Abstract

Parabolic trough type solar collector is a potential heating device for use in a dryer. This instrument utilizes radiation or sunlight as a heat source. Generally, solar collector converts solar radiation energy in electromagnetic waves form into heat energy. In this research, a parabolic trough type solar collector had been made using an aluminum tape reflector which was coated with polyester as a protector. In this study, measurements of temperature and humidity in the absorber pipe were carried out, as well as the intensity of solar radiation and wind speed. Based on the reslut of measurement and data processing, it was found that the pattern of increasing the air and absorber temperature followed the pattern of solar radiation’s intensity. In other words, the temperature was directly proportional to change in the intensity of solar radiation. The highest air temperature in this experiment was 51.5 oC and the highest temperature of the absorber pipe was 56.6 oC. Moreover, the wind speed with a value above 0.6 m/s lowers the air temperature in the absorber. The increase in air temperature was inversely proportional to the value of the air humidity in the absorber.

Abstract

ABSTRAKIkan bandeng merupakan jenis ikan yang sangat digemari oleh masyarakat karena mempunyai kandungan gizi yang baik yakni kandungan protein tinggi. Ikan bandeng di Kampung Salok Lay sangat melimpah namun belum dilakukan pengolahan yang maksimal untuk meningkatkan nilai jualnya. Selain itu, kelompok tambak di Kampung Salok Lay kesulitan dalam menjual hasil panennya karena ukuran ikan yang di minta oleh pembeli dalam jumlah yang banyak tidak sama rata. Hal ini, disebabkan juga oleh minimnya bibit dengan kualitas bagus dan harga pakan yang tinggi. Ikan Bandeng hasil panen lebih banyak di jual ke pasar tradisional dengan harga relative murah sehingga sering kali mengakibatkan kerugian kepada para kelompok tambak ikan. Perlu dilakukan alternative pengolahan ikan bandeng, yaitu menjadi ikan bandeng presto. Dan membuat desain kemasan produk ikan bandeng agar mempunyai nilai jual yang cukup tinggi. Metode yang diterapkan pada kegiatan pengabdian kepada masyarakat (PkM) ini adalah memberikan sosialisasi dan pelatihan cara pengolahan ikan bandeng presto. Dari kegiatan ini masyarakat Salok Lay RT 09 sangat antusias mengikuti kegiatan ini terbukti dengan tingkat kehadiran masyarakat sejumlah 10 orang, yang merupakan pemilik tambak ikan bandeng. Kata kunci : ikan bandeng; tambak; presto ABSTRACTMilkfish is a type of fish that is very popular with the community because it has good nutritional content, namely high protein content. Milkfish in Kampung Salok Lay is abundant but has not been processed optimally to increase its selling value. In addition, the pond group in Kampung Salok Lay has difficulty selling their harvests because the size of fish demanded by buyers in large quantities is not the same. This is also due to the lack of good quality seeds and high feed prices. As a result, most harvested milkfish are sold to traditional markets at relatively low prices, which often results in losses for fish pond groups. Therefore, it is necessary to do alternative processing of milkfish to become presto milkfish. And make a packaging design for milkfish products, so they have a reasonably high selling value. The method applied to this community service activity (PkM) is to provide socialization and training on processing presto milkfish. The people of Salok Lay RT 09 were enthusiastic about participating in this activity, as evidenced by the presence of 10 who are owners of milkfish ponds. Keywords: milkfish; pond; presto

Abstract

Direct Current (DC) magnetron sputtering is one of the Physical Vapour Deposition (PVD) technique that use plasma as a medium. In this experiment, vacuum pumps, vacuum tubes (plasma reactor), capacitor, MOT transformers, HV bridge diodes, and regulator transformers is the main instrumen of DC magnetron sputtering. By ionizing the trapped gas inside the vacuum tube we created the plasma. The ionization process can be done by giving DC high voltage electricity to the trapped gas in the plasma reactor that formed plasma. DC high voltage electricity (at 800-1600 Volt) can be form using regulator transformers, MOT transformers, HV bridge diodes, and HV capacitor. Plasma’s are ignited with the distance between the electrodes which is 2, 4, 6, and 8 cm and two different vacuum pump. From the experiment we got plasma at 35 Volt on regulator transformers or 464 Volt that measure on the electrodes.

Abstract

The  high carbohydrate content  in  durian seed flour  (DSF) has the potential to be a source of food energy that can replace wheat flour in the world. DSF processing has an impact on color changes that affect  the quality of the product.  Therefore, the purpose of this study is to modify durian seeds to obtain the best properties of durian seed flour through the soaking process. The modification was carried out  in a 0.6%  (w/v)  solution of sodium metabisulfite at a temperature of 30 ºC with a drying  temperature of 50 ºC for 17 hours before grinding and sifting in a size of 80 mesh.   Treatment of immersion time variables in minutes (40, 60, 80, 100, 120) using the Complete Randomized Design (RAL) method with three attempts.  The flour is then being analyzed its physical  and chemical properties.  The best treatment was obtained at soaking time during 120 minutes which had an impact on changes in chemical and physical properties.  The test  results showed that the longer soaking time reduced the moisture content and ash content of durian seed flour, but partially improved the  other parameters tested.  The amount of DSA, DSM  and fat is less affected by soaking time. In conclusion, DSF has the potential to be used as a base for pastries or biscuits due to its low water and protein content.  In addition, based on the residual content of sulfite, the durian seed flour obtained in this study is safe for consumption in accordance with GSFA standards.

Abstract

Beberapa metode pengolahan air atau water treatment telah banyak dikembangkan untuk mengatasi cemaran. Salah satu metode yang dikembangkan dalam pengolahan air adalah metode paparan plasma. Metode ini membutuhkan listrik tegangan tinggi dan tidak menggunakan zat kimia aktif. Paparan plasma pada air dan udara dapat menghasilkan spesies gas reaktif berbasis oksigen dan nitrogen atau reactive oxygen nitrogen species (RONS) dan cahaya ultraviolet. Gas reaktif seperti ozon memiliki kemampuan untuk mengoksidasi, dan berpotensi menguraikan kandungan senyawa organik dalam air. Pada metode paparan plasma pada air, RONS yang terbentuk akibat interaksi plasma dengan udara di permukaan air sulit masuk kedalam air. Untuk mengoptimalkan RONS tersebut berdifusi atau masuk ke dalam air, dibutuhkan mekanisme aliran udara ke dalam air. Pada penelitian ini, dilakukan pemaparan air dengan plasma lucutan listrik yang dilengkapi aliran udara pada elektroda. Penelitian ini bertujuan untuk mempelajari pengaruh durasi paparan plasma terhadap perubahan endapan, keasaman (pH) dan Total Dissolve Solid (TDS) pada air. Secara umum metode yang telah dilakukan pada penelitian ini, yaitu: pembuatan sampel air (asam, basa, garam) serta penyiapan sampel air danau; proses pemaparan plasma lucutan listrik; pengukuran nilai pH, TDS dan endapan. Sampel air yang digunakan air destilasi, air danau, air garam (larutan NaCl 0,07 M), air asam (larutan CH_3 COOH 0,005 M) dan air basa (larutan KOH 0,013 M). Plasma lucutan listrik dibangkitkan menggunakan catu daya tegangan tinggi DC, dengan nilai tegangan sekitar 30 kV. Aliran udara pada elektroda dihasilkan oleh aerator berkapasitas 2,5 liter/menit. Hasil pengukuran pH pada sampel air yang telah dipapar plasma lucutan listrik menunjukkan penurunan nilai pH disemua sampel air. Laju penurunan pH tertinggi ada pada sampel air KOH dengan nilai 0.0014 pH/s.  Semakin lama durasi pemaparan plasma pada sampel air garam dan air danau menyebabkan nilai TDS sampel mengalami peningkatan dengan masing-masing nilai tertinggi 5000 ppm dan 634 ppm . Hasil pengukuran endapan pada sampel air danau menunjukkan jumlah endapan yang terbentuk cenderung meningkat seiring bertambahnya durasi paparan plasma. Berdasarkan hasil penelitian ini, metode plasma lucutan listrik dapat mempermudah terbentuknya endapan pada air keruh seperti air danau, namun paparan yang lama dapat menurunkan pH (air menjadi semakin asam) dan meningkatkan nilai TDS air tersebut.

Abstract

Silica is a material that is widely found in nature and is able to withstand corrosion attacks from corrosive environments. However, this natural material must be extracted to obtain high purity silica. Simple sol-gel method is used to solve the extraction problem (nano-silica with high purity). The natural materials used in this research come from organic materials, namely rice husks from the local area (Loa Kulu area). The main objective of this experiment is studying the effect concentration of HCl for crystalline size.  The synthesis of silica was carried out with the preparation of ashes, then mixed with NaOH 7M until a solution of sodium silicate was produced. Silicate sodium solution was pressed with HCl 2M to form a silica gel with pH 7, 5, and 3 then was dried to produce silica powder. Silica powder was then burned at a temperature of 1000°C to produce silica with a crystalline phase. Based on the experiment, silica powder before calcination has amorphous phase and at any pH variation, the crystallite size calculated with the Debye Scherrer approach does not show any change the crystallite size by the variation of the silica gel’s pH. In addition, silica powder calcinated at 1000°C has amorphous and cristobalite phases and showed changes in crystal size after calculated with Debye Scherrer’s approach.

Abstract

Ionic thermoelectric (i-TE) materials have gained significant attention for their potential to convert low-temperature thermal energy into electrical energy. In this study, gel electrolyte-based i-TE materials have been synthesized using carboxymethyl cellulose (CMC), glycerin and H3PO4 solution as electrolyte. Analysis of thermoelectric properties such as Seebeck coefficient and power factor of the gel electrolyte has been carried out. In this study, ionic conductivity and potential difference or output voltage of CMC/glycerin gel electrolyte were measured. The results of this study indicate that the ionic conductivity and output voltage of the CMC/glycerin sample increase with temperature, whereas the Seebeck coefficient and power factor tend to decrease as the temperature gradient between the hot and cold parts of the CMC/glycerin gel electrolyte sample increases. These findings suggest that the CMC/glycerin-based polymer gel electrolyte has potential for use in i-TE devices, particularly in applications where high power output is required.
