“…The clustering pattern can be enriched from the data through clustering analysis using machine learning based on unsupervised. Agricultural data such as rainfall [23], irrigation [24], and yield [25] have been successfully mapped based on AI data patterns. In order to fully enrich our research findings in the future, the use of AI and the inclusion of data measurement parameters can be employed.…”

Due to the depletion of its natural population, the Gyrinops versteegii species, one of the species producing agarwood, has been domesticated in Indonesia, particularly in Sragen Central Java. As a result, it was designated as a vulnerable species in both CITES Appendix II and the IUCN Red List Ver23. The research objective is to determine the effect of the light intensity on the number of seedlings, tree density, height, and diameter of the G.versteegii tree growth. The study was conducted from February to October 2018 at a domesticated agarwood community forest in Sragen, Central Java. A systematic plot method, a random start, was applied to this research with 28 nested plots, 1x1 m2 for seedlings and 10x10 m2 for the trees. The data were analyzed using both hierarchical clustering and correlation analysis. The relative light intensity of 2,82% led to an enormous number of seedlings and tree diameter, while the relative light intensity of 0.31% resulted in the highest tree density. The number of seedlings and tree diameter was strongly correlated with the relative light intensity. In contrast, there is an inverse relationship between tree density and relative light intensity.

The food crisis caused by the Covid-19 pandemic has caused the level of hunger to increase to a chronic level that is almost experienced by the whole world, including Indonesia. The increase in population with extreme climate change is a serious problem to overcome the food crisis in the next few years. The impact of climate change with changes in land use results in limited water availability in the development of irrigated land. One solution to overcome the availability of water for the development of irrigated land is to rehabilitate and improve the network of swamp irrigation areas that utilize the dynamics of tidal water levels. Pantai Swamp Irrigation Area is one of the potential lands to be developed into agricultural cultivation land. The study aims to determine the effect of tidal water level elevation on irrigated land based on hydro-topography. The study was conducted in the Pantai Swamp Irrigation Area with the water source coming from the tidal Kapuas Murung River. The method was conducted quantitatively using HEC-RAS software based on tidal data, cross-section and length of the channel, and surface elevation of irrigated land. The results showed that the influence of the tidal dynamics of the Kapuas Murung River is very dominant in irrigating the land with an average tidal water level elevation of + 1.57 m with hydro-topographic dominance included in categories B and C with an area of B 604.5 Ha and C 1201. 5 Ha.Keywords: Tides, Swamps, Hydro-topography, Sungai, Kapuas ABSTRAKKrisis pangan yang diakibatkan oleh pandemic Covid-19 mengakibatkan tingkat angka kelaparan meningkat hingga mencapai angka kronis yang hampir dialami oleh seluruh dunia termasuk Indonesia. Pertambahan jumlah penduduk dengan perubahan iklim yang sangat ekstrem menjadi permasalahan yang cukup serius untuk mengatasi krisis pangan dalam beberapa tahun kedepan. Dampak perubahan iklim dengan perubahan tata guna lahan mengakibatkan jumlah ketersediaan air terbatas dalam pengembangan lahan irigasi. Salah satu solusi untuk mengatasi ketersediaan air untuk pengembangan lahan irigasi yaitu dengan rehabilitasi dan peningkatan jaringan daerah irigasi rawa yang memanfaatkan dinamika muka air pasang surut. Daerah Irigasi Rawa Pantai menjadi salah satu lahan yang berpotensi untuk dikembangkan menjadi lahan budidaya pertanian. Penelitian bertujuan untuk mengetahui pengaruh elevasi muka air pasang surut terhadap lahan irigasi yang ditinjau berdasarkan hidro-topografi. Kajian dilakukan di Daerah Irigasi Rawa Pantai dengan sumber air berasal dari pasang surut Sungai Kapuas Murung. Metode dilakukan secara kuantitatif menggunakan Software HEC-RAS berdasarkan data pasang surut, tampang melintang dan memanjang saluran, dan elevasi permukaan lahan irigasi. Hasil penelitian menunjukan pengaruh dinamika pasang surut Sungai Kapuas Murung sangat dominan dalam mengairi lahan dengan elevasi muka air rata-rata pasang berada di ketinggian + 1.57 m dengan dominasi hidro-topografi termasuk dalam kategori B dan C dengan luasan B 604.5 Ha dan C 1201. 5 Ha.

“…The main primary channel is part of an irrigation network system with a length of 28 km consisting of 11 secondary buildings from upstream (L) to downstream (V), which have decreased capacity due to sedimentation at the bottom of the channel, and embankments overgrown with weeds are shown in Figures 6 and 7. The influence of the Kapuas Murung River tide from downstream (V) and the Barito River in the upstream (L) can result in backflow due to sedimentation resulting in open water and lowering the pH level in the primary channel [12].…”

This study aims to understand the flow and water quality behaviour in response to the combination of rainfall and tides in the Dadahup Irrigation Area. Rainfall and tides have a strong influence on the Dadahup Irrigation Area. The impact of floods and droughts which hit the area in recent years changed its water quality because of salinity intrusion and the presence of pyrite in the irrigation area. The existing gates and levees along the main primary channel cannot fully regulate the water level on the other channels and on the paddy fields. This condition has resulted in crop failure in several places. Parameters of flow and water quality data such as rainfall, water level, pH, and salinity were measured from an newly installed telemetric monitoring system. A sampling period was selected in which both rainy and dry conditions were present. In that period, tides also oscillated the water level. Hydraulic simulations will analyze the hydrodynamic condition along with the observation results and will describe the flow profile and water quality changes. Simulations show that a high-intensity rainfall can immediately raise water levels in the main primary channel, and it impacts increasing pH and decreasing salinity.
