The waste in the trash is still mixed, and in its management, the waste is not processed and transported immediately to TPA Jatibarang. Sustainable waste management needs to pay attention to 5 aspects of waste management, namely operational technical aspect, institutional aspect, financing aspect, legal and regulatory aspect, and community participation aspect. The purpose of this study is to obtain an integrated waste management concept from the 5 aspects of waste management. The method used in this research is descriptive qualitative, the data is taken using observation, interview, and documentation techniques. It is known that the waste generation on campus 2 is 129.36 kg / day with a volume of 1,903.98 l / day. Composition of food waste 15.74%; wood and garden waste 48,12%; plastic 9,19%; metal 0.20%; paper / cardboard 9.05%; fabrics / textiles 0.30%; glass / glass 0.41%; rubber / leather 0.42%; and other 16,56%. The operational technique of waste management is planned to use 5 separate bins based on waste types, collection using a three-wheeled open motorbike, transfer to TPST on Kampus 2, then composting the food waste and garden waste. Plastic, paper, metal, glass, and rubber can be deposited into Bank Sampah at UIN Walisongo, while cloth and other waste are disposed to TPA Jatibarang. On the regulatory aspect, there are no regulations at the university level governing waste management. In the institutional aspect, it is necessary to carry out technical training for cleaning personnel regarding solid waste management, as well as institutional strengthening. In the aspect of financing, the cost of waste management is budgeted in the Rencana Belanja dan Anggaran which is proportional to the generation of waste every year. In community participation aspect, it is necessary to conduct socialization and education to the entire academic community of UIN Walisongo to increase awareness and participation in waste management.

Climate change has the potential to alter the spatial pattern of rainfall, which is the primary variable in climate classification. The Oldeman method is one of climate classification techniques focused on agricultural management. This study's objective is to evaluate the spatial changes of the Oldeman climatic type in South Kalimantan, Indonesia assificationt of climate change. The climate in the late 21st century is simulated using data from one of the CORDEX-SEA project's products using the RCP4.5 and RCP8.5 scenarios. The shift in climate type was assesed based on the difference of the total area covered by the Oldeman climate classification during the projection period (2071-2095) and that covered during the reference period (1981-2005). The simulation data was corrected first using the linear scaling method to reduce the bias. The skill of model in reproducing Oldeman climate type was evaluated against the surface observation data from 35 sites using the percent of correct (PoC) score method. We found that the bias correction procedure successfully reduced the bias, as evidenced by a 22% rise in the correlation value of monthly rainfall and a -79% reduction in RMSE. By the end of the 21st century, both under RCP4.5 and RCP8.5 scenarios, the South Kalimantan climate is projected to be dryer, characterized by a decrease in the area covered by wet climate types (type B) and an increase in the area covered by dry and extremely dry climate types (type D and E). We discovered that the RCP8.5 scenario could result in a more tremendous shift in climate type than the RCP4.5 scenario. This study demonstrates that climate change has the potential to result in a shift in the climate classification that must be considered in agriculture policymaking.

Published: January 2023

The technique of cultivating talas bananas through tissue culture with corm explants can produce a large number of seedlings with uniform height and in a short time compared to conventional methods. However, it has a higher level of contamination, so it uses HgCl2 as the sterilant which is classified as hazardous and toxic (B3) chemical. The use of UV light exposure which is able to nonactivate contaminants can be recommended to replace the B3 material. The purposes of this study were to investigate the difference between the control and the UV light exposure time nested in sterilant types on the success of sterilization of talas banana (Musa paradisiaca L.var. Sapientum) corm explant; and to investigate the effects of sterilant types on the success of sterilization of talas banana (Musa paradisiaca L.var. Sapientum) corm explant. This study is an experimental study arranged in a Nested Completely Randomized Design with separate control repeated 3 times. The UV light exposure time  (t1 = 1.0 hours; t2 = 1.5 hours; t3 = 2.0 hours; t4 = 2.5 hours and t5 = 3.0 hours) was nested in a type of sterilant (s1 = UV light; s2 = 0.2% Fungicide + 0.2% Bactericide + 70% Alcohol + 30% Bayclin + 20% Bayclin + Betadine + UV light). The results of the study show that the sterilization of talas banana corm explants (s1 type), without using B3 HgCl2 and only using UV light, can be recommended to be applied in the propagation of talas bananas through in vitro culture.

Shrimp growth patterns will dynamically affect feeding patterns and organic waste conversion in the pond ecosystems. The purpose of this study was to determine the dynamic correlation between the amount of shrimp biomass, feed, and the solubility of organic matter in the shrimp pond ecosystem at the Salafiyah Syafi'iyah Islamic Boarding School Sukorejo, Situbondo Regency. The research method used is an ex-pose facto causal design with time series field data collection. The data taken are water quality parameter, pond water organic matter parameters, feeding data, shrimp sampling data. The results showed that the water quality parameters in aquaculture ponds were still quite good, namely pond A1 pH value 8.2, temperature 29.20C, dissolved oxygen 5.58 mg/L, salinity 25 ppt, and brightness 37 cm. For pond A2, the pH value is 8.1, the temperature is 29.20C, the dissolved oxygen is 5.52 mg/L, the salinity is 25 ppt, and the brightness is 34 cm. From the results of dynamic modeling analysis, it is found that there is a close correlation between the feeding process and the amount of waste generated in the pond with a ratio of 1: 2.86. then the process of shrimp growth rate is correlatively strongly influenced by the factor of feeding which is carried out in an aggregated manner. Based on the results of this study, it can be concluded that according to the interpretation of the results of the analysis of the dynamic modeling system, there is a positive correlation between the increase in the amount of shrimp biomass with the quantity of feed and the abundance of organic matter in the pond which is estimated to take place in an aggregate manner.

Dalam rangka mewujudkan Sustainable Development Goals (SDGs), Kementerian Desa, Pembangunan Daerah Tertinggal dan Transmigrasi RI (Kemendes PDTT) menurunkan SDGs Nasional menjadi SDGs Desa. SDGs Desa adalah pembangunan total atas desa. Seluruh aspek pembangunan harus dirasakan manfaatnya oleh warga desa tanpa ada yang terlewat yang mengarah pada 18 tujuan pembangunan berkelanjutan. Untuk mewujudkan SDGs Desa, Kemendes PDTT telah menerbitkan Peraturan Menteri Desa PDTT No 13/2020, yang menyatakan Rp 72 triliun dana desa tahun 2021 diarahkan untuk mencapai tujuan-tujuan SDGs Desa. Pembangunan berkelanjutan merupakan konsep pembangunan dengan mempertimbangkan berbagai aspek sehingga tidak mengganggu kondisi alam dan tetap dapat memenuhi kebutuhan selanjutnya. Agar tujuan ini dapat direncanakan dan dilaksanakan dengan baik, perlu kajian dan inventarisasi awal terhadap potensi yang dimiliki oleh suatu desa, dan hal ini dapat dilakukan dengan menyajikannya dalam bentuk peta dasar berbantuan aplikasi Sistem Informasi Geografis. Metode yang digunakan untuk pembuatan peta dasar dalam rangka menginventarisasi potensi desa adalah dengan dilakukan dengan survei lapangan dan foto udara dengan bantuan pesawat tak berawak (drone). Hasil studi ini menunjukkan kondisi riil dan peta foto udara desa yang menjadi target kegiatan. Keberadaan peta peta dasar ini selanjutnya dapat dimanfaatkan dalam inventarisasi potensi desa, perencanaan dan pelaksanaan program SDGs, serta monitoring pelaksanaan dan evaluasi program pembangunan desa.

Adanya aktivitas penambangan akan meninggalkan lubang bekas tambang yang menimbulkan perubahan lingkungan sehingga akan menjadi danau buatan, keadaan mempengaruhi kualitas air pada daerah tersebut terutama nilai pH dan karakteristik geokimia air. Kualitas air pada area bekas tambang akan mempengaruhi kondisi kualitas air tanah di sekitar danau bekas tambang. Tujuan penelitian ini untuk mengetahui arah aliran air tanah, kualitas air dan mengetahui bentuk tipe danau bekas tambang aluvial. Metode yang digunakan dalam penelitian ini adalah metode penelitian lapangan dan pengujian di laboratorium. Permodelan arah air tanah dan model limnologi menggunakan aplikasi Software. Parameter yang di ukur di lapangan adalah koordinat easting dan norting suhu, kedalaman dan DO. Sedangkan kualitas yang di ukur di laboratorium adalah pH, TDS, TSS, ORP, EC HCO3, CO2, CaCO3 dan H+. Arah aliran air tanah masuk di danau bekas tambang aluvial akan mempengaruhi kondisi air danau bekas tambang aluvial. Namun, kondisi danau terlihat sudah tunak (steady-state) dimana air danau hanya dipengaruhi oleh presipitasi dan evaporasi lingkungan di danau tersebut. Keadaan ini mempengaruhi nilai pH air danau, sungai dan sumur yang disekitar danau. Danau bekas tambang aluvial memiliki nilai pH asam 3,81. Danau ini bersifat monomictic, karena mengalami penurunan suhu, DO dan nilai pH pada setiap kedalaman.

Pada perusahaan PT Senamas Energindo Mineral memiliki wilayah izin penambangan seluas 2000 Ha. Setelah dilakukannya pemboran eksplorasi ditemukan adanya endapan batubara yang cukup potensial untuk ditambang. Dengan penemuan cadangan baru ini perlu dilakukan perencanaan untuk membuat pit, pit tersebut diberi nama Pit 1. Sehingga perlu dilanjutkan dengan tahapan penambangannya dan belum ada yang membuat penjadwalan penambangannya. Berdasarkan hal tersebut, melatarbelakangi saya melakukan pengamatan dan penelitian ini. Penjadwalan penambangan dibuat dengan menggunakan software Minescape.  Batas penambangan, cadangan   tertambang, dan volume overburden ditentukan oleh nilai Stripping Ratio (SR) dari perusaahaan yaitu SR  6. Penjadwalan dilakukan dengan cara membagi daerah pit limit penambangan menjadi block-block dengan ukuran 75 x 75 meter. Pembagian block tersebut bertujuan untuk mempermudah sequence atau pushback pengupasan overburden dan sequence produksi batubara. Perhitungan volume menggunakan software Minescape. Tahapan penambangan dibuat dengan target produksi minimum 100.000 ton/bulan. Hasil penelitian dari penjadwalan penambangan pit 1 block 24 didapatkan penjadwalan penambangan yaitu dengan kurun waktu 43 bulan yang mana memiliki SR terendah 1.72 pada bulan September 2017 dan SR tertinggi 36.65 pada bulan April 2021.

Dalam kegiatan penambangan harus menggunakan metode dan peralatan mekanis yang sesuai dalam kegiatan tersebut. Salah satu penentu keberhasilan metode penambangan adalah seberapa besar produktivitas peralatan mekanis dapat dimanfaatkan seefektif dan seefisien mungkin agar diperoleh hasil yang maksimal. Penggunaan fuel sangat mempengaruhi biaya produksi dari aktifitas penambangan, semakin banyak fuel yang digunakan maka semakin besar pula biaya produksinya. Untuk meminimalisir penggunaan bahan bakar maka harus mengetahui hal-hal yang mempengaruhinya agar penggunaan fuel dapat diminimalisir oleh perusahaan. Metode yang digunakan adalah dengan mensimulasikan hasil produktivitas dengan fuel burn jika delay time dihilangkan dari pengolahan data yang didapatkan dilapangan. Setelah melakukan simulasi hasil pencapaian fuel burn untuk alat gali muat Komatsu PC300 yaitu 36,86 Liter/Jam dengan produktivitas rata-rata sebesar 145,00 bcm/jam. Fuel burn rata-rata untuk alat angkut Nissan CWB45 yaitu 10,27 Liter/Jam dengan produktivitas rata-rata sebesar 21,84 bcm/jam. Fuel ratio aktual untuk alat gali muat Komatsu PC300 yaitu 0,25 Liter/bcm.  Sedangkan untuk alat angkut Nissan CWB45 yaitu 0,47 liter/bcm. Fuel ratio alat gali muat turun menjadi 0,22-0,28 liter/bcm dan fuel ratio alat angkut turun menjadi 0,41-0,48 liter/bcm, jika di simulasikan komponen delay tidak ada atau efisiensi kerja 100%.

Energi sumberdaya alam menjadi suatu kebutuhan penting untuk menunjang kegiatan perindustrian terutama penambangan batubara dengan kualitas yang memadai. Suatu perusahaan tambang batubara memiliki kebutuhan dengan kriteria kualitas batubara yang berbeda-beda. Pengendalian kuantitas dan kualitas batubara sesuai permintaan menjadi acuan bagi perusahaan penambangan. Pengendalian mutu batubara merupakan kendala dalam penambangan batubara, diantaranya kemunculan silicified coal sebagai pengotor (impurities) pada lapisan batubara yang akan ditambang, yang apabila keterdapatannya berfragmen melensa maka dapat berdampak pada sulitnya proses penggalian.Komposisi mineral utama dari silicified coal adalah mineral silika yang memiliki keterdapatan pada rekahan dan rongga sel tumbuhan. Silicified coal memiliki kekerasan 15.000 Kpa - 50.000 Kpa dengan kandungan silika dan karbonan yang melimpah. Kandungan organik berupa densinite, ulminite, attrinite, corpohumnite, gelinite, suberinite, resinite, liptodetrinite, fusinite, dan funginite dan kandungan non organik berupa mineral kuarsa, klorit, lempung, rutil, dan opak/oksida besi, aragonite, calcite, gismondine dan graphite.
