Abstract

The earth's surface consists of 71% water, water itself has unique characteristics, both physical and chemical. The Kampar river basin has a direct influence on the quality of groundwater (wells) for the residents of Kampung Baru Salo Hamlet. This is because this area is directly adjacent to the Kampar river, ground water (wells) in every house of the residents of Kampung Baru Hamlet is used for daily needs such as consumption, bathing and washing. Along with rapid population growth, the need for clean water is also increasing. This is one of the problems that occurs in Kampung Baru Hamlet, namely the lack of groundwater (wells) that is clean and suitable for consumption. The research carried out by the author discusses how to design a portable water purifier that is efficient and uses easily available materials. This design was carried out using the Nigel cross method. Data collection was carried out by giving questionnaires to 25 respondents who experienced difficulties with clean well water (fit for consumption). Based on the results of the research that has been carried out, the researchers concluded that portable water purifiers can overcome the problem of lack of clean water that occurs in the community and also that the materials for making them are easy to obtain so that people can make them at home. Based on the results of consumption standard testing, the water produced from this filtration process meets the standard consumption requirements, namely 7 - 9 pH.

Abstract

The use of inorganic fertilizers in cocoa nurseries has a negative impact on environmental sustainability, so it is necessary to optimize organic fertilizers that are proven to be environmentally friendly and can be used sustainably. Therefore, an alternative is needed to substitute organic fertilizers, namely the use of Azolla pinnata compost. Azolla pinnata compost has the potential to substitute the use of inorganic fertilizers N, P, and K because the nutrient content is already available in Azolla pinnata compost. This study aims to determine the minimum dose of Azolla pinnata compost that provides the same growth as inorganic fertilizer (NPK) in enhancing the growth of cocoa seedlings in PMK soil. This study used a non-factorial Completely Randomized Design (CRD) consisting of 5 treatment levels with 4 replications. So that 20 experimental units  were obtained. Each treatment consisted of 3 plant samples so that 60 plants were obtained. The treatments consisted of K0: NPK fertilizer 24 g polybag-1, K1: Azolla pinnata compost 100 g polybag-1, K2: Azolla pinnata compost 150 g polybag-1, K3: Azolla pinnata compost 200 g polybag-1, K4: Azolla pinnata compost 250 g polybag-1. The data obtained from the research results were analyzed statistically using Analysis of Variance (ANOVA). If the treatment had a significant effect, it was continued with the Least Significant Difference (LSD) test at the 5% level using the DSAASTAT application. The results of the analysis of variance showed that the treatment of inorganic fertilizer (NPK) and Azolla pinnata compost had a significant effect on the variables of plant height, stem diameter and leaf chlorophyll. The results of the 5% LSD test showed that treatment with a dose of Azolla pinnata compost of 200 g polybag-1could provide the same growth as the administration of inorganic fertilizer (NPK) with a dose of 24 g polybag-1in cocoa seedlings in PMK soil.

Abstract

Cocoa (Theobroma cacao L.) is an important plantation commodity that contributes significantly to Indonesia’s economy as a major export source after the oil and gas sector. This study aimed to determine the effect of kiambang liquid organic fertilizer (LOF) and cow manure compost on the growth of cocoa seedlings in ultisol soil. The experiment was arranged in a completely randomized design (CRD) with two factors. The first factor was LOF: K0 (without LOF), K1 (120 mL LOF + 880 mL water), K2 (150 mL LOF + 850 mL water), and K3 (180 mL LOF + 820 mL water). The second factor was cow manure compost: S0 (without compost), S1 (200 g/polybag), S2 (250 g/polybag), and S3 (300 g/polybag). Each treatment consisted of three replications, resulting in 48 experimental units with a total of 144 seedlings. The results showed that the application of kiambang LOF at 180 mL + 820 mL water significantly increased seedling height, stem diameter, root volume, and dry weight. Cow manure compost at 300 g/polybag significantly improved all growth parameters, including height, stem diameter, number of leaves, root volume, dry weight, and soil pH. The interaction between kiambang LOF (180 mL) and cow manure compost (300 g/polybag) significantly affected seedling height at 3, 5, and 7 weeks after planting (WAP) and root volume

Abstract

Roads are land transportation infrastructure that includes all parts of the road system, such as connecting structures, complementary buildings, and equipment intended for traffic activities on, above, and below the ground surface, including water surfaces, excluding railways, haul roads, and cable roads. This research aims to identify the condition of environmental roads in Lereng Village, Kuok District, and to produce a spatial distribution map of the environmental road network. The study applies a survey-based quantitative descriptive method, focusing on describing actual conditions and revealing factual problems found in the field. Primary data were obtained through direct field observations and measurements, while secondary data were collected from related institutions. Geographic Information Systems were selected as the main analytical tool due to their ability to manage spatially referenced data, process complex structures, and efficiently support decision making related to road infrastructure management. The results show that most environmental roads in Lereng Village are in damaged condition, dominated by potholes, longitudinal cracks, and surface deterioration. Several roads are classified as heavily damaged, including Transad Alley 1, Transad Road 2, and other local roads within the village area. These conditions reduce driving comfort and safety for road users and indicate the urgent need for improvement. The mapping results produce an environmental road condition map with priority scores ranging from 9 to 18. Roads with priority values greater than 7 are categorized as requiring routine maintenance, providing a basis for planning maintenance and rehabilitation programs.

Abstract

Degradasi lahan wilayah pertambangan dapat menjadi permasalahan besar jika tidak dikelola dengan baik dan bisa menyebabkan perubahan kondisi alam, fisik, kimia, dan biologi tanah. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh, dosis kombinasi terbaik serta interaksi pemberian biochar sekam padi dan kompos kotoran ayam terhadap sifat kimia tanah bekas tambang emas dalam percobaan inkubasi. Penelitian ini dilakukan dengan metode eksperimen menggunakan Rancangan Acak Lengkap (RAL) faktorial dengan 3 ulangan. Faktor pertama adalah biochar sekam padi (B), yang terdiri dari 3 taraf (B0: 0, B1: 300, B2: 400 g/polybag) dan faktor kedua adalah kompos kotoran ayam (K), yang terdiri dari 3 taraf (K0: 0, K1: 300, K2: 400 g/polybag). Apabila data yang didapat berpengaruh nyata, maka dilanjutkan dengan Duncan Multiple Range Test taraf 5%. Hasil penelitian menunjukkan perlakuan biochar sekam padi berpengaruh nyata terhadap parameter pH tanah, N, P, K, C-organik dan Pb. Dosis terbaik perlakuan biochar sekam padi yakni 400 g/polybag. Perlakuan kompos kotoran ayam berpengaruh nyata dalam menaikkan nilai pH tanah, N, P, dan K serta berpengaruh tidak nyata terhadap parameter C-organik. Dosis terbaik perlakuan kompos kotoran ayam yakni 400 g/polybag. Terjadi interaksi yang berpengaruh nyata perlakuan biochar sekam padi dan dosis kompos kotoran ayam terhadap parameter pH tanah, N, P, K, dan Pb. Tidak terjadi interaksi perlakuan biochar sekam padi dan kompos kotoran ayam terhadap parameter C-organik. Dosis terbaik yakni 400 g/polybag biochar sekam padi + 400 g/polybag kompos kotoran ayam atau setara dengan 900 ton/ha.
