Abstract

This study aims to develop an integrative approach between water quality modeling using QUAL2Kw software and the Multi-Criteria Decision Analysis (MCDA) method with PROMETHEE software to support the formulation of policies for sustainable river water quality standards. The study was conducted on the Cileungsi River, West Java, with key parameters of BOD, COD, and TSS. Modeling was carried out in four tiered scenarios representing existing conditions and quality standards targets of classes IV, III, and II, thus providing a basis for designing technical interventions such as reducing point source and non-point source pollutant loads, increasing upstream discharge, and improving upstream water quality. Based on the results of iterations and model observations, six policy criteria (K1–K6) and twelve program alternatives (P1–P12) were obtained to achieve river water quality standards. PROMETHEE analysis was used to determine program priorities based on stakeholder preference weights. The results of the study show that the integration of QUAL2Kw–PROMETHEE is able to provide a more measurable scientific and policy basis, with the main priorities being the development and improvement of IPAL performance, control of non-point sources, and an increase in river base discharge. This approach has the potential to be applied as an evidence-based policy decision-making model in river water quality management in Indonesia.

Abstract

Dampak perkembangan Kawasan Bandung Utara di zona tidak sesuai untuk perumahan meningkatkan pertumbuhan jumlah penduduk dan perekonomian masyarakat, menurunkan kualitas lingkungan yang ditandai dengan menurunnya tingkat pelayanan jalan dan kualitas udara. Penelitian ini bertujuan untuk mengevaluasi  pola perubahan volume lalulintas  dan tingkat pelayanan jalan; mengetahui hubungan pola perubahan volume lalulintas dan pencemaran udara terhadap indeks kualitas lingkungan; dan mengusulkan pilihan kebijakan dalam pengelolaan lalu lintas. Pengumpulan data primer diperoleh dari pengamatan fisik kimia udara dan lalu lintas dari lapangan serta data sekunder dari instansi-instansi berwenang. Analisis sistem dampak pembangunan perumahan terhadap kinerja jalan dan pencemaran udara menggunakan software Excel for Windows 2003 dan Powersim versi 2.5C. Hasil yang diperoleh adalah : (i) peningkatan volume lalu lintas di sepanjang koridor  jalan serta menurunnya kinerja tingkat pelayanan jalan dengan kategori D,E, F (>0,85), (ii) penurunan indeks kesehatan lingkungan (peningkatan jumlah kematian dini akibat pencemaran udara); (iii) pengelolaan dampak lingkungan dengan memprioritaskan kebijakan perbaikan kapasitas jalan,rasio volume dengan kecepatan kendaraan melalui penambahan lajur jalan dan lebar jalan.

Abstract

This study aims to determine the reaction kinetics of the rice husk pyrolysis process by analyzing the characteristics of the Thermogravimetry Analysis (TGA) curve. Characteristics of the TGA Curve describes the process of losing mass to the temperature in the pyrolysis process with various stages of material phase changes due to the heating process. The pyrolysis process is influenced by temperature, time, and heating rate, so by analyzing the temperature, time and heating rates, the reaction kinetics will be obtained. The kinetic reaction of the pyrolysis process based on the Arrhenius equation, the speed of the decomposition reaction is influenced by changes in mass or mass fraction per unit time. Exponential factor value (A) will affect the speed of reaction of the pyrolysis process, the greater the value of A, the greater the reaction speed and vice versa. Value (A) in the pyrolysis process of HCl washed and heated rice husk, the value is smaller when compared with the value of A process of rice husk pyrolysis without washing and heating.

Abstract

One of the fundamental problems faced by MSMEs is limited capital. Although MSMEs may have received financing, many still encounter obstacles in elevating their business category. Among these factors are financial literacy and financial inclusion. Therefore, in this study, the data were collected through questionnaires and interviews with 113 MSMEs that have received KUR financing from BSI in the Bogor Area, using purposive sampling. The analytical methods used in this study include both qualitative and quantitative descriptive analysis. This includes classical assumption tests, regression model estimation, and hypothesis testing (t-test). Strategy development uses the Internal Factor Evaluation (IFE) and External Factor Evaluation (EFE) matrices, SWOT analysis and QSPM. The QSPM analysis identifies three top-priority strategies that most significantly support MSMEs in upgrading their business class after receiving KUR financing from BSI in the Bogor Area: (1) enhancing financial inclusion by providing easier access to banking services, both savings and financing. (2) improving the reputation and role of KUR in assisting unbankable MSMEs to become bankable and move up in business class. (3) increasing financial literacy among customers to encourage the use of BSI bank accounts for transactions, including digital transactions.

Abstract

Fluctuations in cayenne pepper prices in local markets are difficult to predict and often create uncertainty in farmers' decision-making. This study analyzes cayenne pepper price dynamics and develops a Random Forest-based prediction model using weekly price data (2021–2024) from four markets in East Lombok Regency: Pancor, Aikmel, Paok Motong, and Sakra. Predictor features included lagged prices (24 weeks), rolling mean and standard deviation (4-, 8-, and 12-week windows), and seasonal sine–cosine transformations. The dataset was split chronologically into training (80%) and testing (20%) sets to preserve temporal dependencies. The model achieved R² values of 0.86–0.93, with MAE of IDR 2,657–4,206 per kg and RMSE of IDR 3,519–4,946 per kg. It captured general price trends and seasonal patterns well but showed limited accuracy in predicting extreme price spikes, likely due to the inherent limitation of tree-based algorithms in extrapolating beyond historical training ranges and the absence of external variables such as supply volume. These findings indicate that cayenne pepper price dynamics follow learnable historical patterns, and the model has potential as a data-driven decision-support tool to help reduce, though not eliminate, market uncertainty and support local food security
