepreneurship Diponegoro University School of Public Health and Keboe Chloth Distro Store. During the marketing process shirt "TOBACCO REJECT TEES" get very enthusiastic response from consumers. During the marketingt-shirts "TOBACCO REJECT TEES" has sold more than 136 pieces of T-shirts with a profit of Rp. 25.000/pcs.Key Words: Smoking, T-Shirt, Tobacco Reject Tees

Abstract

Universitas Islam Negeri Walisongo Semarang has participated in the Green Campus ranking program organized by the UI GreenMetric World University Rankings in 2019 and 2020. There are six (6) categories in the UI GreenMetric standard which were assessed, namely: Setting and Infrastructure (SI), Energy and Climate Change (EC), Waste (WS), Water (WR), Transportation (TR) and Research and Education (ED). In 2019 and 2020 the Universitas Islam Negeri Walisongo Semarang was ranked 384 in the World with a total of 912 University participants worldwide. This achievement was obtained Universitas Islam Negeri Walisongo Semarang received a total score of 5,625 in the assessment in 2020. The Energy and Climate Change (EC) indicator managed to get the highest total score process compared to other indicators (23 %), While the Water Indicator (TR) received the lowest score by only getting a score percentage of 8%. Program sustainability needs to be accelerated by making specific policies that are in line with sustainable development and can be followed up with measurable programs so that they can increase the ranking in the following years.

Abstract

This study evaluates pollution load, water quality status, biodegradability characteristics, and ecological pressure in the Sringin River, Semarang City, Central Java. Key parameters analyzed included Total Suspended Solids (TSS), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and lead (Pb), supported by measurements of discharge, pH, temperature, dissolved oxygen (DO), and salinity using purposive sampling across three river segments. The results show increasing pollution from upstream to downstream, with BOD ranging from 6.2 to 12.2 mg/L, COD from 302 to 327 mg/L, TSS up to 151 mg/L, and Pb concentrations reaching 7.31 mg/L—far exceeding the quality standard of 0.03 mg/L. Dissolved oxygen remained above 7 mg/L but exhibited spatial fluctuation, while the BOD/COD ratio (< 0.3–0.4) indicates the dominance of partially non-biodegradable waste that slows natural self-purification. Pb accumulation in water, sediments, and aquatic biota suggests potential ecological and human health risks through bioaccumulation and biomagnification. Overall, the Sringin River experiences chronic ecological pressure due to combined organic and inorganic pollution, emphasizing the need for source-based pollution control, continuous monitoring, and ecological risk–oriented water quality management to sustain aquatic ecosystem functions.
