Abstract

Indonesia memiliki lahan mangrove seluas 4,255 juta ha, termasuk yang terluas di dunia. Salah satu species yang banyak tumbuh di lahan mangrove adalah Rhizophora mucronata. Potensi tanaman mangrove di Bontang sebagai bahan baku pewarna alami cukup memadai. Luas tanam 2.935 ha menempati luasan sekitar 70% dari lahan yang tersedia. Luasan tersebut, terdapat sekitar 3 juta pohon jenis ini bila dianggap jarak tanam 2 m x 2 m, dengan anggapan bahwa setiap tahun satu batang pohon spesies ini menghasilkan 50 kg buah dan 50% buah tersebut dipergunakan untuk pembibitan maka masih tersedia sebanyak 75.000 ton buah sebagai bahan baku pewarna alami. Apabila perolehan proses ini sebesar 5% maka berpotensi diperoleh pewarna alami sebanyak 3.750 ton. Pada penelitian ini pengambilan zat warna alami dari buah mangrove spesies Rhizopora mucronata dilakukan dengan proses ekstraksi menggunakan pelarut air pada perbandingan massa bahan terhadap pelarut 1 : 10, suhu 100 °C selama 60 menit. Zat warna tersebut kemudian dipekatkan dengan proses evaporasi hingga volume tinggal 30%. Selanjutnya ekstrak dimanfaatkan untuk pewarnaan pada kain batik. Pada penelitian ini dipelajari pengaruh jumlah pencelupan : 5 kali, 7 kali, dan 10 kali terhadap hasil pewarnaan pada kain. Selain itu dipelajari juga pengaruh larutan fixer terhadap hasil pewarnaan pada kain. Larutan fixeryang digunakan pada percobaan ini yaitu tawas, kapur tohor dan tunjung. Untuk kain yang dicelupkan pada fixer tawas, memberikan warna yang lebih muda. Pencelupan zat warna dengan fixer kapur tohor memberikan warna coklat, sesuai warna asli ekstrak buah mangrove dan fixer dengan tunjung memberikan warna kehitaman.

Abstract

Penggunaan zat warna alami sekarang sudah mulai ditinggalkan karena adanya zat warna sintetis yang  praktis dalam penggunaanya, serta mempunyai warna yang  mencolok dan lebih seragam, mudah diaplikasikan. Dalam penggunaannya zat warna sintesis berbahaya bagi kesehatan dan lingkungan karena mengandung racun berupa logam berat, sehingga mulai dilakukan alternative penggatinya yaitu dengan cara megembangkan zat warna alami dari sumber-sumber hayati seperti buah mangrove spesies rhizopora mucronata/stylosa, kulit kayu mahoni, dan kulit kayu ting, tetapi zat warna alami ini ada kendala dalam pengaplikasiannya terutama pada batik. Untuk menanggulangi masalah tersebut diatas maka dibuat alat ekstraktor dan evaporator yang menghasilkan zat warna alami dalam bentuk konsentrat tinggi. Untuk menghasilkan konsentrat tinggi zat warna alami dari sumber hayati (mangrove spesies rhizopora mucronata/stylosa, kulit mahoni, dan kulit kayu tingi  diperlukan alat ekstraktor-evaporator. Spesifikasi alat ekstraktor-evaporator terdiri atas tangki berdiameter 20 cm dan tinggi 40 cm, peralatan ini diaplikasikan di mitra pertama dan pewarnaan di mitra kedua, Pada kegiatan yang dilakukan bagi mitra pertama adalah membuat zat warna alami dengan menggunakan alat ekstraktor-evaporator, sedangkan mitra kedua mengaplikasikan zat warna alami yang dihasilkan oleh mitra pertama. Kata Kunci:  batik, ekstraktor-eveporator,  zat warna alami

Abstract

Konsumsi karbon aktif di Indonesia semakin meningkat seiring dengan meningkatnya penggunaan karbon aktif dalam bidang industri. Mangrove atau yang sering dikenal sebagai pohon bakau di Indonesia merupakan tanaman jenis Rhizopora yang dapat berfungsi sebagai penyaring udara panas dari laut serta penyerap gas karbon di udara. Setiap tahun hutan mangrove dapat menyerap 42 juta ton karbon di udara atau setara dengan emisi gas karbon dari 25 juta mobil. Oleh karena itu, mangrove diproses menjadi karbon aktif agar bisa dimanfaatkan. Bagian dari mangrove yang digunakan untuk pembuatan karbon aktif yaitu buahnya. Pembuatan karbon aktif terdiri dari 2 tahap yaitu proses aktivasi dan proses karbonisasi. Proses aktivasi terbagi menjadi dua, yaitu aktivasi fisika dan kimia. Pada penelitian ini akan dibuat karbon aktif dari buah mangrove menggunakan metode aktivasi kimia, dengan kalium hidroksida (KOH) sebagai aktivatornya.  Sedangkan proses karbonisasi menggunakan 2 proses yaitu proses karbonisasi menggunakan furnace. Pada proses karbonisasi menggunakan furnace, bahan baku yang berupa buah mangrove diaktivasi menggunakan aktivator larutan KOH dengan variasi konsentrasi 0,5 M; 1 M; 1,5 M; 2 M; dan 2,5 M. Proses aktivasi bahan baku ini dilakukan selama 24 jam. Didapatkan luas permukaan karbon aktif optimum diperoleh pada saat konsentrasi KOH 0,5 M dengan luas permukaan 18,089 m2/g. Dengan jumlah bahan baku awal sebesar 750 gr  didapatkan produk karbon aktif sebesar 273 gr dan yield arang sebesar 36,4% dengan nilai laju konsumsi bahan bakar adalah 2,326 kg gas LPG/kg karbon aktif. Kata kunci: furnace, karbon aktif, mangrove

Abstract

Technological advance leads the natural dyes to be eroded by the synthetic one. Synthetic colorant has advantages of salient, more uniform color and more practical use. Meanwhile, the disadvantage of it is much metal content harmful to the environment. The natural colorant is colorant (pigment) derived from plant, animal or mineral sources. The advantage of natural dyes is that it is more environment-friendly because it is not poisonous and safe for health. The disadvantage of it is storage difficulty. When natural dyes in liquid form is stored too long, it will be decomposed easily. For that reason, it should be stored in powder form.The method used to get natural dyes was extraction with a batch manner. The extraction was carried out with basic material-to-solvent ratios of 1:10, 1:7, and 1:5. The basic materials used were mangrove spesies rhizopora stylosa, Soga Tingi, and Indigofera. The best extract was obtained with a ratio of 1:5 for all basic materials. The powder was prepared by feeding the extracting solvent into a spray dryer so that the natural colorant powder was obtained. The application of colorant powder was used at 1 gram/100 ml, 2 gram/100 ml, 2 gram/100 ml, 4 gram/100 ml, and 5 gram/100 ml. The immersing with natural colorant was conducted in 2 conditions: extract and powder are immersing were carried out 5 times with each submerging of 15 minutes and dried. Then, fixation (color-locking) was done to batik. The fixer employed was tunjung (changing the color of batik into the darker one), alum (maintaining the batik’s color), and lime (change batik color into the brighter one). The fixated batik cloth was then examined for its fading against washing using launder meter and against rubbing using crock meter. The result of the examination was analyzed using a staining scale and greyscale. The examination using the staining scale was divided into 2: wet and dry rubbings. From the result of the wet and dry rubbing test, it was obtained the best result with tingi colorant, alum fixer solution, and powder condition. Meanwhile, on the greyscale, it was obtained the best result with tingi colorant, alum fixer, and powder condition. So, it could be concluded that the optimum application of powder to batik cloth was 4 gram/100 ml water and 5 times immersing. The best result of fading resistance against washing and rubbing was tingi with alum fixer and in powder condition.Keywords – extraction, spray dryer, fixation, launderometer, and crockmeter

Abstract

Synthetic dyes are very practical to use and can lead to a striking color on the products. However, synthetic dye effluent may pollute the environment. For this reason, currently natural dyes have been used again for coloring. In order to ease the use of natural dyes, the liquid form of the dyes is dried into powder. In the present study, natural dyes extracted from kesumba seeds were dried using a spray dryer to form a powder. The Kesumba dye was extracted in an alkaline solutions of NaOH and Ca(OH)2. Drying was carried out with a feed having an average rate of 0.13 ml/sec at a temperature of 70°C. Meanwhile, dryer temperature was 120°C. Experimental results showed that extraction using NaOH solution offered better results than that using Ca(OH)2 solution. The extraction using NaOH solution was optimum at NaOH concentration of 0.4 M, temperature of 90°C and duration of 180 min. With this condition, the resulting powder was 19.6 g/L extract solution.

Abstract

One of the causes of environmental pollution is liquid waste generated by industries, especially the printing industry. PT Macanan Jaya Cemerlang is one of the printing industries producing liquid waste that does not meet the quality standards. The purpose of this research is to optimize the performance of Bioky bacteria using the Super Small Vessel in the wastewater treatment plant at PT X Klaten. Treatment involves testing variables such as residence time and bacteria quantity's impact on TSS, MBAS, COD, BOD, pH, and ORP.The study employs anaerobic treatment with observed variables: residence time of 1; 2; and 3 days, and bacteria quantity of 2.4; 3.2; and 4 liters. Samples from each variable are then analyzed for pH, ORP, and TSS. COD, BOD, and MBAS are tested after obtaining the best TSS results from each variable.The research results indicate that longer residence time and increased bacteria quantity lead to greater reduction in TSS, COD, BOD, and MBAS, while pH approaches neutrality. Optimal conditions occur at a 3-day residence time with 4,0 liters of bacteria, resulting in a reduction of TSS, COD, BOD, and MBAS against the inlet by 99.75%, 95.47%, 94.84%, and 26.72%. Although the treated waste doesn't meet the established standards, it effectively reduces the pollution levels in PT X's wastewater. Keywords:Anaerobic, Efficiency, Printing Industry Liquid Waste, Super Small Vessel

Abstract

The effect of molasses addition as a binder in the manufacturing of cow dung bio-pellets on their characteristics and combustion kinetics have been studied. The bio-pellets characterization included the physical and mechanical properties as well as the proximate analysis and calorific values. Thermogravimetric analysis (TGA) was carried out using a macro-TGA apparatus under a non-isothermal conditions and an oxidative atmosphere to study the thermal decomposition characteristics. Then, the first order Coast and Redfern method was used to determined the kinetic parameters of bio-pellets combustion. It was found that the ash content of bio-pellets were tended to decreased, while the volatile matter and fixed carbon were tended to increase with the addition of molasses. Nevertheless, the density, the axial compressive strength and the calorific values of bindered bio-pellets were decreased due to the higher amounts of water in the raw mixtures. Thermogravimetric analysis provided an information that the combustions of cow dung bio-pellets took place in three stages of decompositions The bindered bio-pellet began to decompose at lower temperatures than the binderless bio-pellet with a higher weight loss percentage. According to the comprehensive combustion characteristic index (S), the combustion performance of both binderless and bindered bio-pellets were similar. The addition of molasses as a binder tended to reduce the ignition temperature and activation energy for all stages of bio-pellets combustion. Keywords:Bio-pellet, Characterization, Cow Dung, Combustion Kinetics, Molasses
