Abstract

Limbah cair batik di Solo sebagian besar dibuang langsung ke perairan tanpa diolah terlebih dahulu dan menyebabkan pencemaran air. Kandungan logam berat di dalam limbah cair batik dapat memicu efek genotoksik seperti pembentukan mikronukleus. Lemna minor berpotensi sebagai antimutagen dan mencegah pembentukan mikronukleus karena mengandung senyawa aktif seperti karoten dan asam amino. Penelitian ini bertujuan untuk mengetahui ekogenotoksisitas limbah cair batik dan efek antimutagenik Lemna minor terhadap eritrosit ikan nila. Penelitian dilakukan di Laboratorium Biologi UMS dengan pemaparan limbah cair batik 0ppm/L, 2500 ppm/L, 5000 ppm/L dan 7500 ppm/L terhadap 2 kelompok ikan nila dengan diet pelet dan Lemna minor. Hasil penelitian menunjukkan bahwa paparan limbah cair batik memicu pembentukan mikronukleus dengan frekwensi tertinggi pada konsentrasi paparan 7500 ppm/L. Lemna minor juga terbukti memiliki potensi antimutagenik karena mampu menekan frekwensi mikronukleus lebih rendah dibandingkan diet pelet.

Abstract

This program is carried out on Small and Medium Enterprises (SME) Suka Rasa and SME Sendang Rasa in Toroh District, Grobogan Regency. Both SMEs have the same characteristics of business and products, namely tempe chips and banana chips. The weakness of this SMEs is the packaging of products and ways of marketing that are very simple. Their behavior of business has not shown the attitudes of an entrepreneur, so the performance of SMEs is still low. Making product innovation was the aims of this community service program, for improving the knowledge and ability of entrepreneurship orientation of SMEs. The method used to develop an entrepreneurial orientation in this activity is using training and product innovation practices. The success of this activity was measured through perceptions of innovation and product sales performance. The result of this activity was shown a big change on the behavior of SMEs, that is becoming more entrepreneur oriented, such as: 1) SMEs have made innovation by experimenting the products of chips into various flavor variants, such as saltiness, barbeque flavor, and cheese flavor; 2) SMEs have been able to recognize the risks faced when innovating products; 3) SMEs can able to map competitors and market potential. The packaging design and P-IRT licenses on products produced by SMEs were an additional output for this program.

Abstract

The Sekar Lepen Keprabon River is one of the tributaries polluted by domestic waste. This study aims to determine the water quality of the Sekar Lepen Keprabon River before and after filtering using SPZ (coconut fiber, banana fronds, zeolite stone) and SPA (coconut fiber, banana fronds, coconut shell charcoal) filter media. This experiment uses SPZ and SPA filter media to purify water that is applied directly to the river. The methods used were primary and secondary data collection. The data obtained were analyzed using a descriptive quantitative approach and the effectiveness of each parameter was calculated. The results of this study indicate that the water quality before and after filtering with SPZ filter media obtained a fixed temperature value, pH increased, COD and TSS increased, and TDS decreased. Water quality before and after going through the SPA filter media obtained a fixed value in temperature, pH increased, COD and TSS decreased, and TDS increased. SPZ filter media in the water filtration process is more effective in increasing pH parameters and reducing TDS parameters in river water. In contrast, SPA filter media in the water filtration process is more effective in reducing COD and TSS parameters in river water.

Abstract

Dug well is a water source that is located relatively close to the ground surface so it is prone to pollution. This research aims to analyze the effect pollution source distance, construction and behavior of dug well users on total coliform content in Karangturi Village. Data collection was carried out by examining samples of dug well water in the laboratory, observing and measuring well construction, and using questionnaires to measure the behavior of well users. The research results show that 23 (95.8%) wells have a total coliform >0 MPN/100ml and 1 (4.2%) well have a total coliform content of 0 MPN/100ml. Simultaneously (p value=0.106) the variable distance to the pollutant source and partially (p value= 0.998) each livestock pen and septic tank variable do not have a significant influence on the total coliform content. Simultaneous well construction (p value= 0.489) and partially (p value= 0.999) of each well construction variable did not have a significant effect on the total coliform content. The behavioral variable simultaneously (p value= 0.346) and partially the knowledge variable (p value= 1.000), the attitude variable (p value= 0.999), and the attitude variable (p value= 0.999) did not have a significant effect on the total coliform content.
