There are various types of encryption that can be used, for example MD5 and SHA-256. However, using MD5 or SHA-256 alone is not safe enough because it can be solved by using a brute force attack. The method of working is very simple is to try all possible combinations. This study aims to develop MD5 and SHA256 collaboration methods. Encryption is applied to the user's password on the web login system. Simulation results can be tested by measuring resistance to brute force attacks and the value of the avalanche effect (AE). From the results of the tests carried out by using attack software, the results of the application are quite safe from brute force attacks. From the AE test obtained the result with an AE value of 71% which means that the encoding result is good enough.

Namun penggunaan MD5 saja atau SHA-256 saja tidak cukup aman karena dapat dipecahkan dengan menggunakan serangan brute force. Cara kerja metode sangat sederhana yaitu dengan mencoba semua kombinasi yang mungkin. Penelitian ini bertujuan untuk mengembangkan metode kolaborasi dari MD5 dan SHA-256. Enkripsi diterapkan pada password pengguna pada sistem login web. Hasil simulasi dapat diuji dengan mengukur ketahanan terhadap serangan brute force dan besar nilai avalanche effect (AE). Dari hasil pengujian yang dilakukan yaitu dengan menggunakan software attack hasil penyandian cukup aman dari serangan brute force. Dari pengujian AE diperoleh hasil dengan nilai AE sebesar 71% yang artinya hasil penyandian cukup baik.Kata kunci-Enkripsi, MD5, SHA-256, brute force, avalanche effect

<p class="Abstrak"><span lang="IN">Pengenalan huruf vokal bagi anak usia dini harus diperkenalkan sejak dini karena huruf vokal berfungsi untuk merangkai huruf dari kumpulan konsonan yang dijadikan suatu perkataan. Komputer grafis telah berdampak signifikan pada banyak bidang salah satunya animasi komputer. Animasi komputer dapat diimplemantasikan bagi anak untuk belajar karena dalam masa perkembangannya anak memiliki kecenderungan meniru dan mengamati sehingga memudahkan anak dalam menerima materi. Penelitian ini bertujuan untuk merancang dan mengetahui kelayakan animasi 3D pada media pembelajaran mengenal huruf vokal. Metode penelitian menggunakan model pengembangan waterfall meliputi tahapan pra produksi, produksi dan pasca produksi. Tahap pra produksi, (a) penentuan ide dan cerita; (b) desain karakter; (c) <em>storyboard</em>; (d) perekaman suara. Tahap produksi, (a) <em>modeling</em>; (b) <em>texturing</em>; (c) <em>rigging</em>; (d) <em>animating</em>; (e) <em>lighting</em>; (f) <em>camera operation</em>; (g) <em>rendering</em>. Tahap pasca produksi, (a) <em>final editing</em>; (b) hasil <em>video</em> animasi. Media animasi 3D mengenal huruf vokal dikategorikan layak setelah dilakukan validasi oleh 4 ahli media. Hal ini dibuktikan dalam pengujian pertama media didapatkan hasil rata-rata 81% yang berada pada kategori layak dengan catatan revisi sesuai saran. Pengujian kedua setelah media direvisi didapatkan hasil rata-rata 86,5%  yang berada pada kategori sangat layak.</span></p><p class="Abstrak" align="center"><span lang="IN"> </span></p><p class="Abstrak"><em><strong>Abstract</strong></em></p><p class="Abstrak"><em><em>The recognition of vowels for early childhood needs to be introduced early because the vowels function to string the letters of the consonant groups that are used as words. Based on the observation in KB Syiarul IslamTegal that the learning media know the vowels still use a simple props that is a vocal board attached to the class wall. This makes the child easily saturated and uninterested. In addition there is no media learning in the form of 3D animation. Anticipating these constraints, new learning media is needed using 3D animation. 3D animation can be implanted for the child to learn because in its development period the child has a tendency to emulate and observe so as to facilitate the child in receiving material. In general, this research aims to design and know the feasibility of visual elements (images, writings) and 3D animations on the media learning to know the vocal letters. The research method uses waterfall development model according to M. Suyanto (2006) which includes pre production stage, production and post production. Pre-production stage, (a) determination of ideas and stories; (b) Character design; (c) Storyboard; (d) Voice recording. Production stage, (a) modeling; (b) texturing; (c) Rigging; (d) Animating; (e) Lighting; (f) Camera operation; (g) Rendering. Post-production stage, (a) final editing; (b) The result of animated video. 3D animation Media know the vowels categorized worthy with the assessment of some aspects such as the aspect of image quality, sound quality, media content, objects and characters, background, animation techniques, storyline, and the impression of the video done validation by 4 Media experts. This is evidenced in the first test of the media obtained an average result of 81% which is in decent category with revision notes as per suggestion. The second Test after the revised media obtained an average yield of 86.5% which is in very decent category</em></em></p>

Pesticide sprayer tools that are widely used by farmers are still using hands or fossil fuel machines, so they are still classified as traditional and ineffective methods. Some of the weaknesses of the traditional method include less practical, fossil fuels that will run out and the impact on the environment. Solar energy from the sun can be a solution to these problems. Solar panels are devices used to convert sunlight into electrical energy. In this study, a monocrystalline 30W solar panel was used as a tool used to capture sunlight. By utilizing solar power as an energy source sprayer and pump so that it can take advantage of the hand pressing the lever and refilling it manually. In addition, preferring solar power over fossil fuel engines can reduce the use of fossil fuels and further strengthen renewable energy that will not run out and is environmentally friendly. In this study, solar panels were installed above the head to maximize the capture of sunlight and also protect the head from the heat of the sun. The results showed that the battery energy required to spray the difference in battery percentage from 10 liters to 6 liters of liquid volume was 4% and from 6 liters to 2 liters of liquid volume was 6%.

Tujuan kegiatan ini adalah untuk memperkenalkan teknologi pangan kepada ibu-ibu PKK RT03/RW03, Kelurahan Ngijo, Kecamatan Gunungpati, Semarang dengan memanfaatkan biji Durian (Durio zibethinus) dan biji Rambutan (Nephelium lappaceum) sebagai keripik. Target luaran yang diharapkan antara lain masyarakat dapat berwirausaha sehingga kesejahteraan keluarga dapat ditingkatkan. Hasil dari program pengabdian masyarakat yang telah dilakukan ini adalah sebagai berikut: aspek penerapan iptek produk pangan dipandang sangat efektif untuk membangun kemandirian masyarakat yang berbasis potensi lokal yakni pemanfaatan biji durian dan biji rambutan, dan aspek manfaat yang dihasilkan dari program ini sangat besar yaitu meningkatkan kesadaran masyarakat untuk memanfaatkan potensi pohon Durian dan Rambutan terutama bijinya untuk dibuat menjadi keripik, meningkatnya pengetahuan dan keterampilan masyarakat bidang pengolahan biji durian dan rambutan untuk dibuat keripik serta menumbuhkan motivasi berwirausaha khususnya di RT03/RW03, Kelurahan Ngijo, Kecamatan Gunungpati, Semarang.
