Abstract

HIDROLISIS POLISAKARIDA XILAN JERAMI MENGGUNAKAN LARUTAN ASAM KUAT UNTUK BAHAN DASAR PRODUKSI BIOETANOL ABSTRAKHidrolisis merupakan proses pemecahan polisakarida (gula kompleks) menjadi polimer yang lebih sederhana, mengingat syarat utama dari proses fermentasi untuk produksi bioetanol adalah gula monomer atau dimer. Polisakarida yang digunakan yakni hasil pretreatment dan ekstraksi jerami. Penggunaan cara kimiawi pada proses hidrolisis ini bertujuan untuk mendapatkan hasil yang optimum dengan waktu yang singkat. Metode penelitian yang digunakan adalah hidrolisis asam dengan membandingkan dua jenis larutan asam kuat yaitu asam sulfat (H2SO4) dan asam klorida (HCl) dengan konsentrasi masig-masing sebesar 0.5 N. Hidrolisis dilakukan dalam kondisi pada suhu 115 0C selama 60 menit pada tekanan 1 atm. Gula sederhana yang dihasilkan telah diuji dengan uji gula total, dengan hasil bahwa gula pereduksi diketahui dari selisih gula total pada kontrol tanpa perlakuan. Uji gula total dilakukan menggunakan metode Dubois, pengujian ini dilakukan pada hasil optimum dari hidrolisis yaitu asam klorida (HCl). Sampel yang diujikan yaitu, xilan (XI) dan kontrol (-) xilan (k-x). Analisis gula total menghasilkan sebanyak 2.906 mg/L untuk XI, sebanyak 728 mg/L untuk (k-x) dengan hasil bahwa  perolehan gula pereduksi sebesar 2.124 mg/L. Selisih hasil gula total yang diperoleh antara perlakuan dan kontrol mengindikasikan bahwa proses hidrolisis berhasil mendapatkan gula pereduksi.Kata kunci: gula kompleks, hidrolisis asam, gula sederhana, gula pereduksi dan gula total. HYDROLYSIS OF POLYCOXARIDA XYLANE STRAW USING STRONG ACID ACID SOLUTION FOR BASIC MATERIALS OF BIOETANOL PRODUCTION ABSTRACTHydrolysis is the process of breaking polysaccharides (sugar complexes) into simpler polymers, considering the main requirements of the fermentation process for bioethanol production are monomeric or dimeric sugars. The polysaccharides used are the results of pretreatment and extraction of straw. The use of chemical methods in the hydrolysis process aims to obtain optimum results with a short time. The research method used is acid hydrolysis by comparing two types of strong acid solutions namely sulfuric acid (H2SO4) and hydrochloric acid (HCl) with a concentration of each of 0.5 N. Hydrolysis is carried out under conditions at a temperature of 115 0C for 60 minutes at a pressure of 1 atm. The simple sugar produced was tested with a total sugar test, the result of the reducing sugar was known from the total sugar difference in the control without treatment. The total sugar test was carried out using the Dubois method, this test was carried out on the optimum results of hydrolysis, namely hydrochloric acid (HCl). The sample tested were, xylan (XI) and control (-) xylan (k-x). Analysis of total sugar yielded as much as 2,906 mg / L for XI, as much as 728 mg / L for (k-x) the result of the acquisition of reducing sugars was 2,124 mg / L.

Abstract

Doyomulyo is a village located in Lamongan residents , most of the population's livelihood as a farmer. The village is also known have a source of groundwater. Even during a drought these sources remain abundant. Doyomulyo Village is indeed included in the drought-prone map during the rainy season like now. However, Donomulyo Village still has a source of raw water that is used for daily needs. One of them is near the Donomulyo Village hall mosque, but the water source is adjacent to the mosque's bathroom septic tank. So the laboratory results show the results of DO, TDS, COD, BOD, Total Coliform and E. Coli which do not meet the standards. And there is the desire of the people of Doyomulyo Village, Kembangbahu District, Lamongan Regency to produce groundwater into bottled drinking water (AMDK). So that Unisla through community service activities wants to improve the quality of Doyomulya village water sources so that they become drinking water that is ready for consumption. In Community Service (PKM) activities, the team used a groundwater treatment method with a modified IPAM prototype. Based on the results of groundwater characteristics obtained, the design of equipment for the drinking water treatment unit in Doyomulyo, Lamongan Regency requires that the filter media for the filter tube are activated carbon, silica sand and manganese zeolite used to remove dissolved particles above 50 µ in size and can also reduce concentration of iron and organic matter contained. Community Service Program (PKM) activities by FIKES UNISLA in Doyomulya Village have resulted in a planning program for drinking water treatment to increase the demand for drinking water for residents of Doyomulya Village and its surroundings.

Abstract

A biopore infiltration hole can handle organic household waste for the composting process. It can be optimized by adding an Effective Microorganism 4 (EM4) activator. This study aims to determine the effect of EM4 addition on water adsorption time, compost weight, and compost quality, according to SNI 19-7030-2004. Lamongan Islamic University's Laboratory of Environmental and Health Science determined the compost test's nutrient content. A cylindrical hole was drilled into the ground using a BIH drill with a diameter of 10 cm and a depth of 50, 75, and 100 cm, with a distance of 100 cm for each hole. The materials used in this study included domestic organic waste, leaves explicitly, and kitchen waste, a 50-ml liquid EM4 "Agriculture" activator diluted with 100 ml of distilled water, and 10 grams of granulated sugar.  The experiment was conducted for 15, 30, and 45 days. To measure the water absorption time, a 2x1x1 m barrier is needed to accommodate 2 m3. The difference in BIH diameter can affect the infiltration rate at the Biopores Infiltration Hole (BIH). The measurement's highest water absorption occurred at the beginning of the 15th day. The addition of EM4 affects the decomposition process and can increase the water absorption rate for 45 days. The EM4 additions affect the decomposition process's timing. Additionally, the addition of EM4 impacts the nutrients in the compost. The addition of EM4 increased the value of C-organic, nitrogen, phosphorus, and total potassium in the BIH compost.

Abstract

DHF (Dengue hemorrhagic fever) is a tropical endemic disease in Indonesia with a fluctuating trend in Lamongan. The main factor under control is the larval breeding habitat. This study aimed to determine the relationship between the characteristics of the water medium and the density of Aedes sp. mosquito larvae in Karanggeneng Village, Lamongan Regency. We conducted this quantitative study using a cross-sectional observational method on a sample of 80 houses in Karanggeneng Village, employing a straightforward random sampling technique. We recorded the data collection in the observation sheet and analyzed it with a chi-square test. The results showed that 37 houses were positive for Aedes sp. larvae based on HI (DF = 6), CI (DF = 6), and BI (DF = 7), so Karanggeneng Village has a high mosquito larval density. There is a significant relationship between water media and the presence of Aedes sp. mosquito larvae. The relationship between pH (p-value = 0.000), temperature (p-value = 0.000), and TDS (p-value = 0.000) is significant. We recommend regularly draining the water container weekly to prevent mosquito larvae from using it as a habitat.

Abstract

The Final Disposal Site (TPA) of Tambakrigadung Village, Lamongan Regency, implements a semi-sanitary landfill system in which waste processing still piles up piles of waste with soil for a certain period, causing a foul odor due to the leachate that collects. Leachate that is not managed correctly is feared to flow into reservoirs as irrigation and productive land that is used by local communities for rice fields or ponds around the Tambakrigadung TPA so that it can disrupt workers, reduce the quality and yield of rice fields, and affect the development of pond fish around the Tambakrigadung landfill. This research aims to test the quality of reservoir water, which refers to the leachate water quality standards of PermenLHK RI No. P.59 Tahun 2016. It analyzes the influence of leachate on reservoir water around Tambakrigadung. The method used in this research is grab sampling. Analysis of pH, BOD, COD, and TSS parameters using simple linear regression quantitative analysis. Quantitative parameter analysis shows that TPA Tambakrigadung leachate influences the pH and TSS parameters of reservoir water in Tikung District, Lamongan Regency, which is indicated by a significance value of <0.05. The analysis of heavy metal parameters shows that the leachate does not meet quality standards, with a total N of 187.7 ppm and cadmium of 0.15 ppm. The mercury parameter meets quality standards, namely 0.00065 ppm. Meanwhile, heavy metal parameters in reservoir water have met quality standards based on PP No. 22 of 2021.
