Abstract

The main problem in Kedai Gunung Balau Bandar Lampung is about waste management that is less than optimal, because the waste produced is just piled up and burned immediately. To anticipate waste problems that will cause pollution to the environment, it is necessary to make waste management efforts. Therefore, to plan a waste management system in the Kedai Gunung Balau Bandar Lampung Tourism Area, it is necessary to study the waste generation and composition at that location. The method used is waste sampling carried out for 8 consecutive days which refers to SNI 19-3964-1994. The results obtained are the average weight of waste generation per day of 25.620 kg / day and the average volume of waste generation per day of 0.945 m3 / day. The composition of waste generated consists of 11 types of waste in the form of organic and inorganic waste. The largest waste composition is food waste with a percentage of 19.528%.

Abstract

Along with population growth in Indonesia which continues to increase, natural resources (SDA) experience a decrease in availability (energy crisis). Steps that can be taken to overcome e the energy crisis is to optimize the use of biomass energy as an alternative fuel. One of them is to take advantage of palm fronds and shell waste produced by PT. Perkebunan Nusantara VII Unit Bekri as charcoal briquettes. The process of making briquettes includes drying, carbonization, grinding, screening, and printing. The composition of the briquette raw material mixture consists of five variations, namely V1, V2, V3, V4, and V5. The purpose of this study was to analyze the quality of the briquettes based on testing the proximate value (moisture content, volatile matter content, ash content, and bound carbon content), calorific value, and the burning rate briquettes. The best results for the quality of briquettes from the use of waste palm fronds and shells were obtained in the V5 variation (50% fronds, 40% shells, and 1% adhesive), with a moisture content of 3,65% (SNI 8), volatile matter content of 25,30% (SNI 15), ash content of 6,68% (SNI 8), bound carbon content of 68,03%, calorific value of 6.281 (SNI 5.000), and burning rate of 0,00117 gr/s.

Abstract

Chrome (Cr) is one of the harmful heavy metals whose existence could lead to a decline in water quality, as well as harm the environment and aquatic organisms. One of the industries that generate the waste water containing chrome is the batik industry. The resulting wastewater processing needs to be done, one of which is to combine the adsorbents and trembesi seeds fitoremediasi plants Salvinia (Salvinia molesta). The purpose of this research is to know the levels of chrome on the process of adsorbsi and fitoremediasi process. This research was conducted with two processes, i.e. processes adsorbsi and fitoremediasi process. On the process of adsorbsi use two variations of the size that is the size of the mesh 30/40 mesh 60/70 and, after passing through the adsorbsi process then continues to process fitoremediasi. Treatment on the process of fitoremediasi that is the difference between living plants, IE 0-day, 2-day and 4-day. Sampling is done on each process, which is then carried out in the laboratory of environmental engineering laboratory. Based on the results of the research that has been done, the combination of adsorbent and trembesi seeds fitoremediasi plants Salvinia (Salvinia molesta) is capable of lowering the levels of chromium in waste batik. On the process of adsorbsi with 30/40 mesh size variation is obtained as a result of 8.771 mg/L and 60/70 mesh size variation of 8.092 mg/L is obtained from figure control 10.563 mg/l. To process fitoremediasi with the variation of size of mesh 30/40 adsorbent on day 0 8.730 mg/L, at 6.962 day 2 mg/L, on the 4th day of 6.212 mg/l. fitoremediasi Process with variation of the size of the mesh 60/70 adsorbent, on the 4th day 0 6.843 mg/L, on the 2nd day 5.752 mg/L, on the 4th day of 5.688 mg/L.

Abstract

Cone Penetration Test (CPT), atau yang dikenal sebagai sondir, merupakan metode penyelidikan geoteknik yang sering digunakan untuk menentukan profil tanah dan kedalaman lapisan tanah keras. Robertson mengembangkan metode klasifikasi tanah yang berbasis pada data CPT, yang memungkinkan interpretasi stratigrafi tanah serta estimasi sifat-sifat mekanis tanah, seperti kekuatan geser dan konsolidasi. Selain efisien dari segi biaya, CPT juga memberikan keuntungan dalam hal kecepatan pelaksanaan di lapangan dibandingkan metode uji tanah lainnya. Penelitian ini menyajikan metode untuk mengklasifikasikan jenis perilaku tanah (Soil Behavior Type/SBT) berdasarkan data CPT menggunakan pendekatan dari Robertson. Hasil analisis ini tidak hanya membantu mengidentifikasi jenis tanah seperti lempung, lanau, pasir, dan kerikil, tetapi juga memberikan wawasan penting dalam desain fondasi, penentuan kapasitas dukung tanah, dan penanganan risiko geoteknik lainnya, seperti potensi likuifaksi dan stabilitas lereng. Pada penelitian ini dilakukan 4 titik pengujian untuk menentukan stratigrafi tanah yang ada di sekitar Masjid At Tanwir ITERA, Lampung Selatan. Dengan menggunakan SBT dari Robertson, didapatkan hasil kira – kira dari kedalaman 0 – 3 m dari permukaan tanah merupakan formasi tanah berbutir halus dan 3 - 6.8 m diisi oleh tanah berbutir kasar. Untuk konsistensi tanah yang didapatkan merupakan jenis tanah Stiff di permukaan dan Medium Dense – Dense untuk lapisan sampai kedalaman tanah keras.

Abstract

Sekolah Dasar Negeri 02 Way Huwi di Kabupaten Lampung Selatan menghadapi berbagai tantangan dalam penerapan Perilaku Hidup Bersih dan Sehat (PHBS), mulai dari keterbatasan sarana cuci tangan, rendahnya kebiasaan mencuci tangan pakai sabun, konsumsi jajanan yang tidak memenuhi standar higienitas, hingga rendahnya kesadaran pemilahan sampah. Kondisi ini menimbulkan risiko kesehatan yang serius, khususnya meningkatnya potensi penyakit berbasis lingkungan dan makanan pada siswa. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pemahaman sekaligus membentuk kebiasaan hidup sehat pada siswa melalui pendekatan edukasi yang interaktif, praktis, dan menyenangkan. Metode pelaksanaan meliputi persiapan, penyuluhan dalam bentuk ceramah interaktif, pemutaran video edukasi, demonstrasi enam langkah cuci tangan menurut standar WHO, simulasi pemilahan sampah organik dan anorganik, kuis berhadiah, serta penyediaan media visual berupa poster edukatif. Evaluasi dilakukan melalui pre-test dan post-test dengan instrumen bergambar untuk menyesuaikan dengan tingkat pemahaman siswa sekolah dasar. Sebanyak 26 siswa dari kelas IV dan V berpartisipasi aktif dalam kegiatan ini. Hasil evaluasi menunjukkan adanya peningkatan signifikan pengetahuan siswa dengan rata-rata kenaikan sebesar 70%, di mana siswa kelas V mencatat capaian lebih tinggi dibandingkan kelas IV. Dampak positif lain yang terlihat adalah keterampilan siswa dalam mencuci tangan dengan benar, meningkatnya kesadaran dalam memilih jajanan sehat, serta kemampuan memilah sampah sesuai jenisnya. Keberhasilan kegiatan ini menunjukkan bahwa pendekatan edukatif berbasis praktik langsung efektif untuk meningkatkan kesadaran dan membentuk perilaku sehat berkelanjutan pada siswa sekolah dasar.
