Faktor-Faktor Dalam Literasi Keuangan Yang Berpengaruh Terhadap Keputusan Investasi Emas Pelaku UMKM Di PT Bank Syariah Indonesia Tbk

Financial literacy plays a very important role in encouraging the accessibility of financial products and services provided by formal financial institutions. Several studies on financial literacy state that financial education will affect the level of financial literacy and a person's behavior in managing their finances. An adequate level of financial literacy is one of the keys to getting access to capital and better welfare. MSME actors must have the adequate financial literacy to participate in the financial sector and have access to financial services such as saving, buying insurance premiums, investing, obtaining credit, and others. Therefore, in an increasingly advanced era, basic financial knowledge and adequate skills are needed to manage economic and financial resources effectively as well as reliable risk management to achieve better welfare. Inadequate financial literacy can result in low access to financial institutions and hinder the achievement of welfare. The aim of the research is to identify the factors in financial literacy, to analyze the factors in financial literacy that influence the investment decisions of MSME actors, and to recommend alternative strategies to increase MSME literacy. This study uses primary and secondary data derived from filling out questionnaires by respondents and the opinions of experts through interviews. Based on multiple linear regression analysis, the financial literacy factors, namely Age (X1) and Gender (X2), each partially have no effect on the decision-making of MSME gold investment in Indonesian Sharia Banks, while Education (X3), and Income (X4) each partially has a significant effect on the gold investment decision of MSME actors in Indonesian Sharia Banks. The results of the SWOT and AHP analysis showed that the priority strategy in increasing financial literacy is creating promotional media about the benefits of investing in gold for MSME actors

Mastery of Basic Mathematics Facts in Slow Learner Children

As one of the mathematics objects, the basic facts of mathematics are the primary material that students must master. The facts of addition and subtraction should have been taught in the first level and mastered by the end of the second level. The multiplication and division facts should have been taught at the third level and could be mastered at the fourth level. The primary fact mastery phase consists of a counting phase, a reasoning phase, and a mastering/advanced phase. Mathematics as science should also be accepted by all students regardless of their characteristics, background, or physical needs. They must have the opportunity to learn and be supported to learn mathematics, one of which is a child with special needs slow learner. This research aims to describe the mastery of basic math facts in slow learner children. This is qualitative research, with research subjects totaling three slow learner students of Melana Junior Hight School, Semarang. Subjects are selected by purposive sampling.

MODEL PERAN ANTAR KELEMBAGAAN DESA DALAM PENYEDIAAN AIR BAKU MELALUI PARADIGMA KEPEDULIAN AIR (Studi Kasus Desa Bendungan, Kecamatan Ciawi, Kabupaten Bogor)

Based on water balance and temporal water sufficiency analysis in Ciliwung Hulu watershed, it shows that Ciseuseupan sub watershed belongs toinsufficient water category. Of the 8 villages in the Ciseuseupan sub watershed, there is a Bendungan village that is not enough water category in the provision of raw water, because in the provision of raw water is still dependent on natural reliability such as rivers, springs, wells, and others. This research discusses insufficient water solutions at the village level with one of them is institutional analysis through concern of water paradigm. The method used is ISM (Interpretative Structural Model), with emphasis on 4 (four) elements structured in relation to the provision of raw water ie: (1) needs of the program, (2) the main obstacle, (3) purpose program, and (4) institutions involved in program implementation. Therefore, it is required an independent water provision expert, involving various parties. The purpose of this research is to build an institutional role model in the provision of concern of water paradigm. The results show that: to realize a new paradigm in the provision of raw water, the main constraint is quality of human resources (village officials, communities, and NGOs), which must be resolved first, so that they can participate together to build the infrastructure by adequate socialization.   Berdasarkan analisis neraca air dan ketercukupan air temporal DAS Ciliwung Hulu menunjukkan bahwa Sub DAS Ciseuseupan termasuk ke dalam kategori kurang cukup air dalam penyediaan air baku. Dari delapan desa yang ada di Sub DAS tersebut, Desa Bendungan merupakan salah satu desa yang ketercukupan airnya termasuk dalam kategori tidak cukup, sebab dalam penyediaan airnya masih mengandalkan alam, seperti sungai, air tanah melalui sumur, mata air, dan lain-lain. Penelitian ini menjelaskan solusi ketidak cukupan di tingkat desa, dimana salah satunya adalah dengan analisis peran antar kelembagaan melalui paradigma kepedulian air. Metode yang digunakan adalah ISM (Interpretative Structural Model), yang menekankan pada empat elemen yang berhubungan dengan penyediaan air baku, yaitu: (1) kebutuhan program, (2) kendala utama, (3) tujuan program, dan (4) lembaga yang terkait dengan program. Oleh karena itu, diperlukan ahli penyediaan air mandiri, yang melibatkan berbagai pihak. Tujuan dari penelitian ini adalah membangun struktur model kelembagaan penyediaan air baku melalui paradigma kepedulian air. Hasil analisis menunjukkan bahwa: untuk merealisasikan paradigma baru di dalam penyediaan air baku,kendala utamanya adalah kualitas sumber daya manusia (aparat desa, masyarakat, dan LSM) yang harus diatasi terlebih dahulu agar mereka dapat berpartisipasi bersama-sama untuk membangun infrastruktur air melalui sosialisasi yang memadai
