Abstract

Indonesia is an importing country that frequently imports goods from abroad continuously every year. Imported goods are oil and gas and non-oil and gas. Oil and gas includes oil and gas. This oil and gas import value data is an example of time series data, where the data is obtained from data recapitulation at the Central Bureau of Statistics (BPS). Time series analysis is a method for predicting an event that will come by looking at data from the previous time. One of the newest methods of time series analysis used in this research is Fuzzy Time Series Chen method. The purpose of this research is to find out how the implementation of Fuzzy Time Series Chen method in predicting the value of Indonesian oil and gas imports and to know the results of forecasting the value of Indonesian oil and gas imports. In predicting the value of Indonesia's oil and gas imports using Fuzzy Time Series Chen method, the results of forecasting the value of Indonesia's oil and gas imports in August 2022 were US$ 3743.213 million with a MAPE value of 19.969%.

Abstract

The Fuzzy Time Series (FTS) was first studied by Song and Chissom based on the theory of fuzzy sets and the concept of linguistic variables and their applications discovered by Zadeh. FTS has several models, namely FTS Lee, FTS Tsaur, and so on. In this study, we will model earthquake frequency data in Mentawai using FTS Lee and FTS Tsaur. The seismicity data used in this study is earthquake frequency data in the Mentawai which are calculated from 1960 to 2022. Additionally, the seismicity data source is taken from the U.S. Geological Survey catalog. Based on MAPE and MSE, the results obtained on the FTS Lee and FTS Tsaur models are MAPE values of 37,511% and 27,051%. And the MSE values obtained were 27,073 and 11,671. Thus, the best model used in modeling data on the frequency of earthquake occurrences in the Mentawai Islands is the Ruey Chyn Tsaur Fuzzy Time Series model.

Abstract

This study introduces the design and evaluation of an automatic roof drive prototype aimed at optimizing tomato cultivation. Developed to address the challenges of erratic weather, the system seeks to enhance the efficiency of tomato farming. The prototype integrates a weather sensor, microcontroller, and roof drive mechanism, allowing it to operate automatically based on real-time environmental conditions. Effectiveness was assessed through field trials measuring key growth parameters such as plant height, fruit number, and fruit quality. Results indicate that the automatic roof drive system significantly improves both the productivity and quality of tomato crops. Additionally, the system effectively mitigates losses due to extreme weather conditions, including heavy rain and excessive heat. These findings highlight the potential of automated roof drive technology to support more efficient and sustainable agriculture. Future work will focus on refining the system for broader applications and integrating advanced technologies such as IoT and machine learning for further optimization.

Abstract

Operasi pada hipergraf adalah suatu cara untuk mengkonstruksi suatu hipergraf dengan struktur yang lebih besar. Salah satu operasi pada hipergraf yang biasa dipelajari adalah operasi kali Kartesius. Suatu hipergraf dikatakan integral jika semua nilai karakteristik dari matriks ketetanggaannya adalah bilangan bulat. Dalam makalah ini, dipelajari dua kelas hipergraf yaitu, bidang Fano dan latin square orde 3. Dapat ditunjukkan bahwa kedua kelas hipergraf tersebut adalah integral. Selanjutnya, ditentukan hipergraf hasil operasi kali Kartesius dari kedua hipergraf tersebut. Dapat dibuktikan bahwa operasi kali Kartesius pada hipergraf mempertahankan sifat keintegralan.

Abstrak. Mayoritas warga Desa Candisari, Kecamatan Windusari, Kabupaten Magelang, Jawa Tengah, tidak melanjutkan pendidikan setelah menyelesaikan pendidikan sekolah dasar Hal ini menjadi salah satu penyebab rendahnya budaya literasi dan pemahaman mereka terhadap berbagai aspek yang berkaitan dengan kehidupan masyarakat, sehingga diperlukan upaya untuk meningkatkan budaya literasi. Salah satunya lewat pengadaan perpustakaan desa. Hasil observasi menunjukkan bahwa sarana dan prasarana Perpustakaan Desa Candisari masih terbatas. Kegiatan pengabdian masyarakat ini bertujuan untuk mengembangkan perpustakaan di Desa Candisari untuk meningkatkan budaya literasi masyarakat setempat. Tahapan pengabdian ini adalah observasi, koordinasi, pelaksanaan kegiatan, dan penginformasian atau sosialisasi. Hasil kegiatan ini berupa tercapainya penambahan koleksi bahan bacaan, klasifikasi bahan bacaan, pemberian label identitas pada bahan bacaan, penataan, dan pengategorian bahan buku. Lewat kegiatan ini, diharapkan budaya literasi warga masyarakat Candisari meningkat.Abstract. The majority of residents of Candisari Village, Windusari District, Magelang Regency, Central Java, do not continue their education after completing elementary school. This is one of the causes of low literacy culture and their understanding of various aspects related to community life, so efforts are needed to improve literacy culture. . One of them is through the provision of a village library. The observation results show that the facilities and infrastructure of the Candisari Village Library are still limited. This community service activity aims to develop a library in Candisari Village to improve the literacy culture of the local community. The stages of this service are observation, coordination, implementation of activities, and information or socialization. The results of this activity are the achievement of increasing the collection of reading materials, classifying reading materials, giving identity labels to reading materials, arranging and categorizing book materials. Through this activity, it is hoped that the literacy culture of the Candisari community will increase.Keywords: Literacy; Village Library; Reading Habit

Abstract

Penuaan yang sukses (successful aging) merupakan tujuan penting dalam meningkatkan kualitas hidup lansia. Namun, lansia di panti kerap menghadapi keterbatasan dalam interaksi sosial, dukungan emosional, serta aktivitas fisik yang beragam, yang dapat menghambat tercapainya kondisi ideal tersebut. Penelitian ini bertujuan untuk mengeksplorasi pengalaman lansia dalam menjalani masa tua di Panti Werdha Elim dengan menggali makna lansia terkait kesejahteraan, dukungan sosial, dan tantangan yang mereka hadapi dalam kehidupan sehari-hari. Penelitian ini menggunakan pendekatan kualitatif dengan pengumpulan data dilakukan melalui tiga teknik, yaitu observasi, wawancara dan dokumentasi. Hasil penelitian menunjukkan bahwa lansia yang berada di panti jompo masi bisa melakukan aktivitas harian secara mandiri, secara kesejahteraan psikologis para lansia mampu menerima diri meskipun merasa kesepian, bagi para lansia panti dapat menjadi tempat interaksi sosial yang suportif, dan aktivitas spiritual memberikan ketenangan batin. Temuan ini menegaskan pentingnya dukungan komprehensif untuk mendukung kualitas hidup lansia dalam kerangka successful aging.

Abstract

This research aims to determine the meaning behind the cover of the 11-17 November 2019 issue of Tempo magazine with the main title "Anies' Budget Disgrace", which includes a caricature of one of the national figures, so as not to cause wild opinions and noise in the community. This research uses a qualitative approach method that produces descriptive data, with primary data obtained from the documentation of Tempo magazine and secondary data obtained from relevant literature and journals. The collected data is then analysed using Charles Sanders Pierce's semiotics with its trichotomous concept. The results of this study show that Tempo magazine has fulfilled its function of social control and is directly involved in monitoring issues of public interest. The caricature of Anies, depicted by Tempo as trapped in DKI Jakarta's budgeting system, is depicted as falling into a can of glue. The can is a packet of Aica-Aibon glue, which is believed to be one of the budget items with a fantastic purchase value.Keywords: controversy, cover magazine; semiotics; tempo
