Dissolved oxygen and suspended sediment are the most important parameters used to assess the water quality of the river. The concern of freshwater pollution problems in Malaysia since the past few decades has resulted in the importance of monitoring dissolved oxygen concentration as a barometer for river health. This study attempted to identify the spatial and temporal distribution of dissolved oxygen and suspended sediment in the Kelantan River Basin, Peninsular Malaysia. Water samples were collected during dry and wet seasons at three sampling stations along the

Mega Florist Bandar Lampung is a company engaged in the field of flower board rental and delivery services in the Bandar Lampung area, Mega Florist itself has been established since April 2015. The purpose of this research is to design an e-marketing system and implement an e-marketing system as a customer service at Mega Florist Bandar Lampung. The problem with Bandar Lampung's Mega Florist itself is that there is no system to market board flower rentals, and its marketing still uses brochures, print media, and advertisements so that it requires more costs to market board flower rental services to Mega Florist Bandar Lampung. The system development method uses the waterfall method and the system design uses the UML system design, and the system implementation uses an object-based programming language that is PHP, with Dreamwever and MySQL applications as a database. The result of this research is an online application based on e-marketing built by Mega Florist Bandar Lampung, focused on spreading information on package rental and flower delivery. This web board will present services, facilities, menus, promos and provide convenience for customers in finding information interest rates offered, as well as services in booking board interest rentals.

Groundsill is a transverse threshold structure that can be built on water body as one alternative in reducing the upstream water velocity and therefore could maintain the upstream sedimentation rates. Due to scouring problems faced in the Cimadur River, Banten Province, a groundsill structure has been constructed at one location in Cimadur River which is near to the Bantar Karang bridge structure. The scouring problem is worried to damage the abutment of the bridge structure. This study aims to investigate the effectiveness of the groundsill structure in reducing the scouring problem in Cimadur River, Banten Province. The effectiveness is determined by comparing the riverbed elevation around the Bantar Karang bridge structure, before and after 5 months construction of the groundsill structure. The results showed that the presence of the groundsill structure has increased the riverbed elevation especially around the abutment of the Bantar Karang bridge (approximately 25 cm in average after 5 months installation of the groundsill structure). It is therefore can slowly reduce the local scouring problem around Bantar Karang bridge. Besides, the results also showed that there is small reduction of riverbed elevation at the downstream area of the groundsill structure approximately about 10 cm in average. It can be concluded that the groundsill structure is quite effective in reducing the local scouring problem in Cimadur River, especially upstream area of their structure around Bantar Karang bridge.

Banjir adalah masalah umum yang sering terjadi di wilayah Indonesia, terutama diwilayah padat penduduk, contohnya di daerah perkotaan. Kerugian yang ditimbulkan aibat banjir cukup besar, baik dari segi materi maupun kerugian jiwa/kematian, maka dari itu permasalahan banjir perlu mendapatkan perhatian yang serius. Salah satu masalah banjir yang masih menjadi pusat perhatian saat ini adalah masalah banjir di Sungai Cimadur, Provinsi Banten Hasil analisis debit kala ulang 5 tahun, 10 tahun, 25 tahun dan 50 tahun dihitung menggunakan Metode Polygon Thiessen dengan hasil debit pada kala ulang 5 tahun sebesar 101,6100 m3/s, kala ulang 10 tahun sebesar 127,2145 m3/s, kala ulang 25 tahun sebesar 199,4511 m3/s dan kala ulang 50 tahun sebesar 165,7435 m3/s. Debit banjir yang telah didapatkan digunakan untuk melakukan running Program Hec-Ras dengan hasil analisis mengenai tinggi muka air banjir pada bagian hilir Sungai Cimadur pada titik 1 sampai dengan titik 8 mengalami banjir pada seluruh titik yang dianalisis. Banjir di titik-titik analisis memiliki perbedaan tinggi muka air banjir yang berbeda, letak banjir yang berbeda yaitu ada pada bagian kanan dan ada pada bagian kiri sungai serta ada juga pada yang terjadi pada keduanya. Kata Kunci: Banjir, Debit, Polygon Thiessen, Tinggi Muka Air Banjir.

SMK Negeri 1 Trimurjo dituntut untuk berkembang dengan cepat agar mutu pendidikan dapat menyaingi SMK lain yang sudah lebih dahulu berdiri. Kegiatan pengabdian kepada masyarakat pada SMK Negeri 1 Trimurjo bertujuan untuk mengembangkan sarana sekolah dan meningkatkan sumber daya tenaga pengajar, staf, dan siswa. Berdasarkan hal tersebut maka perlu disusun beberapa program peningkatan mutu pendidikan untuk SMK Negeri 1 Trimurjo. Program pengabdian yang ditawarkan yaitu pelatihan desain green building. Pelatihan konsep green building tentu dapat menambah ilmu pengetahuan tenaga pengajar dan siswa sehingga dapat meningkatkan mutu pendidikan. Belum adanya topik mengenai konsep Green Building pada mata pelajaran di jurusan Desain Pemodelan dan Informasi Bangunan membuat terbatasnya pengetahuan terkait bangunan dengan konsep Green Building. Metode pelaksanaan pengabdian kepada masyarakat untuk sekolah binaan terdiri dari lima tahapan kegiatan inti, yaitu: Persiapan, Pelaksanaan dan Perencanaan, Pelatihan dan Pendampingan, Monitoring dan Evaluasi, serta Pelaporan dan Publikasi. Kegiatan Pengabdian Kepada Masyarakat ini diharapkan dapat menambah keahlian tenaga pengajar, siswa, dan staf sehingga mutu pendidikan SMK Negeri 1 Trimurjo dapat lebih terangkat.
