Abstract

Ikan rucah adalah ikan-ikan kecil yang ikut tertangkap nelayan selain ikan konsumsi. Ikan rucah memiliki potensi sebagai sumber protein hewani pakan ternak dan ikan. Ikan rucah selama ini belum termanfaatkan secara optimal, oleh karena itu Tim Pengabdian melakukan kegiatan penerapan mesin pembuat tepung ikan rucah. Tepung ikan rucah diharapkan dapat dimanfaatkan sebagai bahan pembuatan pakan teknak dan ikan tawar; sehingga ikan rucah dimanfaatkan secara optimal dan nilai ekonominya dapat meningkat. Metode pengabdian ini adalah dengan menerapkan mesin pembuat tepung ikan hasil rancang bangun Jurusan Ilmu Keteknikan Pertanian, Fakultas Pertanian, Universitas Lampung. Pengabdian ini juga menyampaikan wawasan dan pengetahuan tentang aspek-aspek dasar pengoperasian mesin penepung, perawatan dan pemanfaatan tepung ikan. Kegiatan penerapan mesin penepung berlajan dengan baik, proses pembuatan tepung ikan rucah dapat dilakukan dengan lebih mudah dan kapasitasnya mencapai 100-300 kg/hari. Mitra pengabdian mampu menyerap pengetahuan dan penjelasan yang disampaikan oleh Tim pengabdian sehingga mereka mampu mengoperasikan mesin penepung, melakukan perawatan dan mampu menangani tepung yang dihasilkan. Keberlanjutan program ini diharapkan mampu menghasilkan produk-produk turunan dari tepung ikan rucah sehingga dapat meningkatkan perekonomian masyarakat nelayan.

Abstract

Kelompok Tani Panca Karya di Desa Sinar Sari Kecamatan Kalirejo telah lama memanfaatkan pupuk organik untuk memupuk sawah dan ladang mereka, bahkan menurut penuturan salah satu anggota kelompok tani bahwa secara turun-temurun mereka memanfaatkan pupuk kandang (kotoran hewan) dan pupuk kompos (seresah dan sisa-sisa tanaman pertanian) untuk menyuburkan tanah pertanian. Kelompok Tani Panca Karya telah berkomitmen untuk memproduksi dan mengembangkan pupuk organik padatan menjadi Pupuk Organik Granul (POG). Permasalahan utama yang mereka dihadapi adalah cara membuat POG yaitu proses pembuatan butiran, selama ini butiran dibuat dengan menggunakan nampan dengan cara menginteri, dimana kapasitasnya sangat terbatas dan ukurannya tidak seragam. Sementara proses pembuatan butiran dapat menggunakan granulator, salah satunya adalah granulator yang telah dihasilkan oleh Jurusan Teknik Pertanian Universitas Lampung. Kapasitas mesin granulator ini sekitar 100 kg/jam, butiran yang dihasilkan berbentuk bulat dan seragam. Oleh karena itu pada pengabdian ini diaplikasikan mesin pembuat butiran (granulator) tersebut. Pelaksanaan pengabdian pada Kelompok Tani Panca Karya berjalan dengan baik. Mesin granulator POG dapat diaplikasikan pada kelompok tani (mitra) dengan baik dan pengetahuan mitra secara keseluruhan meningkat sekitar 65% yaitu dari 21,67% menjadi 86,67%. Kegiatan pengabdian serupa sangat diharapkan oleh mitra, mereka menginginkan adanya introduksi teknologi yang dihasilkan oleh Perguruan Tinggi, secara khusus mitra menginginkan introduksi peletting benih dan alsintan kedelai.

Abstract

Salah satu tujuan Laboratorium Lapang Terpadu adalah menjadi pusat pengenalan dini pertanian secara integal melalui program early agroeducation dan agroturism. Program ini menjadi salah satu pembelajaran pertanian bagi anak-anak sejak dini. Program pengabdian ini diikuti oleh anak-anak SD Insantama Bandar Lampung Kelas I. Anak-anak dikenalkan dan diajari cara mengolah tanah, menanam, menyiangi rumput, memupuk, dan memanen tanaman yang mereka tanam. Anak-anak juga diajak berkeliling Lab. Lapang Terpadu untuk mengenal tanaman-tanaman yang ada di Lab. Lapang Terpadu. Kegiatan ini berjalan dengan baik dan mampu memperkenalkan pertanian secara dini kepada anak-anak serta dapat menumbuhkan kecintaan anak terhadap bidang pertanian tanpa mengganggu pelayanan Lab. Lapang Terpadu terhadap pelaksanaan praktikum dan penelitian mahasiswa dan dosen. Anak-anak mengikuti program ini dengan senang dan interaktif, walaupun kegiatan yang dilakukan cukup melelahkan dan berkutat dengan lumpur. Hal ini menunjukkan bahwa fungsi kegiatan pengabdian ini sebagai aktivitas rekreatif bagi anak-anak juga didapatkan sehingga program early agroeducation dan agroturism dapat tercapai dengan baik.

Abstract

AbstractFlow behavior of Soy Protein Isolate (SPI) suspension and Whey Protein Isolate (WPI) solution at pH 2.0 under various heating times were studied using steady shear viscosity measurements. Shear rate sweeps with increasing shear rates (up ramp) was performed to investigate the structural breakdown of the proteins during shearing. Down ramp shear rates were performed to check structural recovery of the proteins. The results showed that unheated SPI suspension has Newtonian flow; meanwhile, unheated WPI solution was slightly shear thickening. Heating the proteins at 80ºC for 4, 8, 12, and 16 h changed flow behavior of the proteins. Flow curve of SPI suspension heated for 12 h and 16, fitted Ostwald model with flow behavior index (n) of 0.625 and 0.264, respectively. This index indicates pseudoplastic (shear thinning) behavior, which also observed in heated WPI solution. The changes in flow behavior was attributed by the changes in protein structures, i.e., globular structures into fibrillar structures under prolonged heating at acidic condition. This conversion also increased the apparent viscosities of the proteins. SPI fibrils have higher apparent viscosities than WPI fibrils. This difference might be attributed to the detail fibril structures. SPI fibrils have branched and curvy structures; meanwhile, WPI fibrils are long and straight.AbstrakPerilaku aliran suspensi Soy Protein Isolate (SPI) dan larutan Whey Protein Isolate (WPI) pada pH 2.0 pada berbagai lama pemanasan diinvestigasi. Shear rate yang meningkat diaplikasikan untuk mengetahui kerusakan struktur protein selama geseran. Shear rate dengan pola menurun dilakukan untuk mengetahui apakah strukturprotein kembali ke struktur awal setelah mengalami kerusakan. Hasil penelitian menunjukkan bahwa suspensi SPI yang tidak dipanaskan memiliki perilaku aliran Newtonian; sementara larutan WPI yang tidak dipanaskan bersifat sedikit shear thickening. Pemanasan protein pada 80ºC selama 4, 8, 12, dan 16 jam mengubah perilaku aliran suspensi SPI dan larutan WPI. Kurva aliran suspense SPI yang dipanaskan selama 12 jam dan 16 jam sesuai dengan model Ostwald dengan indeks perilaku aliran (n) masing-masing 0.625 dan 0.264. Indeks ini mengindikasikan perilaku aliran bersifat pseudoplastic (shear thinning), yang juga teramati pada larutan WPI yang dipanaskan. Perubahan perilaku aliran disebabkan oleh perubahan struktur protein dimana SPI dan WPI awalnya memiliki struktur globular lalu menjadi struktur fibrillar akibat pemanasan yang lama pada kondisi asam. Perubahan struktur juga meningkatkan nilai apparent viskositas, dimana viskositas fibril SPI lebih tinggi daripada fibril WPI. Perbedaan ini diakibatkan oleh perbedaan struktur fibril protein dimana SPI berbentuk fibril yang bercabang dan melengkung sedangkan WPI berbentuk fibril yang lurus dan panjang.

Abstract

Number of constraints in drying of mangosteen peel came as problem in handling of the product. The hybrid drying system was chosen as an alternative to dry the mangosteen peel. The treatments performed in this research were: the rack dryer hybrid where sunlight, electric, and combination of sunlight and electric source, and as a comparison were used the para-para dryer. Combination of sunlight and electric source has the highest temperature that was 48.5 C deg. using electric source was 38.1 C deg., whereas using sunlight source was 39.6 C deg. and using para-para dryer was 33.6 C deg. Drying with combination of sunlight and electric source was the most rapid in moisture evaporation. While as a comparison was used the para-para dryer, that was the slowest one. Drying efficiency using sunlight source was 29.6%, while the drying efficiency using electric source was 51.5%, and the combination of sunlight and electric source was 28.7%. It was concluded that the hybrid dryer could be used as an alternative to dry mangosteen peel.Keywords: mangosteen peel, drying energy source, drying efficiency
