Noise is an environmental problem that needs to be addressed because it not only disturbs comfort but also causes hearing health problems. One of the ways to deal with noise is by installing sound absorbing materials. Sound absorbers commonly used are rockwool or glasswool. However, these materials are quite expensive. Therefore, various types of sound absorbing materials that are cheap and environmentally friendly, namely coconut coir and rice straw. The material made is a circle with a diameter of 100 mm and a thickness of 10 mm. The variation used is the ratio of the quantity of coconut coir and rice straw with gypsum. The variations of the coconut coir and rice straw materials used are 15 grams, 25 grams, and 35 grams. Meanwhile, 400 mL of gypsum is used. Both materials were tested to obtain the sound attenuation coefficient value. The best results obtained from the test are a mixture of coconut coir and gypsum with a sound attenuation coefficient of 0.45.

The emission of nitrogen oxide (NOx), nitrogen monoxide (NO) and carbon monoxide (CO) from vehicle exhaust gas generates an adverse effect to the environment as well as the human health. Therefore, the need to reduce such emission is urgent. The decrease of the emission can be achieved through the use of catalytic converter. This study explains the application of catalytic converter prepared from activated carbon to enhance the activity through its adsorption ability. The activated carbon was derived from banana peels after heating them up at 400 ºC for 1.5 hours and activation using natrium hydroxide (NaOH). Several techniques including N2 adsorption-desorption, X-Ray Diffraction (XRD), Scanning Electron Microscopy-Electron Dispersive X-ray (SEM-EDX), and Fourier Transform Infrared (FTIR) were adopted to characterize the activated carbon properties. The activated carbon formed was then coated with copper. The activity of the catalytic converter using activated carbon coated with copper was then tested for its performance on diesel engine Yanmar TF 70 LY-DI with variations in the number of catalyst layers, namely 1 layer (C1), 2 layers (C2) and 3 layers (C3). Sample with three layers (C3) of catalyst exhibited the highest activity with the percentage efficiency in reducing emissions concentration of 48.76 %; 31.27 % and 29.35 % for NOx, NO and CO, respectively.

Kabupaten Sampang bagian selatan merupakan daerah pesisir yang berbatasan dengan Selat Madura. Sebagian besar penduduknya bermata pencaharian sebagai nelayan dan petani tambak. Hal inilah yang membuat konsentrasi pemukiman berada di pesisir pantai. Laju perubahan penduduk membuat kawasan pesisir pantai berubah dari tahun ke tahun. Wilayah pesisir selatan ini merupakan daerah muara sungai. Daerah muara sungai pada umumnya dipengaruhi oleh gelombang air laut, pasang surut, maupun arus yang menyebabkan perubahan kondisi fisik pantai. Garis pantai merupakan salah satu komponen penting dalam penentuan batas wilayah kekuasaan suatu negara dan otonom daerah. Kawasan ini merupakan kawasan yang sangat dinamis yang terjadi secara terus-menerus. Berdasarkan kedinamisan tersebut maka diperlukan pemantauan garis pantai dengan cara membuat peta perubahan garis pantai secara berkala. Metode yang digunakan dalam analisis perubahan garis pantai adalah tumpeng susun/ overlay data citra landsat. Data yang digunakan adalah citra multi temporal meliputi citra satelit Landsat 7 dan Landsat 8 untuk perekaman satelit selama 20 tahun dari tahun 2001 sampai dengan tahun 2021, data peta RBI batas Kabupaten Sampang serta data pendukung data survey lapangan berupa koordinat beberapa titik di lokasi penelitian. Dari peta yang diperoleh di analisa adanya abrasi dan akresi selama 20 tahun. Secara keseluruhan selama 20 tahun, pesisir selatan Kabupaten Sampang mengalami penambahan panjang garis pantai dari 48.464,46 m pada tahun 2001, menjadi 52.388,97 m pada tahun 2021. Abrasi seluas 276.401,71 m2, dan akresi seluas 1.313.528,62 m2.

The low demand for vocational education graduates has led to high unemployment. The low demand for vocational education graduates has led to high unemployment. Vocational college graduates still need to be commensurate with industrial needs. Many Senior High School, Vocational High School, and Vocational College graduates have not been able to find a job for more than six months. Conditions on Madura island worsened this, and the lack of accelerated industrialization even after the Suramadu Bridge was built. Madura has the lowest Human Development Index (HDI) score in East Java. Data from the Central Bureau of Statistics (BPS) Sampang in Figures 2021) shows that the HDI value in 2020 only increased by 0.76 from 2019 of 62.70. Politeknik Negeri Madura (Poltera) together with PT. United Tractors and LSP ABI want to take an active role in improving Madura's HDI by preparing human resources on heavy equipment mechanics through the development of a centre of excellence for technology (PUT) of Heavy Equipment (CHE). Using the causal-comparative method, the researcher observed the impact of each stage on PUT-CHE development activities and reviewed the data to find causal factors and correlations. Poltera took a strategic step by equipping lecturers with virtual training on heavy equipment mechanics (SOBAT Program), organized by PT United Tractors. The SOBAT program has positively impacted heavy equipment engineering graduates in 2022, which has increased significantly. Academic data showed that 13 out of 34 heavy equipment mechanical engineering graduates were employed in leading heavy equipment industries before three months. Other data stated that three lecturers participating in Virtual Training on heavy equipment mechanics were selected as 50 interns at PT United Tractors.

Mayoritas sekolah swasta khususnya pesantren di Madura mengalami masalah dalam kualitas akademik dan administrasi. Seluruh proses administrasi yang dilakukan secara manual bisa mengurangi konsentrasi sekolah pada pengembangan kualitas akademik siswa. Salah satunya adalah perihal presensi kehadiran baik siswa, guru maupun pegawai pendidikan lainnya. Sekolah berbasis pesantren, dimana siswa yang juga santri tinggal di asrama pesantren sehingga sekolah memiliki masalah koordinasi antara sekolah dengan pesantren. Untuk meningkatkan keefektifan dan kedisiplinan dalam hal Presensi atau kehadiran terhadap siswa, guru maupun pegawai kependidikan di SMK Al Miftah Pamekasan, maka kami membuat sistem presensi fingerprint dan monitoring kehadiran berbasis web menggunakan Framework Laravel. Hal ini dilakukan agar memberikan kemudahan dalam akses perekapan data. Sehingga data tidak dikelola secara manual dan sudah terintegrasi dengan sistem presensi. Penggunaan fingerprint sebagai sistem presensi telah terbukti memberikan dampak baik bagi kedisiplinan penggunanya. Dalam kegiatan proses belajar mengajar presensi memberikan banyak informasi penting, yang didapat terkait dengan siswa. Perancangan sistem presensi-presensi berbasis fingerprint dibuat dengan metode waterfall agar dapat memberikan kemudahan bagi pihak sekolah untuk merekap data kehadiran siswa.
