    Kajian ini dijalankan bertujuan mengenalpasti dan memahami sejauh manakah kepenggunaan sesebuah ruangan awam serta mengkaji karakter fizikal dan aktiviti-aktiviti yang dilaksanakan oleh masyarakat sekeliling yang mempengaruhi aktiviti tersebut. Ruangan awam yang telah dipilih ialah ruangan Lebuh Medan Pasar yang terletak di tengah kawasan Kuala Lumpur Lama. Ruang awam tersebut dipilih kerana menjadi tumpuan masyarakat di ibu kota serta mempunyai kepentingan dan keistimewaan sejarah yang tersendiri. Kajian ini mengaplikasikan kaedah metodologi kualitatif dimana ia melibatkan dua teknik pengumpulan data iaitu kajian kes, pemerhatian di tapak kajian serta kajian literatur. Teknik pemerhatian akan dianalisa secara kualitatif di mana pendekatan pemerhatian berstruktur digunakan. Oleh itu, hasil penemuan dan dapatan kajian ini akan membantu dalam membangunkan kawasan kajian serta mengekalkan elemen penting sebagai identiti setempat terhadap ruangan awam tersebut

    Program pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kapasitas pengetahuan sistem bertani hidroponik bagi kelompok Karang Taruna Lingkungan Karang Anyar Kota Mataram. Penerapan sistem bertani hidroponik sangat cocok digunakan di daerah perkotaan karena memiliki beragam keunggulan, diantaranya adalah pertumbuhan tanaman dapat dikontrol, kuantitas dan kualitas hasil produksi tanaman tinggi dan yang paling utama adalah dapat diaplikasikan secara optimal pada lahan yang terbatas. Adapun metode pelaksanaan kegiatan pengabdian kepada masyarakat ini dilakukan dengan melalui tiga tahapan, antara lain: (1) Tahapan Persiapan; survey pendahuluan yang merupakan tahapan untuk melihat kondisi awal mitra akan kebutuhan serta potensi yang ada, (2) Tahapan Pelaksanaan; sosialisasi dan pelatihan bertani dengan sistem hidroponik, dan (3) Tahap Akhir; pendampingan dan evaluasi kegiatan untuk menilai sejauh mana mereka memperoleh manfaat dari bertani dengan sistem hidroponik. Meningkatnya kapasitas pengetahuan mitra tentang sistem bertani hidroponik, keterampilan untuk mengaplikasikan serta wawasan saluran distribusi penjualan diharapkan dapat menjadi alternatif bagi mereka untuk memperoleh manfaat secara ekonomi dan sumber tambahan penghasilan

    The present work aimed to establish the prevalence of mycobiota and occurrence of mycotoxins (aflatoxins and ochratoxin A) in spices and spice-based products, and correlate these to their manufacturers’ sizes. A total of 90 spice, sauce and paste samples were purchased; 3 manufacturer sizes (small, medium, large) × 3 types of samples (spices, sauces, pastes) × 5 brands × 2 replicates. The prevalence of mycobiota was assessed with dichloran rose bengal chloramphenicol (DRBC) and Aspergillus flavus and Aspergillus parasiticus (AFPA) medium, while the occurrence of mycotoxins was quantified with HPLC-FLD. Large-scale manufacturers were found to adopt a greater number of safety and quality certifications. Small-scale manufacturers significantly yielded the highest total fungal loads on DRBC (log 5.084±0.417 cfu/g paste, log 6.253±0.407 cfu/g sauce, log 6.662±0.222 cfu/g spice) and AFPA (log 4.461±0.451 cfu/g paste, log 5.661±0.395 cfu/g sauce, and log 6.269±0.432 cfu/g spice). Correlation analysis (Pearson’s r) revealed that manufacturers’ sizes positively influenced (DRBC r=0.781; AFPA r=0.702) the prevalence of mycobiota. Aflatoxin B1 was present in 6/30 (20%) paste samples, 1/30 sauce samples (3.33%) and 12/30 spice samples (40%). Aflatoxin B2 was only present in 2/30 sauce samples (6.67%). Aflatoxin G1 and G2 were absent from all samples. Ochratoxin A was present in 11/30 (36.67%) paste samples, 5/30 sauce samples (16.67%) and 21/30 spice samples (70%). It was found that, to a certain extent, the size of and certification adopted by manufacturers affected the prevalence of mycobiota and the occurrence of mycotoxins in spices and spice-based products analysed in the present work. Nevertheless, it is henceforth recommended that a surveillance study of this nature be extended and widened in terms of number of samples as well as type of spices, sauces and pastes to obtain a more thorough and significant profile of the products’ food safety and quality level

    Pemberian Pakan Yang Difermentasikan Dengan Probiotik Untuk Pemeliharaan Ikan Lele Dumbo (Clarias Gariepinus) Pada Teknologi Bioflok Feed Fermented Using Probiotic for African Catfish in Biofloc Technology

    This study aimed to determine the effect of feeding fermented with probiotic on, absolute body weight, absolute body length, specific growth rate, survival, feed efficiency and feed conversion rate of African catfish preserved biofloc techniques. The treatment in this study was the dose used for the fermentation of feed are 2 ml / kg (P1), 4 ml / kg (P2), 6 ml / kg (P3), and control (feed without fermented). Each treatment was repeated 3 times. 4-5 cm catfish were kept in the plastic tank with stocking density of 500 fish/m3 for 56 days. The fish are fed three times a day at satiation. The results showed fermented feed with probiotic on biofloc system affect absolute body weight, absolute length, specific growth rate, feed efficiency, and feed conversion rate of african catfish significantly, but did not affect survival rate. The best treatment was obtained from P3 which gives absolute body weight of 110.09 grams, absolute body length of 15.51 cm, specific growth rate of 8.03%, 92.62% survival rate, feed efficiency 117.22%, as well as feed conversion of 0.85

    This research was conducted from December 2015 until January 2016 at Technology Research and Development Center in Riau Balitbang. The purpose of this research was to investigate growth and survival rate of african catfish with difference of stocking density in bioflocs techniques. This research using experimental method and completely random design (RAL) with three treatment and three replications, three are P1 : Stocking density 200 ekor/m3, P2 : Stocking density 300 ekor/m3, P3 : Stocking density 400 ekor/m3. The result showed that african catfish with difference of stocking density in bioflocs techniques significant effect on quality of water, absolute length growth, spesific growth rate, the growth of absolute weight, and survival rate. The best treatment were obtained in treatment stocking density 300 ekor/m3, with value growth of quality of water (temperature 27-32oC, DO 3,09-4,16 mg/L, pH 6,7-7,1 and NH3 0,07-0,09 mg/L) absolute weight 50,15 g, growth in absolute length 12,63 cm, specific growth rate 3,99% and survival rate 98,16%

    Silk worms is one kind of natural food like fish larvae because they contain good nutrients for the growth of fish larvae. This study aims to determine the appropriate amount of fertilizer and the implementation of systems of recirculation to the growth of silk worms. The research was conducted on July 29 to September 18, 2016 placed in a field laboratory of the Faculty of Fisheries and Marine University of Riau. The media used is in the form of sludge reservoirs, dedek smooth, tofu, chicken manure and EM4. While the materials used are silk worms obtained from collectors. Experimental method used was a completely randomized design (CRD) with 3 levels of the factor treatments and 3 repetitions. The treatments used: P0: without the use of chicken manure, P1: 500 g of chicken manure / 0.098 m2, P2: 600 g of chicken manure / 0.098 m2, and P3: 700 g of chicken manure / 0.098 m2. The data observed is the growth of biomass weight, average length, and water quality. The results of this study with the treatment of chicken manure fertilizer of different very significant effect (P 0.05). The average length of the highest in treatment P2 (1.83 cm). Water quality measured during the study was the temperature (25-29˚C), pH (6-7), dissolved oxygen (6,0-6,5 ppm), and CO2-free (2,0-3,5 ppm). From this study it can be concluded that giving different chicken manure can affect the growth of silk worm
