Abstract

Abstrak. Saat ini, tandon air beton dengan metode “cor di tempat” masih menggunakan teknologi konvensional dan memakan waktu konstruksi yang lama. Pada penelitian ini dilakukan kebaruan melalui inovasi tandon air beton dengan metode “pracetak” sesuai karakteristik teknis SNI dan harga yang mampu untuk menembus pasar. Tahapan penelitian dimulai dengan investigasi ke pabrik pembuatan tandon air beton dan dilanjutkan dengan pengujian karakteristik material penyusun beton dan panel-panel pracetak dengan beberapa variasi diameter besi tulangan sebagai perkuatan. Kekuatan struktur diuji terhadap kuat desak dan kuat lentur. Penentuan diameter besi tulangan dilakukan dengan optimasi agar tandon air ini aman untuk diletakkan di bawah tanah yang berada di bawah garasi mobil keluarga. Kemudian, studi kelayakan ekonomi dilakukan melalui perhitungan harga pokok produksi, yang kemudian dibandingkan dengan harga pasaran melalui survei. Hasil penelitian menunjukkan bahwa panel pracetak sesuai standar SNI memiliki kuat desak beton rata-rata 25,8 MPa dan kuat lentur terendah 157,23 kg.m pada perkuatan dengan besi anyaman 2,6 mm. Tandon ini aman untuk diletakkan di bawah garasi mobil keluarga dengan faktor aman sebesar 187%. Perhitungan harga tandon air beton pracetak volume 1000 liter di Yogyakarta adalah sebesar Rp 1.300.000,00 yang relatif dapat bersaing dengan tandon air beton konvensional seharga Rp 1.350.000,00 dan tandon air stainless steel sebesar Rp 2.125.000,00. Abstract. Currently, concrete water tank with ”cast in situ” method has still been using conventional technology and needed long construction schedule. This novel research innovates concrete water tank with ”precast” method which corresponds to Indonesian Standard (SNI) and is able to compete in open market price. The stage of the research begun with an investigation to an existing plant of concrete water tank and testing of characteristic analysis of concrete material and precast panels with variety diameter of wiremess steel as reinforcement. Structural strengths of concrete panels were measured by compression and bending moment tests. The diameter of wiremess steel was decided through optimisation in which concrete water tank is significantly safe if burried beneath a family private garage. Then, an economy feasibility study to measure basic production costs was accomplished and this was compared with the normal price of open market. The research found that concrete panels fulfilled SNI with 25,8 MPa in compression strength test, the lowest bending moment was 157,23 kg.m for panels with 2,6 mm diameter of wiremess steel. This concrete water tank was safe when burried beneath a family private garage with safety factor of 187%. The price of 1000 litre of concrete water tank in Yogyakarta was Rp 1.300.000,00 in which it can compete with conventional concrete water tanks by price of Rp 1.350.000,00 and stainless steel water tanks by price of Rp 2.125.000,00.

Abstract

Islamic bank encounters a high financing risk because of scheme contract using the profit-loss sharing system leading to an agency problem. The non-performing financing of Islamic rural banks as small Islamic banks in Indonesia is above the maximum threshold and is higher than that of conventional rural banks as their competitors. This paper investigates the impact of bank characteristic variables and macroeconomic variables on the non-performing financing of Islamic rural banks. Our study employs aggregate Islamic rural banks data, spanning from January 2009 to December 2018. Non-linear autoregressive distributed lag model (NARDL) is applied to address this issue. Capital adequacy ratio obviously increases impaired financing and income diversification clearly reduces non-performing financing. More interestingly, domestic output and inflation have an asymmetric effect on non-performing financing. Economic downturns increase non-performing financing but economic upturns have no impact on non-performing financing. Meanwhile, inflation deteriorates non-performing financing but deflation does not reduce non-performing financing.

Abstract

Purpose: This study aims to determine the effect of non-performing finance, inflation, interest rates, Bank Indonesia Sharia Certificate variable, deposit and Industrial Production Index on the financing of the agricultural sector in Islamic banks.Methodology:This study uses analysis tools with the Vector Auto Regression (VAR) method. The VAR method is applied if the data used is stationary and there is no cointegration. If the data used is stationary but there is cointegration, the analytical tool that will be applied is the Vector Correction Model (VECM) method.Findings: There is causality between interest rates and financing in the agricultural sector. This situation can be interpreted that any increase in interest rates will result in people preferring financing to Islamic banks. Profit sharing and margins do not directly influence the increase in interest rates in conventional banks so that the increase in interest rates is relatively a cheaper cost of financing. Conversely, if there is a decrease in the interest rate on conventional banks, it will make people more likely to choose financing in conventional banks rather than in Islamic banks      Originality:This study enrich the discussion in factors affecting financing with Islamic Banks in agriculture sectors.

Abstract

This study examines the impact of liquidity on Islamic banks profitability during the years from 2014 to 2019. The study extracted its data from the annual reports of six Islamic banks in Indonesia that have been in operations on or before 2014 to 2019. The liquidity model is built from four liquidity variables namely financial to debt ratio (FDR), liquid asset to total asset (LATA) dan liquid assets to deposits (LAD). The results of the study show that FDR is correlated negatively with ROA and NOM, but correlated positively with ROE. Thus, LAD indicate a positive correlation with ROA and NOM. And, LATA found to be significant with ROE at 0,05 Significant level.

Abstract

Purpose – This study empirically analyzes the effect of the financing diversification with some control variables including both bank-specific variables such as bank's size, CAR, efficiency and the macroeconomic variables such as the inflation and exchange rate, on the Islamic bank's non-performing financing (NPF).Methodology – The aggregate Islamic bank data encompassing Islamic commercial banks and Islamic business units are used. The Autoregressive Distributed Lag Model (ARDL) is employed using the monthly data covering January 2011 to December 2019.Findings – The cointegration test indicates that the long-run relationship among variables being studied exists. Our results document that higher concentrated financing generates high NPF. Higher asset significantly contributes to reducing NPF. In addition, higher operating efficiency can reduce NPF. The instability of the exchange rate also generates the high NPF.Research limitations – This study employs aggregate data but applying them may conceal for individual Islamic bank.Practical implications – Our results suggest that Islamic banks must lessen the high concentrated financing by optimizing both PLS and non-PLS contracts to reduce Islamic banks' financing risk.Originality – Our study includes financing diversification to examine Islamic bank's financing risk. The existing empirical studies, to the best of our knowledge, have not addressed the impact of financing diversification on financing risk.

Abstract

Berwirausaha merupakan salah satu cara yang dapat ditempuh untuk membangun kemandirian ekonomi. Menumbuhkan jiwa wirausahan dapat dilakukan dengan memberikan pelatihan ketrampilan kepada generasi muda terutama yang memiliki keterbatasan untuk mengakses pendidikan tinggi seperti anak-anak panti asuhan. Permasalahan yang dihadapi oleh anak-anak panti asuhan adalah keterbatasan dana sehingga mereka hanya mampu menyelesaikan pendidikan Sekolah Menengah Atas (SMA). Karena rendahnya pendidikan mereka tidak mampu bersaing untuk mendapatkan pekerjaan yang layak. Berdasarkan latar belakang tersebut maka dilakukan kegiatan pengabdian dengan memberikan pelatihan ketrampilan menjahit bagi anak-anak panti asuhan. Tujuan dari kegiatan ini adalah untuk menumbuhkan jiwa kewirausahaan sehingga anak-anak panti dapat membangun usaha secara mandiri. Disamping itu kegiatan ini bertujuan untuk memberikan ketrampilan yang sebelumnya tidak diperoleh dibangku sekolah. Metode pelaksanaan diawali dengan memberikan motivasi berwirausaha melalui pendekatan yang santai dan menyenangkan agar anak-anak merasa nyaman. Metode selanjutnya yaitu memberikan pelatihan ketrampilan menjahit mulai dari proses membuat pola hingga praktik menjahit. Hasil dari kegiatan pengabdian ini adalah anak-anak panti asuhan memiliki ketrampilan menjahit sehingga mampu membuat pakaian sendiri. Kegiatan pengabdian ini juga membuka pengetahuan baru bagi anak-anak tentang kewirausahaan yang dapat digunakan sebagai bekal ketika mereka lulus sekolah. Kata kunci : Panti Asuhan Ghifari, ketrampilan, kewirausahaan
