Abstract

The curriculum for santriwati in Islamic boarding schools encompasses not only religious studies but also the development of entrepreneurial skills. One such skill with potential economic value is wood photo transfer (WPT), which utilises wood as the basic material. The selection of this extension theme was based on the availability of wood raw materials in various sources around the boarding school. The objective of the counselling was to provide female students at the pesantren with information and skills on WPT making techniques. The counselling involved a theoretical explanation of the material and a practical demonstration of wood-based WPT. A total of 14 female students at one of the Islamic boarding schools in Samarinda received hands-on training in making WPT. Of the trainees, 50% were able to complete the practice of making WPT. The skills required to produce WPT can be developed in order to pursue hobbies or as a potential business opportunity with the aim of increasing the income of santriwati.

Abstract

Resilience is an important character for career women. Resilience is needed so that dual-role career women can balance career and family. Internal and external factors in career women can also affect their psychological resilience in undergoing dual roles. This study aims to determine how the description of resilience abilities in dual-role career women. The method used is qualitative research with a phenomenological approach. The subjects taken were four dual-role career women at Mulawarman University, Samarinda City, East Kalimantan. The research was conducted using in-depth interview method. Data analysis was done by data reduction, categorization, and data presentation. The conclusion of the results showed that the four subjects had high resilience, because they fulfilled five aspects of resilience, namely personal competence, trust in instincts, positive self-acceptance of change, control, and spiritual influence. Suggestions for further research may be able to conduct more in-depth interviews and observations, because researchers can only interview online because they are in different cities.

Abstract

Mining activities led to land degradation, which in turn resulted in food insecurity. Additionally, it limited post-mine plant growth actions but did not initiate any new actions. The drawings describe the involvement of soils resulting from various land uses following degradation actions, including agriculture, forestry, and other land uses. It gives an overall description of the activities and processes. The primary factors involved in land degradation include structural changes in soil, pH, and the activity of various components. The Liquid Soil Conditioning (LSC) solution developed in the study provides a resource that can be used as an application option for land restoration. This study evaluated the post-coal mining problem in West Samboja, East Kalimantan Province, Indonesia. It offers a prospect to understand soil conditions related to the availability of essential nutrients and microorganisms. This study examined various physical, chemical, and?biological characteristics of the soil. The results showed that LSC can make land management more sustainable. The LSC can mitigate the opposing effects on soil and support beneficial?soil microbes. This innovation not only restores damaged land and makes it more suitable for planting, but also increases land production and supports the other functions of the natural ecosystem. Those working in land restoration should conceivably use LSC more?frequently. This method can?support more sustainable post-mining land management when accompanied by regular soil monitoring and further research in advance.

Abstract

Kegiatan pertambangan terbuka di PT Kideco Jaya Agung telah menyebabkan perubahan signifikan pada karakteristik fisik dan kimia tanah serta tutupan lahan. Proses penambangan sering merusak lapisan topsoil yang kaya bahan organik serta penting untuk infiltrasi air dan permeabilitas tanah. Penelitian ini bertujuan untuk mengetahui sifat fisik dan kimia tanah, mengukur laju infiltrasi dan permeabilitas tanah di PT Kideco Jaya Agung. Sifat-sifat fisik tanah yang diuji adalah struktur tanah, tekstur tanah, porositas, kerapatan lindak, dan kadar air. Sedangkan beberapa sifat kimia tanah yang dianalisis meliputi pH, C-organik, bahan organik, N-total, C/N rasio, dan P2O5 dan K2O. Pengukuran laju infiltrasi dilakukan dengan menggunakan double ring infiltrometer, sedangkan sampel permeabilitas diambil menggunakan ring sampel dan diuji di laboratorium. Hasil menunjukkan laju infiltrasi tertinggi di arboretum (58,75 cm/jam, kelas sangat cepat), diikuti lahan revegetasi (4,32 cm/jam, kelas sedang), dan area disposal top soil (1,58 cm/jam, kelas agak lambat). Permeabilitas di arboretum sebesar 1,26 cm/jam (kategori agak lambat), lahan revegetasi sebesar 0,98 cm/jam (kategori agak lambat), dan area disposal top soil sebesar 1,21 cm/jam (kategori agak lambat). Informasi tentang sifat fisik dan kimia tanah, laju infiltrasi, dan permeabilitas tanah pada kawasan pertambangan dapat menjadi bahan pertimbangan dalam merumuskan strategi reklamasi yang efektif.

Abstract

This paper presents a generalized implementation of the cycle joining algorithm for generating binary sequences corresponding to modified de Bruijn sequences of order . The proposed approach can be interpreted in terms of a modified de Bruijn graph, where vertices represent binary strings of length and edges correspond to allowable transitions under the modification rules. The algorithm can be applied to any integer  and can start from any chosen initial vertex. The procedure begins by constructing an initial sequence using the prefer-complement algorithm. The method can produce multiple disjoint cycles, which are iteratively extended and joined into a single sequence. A key challenge in cycle joining is identifying suitable conjugate pairs for merging cycles. In this approach, conjugate pairs are efficiently determined through the algorithm’s structured scheme, simplifying the joining process. The resulting sequence achieves the maximal length , which corresponds to a modified de Bruijn sequence. The flexibility of the algorithm allows it to accommodate varying initial vertices, making it highly adaptable for sequence generation. Its ability to systematically join multiple cycles into a single sequence corresponding to a modified de Bruijn sequence demonstrates potential applications in cryptographic keystream generation, pseudorandom binary sequence design, and other areas requiring structured yet complex binary sequences.
