Abstract

Cocoa is a vital plantation commodity in Indonesia, but its productivity is hindered by suboptimal seedling quality. This study aimed to evaluate the vegetative growth response of cocoa seedlings to various combinations of nitrophenol compound concentrations and NPK fertilizer doses, and to identify the optimal treatment combination. The experiment was conducted at the Experimental Garden of the Faculty of Agriculture, Pasir Pengaraian University, Riau, from June to October 2025, using a Randomized Complete Block Design (RCBD) with a factorial arrangement. The first factor was the concentration of nitrophenol compounds (0, 1.5, 3.0, and 4.5 ml/L), and the second factor was the NPK fertilizer dose (0, 5, and 10 g per polybag). The parameters measured included plant height, stem diameter, leaf number, root volume, and dry weight. Data were statistically analyzed using an F-test (ANOVA) at the 5% significance level with PKBT-STAT 3.2, followed by the Honestly Significant Difference (HSD) test at the 5% level. The results indicated a highly significant interaction (P < 0.01) between nitrophenol compounds and NPK fertilizer on all measured parameters. The combination of 4.5 ml/L nitrophenol compounds and 10 g/polybag NPK fertilizer produced the best results, with a plant height of 46.00 cm, 17 leaves, a stem diameter of 0.69 cm, a root volume of 6.50 ml, and a dry weight of 4.38 g. These findings demonstrate that increasing both the concentration of the nitrophenol compound and the fertilizer dose synergistically enhances the vigor and quality of cocoa seedlings.

Abstract

One of the companies engaged in the organic fertilizer industry is CV. Riau Jaya Perdana Tambusai which is located in Rokan Hulu Regency. CV. Riau Jaya Perdana Tambusai, established in 2020 in Desa Talikumain, Kecamatan Tambusai, Kabupaten Rokan Hulu, Riau, is an organic fertilizer distribution company that plays a role in supporting sustainable agriculture. As a developing company, its main challenge is to improve distribution and marketing efficiency to remain competitive in the market. Therefore, the company needs to optimize operational costs and expand its marketing network. Based on this, this study aims to analyze the distribution of organic fertilizer marketing at CV. Riau Jaya Perdana Tambusai and assess its efficiency level. This research adopts a case study approach with descriptive analysis to explain the organic fertilizer marketing distribution patterns at CV. Riau Jaya Perdana Tambusai. Marketing efficiency is analyzed using cost calculation formulas, marketing margins, and farmer share to determine the extent to which organic fertilizer distribution operates efficiently. The findings indicate that the company employs three distribution patterns: zero-level (direct purchase by consumers from CV), level I (through distributors), and level II (involving agents and distributors). The analysis shows a marketing efficiency rate of 2%, classified as efficient (<50%), particularly in level I, despite incurring fuel costs. Meanwhile, level II proves to be more efficient as it does not require additional marketing costs.

Abstract

Credit payment delinquency is a problem frequently encountered by Village-Owned Enterprises (BUMDes) and has the potential to disrupt the sustainability of village financial management. This condition also occurs at BUMDes Rambah Muda Jaya in Rambah Muda Village, Rambah Hilir Subdistrict, Rokan Hulu Regency. The objective of this study is to identify the characteristics of customers who experience credit arrears at BUMDes Rambah Muda Jaya and to analyze the factors that influence the duration of customer credit arrears. The research employed a quantitative method with a survey approach, using primary data collected through questionnaires administered to 21 respondents who were delinquent credit customers. Data analysis techniques included validity testing, reliability testing, classical assumption tests, and multiple linear regression analysis. The results show that the majority of delinquent credit customers are male (90%), within the age range of 25–35 years (70%), have an elementary school level of education (43%), and work as oil palm farmers (81%). The regression analysis indicates that the Internal Debtor factor (X1) and the External Financial Institution factor (X3) have a positive and significant effect on credit payment delinquency, while the Internal Financial Institution factor (X2) does not have a significant effect. Simultaneously, the three variables are able to explain 73.0% of the variation in customer credit payment delinquency.

Abstract

Sektor pertanian memiliki peran penting dalam perekonomian wilayah Kabupaten Rokan Hulu sebagai daerah dengan karakteristik agraris. Penelitian ini bertujuan untuk menganalisis peran sektor pertanian terhadap perekonomian wilayah meliputi identifikasi sektor basis, kontribusi terhadap PDRB dan penyerapan tenaga kerja, daya saing sektoral, serta dampak pengganda ekonomi. Penelitian menggunakan pendekatan kuantitatif dengan data sekunder berupa PDRB atas dasar harga konstan dan data ketenagakerjaan Kabupaten Rokan Hulu dan Provinsi Riau yang bersumber dari Badan Pusat Statistik. Metode analisis meliputi Location Quotient (LQ), analisis kontribusi, analisis multiplier effect, dan Shift Share. Hasil penelitian menunjukkan bahwa sektor pertanian memiliki nilai rata-rata LQ > 2 yang menandakan sektor basis dengan keunggulan komparatif tinggi. Kontribusi sektor pertanian terhadap PDRB daerah mencapai 54% pada periode 2020–2023 dan 53% pada tahun 2024 serta menjadi penyerap tenaga kerja terbesar di wilayah penelitian. Analisis multiplier menunjukkan bahwa sektor pertanian memiliki dampak pengganda yang kuat sehingga mampu mendorong aktivitas ekonomi sektor lain. Selain itu, hasil menunjukkan nilai competitive share positif sebesar 9.314.970,0 yang menandakan Shift Share sektor pertanian memiliki daya saing relatif lebih baik dibandingkan wilayah referensi. Dengan demikian, sektor pertanian terbukti berperan strategis dalam menopang perekonomian wilayah Kabupaten Rokan Hulu dan layak dijadikan sektor prioritas dalam perencanaan pembangunan ekonomi daerah.
