Through a qualitative approach involving document analysis and field observations, the study identifies potential legal issues arising from discrepancies between planned specifications and actual implementation. The findings emphasize the importance of legal oversight and standardization in minimizing disputes and ensuring the integrity of building construction. Recommendations are proposed to strengthen the integration of legal considerations in technical planning and execution stages of similar future projects
Role of effective microorganisms on broiler performance and odor emission from litter in broiler chicken production
Full text linkPoultry production is a reliable animal protein source used in different communities. Malodor emitted
from poultry houses limits their production and significantly contributes to air pollution. Mitigations
are thus required to make broiler chicken production more environmentally friendly and productive. This
study investigated the role of effective microorganism (EM) on broiler performance and odor emission
from litter in broiler chicken production. A total of 180-day-old chicks were divided into four treatments:
T0 (without EM-supplementation), T1 (EM-supplemented in water), T2 (EM-supplemented in feed), and
T3 (EM-supplemented in water+feed), with three replicates of 15 birds each. Data on broiler performance,
including water intake (WI), feed intake (FI), average weight gain (ADG), feed conversion ratio, and
carcass characteristics, were measured and analyzed using one-way ANOVA in SPSS (version 25).
Malodor agents were characterized by using gas chromatography. Significant (p<0.05) increase in WI
and FI was delayed among chickens with EM treatments until 4th- 6th and 5th – 6th weeks, where T0
had lower (p<0.05) FI and WI, respectively. T3 had the highest (p≤0.05) increased ADG at the 5th and
6th weeks. Heart, wing, thigh, girth, and live weight did not differ (p>0.05) among treatments, while T0
had higher (p<0.05) liver and gizzard weight compared to the estimates from other groups. T0 recorded
higher (p<0.05) gases, emitted from grower to finisher, compared with starter. EM treatment decreased
(p<0.05) the number of gases emitted, with T3 recorded as the lowest. Thus, EM applications may alter
the emission of odor-causing compounds in the broiler chicken litter without compromising its
performance
Geological Study of Groundwater Using Design Investigation Survey in Amdasa Village, Tanimbar Islands District
Full text linkWater is a primary human need that must be met, but overtime the rate of population growth, the need for water in Amdasa Village, Wertamrian District, Tanimbar Islands Regency is decreasing. Increased water use is sometimes not accompanied by the management of new water sources due to the lack of information about the potential of groundwater sources. Geoelectric surveys will provide potential difference values, current strength, and rock specific resistance values. The value of the rock's specific gravity is then further processed to obtain the value of the specific gravity of each rock layer. The research location has good aquifer potential indicated by the discovery of aquifer layers at shallow depths from the surface of 6 meters and up to 13 meters with various aquifer thicknesses and groundwater well design with a drilling depth of ± 16 meters for points 01 and 03
Nickel Laterite Resource Estimation Using Inverse Distance Weighted (IDW) and Ordinary Kriging (OK) Methods in East Luwu Regency, South Sulawesi, Indonesia
Full text linkNickel is a major mining commodity in Indonesia with abundant reserves, especially in Sulawesi which contributes to the national economy through the stainless steel and electric vehicle sectors. This study aims to analyze the estimation of nickel laterite resources in East Luwu Regency using the Inverse Distance Weighted (IDW) and Ordinary Kriging (OK) methods to analyze the quality and effective methods for estimating nickel laterite resources. The data used were 2.616-grade samples for each borehole interval and analyzed through descriptive statistics, variogram fitting, estimation model building, and laterite nickel resource estimation analysis. The estimation results of the IDW method with Cut-off Grade (COG) showed the volume and tonnage acquisition in the limonite zone of 4.593.710 m3, 5.896.667 tons, while in the saprolite zone of 5.058.249 m3, 6.317.770 tons. The Ordinary Kriging (OK) method shows the acquisition of volume and tonnage in the limonite zone of 4.602.227 m3, 6.203.349 tons, while in the saprolite zone of 5.674.171 m3, 6.647.641 tons. Based on the estimation results, the OK method obtains larger volume and tonnage results than the IDW method. This happens because the OK method uses the principle of spatial correlation of data. It not only focuses on the closes
Resolving Medical Disputes: Lessons from U.S. Arbitration for Indonesia’s Legal Framework
Full text linkArbitration serves as a dispute resolution method that offers notable benefits, especially in cases related to medical issues. In contrast, other methods such as litigation are often seen as less effective, while mediation lacks executory power due to the absence of legal enforceability, making agreements vulnerable to cancellation. In Indonesia, arbitration has not yet been adopted for resolving medical disputes, as specific technical regulations are still needed to guide relevant institutions and establish effective mechanisms. This research highlights the importance of implementing arbitration in Indonesia’s medical dispute resolution framework, using a comparative analysis of practices in the United States. Employing normative legal research with qualitative data analysis and comparative examination of international legal practices, the findings reveal that arbitration offers a binding and final resolution, making it a highly effective approach for handling medical disputes. To facilitate its adoption in Indonesia, comprehensive technical regulations and a legal framework—similar to the United States’ Uniform Arbitration Act (UAA), which outlines arbitration requirements for individual states—are necessary
Legal Reforms in Indonesia’s Financial Sector on Institutional Relations between Bank Indonesia and the Government
Full text linkLegal reform in the financial sector has an important role to play in preparing Indonesia a Golden Indonesia in 2045. The financial sector is very important strategic in the development and welfare Indonesia, supporting its sustainable economic development. Strengthening institutional functions and tasks as well as coordination among ministries and institutions, in this case between the central bank and the government, are essential in order to increase financial system resilience and economic growth. This study analyses financial sector legal reforms that impact institutional relations between central banks and governments by conducting comparative studies of the United States, Japan, Australia, and Thailand. This research also has been updated to present the implications of legal reform in the financial sector on Bank Indonesia's expanding duties and authorities to support a sustainable economy through the enactment of Law Number 4 of 2023 concerning the Development and Strengthening of the Financial Sector. The results of this study show that with the legal reform in the financial sector, there is a new perspective related to Bank Indonesia's independence, which has been adjusted through the adoption of a policy mix prioritising monetary policy. Fiscal authority does not become superior but accommodative as long as it does not conflict with monetary policy interests. The institutional relationship between Bank Indonesia and the government using a policy mix pattern that emphasizes aspects of monetary policy harmonization based on other policy paradigms that are in line with safeguarding broader economic interests
Applying Balanced Scorecard in Evaluating Performance: Evidence from a Food Retailer
Full text linkMeasuring employee performance through a balanced scorecard is crucial for providing a comprehensive view of an organization's effectiveness and strategic alignment. The Balanced Scorecard (BSC) is considered an instrument that can be used to effectively measure employee performance over a specific period of time. Performance appraisal not only helps companies determine the potential for human resource development but also improves employee motivation and productivity. Therefore, this study aims to empirically test and analyze employee performance measurement based on the balanced scorecard at the PHD Makassar Store. This study is a quantitative study. The population used is all employees of the PHD Makassar Store, with a sample size of 33 using the non-probability sampling method. The results of the study indicate that job satisfaction and employee turnover variables do not affect human resource performance at the PHD Bawakareng Store. Inversely, employee training and employee productivity variables affect human resource performance. This indicates that the comparison between employee input and output is running well
Cost and Trend Analysis of Sago Processed Businesses in North Luwu and Palopo City, South Sulawesi Province
Full text linkThis study investigates sago-based food processing businesses' cost structure, profitability, and
sustainability trends in North Luwu and Palopo City, South Sulawesi, Indonesia. Despite sago’s
strategic role as a traditional food and a climate-resilient crop, the industry faces declining raw
material availability, low farmer income, and limited technological adoption. Using a combined
qualitative-quantitative descriptive approach, including structured surveys and focus group
discussions (FGDs), this research provides a detailed cost and trend analysis of micro and small-
scale enterprises producing local sago foods such as bagea, dange, and kapurung. The findings
reveal that while these businesses remain economically viable—with R/C ratios above 1.0 and the
dange business reaching 2.1—profitability is constrained by small-scale operations, high input
costs, and inadequate support systems. This study fills a critical research gap by shifting focus from
upstream sago cultivation to downstream enterprise viability, offering a rare empirical insight into
the dynamics of traditional food microenterprises in Indonesia. The novelty of this research lies in
its integrated assessment of cost efficiency, scale potential, and policy implications. It proposes
strategic interventions including modernizing processing technologies, strengthening farmer-
producer linkages, and scaling up through cooperative models. The results provide actionable
recommendations for local governments and agribusiness stakeholders aiming to revitalize
indigenous food sectors. Future research should explore the design of sustainable enterprise
clusters, examine consumer preferences for sago-based products, and evaluate the long-term
impacts of technological and institutional interventions on sago industry resilience
Durability and Sustainability Assessment of Concrete Incorporating Sea Water and Sea Sand as Alternative Mixing Materials
Full text linkThe increasing scarcity of freshwater and river sand resources has prompted the exploration of marine materials as sustainable alternatives in concrete production. This study investigates the durability and sustainability performance of concrete mixtures prepared using sea water and sea sand as partial replacements for conventional mixing components. Experimental evaluations were conducted to examine the compressive strength, chloride penetration, water absorption, and microstructural characteristics of the concrete specimens. The results revealed that, while sea water and sea sand mixtures slightly reduced early-age strength compared to conventional concrete, they demonstrated satisfactory long-term performance and acceptable durability under marine exposure conditions. Moreover, the life cycle assessment (LCA) indicated that the use of locally available marine resources significantly reduces environmental impacts associated with freshwater extraction and river sand mining. Therefore, incorporating sea water and sea sand in concrete represents a promising approach toward sustainable construction, particularly in coastal and island regions where freshwater and natural aggregates are limited
