Abstract

Abstract: Analog rice is artificial rice made from carbohydrate sources to resemble rice. Taro kimpul is one of Indonesia's local foods rich in carbohydrates that have not been widely used and have functional properties to be used as a raw material for analog rice. In this study, the manufacture of analog rice also used functional ingredients (beets and dragon fruit peels) containing phytochemical beneficial compounds and binders (carboxymethyl cellulose/CMC and carrageenan). This research aimed to determine the functional characteristics of analog rice and was expected to produce analog rice with a low-calorie value. The research was conducted in two stages: analog rice was made with four formulations; and an analysis of the functional characteristics of analog rice was conducted. This research was done with descriptive analysis so that it could describe the effect of adding functional ingredients and binders to the characteristics of analog rice. Based on the decision-making method, the best treatment in this study was taro analog rice F1 with the use of 2% carrageenan and 32% beetroot. The functional characteristics of taro analog rice F1 are as follows: crude fiber 2.13%, calories 112.29 kcal/100g, total phenol 0.51 mg GAE/g, anthocyanin 56.77mg/100g, and antioxidant activity of 74.92%. The analog rice obtained had higher antioxidant activity, total phenol, anthocyanin, and lower calorific value compared to polished rice.Abstrak: Beras analog adalah beras tiruan yang dibuat dari sumber karbohidrat menyerupai beras.

Abstract: Aneuk Laot Lake becomes a source of livelihood for people who work as fishermen around the lake. This research was conducted in June 2020. The study aims to analyze the food habits, niche breadth, and niche overlap of tilapia (Oreochromis niloticus), mujair (Oreochromis mossambicus), and louhan (Cichlasoma trimaculatum) in Aneuk Laot Lake. The method used in this study is the survey method. Fishing is done with the use of ring trawls of 2 and 3 inches. Tilapia, Mujair, and Louhan fish that have been caught were dissected and their digestive organs were preserved using 10% NBF. The results showed that Tilapia (O. niloticus) are omnivorous with phytoplankton as their main food and an index of preponderance value of 54.72%, Mujair (O. mossambicus) are omnivorous with the main food in the form of phytoplankton and the index of preponderance value is 50.15%, and louhan (C. trimaculatum) is carnivorous with the main food in the form of small fish and the index of preponderance value is 99.35%. The value of the niche breadth of Tilapia is 2.89, Mujair is 2.66, and Louhan is 1.07. The niche overlap value of food between Tilapia and Mujair is 0.96, meaning that it has great potential to utilize the same type of food, whereas Louhan's niche overlap index with Nila and Mujair is 0.01, indicating that it has very little competition in using the same food.Abstrak: Danau Aneuk Laot menjadi sumber mata pencaharian bagi masyarakat yang berprofesi sebagai nelayan di sekitar danau.

Abstract

Abstract: All production activities will eventually produce waste, especially liquid waste. The nitrate ion (NO3-) is one of the substances in liquid waste that can have a significant impact on water systems and human health. Several methods can be used to treat the nitrate contained in the water, such as adsorption, phytoremediation, and wetland treatment. One of its methods was adsorption. The silica was modified with polymer due to its huge carbon chain. This research was focused on optimizing the ability of silica-based materials using PEG by physically coating them since PEG has a long carbon chain that could be transformed into a helix. In this research, the adsorbent will be prepared from modified silica gel with PEG 4000 by physical coating. Several parameters will be observed, including the effect of coating time, silica-PEG ratio, and PEG concentration. The capacity of silica-PEG to absorb NO3- is being studied. The characterization of functional group content in silica-PEG was carried out by Fourier Transform Infrared (FTIR). The study results show that the coating time was 10 minutes with the ratio of silica to PEG of 1:5, and the concentration of PEG used was 15%, indicating the optimum performance of silica-PEG when used as an absorbent, which achieved 84.44 % nitrate removal. An increase in the absorption capacity of silica-PEG demonstrates the ability of silica-PEG as a porous material. It was compared to silica gel without the PEG coating process, which was 9.09% to 84.44%.Abstrak: Semua kegiatan produksi pada akhirnya akan menghasilkan limbah, terutama limbah cair. Limbah cair biasanya akan bermuara di sungai dan berakhir di laut. Salah satu zat dalam limbah cair adalah ion nitrat (NO3-) yang mana dalam jumlah banyak dapat mengganggu sistem perairan dan kesehatan. Beberapa metode dapat digunakan untuk mengolah nitrat yang terkandung dalam air, seperti adsorpsi. Salah satunya dimodifikasi dengan polimer karena memiliki rantai karbon yang besar. Penelitian ini dikonsentrasikan untuk menyelidiki optimalisasi kemampuan silika dengan PEG dengan pelapisan fisik karena PEG memiliki rantai karbon panjang yang dapat bertransformasi menjadi heliks. Dalam penelitian ini, adsorben akan dibuat dari silika gel termodifikasi dengan PEG 4000 dengan pelapisan fisik. Beberapa parameter yang akan diamati antara lain pengaruh waktu pelapisan, rasio silika-PEG, konsentrasi PEG, dan temperatur pelapisan. Kinerja silika-PEG untuk menyerap NO3- diselidiki. Karakterisasi kandungan gugus fungsi pada silika-PEG dilakukan dengan Fourier Transform InfraRed (FTIR). Hasil penelitian menunjukkan bahwa waktu pelapisan adalah 10 menit dengan perbandingan silika dan PEG 1:5, dan konsentrasi PEG yang digunakan adalah 15%, menunjukkan kinerja silika-PEG yang optimum bila digunakan sebagai penyerap NO3-. Kemampuan silika-PEG sebagai bahan berpori dibuktikan dengan peningkatan kapasitas penyerapan silika-PEG dibandingkan silika gel tanpa proses pelapisan PEG.

Abstract

Abstract: Edible film have received considerable attention because of their advantages including their use as edible packaging material over synthetic films. This study aimed to characterize an edible film based on carrageenan and Syzygium cumini leaf extract (SCLE) as a natural antioxidant. The addition of SCLE was carried out with various concentrations of 0, 5, 10 and 15%. Characterization was carried out by measuring the physical properties, mechanical properties and antioxidant activities. The result showed that the presence of SCLE gave an increase in thickness and a decrease in solubility and water content compared to the edible film without the addition of SCLE. The addition of 5% SCLE resulted in a slight increase in tensile strength and a reduction in elongation at break. The edible films also showed an increase in antioxidant activity with the addition of SCLE where the highest antioxidant activity was at the addition of 15% SCLE. The incorporation of natural antioxidants in edible films can be a potential strategy to produce promising active packaging to extend product shelf life in the food packaging industry.Abstrak: Edible film telah mendapat banyak perhatian karena keuntungannya sebagai kemasan yang dapat dimakan  dibandingkan film sintetik. Tujuan dari penelitian ini adalah untuk mengkarakterisasi edible film berbasis karaginan dan ekstrak daun Syzygium cumini (SCLE) sebagai antioksidan alami. Penambahan SCLE dilakukan dengan variasi konsentrasi 0, 5, 10 dan 15%. Karakterisasi dilakukan dengan mengukur sifat fisika, sifat mekanik dan aktivitas antioksidannya. Hasil menunjukkan bahwa keberadaan SCLE memberikan peningkatan pada ketebalan dan penurunan pada kelarutan dan kadar air dibandingkan edibe film tanpa penambahan SCLE. Penambahan SCLE sebanyak 5% menghasilkan sedikit peningkatan pada kuat tarik dan pengurangan pada perpanjangan putus. Edible film juga menunjukkan peningkatan aktivitas antioksidan dengan penambahan SCLE dimana aktivitas antioksidan tertinggi pada penambahan 15% SCLE. Penggabungan antioksidan alami pada edible film dapat menjadi strategi potensial untuk menghasilkan kemasan aktif yang menjanjikan untuk memperpanjang umur simpan produk pada industri kemasan makanan.

Abstract

Abstract: Utilization of groundwater sources is still an alternative for people living in the coastal areas of Aceh Besar District. If the use of groundwater is carried out continuously, it will have a negative impact on the quality and quantity of groundwater. So the purpose of this study was to determine the distribution of groundwater salinity in the coastal areas of Aceh Besar District. The sample points were determined based on the random sampling method in grids. Sample testing for groundwater salinity was carried out directly in the field according to the planned location. The data obtained was inputted into Microsoft excel and mapping of groundwater salinity distribution using the Inverse Distance Weight (IDW) method with Argis software. A correlation test was performed with Pearson Product Moment.  Based on the measurement results, 20 sample points of high salinity were measured. The distribution of salinity values also has a relationship with coastal distance, where the distribution of salinity in general, the farther the groundwater is from the coast, the lower the salinity value, and the closer the groundwater to the coast, the higher the salinity.Abstrak: Pemanfaatan sumber air tanah masih menjadi alternatif bagi masyarakat yang tinggal di wilayah pesisir Kabupaten Aceh Besar. Jika pemanfaatan air tanah dilakukan secara terus-menerus akan berdampak negatif secara kualitas dan kuantitas air tanah. Sehingga tujuan penelitian ini adalah untuk mengetahui sebaran salinitas  air tanah di wilayah pesisir Kabupaten Aceh Besar. Titik sampel ditentukan berdasarkan metode random sampling in grids. Pengujian sampel untuk salinitas air tanah dilakukan langsung di lapangan sesuai dengan lokasi yang telah direncanakan. Data yang diperoleh diinput ke dalam Microsoft excel dan pemetaan distribusi salinitas air tanah menggunakan metode Inverse Distance Weight (IDW) dengan perangkat lunak Argis. Uji korelasi dilakukan dengan Pearson Product Moment. Berdasarkan hasil pengukuran, nilai salinitas yang tinggi terukur sebanyak 20 titik sampel. Nilai salinitas tinggi pada umumnya dipengaruhi oleh intrusi air asin terhadap air tawar. Faktor sebaran salinitas air tanah terjadi akibat intrusi, penggunaan lahan yang dekat dengan tambak dan muara sungai, faktor sebaran salinitas juga dipengaruhi oleh kepadatan penduduk. Sebaran nilai salinitas juga memiliki hubungan dengan jarak pantai, dimana sebaran salinitas secara umum, semakin jauh air tanah dengan jarak pantai maka nilai salinitasnya semakin rendah, dan semakin dekat air tanah dengan jarak pantai maka salinitasnya semakin tinggi.

Abstract

Abstract: Various purification techniques have been developed to improve the quality of local salt, especially the NaCl content of more than 94%. One of the binding materials used in salt purification is bentonite. This study aims to synthesize modified bentonite using hydrochloric acid (HCl) solution and measure the metal content of NaCl, Pb, Ca, and Mg using AAS. The synthesis of activated bentonite was carried out using the hydrolysis method using 0.1 M HCl (1:10). Bentonite was separated from the filtrate and dried at 110°C for 2 hours. Bentonite, which had been activated with HCl, was dried again at 170°C for four hours. Analytical methods such as XRD, FTIR, and SEM were used to characterize HCl-activated bentonite. The results of the analysis showed that the acid activation process did not change the basal spacing d001 on the bentonite diffractogram. FTIR analysis showed that there was a shift in the -OH stretching vibration towards a lower wave number and a decrease in the absorption intensity. The activation process will reduce the pore size and increase the surface area and porosity of the bentonite. The results of the AAS analysis showed that the NaCl content in the salt increased after the purification process using acid-activated bentonite, followed by a decrease in the metal content of Mg. Based on the results of the analysis, it can be concluded that HCl-activated bentonite is effectively used in the salt purification process to improve salt quality.Abstrak:Berbagai teknik pemurnian telah dikembangkan untuk meningkatkan kualitas garam lokal, khususnya kandungan NaCl besar dari 94%. Salah satu zat pengikat yang digunakan dalam pemurnian garam adalah bentonit. Penelitian ini bertujuan untuk mensintesis bentonit termodifikasi menggunakan larutan asam klorida (HCl), dan mengukur kadar logam NaCl, Pb, Ca, dan Mg menggunakan metode SSA. Sintesis bentonit teraktivasi dilakukan menggunakan metode hidrolisis menggunakan  0,1 M HCl (1:10).Bentonit dipisahkan dari filtrat dan dikeringkan pada suhu 110°C selama 2 jam. Bentonit yang telah diaktivasi dengan HCl dikeringkan kembali pada suhu 170°C selama empat jam. Metode analisis seperti XRD, FTIR, dan SEM digunakan untuk mengkarakterisasi bentonit teraktivasi HCl. Hasil analisis menunjukkan bahwa proses aktivasi asam tidak mengubah basal spacing d001 pada difraktogram bentonit. Analisis FTIR menunjukkan terjadi pergeseran vibrasi ulur -OH ke arah bilangan gelombang yang lebih rendah dan penurunan intensitas serapan. Proses aktivasi akan memperkecil ukuran pori dan memperbesar luas permukaan serta porositas pada bentonit. Hasil analisis SSA menunjukkan bahwa kandungan NaCl pada garam mengalami peningkatan setelah proses pemurnian menggunakan bentonit teraktivasi asam yang diikuti dengan penurunan kadar logam Mg. Berdasarkan hasil analisis dapat disimpulkan bahwa bentonit teraktivasi HCl efektif digunakan dalam proses pemurnian garam untuk meningkatkan kualitas garam.
