Climate change is a global phenomenon, where the impact will be experienced by all parts of the world. One of the areas studied was Indonesia. Climate change in Indonesia has the direct and indirect effect on aspects of human life. Climate change can cause ecosystem disturbances. One of which is a mountainous ecosystem on Mount Rinjani, Lombok Island. The mountain ecosystem is very similar to the climate in Indonesia, this will have a special impact on the agricultural sectors. Therefore it is necessary to know the level in their environment. This paper will discuss social measurement parameters and their impact on climate in mountain ecosystems. The main factors are ecosystems (control environment, settlement patterns), ecology (forest cover, cliff conditions) and economy (livelihood & income / natural resources).

This research is aimed at producing product in the form of material content developed in a web format in the form of a material page and assignment page to make students easily in the learning process. This study used the Research and Development (R&D) method with the 4D model as a guide for developing an effective product. The research procedure is to determine the learning requirements, design the required learning media, developed the learning media that had been designed, and disseminate the result of the product developed to students. The research results obtained in this study were the Padlet media feasibility test which scored 92.30% in the “Very Eligible” category for media validation and 93% in the “Very Eligible” category for material development. This development research showed that this Padlet media could involve students actively in the learning process.Keywords: Learning Media; Padlet; Recount Text

Keamanan jaringan pada server sangat penting, karena server adalah titik utama dalam penyaluran jaringan internet, jika keamanan jaringan lemah maka orang yang tidak berkepentingan dapat dengan mudah melakukan serangan terhadap server, baik untuk mendapatkan internet secara gratis atau merubah sistem pada server. Di Barokah.net sistem keamanan yang digunakan hanya pada login ke akses server dan menggunakan IP Static untuk identitas pada modem client, seiring berjalannya waktu di temukan ip address illegal yang muncul pada daftar IP ARP Mikrotik dan penyerangan menggunakan Brute Force yang terdeteksi pada Log sistem Mikrotik. Berfokus pada masalah tersebut penggunaan metode IP Filtering dan Port Knocking pada server utama merupakan cara yang tepat untuk meningkatkan sistem keamanan jaringan, dimana IP Filtering dan Port Knocking akan memberikan sebuah daftardan autentikasi khusus agar perangkat yang ingin mendapatkan akses ke server dapat di perbolehkan oleh server. Sehingga metode IP Filtering dan Port Knocking dapat meningkatkan keamanan jaringan pada Barokah.net.

Sampah merupakan hasil dari aktivitas manusia sehari – hari dan atau proses alam dalam bentuk padat. Desa Bulakan termasuk desa dengan industri penggergajian kayu yang menghasilkan sampah serbuk gergaji kayu yang masih belum dimanfaatkan baik oleh masyarakat. Upaya yang dapat dilakukan untuk mengurangi timbulan sampah yaitu dimanfaatkan menjadi briket. Tujuan penelitian untuk mengetahui pengaruh bentuk briket terhadap lama waktu didih air. Metode yang digunakan yaitu pre eksperimen rancangan One Shot Case Study dengan uji Kruskal Wallis dan uji lanjut Mann Whitney U. Hasil uji statistik Kruskal Wallis terhadap bentuk briket menunjukkan nilai Sig 0,002 0,05. Artinya ada pengaruh bentuk briket kubus pejal, kubus berongga, silinder pejal dan silinder berongga terhadap lama waktu didih air. Selanjutnya dilakukan uji Mann Whitney U. Rerata waktu mendidihkan air pada bentuk kubus pejal 618,3 detik, kubus berongga 590,5 detik, silinder pejal 562,6 detik, dan silinder berongga 511,1 detik. Simpulan dari penelitian ada pengaruh ada pengaruh bentuk briket sampah serbuk kayu terhadap lama waktu didih air. Saran bagi peneliti selanjutnya menambah variasi bentuk lain dan mengkombinasi biomassa yang berbeda.

The emergence of the food crisis in Bandung City due to COVID-19 has prompted the local government to create an integrated urban farming program. This program is called Buruan Sae. This program aims to support food security for the people of Bandung. One of the targets is located in Jatisari, Buah Batu, Bandung. In that area, the program has been successfully implemented and has reached 22 times harvests. However, unfortunately, the residents in the area still have a low level of participation in the Buruan Sae program. According to this problem, the researchers would like to conduct a study to evaluate the integrated urban farming in Buruan Sae. This study uses qualitative methods for data collection through interviews. The results of this study show that the low level of participation in the Buruan Sae program in Jatisari occurred since the benefits of this program cannot be felt equally by all residents of Jatisari. Only residents of RW 02 can feel the positive impact of the harvest achieved through the Buran Sae Program. Meanwhile, based on effectiveness, efficiency, adequacy, responsiveness, and accuracy, integrated urban farming has succeeded in meeting the indicators and is worthy of being used as a food security policy program.
