in the early stages, which is influenced by the availability of nutrients and plant growth regulators. The use of manure as a source of organic matter and natural Plant Growth Regulators (PGRs) is expected to enhance vegetative growth. This study aimed to determine the effect of manure application and natural PGRs on the vegetative growth of cayenne pepper and to identify the treatment that produces the best growth.The research was conducted from December to January 2026 at the land of the Kopbun Suka Tani Sejahtera Business Research Center, Kota Juang District, Bireuen Regency. The study used a factorial Randomized Block Design (RBD) with a 4 × 3 pattern and three replications. The first factor was the dosage of manure consisting of 0 kg (control), 1 kg, 1.5 kg, and 2 kg per plant. The second factor was the type of natural PGR, consisting of shallot extract, rice water, and coconut water. The observed parameters included plant height, number of leaves, leaf width, and number of branches at 15, 30, and 45 days after planting (DAP). Data were analyzed using the F-test and continued with the Honestly Significant Difference (HSD) test at a 5% significance level if the results were significant.The results showed that manure application had no significant effect on all vegetative growth parameters up to 45 DAP. The application of natural PGRs also showed no significant effect at 15, 30, and 45 DAP, as well as on other parameters. There was no significant interaction between manure and natural PGRs on all observed parameters.

o improve productivity, which remains fluctuating due to suboptimal cultivation practices. The research was conducted from February to March 2026 at the experimental field of the Pusat Riset Bisnis Kopbun Suka Tani Sejahtera, Kota Juang District, Bireuen Regency, using a factorial Randomized Block Design (RBD) of 4 × 3 with three replications. The first factor was the dosage of manure (control, 1 kg/plant, 1.5 kg/plant, and 2 kg/plant), while the second factor was the type of natural PGR (onion extract, rice water, and coconut water). Data were collected through direct observations on several parameters, including number of fruits, fruit weight, fresh biomass weight, root fresh weight, and root length, and were then analyzed to determine the effects of treatments and their interactions.
The results showed that certain doses of manure had a significant effect on increasing yield and root growth, while natural PGRs were able to enhance flowering, reduce flower drop, and accelerate fruit formation. The interaction between both treatments indicated that the optimal combination produced higher results compared to single treatments. The novelty of this study lies in the use of a combination of manure and natural PGRs based on local materials as a strategy to improve the generative phase. The implications of this research are expected to serve as a scientific reference for the development of sustainable cultivation techniques, as well as learning material and further research in the fields of agronomy and horticulture.

arch was conducted from April to July 2025 at Mon Jambe Village, Jeumpa District, and the Kopbun Suka Tani Sejahtera Business Research Center, Kota Juang District, Bireuen Regency. The experiment employed a Randomized Block Design (RBD) with four varieties as treatments and three replications, resulting in 12 experimental units. The tested varieties were Rajo, Genie, Bara, and Tetra Hijau. Data were collected through observations of plant height, number of leaves, number of fruits, fruit weight, and fresh biomass weight, and were analyzed using analysis of variance (ANOVA) to determine differences among treatments. The results showed that the varietal factor had a highly significant effect on leaf number and a significant effect on fruit number and fruit weight. The Bara variety exhibited the most adaptive and productive performance under the cocoa alley cropping system, as indicated by superior vegetative growth and yield compared to other varieties. The novelty of this study lies in emphasizing that varietal selection is a key factor in optimizing the utilization of cocoa alley spaces for cayenne pepper cultivation. These findings are expected to provide a scientific basis for developing cayenne pepper cultivation technologies in cocoa alley systems and to serve as a reference for further research on adaptive variety development under such environmental conditions.

ce: PT Berau Coal's 5-year long-term plan document). This increase in production can basically be achieved in 2 (two) ways, namely: 1. This is done by adding heavy equipment such as loading equipment and production transportation equipment so that production capacity becomes greater. 2. This is done by maximizing the productivity of mechanical equipment, namely existing loading and transport equipment. Increasing production capacity by maximizing the productivity of existing mechanical equipment is a relatively cheaper way than adding heavy equipment. Efficiency is the key to increasing the productivity of existing mechanical tools. Based on considerations of the company's need to increase production, one of which is by maximizing the productivity of existing mechanical equipment, this research aims to conduct a study on the productivity of PC1250 loading equipment and HD465 transportation equipment carried out at the Agaru Pit mining block 44-50 at the Samabarata site. PT Berau Coal so that the results of this study can determine the productivity of each mechanical device. The research method is carried out using direct computation, tabular method, and comparison between theoretical and actual and using the theory of calculation equations. Where the supporting data for analysis is in the form of field data as primary data and literature data as supporting (secondary) data. The results of this research study are the productivity of PC1250 loading equipment and HD465 transportation equipment where there are deviation values between actual and theoretical, both positive deviation (the optimum positive deviation between actual and theoretical is 97.3%) and negative deviation (optimum negative deviation between actual and theoretical is -11.8 %).

itcoin menawarkan manfaat seperti transparansi, efisiensi, dan akses keuangan yang lebih luas, terutama di tingkat global. Namun, tantangan besar muncul berupa volatilitas harga yang ekstrem, spekulasi yang berlebihan, dan potensi manipulasi yang sering kali menimbulkan risiko besar bagi para pelaku transaksi. Dalam konteks Islam, prinsip keadilan, kejujuran, dan transparansi menjadi landasan utama dalam aktivitas ekonomi yang bertujuan menciptakan transaksi yang diberkahi dan tidak merugikan pihak mana pun, sebagaimana ditegaskan dalam hadis Al-Bukhari No. 2079.Penelitian ini menggunakan pendekatan kualitatif berbasis studi literatur untuk menganalisis relevansi nilai-nilai etika dalam hadis tersebut terhadap aktivitas ekonomi digital modern. Temuan penelitian menunjukkan bahwa meskipun Bitcoin dan trading digital memiliki potensi manfaat besar, penggunaannya sering melibatkan unsur-unsur yang dilarang dalam syariah, seperti gharar (ketidakpastian), riba (bunga), dan maysir (perjudian). Pengintegrasian nilai-nilai Islam, seperti keterbukaan dan keadilan, menjadi langkah penting untuk menciptakan ekosistem ekonomi digital yang lebih etis dan berkelanjutan. Teknologi seperti smart contracts dapat membantu menjaga transparansi dan meminimalkan ketidakpastian, tetapi tantangan seperti regulasi yang kurang memadai dan sifat transaksi yang anonim masih membutuhkan perhatian khusus. Hadis Al-Bukhari No. 2079 memberikan panduan moral yang relevan untuk memastikan bahwa aktivitas ekonomi digital berjalan sesuai dengan prinsip-prinsip Islam, mendukung keadilan, dan melindungi pelaku ekonomi dari risiko yang tidak diinginkan. Dengan demikian, penelitian ini menegaskan pentingnya penerapan prinsip-prinsip syariah dalam membangun sistem ekonomi digital yang adil, transparan, dan seimbang.
Abstract:Perkembangan aset kripto berbasis teknologi blockchain telah mengubah lanskap kejahatan ekonomi, termasuk tindak pidana pencucian uang (TPPU) yang berasal dari korupsi. Karakteristik aset kripto yang pseudonim, terdesentralisasi,…
ralisasi, dan lintas yurisdiksi menimbulkan tantangan serius bagi efektivitas rezim anti-pencucian uang di Indonesia. Urgensi penelitian ini terletak pada kebutuhan untuk menilai sejauh mana konstruksi hukum TPPU mampu menjangkau aset kripto serta mengidentifikasi hambatan normatif dan praktis dalam penegakan hukumnya. Penelitian ini bertujuan menganalisis konstruksi hukum TPPU terhadap aset kripto dalam perkara korupsi dan mengkaji tantangan penegakan hukum yang dihadapi aparat penegak hukum di era ekonomi digital. Metode penelitian yang digunakan adalah yuridis normatif dengan pendekatan perundang-undangan, konseptual, dan kasus, yang didukung oleh analisis terhadap bahan hukum primer dan sekunder. Hasil pembahasan menunjukkan bahwa secara normatif aset kripto dapat dikualifikasikan sebagai objek TPPU berdasarkan formulasi terbuka mengenai harta kekayaan dalam Undang-Undang Nomor 8 Tahun 2010. Namun, dualisme pengaturan aset kripto, keterbatasan pengaturan teknis pembuktian dan perampasan aset digital, serta rendahnya kapasitas forensik blockchain dan kerja sama lintas negara menjadi hambatan utama penegakan hukum. Penelitian ini menegaskan pentingnya harmonisasi regulasi, penguatan model pengawasan berbasis risiko, serta peningkatan kapasitas institusional agar rezim TPPU mampu berfungsi secara efektif dalam pemberantasan korupsi berbasis pemulihan aset di era transformasi teknologi finansial.
