Abstract

Energi terbarukan yang ramah lingkungan merupakan solusi untuk menangani penggunaan energi yang berasal dari fosil. Energi terbarukan dapat berasal dari berbagai macam limbah, seperti limbah arang kayu alaban dan sekam padi. Keduanya merupakan limbah yang jarang sekali untuk dimanfaatkan lebih lanjut untuk mendapatkan nilai ekonomis yang tinggi. Hal ini dikarenakan belum banyak informasi yang beredar di masyarakat dalam hal pemanfaatannya lebih lanjut. Maka dari itu dilakukan penelitian untuk mengetahui bagaimana pengaruh variasi komposisi dan jenis perekat (tapioka dan sagu) terhadap sifat fisik briket (kadar air (water content), kadar abu (ash content), kadar zat terbang (volatile matter), kadar karbon terikat (fixed carbon) dan nilai kalor) pada briket limbah arang kayu alaban dan sekam padi. Terdapat lima variasi komposisi dengan perbandingan limbah arang kayu alaban dan sekam padi yaitu 90% : 10%, 70% : 30%, 50% : 50%, 30% : 70%, 10% : 90%. Menggunakan perekat yang terbuat dari tapioka dan sagu. Hasil penelitian menunjukkan peningkatan limbah arang kayu alaban dan dengan perekat sagu menghasilkan sifat fisik terbaik karena kadar air, abu, dan zat terbangnya rendah sedangkan kadar karbon terikat dan nilai kalornya tinggi. Berdasarkan SNI 01-6235-2000 didapatkan briket terbaik yaitu menggunakan komposisi limbah arang kayu alaban dan sekam padi sebesar 90% : 10% dengan perekat sagu menghasilkan kadar air sebesar 0.54%, kadar abu 4.70%, kadar zat terbang 42.02%, kadar karbon terikat 52.73% dan nilai kalor 5828 kal/gr.

Abstract

Itik Alabio (Anas Plathycus Borneo) berkembang di daerah Alabio Kabupaten Hulu Sungai Utara, Kalimantan Selatan dengan populasi itik pada tahun 2006 tercatat 3.487.002 ekor. Selama ini itik alabio hanya dimanfaatkan untuk daging dan telur, padahal bagian bulu unggas yang satu ini juga bisa dimanfaatkan sebagai bahan baku komposit karena sifatnya yang relatif kuat dan elastis. Untuk meningkatkan kualitas komposit, 10% bulu bebek dikombinasikan dengan 90% Serat Purun Tikus (Eleocharis Dulcis) sehingga menjadi komposit Hybrid. Bulu Itik komposit Hibrida dan Serat Purun Tikus di alkalisasi selama 10, 20, 30, 40, 50, dan 60 menit. Penelitian ini menggunakan metode uji eksperimental dan uji statistik ANOVA-One Way. Dari hasil penelitian diketahui bahwa waktu alkalisasi mempengaruhi nilai kekuatan sifat mekanik. Nilai paling optimal kekuatan tarik dan lentur dicapai pada waktu perendaman 20 menit. Yaitu sebesar 257,24 Mpa untuk kekuatan tarik dan kekuatan lenturnya sebesar 4,37 Mpa. Dalam komposit yang diperkuat serat dengan alkalisasi NaOH 5%, ikatan antara serat dan resin menjadi sempurna. Namun, semakin lama waktu alkalisasi, hemiselulosa, lignin dan pektin secara bertahap hilang sama sekali, kekuatan serat alami akan berkurang karena kumpulan mikrofibril yang membentuk serat yang disatukan oleh lignin dan pektin akan terpisah, sehingga serat hanya akan menjadi serat halus yang dipisahkan satu per satu sama lain.

Abstract

Pondok Pesantren Mahad Arrahman telah memanfaatkan energi terbarukan berupa sel surya untuk mengurangi pemakaian energi listrik, dan juga berfungsi sebagai energi cadangan ketika terjadinya pemadaman listrik. Namun, kendala lain muncul pada pemanfaatan energi sel surya ini, yaitu daya yang terpasang masih tidak mampu mencukupi kebutuhan pondok pesantren akan listrik. Penurunan performa ketika proses charging di siang hari yang terasa lebih lambat, dibandingkan waktu menjelang siang. Salah satu penyebabnya adalah ketika temperatur meningkat terjadi penurunan performa sel surya. Untuk itu diperlukan tambahan energi listrik berupa panel surya beserta instalasinya dengan teknologi berpendingin air. Kegiatan pengabdian masyarakat ini meliputi perancangan alat teknologi sel surya berpendingin air yang diharapkan dapat membantu mengatasi permasalahan di Pondok Pesantren Mahad Arrahman. Luaran kegiatan ini adalah berupa pemahaman dan transfer keterampilan teknologi sel surya berpendingin air dan Alat yang terdiri dari Sel Surya, Pompa air DC, Pipa Instalasi jalur air, Saklar, Kontroler, Inventer, dan Baterai. Manfaat dari kegiatan ini adalah terjadinya penambahan daya listrik menggunakan energy tenaga surya dan diharapkan terjadinya penurunan temperature setelah dipasang teknologi pendingin air sehingga terjadi peningkatan performa sel surya.

Abstract

South Kalimantan Province is the habitat for a type of plant known as Purun Tikus. This plant is traditionally used for handicrafts and serves as a habitat for Alabio ducks. Sodium hydroxide (NaOH) is an alkaline chemical compound that effectively removes and cleans residues in fibers. Therefore, this study investigates the composite materials reinforced with duck hair and Purun Tikus using an immersion alkalization method with NaOH. The objective of this research is to determine the effects of alkalization on a hybrid mixture of duck hair and Purun Tikus with a polyester matrix on wear and hardness properties, and to examine the influence of voids on perforated pores. The wear test was performed according to ASTM G99-04, and the hardness test followed the ASTM D-785 standard. Samples were prepared using the hand lay-up method with a composition of 78% polyester, 2% catalyst, and 20% reinforcement with a volume ratio of (10%:90%). The alkalization treatment times were set at 10, 20, 30, 40, 50, and 60 minutes using a 5% NaOH solution. The results indicated that the highest wear value was observed at the 10-minute alkalization time, while the lowest wear value was noted at the 60-minute alkalization time. Conversely, the highest hardness value was obtained at the 60-minute alkalization time, and the lowest at the 10-minute alkalization time. Therefore, alkalization time significantly affects the wear, hardness, and void properties of the composite materials.
