Abstract

Goldfish (Cyprinus carpio) is a type of food fish which is a freshwater fishery commodity that has good prospects. Goldfish (Cyprinus carpio) are animals that live in temperate climates and live in freshwater ponds. The aim of this research is to determine the effect of providing these 3 feeds and to determine the development and growth of goldfish after being treated with these three feeds. The method used in this research is an experimental method by providing treatment with the three feeds. Based on the research results, it was found that the growth and development of goldfish can be influenced by several things, including: age, size, density and space for movement. Each type of fish food has a certain daily growth rate value which depends on water quality.

Abstract

Kemacetan merupakan salah satu masalah utama yang dihadapi kota besar seperti Makassar, khususnya di Jalan Sultan Alauddin yang berfungsi sebagai jalan arteri primer. Aktivitas ekonomi yang tinggi, pertumbuhan penduduk, serta kurangnya infrastruktur yang memadai menyebabkan tingginya volume kendaraan setiap hari. Penelitian ini menggunakan pendekatan kualitatif untuk mengkaji tingkat kemacetan di Jalan Sultan Alauddin dan dampaknya terhadap produktivitas kerja masyarakat. Data dikumpulkan melalui observasi dan wawancara dengan pengguna jalan. Hasil penelitian menunjukkan bahwa kemacetan terjadi hampir setiap hari, terutam pada jam masuk dan pulang kerja. Kondisi ini berdampak pada waktu tempuh yang panjang, kelelahan fisik dan mental, serta penurunan konsentrasi dalam bekerja. Masyarakat telah menerapkan berbagai strategi seperti berangkat lebih pagi dan menggunakan jalur alternatif, namun solusi ini belum sepenuhnya efektif. Penelitian ini menekankan pentingnya penanganan yang lebih serius dari pemerintah, seperti penertiban parkir liar, penambahan jalur alternatif, edukasi lalu lintas, serta pemanfaatan teknologi untuk memantau kondisi jalan.

Abstract

The sensitive plant (mimosa pudica) is one of the unique plants because its leaves can fold when touched or stimulated. This plant has characteristics such as a small stem, sensitive leaves, and thorns around its stem. This plant is the subject of this laboratory work to understand the plant’s sensitivity to environmental stimuli.

Abstract

Kluwak shell carbon (KTK) is an eco-friendly adsorbent made from kluwak fruit biomass. The objective of this study is to investigate the impact of physical activation on KOH-activated kluwak shell carbon (KTKOH) within the temperature range of 500 - 900 oC, and to compare it with H3PO4-activated KTK (KTKH3PO4) and KTK. The performance of the adsorbent was evaluated by determining the maximum adsorption capacity (qm) of Methylene Blue (MB) using the Langmuir equation and the surface area of the Brunnaeur Emmet and Teller (BET) method. The Methylene Blue batch system was subjected to isotherm adsorption for 90 minutes, with a stirring speed of 220 rpm, 0.25 grams of adsorbent, and 50 ml at 6 concentrations of MB ranging from 60 to 200 ppm. The study found that the adsorbent performance can be improved by combining chemical and physical activation at temperatures ranging from 500 to 800 oC. KTKOH and KTKH3PO4 at 700 oC increased the adsorbent's qm and surface area. The maximum adsorption capacity and surface area were achieved of KTKOH700 and KTKH3PO4700 at a higher temperature than KTK. The study found that the optimal condition for adsorption capacity was achieved for KTKOH700, resulting in a maximum adsorption capacity value of 44.47 mg/g and a surface area of 269.74 m2/g, KTKH3PO4700 activation resulted in a qm of 59.55 mg/g and A of 427.26 m2/g. The kluwak shell carbon had a maximum adsorption capacity value of 30.75 mg/g and a surface area of 166.21 m2/g. AbstrakKarbon tempurung kluwak (KTK) merupakan adsorben ramah lingkungan yang berasal dari biomassa buah kluwak. Penelitian ini bertujuan untuk mengetahui pengaruh aktivasi fisika pada karbon tempurung kluwak teraktivasi KOH (KTKOH) kisaran suhu 500 – 900 oC dan membandingkan dengan KTK teraktivasi H3PO4 (KTKH3PO4) dan KTK. Kinerja adsorben ditentukan melalui penentukan kapasitas adsorpsi maksimum (qm) Methylene Blue (MB) menggunakan persamaan langmuir dan luas permukaan metode Brunnaeur Emmet and Teller (BET). Isotherm adsorptionMethylene Blue sistem batch selama 90 menit, kecepatan pengadukan 220 rpm, 0.25-gram adsorben dan 50 ml pada 6 konsentrasi MB range 60-200 ppm. Hasil penelitian menunjukkan bahwa kombinasi aktivasi kimia dan aktivasi fisika pada suhu 500 – 800 oC dapat meningkatkan kinerja adsorben. Aktivitasi KTKOH dan KTKH3PO4 pada 700oC juga meningkatkan qm serta luas permukaan adsorben. Kapasitas adsorpsi maksimum dan luas permukaan untuk KTKOH700 dan H3PO4700 lebih tinggi dibandingkan KTK. Kondisi optimal penelitian bahwa kombinasi aktivasi KTKOH700 memiliki nilai kapasitas adsorpsi maksimum 44.47 mg/g dengan luas permukaan 269.74 m2/g dan KTKH3PO4700 didapatkan qm sebesar 59.55 mg/g serta A seluas 427.26 m2/g. Nilai qm 30.75 mg/g dan A sebesar 166.21 m2/g untuk karbon tempurung kluwak.
