Abstract

Analisis warna dapat digunakan untuk mengetahui karakteristik mutu dan tingkat kematangan produk pertanian, termasuk alpukat. Alpukat Mentega dengan tiga tingkat kematangan berbeda A1: kurang dari 80%, A2: 80-85%, dan A3: tingkat kematangan lebih dari 85% dikumpulkan dari Bandungan, Indonesia. Karakterisasi buah alpukat dilakukan dengan 33 buah sampel untuk setiap tingkat kematangan dengan bobot sekitar 366±16 g. Kehilangan massa dan dimensi (%), sifat warna (L*a*b*), dan kekerasan (kg.mm-2) dievaluasi. Hasil penelitian menunjukkan tingkat kematangan berpengaruh nyata terhadap susut massa, kekerasan, dan sifat warna (L* dan a*). Penyimpanan selama 10 hari pada suhu ruang untuk sampel A3 (tingkat kematangan lebih dari 85%) menunjukkan kehilangan massa tertinggi (4,77±2,31%), kehilangan dimensi (114,36±7,83% untuk panjang dan 22,79±15,78% untuk lebar), dan nilai kekerasan terendah (0,46±0,31 kg.mm-2). Hubungan antara warna kulit dan karakteristik mutu alpukat Mentega dikembangkan menggunakan data kekerasan buah dan indeks kematangan alpukat (AMI) dengan rumus F = -0,1116x-0,9692; MAPE = 21,74%. Data aktual dan estimasi kekerasan menunjukkan bahwa model cocok untuk menggambarkan kekerasan buah aktual di bawah kondisi percobaan yang sama.

Abstract

Burung pipit menjadi salah satu ancaman bagi tanaman padi di sawah bagi petani yang menggunakan sistem irigasi di Desa Wandasari, Kecamatan Bojonggambir, Tasikmalaya. Hasil penelitian menunjukkan bahwa serangan hama, termasuk burung pipit, dapat mengakibatkan penurunan produktivitas padi sebesar 50% hingga 80%. Petani telah mencoba berbagai cara untuk mengusir burung pipit, mulai dari berteriak-teriak, memasang sangkar perangkap, hingga metode seperti memasang kaleng dengan tali atau bahkan berburu burung pipit dengan senjata api. Namun, karena keterbatasan pengawasan sawah, seringkali petani tidak berhasil menghalau burung pipit, dan akibatnya tanaman padi mereka terancam. Salah satu solusi yang telah diimplementasikan adalah penggunaan teknologi gelombang ultrasonik untuk mengusir burung pipit tanpa membunuhnya. Teknologi ini terdiri dari perangkat elektronik yang menggunakan sensor PIR untuk mendeteksi kehadiran burung pipit. Mikrokontroler Arduino digunakan sebagai otak utama yang terhubung ke relay. Amplifier berfungsi untuk menghasilkan gelombang ultrasonik, dan lampu LDR digunakan sebagai indikator pergerakan burung. Perangkat ini ditenagai oleh panel surya dan baterai 12 volt yang dapat diisi ulang saat kondisi malam atau intensitas sinar matahari rendah. Perangkat ini dapat berputar mengikuti pergerakan burung pipit dan mengeluarkan gelombang ultrasonik pada frekuensi 25 - 34,5 KHz selama 30 menit, tergantung pada gerakan burung. Perangkat ini memiliki jangkauan deteksi maksimal hingga 15 meter. Penggunaan perangkat pengusir burung pipit ini berhasil mengurangi dampak burung pipit pada tanaman padi di sawah sebesar 95% dan meningkatkan hasil panen petani. Inisiatif penerapan teknologi ini diharapkan dapat diperluas dan dikembangkan di wilayah lain untuk manfaat yang lebih luas.

Abstract

Hygiene products commonly contain SLS (Sodium Lauryl Sulfate) which can trigger skin irritation or cause dandruff on the scalp. Through innovation and technological advancements, a 3-in-1 soap is planned to be studied to create a natural soap that is effective and contains natural ingredients that are beneficial for skin health. The aim of this research is to determine the physical and chemical characteristics of the 3-in-1 hygiene product based on sapindus (Sapindus rarak) and pineapple peel extract, and also to assess the potential microbial contamination in the 3-in-1 hygiene product. The research method used is the RAL (Randomized Complete Block Design) with 2 factors: sapindus concentration (A=15%, 22.5%, and 30%) and pineapple peel extract (B=9%, 18%, and 27%) with 3 replications. Testing parameters include physicochemical quality (viscosity, specific gravity, foam stability, and pH) as well as the inhibition ability against S. aureus and E. coli. The results show that variations in treatment have a significant effect on all test parameters except specific gravity. The best treatment was obtained by comparing data with SNI 4085:2017, resulting in treatment A2B2 with viscosity of 10,57±0,05de cp, specific gravity of 25.99±0.09 g/ml, foam stability of 71,27±0,25e %, and pH of 4,01±0,10c, with inhibition zone against E. coli of 5±0,00a mm and 6±1,41ab mm.

Abstract

Tefa (Teaching Factory) is a learning media developed to carry out production activities continuously.Tefa are developed by the Department of Agriculture to focus on Pineapple processing production activity such as  Pineapple Pie which is currently existing. The necessary effort to continue maintaing Tefa's existence and productivity is to formulate a Tefa development strategy. The method used to formulate Tefa's development strategy recommendations is started from Tefa’s current business analysis by looking at the Internal-External (IE) matrix. Followed by analysing internal and external factors from all actors involved in the supply chain. After the IFE-EFE matrix is compiled and assessed by experts, then a SWOT analysis will be carried out to obtain a list of strategy recommendations. Finally the priority order of strategies is determined by QSPM analysis. The results of the supply chain activity analysis show that the highest added value will be obtained by Tefa if it uses flow 2, namely buying raw materials directly from farmers. While the result of the priority recommendations for the development strategy is Tefa actively begins to compile and implement the 4P marketing mix marketing strategy.
