Abstract

This study aims to: (1) determine the potential and condition of the mangrove forest ecosystem in Muara Bandeng Village, Una-una District, Tojo Una-Una Regency. (2) determine the level of damage to mangroves in Muara Bandeng Village, Una-una District, Tojo Una-Una Regency. (3) formulate recommendations for alternative strategies for the further development and management of mangrove forests in Muara Bandeng Village, Una-una District, Tojo Una-Una Regency. The sampling method is the checkered line method. This research is a quantitative descriptive research . The results of the study show the following: (1) The potential of mangrove forests in Muara Bandeng Village, Una – Una Sub-district, Tojo Una – Una Regency can still be developed to help the community's economy with support and direction from the local government and other environmentalist organizations. The condition of the mangrove ecosystem in Muara Bandeng Village is in a damaged condition. (2) Based on the analysis, it shows that the level of damage to the mangrove forest in Muara Bandeng Village is in the damaged category. This is supported by the results of the analysis of the level of damage to mangroves. Based on the analysis of the level of ecosystem degradation, the TNS value is 225. (3) strategic recommendations Strategies that can be carried out are as follows : (a) Organizing skills training in managing mangroves (ecotourism and nursery) to increase people’s income, (b) Increase information shared through new technology to attract foreign tourists.

Abstract

Phytobiotics are derivated from the plants which contains active compounds. They produce antibacterial and antioxidants activity and can improve the condition of the digestive tract. Papaya leaf extracts and mint leaf extracts have the potential as natural phytobiotics because they have antibacterial, antioxidant properties, can improve alimentary tract conditions and increase the absorption of nutrients in the feed. The aim of this study was to compare the utilization of papaya leaf extract (EDP) and mint leaf extract (EDM) in feed on the production and quality of quail egg. A hundried and fourty quails of 42 days age were arranged in a completely randomized design with 5 treatments and 4 replicates (7 quails per replicate). The treatment diets consisted of P0 = Basal diet only (Control), P1 = Basal diet + 100 ppm EDP, P2 = Basal diet + 200 ppm EDP, P3 = Basal diet + 100 ppm EDM and P4 = Basal diet + 200 ppm EDM. The results approved that mint leaf extract reduces in feed consumption, increase egg production and mass and reduce feed conversion values, in contrast the papaya leaf extract ​​produce non-significant on those variables. However, papaya leaf extract was able to increase more white index values and haugh unit ​​of quail egg, while mint leaf extract increased more yolk index values. The addition of 100 ppm mint leaf extract resulted in the highest value of egg production and egg mass. Therefore, the perfomance and quality of eggs in mint leaf group were better than papaya leaf group.

Abstract

The research aims to find out how much influence legume leaf compost and microbes on improving nutrient absorption andgrowth of ebony seedlings. The research was conducted from August 2, 2022 to February 2, 2023 for 6 months at the BPDAS Palu-Poso Permanent Nursery. The compost used is compost derived from legume leaves consisting of gamal, lamtoro, and turi trees and the microbes used are Plant Growth Promoting Rhizobacteria (PGPR) and Plantarum Plant Growth Stimulant (PPGS) which are microbes that are widely traded in agricultural specialty online stores, The samples of this study amounted to 108 ebony seedlings with 12 treatments andeach treatment contained 9 seedlings/samples. This study used analysis of variance of complete randomized design (CRD) to determine the significant and non-significant effects of each treatment by looking at several variables from height, diameter, number of leaves, sturdiness, nutrient uptake, seedling quality index in each seedling/sample. The results showed that seedlings treated with tailings soil + lamtoro leaf compost + PGPR microbes (K3M2) had the best average growth in each variable. While the lowest growth of seedlings with control soil treatment (K0M0).

Abstract

Central Sulawesi's 2018 earthquake, liquefaction, and tsunami caused liquefaction in Palu City's Balaroa and Petobo neighbourhoods. Land surface changes affected agricultural land area and soil fertility, which can affect farmers' income. Soil fertility indicates its nutrient-providing capacity. This study aims to assess agricultural land fertility, farmer income, and the best ways to recover from natural disasters. This descriptive study included all Petobo farmers affected by the earthquake and liquefaction. Purposive sampling tested 25 respondents. The field survey collected soil samples at coordinate points. Twelve soil samples were taken from six points at 20 cm and 40 cm depths. The samples were analysed at Tadulako University's Environmental and Natural Resources Analysis Laboratory. The results showed that Petobo Village's liquefaction-affected and unaffected areas had low fertility due to low C-organic and Potassium content, which prevented plants from using soil nutrients. Low soil fertility reduces crop production. Farmers earn an average of Rp. 1,422,857 per hectare, up to Rp. 4,633,929 per season per hectare. To increase soil fertility, farmers can use compost, manure, crop residues like legume plant stover, rice straw, and chemical fertilisers according to dosage.

Abstract

Giving vitamin C to feed is very necessary considering that vitamin C is a multivitamin needed by the body. The purpose of this study was to determine the proper dose of vitamin C in the golden snail silage feed in increasing the biomass and reproduction of Artemia sp. The research was conducted at the Laboratory of Water Quality and Aquatic Biology, Department of Fisheries and Maritime Affairs, Faculty of Animal Husbandry and Fisheries, Tadulako University. The variables observed were population density, egg/cyst production, hatching rate, survival rate (SR), water quality. The study used a completely randomized design (CRD) with 5 treatments and 4 replications with 20 experimental units A: control , B: vitamin C 12 mg/L, C: vitamin C 18 mg/L, D: vitamin C 24 mg/L, E: vitamin C 30 mg/L. The results showed that vitamin C enrichment with a concentration of 24 mg/L had a very significant effect (p<0.05) on each variable. Improper concentration of vitamin C in feed enrichment can affect the survival of Artemia sp.
