<![CDATA[ABSTRACT Issues related to watershed have received primary attention in the past few decades. The hydrological conditions of the watershed area are considered crucial as a source of life. In efforts to achieve sustainable watershed management, understanding the complex hydrological dynamics is very important. The objective of this research is to simulate river discharge using the Soil and Water Assessment Tools (SWAT) model. This study was conducted in the Mamasa Sub-watershed area. The results show that the river discharge in the Mamasa Sub-watershed has increased as it approaches the outlet (downstream) through the accumulation of discharge in larger order rivers. The Mamasa Sub-watershed also experiences a trend of increasing average annual discharge at a rate of 0.74 m3/s per year. Improvement in the discharge simulation results was achieved through a calibration process using 11 parameters. The calibration results indicate that the calibrated discharge has a higher R2 value compared to the initial simulation discharge, showing that the model calibration successfully improved the quality of the expected discharge results to reach 79.50 percent. However, the calibration results still have a low R2 value, influenced by the selection of appropriate parameters and accurate observational data. Keywords: Modeling, River discharge, SWAT, Watershed]]>

<![CDATA[Salah satu potensi yang dimiliki oleh Kabupaten Polewali Mandar khususnya desa batulaya sebagian besar adalah berasal dari hutan dan lahan pertanian, akan tetapi hasil hutan saat ini belum dimanfaatkan secara optimal. Maka dari itu kami mengambil lokasi pengabdian ini. Disamping madu, produk yang dihasilkan lebah trigona adalah Bee pollen dan propolis. Masyarakat di Desa Batulaya Kecamatan Tinambung Sebagian besar mata penccaharaiaannya adalah petani baik petani padi, tanaman perkebunan atau petani aren, dengan keberadaan perkebunan yang luas tersedia kebutuhan. Permasalahan yang dihadapi oleh mitra yaitu pendampingan dan pelatihan budidaya lebah madu trigona dan pemeliharaan lebah madu, dikarenakan dalam untuk membantu perekonomian masyarakat sehingga dapat membantu lahan dipergunakan untuk lebah madu dan kelompok tani yang kurang memamhami didalam membudidayakan lebah madu dan pakan kegiatan budidaya lebah itu sendiri mengalami perkembangan jumlah koloni menjadi semakin tidak berimbang dengan luasan areal tanaman pakan yang cenderung terus menyusut akibat pengalihan penggunaan lahan masyarakat. Tujuan kegiatan program kemitraan masyarakat (PKM) ini adalah (1) Memberikan pelatihan budidaya lebah trigona, 2) Memiliki dampak positif bagi masyarakat di dalam pembudidayaan lebah madu untuk meningkatkan ekonomi masyarakat yaitu pengenalan proses pembuatan madu, 3) Mengembangkan model pemberdayaan masyarakat dalam peningkatan pengetahuan dan keterampilan. Kegiatan PKM ini juga akan menjadi wadah bagi kegiatan kampus merdeka yaitu Membangun Desa yang dapat diikuti oleh mahasiswa, dan diharapkan dapat meningkatkan Indikator Kinerja Utama (IKU) Perguruan Tinggi bagi mahasiswa untuk mendapat pengalaman di luar kampus, dosen berkegiatan di luar kampus dalam transfer keilmuan ke masyarakat, serta hasil kerja dosen dapat digunakan oleh masyarakat.]]>

<![CDATA[Kayu merupakan bahan berlignoselulosa yang dapat dirusak organisme perusak kayu. Oleh karena itu, beberapa kayu sebagai bahan bangunan perlu ditingkatkan keawetannya dengan menggunakan bahan kimia yang bersifat toksik atau repellent bagi organisme perusak kayu. Chromated Copper Arsenate (CCA) merupakan bahan pengawet kayu yang telah komersial, namun penggunaannya telah dilarang karena terbukti dapat memberikan dampak negatif pada manusia dan lingkungan. Salah satu alternatif pengganti merupakan bahan yang alami dari ekstrak bagian tertentu tanaman yang ramah lingkungan dan terbukti mampu bersifat toksik atau repellent terhadap organisme perusak kayu. Penelitian ini bertujuan untuk mendeteksi efektivitas ekstrak berbagai bagian tanaman jeringau (Acorus calamus L.) terhadap serangan rayap perusak kayu. Penelitian dilaksanakan dalam tiga tahap yaitu pengujian jumlah kadar ekstraktif terlarut n-heksan dan metanol dari bagian daun, batan, rimpang, dan akar tanaman jeringau. Ekstrak dengan konsetrasi 150 ppm diujikan ke rayap tanah untuk mendeteksi nilai mortalitas rayap. Penurunan berat kertas umpan menjadi salah satu penilaian efektivitas ekstrak terhadap rayap tanah. Hasil menunjukkan bahwa jumlah tertinggi ekstrak terlarut n-heksan dari ekstrak daun sebesar 2,82% sedangkan ekstrak terlarut metanol pada bagian rimpang sebesar 38,04%. Pengujian masing-masing ekstrak terhadap rayap tanah dengan pengumpanan selama 48 jam menunjukkan nilai mortalitas paling tinggi pada ekstrak bagian batang terlarut n-heksan sebesar 24,76% dan pada ekstrak bagian akar terlarut metanol sebesar 35,38%. Penurunan kertas umpan paling tinggi sebesar 4,24% dan 4,31% pada kontrol.]]>

<![CDATA[Sugar palm plants (Arrenga pinnata Merr) are one of the leading commodities in West Sulawesi. This plant is widely used, both as a household appliance and as a food ingredient for home industry. Sambaliwali Village has the potential to develop sugar palm plants because there are many sugar palm plants that grow naturally. Even though cultivation efforts have not yet been made, people have long used sugar palm as a source of income. The aim of this research is to find out how sugar palm is utilized by the community around the Sambaliwali Village forest. The research method is descriptive qualitative with data analysis techniques according to Miles and Hubberman. The sample was determined using purposive random sampling with 38 sugar palm farmers as respondents from Sambaliwali Village. The results of the research show that the people of Sambaliwali Village process palm sap and palm leaves. Palm sap is made into molding sugar and liquid sugar, while palm leaves to be made into broom sticks. Palm sap processing still uses traditional methods. There has been no effort to cultivate palm plants, until now people have only cultivated sugar palm which grows naturally in the surrounding forest area. Key words: Sugar palm, palm sap, use of forest products]]>

<![CDATA[Biomass and carbon are forest products stored in plants as a result of photosynthesis. Gmelina arborea, as a community forest plant in Mirring Village, produces biomass and stored carbon, influenced by various factors including diameter and plant height. The purpose of this study was to analyze the linear relationship between the diameter and height of Gmelina arborea and its biomass and stored carbon. The method used was a survey and measurement of the diameter and height of 35 Gmelina arborea trees, followed by an analysis of their linearity and the coefficient of determination (R²) generated from the relationship analysis. The results showed a very strong linear relationship between diameter and biomass and stored carbon, and a fairly strong relationship between height and biomass and stored carbon. The R² values from both relationship analyses were 0.741 and 0.908, respectively. This indicates that the diameter and height of Gmelina arborea can explain the variation in biomass and stored carbon values well.]]>

<![CDATA[Global warming has a huge negative impact on all living things, both humans, animals and plants. The cause of global warming is due to an increase in the concentration of carbon dioxide (CO2). Agroforestry pattern community forests have a good role in efforts to reduce gas emissions in the atmosphere. Vegetation found in community forests can absorb carbon through photosynthesis and release carbon through respiration, in the process of photosynthesis vegetation produces O2 and energy and some is stored in the form of biomass. This study aims to determine the potential of biomass and carbon stored in agroforestry-patterned community forests in Polewali Mandar District, West Sulawesi. Data collection was carried out in 9 villages in Bulo District with a total of 27 plots measuring 20 x 20 m. The data collected included tree diameter, tree height and tree species. data analysis using allometric equations according to tree species to obtain biomass values. while for the stored carbon value obtained from biomass products of 0.47. The results showed that the plant that dominated the highest value of biomass and carbon was durian. The total biomass in the community forest with the agroforestry pattern in Polewali Mandar Regency is 90.62 ton/ha while the total value of stored carbon is 42.59 ton/ha.]]>
