Abstract

Willingness to pay (kesediaan untuk membayar) merupakan suatu keinginan seseorang untuk membayar suatu kondisi lingkungan atau evaluasi sumber daya alam dan jasa dalam rangka meningkatkan kualitas lingkungan. WTP sangat berpengaruh terhadap pendapatan rumah tangga, khususnya para rumah tangga nelayan. Hal ini dikarenakan WTP sangat erat kaitannya dengan ekologi pesisir yang dirugikan oleh pencemaran, salah satunya adalah  nilai degredasi lingkungan yang semakin tinggi. Tujuan dari penelitian ini adalah untuk mengetahui factor-faktor apa saja yang mempengaruhi Willingness To Pay (WTP) rumah tangga nelayan terhadap ekosistem mangrove di Desa Sei Nagalawan, Kecamatan Perbaungan, Kabupaten Serdang Bedagai, Sumatera Utara. Hasil penelitian menunjukkan bahwa secara parsial faktor yang berpengaruh positif secara signifikan terhadap Willingness To Pay (WTP) adalah variabel jumlah pendapatan. Sedangkan variabel usia, pendidikan dan jumlah tanggungan berpengaruh tidak signifikan terhadap kesediaan membayar konsumen (WTP). Secara simultan seluruh variabel independen berpengaruh terhadap variabel dependen dengan nilai sig F (0,00) sig ὰ (0,05).  Nilai Willingness To Pay (WTP) yang diperoleh rataan sebesar Rp 1.380.000/tahun, sedangkan total nilai Willingness To Pay (WTP) diperoleh sebesar Rp 41.400.000/tahun.

Abstract

Seeds are generally used for moringa cultivation. However, the seeds produced have a fairly hard seed coat, thus affecting germination and seed vigor. The research by immersing seeds with plant growth regulators (PGR) and a comparison of the composition of planting medium need experimentation to get the maximum PGR concentration and the right composition of the planting medium to grow. The study was conducted using a Split Plot Design with the main plots PGR consisting of Z1 (freshwater), Z2 (Coconut liquid), and Z3 (GA3). The subplot is Plant Medium consisting of M1 (soil: sand: manure-1:1:2); M2 (soil: sand: manure-1:2:1); M3 (soil: sand: manure-2:1:1). Data were examined by Analysis of Variance and continued by DMRT at α 5%. The results of the analysis showed that PGR had a significant effect on plant height, stem diameter, and root length. The composition of the planting medium caused significant differences in plant height, stem diameter, number of leaves, and fresh and dry leaf weight. The interaction between the planting medium and PGR caused differences in stem diameter at 2 and 8 weeks after planting. The recommended PGR treatment is freshwater for longer roots and taller plants. M1 planting media produced the most number and weight of leaves. The combination treatment of Z3M2 produces the largest stem diameter.

Abstract

Waste-related environmental pollution can affect health and needs to be addressed seriously.   These days, the majority of organic waste is turned into eco-enzymes and fertilizer.   In addition, insects can be used as bioconversion agents to control organic waste in homes.   The Black Soldier Fly, or BSF fly, is the insect.   The ladies of the Aisyiyah Branch in Medan Denai, North Sumatra Province, are the partners of the Muhammadiyah Development Partnership Program (PKPM) in this project.  By using maggots as a bioconversion agent and teaching Aisyiyah mothers about the use of maggots as fish and poultry feed, the program aims to turn household trash into a product of economic value, which should raise household income.  The technique employed in this activity began with socialization followed by maggot cultivation training for mothers. Direct interviews were conducted as a way to evaluate activities for Aisyiyah mothers. The results achieved were an increase in knowledge about maggots by around 75% and 25% of Aisyiyah mothers understood maggot cultivation.

Abstract

Along with the narrowness of urban land and the more expensive, it is making people in dense cities who live more in slum areas require alternative solutions to the problem of providing houses with open spaces that be used together but which are affordable and environmentally friendly, incredibly energy efficient. Co-Housing is a concept where a community group plans, finances, and builds their house together on the same land/parcel and has communal/shared spaces . The concept of Co-housing is usually applied in new housing, but given the high price of land in dense cities, this concept will be tried to be used to housing in existing slums. Where a group of people's houses are revitalized and equipped with communal/shared open spaces that are environmentally friendly, especially energy efficient so that people do not have to spend a lot of money to get all the existing facilities available in these communal/shared open spaces. The purpose of this research was to create a new form of the Co-Housing Concept of open shared spaces in environmentally friendly low-income housing. The research method used was descriptive qualitative, which was supported by the identification of land for the Co-Housing concept application and city regulations. The result of the research was a layout draft (master plan) of a new concept of open shared spaces in environmentally friendly low-income housing in several dense urban slum areas.

Abstract

Salah satu sentra produksi bawang merah di Sumatera Utara adalah desa Tongging Kecamatan merek Kabupaten Karo. Kondisi geografis desa Tongging sangat potensial bagi usaha tani bawang merah. Bawang merah Tongging terkenal dan  sangat digemari karena rasa yang gurih dan aroma yang khas. Tetapi petani bawang banyak mengeluhkan produksi rendah dan harga bawang merah yang fluktuati. Produktifitas rendah karena penggunaan input usaha tani tidak optimal karena harganya yang mahal.  sehingga petani tidak memiliki modal yang cukup dalam membeli input pertanian seperti pupuk dan obat-obatan. Hal ini berdampak pada turunnya produksi bawang merah di desa Tongging. Untuk itu tim Pengabdian masyarakat fakultas Pertanian UMSU memberikan solusi atas permasalahan yang dihadapi petani dengan memberikan pelatihan pembuatan Eco enzyme berbasis limbah Sayuran dan buah-buahan. Eco enzyme dapat digunakan sebagai pupuk atau penyubur tanah alami.  Eco enzyme juga dapat mengusir hama tanpa menggunakan pestisida kimia. Diharapkan dengan adanya pelatihan ini, petani bawang merah di desa Tongging dapat membuat eco enzyme yang dapat dimanfaatkan sebagai pupuk dan pestisida alami yang ramah lingkungan.
