Abstract

Tomat merupakan salah satu sayuran yang multiguna dan memiliki nilai ekonomi yang tinggi. Saat ini permintaan tomat tidak sebanding dengan produksi tomat yang di kembangkan. Penelitian ini bertujuan untuk mengidentifikasi karakteristik fisik dan kimia tanah dataran rendah yang mendukung pertumbuhan tanaman tomat di Kiko. Metode yang digunakan adalah survei dan pengambilan sampel tanah menggunakan sistem diagonal pada kedalaman 0–40 cm, selanjutnya dilakukan analisis laboratorium meliputi sifat fisik tanah dan kandungan hara. Hasil penelitian menunjukkan tanah tersebut memiliki kandungan bahan organik yang rendah, sebagian besar tekstur tanah berkategori lempung berdebu, kadar air rata-rata 26,47% yang tergolong rendah, berat jenis berkisar antara 2,58-2,65 g/cm³, dan berat volume berkisar antara 1,50-1,60 g/cm³. Porositas tanah berkisar 40,7%-47,6%, tergolong rendah, sedangkan nilai permeabilitas tanah mencapai 2,76 cm/jam yang termasuk kategori rendah. Kadar NPK tidak mencapai jumlah rata-rata yang disyaratkan. Berdasarkan hasil penelitian ini, dapat disimpulkan bahwa kualitas fisik dan kimia tanah memiliki peranan yang sangat penting dalam pengelolaan tanah secara optimal untuk mendukung pertumbuhan tanaman tomat di Kiko.

Abstract

This study focuses on the application of the System-Generalized Method of Moments (System-GMM) statistical approach to analyze the determinants of poverty in 22 districts/municipalities in East Nusa Tenggara Province (NTT) over the period 2015–2019. The GMM method is employed to address issues of endogeneity, heterogeneity, and data persistence that are commonly encountered in regional socio-economic studies. By utilizing internal instruments, this approach enables more valid and robust parameter estimation. The panel data, obtained from the Central Bureau of Statistics, includes variables such as the Human Development Index (HDI), Open Unemployment Rate (OUR), and electrification ratio. The estimation results show that HDI has a negative and significant effect on poverty, with short-term and long-term elasticities of -0.984 and -2.244, respectively. The OUR has a positive and significant effect on poverty, with elasticities of +0.016 (short-term) and +0.036 (long-term), while the electrification ratio also shows a negative and significant effect, with elasticities of -0.035 and -0.081. These findings affirm that the application of the System-GMM method provides a more accurate depiction of the causal relationships among the determinants and supports evidence-based policymaking for poverty alleviation in structurally challenged regions such as NTT.

Abstract

Bokashi is an anaerobically fermented organic fertilizer whose quality depends on the balance between carbon-rich and nitrogen-rich feedstocks. This study evaluated five bokashi formulations prepared from different proportions of leaf straw (JD) and cattle manure (PK), namely: JD100, JD75PK25, JD50PK50, JD25PK75, and PK100. Bokashi was fermented under anaerobic conditions for 21 days and assessed for temperature, moisture content, pH, organic carbon, C/N ratio, total nitrogen, P₂O₅, K₂O, and magnesium (Mg). The experiment was arranged in a Completely Randomized Design, while treatment performance was evaluated using descriptive statistics, including mean ± standard deviation, coefficient of variation, and trend analysis. Results showed that increasing the proportion of manure generally enhanced nutrient availability. Total nitrogen increased from 1.54% in JD100 to 2.72% in JD25PK75, while Mg concentration increased from 3,506 mg kg⁻¹ in JD100 to 10,999 mg kg⁻¹ in PK100. In contrast, straw-dominated formulations maintained higher organic carbon content (27.86%) and more neutral pH conditions (7.7). The C/N ratio declined from 18.10 in JD100 to 8.72 in PK100, indicating greater decomposition and compost maturity. Among the treatments, JD50PK50 exhibited comparatively balanced characteristics, combining relatively high organic carbon, moderate nutrient levels, near-neutral pH (6.8), and a moderate C/N ratio (11.48). These findings suggest that balanced straw–manure mixtures can improve bokashi maturity, nutrient retention, and chemical stability for sustainable organic fertilizer production.

Abstract

This study aimed to evaluate the effects of different types of organic manure on the growth and survival of watermelon (Citrullus lanatus) seedlings cultivated in Vertisol media. The treatments consisted of cattle, goat, and chicken manure, along with a non-fertilized control. Vegetative growth parameters observed included plant height, leaf number, and leaf area, while seedling survival was analyzed using the Kaplan–Meier method and log-rank test. The results showed that manure type significantly affected all vegetative growth parameters. Cattle manure produced the highest vegetative growth performance, followed by the control and goat manure treatments, whereas chicken manure resulted in the lowest growth response. The highest survival rate was observed in the cattle manure treatment (100%), followed by the control (93.75%) and goat manure (87.50%), while chicken manure showed the lowest survival rate (18.75%). Kaplan–Meier curves revealed that the chicken manure treatment experienced the most rapid decline in survival probability from the early observation period. The log-rank test demonstrated that differences among survival curves were statistically significant (log-rank χ² = 41.98; df = 3; p < 0.001), indicating that organic manure type significantly influenced seedling survival during the early nursery stage. Overall, the findings demonstrate that under Vertisol conditions, cattle manure provided the best combination of vegetative growth and survival stability of watermelon seedlings compared with the other treatments.

Abstract

The Consumer Price Index (CPI) is a crucial macroeconomic indicator reflecting regional inflationary pressures. This study aims to compare the performance of Ordinary Least Squares (OLS) and Maximum Likelihood Estimation (MLE) methods in estimating Holt-Winters model parameters for forecasting the CPI of East Nusa Tenggara (NTT) Province. Using monthly data from January 2021 to December 2025, the research evaluates two primary approaches: conventional OLS based Holt-Winters models and the MLE based Error, Trend, and Seasonal (ETS) framework. Model performance was assessed using the Mean Absolute Percentage Error (MAPE). The results demonstrate that the MLE based approach significantly outperforms OLS; the multiplicative ETS model achieved the lowest MAPE of 0.57%, proving far more accurate than the OLS based Holt-Winters models, which yielded error rates exceeding 50%. A 12-month forecast for 2026 projects NTT CPI to increase moderately from 107.38 to approximately 109.54, indicating controlled inflationary pressure. This study affirms the superiority of the MLE approach in generating precise parameters for economic data exhibiting seasonal patterns.
