Kajian untuk menilai kerusakan maupun kerentanan rumah terhadap longsor skala detail masih jarang dilakukan. Apalagi mengenai pedoman analisisnya melalui proksi berbasis data penginderaan jauh yang masih sangat jarang dilakukan. Tujuan dari penelitian ini adalah memetakan kerentanan fisik rumah terhadap longsor menggunakan foto udara UAV (Unmanned Aerial Vehicle) serta memaparkan proses pengumpulan datanya. Hasil dari penelitian ini adalah foto udara UAV dapat digunakan untuk mengidentifikasi kerentanan fisik rumah terhadap longsor melalui interpretasi visual. Tahapan identifikasi dimulai dari observasi, lalu dilanjutkan dengan menginterpretasi proksi berupa bentuk atap dan bangunan, ukuran, material atap, lokasi dan asosiasi. Pendekatan tersebut digunakan sebagai pembantu proses interpretasi rumah dan indikator kerentanan fisik dan kunci interpretasi yang disusun secara umum memiliki akurasi diatas 80%. Hasil penilaian kerentanan fisik menunjukkan bahwa rumah di Sub DAS Bompon didominasi oleh rentan tertimbun longsor.

Limbah cair akuakultur memiliki kandungan bahan organik dan anorganik, seperti amonia dan nitrit, yang dapat menyebabkan pencemaran di badan air. Teknologi sistem resirkulasi akuakultur (RAS) dapat memberikan alternatif dengan memanfaatkan sumber daya air terbatas untuk mereduksi kontaminan organik air limbah akuakultur. Penelitian ini menggunakan kombinasi unit filter multimedia (FMM), filter karbon aktif (KA), dan nano membran (NF). Tujuan penelitian ini dirancang untuk menguji kinerja FMM, menentukan ketebalan media filter optimal, serta menentukan estimasi model isoterm adsorpsi sebagai penunjang aspek desain FMM. Enam kombinasi variasi ketebalan media zeolit (30, 60, 90 cm) dan debit aliran (22,5; 45 L/menit) digunakan untuk menguji kinerja unit. Penyisihan amonia dan nitrit berturut-turut sebesar 99,85% dan 100% lebih efektif terjadi pada ketebalan zeolit sebesar 90 cm dan debit 45 L/menit. Terkait beban biaya operasional FMM, efisiensi kedua parameter tersebut tidak diperlukan hingga mencapai optimal apabila dintegrasikan dengan unit CA dan NF. Berdasarkan analisis pemodelan isoterm adsorpsi, Model Langmuir (KL = 90,18 L/mg) untuk nitrit, serta Temkin (KT = 15,68 L/mg) dan Hasely (K= 0,45 L/mg) untuk amonia merupakan model terbaik untuk mengestimasi koefisien kapasitas adsorpsi. Nilai tersebut dapat digunakan untuk memprediksi konsentrasi nitrit dan amonia di efluen berdasarkan uji perfoma model dan analisis statistik. Aquaculture wastewater contains ammonia, nitrite, and other materials which can contribute to water pollution. Recirculation aquaculture system (RAS) technology offers an alternative approach by utilizing limited water resources to reduce organic contaminants. This research aimed to evaluate the performance of a multimedia filter (FMM), activated carbon filter (KA), and nano-membrane (NF) combination. The study focused on assessing FMM efficiency, determining the optimal filter media thickness, and selecting the appropriate adsorption isotherm model for FMM design. Six combinations of zeolite media thickness (30, 60, 90 cm) and flowrates (22.5; 45 L/min) were tested. The results showed that the highest removal efficiencies for ammonia (99.85%) and nitrite (100%) were achieved with a zeolite thickness of 90 cm and a flow rate of 45 L/min. Integrating FMM with CA and NF units can reduce operational costs without compromising efficiency. The Langmuir model (KL = 90.18 L/mg) for nitrite, and the Temkin (KT = 15.68 L/mg) and Hasely (K = 0.45 L/mg) models for ammonia were identified as the best fit models for estimating adsorption capacity coefficients. These coefficients can be used to predict nitrite and ammonia concentrations in the effluent based on performance testing and statistical analysis.

The relationship between parameters in wetlands, especially peatlands, as a part of the analysis is interesting to study. The analysis is expected to show the condition of the peatland or the state of the wetlands in general. The water table elevation (WTE) is measured daily, so to compare it with evapotranspiration and rain, daily values for these two parameters are also required. The study was conducted between June-July and August 2022 on shallow peatlands in Gambut District, Banjar Regency, South Kalimantan Province. Evapotranspiration in this study was calculated using the Hargreaves and Modified Hargreaves method which presents a daily evapotranspiration calculation. The methods only depend on the maximum and minimum temperature, the number of outer space radiation whose magnitude depends on its location on the earth's surface, and the time when the research is conducted. The results showed that the highest daily evapotranspiration value generally occurred in August, which was in accordance with previous studies, but the magnitudes were different. The daily evapotranspiration value in this study ranged from 0.5 mm to 1.8 mm, while previously, the values were greater. WTE values show a strong relationship with rainfall, where rainfall increases the WTE value, and conversely, the absence causes the WTEs to decrease gradually. In general, the condition of the peatlands in the study area based on the groundwater elevation conditions still looks quite good with a fast response to rain. The relationship of evapotranspiration with rain and water table elevation cannot be clearly seen in this study because alterations in rainfall and WTE do not directly indicate changes in evapotranspiration values, so a more extended study covering other months and more in-depth covering parameters and other methods is needed to draw valid conclusions more accurate.

This study aims to analyze the concept of Bank sampah as the rural environmental government in Indonesia. The initial reason for researching these issues is supported by the importance of collaborative governance in rural governmental organization. At this case, villagers and bank sampah is the key for this issue. The work of villagers who run the technical bank sampah necessities are need to be strengthen by local government and other stakehilders such as private, or any other non-governmental organization. Behavioural change that supposed to be existing at the beginning of bank sampah initials is broken down into several stages that also needed to be implemented by all the stakeholders. Using qualitative methods with a multiple case study approach, the researchers focused on Bank Sampah itself, community participation, and also rural environmental government in Indonesia in order to support the execution of the 3 R (reduce, reuse, and recycle) and promote behavioral change in society, Bank Sampah was founded. The government needs to establish strict regulations for stakeholder collaboration. Rural environmental governance and sustainable development are inextricably linked to village involvement as well as the rule of virtue and the rule of the people, not just from government's point of view. Also, with strong local government and environmental protection, there is hope that Indonesia's ecological civilisation will advance, particularly with the implementation of Bank Sampah.
本研究旨在分析印尼农村环境政府 Bank sampah 的概念。研究这些问题的最初原因是合作治理在农村政府组织中的重要性。在这种情况下，村民和桑帕银行是这一问题的关键。经营技术性舢板银行的村民的工作需要当地政府和其他利益相关者（如私人或任何其他非政府组织）的加强。舢板银行成立之初的行为改变分为几个阶段，也需要所有利益相关者共同实施。研究人员采用多案例研究的定性方法，重点关注桑帕银行本身、社区参与以及印尼农村环保政府，以支持 3R（减少、再利用、再循环）的实施，促进社会行为的改变，桑帕银行就是这样成立的。政府需要为利益相关者的合作制定严格的规章制度。农村环境治理和可持续发展与乡村参与、德治和民治密不可分，而不仅仅是从政府的角度出发。同时，有了强有力的地方政府和环境保护，印尼的生态文明建设就有希望向前推进，特别是随着桑帕银行的实施。

Telah dilakukan penelitian tentang sifat fisis dan kuat uji tekan batuan di karst Kawasan Gua Leang Londrong. Tujuan dari penelitian adalah untuk menganalisis besarnya nilai sifat fisis (densitas dan porositas) dan kuat uji tekan batuan. Penentuan kekerasan atau kuat tekan batuan selama ini banyak menggunakan uji kuat tekan batuan di laboratorium menggunakan Uniaxial Compressive Strength (UCS). Uji Uniaxial Compressive Strength (UCS) memiliki akurasi yang sangat baik, namun pelaksanaanya membutuhkan waktu yang lama dan memakan biaya tinggi. Oleh karena itu pada penelitian ini diusulkan metode lain untuk menentukan kuat tekan yang lebih sederhana, mudah dan murah menggunakan Schmidt Hammer. Nilai uji kuat tekan diperoleh dari metode non-destructive yaitu dengan menggunakan alat Schmidt Hammer. Proses dimulai dari pengambilan 30 sampel batuan di daearah kawasan Gua Leang Londrong pada 10 titik yang telah ditentukan. Berdasarkan hasil uji sifat fisis batuan karst di Kawasan Gua Leang Londrong, diperoleh nilai densitas batuan pada rentang 2,60 sampai 2,62 dan nilai porositas berada pada rentang 0%-7%. Sehingga jenis batuan di Kawasan Gua Leang Londrong adalah batu gamping dolomit. Nilai kuat tekan batuan diperoleh dari konversi nilai pantulan palu Schmidt menjadi nilai kuat tekan uniaksial. Diperoleh nilai kuat tekan batuan berada pada rentang nilai 20 MPa hingga 62 MPa. Sehingga batuan di Kawasan Gua Leang Londrong adalah jenis batuan yang sangat rapuh dengan karakteristik batuan lapuk sedimen terkompaksi lemah, batuan rapuh dengan karakteristik batuan tersedimentasi lemah dan batuan yang cukup keras dengan karakteristik batuan sedimen kompeten beberapa batuan beku dengan bobot isi rendah berbutir kasar.

Silo District, Jember Regency is an area with a mountainous topography dominated by relatively steep slopes. Many landslides occurred in the Silo District area. Based on the results of observations, in 2022 to July there have been 8 landslides in the Silo District area. Landslide disasters can be minimized by mapping landslide-prone areas. The mapping method used is a weighted overlay method for each parameter. The landslide parameters used in this study are: parameters of soil depth, rainfall, slope, soil type and land use. The final results of data processing for each parameter in this study will produce a map of landslide-prone areas in Silo District, Jember Regency. . Based on the research results, the landslide vulnerability classes are grouped into four classifications, namely low, medium, high and very high. The results showed that the Silo District was an area with high vulnerability (54%), medium vulnerability (37%), very high vulnerability (9%) and low vulnerability (1%). Mulyorejo Village is the village with the widest very high vulnerability classification in Silo District.

The Government of Indonesia requires oil palm plantations on peatlands to regulate the ground water table at -40 cm all year. Factors that determine the groundwater are rainfall, tidal conditions, land conversions and drainage conditions. This research aims to measure the ground water table and water balance of the oil palm plantation on the drained peats. The research was conducted from August – October 2021. The grounwater table were measured with peizoemeter installed in three blocks at an interval of 250 m, 500 m, and 750 m. The measurements were at 8 am dan 4 pm. The groundwater table ranges -4 cm to -39 cm. It seems that rainfall and tides do not have influence heights of the groundwater table in this oil palm. Further research must be done to investigate this phenomenon. A comprehensive monitoring of groundwater table covering both rainy and dry seasons is required to record the differences of groundwater tables.
