Based on the 2016-2020 Central Java Disaster Risk Assessment, floods and landslides are the most frequent disasters, with 818 flood cases accounting for 31.33% of the total disasters and landslides accounting for 29.57%. This study aims to cluster disaster-prone areas in Central Java using the K-Means algorithm and the GeoPandas library. Data on disaster events for the period 2019-2023 was obtained from the National Disaster Management Agency, while administrative map data of Central Java was downloaded from the Geoportal of Central Java Province. The research stages include data collection, data cleaning, standardization using the Standard Scaler method, application of the K-Means algorithm for regional clustering, and visualization of results using GeoPandas. The results showed that Central Java was divided into four clusters, namely: cluster 0 (disaster-prone areas) includes 3 regions, cluster 1 (non-disaster-prone areas) has 22 regions, cluster 2 (flood-prone areas) consists of 7 regions, and cluster 3 (landslide-prone areas) has 3 regions. The results of this research provide spatial data-based information that can be used as a basis in decision-making for disaster mitigation in Central Java.

Gunthem Coffee is a cafe located in Semarang as well as a foodtruck when there is an event. Gunthem Coffee provides 20 coffee menus. The large number of coffee menus that spoil consumers, Gunthem Coffee decided to make policies for marketing strategies. Based on the problems experienced by Gunthem Coffee, it is necessary to conduct research on consumer interest patterns so that it will benefit both Gunthem Coffee and consumers. This research uses the a priori algorithm based on field data that can be calculated objectively. The results obtained from the apriori algorithm calculation are to get two (2) association rules with a minimum support of 30% and a minimum confidence of 60%, namely if you buy Black Pink, you will buy Kopi Susu Sanger with a support value of 50% and a confidence value of 67% and if you buy Sanger Milk Coffee, you will buy Black Pink with a support value of 50% and a confidence value of 87%.

Dalam pendidikan modern, teknologi sangat diperlukan untuk meningkatkan proses belajar mengajar. Namun, di SMA Negeri Saengga, meskipun telah diberikan 80-an gadget bantuan oleh pemerintah, guru dan siswa masih belum memanfaatkan teknologi secara optimal dalam proses belajar mengajar. Untuk mengatasi hal ini, dilakukan workshop dan bimbingan teknis kepada guru dan siswa agar mereka terbiasa menggunakan teknologi yang tersedia dalam proses belajar mengajar. Hasilnya, guru dapat membuat presentasi materi pelajaran menggunakan MS.Powerpoint dan membuat kuis online dengan Kahoot dan Quizizz. Selain itu, siswa menjadi semakin termotivasi untuk mengerjakan kuis online karena ini memberikan pengalaman baru bagi mereka.

Karyawan dalam suatu perusahaan merupakan bagian terpenting yang mempengaruhi tingkat kemajuan suatu perusahaan, maka perlu adanya peningkatan kualitas sumber daya manusia. Salah satu upaya yang dapat dilakukan adalah dengan cara penilaian kinerja karyawan. Beberapa perusahaan yang ada sudah menerapkan penilaian kinerja karyawan namun kurang efektif karena dilakukan secara manual sehingga terjadi penumpukan berkas dan bisa terjadi kesalahan dalam perhitungan penilaian. Oleh karena itu dirancang sebuah sistem penilaian kinerja karyawan berbasis website yang berisi hasil implementasi metode TOPSIS. Data dikumpulkan dengan menggunakan teknik observasi, wawancara, dan studi pustaka. Hasil akhir penelitian ini berupa nilai preferensi yang akan ditampilkan dalam bentuk peringkat. Berdasarkan analisis kepuasan pengguna diperoleh nilai 3.58 yang tergolong dalam puas sehingga layak digunakan oleh user. Sistem penilaian kinerja karyawan yang dihasilkan ini dapat digunakan untuk membantu mempermudah penilai dalam memberikan penilaian, mempercepat proses penilaian, serta mengurangi penumpukan berkas.

In order to improve institutional capabilities, UKSW needs to collaborate with various parties. Documents of agreement which is the references of implementation must be archived and managed properly. The document of agreement in UKSW, still manage manually, making it difficult to find complete data related to the cooperation agreement that has been made by UKSW.  Information technology has an important role in increasing the efficiency and effectiveness of the document management and archiving. This study aims to develop a cooperation information system that capable to record the whole process of submitting agreement, until the process of archiving the signed document. Rapid Application Development (RAD) method used with the aim of accelerating development process, providing good quality of system, and reducing development and maintenance costs. The result of this research is a cooperation information system that has been implemented at UKSW Salatiga.
