Abstract

Bank BRI is a government-owned company with share prices recorded in the Initial Public Offering (IPO) which has the status of a public company. BRI Bank's share price experienced fluctuations caused by some factors. Predicting BRI Bank share prices is important to make it easier for investors to enter make investment decisions. Auto Machine Learning (AutoML) refers to the concept of machine learning and training automatic parameter setting. H2OAutoML can be used to predict stock prices with deliver program code and accelerate the development of accurate algorithms. H2OAutoML provides various algorithms, but the one used in this research is the Generalized Linear Model (GLM), Distributed Random Forest (DRF), Gradient Boosting Machine (GBM), and stacked ensemble. The aim of this research is to find out the optimal algorithm and prediction results produced by H2OAutoML on close stock prices. Algorithm The best basis according to H2OAutoML is GBM with the smallest MAPE value and the largest R Square. However, when this basic algorithm combined with stacking techniques produces better predictions. The basic algorithm used to build stacked ensembles are DRF, XRT, GLM, and GBM. This stacked ensemble is constructed sequentially automatically by H2OAutoML with the GLM metalearning algorithm. Thus, stacked ensembles are capable predicts with fairly good accuracy and can explain data variability.

Artikel ini bertujuan untuk mendeskripsikan pelaksanaan dan hasil program pemberdayaan ekonomi melalui usaha ternak ayam kampung petelur bagi perempuan kepala keluarga di Kabupaten Karanganyar sebagai upaya peningkatan kemandirian ekonomi keluarga yatim. Metode yang digunakan adalah pendekatan pemberdayaan partisipatif yang dilaksanakan melalui empat tahapan, yaitu persiapan dan seleksi peserta, pelatihan serta pendampingan teknis, implementasi usaha dan monitoring, serta evaluasi keberlanjutan program. Data dikumpulkan melalui observasi, wawancara, dan pencatatan produksi usaha peserta selama program berlangsung. Hasil kegiatan menunjukkan bahwa program ini berhasil meningkatkan pengetahuan dan keterampilan peserta dalam manajemen pemeliharaan ayam kampung petelur, pemasaran, dan pencatatan keuangan usaha. Berdasarkan evaluasi kinerja usaha, pada bulan keempat produksi telur peserta mencapai rata-rata 12–15 butir per hari, sehingga mampu memberikan tambahan pendapatan antara Rp 250.000,- hingga Rp 400.000,- per bulan. Selain dampak ekonomi, program ini juga menimbulkan perubahan sosial positif berupa peningkatan kepercayaan diri, kemandirian, serta tumbuhnya semangat kewirausahaan pada keluarga penerima manfaat.

Abstract

Background: Female heads of households in rural areas face economic vulnerability due to limited access to productive resources and high dependence on household food expenditures. In rural households, the potential of kitchen waste and yard land has not been managed in an integrated manner. Purpose of the Study: This article aims to analyze the implementation of a community service program based on a circular economy through the integration of native chicken (layer) farming, kitchen waste management, and micro-vegetable gardens for female heads of households. Methods: The community service program used a Participatory Action Research (PAR) approach, involving participants as active subjects in problem identification, action planning, implementation, and reflection. Data was collected through participatory observation, FGDs, interviews, questionnaires, and production records. Results: The results showed a Hen Day Production rate of 70–80%, additional income of Rp 180,000–Rp 390,000 per month, and savings on vegetable purchases of Rp 40,000–Rp 60,000 per month. The integration of activities formed a circular economy flow that strengthened household economic and food resilience.
