Judul: Formulasi Sedotan Bioplastik Heat-Resistant Berbasis Agar dan Polymer Blend
Abstrak: Sedotan plastik merupakan salah satu produk sekali pakai yang telah menjadi bagian dari gaya hidup masyarakat tetapi menimbulkan permasalahan pencemaran lingkungan. Sedotan bioplastik yang telah dikembangkan sebagai solusi alternatif memiliki sifat fisikokimia dan termal yang masih terbatas. Penelitian ini bertujuan menentukan formula sedotan bioplastik dengan karakteristik fisikokimia serta termal terbaik. Tahapan penelitian ini terdiri dari formulasi dan pencetakan bioplastik, formulasi dan pencetakan sedotan, serta penentuan formula terbaik berdasarkan analisis fisikokimia dan termal. Analisis yang dilakukan yaitu ketebalan, daya absorpsi air, mikrostruktur, sifat tarik, sudut kontak, gugus fungsi, dan stabilitas termal. Perbedaan polimer utama pada formula berpengaruh terhadap daya absorpsi air, kuat tarik, elongasi, serta sudut kontak. Sedotan SAP (agar, pati jagung, kalsium karbonat, sorbitol, beeswax, asam sitrat, akuades) sebagai formula terbaik memiliki warna putih kusam dengan tekstur permukaan yang halus dan homogen, berstruktur kokoh, serta dapat ditekuk hingga 90°. Hasil analisis menunjukkan bahwa formula SAP mempunyai ketebalan 0,68±0,12 mm, permukaan yang homogen, daya absorpsi air 135,51±2,83%, kuat tarik 73,33±6,01 MPa, elongasi 39,53±10,26%, serta gugus fungsi yang mengindikasikan adanya interaksi kimia antar bahan. Uji sudut kontak dengan nilai 105,53±2,46º mengindikasikan bahwa SAP bersifat hidrofobik. Thermogravimetric analysis menunjukkan bahwa sedotan SAP mulai terdegradasi secara signifikan pada suhu 200℃.

Judul: Characteristics of Chitosan-Agar Based Bioplastics with the Addition of Different Amounts of Sorbitol as a Plasticizer
Abstrak: Plastik telah menjadi salah satu penyumbang sampah terutama di lingkungan perairan. Penggunaan plastik sebagai kemasan telah menjadi gaya hidup di banyak negara yang memicu kebutuhan plastik yang cukup tinggi. Pembuatan bioplastik berbasis agar masih memiliki sifat fisik yang kurang baik seperti kaku dan kurang elastis. Penambahan material lain seperti kitosan dan sorbitol diharapkan dapat memperbaiki sifat bioplastik yang dihasilkan. Penelitian ini bertujuan untuk menentukan formula terbaik dari campuran kitosan dan agar sebagai bahan pembuatan bioplastik dengan jumlah plasticizer sorbitol yang berbeda serta mengetahui karakteristik sifat fisikokimia material bioplastik yang dihasilkan. Tahapan penelitian meliputi pencampuran kitosan, agar, dan sorbitol (0%, 1%, 1,25%, dan 1,5%), pencetakan bioplastik dan karakterisasi bioplastik. Karakterisasi bioplastik meliputi uji ketebalan, uji kuat tarik dan elongasi, daya serap air, analisis gugus fungsi dengan Fourier Transform Infra Red Spectroscopy, dan uji degradasi. Bioplastik dengan formula terbaik yaitu perlakuan 1,25% yang menghasilkan nilai ketebalan 0,096±0,004 mm, daya serap air 18,80±0,94%, kuat tarik 18,83±2,93 MPa, dan elongasi 95,89±12,62%. Waktu yang diperlukan bioplastik 1,25% untuk terdegradasi sempurna yaitu selama 20 hari., Plastic has become one of the contributors to waste, especially in the aquatic environment. The use of plastic as packaging has become a lifestyle in many countries which triggers a high demand for plastic. The manufacture of agar-based bioplastics still has poor physical properties such as stiffness and lack of elasticity. The addition of other materials such as chitosan and sorbitol are expected to improve the properties of the bioplastics produced. This study aims to determine the best formula for the mixture of chitosan and agar as a bioplastic material with different amounts of sorbitol plasticizer and to determine the characteristics of the physicochemical properties of the resulting bioplastic material. The research stages included mixing chitosan, agar, and sorbitol (0%, 1%, 1.25%, and 1.5%), bioplastic molding and bioplastic characterization. Bioplastic characterization includes thickness test, tensile strength and elongation test, water absorption, functional group analysis with Fourier Transform Infra Red Spectroscopy and degradation test. Bioplastics with the best formula was 1.25% treatment which produces a thickness value of 0.096±0.004 mm, water absorption of 18.80±0.94%, tensile strength of 18.83±2.93 MPa, and elongation of 95.89±12.62%. The time required for 1.25% bioplastic to degrade completely was 20 days.

Judul: Manajemen Pemeliharaan Kuda (Equus caballus) Untuk Upacara Kenegaraan Dan Sarana Kesenjataan Di Detasemen Kavaleri Berkuda (DenKavkud) TNI-AD Parongpong
Abstrak: Cavalry Horse Detachement (Denkavkud) Indonesian National Army-Cavalary Parongpong is one of the Indonesian military units that utilize the horse and train it as a means of purpose of formal state ceremony and armed forces. Skills possessed by the horse cavalry was the result of care management and specialized training provided by the trainer. Aspects of care management are breeding, feeding, and management. Horses that are kept in the Denkavkud, Parongpong are stallions, mares, foals, and military horses. Total populations of horses at Denkavkud are 183 horses. Besides commited horse training (remonte), Denkavkud also did breeding program to produce horses that can be trained and used as a military horse. There are some issues contained in Denkavkud, such as some of the nutrients needed by the horses not being met from feed given. One of these is crude protein and lysine. Lactation mares was crude protein and lysine deficiency. The number of death in 2010 is higher than previous years. Based on the number of horses that died from January until June 2010 is 11 horses. The average mortality was caused by colic. Colic is caused by excessive eating, excessive drinking during hot, moldy food, and even by investment roundworms. Animal welfare in Denkavkud can be enhanced by improvement of feed given and improving the health of livestock through improved sanitation.
