Abstract

Kota Surabaya banyak mengalami perkembangan dibidang transportasi dan industri. Perkembangan ini menyebabkan meningkatnya emisi CO2. Penelitian ini bertujuan untuk menentukan kebutuhan ruang terbuka hijau yang dikeluarkan tiap-tiap area khusus di Kota Surabaya. Penelitian dilakukan dengan pendekatan metode perhitungan ruang terbuka hijau berdasarkan total emisi karbon dioksida yang dikeluarkan tiap-tiap area di sektor transportasi dan industri. Hasil penelitian menunjukkan bahwa sebaran emisi total CO2 di Surabaya Utara adalah 30.500,07 ton CO2/bulan dengan luas ruang terbuka hijau kira-kira 6,16 km2. Surabaya Timur sebaran emisi total CO2 adalah 115.653,46 ton CO2/bulan dengan luas ruang terbuka hijau kira-kira 23,24 km2. Untuk Surabaya Pusat, total emisi CO2 adalah 23.256,46 ton CO2/bulan luas ruang terbuka hijau kira-kira 4,75km2. Surabaya Utara memiliki total emisi CO2 adalah 865.709,04 ton CO2/bulan dengan luas ruang terbuka hijau kira-kira 14,54  km2. Sedangkan di Surabaya Barat, total emisi CO2 adalah 89.203,81 tonCO2/bulan dengan luas ruang terbuka hijau kira-kira 17,73 km2. Jadi kebutuhan ruang terbuka hijau di Surabaya Timur lebih besar dibandingkan dengan area lain karena memiliki total emisi CO2 yang tinggi.

Abstract

The search for alternative ingredients as natural sweeteners needs to be done. The sweeteners circulating in the market are synthetic sweeteners with no nutritional value and harm health. This research aims to produce a safe sweetener in the form of glucose syrup, which can be used as an alternative to artificial sweeteners through enzymatic reactions, and to find out the suitable reaction conditions to produce glucose syrup with the highest levels in several combinations of pH and temperature. Mango seed core is a source of carbohydrates that can be used as glucose syrup. The average starch content of 1940.1 grams of wet mango core is 10.09%. The starch was hydrolyzed with alpha-amylase and glucoamylase. It is biocatalysts through liquefaction stages (pH 5 and 6) and saccharification (temperature variables 55oCand 60oC).

Abstract

Cigarette butt waste can be used for biopesticides for environmentally friendly agricultural activities. Biopesticides cigarette can be produced by conducting a maceration extraction test using polar, non-polar, and semi-polar compounds and conducting a Mass Spectrometer Chromatography (GC-MS) test. This study aims to determine the effectiveness of bio-pesticide based on tobacco extract from cigarette butt waste for maize (Zea mays L.)". The highest yield value was the ethanol sample of 1.208%, compared to the N-hexane sample of 0.25% and the DCM sample of 0.6%. For the comparison of solvents used were 500 ml of ethanol, 250 ml of N-hexane, and 250 ml for DCM as well. After conducting the GC-MS test, the compounds obtained are alkaloid compounds, phenolic compounds, sesquiterpenoid compounds, and terpenoid compounds, each of which has benefits as a pest control or deterrent to plants. For the effectiveness test results on Corn (Zea mays L.), there was no intensity of pest attack on the ethanol sample, N-hexane sample, and DCM sample. In contrast, there was a pest attack intensity of 0.3% for the control sample. Therefore, the Biopesticides studied are similar to synthetic pesticides because they can eradicate pests and make growth effective faster.

Abstract

The Kebon Kongok waste disposal sites (WDS), Suka Makmur Village, is the final waste disposal site for Mataram City and West Lombok because Mataram City does not have a WDS. The condition of the WDS has exceeded its capacity. Suka Makmur Village is a village close to the Kebon Kongok WDS. This research was conducted in Suka Makmur Village to know groundwater quality with Smell, Taste, TDS, pH, BOD, COD, Ammonia (NH3N), and Total Coliform. The method used to determine the quality of groundwater is by using the Pollution Index Method. In determining the sampling technique, the purposive sampling technique is used, a determination technique with certain considerations. The results showed that the results of the analysis of raw water samples with the parameters Odor, Taste, Total Dissolved Solid, pH, BOD, COD, Ammonia (NH3N), and Total Coliform. The results obtained from the three sample points that exceeded the Water Quality Standard threshold were only the Total Coliform parameter, sample 1 was 230 mg/l, sample 2 was 91 mg/l, and sample 3 was 230 mg/l based on the Regulation of the Minister of Health of the Republic of Indonesia Number 32 2017 concerning Environmental Health Quality Standards and Water Health Requirements for Sanitation Hygiene, Swimming Pools, Solus Per Aqua, and Public Baths. Based on the results of data analysis using the Pollution Index Method (IP), sample one was 3.14, sample two was 1.68, and sample three was 3.13. These results indicate that the condition of the water is included in the Light Polluted category based on the Decree of the State Minister for the Environment Number 115 of 2003 concerning Water Quality Status, the Pollution Index value with an IP score of 1.1 - 5.0 is intended for class I water.
