Abstract

Revitalisasi fungsi agama dianggap oleh sejumlah kalangan sebagai instrumen efektif untuk melawan kanker korupsi, selain pelaksanaan demokratisasi dan liberalisasi pasar. Sistem nilai, ajaran moral, dan dalamnya spiritualitas dalam agama dianggap menjadi antitesa bagi watak korup yang berkembang di tengah masyarakat kontemporer. Semakin tinggi tingkat religiusitas suatu masyarakat, level korupsi diharapkan semakin rendah. Mengaca kepada data Corruption Perception Index (CPI/IPK) kita justru akan menemukan kecenderungan feno­mena yang berbeda. Dalam konteks negara-negara Islam misalnya, tingginya pengaruh kepercayaan umat Muslim terhadap agama yang diimani­nya ternyata tidak berbanding lurus dengan komitmen pemberantasan korupsi. Fenomena ini patut dijadikan refleksi bersama untuk menemukan jawaban atas per­tanyaan klasik; mengapa praktik korupsi cenderung banal alias lumrah dalam tradisi masyarakat Muslim yang dianggap memegang teguh prinsip moral dan integritas dalam kehidupan bermasyarakat dan bernegara? Artikel ini akan mendiskusikan secara general tentang relasi agama dan korupsi, serta mengulasnya dengan meng­konteks­tualisasikan ke dalam pengalaman negara-negara Islam.***The revitalization of religion function—that some people think—is an effective instrument to fight the cancer of corruption and also the implementation of democratization and liberalization of the market. Value systems, moral teachings and spirituality in religion are considered to be opposite of the corruption characters growing in the contemporary society. The more religiosity of a society leads to the expectation for the lower corruption. However, according to the Corruption Perception Index (CPI) data, we will exactly find a tendency of paradoxical phenomena. For example, in the context of Islamic countries, the high of influence for the Muslims belief to their religion is not directly proportional to the commitment of the corruption eradication in the Muslim populized countries mostly. This phenomenon deserves to be shared reflection, to find the answers of classic questions; why does corruption tend becoming habit of Muslim community who are uphold moral principles and integrity in social life and state? It causes this article to discuss the relationship between religion and corruption in general, and also to elaborate it by dealing with the experience of Islamic countries.***Keywords: Islam, korupsi, good governance, demokratisasi

Abstract

The decreasing of yogurt drink quality will occur during storage. Stabilizer that usually used for maintaining the yogurt quality is a chemical compound namely carboxymethyl cellulose (CMC). Canna (Canna edulis Ker) potentially used as a natural stabilizer, which is a local Indonesian tuber with high starch content and antioxidative properties. The purpose of this study is to investigate the capability of Canna starch to replace the used of CMC based on the physicochemical and antioxidant activity of yogurt drink during cold storage. The complete randomized factorial design will be used with two factor. The first factor was Canna starch/CMC levels divided into 5 groups, T0 (0.2%CMC) as a control, T1 (0.15% CMC + 0.025% canna), T2 (0.1% CMC + 0.05% canna), T3 (0.05% CMC + 0.075% canna), and T4 (0.1% Canna), respectively. The second factor was the storage time of yogurt drink divided into four groups, 1, 7, 14 and 21 days, to determine the quality change during stored in the refrigerator at 4°C. Data obtained from the results of subsequent studies analyzed by GLM (General Linear Model) and followed by Duncan's multiple range test (DMRT). This study resulted that Canna starch has the capability as a natural stabilizer for producing functional yogurt drink with potential health benefits related to the high antioxidant activity. The combination of 0.1% CMC and 0.05% Canna starch addition on yogurt drink manufacture showed the best physicochemical quality

Abstract

ABSTRAKKedudukan media pembelajaran manipulatif atau yang disebut alat peraga merupakan bagian dari sarana yang wajib dimiliki oleh setiap satuan pendidikan. Sedangkan kedudukan alat peraga terkait dengan komponen metode mengajar merupakan salah satu upaya untuk meningkatkan proses interaksi guru dengan peserta didik (atau siswa) di lingkungan belajarnya. Hal ini dikarenakan obyek dalam pembelajaran matematika yang berupa fakta, konsep, prinsip dan skill/keterampilan merupakan benda pikiran yang sifatnya abstrak dan tidak dapat diamati dengan panca indera. Untuk mengatasi masalah tersebut, maka dalam mempelajari suatu obyek dalam pembelajaran matematika diperlukan pengalaman melalui benda-benda nyata (konkrit) yaitu alat peraga. Dalam usulan program pengabdian ini, alat peraga yang dikembangkan berbasis edutainment (pendidikan yang terintegrasi dalam hiburan) yaitu berupa permainan (games). Konsep ini digunakan dengan tujuan memudahkan anak untuk memahami konsep matematika dengan cara menyenangkan, terutama bagi anak berkebutuhan khusus. Keterampilan guru dalam membuat dan mendemonstrasikan (mengenalkan) alat peraga kepada siswa berkebutuhan khusus menjadi kunci utama keberhasilan siswa dalam memahami konsep matematika menjadi lebih mudah. Oleh karena itu, pelakanaan program pengabdian ini memfokuskan pada memberikan keterampilan pada guru SDLB dalam membuat hingga mendemonstrasikan alat peraga kepada siswanya, sehingga siswa SDLB mampu mengenal media pembelajaran manilpulatif matematika dengan baik. Dalam program pengabdian ini, media pembelajaran yang dibuat dalam pelatihan adalah media tower angka, dimana media ini dapat digunakan untuk anak tuna grahita dan tuna rungu. Pelatihan ini terdiri dari tiga sesi materi, yaitu materi pembuatan media pembelajaran matematika, materi penggunaan/ pengoperasian media pembelajaran matematika dan materi pendemonstrasian dalam pembelajaran.                                                                                                                 Kata Kunci: media pembelajaran matematika, manipulatif, anak berkebutuhan khusus, keterampilan, guru

Abstract

Cryptography is the science of maintaining or securing an information by scrambling or hiding information so that it is difficult to analyze. The algorithm used in this study is the AES 128 algorithm that has been changed using the grayscale image. The AES algorithm is a modern algorithm that replaces the DES algorithm, and is an algorithm that is chosen to secure a data / message because it is efficient and has strong security. In the process, the grayscale image key is divided into 16 blocks of pixels, pixels are operated on each block with XOR operations so that one character will be obtained for each block. From the XOR process of pixels in 16 blocks, 16 characters or 128 bits long will be obtained. The data used in this study are plain images in the form of grayscale images and keys in the form of grayscale images as well. Grayscale (plain image) images will be encrypted with an image key that is also a grayscale image. Initially, the key will be taken from a grayscale image by dividing 16 blocks to get a 128-bit long key, then generating the key with the key generator in the AES algorithm so that it will get 10 sub-keys. Then encryption is done with 10 subkeys that were obtained using the AES algorithm. The results of the encryption process will produce an encoded image or cipher image that does not contain information from the plain image. The results of this algorithm are fairly safe against attacks because they have varied and sensitive keys. Keywords: Cryptography, AES, Rijndael Algorithm, Grayscale

Abstract

Salted egg is a well-known traditional product, particularly in many Asian countries, where it is valued for its unique savory taste, extended shelf life, and convenience. Consumer demand for healthier, more appealing food has sparked interest in enriching salted eggs with natural ingredients. The purpose of this study was to analyze the effect of adding kaffir lime leaf powder (Citrus hystrix) and citronella leaf powder (Cymbopogon nardus) to salted eggs on pH, antioxidants, moisture and organoleptics. The research method used was experimental using a completely randomized design (CRD) with 6 treatments and 3 replications. The treatment of lime leaf powder and lemongrass leaf powder addition rates are 0%, 2.5%, 5%, 7.5%, 10% and 12.5%. The data was analyzed using Analysis of Variance (ANOVA), if there is a real influence it will be tested using the Duncan test. The results of the study showed a very significant difference (p < 0.01) on antioxidants and organoleptics, and significant difference (p < 0.05) on pH value. Meanwhile, the addition of kaffir lime leaf powder and citronella leaf powder to salted eggs showed no significant difference (p > 0.05) on moisture content. Average pH value 7.05-7.84; antioxidant 1.46- 10.85 %; moisture content 55.13- 67.87%; organoleptic aroma 3.44-4.02; taste 3.58-4.08. This score range reflects how the participants perceived the aroma and rated the taste of the salted eggs. The conclusion of this research is the best treatment with the addition of kaffir lime leaf powder  and citronella leaf powder as much as 12.5%.

Abstract

Marshmallow is one of the confectionery product that made from gelatin and sugar that have the weakness of lacking nutrients but favored by people of all ages. Bee pollen can be the one of natural addition that can enrich the nutrient in marshmallows. The aim of this study was to evaluate bee pollen addition with different concentrations reviewed from physicochemical and organoleptic test of marshmallows. Tresearch method used was a experimental using Complete Randomized Design (CRD) with 4 treatments and 5 replications. Four treatments were applied: P0 (without bee pollen addition), P1 (5%), P2 (10%), and P3 (15%). The study resulted significant differences (P<0.01) in water activity, texture, Lab color, ash content, reducing sugar, antioxidant activity, color, aroma, dan overall organoleptic acceptance, and no significant differences (P>0.05) in moisture content and organoleptic texture. The values resulted increased in moisture content (36.85-37.64%), color a* (0.14-3.38), color b* (25.39-33.27), ash content (0.806-2.404%), reducing sugar (0.372-6.677%), and decreased in antioxidant activity (92.96-503.92 mg/ml) and fluctuated in water activity (0.74-0.86), texture (0.68-1.16 N), and color L* (79.70-91.92). The results of the organoleptic test were still acceptable up to treatment P3. Overall, this study resulted the best results in treatment P3 with a bee pollen concentrations of 15% to increase the nutritional content of marshmallows.
