Abstract

Bawang merah merupakan produk pertanian khususnya hortikultura yang memiliki peranan penting di Indonesia dengan dimasukkan sebagai salah satu bahan pangan utama. Permintaan bawang merah yang tinggi dan produksi yang bersifat musiman menjadikan harga bawang merah fluktuatif dan cenderung meningkat setiap tahunnya. Analisis ARIMA adalah salah satu metode yang digunakan untuk peramalan data time series. Tujuan dari penelitian ini adalah untuk peramalan harga konsumen bawang merah di Provinsi Jawa Tengah. Data yang digunakan dalam penelitian ini adalah data harga konsumen bawang merah di Provinsi Jawa Tengah dari aplikasi Pusat Informasi Harga Pangan Strategis (PIHPS) yang diakes pada lama hargapangan.id. Data yang digunakan untuk analisis ARIMA merupakan data harga konsumen bawang merah di Provinsi Jawa Tengah dari Bulan Juli tahun 2017 sampai Bulan April tahun 2021 dengan total jumlah data adalah 46 data harga konsumen. Berdasarkan hasil penelitian dapat disimpulkan bahwa model ARIMA terbaik yang digunakan untuk peramalan harga konsumen bawang merah di Provinsi Jawa Tengah adalah ARIMA c(3,1,2). Model harga konsumen bawang merah di Provinsi Jawa Tengah adalah D(Y)=-0.254657AR(3)-0.586703MA(2). Peramalan harga konsumen bawang merah di Provinsi Jawa Tengah sampai Bulan April tahun 2022 dengan menggunakan metode dinamis diperoleh data harga konsumen yang terus meningkat.

Abstract

According to data from the Kementerian Lingkungan Hidup dan Kehutanan (2022), waste production in Indonesia is around 36 million tons per year and unmanaged waste is around 13.5 tons per year (37.45%). Waste production in Daerah Istimewa Yogyakarta is around 800 thousand tons per year, and  50.17% of it is household waste. The total volume of waste brought to the Piyungan landfill is around 700 tons/day, around 55 percent of it is organic waste. Each person produces around 0.68 kg of waste per day, so waste management must be the responsibility of all people communities as waste producers. The aim of community service activity is to increase knowledge, skills and motivate also raise awareness of KWT Cabe Rawit members in Jambon Village as partners in processing household waste into eco enzyme and Liquid Organic Fertilizer using the stacked bucket technique, so that it can support the zero waste movement. The implementation methods in community service activities including lectures, training and practice. The outputs that will be produced are publications in national seminar proceedings with ISBN, publications in electronic mass media, books with ISBN, videos, posters and increasing partner empowerment. All members of the KWT Cabe Rawit members in Jambon Village understand and are skilled in making eco enzymes and Liquid Organic Fertilizer from organic household waste and their benefits. The quality of Liquid Organic Fertilizer using the stacked bucket technique is an organic C content of 2.76%, 0.14% total N, C/ N 19.71, P2O5 0.0041 %, K2O 0.023% and pH 5.7. The quality of compost using the stacked bucket technique is organic C content 42.26%, total N 3.67%, C/N 11.51, P2O5 0.39%, K2O 0.17% and pH 6.2 and pH eco enzyme 3 .5Keywords: Eco enzyme, Household waste, Liquid organic fertilizer, Zero waste

Abstract

Shallots represent a significant component of Indonesia's vegetable crop production. They are widely consumed across the country, leading to an annual increase in demand. However, shallot production tends to remain stable or even decline, resulting in supply and price instability. In the Special Region of Yogyakarta, shallots are a prominent horticultural commodity with substantial production. Producer prices for shallots in this region exhibit fluctuations, particularly at the producer level compared to wholesale or consumer prices. Forecasting producer-level shallot prices utilizes the ARIMA (Autoregressive Integrated Moving Average) method, chosen for its accuracy in short-term time series prediction. Data sourced from the Strategic Food Price Information Center (PIHPS) via the hargapangan.id platform includes consumer prices and spans from January 2019 to May 2024. The analysis reveals that producer prices in the Special Region of Yogyakarta are influenced by previous month price increases, with the optimal ARIMA model identified as ARIMA (1,0,0) with the equation D(Y) = 21885.24 + 0.569977AR(1), as determined by the study findings.Keywords: ARIMA, Forecasting, Producer Prices, Shallots

Abstract

Hydroponics is the cultivation of plants using water or without the use of soil. Hydroponics is one of the limited land acquisitions. Hydroponics development can be done at Madrasah Aliyah Madania Bantul, but it requires special skills for students who take extracurricular agriculture and livestock. The problem is limited land at the location of Madrasah Aliyah Madania Bantul. Land has not been utilized, hydroponic cultivation has not been implemented to the fullest, and students' knowledge and skills are still limited about hydroponics. The methods used are lectures, discussions, training, practice and mentoring. The implementation of activities at the location of Madrasah Aliyah Madania Bantul school at Pondok Pesantren Modern Yatim and Dhuafa Madania Jl Gedongkuning Gang Nakula No. 165 Banguntapan Bantul. The activity began in June 2021, the number of participants was 15 people. The result of community service that madrasah madania bantul students already have life skills about hydroponics indicated by results before and after training improved. Utilization of the yard in Madrasah Aliyah Madania Bantul already uses hydroponics with various models of hydroponic systems and it has produced hydroponic products.
