Abstract

Indonesia is an agricultural country consisting of 17,504 islands, each of which has different biodiversity potentials. Increase in trade traffic today supported by the modernization of a fast-paced and sophisticated transpotation tool enables the spread of quarantine animal diseases from abroad into Indonesia, or across Indonesia.A conveyance means used to transport animals or livestock from one area to another. This conveyance means in direct contact with the animals brought. The conveyance has the potential to transmit the disease from one animal to another and from one area to another. Animal transport means can be sea ships, cars, box cars, trucks, baskets etc.Reducing the potential of disease transmission carried by conveyance, quarantine action is required on the means of conveyance. One of the measures against conveyance is disinfection. Disinfection is a process of reducing the number of disease-causing or potentially pathogenic microorganisms by physical and chemical. Disinfection is done using a variety of disinfectants that are easy to find and easy to use. The types of disinfectants commonly used in disinfection are iodine, alcohol, ammonium quartener, formaldehyde, potassium permanganate, phenol.With this test, it is expected to get the type and effective disinfectant concentration to kill pathogenic microorganisms so that animal diseases transmission from transportation can be minimized.To determine the type and concentration of effective disinfectants to kill pathogenic microorganisms especially spores that can be transmitted through a variety of conveyances.

Abstract

ABSTRAKLaboratorium lapang terpadu (Lab. LT.) merupakan salah satu laboratorium yang terdapat di Fakultas Pertanian Universitas Lampung.  Memiliki luas 67.000 m², yang terbagi menjadi 5 bagian utama yaitu lahan usaha, lahan penelitian dan praktikum, lahan ternak, kolam ikan, dan lahan tidak terpakai.  Penelitian ini menggunakan model linear programming berdasarkan metode simpleks dengan bantuan software QM For Windows.  Tujuan dari penelitian ini yaitu merumuskan formulasi matematika model linear programming dan menghitung nilai keuntungan optimal bagi pengelolaan Lab. LT.  Hasil penelitian menunjukan bahwa nilai keuntungan data asumsi lebih besar dari data asli berdasarkan kondisi Lab. LT.  Keuntungan yang diperoleh setiap tiga bulannya jika nilai Zmax (x2) sama dengan nol yaitu Rp.22.200.370, dengan ketentuan luas lahan usaha ditambah 0,52% dari luas sebelumnya dan untuk kolam ikan ditambah 2,22% dari luas sebelumnya.  Sedangkan berdasarkan nilai asumsi keuntungan yang akan diperoleh setiap tiga bulannya yaitu Rp.34.810.000, dengan ketentuan luas lahan penelitian dan praktikum ditambah 1% dari luas lahan sebelumnya dan untuk kolam ikan ditambah 2,33% dari luas kolam yang digunakan sebelumnya.  Selisih keuntungan yang diperoleh dari data asli dan data asumsi yaitu sebesar Rp. 14.821.850 setiap 3 bulannya.__________________________________________________________________Kata kunci: Optimalisasi, riset operasional, linear programming, metode simpleks, QM for windows.

Abstract

Caulerpa racemosa atau dikenal dengan nama latoh adalah salah satu komoditas perikanan yang digemari karena memiliki kandungan gizi yang tinggi. Namun, dalam budidaya C. racemosa masih terdapat kendala yaitu produksi yang belum maksimal dan pertumbuhan yang belum optimal. Salah satu cara untuk meningkatkan pertumbuhannya yaitu dengan melakukan perendaman bibit rumput laut menggunakan hormon pertumbuhan dari ekstrak bahan alami. Jagung merupakan salah satu bahan alami yang mengandung hormon pertumbuhan giberelin, sitokinin, dan auksin. Hormon tersebut dapat merangsang pertumbuhan batang dan akar. Tujuan dari penelitian ini adalah untuk mengetahui efektivitas penambahan hormon dengan menggunakan ekstrak kasar jagung terhadap pertumbuhan dan morfologi C. racemosa dan mengetahui lama waktu perendaman terbaik ekstrak kasar jagung terhadap pertumbuhan C. racemosa. Penelitian ini dilakukan dengan menggunakan metode eksperimen dengan Rancangan Acak Lengkap (RAL) yang terdiri dari 4 perlakuan dan 3 kali pengulangan. Perlakuan yang dilakukan yaitu perendaman selama 0 menit (sebagai kontrol) (A), 30 menit (B), 40 menit (C), dan 50 menit (D). Data yang diperoleh selama penelitian meliputi morfologi, pertumbuhan bobot mutlak, laju pertumbuhan spesifik, dan kualitas air. Lama waktu perendaman C. racemosa dalam media ekstrak kasar jagung berpengaruh nyata (P<0,05) terhadap pertumbuhan. Perlakuan B menunjukkan hasil terbaik terhadap pertumbuhan bobot mutlak (123,63 ± 6,55 g) dan laju pertumbuhan spesifik (4,15 ± 0,21% per hari). Perlakuan B memiliki morfologi thalus dan ramulli yang besar serta rimbun. Parameter kualitas air dalam kisaran yang sesuai untuk pertumbuhan C. racemosa.Caulerpa racemosa, known as latoh, is a popular edible green alga due to its high nutritional content and medicinal benefits. However, low quality and slow growth of seed prevented the aquaculture development C. racemosa. Soaking the seaweed seed with growth hormone immersion from extracts of natural ingredients could potentially improve its growth rate. Corn contains growth hormone gibberellins, cytokinins, and auxins. These hormones can stimulate the growth of stems and roots. This study aimed to determine the effectiveness of growth hormones in corn crude extract and the best soaking time of the extract on the growth development and morphology of C. racemosa. This research was conducted using an experimental method with a Completely Randomized Design (CRD) consisting of four treatments with three replicates. The treatments were soaking the seed in corn extract for 0 minutes (as a control) (A), 30 minutes (B), 40 minutes (C), and 50 minutes (D). The data obtained during the study included morphology, absolute weight growth, specific growth rate, and water quality. The duration of immersion of C. racemosa in maize extract media had a significant effect (P<0.05) on growth. Treatment B showed the best results with absolute weight growth and growth rate values of 123.63 ± 6.55 g and 4.15 ± 0.21% per day, respectively. This research successfully determines that corn extract improves the growth of C. racemosa seeds indicated by the large thallus and ramuli of the cultured seaweed.

Abstract

Biogas technology from floating drum-type cow dung made in Rejomulyo village, Jati Agung sub-district, South Lampung, can produce biogas for daily fuel. However, the residual waste or biogas dregs (sludge/bio-slurry) have not been utilized, only disposed of at a waste disposal site. This community service activity aims to increase the added value of biogas waste by utilizing sludge/bio-slurry for organic fertilizer in vegetable cultivation in yards and gardens. The activity was carried out using the extension method for making vegetable cultivation pilot units using sludge/bio-slurry. Furthermore, through Gapoktan and Agricultural Extension as companions, it can be developed in people's homes that have a biogas digester. The conclusion is that cow dung as waste from livestock business has been successfully converted into biogas and slurry. The success of this training is indicated by the high enthusiasm of the participants and the ongoing implementation of liquid fertilizer (bio-slurry).
