Analisis Efektivitas Program Peremajaan Sawit Rakyat (PSR) pada Pekebun Sawit di Kecamatan Silangkitang Kabupaten Labuhanbatu Selatan
Full text linkThe Smallholder Oil Palm Rejuvenation Program (PSR) is a national program that aims to increase the productivity of smallholder palm oil plantations by replanting old and unproductive trees to make them more sustainable and of higher quality. This research aimed to determine effectiveness of the PSR program in Silangkitang District, South Labuhanbatu Regency, through an approach that assesses the suitability of program implementation based on PSR regulations and evaluates the PSR program using the CIPP evaluation model. The research was conducted from September to November 2025. This research is quantitative descriptive with qualitative analysis. Data collection techniques used interviews and questionnaires. The research respondents were selected using random sampling, namely 51 farmers who had participated in the PSR program during the 2019-2025 period. The results of the reseacrh show that the implementation of PSR has not reached the target of 200 ha/year. The realization of rejuvenation is still hampered by farmer administration, land legality issues, the length of the technical recommendation issuance process, and farmers\u27 concerns about losing income while the plants are not yet producing. The implementation of the PSR program still has discrepancies, especially in the plant maintenance stage, such as fertilization and pest control. The dissemination of the PSR program, ongoing guidance and monitoring for farmers by Food Security and Agriculture Agency of South Labuhanbatu District are also not yet optimal. Evaluation effectiveness of the PSR program through the CIPP evaluation model shows that it is effective. However, there are still several aspects of each CIPP component that need to be evaluated further, especially the input aspect, and follow-up is needed to improve implementation of the PSR program so that the program objectives can be achieved optimally.Program Peremajaan Sawit Rakyat (PSR) merupakan program nasional yang bertujuan meningkatkan produktivitas perkebunan kelapa sawit rakyat melalui peremajaan tanaman tua dan tidak produktif agar lebih berkelanjutan dan berkualitas. Penelitian ini bertujuan untuk mengetahui efektivitas program PSR di Kecamatan Silangkitang Kabupaten Labuhanbatu Selatan melalui pendekatan kesesuaian implementasi program berdasarkan regulasi PSR dan evaluasi program PSR menggunakan model evaluasi CIPP. Waktu penelitian dilakukan pada September sampai November 2025. Jenis penelitian ini merupakan deskriptif kuantitatif dengan pendalaman kualitatif. Teknik pengumpulan data menggunakan metode wawancara dan kuesioner. Responden penelitian dipilih secara random sampling yaitu pekebun yang telah mengikuti program PSR selama periode 2019-2025 sebanyak 51 pekebun. Hasil penelitian menunjukkan bahwa pelaksanaan PSR belum mencapai target 200 ha/tahun. Realisasi peremajaan masih terkendala pada administrasi pekebun, ketidaksesuaian legalitas lahan, lamanya proses penerbitan rekomendasi teknis, serta kekhawatiran pekebun kehilangan pendapatan selama masa tanaman belum menghasilkan. Implementasi program PSR masih memiliki ketidaksesuaian terutama pada tahap pemeliharaan tanaman seperti pemupukan dan pengendalian organisme pengganggu tanaman (OPT). Sosialisasi program, pembinaan dan monitoring berkelanjutan bagi pekebun oleh Dinas Ketahanan Pangan dan Pertanian Kabupaten Labuhanbatu Selatan juga belum optimal. Evaluasi efektivitas program PSR melalui model evaluasi CIPP menunjukkan kategori efektif. Namun masih terdapat beberapa aspek dari setiap komponen CIPP yang perlu dievaluasi lebih lanjut terutama aspek input, serta memerlukan tindak lanjut untuk penyempurnaan pelaksanaan program PSR agar tujuan program dapat tercapai secara optimal

Geometric Anisotropic Semivariogram Modelling of Hotspot Confidence Levels in South Matan Hilir Subdistrict
Full text linkThe purpose of this research is to apply geometric anisotropic semivariogram modelling to confidence level of hotspots in South Matan Hilir Subdistrict, Ketapang Regency. The confidence level of hotspot can be used as an indicator of the likelihood of forest and land fires. A higher confidence level indicates a greater certainty that a fire has actually occurred at the hotspot location. The hotspot confidence level is spatial data because it is a random variable with an index location; therefore, the relationships among locations can be represented using a semivariogram model. A geometric anisotropic semivariogram model was employed in this study since the influence of direction exists in the distribution of hotspots. The results present that the exponential semivariogram model is the most suitable to represent the data, with the strongest spatial influence occurring in the north-south direction. Moreover, spatial dependence remains significant at a distance of 0.02027
Zero-Inflated Integer Autoregressive (ZINAR) Approach in Modeling Major Earthquakes in Sumatra Region
Full text linkSumatra is one of the regions in Indonesia with the highest seismic activity due to the convergence of the Indo-Australian and Eurasian plates. Major earthquakes with magnitudes of more than 7 pose serious risks, making it essential to understand their frequency for effective disaster mitigation planning. This study aims to model the frequency of major earthquakes in Sumatra using the Zero-Inflated Integer Autoregressive (ZINAR) model, which accommodates discrete data with excess zeros and temporal dependence. The analysis indicates significant overdispersion and zero inflation, leading to the selection of the ZINAR model as the most suitable approach compared to alternative models such as INAR, NB-INAR, and NB-ZINAR. The ZINAR model demonstrates superior performance in capturing the occurrence patterns of large earthquakes and effectively identifies non-event periods, although its predictive accuracy for actual event timing remains limited. Overall, the ZINAR model proves effective for modeling complex earthquake data and provides valuable insights to support disaster mitigation efforts in the Sumatra region
Rainfall Forecasting Using Gaussian Process Regression with Brownian Motion Prior (Case Study: Special Region of Yogyakarta Province)
Full text linkClimate variability significantly impacts the agricultural sector, necessitating accurate forecasting methods to support agricultural planning. This study aims to develop a rainfall forecasting model using the Gaussian Process Regression (GPR) method with Brownian motion prior. Monthly climate data from the Yogyakarta Geophysics Station for the period January 2015 to December 2024 were utilized, comprising predictor variables (air humidity and wind speed) and response variable (rainfall). The posterior GPR model was developed for parameter estimation using the marginal log-likelihood approach, with missing data handled through seasonal mean imputation that preserves temporal patterns. The results demonstrate that the GPR model achieves reasonable forecasting performance with a Mean Absolute Percentage Error (MAPE) of 36.84% and strong correlation (r = 0.94) between predicted and actual values. The highest predicted rainfall occurred in March 2024 (20.148 mm) and the lowest in June 2024 (0.022 mm), consistent with the seasonal patterns of Indonesia\u27s tropical climate

Full text linkThe accumulation of organic waste generated by community activities poses a risk of environmental pollution if not managed properly. In addition to causing unpleasant odors, unmanaged organic waste can become a breeding ground for disease vectors and may contaminate soil and water resources. One promising solution is the use of black soldier fly (Hermetia illucens) maggot cultivation, which converts organic waste into larval biomass used as feed. This approach not only reduces waste volume but also creates economic opportunities for local communities. Black soldier fly larvae have a short life cycle and a high capacity to decompose organic waste, making them a sustainable alternative for organic waste management. This program aimed to improve the literacy and competencies of out-of-school youth in Pannyangkalang Village regarding maggot cultivation techniques as a strategy to support local economic improvement. The implementation stages included obtaining permits, conducting site surveys, delivering initial outreach, and providing technical training on cage construction, colony maintenance, larval transfer, and harvesting procedures. Beyond its waste management function, maggot production has high economic value as livestock and fish feed and may serve as an additional source of income. Program evaluation indicated positive outcomes across several indicators: participants’ understanding and practical skills increased by 85%, 75% of participants adopted maggot cultivation practices, and organic waste accumulation decreased by 80%. Although improvements in income were not yet optimal, the program delivered tangible benefits to the community and demonstrated the potential of maggot cultivation as an empowerment strategy for out-of-school youth in Pannyangkalang Village. --- Timbunan limbah organik dari aktivitas masyarakat berisiko mencemari lingkungan apabila penanganannya tidak tepat.

Preservation of Eggs Using Chitosan and Its Application in Angel Cake
Full text linkEggs are easily damaged because of their high nutritional content, particularly their protein content. Therefore, preservation methods are necessary, with one such method involving the use of chitosan to prolong the freshness of the eggs while preserving their quality. This study aimed to assess and compare the efficacy of chitosan in maintaining the quality of purebred chicken eggs when stored at room temperature and its application in processed angel cake products. The experimental approach employed for egg preservation was a completely randomized design (CRD) with four treatments (P0 = no treatment, P1 = 1% chitosan solution, P2 = 2% chitosan solution, and P3 = 3% chitosan solution), replicated five times. The data underwent variance analysis, followed by Duncan\u27s test to ascertain the impact of chitosan on egg preservation and product quality. The results revealed a significant effect (P<0.05) of chitosan solution on egg weight loss, Haugh unit, yolk index, and egg pH. Notably, 3% chitosan was more effective in maintaining egg quality than 1% and 2% chitosan coatings. In the 3% treatment, egg weight loss only experienced a shrinkage of 2.57% or 1.67 g from the initial egg weight. Haugh Unit of 65.57, yolk index of 0.41, and egg pH of 7.98. Additionally, angel cake products made from preserved eggs using chitosan exhibited significant differences (P < 0.05) compared to those made from fresh eggs. The panelists preferred the texture and organoleptic attributes of the angel cake prepared with chitosan-preserved eggs.

Management of the Plant Quarantine Release Certificate in the Loading and Unloading Process at PT. Ciomas Ariya Samudera
Full text linkThis study aims to analyze the effectiveness of Plant Quarantine Release Certificate management in supporting the smooth loading and unloading process of dry bulk at PT Ciomas Ariya Samudera. Plant Quarantine Release Certificate are quarantine requirements that must be met for the import of plant-based feed commodities, such as soybean meal (SBM), into Indonesia. The research method used a qualitative case study approach through in-depth interviews, observations, and documentation studies of administrative and operational processes. The results show that internal Plant Quarantine Release Certificate management can be said to be effective because it has been carried out systematically through document requirement planning, implementation of procedures according to SOPs, and supervision of document storage. However, its effectiveness is still hampered by several external factors such as weather, as well as technical disruptions to the online system, so it requires revision, re-coordination, or manual alternatives so that the process is not hampered. These obstacles result in delayed loading and unloading processes, increased logistics costs, and the risk of losses for animal feed company partners. Therefore, it is necessary to increase synergy between the company and relevant agencies, strengthen integrated digital systems, and conduct regular training to improve responsiveness to policy changes
