Abstract

The aim of this research was to screen several long bean accessions against salinity stress. Soil salinity has a negative effect on plant growth and productivity. Information on the response of long bean accessions is very necessary as a basis for breeding long beans that are adaptive to saline land. This research was conducted from September to December 2019 on the grounds of the Agrotechnology Innovation Center, Gadjah Mada University. The research was carried out using the Factorial Randomized Block Design experimental method with 2 factors and 3 replications. The research results show that the FB-KP 167 and FB –KP 144 accessions can be considered as plants that are resistant to salinity because their growth and productivity are higher than other accessions. The results of the Analysis of Variance (ANOVA) test showed that there was no significant difference in salinity treatment on plant height and flowering age, but there were significant differences in pod length and number of seeds per pod. Keywords: Long Beans, Resistance, Salinity Stress, Screening INTISARITujuan penelitian ini adalah untuk men-skrinning beberapa aksesi kacang panjang terhadap cekaman salinitas. Salinitas tanah berpengaruh buruk terhadap pertumbuhan dan produktivitas tanaman. Informasi respon aksesi kacang panjang sangat diperlukan sebagai dasar pemuliaan kacang panjang yang adaptif terhadap lahan salin. Penelitian ini dilakukan pada bulan September sampai dengan Desember 2019 di lahan Pusat Inovasi Agroeknologi Universitas Gadjah Mada. Penelitian dilaksanakan dengan menggunakan metode percobaan Rancangan Acak Kelompok Faktorial dengan 2 faktor dan 3 kali ulangan. Hasil penelitian menunjukkan aksesi FB-KP 167 dan FB –KP 144 dapat dipertimbangkan sebagai tanaman yang tahan terhadap salinitas karena pertumbuhan dan produktivitasnya yang lebih tinggi dibanding aksesi lainnya. Hasil uji Analysis of Variance (ANOVA) menunjukkan tidak ada beda nyata perlakuan salinitas terhadap tinggi tanaman dan umur berbunga namun terdapat beda nyata pada panjang polong dan jumlah biji perpolong. Kata Kunci : Kacang Panjang, Ketahanan, Cekaman Salinitas, Skrinning

Abstract

Sosialisasi ini bertujuan untuk mengedukasi para siswa SD Negeri 101640 Portibi mengenai dampak dari perundungan. Perundungan merupakan masalah serius di lingkungan sekolah dasar, yang dapat memiliki dampak jangka panjang terhadap kesejahteraan psikososial anak-anak. Untuk mengatasi masalah ini, program sosialisasi merupakan strategi penting dalam meningkatkan kesadaran dan mempromosikan sikap positif terhadap perbedaan di antara siswa. Kegiatan sosialisasi ini merupakan salah satu bentuk pengabdian kepada masyarakat yang dilakukan oleh Kelompok 6 Kuliah Kerja Nyata Tematik (KKNT) ITS Paluta di SD 101640 Portibi. Kegiatan ini melibatkan partisipasi aktif siswa-siswi SD sebagai sasaran utama sosialisasi. kegiatan ini menggunakan metode ceramah dan observasi. hasil dari kegiatan sosialisasi ini menunjukkan adanya peningkatan yang signifikan terhadap pemahaman siswa-siswi mengenai bullying, serta perubahan sikap positif terhadap sesama

Abstract

The low productivity of long beans in Sipahoras Lama Village, caused by conventional cultivation systems lacking soil protection, poses a significant challenge to local food security. This Student Creativity Program (PKM) aims to introduce Silver-Black Plastic Mulch technology to address weed competition and microclimate fluctuations. The implementation method employed a participatory approach, encompassing problem identification, socialization, and technical training through the establishment of demonstration plots. The results indicated a significant improvement in the partners' skills in applying the technology independently. Agronomically, the use of mulch proved effective in suppressing weed growth, maintaining soil moisture stability, and producing healthier vegetative plant performance compared to control plots. It is concluded that this transfer of appropriate technology serves as an effective strategy to enhance farming efficiency and support sustainable village food self-sufficiency.

Abstract

The transformation of tropical landscapes due to agricultural expansion constitutes a significant global environmental challenge. Current land-cover classification methods, however, provide limited differentiation among agricultural management systems. This study develops an agriculture-focused land-cover classification workflow that fuses Landsat 9 optical imagery and PALSAR-2 L-band SAR across a ≈2,500 km² study area in Jambi Province, Sumatra, Indonesia, to enhance discrimination of crop systems and improve spatial coherence via object-based enhancement. A 22-class land-cover taxonomy was supported by 14,029 strategically collected training points. Feature engineering produced 29 predictor variables, including conventional vegetation indices, agricultural-specific metrics, water indicators, and SAR-derived structural features. Models were evaluated on an independent test dataset comprising 4,209 samples. An agriculture-weighted Random Forest classifier with strategic class weighting was implemented and followed by Simple Linear Iterative Clustering (SLIC) object-based enhancement to suppress speckle and enforce spatial contiguity. The classification achieved an overall accuracy of 53.7%, with exceptional performance for estate crop systems (F1 = 94%) and reliable forest discrimination. SLIC reduced salt-and-pepper noise by 99.5% and substantially improved spatial coherence metrics, transforming fragmented pixel-based outputs into operationally viable products. Despite these gains, discriminating smallholder mosaics remains challenging and likely requires additional temporal or higher-resolution inputs.
