Abstract

Indonesia merupakan salah satu produsen karet terbesar di dunia yang kini menempati posisi kedua setelah Thailand. Lateks yang diperoleh dari pohon karet dengan cara penyadapan selanjutnya di olah untuk berbagai keperluan. Rendahnya mutu bahan olah karet di Indonesia mendorong para peneliti untuk dapat meningkatkan kualitasnya. Salah satunya dengan memanfaatkan berbagai bahan untuk menggumpalkan lateks sebagai proses penanganan setelah penyadapan. Penelitian tentang pemanfaatan bahan-bahan seperti ekstrak buah-buahan yang memiliki pH asam, nira aren ataupun penggunaan limbah cair pabrik tahu yang juga sebagai bentuk penanganan limbah telah dilakukan. Hasil dari beberapa penelitian yang dilakukan menunjukkan bahwa bahan-bahan tersebut dapat digunakan sebagai penggumpal lateks.

Abstract

This research is aimed to determine the level of vitamin C in the mango Gadung which stored as long as 0 days; 1 day; 2 days; and 3 days. It is used iodimetric titration. Standard iodine solution used as titrant while starch as the indicator. Determination of raw normality iodine standardization carried out by titration of iodine with sodium thiosulphate solution primer. Normality primary sodium thiosulphate solution (0.0125 N) are determined through standardized sodium thiosulphate with potassium dichromate. Levels of vitamin C in the fruit is determined by linear regression analysis were made based on the graph of the vitamin C levels versus volume of iodine standard solution which used in the titration. The curve gives the equation as following: y = 413.8 x – 1.238. Levels of vitamin C of mango Gadung which has varied retention time as follows: 0.26% (0 days); 0.22% (1 day); 0.20% (2 days); and 0.16% (3 days).

Abstract

The rapid growth of ICT (Information and CommunicationTechnology), which changed the whole aspect of human life, such as the way people think, behave, communicate, work and support themselves. This change had a positive impact on the improvement of the efficiency of information and communication needs. So that the use of IT in all areas of life provides a significant advantage. Utilization of Information and Communication Technology (ICT) in the institution of Higher Education requires planning and management are mature, both in infrastructure, human resources and in terms of users, so that the use of ICT / ICT not only to improve the effectiveness, efficiency and productivity, but also can improve competitiveness (competitive adventages) in the era of globalization ini.Metode used in this study is a Echosystem consisting of three (3) stages of development that the ICT development by UNSECO, iT development, and the development model Zen Framework Smart Campus (TeSCA). It is hoped this method can be a strategic step in the utilization of and basis for the advancement of the ICT development of STT-Payakumbuh campus in the future

Abstract

Greywater reuse is considered as one solution in solving water scarcity problem in the world because it is less contagious and less polluting to environment than the entire municipal wastewater. Greywater is easier to treat and reuse it. One possibility to treat greywater is using constructed wetland followed by an advanced oxidation process such as photocatalytic oxidation. This process removes organic materials in waste water by oxidation via hydroxyl radicals. There was discussion about the effects of the solution inorganic matrix such as borate on the photocatalytic oxidation. Borate a common constituent of greywater was reported to inhibit photocatalytic oxidation. This research tried to determine the effect of boric acid on photocatalytic oxidation spiked with boric acid in concentration of 5 to 200 mg/L using aqueous TetraEGDME solutions. It was found that there is no inhibition of photocatalytic oxidation process when boric acid is present and pH is acidic (about 4-5).

Abstract

Even though the water is supplied from Water Treatment Plant 24 hours a day, some consumers of Tirta Daroy Water Supply Company receive water in their taps intermittently. This condition leads to several reported pipe breaks and coliforms presence, as well. Tirta Daroy conducts a quality control activity so called Pamkor on regular basis. This study is conducted to analyse data obtained from this activity during 2014, with the focus on the total coliforms for total 161 sampling connections. The result demonstrates that the coliforms presence is encouraged by the low chlorine residual and intermittent supply. Additional finding shows these two conditions occur mainly at the areas which have long distance to the water treatment plant.

Abstract

Supervision is a series of activities ranging from planning to monitoring results to complete the follow-up to the recommendations contained in the Report of Examination (LHP), which aims to see the commitment of the leadership of the examination results and performance improvement work units (SKPD). Inspectorate is one element that has the task of internal supervision within the Ministry. Inspectorate in recording the results of monitoring internally is still done manually, from the issuance of task orders, recording examination report (LHP) and the follow-up examination (TLHP) is often contained errors and were often late, so the inspector trouble to report the findings of disciplinary violations performed by employees each SKPD. To overcome the delays and errors LHP and TLHP would require an information system monitoring using methods Design System Research Method (DSRM), which consists of six (6) steps, namely the identification of problems, setting goals, designing architecture in client server and system design using UML , case studies, evaluation and communication. With this system is expected to help finance a part in issuing the warrant task quickly, and the administration can make the results of the examination report (LHP) in accordance with the code of the findings and recommendations of code that has been assigned the CPC to be followed up by the Inspector.

Abstract

Penelitian ini merupakan kelanjutan dari penelitian sebelumnya. Penelitian sebelumnya telah berhasil mengukur variabel suhu, kelembaban, dan radiasi surya pada titik pengukuran 07o13’42,5’’ LS dan 109o17’13,2’’ BT di ketinggian 1264 m dpl. Variabel yang akan dihitung dalam penelitian ini adalah evapotranspirasi. Dalam perhitungan evapotranspirasi memerlukan berbagai data dari pengukuran sebelumnya dan data dari klimatologi. Selain itu, nilai kecepatan angin juga diukur untuk mengetahui pengaruhnya terhadap produktivitas buah stroberi. Penelitian ini bertujuan untuk mengetahui pengaruh kecepatan angin dan evapotranspirasi terhadap kualitas buah stroberi. Kecepatan angin diukur secara langsung dengan alat Anemometer dengan rentang waktu 1 jam selama 24 jam. Sedangkan nilai evapotranspirasi dihitung dengan metode Penman menggunakan data-data pendukung yang telah diukur dan diketahui pada penelitian sebelumnya. Selanjutnya, dimodelkan nilai kecepatan angin terhadap waktu serta nilai evapotranspirasi terhadap waktu sebelum dan setelah interpolasi menggunakan Matlab dalam bentuk kurva 2D. Interpolasi digunakan untuk menentukan data-data yang belum terukur diantara data terukur. Nilai kecepatan angin maksimum yang diperoleh adalah 6,9 m/s, sedangkan evapotranspirasi maksimum 12,3 mm/hari dan minimum 9,2 mm/hari. Kecepatan angin memegang peranan penting dalam proses evapotranspirasi. Laju evapotranspirasi sebanding dengan kecepatan angin. Semakin tinggi kecepatan angin maka semakin tinggi nilai evapotranspirasi. Nilai kecepatan angin dan evapotranspirasi berpengaruh terhadap tinggi rendahnya produktivitas buah stroberi di daerah tersebut.
