This article analyzed the learning experience of students at home during the school closing period in response to the Covid-19 pandemic in Indonesia. Through this study, an in-depth understanding of the life experiences, perceptions, and motivation of students were obtained from either the school or their parents. These outputs would be input into policy making and solving learning problems towards a new normal era. Now the school closures have been running for almost seven months and it almost about to reopening this mid-August 2020. To understand this phenomenon issue, some data searching have been performed ranging from daily papers, academic journal, and educational related literature. The data search then analyzed under the phenomenological application approach. Compiling the existing data and students voices, this study showed that the students learning experiences during six month learning from home responding the national policy stopping the corona virus spreading can be reported based on 10 websites visited have expressed their best coverage over students learning difficulty and challenge from different perspectives. Most websites mentioned students hardship in learning from home caused the lack of learning resources such not access to internet and parents ability to support their children learning.

ABSTRAKSungai Kupang adalah salah satu sungai yang mengalir di Kota Pekalongan yang menerima limbah, baik dari industri, pertanian maupun domestik, Perkembangan industri dan pemukiman di sepanjang aliran sungai Kupang telah mempengaruhi kualitas air sungai. Penurunan kualitas air ditandai dengan perubahan warna air dan bau padahal sebahagian masyarakat di pinggiran sungai masih memanfaatkan air Sungai Kupang untuk kebutuhan sehari-hari. Penelitian ini bertujuan untuk menganalisis kualitas air sungai Kupang berdasarkan baku mutu kualitas air sungai menurut PP Nomor 82 Tahun 2001, menghitung beban pencemar Sungai Kupang dan menentukan Status Mutu Air serta merekomendasi upaya pengelolaan kualitas air Sungai Kupang Pekalongan. Pengukuran kualitas air dilakukan pada 6 titik pengambilan sampel. Parameter yang diukur dan diamati adalah parameter Temperatur, TSS, pH, DO, BOD, COD, Kromium dan Phosphat. Untuk analisis Status mutu air Sungai Kupang dengan menggunakan metode indeks pencemaran dan daya tampung beban pencemaran dengan menggunakan metode Qual2Kw. Hasil penelitian pada kualitas air Sungai Kupang menunjukkan parameter COD di beberapa titik telah melebihi baku mutu. Sedangkan untuk parameter BOD di semua titik telah melebihi baku mutu yang dipersyaratkan. Nilai konsentrasi BOD terendah adalah sebesar 5,75 mg/l, sedangkan nilai BOD tertinggi sebesar 27 mg/l. Kandungan BOD meningkat diduga karena sepanjang aliran sungai yang di mulai dari hulu hingga hilir banyak menerima limbah buangan, sementara berdasarkan status mutu air menunjukkan penurunan kualitas air dari hulu sampai ke hilir sungai, dimana pada bagian hilir telah tercemar ringan. Dan untuk hasil perhitungan beban pencemaran Sungai Kupang dari hulu ke hilir mengalami peningkatan, untuk beban pencemaran konsentrasi TSS adalah sebesar 20.670,334 kg/hari, sedangkan konsentrasi COD adalah sebesar 16.517,777 kg/hari, dan konsentrasi BOD yaitu sebesar 6.618,643 kg/hari. Kata kunci: Water Quality, Pollution Load, Kupang River ABSTRACTSungai Kupang is one of the rivers that flow in Pekalongan city that receives the waste, both from industrial, agricultural and domestic, industrial and residential development along the river Kupang have affected the quality of river water. Water quality degradation characterized by changes in water color and odor when sebahagian riverside communities still use river water Kupang for everyday needs. This study aimed to analyze the water quality of the river Kupang based on river water quality standards in accordance with Regulation No. 82 of 2001, calculating the pollutant load Sungai Kupang and determine Air Quality Status and recommend management measures Pekalongan Kupang River water quality. Water quality measurements performed at 6 sampling points. Parameters measured and observed are the parameters of temperature, TSS, pH, DO, BOD, COD, chromium and Phosphate. For the analysis of the water quality of Sungai Kupang status using the pollution index and pollution load capacity using Qual2Kw. The results of research on water qua...

Abstrak--Peningkatan Kata kunci: RDF (Refused Derived Fuel), material sampah combustible, bom kalorimeter, Nilai Kalor Tinggi Abstract--The increase of waste dump also causes the need of landfill in Jatibarang Landfil. In order to avoid land deficiency, the waste dump needs to be handled by converting waste into energy sources such as RDF (Refused Derived Fuel

Inundation of flood and rob (flood due to high tides) in Semarang City is increase wtithin area and depth. It be more seroius condition because of land subsisdence that happened in coastal area of Semarang City. This research is foccused on prediction and mapping of inundation flood and rob due to land subsidence effect in East Semarang, especially Tenggang Watershed and Sringin Watershed. On this research, data analysis including analysis of land subsidence, analysis of hydrological data, analysis of flood discharge with HEC-HMS, hydraulics analysis with HEC-RAS and then mapping the results of the flood inundation with Arc GIS. The inundation will be create with overlay the DEM of flood water level and DEM of topographic. According to the results of analysis is known that minimum land subsidence is 0 cm/year that happened in south area of Semarang and more higher ini north area with maximum land subsidence is 5.58 cm/year. On periode   2014-2031, the contribute of land subsidence to increase the inundation of flood and rob is 1.39%/year.

The purpose of this study is to contribute to the ability to read Al-Qur'an for MI children on the subject of the Al-Qur'an Hadith because reading the Al-Qur'an becomes the flagship program at MI Muhammadiyah Ketapang.

Effective solid waste management strategies are recognized as efforts to achieve campus sustainability. The university campus is currently considered the center of various activities involving students, lecturers, staff, and other parties contributing to the consumption pattern of energy, water, and other resources. This study aims to estimate the quantity and compositions of waste generated on the Universitas Diponegoro (UNDIP) campus, identify the causes of waste generation, evaluate the relationships between variables through statistical analysis, and recommend possible strategies to reduce solid waste generation. The results show that the simultaneous contribution of the student-gender ratio, student awareness level, administrative staff background, and green space amounted to 67.7% of the waste generation at UNDIP. Therefore, these four factors need to be a concern for campus authorities in their efforts to handle campus waste. Student awareness in particular was determined to be the only factor that significantly affects solid waste generation. UNDIP may implement proper environmental education through sustainability courses in each faculty to reduce solid waste in higher education institutions since it has the most significant impact. Outcomes of this study could be used as a reference to develop sustainable campus strategies, recycling plans, and comprehensive waste management in higher education.

This study aimed to examine the performance of fly ash mixed materials with bentonite binder (FAB) as a recent low-cost containment system to withstand leachate infiltration. The mixture of fly ash with clay (bentonite) can increase the strength of stability and strengthen cohesion bonds between molecules. Direct shear, falling head, Atterberg limit and specific gravity test have been conducted as a preliminary study to determine the precise mixture composition of fly ash-bentonite (FAB) landfill liners. Some bentonite composition: 0% (FAB 0 ), 15% (FAB 15 ), 20% (FAB 20 ), 25% (FAB 25 ) and 25% -cured with NH 4 Cl (FAB 25s ) for 24 hours, which mixed with fly ash, showed the value of shear stability at normal stress reaching 9.5 kNm -2 , 15.48 kNm -2 , 45.06 kNm -2 , 46.26 kNm -2 and 13.67 kNm -2 , respectively. It showed that the greater the content of bentonite in the mixture, the higher the shear stress produced. Curing with saline solution can reduce the shear stress of the FAB mixture. The safety test results using Geoslope/W ® show that the addition of bentonite will increase bonding between particles, bearing capacity, and shear strength of the material. The largest safety factor of 1.674 obtained from FAB20 material meets the safety standard for short-term slope stability. The use of fly ash material with bentonite is expected to be an alternative landfill liner material.
