Abstract

Polikultur merupakan kegiatan budidaya perikanan dalam satu wadah yang menghasilkan lebih dari satu jenis organisme secara bersamaan. Penelitian ini bertujuan untuk mengetahui pengaruh sistem polikultur terhadap pertumbuhan ikan nilem. Penelitian ini menggunakan metode eksperimen Rancangan Acak Lengkap (RAL) dengan 6 perlakuan dan 3 kali ulangan yaitu P0 (15 nilem), P1 (5 lobster air tawar dan 15 nilem), P2 (10 lobster air tawar dan 15 nilem), dan P3 (15 lobster air tawar dan 15 nilem), P4 (20 lobster air tawar dan 15 nilem), P5 (25 lobster air tawar dan 15 nilem). Hasil penelitian menunjukkan bahwa perlakuan padat tebar lobster yang berbeda mempengaruhi pertumbuhan ikan nilem. Hasil pengukuran tertinggi pertumbuhan bobot mutlak, yaitu 7,21 g, panjang mutlak 4,59 cm, laju pertumbuhan spesifik 2,93%, kelulushidupan 93,33%, dan konversi pakan 1,26%, hal ini disebabkan karena kepadatan tebar lobster air tawar pada P2 rendah. Kepadatan penebaran yang rendah memberikan ruang bagi ikan nilem untuk bergerak dan hidup. Pemeliharaan sistem polikultur lebih baik dilakukan pada 10 ekor lobster air tawar dan 15 ekor ikan nilem karena menghasilkan pertumbuhan panjang dan bobot mutlak terbaik.

Abstract

The responsibilities of the Land Deed Official (PPAT) include administrative and legal responsibilities. Procedures that are not in accordance with the regulations for making authentic deeds of land sale and purchase agreements will have an impact on the strength of the deed of agreement and even on the Land Deed Making Official himself in accordance with Government Regulation Number 24 of 2016 concerning the Position of Land Deed Making Officials and regulations regarding the Code of Ethics for the Association of Deed Making Officials. Land. The implication of errors in the procedure for making the deed is that the PPAT was dishonorably dismissed from his position, and weakened the strength of the authentic deed of sale and purchase to become a private agreement. Factors that influence PPAT in violating the regulations for making authentic deeds, there are actions that PPAT must take in order to save the sale and purchase transaction, There is mutual trust between the parties including PPAT officials, Time factors and strong relationships cause PPAT to make authentic deeds that are not in accordance with procedures and procedures for making deeds in accordance with applicable regulations.

Abstract

The Arduino Uno is a device commonly used as the brain of a control system. It utilizes an Integrated Circuit (IC) known as the ATMega328P. The Arduino Uno comes equipped with a user-friendly programming environment, making it suitable for both beginners and experienced developers. It finds applications in various devices, such as the Coconut Grater and Coconut Squeezer machines. In the case of these machines, the Arduino Uno is employed to control the direction of the Coconut Squeezer's motor rotation and the activation of the Coconut Grater's motor using buttons. The objective of this journal is to identify the components used for controlling input/output and to understand the programming techniques for the Arduino Uno. The findings from this journal provide insight into the components utilized in the Coconut Grater and Coconut Squeezer machines and serve as a blueprint for their construction. This design aims to ensure the precise control of the Coconut Grater and Coconut Squeezer machines.
