Abstract
Mahogany (Swietenia macrophylla King.) is a tree species that has considerable potential for the development of plantation forests. However, mahogany plant propagation is generally done generatively, namely by seed. Mahogany seeds are intermediates that have a low shelf life and take 9-12 months from flowering to ripe fruit. The efforts that can be made are through vegetative means, with tissue culture. The success of tissue culture is strongly influenced by the growth medium, which is one of the main factors in plant propagation and has a major influence on the growth and development of explants and seeds produced. The purpose of this study was to obtain the best-growing media for optimizing the growth of mahogany explants in vitro. The research method used was a Completely Randomized Design (RAL) with 1 factor, namely the type of medium with three replications. Variables, namely the time of leaf emergence, the timing of the shoot^s emergence, the number of shoots, and plant height. The results showed that MS media with the addition of adenine sulfate, 0.5 ppm BAP, and 0.2 ppm Kinetin were the best medium for the growth of mahogany (explants.

Abstract
White teak (Glemina Arborea Roxb) is a type of wood that comes from community forests. Physical and mechanical properties are one of the basic properties of wood. Knowledge of these two properties is needed to determine the utilization of these types of wood. The purpose of this study was to determine the physical and mechanical properties of white teak wood from Lolu Village. The research was conducted from November to December at the agronomy and soil science laboratory and the concrete and building materials laboratory at Tadulako University. The results of the research on the physical properties of white teak wood showed that on average, air dry moisture content, density and shrinkage were 147.36%- 20.03%- 0.49 gr/cm3. The results of the study of the mechanical properties of eucalyptus showed that the average values of MOE, MOR, and compressive strength parallel to the fibers were 18448.58 kg/cm2, 632.48 kg/cm2, respectively- 233.33 kg/cm2.

Abstract
Aflatoxins are secondary metabolites produced by Aspergillus fungi. Feed exposure to aflatoxins may cause a decreased immune system and low productivity outcomes in poultry. This study conducted a limited survey to determine aflatoxin contaminations in feedstuff. 34 feed samples were analyzed to determine aflatoxin B1, aflatoxin B2, aflatoxin G1, and aflatoxin G2 using High-Performance Liquid Chromatography (HPLC) fluorescent detector. Aflatoxins were extracted from feed samples using acetonitrile : water (84:16,v/v), purified with a solid phase extraction (SPE) column, and detected through a fluorescent detector at wavelengths 365 nm (excitation) and 450 nm (emission). The results show a high concentration of AFB1 contamination in 34 samples. AFB1 were detected in 28 samples ranging from 1.38 to 1467,37 ng/g. AFB2 were detected in 27 samples ranging from 0.12 to 6.86 ng/g for AFB2. On the other hand, AFG1 and AFG2 were not detected in all samples. The high prevalence and concentration of AFB1 in most samples were harmful to the animals and should be a concern to prevent any adverse effect on public health

Abstract
The Banggai cardinalfish (Pterapogon kauderni Koumans, 1933) is an ornamental fish with an endemic distribution in the Banggai Archipelago and nearby small islands. One of the 20 Indonesian Ministry of Marine Affairs and Fisheries conservation priority species, sustainable management initiatives include reducing fishing pressure on wild P. kauderni populations and optimising both in situ and ex-situ breeding. This study continued previous ex-situ research on artificial microhabitat for rearing P. kauderni in captivity by comparing the relative effectiveness of urchin-like artificial microhabitat with ^spines^ made from different materials in terms of P. kauderni growth and survival. Experimental fish collected from the Palu Bay introduced population comprised 48 P. kauderni juveniles with initial standard length 2-2.5 cm and weight 0.06-022 g. The fish were reared for one month in the Aquatic Biology Laboratory, Fisheries and Marine Department, Faculty of Animal Husbandry and Fisheries, Universitas Tadulako, Palu. The experimental design included four treatments (microhabitat material: A. cable ties- B. bamboo slivers- C. palm leaf rachis- D. palm fibre/coir) with four replicates and three fish per experimental unit (aquarium). The ^spine^ material had a significant effect on net weight gain but not on net increase in length. Weight gain and survival rate were highest under treatment D (cable tie ^spines^).

Abstract
High total plate count (TPC) and the presence of Salmonella in food products can cause health problems for consumers. Bone-free milkfish products are popular with consumers in Palu City, Central Sulawesi, Indonesia, but there is a lack of data on their safety. Therefore this study aimed to investigate TPC levels and the prevalence of Salmonella in these products. Samples of fresh and processed milkfish were collected from two bone-free milkfish processing sites, namely the Technical Implementation Unit for Application of Quality of Fishery Products (TIU-AQFP) and the Melona Micro, Small and Medium Enterprise (MSME) Group in Palu City. Microbiological assays included counting the number of bacterial colonies (TPC) and the isolation and identification of Salmonella through biochemical tests. The study applied a completely randomized factorial design with three replicates per site and per product (12 experimental units). No Salmonella contamination was found in the test samples. Bone-free processing had a significant effect on TPC- however, the types of bacteria identified in fresh and bone-free milkfish, including Klebsiella, Enterobacter and Citrobacter, were present at non-pathogenic levels. These results indicate that bone-free milkfish products from the TIU-AQFP and Melona MSME Group in Palu City are safe and suitable for human consumption.

Abstract
The Covid-19 pandemic that has occurred in Indonesia has brought many significant impacts on human life in various aspects of people^s lives. Policies during the pandemic such as Work From Home (WFH) and Large-Scale Social Restrictions (PSBB) have also had a socioeconomic impact on the community, including the most basic needs, namely food. On the other hand, agricultural land that continues to be eroded for the benefit of development and the age of farmers who are on average old whose ability to grow them is declining also play a role in the decline in food. The threat of a food crisis is now gradually beginning to haunt the entire society. Based on Global Hunger Indonesia (GHI) data, the hunger rate of people in Indonesia is in the serious category even though it has decreased from 24.9% (2010) to 20.1% in 2019. Indonesia must remain vigilant against the threat of famine that can trigger various kinds of major issues such as health, social and security. Urban farming is a gardening concept by utilizing the space in the house or settlement. Based on the foregoing, urban farming is very supportive and gives positive appreciation because it has proven to provide more benefits for the community in the midst of a pandemic. A number of studies also mention that urban farming can be an ideal agricultural concept in the future. In addition to the considerable benefits of urban farming, the main challenges in urban farming are determining how to monitor, regulate, and minimize risks in environmental, economic, and socio-environmental forms and understanding how urban farming can be sustainable in urban food systems globally. Urban agriculture can increase the value of food locality and reduce the energy spent in the fruit and vegetable production process. Therefore, the city government has an important role in providing specific regulations to support the implementation of sustainable urban farming.
