Abstract

Jati (Tectona grandis) merupakan salah satu jenis tanaman penghasil kayu pertukangan yang penting dan populer diIndonesia. Kebutuhan kayu jati terus meningkat namun belum dapat dipenuhi dari produksi kayu dari hutan tanamanindustri. Alternatif pemenuhan kebutuhan kayu tersebut diperoleh dari hutan rakyat. Dalam rangka peningkatanproduktivitas hasil hutan rakyat maka IPTEK penyediaan bibit unggul sangat diperlukan. Penyediaan bibit unggulyang diperoleh dari benih unggul memerlukan waktu untuk melakukan seleksi pada plot uji keturunan, sehinggapengembangan teknik perbanyakan vegetatif yang tepat adalah solusi yang bisa diterapkan. Strategi yang diperlukandalam penerapan teknik perbanyakan vegetatif diawali dengan pemilihan pohon induk yang baik (pohon superior),pengambilan materi genetik (bahan vegetatif tanaman), pembuatan okulasi, pembangunan kebun pangkas, danproduksi bibit secara masal dengan menerapkan teknik stek pucuk atau kultur jaringan. Melalui uji klon diharapkandapat diperoleh klon-klon unggulan yang adaptif pada lokasi pengembangan serta memiliki produktivitas yang lebihbaik.

Abstract

Bawang merah (Allium ascalonicum. L.) merupakan salah satu komoditas sayuran yang memiliki nilai ekonomis tinggi, baik ditinjau dari sisi pemenuhan konsumsi nasional, sumber penghasilan petani, maupun potensinya sebagai penghasil devisa negara. Penelitian ini bertujuan untuk mendapatkan dosis pupuk organik cair Eco farming dalam meningkatkan pertumbuhan dan hasil tanaman bawang merah varietas bima. Penelitian ini dilaksanakan di Kebun Akademik Fakultas Pertanian Universitas Tadulako dari bulan Januari sampai Maret 2022. Penelitian ini menggunakan Rancangan Acak Kelompok satu faktor yaitu dosis POC yang terdiri dari enam taraf yaitu: 1) kontrol (tanpa pupuk), 2) 28 ml Eco farming, 3) 50 ml Eco farming, 4) 85 ml Eco farming, 5) 115 ml Eco farming, 6) 135 ml Eco farming. Setiap perlakuan diulang tiga kali sebagai kelompok sehingga terdapat 18 satuan percobaan. Masing-masing percobaan diujikan tiga tanaman sehingga terdapat 54 polybag. Data dianalisis dengan ANOVA dan dilanjutkan dengan uji Beda Nyata Jujur. Hasil penelitian menunjukkan bahwa pemberian POC Eco farming pengaruhnya tidak nyata terhadap pertumbuhan dan hasil tanaman bawang merah, dengan kata lain, dosis POC yang dicobakan tidak memberikan respons tanaman yang berbeda. Secara visual tanggapan tanaman tersebut memperlihatkan pertumbuhan yang berbeda, tetapi pemberian POC Eco farming sangat baik. Perlakuan 50 ml l-1 air cenderung lebih baik terhadap komponen pertumbuhan (tinggi tanaman, jumlah daun) dan hasil (diameter umbi), akan tetapi perlakuan POC 85 ml l-1 air berpengaruh lebih baik pada berat segar dan berat daun segar, pemberian POC 115 ml l-1 air berpengaruh lebih baik pada jumlah umbi per tanaman dan berat kering umbi per tanaman, pemberian POC 135 ml l-1 air lebih baik pada berat basah umbi per tanaman dan total padatan terlarut.

Abstract

AbstractIndonesia's mining industry, encompassing coal, nickel, gold, and other resources, is crucial to its economy. However, this research aims to investigate the multifaceted economic impact of mining activities on coastal communities. Findings reveal both positive and negative consequences. Positively, mining generates employment, increases local income, stimulates business, and enhances purchasing power. Conversely, it triggers environmental degradation, including murky waters, coral reef damage, and mangrove ecosystem disruption, as well as harm to public infrastructure, causing floods and clean water scarcity. From an Islamic economic standpoint, these mining practices in the coastal area of Bungku are inconsistent with Quranic and Hadith teachings and violate ethical principles governing resource management.AbstrakIndonesia adalah salah satu negara yang memiliki industri pertambangan seperti batu bara, nikel, emas, perak, tima, dan minyak bumi lainnya. Pertambangan di Indonesia tersebar diberbagai wilayah baik darat mapun laut. Sehingga industri pertambangan Indonesia mampu berkontribusi terhadap pertumuhan ekonomi, serta mampu memberikan dampak ekonomi terhadap masyarakat. Adapun tujuan dari penelitian ini adalah untuk mengeksplorasi dampak ekonomi pertambangan terhadap masayarakat pesisir baik dampak positif maupun dampak negatif. Adapun metode yang dugunakan dalah pendekatan kualitatif dengan metode pengumpulan data berupa observasi, wawancara dan dokumentasi. Hasil penelitian ini menunjukkan bahwa pertambangan memberikan dampak ekonomi positif dan negatif. Damapak positif pertambangan yang ada di bungku pesisir adalah terbukanya lapangan kerja, meningkatnya pendapatan masayarakat, terjadi peningkatan penjualan terhadap pelaku usaha, daya beli masyarakat yang semakin tinggi. Dampak negatif dari pertambangan tersebut adalah terjadinya kerusakan alam, mangakibatkan air laut keruh, merusak terumbu karang, dan merusak ekosistem hutan bakau, rusaknya jalan umum, mengakibatkan banjir dan kekurangan air bersih. Dalam prespektif ekonomi islam melihat bahwa eksplorasi tambang yang ada di bungku pesisir tidak sesuai dengan pesan al-qur’an dan hadis nabi serta melanggar nilai-nilai etika dalam pengelolaan sumber daya alam.

Abstract

This study aims to analyze the perceptions of property developers towards the practice of murabaha contract KPR financing in Islamic banking in Kendari City. Qualitative research with an explanatory approach with an in-depth interview method with informants, namely Islamic property developers who run a house buying and selling business in Kendari city, resulted in research conclusions showing that Islamic property developers perceive the practice of murabaha contract KPR financing in Islamic banking to contain several problems. From the aspect of the perpetrator, it is considered that it does not fulfill the pillars of buying and selling; when the transaction agreement, the fact that a house has been sold that has not been owned, financing by the bank is more accurately called a loan contract than a sale and purchase so that the margin is more like usury; the use of the house (the object of buying and selling) as collateral has violated the principle of transferring ownership; late fees are the same as usury; and the application of life and fire insurance contains gharar, speculation, violates the principles of tabarru' and dhaman, and there are two contracts in one transaction.

Abstract

Qisya Buah Andonohu is a fruit sales business whose sales process uses an offline and online buying and selling system. Buying and selling itself is an activity of exchanging goods for money, by relinquishing property rights from one to another. Meanwhile, online buying and selling is a buying and selling contract carried out using electronic means as a medium. When buying and selling activities take place in order to realize a good and honest transaction, it is best for the seller and buyer to apply khiyar in their buying and selling. Where khiyar is the perpetrator's right to choose to continue or cancel the transaction. In transaction activities there will definitely still be problems, the same thing happens in the buying and selling system at Qisya Buah Andonohu. The situation where buyers find that the fruit they have purchased is damaged or defective, this cannot be avoided considering that no matter how good or good the seller is at making sales, there will definitely be times when things will not be in accordance with the desired wishes. So the existing problems make it important to implement khiyar. Based on the background description, the problems that can be formulated are 1) what type of khiyar is applied at Qisya Buah Andonohu, and 2) how is khiyar applied at Qisya Buah Andonohu. This research uses a qualitative descriptive research method, the data collected is based on the results of observations, interviews and documentation carried out by researchers. The results of this research are that the buying and selling system carried out at Qisya Buah Andonohu, whether buying and selling offline or online, has implemented three types of khiyar in its buying and selling system. The Khiyar that have been applied to the buying and selling system at Qisya Buah Andonohu are Khiyar Majlis, Khiyar 'Aib, and Khiyar Terms.

Abstract

This study aims to analyze the implementation of the Merdeka Curriculum and its relationship with the development of students’ self-regulated learning (SRL). Employing a descriptive qualitative approach with a case study method, data were collected through in-depth interviews, participatory observation, and documentation at a senior high school in OKU Regency. The findings reveal that the Merdeka Curriculum encourages active student engagement through project-based learning, reflection, and differentiated strategies. Its implementation provides space for students to set learning goals, monitor progress, and evaluate outcomes independently. A positive correlation is found between the curriculum and the development of SRL skills, especially among students who receive strong support from teachers and their learning environment. However, disparities persist due to differences in social background and teachers’ pedagogical readiness. The study concludes that the Merdeka Curriculum holds great potential in shaping autonomous lifelong learners, provided that systemic support is strengthened through teacher training, structured reflection practices, and school-family collaboration.
