Abstract

The aren palm plant is a multi-purpose plant, where almost all parts of this plant can be utilized. One of them is nira water which can be used as sugar. his study aims to identify types of companion plants for sugar palm and agroforestry patterns used in community forests in South Tapanuli Regency. The research method used in this study was a field survey in three villages that have community forests. The results showed that there were 17 types of companion plants growing around the sugar palm plants. The pattern of the agroforestry system that occurs in the forests of South Tapanuli Regency is natural.

Abstract

IInsect pathologists' attention to the potential of entomopathogenic fungi (EPF) as inducers of plant resistance has increased in recent years. Several types of EPF that have received attention as biocontrol agents for insect pest populations include Beauveria bassiana, Metarhizium anisopliae and Trichoderma sp. because they are able to infect and kill insects directly, has a wide host range, and has been used to control various types of insect pests. Apart from being able to infect and kill insect pests, EPF can also live endophytically in plant tissue and increase plant resistance to pest attacks. The presence of EPF as endophytes is able to induce plant resistance by stimulating an increase phytohormones production. In this article, we reviewed the role of fungi as entomopathogens, the characteristics of entomopathogenic fungi, and their role as inducers of plant resistance. The review was carried out by collecting information  from original articles and related reports which reviewed the results of research on the role of entomopathogenic fungi as plant resistance inducers by including the keywords entomopathogenic endophytic fungi, resistance induction, characterization, systemic resistance and herbivorous insects. This systematic review concludes that EPF as an inducer of plant resistance is a very promising control alternative in the development of plant protection management against insect pests.

Abstract

Pasar adalah lokasi atau serangkaian kondisi yang mempertemukan pembeli dan penjual semua jenis barang yang sama dengan pasar modren dan pasar tradisional. Pasar modern (indomaret dan alfamart) adalah pasar di mana produk dijual dengan harga yang tepat dan layanan swalayan disediakan dan tidak adanya proses tawar menawar.Pasar tradisional adalah tempat bertemunya penjual dan pembeli ditandai dengan transaksi atau tawar menawar antara penjual dan pembeli langsung.Penelitian ini bertujuan untuk: 1) Mengetahui dampak keberadaan pasar modern Alfamart dan Indomaret terhadap pasar tradisional di Kabupaten Simalungun, 2) Mengetahui apakah keberadaan pasar modern Alfamart dan Indomaret menyebabkan turunnya Pendapatan pasar tradisional di Kabupaten simalungun. Metode yang digunakan dalam pengambilan sampel ini adalah sampling jenuh atau sensus. Dalam penelitian ini karena jumlah populasinya sedikit (terbatas) sehingga tidak memungkinkan untuk menggunakan sampel, sehingga peneliti mengambil jumlah sampel sama dengan jumlah populasi atau disebut dengan sensus yaitu jumlah pedagang sebanyak 30 orang. Terdiri dari pedagang sembako sebanyak 30 orang, 1 konsumen pasar modern dan 1 konsumen pasar tradisional. Hasil menujukkan bahwa dampak keberadaan pasar modern Alfamart dan Indomaret terhadap pasar tradisional di ketiga kecamatan kabupaten simalungun yaitu pendapatan pedagang pasar tradisional sebelum pasar modern yaitu Rp3.777.000/bulan turun menjadi Rp1.406.334/bulan.Sedangkan dampak bagi pedagang sembako yakni mengalami turunnya omset dan berkurangnya konsumen. Oleh karena itu, keberadaan Alfamart dan Indomaret menyebabkan menurunnya volume bahan pangan yang terjual di pasar tradisional.

Abstract

Coffee is a mainstay plantation commodity in Toba Regency which is managed independently by the community where the land around the Lake Toba area is one of the potential lands in Toba Regency for developing Arabica coffee commodities because geographically Toba Regency is located at an altitude of 900 meters to 2,200 meters above sea level and directly borders Lake Toba. The strong roots of coffee plants make this plant one of the mainstays in preserving forests, restoring critical land, preventing erosion and flooding during the rainy season. The aim of this research is to analyze the land suitability of Arabica coffee plantations in Toba Regency. The method used to analyses the land suitability by using the matching method which was carried out by matching land characteristics with parameters/ criteria for plants based on Land Map Unit (LMU). The research results show that the area of Toba Regency based on the Geographic Information System (GIS) is 207,518.31 ha. Very suitable (S1) land suitability for Arabica Coffee Plants covering an area of 67,844.68 ha (32.69%), an area of 132,030.09 ha (63.62%) has S2 suitability class and an area of 7,643.54 ha (3.68%) has marginal suitability (S3). The potential land suitability class for coffee plants in Toba Regency becomes very suitable (S1) covering an area of 67,844.68 ha or 32.69%, moderate suitable class (S2) with temperature limitation covering an area of 132,030.09 ha (63.62%) and marginal suitability (S3 with temperature limitation) covering an area of 7,643.54 ha or 3.68%. Nutrient deficiencies were corrected by adding phosphorus (P) fertilizer of 4.19 kg P/ha or 9.31 kg SP36/ha or 11.63 kg TSP/ha. Nitrogen (N) fertilizer is 75 kg N/ha or the equivalent of 166,625 Kg Urea/ha. Potassium (K) fertilizer as much as 3 kg KCl/ha. Compost fertilizer is 10.56 tons of compost/ha.

Abstract

LGBT behavior is a form of sexual deviance. Deviant sexual behavior in adolescents is caused by the way teenagers socialize freely and tends to be limitless, caused by the sexual urges that are developing in adolescents. Education about faith so far seems to have not been able to produce a generation that is steadfast, strong, and has high dedication to their religion. The method of implementing direct counseling is the method used in this community service activity. Counseling is carried out by visiting the location and providing materials related to Education on Preventing LGBT Acts in the Full Boarding Religious School Environment of Maahad Ahmadi Negeri Sembilan (SABP MANS) Malaysia. The results of the service show that the emergence of the LGBT phenomenon in schools is caused by various factors, such as lack of affection from parents, watching on social media, bad company, and having been a victim. Among the roles that the school can play include, first, providing socialization about LGBT. However, preventing LGBT students will not produce maximum results if it only relies on the school. Support and supervision from parents and the government are also very much needed, such as parental supervision of student viewing.
