No full textTraces of the long history of agricultural credit history in Indonesia are divided into (i) Pre-Bimas (1964); (ii) National Community Guidance and Gotong Royong (1965-1970); (iii) Improved Guidance (1970-1984); (iv) Agricultural Business Credit (1985-1999); (v) Food Security Credit (2000), Food and Energy Security Credit (2007) and People's Business Credit (2007 to present). However, until now there has not been a single consistent credit scheme that specifically deals with rice commodities. Thus, the capacity building of rice farmers in adopting advanced technologies such as quality seeds, balanced fertilizers, water pumping machines, tractors, power threshers, combine crushers, and processing of products based on the industrial revolution 4.0 in order to increase the added value of rice food agricultural products cannot be realized. Research objectives include; 1. Assess the constraints/obstacles in the distribution of rice commodity agribusiness business financing schemes from the perspective of financial institutions and rice commodity agribusiness farmers and 2. Design innovative banking-specific financing solutions models for rice commodity agribusiness businesses. This research was conducted from August to December 2022, in Gowa Regency, South Sulawesi Province. The results of this collaborative research can be stated: (1) Obstacles/obstacles in terms of bank lending are relatively centralized lending policies and from the agribusiness farmer's side are weak financial administration systems and lack of bankable guarantees; and (2) The model for innovative banking-specific financing solutions for rice commodity agribusiness produced in the research is the Rice Agribusiness Credit Skim (KAP), in which the role of the Regional Government is as Advisor and Coordinator.Jejak rekam perjalanan panjang sejarah kredit pertanian di Indonesia dibedakan menjadi : (i) Pra-Bimas (1964); (ii) Bimas Nasional dan Gotong Royong (1965-1970); (iii) Bimas Disempurnakan (1970-1984); (iv) Kredit Usaha Tani (1985-1999); (v) Kredit Ketahanan Pangan (2000), Kredit Ketahanan Pangan dan Energi (2007) dan Kredit Usaha Rakyat (2007 sampai sekarang). Namun sampai saat ini tidak ada satupun skim kredit yang konsisten khusus menangani komoditi padi. (Zulkifli, Sri Mardiyati, Hamzah, Abubakar Idhan, Suhartina, (2021)
Dengan demikian, capacity bulding petani padi dalam mengadopsi teknologi maju seperti benih bermutu, pupuk berimbang, alsintan pompa air, traktor, power thresher, combined havester dan pengolahan hasil berbasis revolusi industri 4.0 dalam rangka meningkatkan nilai tambah produk pertanian pangan padi tidak dapat diwujudkan.

No full textKoi carp (Cyprinus carpio) is one of the attractive ornamental fish to be cultivated because it has a gorgeous color and high economic value, so koi carp is in great demand by the public. The beautiful color of koi carp is influenced by the presence of natural pigments in fish; to release that color, it is necessary to add color pigments from synthetic substances. One of the natural ingredients that contain color pigments is purple sweet potato. This study aims to determine the effect and the correct dose of adding sweet potato flour to the intensity of the color brightness of koi carp (Cyprinus carpio). This research was carried out in stages, starting with the supply of raw materials for feed and carp koi (Cyprinus carpio). Then, the use of fish color measuring instrument parameters, namely toca color, measurement of absolute growth, survival rate, feed conversion, and feed efficiency. In the next stage, the research focused on fish maintenance and using optimal feed doses against changes for 90 days. The study's results showed that the highest change in color brightness was in treatment C (of purple sweet potato flour 15%) with a value of 6. Then, treatment A (5%), as much as 5.56, followed by treatment D (control), did not experience an increase in brightness color. Treatment B (10%) has the lowest color brightness level of 4.89. The results of these numbers are adjusted to the analysis test results (p> 0.05), which shows that the feeding of purple sweet potato flour has no significant effect on changes in the color's brightness level, and the results of the efficiency of feed utilization
