Abstract

One of the industries that need attention is the woven sarong industry. This industry produces liquid waste resulting from the coloring process. Indiscriminate disposal of waste will have a detrimental impact on the environment. Therefore, it is necessary to treat the waste first. The purpose of this study was to reduce the levels of COD and TSS in the colored liquid waste of the weaving sarong industry. This research uses the adsorption method using the adsorbent Zeolite activated by sulfuric acid. The concentration of sulfuric acid used was 2.5 N. The lowest COD removal percentage with a zeolite mass of 1 gram with a time of 60 minutes was 30.98% and the highest percent COD removal with a zeolite mass of 5 grams with a time of 180 minutes was 59.61% . The lowest percentage of TSS removal with a zeolite mass of 1 gram with a time of 60 minutes was 74.16% and the highest percentage of TSS removal with a zeolite mass of 5 grams with a time of 180 minutes was 94.05%.

Abstract

Refined sugar is sugar that is produced from raw sugar through a refined processto remove impurities and molasses attached to Raw sugar. The process that will beused in the manufacture of refined sugar from raw sugar with carbonationpurification is divided into seven stages, namely: affination process, clarificationprocess, filtration process, decolorization process, evaporation process,crystallization process, drying process. The plant is planned to operate 300 daysper year with a capacity of 100,000 tons per year. The factory is planned to beestablished in Sambas Regency, West Kalimantan. From the results of theeconomic analysis obtained: Internal Rate Of Return (IRR) of 66%, Pay Out Time(POT) of 3.3 years, Break Even Point (BEP) of 36%. Based on the technical andeconomic analysis that has been carried out, it is feasible to establish a refinedsugar factory from raw sugar

Abstract

Cooking oil is a basic need of sicety which has the main content oftriglycerides. Tryglicerides function of fry food. The use of cooking oil continuously can reduce the quality of cooking oil. There are several attempts to improve the acid number and perokxide value in cooking oil. One of the efforts is providing an adsorbent in the form of kepok banana peels (Musa paradisiaca L.) using cooking oil. Kepok banana peel contain cellulose which acts as an adsorbent. This study used H3PO4 as an activator and NaOH as ad delignification in manufacturing kepok banan peel biosorbent. The research method includes the preparation of the biosorbent, the delignification  process, the activation  of the biosorbent with an activator, and the application of the biosorbent to used cooking oil. The method used is the adsorption method. The adsorption method used variable perecentage of the kepok banana peel mass : 5%, 10%, 15%, 20%, 25% (m/m), and adsorption method contact times were 60, 120, 180, and 240 minutes. The analyzes tested were the acid number. The acid number value of used cooking oil decreased with the addition of the mass of the biosorbent and the length of contact time. The optimum result obtained after treatment on the acid number value were 6.507 mg KOH/gr with a variable mass of biosorben of 25% at a concatct time of 240 minutes.

Abstract

Kebutuhan energi yang semakin meningkat mengakibatkan energi fosil menjadi semakin terbatas. Oleh karena itu dibutuhkan energi-energi terbarukan sebagai alternatif untuk pemenuhan kebutuhan tersebut. Pollard yang selama ini lebih cenderung dimanfaatkan secara langsung sebagai pakan ternak, ternyata memiliki manfaat lain sebagai bahan baku pembuatan bio-etanol yang merupakan salah satu energi terbarukan. Kandungan pati pada pollard dapat dipecah menjadi glukosa dengan menggunakan metode hidrolisis dengan katalis asam. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan katalis asam HCl dalam konsentrasi tertentu serta pengaruh dalam waktu reaksi yang digunakan dalam hidrolisis. Pada percobaan ini, bahan baku yang digunakan adalah pollard gandum yang dihidrolisa pada suhu 95°C dengan menggunakan variabel konsentrasi HCl 0,1; 0,3; 0,5N dan waktu reaksi hidrolisis selama 20, 30, 40, 50, 60, dan 70 menit. Sampel kemudian disaring untuk diambil filtratnya yang kemudian dilakukan analisa kadar glukosanya menggunakan alat Sugar Spektro Polarimeter. Sebelum didanalisa, dilakukan pengukuran panjang gelombang optimum dengan menggunakan standar glukosa 10%;  15%; 20%; dan 25% hingga didapatkan panjang gelombang optimum 545nm. Hasil %glukosa tertinggi (optimum) yang didapatkan pada penelitian ini adalah pada waktu hidrolisis 70 menit dengan menggunakan konsentrasi HCl 0,5N yaitu sebanyak 9,17% untuk setiap 5 gram pollard.Kata kunci : polard; hidrolisis; Sugar Spektro Polarimeter; optimum.

Abstract

Lapindo mud waste is hot mud from PT. Lapindo Brantas allegedly contains hazardous materials. Utilization of Lapindo mud waste must be carried out with several tests. Testing on the characteristics of the waste using the Toxicit Characteristic Leadching Procedure (TCLP) test. This research was conducted on a laboratory scale by varying the composition of cement, fine aggregate and Lapindo mud ((1:2:10), (1:3:10), (1:3:9) which were used as bricks and will be tested for absorption. brick brick gravity test, brick surface friction test The results of this study are the average compressive strength of bricks using Lapindo mud with a mixture composition of 10% mud decreased by 18.09 Kg/cm², the composition of the mixture 7.5% mud, namely 18.57 Kg/cm², and 5% mix composition, which is 20.94 Kg/cm², can be categorized as B4 quality bricks (Used for non-weather protected walls), with a standard strength of 21 kg/cm². Meanwhile, the absorption test of all brick compositions meets the requirements SNI is based on SNI 03-0349-1989 regarding concrete bricks (brick), the maximum air absorption rate requirement is 25%.Keywords: Brick, Lapindo Mud, Absorption Test

Abstract

Tofu liquid waste is a white liquid with a thick texture derived from unused tofu production. Tofu liquid waste contains nitrogen, phosphorus, potassium, and protein, which are easily fermentable. It will pollute the environment and cause a bad smell if it is directly thrown away without prior processing. Therefore, tofu liquid waste was processed into organic liquid fertilizer. The purpose of this study was to determine the effect of fermentation time and sugar ratio on the levels of N, P, K The manufacture of liquid fertilizer involves a fermentation process by adding Yakult and EM-4 because both contain lactobacillus bacteria which can help the fermentation process. The sugar and coconut water were also added in a ratio of 1:0.075, 1:0.125, and 1:0.25. The process of liquid waste fermentation was carried out for 5 days, 10 days, 15 days, and 20 days. Fertilizers were tested using the Kjeldahl method for nitrogen (N) levels, spectrophotometry to determine phosphorus (P2O5) levels, and AAS (atomic absorption spectroscopy) for potassium (K2O) levels. The best levels of N, P, and K were produced from tofu waste with a fermentation process for 10 days by 0.662%, 1.133%, and 1.239%, respectively.

Abstract

Research on the manufacture of bioplastics from bran is one of the efforts todevelop the development of environmentally friendly plastics because they can bedecomposed by microorganisms. In addition, this study also seeks to reduceenvironmental pollution due to the disposal of rice mill waste. The research wasconducted by mixing rice bran with water, sulfuric acid and sorbitol in variousvariations of the ratio of sorbitol and bran 1:10; 2:10; 3:10; 4:10 and 5:10 (v:b).Furthermore, chitosan was added as a reinforcement with variations in theaddition of chitosan with bran, namely 4:10; 6:10; 8:10; 10:10 and 12:10 thenprinted and analyzed for dance strength, swelling and surface morphology. Thetest results showed the highest tensile strength value in the ratio of sorbitol andbran 5:10 and chitosan bran 10:10 with the highest tensile strength value of 64.27MPa and 25% swelling value. Surface morphology shows an uneven and hollowsurface.
