The Department of Environment and Forestry, Pollution and Environmental Damage Control Division, has an active role in monitoring water quality in Riau Province. The rivers that are still monitored ...and managed are Kampar River, Siak River and Indragiri River. Division of Environment Pollution calculates river quality status manually using Microsoft Excel, this is not maximally done since this important information should be processed quickly. Division of water pollution must determine the right calculation to get the results of the water quality status. Because of many calculation formulas set by the government, the commonly used method is the STORET method and the Pollution Index. So, in overcoming the problem of classification, the researcher proposes the use of learning methods that can predict or determine the status of water quality with classification techniques on data mining that is Modified K-Nearest Neighbor (MKNN) which is a modification of K-NN. The calculation of the MKNN algorithm produced the highest accuracy of 85.10% at K = 5 using STORET result data as training data. While, using the Pollution Index data results, the highest accuracy is 76.92% at K = 1. Based on the analysis with attribute analysis, the attributes that influence the determination of river water quality are BOD, COD, NH3, Fecal Coli and Total Coli. This result can be taken into consideration by the Division of Environmental Pollution in the process of overcoming and reducing pollutant overload that exceeds quality standards.

Coleus amboinicus L. leaf (CAL) could reduce the rate of amino acid deamination and protein degradation within the rumen. This phenomenon would hopefully increase the amount of protein that passes ...through the rumen to the abomasum. Therefore, it might improve the digestibility of the ration and then influence the milk yield and quality. The objective of this experiment was to evaluate the effect of extracted CAL within the ration on the ration digestibility, milk yield, and milk quality of Ettawa crossbred (EC) goats. This study used sixteen EC with an average weight of 32.25 ± 3.31 kg and aged 1.5–2.5 years. Experimental goats were fed diets with different CAL extracts: P0, 0% (control); P1, 2% powdered CAL; P2, 2% ethanol-extracted CAL; and P3, 2% water-extracted CAL. The experiment was conducted in a randomized block design with four replication blocks. All variables were statistically analyzed with ANOVA and significances were followed by Duncan’s test. P3 treatment significantly (p<0.05) increased milk yield and milk quality in comparison with control. Unlike the other treatments, P3 treatment was water-extracted CAL that could affect these variables. P3 treatment showed the best result among the four treatments. In conclusion, P3 treatment, the supplementation of 2% water-extracted CAL within the ration, could improve the milk yield up to 30.24% in comparison with the control ration and also improve milk composition, such as milk protein (4.47%), milk casein (3.99%), milk fat (3.85%), and solid nonfat (SNF) (6.53%). The supplementation of water-extracted CAL within ration could improve the milk yield and milk quality of EC.
The economic growth of a region is significantly influenced by various factors, among which investment and consumption are considered pivotal. Despite the considerable focus on these aspects in ...existing literature, there is a noticeable gap in understanding their impact, particularly in the context of Indonesia's Bangka Belitung Islands. This research aims to fill this gap by empirically investigating the multiplier effect of investment on economic growth in this region. By employing the Random Effect Model (REM) on logarithmically transformed data, the study attempts to offer nuanced insights into the relationship between consumption, investment, labor, and economic growth. The findings and their implications are expected to guide policy decisions and stimulate balanced and inclusive economic growth across Indonesia. The findings diverge from certain previous studies that found no significant relationship between investment and economic growth, particularly in regions outside Java. These discrepancies could be attributed to variations in data sources, temporal spans, and methodologies employed across these studies. Additionally, the research underscores the critical role of infrastructure in regional economic growth, echoing the emphasis found in the extant literature. In conclusion, the study reinforces the importance of Consumption and Investment in driving economic growth in the Bangka Belitung Islands. It further urges policymakers to prioritize balanced investment and infrastructure development, especially in regions beyond Java, to encourage more equitable economic growth across Indonesia.
Tujuan penelitian ini adalah untuk mengetahui degradasi neutral detergent fiber (NDF) dan acid detergent fiber (ADF) dan protein kasar (PK) dari rumput raja (RR) secara in vitro menggunakan cairan ...feses sebagai inokulum. Sampel RR diambil dari Fapet Farm Fakultas Peternakan Universitas Jambi, kemudian dipotong-potong dengan ukuran panjang 5 cm kemudian dikering dan digiling dengan ukuran 1 mm mash. Feses dan cairan rumen diambil dari satu ekor sapi berfistula rumen. Sampel kemudian diinkubasi untuk mengetahui degradasi NDF, ADF dan PK. Penelitian ini menggunakan Rancangan Acak Lengkap (5x4) dengan lima perlakuan sebagai berikut A (Cairan rumen (kontrol)), B (Cairan feses), C (Cairan feses dan 2,5% gula), D (Cairan feses, 2,5% gula dan 2,5% urea) dan E (Cairan feses dan 2,5% urea). Hasil percobaan menunjukkan bahwa degradasi in vitro NDF dan ADF dari RR menunjukkan perbedaan nyata (P<0,05). Dapat disimpulkan bahwa penggunaan cairan feses dan penambahan gula sebagai sumber energi dan urea sebagai sumber nitrogen belum optimal yang terlihat dari masih rendahnya degradasi ADF dan PK kecuali NDF jika dibandingkan dengan penggunaan cairan rumen.

There were four treatments of this experiment namely P0: basal diet (control), P1: basal diet added with 2 % of CAL powder, P2:basal diet added with 2 % of CAL extracted with water, P3 basal diet added with 2 % of CAL extracted withethanol. Each sample was incubated for 48 h following the Reading Gas technique methods with slight modification. Gas was collected at 2, 4, 6, 8, 12, 18, 36 and 48 h. The parameters measured were the total gas production (P), potential gas production (b) and rate of gas production (c). The results of this experiment showed that P and b were significant (P<0.05) different. The total gas production was 122.16, 94.78, 122.34 and 62.34 ml/g for P0, P1, P2 and P3 respectively and b was 124.88, 100.13, 117.05 and 80.76 ml/g for P0, P1, P2 andP3 respectively. The value of c was not significant (P>0.05) among four treatments. The value of c was 0.0625, 0.0525, 0.0525 and 0.0425 for P0, P1, P2 andP3 respectively. It could be concluded that the use of water to extract CAL was the best among four treatments.
