Abstract

The purpose of this study was to determine the effect of the frequency of artificial feeding Hi-Pro-Vite 781N-1 on the effective growth of goldfish (Cyprinus carpio) in Timor Leste, Timor. The study used a complete randomized design (CRD) with 3 treatments and 3 replications, in which the conditions of the test unit are carried out according to randomization for all test units. The results of the research conducted for eight weeks (56 days) regarding the frequency for artificial feeding hi-pro-vite 780N-1 were: water temperature, water oxygen, sin water, and total dissolved solids (TDS) of 42.4 ppm, and the results of water quality measurements once a week in the morning (08.00 WIB), on average (20.00 htl) and in the afternoon (05.00) for 8 weeks (58 days). The results obtained during the research week (65 days) fresh at water temperature with a value of 20.2 oC with water oxygen 2.89 pmm, water content 8.3 pmm and TDS 42.4 pmm are indeed a good tolerance for the growth of carp fry (Cyprinus caprio). The behavioral impact of feeding frequency on carp growth and health is explored to refine feeding practices that promote well-being alongside growth. The findings could benefit feed manufacturers and aquaculture stakeholders by informing product development and feeding strategies tailored to maximize growth in carp, contributing to sustainable aquaculture practices. This study offers practical guidance for optimizing feeding practices to enhance growth efficiency, which is crucial for improving fish yield and farm productivity.

Abstract

This study investigates the coordination of coffee quality within the agro-commercial chain in Timor-Leste by analyzing the interaction between producers and companies engaged in production and commercialization. Coffee, as the country’s most important agricultural export and a key contributor to the non-oil economy, is internationally recognized as an organic product, with the Timor Hybrid (HDT) gaining global attention. Data were collected through documentary analysis and questionnaire surveys from 111 smallholder producers and 6 companies in Ermera Municipality, particularly in Leteffoho Administrative Post, the region with the largest plantation area and highest dependence on coffee as a source of income. The findings reveal that producers mainly cultivate Arabica and Robusta, with quality control focusing on cherry harvesting and processing, while companies predominantly purchase parchment coffee and determine prices based on quality, with only one company buying cherry coffee. All companies export green coffee, and four also sell roasted coffee in the domestic market. This study further proposes a framework that emphasizes coordination mechanisms between producers and companies to enhance quality assurance, sustain competitiveness in international markets, and strengthen the resilience of Timor-Leste’s agricultural economy.
